Medicine, health care, and the wider social meaning and management ofhealth are undergoing major changes. In part this reflects developmentsin science and technology, which enable new forms of diagnosis, treat-ment and delivery of health care. It also reflects changes in the locus ofcare and the social management of health. Locating technical develop-ments in wider socio-economic and political processes, each book in theseries discusses and critiques recent developments in health technologiesin specific areas, drawing on a range of analyses provided by the socialsciences. Some have a more theoretical focus, some a more applied focusbut all draw on recent research by the authors. The series also lookstoward the medium term in anticipating the likely configurations ofhealth in advanced industrial society and does so comparatively, throughexploring the globalization and internationalization of health.

Series Editors’ Preface

Medicine, health care and the wider social meaning and management ofhealth are undergoing major changes. In part, this reflects developmentsin science and technology, which enable new forms of diagnosis, treat-ment and the delivery of health care. It also reflects changes in the locusof care and burden of responsibility for health. Today, genetics, infor-matics, imaging and integrative technologies, such as nanotechnology,are redefining our understanding of the body, health and disease; at thesame time, health is no longer simply the domain of conventionalmedicine, nor the clinic. The ‘birth of the clinic’ heralded the processthrough which health and illness became increasingly subject to thesurveillance of medicine. Although such surveillance is more complex,sophisticated and precise as seen in the search for ‘predictive medicine’,it is also more provisional, uncertain and risk laden.

At the same time, social management of health itself is losing itsanchorage in collective social relations and shared knowledge and prac-tice, whether at the level of the local community or through state-fundedsocialised medicine. This individualisation of health is both culturallydriven and state sponsored, as the promotion of ‘self-care’ demonstrates.The very technologies that redefine health are also the means throughwhich this individualisation can occur – through ‘e-health’, diagnostictests and the commodification of restorative tissue, such as stem cells andcloned embryos.

This series explores these processes within and beyond the conven-tional domain of ‘the clinic’, and asks whether they amount to aqualitative shift in the social ordering and value of medicine and health.Locating technical developments in wider socio-economic and politicalprocesses, each book discusses and critiques recent developments withinhealth technologies in specific areas, drawing on a range of analysesprovided by the social sciences.

The series has already published 17 books that have explored many ofthese issues, drawing on novel, critical and deeply informed researchundertaken by their authors. In doing so, the books have shown how theboundaries between the three core dimensions that underpin the wholeseries – health, technology and society – are changing in fundamentalways.

This new book contributes to one of the series’ themes, namely, theexploration of recent developments in health technology innovation andhow these redefine the meaning of a condition and its framing andtreatment in the clinic, as was seen, for example, in Mesman’s book onneonatology (2008). In this volume, the boundaries and actors defining‘the clinic’ are much more broadly based, reflecting the multiple clinicaland other actors involved in managing and treating the condition knownas ‘dystonia’, a neurological disorder characterised by uncontrollablemuscular contraction. Gardner describes the ways in which we need torevise our understanding of the ‘clinical gaze’ (derived from Foucault’swork) whereby not only patients but also their wider social circum-stances and behaviour are included in both assessment and treatmentregimes. The technology in question used to treat dystonia is deep-brainstimulation (DBS). The book examines the use of DBS in paediatricclinics and the emergence of what Gardner calls a ‘proto-platform’ – adiverse range of technical, spatial, professional and architectural contexts– within which DBS is adopted and performed. It shows how theadoption of DBS is anchored not simply in the perceived merits ofDBS as a technology but equally importantly within a wider cultural setof judgements and expectations about behavioural norms and practices,and ways of understanding that drive patient-centric treatment.

The book makes an important contribution to our understanding ofmedical innovation through bringing together in a novel way ideas

drawn from a Foucauldian tradition and from science and technologystudies. It is written in a very engaging style, and its story is rich andinformative. Readers will find this book an invaluable contributiontowards our understanding of the complex relations between socio-technologies, health and social practices, and, in particular, how theseare increasingly combined and layered as diagnostic and treatment ‘plat-forms’, involving multiple forms of evidence, disciplinary languages andprofessional practitioners. It also offers a timely critique of the turntowards and ideals of patient-centred medicine by showing how this isenacted through the platform that coordinates and choreographs thevery patient/disorder relationship.

1Introduction: ‘Where Great Need

Meets Great Uncertainty’

Dystonia is a neurological disorder characterised by uncontrollable mus-cular contraction. In severe cases, this results in painful and crippling bodypostures. In 2003 the medical device manufacturer Medtronic gainedregulatory approval to market their deep brain stimulation (DBS) tech-nology as a therapeutic intervention for dystonia. Other, more standardinterventions for managing severe dystonia are generally considered to becrude and ineffective. Medications provide some relief for a small numberof sufferers, but for many they are ineffective or the side effects areintolerable. Ablative surgery, which involves carefully destroying a specificsection of brain tissue, may have some therapeutic effect, but this is oftenshort term; the surgery will need to be repeated, and as more brain tissue isincrementally destroyed, important functions will be irreversibly impaired.As the recent report Novel Neurotechnologies (2013) by Nuffield Councilon Bioethics1 states, dystonia is one of many neurological conditions forwhich there is ‘a great need’ for new, safer, and more effective therapies.There is a considerable hope among clinicians and sufferers, then, that

DBS will prove to be such a therapy. According to proponents, it isadjustable and reversible (unlike ablative surgery), and it has proved tobe remarkably effective in managing the symptoms of other neurologicaldisorders such as Parkinson’s. Indeed, the Nuffield Council’s report iden-tifies DBS as one of several highly promising novel therapeutic innovationsin neurology.

The report also highlights the ‘great uncertainty’ surrounding thesepromising innovations. Despite having undergone clinical studies as partof the regulatory approval process, there is a perceived insufficiency indata concerning the safety and clinical effectiveness of DBS for dystonia.For example, while some sufferers have experienced a dramatic reductionin dystonic movements with DBS, data on the actual functional gainsexperienced by patients are limited, and it is clear that some DBSrecipients continue to experience marked functional difficulties in theirday-to-day life (Gimeno and Lin 2016). And while the incidence ofserious short-term adverse effects appears to be low, there is someuncertainty over the long-term effect of stimulating areas of the brainthat may be implicated in cognition and mood. For these reasons, theNuffield Council’s report suggests that the use of the DBS technique forsome disorders such as dystonia occupies a tenuous half-way pointbetween experimental therapy at one extreme and routine clinical inter-vention at the other. This sense of precariousness is heightened by thehigh cost of providing DBS, particularly when healthcare authorities arebecoming increasingly concerned with cost-effectiveness.

For clinicians who wish to provide DBS therapy as a routine clinicalintervention, these uncertainties present considerable challenges. Thisbook is based upon a study, using observations and interviews, of aspecialist team of clinicians as they attempt to address a ‘great clinicalneed’ while managing such ‘great uncertainties’. The team, which will bereferred to as the PMDS, is based in the UK and is one of a few teamsworldwide that are currently providing DBS therapy to children andyoung people with dystonia. This book explores several specific chal-lenges encountered by the PMDS team members, and it explores howteam members attempt to manage and overcome these challenges duringtheir day-to-day clinical work. A premise of this book is that the team’sresponse to these challenges is a vital part of the innovation process.

Indeed, the team represents what has come to be understood as a crucialand problematic stage in the translation of biomedical science intoeffective clinical therapies: the clinical adoption and implementationstage. There has been an emerging interest in the ‘adoption’ of newtherapies and systems within ‘the clinic’ among policy makers and healthservice researchers, prompted by various concerns relating to, for exam-ple, the failed uptake of officially mandated innovations, perceivedtechnology creep, and variable clinical service quality across healthcareproviders. Actors tasked with facilitating innovation in highly promis-ing, emerging areas of medicine (such as regenerative medicine) havealso delineated ‘adoption’ as a key concern. The activities of the PMDSteam, therefore, can provide some important insights into the specifictypes of challenges that may be associated with ‘adoption’, and how suchchallenges are managed during day-to-day clinical work. Hence, in thisbook I use the PMDS as a case study for examining innovation at theadoption stage.

The book therefore contributes to sociological understandings of thenature of innovation in healthcare. Drawing on a theoretical approachthat is informed by medical sociology and Science and TechnologyStudies (STS), and by building upon work within innovation studies,I use the activities of the PMDS to reflect on the processes that underliesocio-technical change in healthcare. I introduce a novel theoreticalconcept: socio-technical proto-platforms, which brings to light the com-plex interweaving of heterogeneous social and technical elements thatconstitute medical innovation.

And, in doing this, I reflect on how understandings of health andillness are affected by innovation: the PMDS provides a valuable oppor-tunity to examine how the implementation of a new medical technology(DBS) affects understandings of health and illness (dystonia) in an actualclinical setting. Indeed, the second premise of this book is that if wewant to understand the social implications of new medical technologies,we need to explore the organisational forms – or proto-platforms – thatemerge around them as they are adopted and implemented. Contrary tosome of the more speculative commentary on the impact of novelneurotechnologies on perceptions of health and illness, this book pro-vides an account of clinical work in which, due to the influence of

1 Introduction: ‘Where Great Need Meets Great Uncertainty’ 3

Page 19: Health, Technology and Society€¦ · Health, Technology and Society Series Editors Andrew Webster Department of Sociology University of York York, UK Sally Wyatt Royal Netherlands

patient-centred medicine, dystonia is enacted in multiple ways; in somepractices as a ‘biomedical’ phenomenon, and in other practices as a‘social’ concern. In light of this, and as a way of anticipating the socialimpact of the much-championed ideals of patient-centred medicinemore generally, the book introduces the notion of the broad clinicalgaze as a way of rethinking the clinical gaze described by Foucault. Thebroad clinical gaze, I suggest, represents an extension of medical power;power that is disciplining, and that has both constraining and productiveeffects.

This book can be seen as both an account of medical innovation inpractice, and an account of the impact of the patient-centred ideals onday-to-day clinical work and perceptions of health and illness. Byexploring the intersection of these two themes, the book provides aunique analysis of medically mediated socio-technical transformation.The specific argument and structure of the book is presented towardsthe end of this introductory chapter. Before presenting these, how-ever, it is necessary to provide a more substantial background onDBS, the neurological disorder dystonia, and the PMDS clinicalteam. This will enable me to argue, in more precise terms, why thePMDS represents such a fruitful case study for a sociological study ofinnovation.

Deep Brain Stimulation (DBS)

DBS is a technique in which a pacemaker-like device is used to deliverconstant electrical stimulation to areas deep within the brain. It is usedto reduce the severity of symptoms for a range of neurological disorders.According to current models of the brain, such neurological disordersare the consequence of pathological or damaged brain structures whichinduce abnormal levels of neural activity. This activity disrupts normalsignalling pathways within the central nervous system, leading touncontrollable motor symptoms such as rigid and stiff muscles or shak-ing and flailing limbs (Montgomery and Gale 2008). The exact way inwhich DBS alleviates such symptoms is not known. One explanation is

4 Rethinking the Clinical Gaze

Page 20: Health, Technology and Society€¦ · Health, Technology and Society Series Editors Andrew Webster Department of Sociology University of York York, UK Sally Wyatt Royal Netherlands

that by swamping the problematic brain structures with electrical noise itessentially masks the pulsating, cyclic neural activity that would other-wise trigger the motor symptoms (Montgomery and Gale 2008). DBS isnot, then, a cure. It does not repair abnormal brain structures and it doesnot prevent the progressive degradation of brain tissue associated withsome neurological disorders. So while it may be effective in enablingpatients to regain some control over the movement of their body, whenelectrical stimulation ceases, so too does its therapeutic effect.

DBS is currently being used in several movement disorder therapies.Within several regulatory jurisdictions, including the European Unionand the USA, regulatory agencies have permitted DBS therapies forParkinson’s, essential tremor, and dystonia. Generally, due to the per-ceived risks and the high cost of DBS, it is reserved for severe cases ofthese conditions where other, more usual treatments, have failed toprovide adequate therapeutic relief. Parkinson’s is by far the mostcommon disorder treated with DBS: diagnoses of Parkinson’s are pre-valent in developed countries, it is progressive, and long-term medicinaltreatment fails in up to two-thirds of patients (Marsden and Parkes1977, 348); hence, according to the device manufacturer Medtronic,over 100,000 people worldwide are using DBS to manage the motorsymptoms of Parkinson’s (Medtronic 2015).

Some cases of epilepsy are being treated with DBS (Boon et al. 2007),and researchers are also exploring the ability of DBS to treat severe casesof psychiatric illnesses: in the European Union, DBS has been approvedfor the treatment of severe obsessive-compulsive disorder (OCD), and inboth Europe and the USA, pilot trials assessing DBS as treatment fordepression have recently been completed (Mayberg et al. 2005). In thepast, severe cases of these motor and psychiatric disorders that failed torespond to medicine-based therapies would have been treated withablative surgery. Proponents of DBS argue that unlike ablative surgery,DBS does not cause irreversible damage to brain structures, and adverseeffects are therefore less likely, or easier to manage if they do arise(Benabid et al. 1991; Limousin et al. 1995).

Specialised technology is needed to deliver DBS. Electrical stimula-tion is delivered to the target areas within the brain by at least one lead.In an operation that lasts between three and six hours, a neurosurgeon

1 Introduction: ‘Where Great Need Meets Great Uncertainty’ 5

Page 21: Health, Technology and Society€¦ · Health, Technology and Society Series Editors Andrew Webster Department of Sociology University of York York, UK Sally Wyatt Royal Netherlands

carefully threads the lead into the brain so that the electrodes at one endare placed within the target area. The other end of the lead is attached toa flexible extension wire, threaded under the skin from the top of thescalp, down the side of the neck to the chest (See Fig. 1.1). At this point,it is attached to a neurostimulator, also known as an implantable pulsegenerator (IPG), which has been implanted under the skin (Talan 2009,xiii). DBS therapies are either monopolar, where one lead is inserted onone side of the brain, or biopolar, where two or more leads are used tostimulate both sides of the brain. The specific electrode contact areawithin the brain depends on the condition being treated, but in motordisorders the target area is one of several structures that make up thebasal ganglia region.

The neurostimulator (often referred to as an implantable pulse gen-erator, or IPG) is very similar in appearance and function to a cardiacpacemaker, producing a constant electrical pulse, albeit at a much higherfrequency than that used to regulate the beating of a heart. A battery

Page 22: Health, Technology and Society€¦ · Health, Technology and Society Series Editors Andrew Webster Department of Sociology University of York York, UK Sally Wyatt Royal Netherlands

makes up most of the bulk of the neurostimulator, and depending on themodel, it may be either rechargeable or non-rechargeable. In rechargeablemodels the battery is recharged transcutaneously: the patient (or a care-giver) presses a recharging paddle against the area of skin that covers theneurostimulator, ideally once a day for half an hour. Non-rechargeablemodels tend to be used for patients who may have difficulty adhering to arecharging schedule. These batteries last between two and four years, afterwhich the entire neurostimulator is surgically replaced.

Once the components have been implanted within the patient, aclinician can programme the neurostimulator via remote control: it canbe switched on and off, the frequency of stimulation can be altered, andspecific electrodes can be activated. It may take several weeks of trial anderror adjustment before the most efficacious stimulation parameters foreach particular patient have been determined (Ostrem and Starr 2008,322). In some cases (particularly with Parkinson’s) the patient will be givena remote programmer to enable them to have some control over theimplanted device. Importantly, after the device has been implanted andthe initial optimal stimulation parameters have been identified, DBSpatients require long-term skilled clinical attention: six-monthly follow-upassessments are necessary to ensure that stimulation parameters are indeedstill optimal (they often require fine tuning); hardware failures, such asbroken or migrating leads, are not uncommon; and of course, for thosepatients with non-rechargeable stimulators, a neurosurgical team is neededto replace the stimulator at least every four years.

For social scientists, the emergence of DBS represents an excellentopportunity to explore the social dynamics of innovation, and indeedthe tensions associated with biomedicine and society more generally. Itis, as the Nuffield Council report states, considered to be a highlypromising technological development. Indeed, DBS therapy forParkinson’s in particular is currently viewed as a sensible and generallyeffective intervention for patients who fail to respond to medicine-basedtherapies (Bell et al. 2009; Deuschl et al. 2006, 578). Most Parkinson’spatients experience a useful reduction in the severity of their symptoms,and some patients have had dramatic improvement in their condition.Indeed, some commentators have heralded DBS as providing ‘a new lifefor people with Parkinson’s’ (Chou et al. 2011), and stories of previously

1 Introduction: ‘Where Great Need Meets Great Uncertainty’ 7

Page 23: Health, Technology and Society€¦ · Health, Technology and Society Series Editors Andrew Webster Department of Sociology University of York York, UK Sally Wyatt Royal Netherlands

housebound patients with debilitating symptoms subsequently regainingindependence and self-confidence with DBS are not uncommon. And,despite the high cost of DBS, there is also emerging evidence to suggestthat for the long-term treatment of Parkinson’s it is more cost-effectivethan the best alternative treatments (Bell et al. 2009; Fraix et al. 2006).

However, as with many new technological developments in medicine,DBS is linked with various risks and uncertainties. Despite the apparentsuccess of DBS for treating motor disorders, it is associated with a range ofadverse effects, some of which can be severe. There are those adverse effectsthat relate to the implantation of the components, such as intra-operativecerebral haemorrhaging and post-operative infection, and there are thoserelated to the actual therapy itself, such as slurred speech and a range ofso-called psycho-social effects. In DBS therapy for Parkinson’s, theseinclude mood elevation, anxiety, aggression, and cognitive dulling(Synofzik and Schlaepfer 2011, 3–4). In the longer term, some DBSpatients have experienced feelings of aimlessness, despair over the yearslost to their illness, marital problems resulting from mood changes, andsuicide (Agid et al. 2006; Schüpbach et al. 2006). It is not clear whetherthese long-term effects are directly linked to electrostimulation itself or ifthey are the consequence of the major life changes resulting from the rapidtransition from a severely impaired state to an able state (Bell et al. 2009).There are uncertainties around the frequency and severity of such effectsand also around the efficacy of DBS therapies: while many patients withParkinson’s or dystonia will respond positively to DBS, some patientsexperience no benefit whatsoever, and identifying appropriate candidatesfor DBS interventions can be difficult (Schlaepfer and Fins 2010; Synofzikand Schlaepfer 2011).

The ‘great promise’ surrounding DBS, which is no doubt providingsignificant momentum to the DBS enterprise (Borup et al. 2006), has alsoraised concerns among commentators. As with many novel biomedicaldevelopments, DBS is subject to a fair amount of media-generated hype.The media has tended to produce ‘over-optimistic portrayals’ of DBS,focusing on positive outcomes and dramatic, individual cases whileneglecting to explore the actual, more subtle benefits experienced by themajority of people who are undergoing treatment (Gilbert and Ovadia2011, 2). Racine and colleagues (2007) argue that by reporting

8 Rethinking the Clinical Gaze

Page 24: Health, Technology and Society€¦ · Health, Technology and Society Series Editors Andrew Webster Department of Sociology University of York York, UK Sally Wyatt Royal Netherlands

predominantly on DBS ‘miracle stories’, the media is creating unrealisticexpectations among the public and prospective patients, and thus produ-cing additional pressures for clinicians delivering DBS therapies. This isparticularly problematic with DBS as it often represents the last hope forpeople with debilitating symptoms, and who have failed to improve withother available treatments (Bell et al. 2009).

Some commentators have drawn attention to the role of commercialinterests in disseminating information on DBS technology. The majorproducer of DBS equipment is the Minneapolis-based medical devicemanufacturer Medtronic. According to their 2014 annual report, world-wide sales of DBS technology constituted a sizeable chunk of their USD1.9 billion in net revenues in their neuromodulation division for thefinancial year (Medtronic 2014b). Fins and Schiff (2010) argue that theinterplay of market forces and scientific inquiry within DBS research hasresulted in potentially dangerous conflicts of interest. Medtronic, forinstance, has been accused of misusing a regulatory exemption in orderto facilitate the dissemination of their DBS technology into therapy for apsychiatric disorder (Fins et al. 2011). And, from a more speculative,philosophical perspective, DBS has been implicated in the ‘continuousmarch of technologies that invade and transform the body’, bringing uscloser to an era of ethically contentious intelligent design, cyborgs, andmind/machine interfaces (Hester 2007, 255). Such accounts renderDBS a small but definite movement towards neurotechnologies with apotential to significantly affect that which we think of as ‘human’(McGee and Maguire 2007).

Thus, DBS is not only the source of great promise and hope, it is alsothe subject of apprehension. Indeed, it exemplifies the complex tensionsassociated with biomedicine in contemporary society more generally: aconviction in technology-orientated solutions, a drive to alleviate suffer-ing, a suspicion of commercial interests, doubts over the ability ofregulatory initiatives and anxiety over a precarious future. For thesereasons, DBS is an excellent topic of sociological investigation. Forthose of us who are interested in exploring the dynamics of medicalinnovation, such as how the social and technological aspects of medicinemay shape one another and intertwine, the relationship between devel-opments in medicine and wider social and political context, and the

1 Introduction: ‘Where Great Need Meets Great Uncertainty’ 9

Page 25: Health, Technology and Society€¦ · Health, Technology and Society Series Editors Andrew Webster Department of Sociology University of York York, UK Sally Wyatt Royal Netherlands

ethical challenges presented by new medical technologies, DBS providesan illuminating case study.

Deep Brain Stimulation in Social ScienceResearch

A small body of work has explored what we might call the ‘social’ dimen-sions of DBS. Some of this has been conducted by French clinical teams aspart of their post-operative long-term surveillance of patients receivingDBS for Parkinson’s (Agid et al. 2006; Schüpbach et al. 2006). Thesefollow-ups have involved standardised quality-of-life and psychologicalassessments, along with ‘qualitative psychological observations backed-upby a semi-structured psychiatric interview’ (Agid et al. 2006, 410). It hasbeen these studies that have identified the various ‘psycho-social’ problemsencountered by some DBS recipients: marital problems, feelings of despairover the years lost to the illness, persistent negative anticipation of thefuture, and a loss of aim in life. Some patients, the authors note, have alsoexperienced a sense of being dehumanised due to their reliance on aforeign, implanted mechanical technology; a feeling of being ‘an electronicdoll’ (Agid et al. 2006, 412). Some of these same patients were interviewedby the sociologist Elsa Gisquet (2008), who highlighted the day-to-daychallenges faced by people with Parkinson’s. Some, she noted, lamentedtheir reliance on a specialised medical technology, others experiencedtroubling changes in mood which they attributed to the therapy, andsome were frustrated that DBS was not providing greater relief. Gisquetgoes on to suggest that DBS therapies may pose ‘a unique form ofbiographical disruption’ for patients, and suggests that ‘a period of adap-tion is required so that patients become used to their new capacities andaccept the limits of the treatment’ (Gisquet 2008, 1850).

The experiences of these patients, and clinicians’ responses to them,have been more carefully interrogated by Baptiste Moutaud as part of hisethnographic study of one of the French clinical centres providing DBS(Moutaud 2011, 2015). Moutaud paid close attention to the way inwhich clinicians drew upon various explanatory models to make sense oftheir patients’ responses to DBS. He notes, for example, that the

clinicians were able to carefully delineate patients’ psycho-social problemsas being a consequence of their inability to reintegrate into ‘normal life’,rather than being a direct side effect of the stimulation. This enabled themto frame DBS as ‘successful’, and in the process they effectively drew uponand perpetuated a model of personhood characterised by a mind/bodyrupture (2011, 186). Patients, in other words, were understood as havinga successfully managed neurological disorder, and as having a distressedmind that necessitated further psychological care. Moutaud also exploredhow patients themselves drew upon various models of personhood tomake sense of their experiences. In contrast to their clinicians, somepeople with Parkinson’s attributed their psycho-social problems to DBSand its direct effects on the brain. Moutaud argues (Moutaud 2011, 190)that these patients are, in effect, buying-into and reinforcing a naturalistic,neuroscientific discourse that equates behaviour and emotion with neuralstructures. Similarly, patients undergoing DBS for OCD (who were alsoincluded in Moutaud’s study) employed biological models to understandtheir illness. These patients made sense of their OCD in terms of patho-logical brain circuits rather than, say, drawing upon psychoanalytic mod-els that relate OCD to obsessional neuroses. Moutaud’s study, then,illustrates how DBS can influence how human actors make sense ofhealth, illness, and personhood. Indeed, like other neurotechnologies (asI discuss in Chapter 8), it has been implicated in perpetuating brain-basedexplanations of the self.

Moutaud’s work (e.g. Moutaud 2015) also highlights other tensions.Patients, he noted, become entwined in a technologically mediatedrelationship with clinicians. Some experience a feeling of ‘loss of control’as their DBS system often requires alteration and adjustment, and this,in turn, requires the skill and experience of clinicians. The clinical teamthus had to create a care plan for patients that took this reliance intoaccount, and that could also attend to patient dissatisfactions andpotentially disabling adverse effects. This created complex service orga-nisational patterns involving various types of staff members (neurolo-gists, psychiatrists, psychologists, social workers, etc) that, Moutaudargues, has implications for the subsequent diffusion of the technology:the complexity and cost of the services may discourage other centresfrom establishing a similar service, while a slimmed-down service may be
