REPORT OF THE INTERNATIONAL SURVEY OF CEREBRAL PALSY REGISTERS AND SURVEILLANCE SYSTEMS 2015
Cerebral Palsy (CP) registers and populations based surveillance systems (hereto referred to as
‘surveillance programs’) have reported on trends in CP since the 1950s. The number of surveillance
programs worldwide is increasing and currently nearly 40 exist worldwide.
The first International Survey of Cerebral Palsy Registers and Surveillance Systems was completed in
2009, in preparation for the World CP Register Congress in Sydney. Results were presented at the
Congress, held as part of the International Cerebral Palsy Conference. A report of the survey was also
published online. This second International Survey was conducted five years on, to provide an update on
the state of the CP surveillance programs in operation around the world. The purpose of the survey was
to describe CP surveillance programs and identify similarities and differences across topics of importance
for the relevance and sustainability of, and collaboration between, surveillance programs.
The original online “Survey Monkey” survey was updated, expanded and an invitation to participate was
sent by email to all CP surveillance programs known to the study authors (n=38). Participants were
encouraged to forward the survey link (https://www.surveymonkey.com) to any other known
surveillance programs. The survey was available for four weeks in June-July 2014 and included seventy-
one questions related to issues of governance and funding, aims and scope, definition of CP,
inclusion/exclusion criteria, ascertainment strategies, data collected and research collaboration
(Appendix 4). Participants were requested to supply a copy of their data collection sheet in English and a
list of publications arising from their surveillance programs.
The Cerebral Palsy Alliance Ethics Committee, a recognised National Health and Medical Research Council
(NHMRC) Human Research Ethics Committee (HREC: EC 00402) granted an exemption from ethical review
given the negligible risk posed by the survey. Informed consent of the participants was implied by survey
completion.
This report provides a summary of the survey forms completed. Descriptive statistics are provided in the
report. For items where multiple responses were possible, percentages can exceed 100%.
Preliminary results were presented at the Cerebral Palsy Register workshop at the American Academy of
Cerebral Palsy and Developmental Medicine Conference in San Diego, USA, September 2014, and will be
published in an Australian Cerebral Palsy Register supplement to Developmental Medicine and Child
Neurology.

details.

1. Participants
There was a high response rate to the survey (71%) and special thanks are given to each of the 27
participating programs listed below. A brief description of each of these groups and relevant contact
details have been provided in Appendix 1. See Appendix 4 for a copy of the original survey. If other groups
would like to participate their data can be added to the electronically available document at any point.
Participants represented 11 countries and three geographical regions (Australia, Europe and North
America) and included three collaborations between registers (SCPE, ADDM, ACPR). The earliest
surveillance group commenced in 1960, while the newest program began in 2012. The earliest data
available is from the birth year 1954.
Non-responders included 10 European programs and one program from Australasia. Two programs (*)
reported that they ceased operation in recent years due to a lack of funding. For all subsequent survey
results, results and % of responses refer to the 25 currently operating surveillance programs that
participated in this survey, unless otherwise stated.

2. Aims of Surveillance Programs
Total responders n=25 programs
There was considerable common ground regarding the aims of surveillance programs. Most listed
multiple aims, which can be described within the key domains below. See Appendix 1 for further detail.
i. Resource for cerebral palsy research (n=25)(100%): provide a resource for CP research e.g.
identifying potential subjects, identifying CP as a long term outcome and gauging representativeness
of study samples;
ii. Surveillance (n=23)(92%): provide surveillance of prevalence, time trends and survival by key
characteristics;
iii. Prevention (n=17)(68%): aim to prevent CP by identifying possible aetiological pathways and
reporting prevalence over time with the introduction of preventive strategies;
iv. Planning (n=12)(48%): provide information to assist with the planning of services for people with CP;
v. Information (n=5)(20%): provide information about CP with a view to raising community awareness
of the condition and act as an information source for families.
3. Definition of Cerebral Palsy
Total responders n=24 programs
Five definitions of CP were utilized, with many surveillance programs using more than one definition. SCPE (2000) was most cited (63%), followed by Rosenbaum (2007) (54%) (Table 1). Table 1: Definitions of CP utilised used by surveillance programs (n)

North America - 4 1 2 -
Note: MADDSP and ADDM Network use the definition of Rosenbaum et al (2007), modified to include children with a brain damaging event after 28 days of life (post-neonatal CP).
4. Denominator and registration numbers
Total responders n=25 programs
There was significant variability in demographic criteria determining eligibility (where they are born,
where they currently reside, where they resided at time of birth), with many programs using multiple
criteria. Denominators reported included live births (83%), children living in area at a specified age (30%),
neonatal survivors (26%), one year survivors (9%) with some programs having access to more than one
denominator (Table 2).

5. Funding Total responders n=25 programs
Funding for surveillance programs was received from various sources. Some groups reported multiple
funding sources and one program received no specific funding for CP surveillance activities (Table 3).
Table 3: Funding sources Programs reporting this method (n) (%)
Government funding (health/education/research) 18 72%
Not for profit/charitable organisations 3 12%
Other external funding sources 3 12%
No specific funding 1 4%
Note: Multiple responses possible thus percentages do not equal 100
Two surveillance programs have recently ceased operations, in 2009 and 2010, both due to a lack of
further funding. One program cited policy change regarding consent as a direct contributor. As a
university-based surveillance program without direct access to families, the program relied on clinical
staff to obtain consent. Registration was lower than expected and the program was no longer viable as a
population based program.
6. Eligibility
Total responders n=22 programs
To help improve precision in identification and inclusion/exclusion of cases, programs reported the use of
published definitions of CP. Some programs reported more than one definition. The “What constitutes
CP?” and updated “What constitutes CP in the 21st
century?” papers from Badawi et al and Smithers-
Sheedy et al were most often used (55% of surveillance programs), and 45% of programs used the SCPE
definition and decision tree (Table 4).

Surveillance programs were specifically asked about several eligibility issues which have historically varied
between programs.

6.1 Minimum age of survival
Total responders n=24 programs
42% (n=10) of surveillance programs had a minimum age of survival for inclusion of a case, ranging from 1
– 16 years. Data for each surveillance program can be found in table 5.
6.2 Minimum severity criteria
Total responders n=24 programs
46% (n=11) of surveillance programs had a minimum severity criteria for inclusion of a case. Activity
limitation (due to motor impairment) (n=4) and GMFCS level I (n=4) were most commonly reported. Data
for each surveillance program can be found in Table 5.
6.3 Post-neonatally acquired CP
Total responders n=24 programs
96% of surveillance programs include, but differentiate, post-neonatally acquired CP cases in their data
set. There was considerable variation in the upper age limit for timing of post-neonatally acquired brain
injury, and whether age at acquisition of brain injury is recorded. Data for each surveillance program can
be found in Table 5.

6.4 Hypotonic CP
Total responders n=24 programs
54% of surveillance programs, all based outside Europe, include hypotonic CP cases in their data set.
Hypotonic CP was not consistently defined. Some cited definitions of hypotonic CP included:
Hypotonia (not associated with intellectual disability) with hyper-reflexia
Static encephalopathy, changes to tone (low), posture and movement
ADDM CP Network (US): “Hypotonia” AND a CP diagnosis (as per ADDM case definition criteria),
or a diagnosis of “hypotonic CP” made by a qualified examiner, e.g. paediatric neurologist,
developmental paediatrician. Including these cases allows for excluding them in order to
compare CP subtypes across surveillance programs
12
7. Consent requirements
Total responders n=25 programs
The consent requirements for collecting, recording and maintaining a data set varied across the different
surveillance programs (Table 6). Some surveillance programs received permission from a government
body, usually with health or education authority, while other programs require individual/parent
permission/consent. Several surveillance programs use a combination of consent methods each
addressing different activities of the program. Most (80%) surveillance programs had provisions for
allowing contact with registered cases to invite them to participate in future research activities.

8. Identification of new cases
Total responders n= 25 programs
Survey programs were asked to report methods used to identify new cases, specifically sources of case
data and methods of ascertainment. Many different methods were used, with 68% of surveillance
programs using four or more different methods, and 84% using five or more different data sources (Table
7). Medical professionals were the most commonly reported source of data (100% of programs).

9. Data collection
Total responders n= 24 programs
9.1 Age at data collection
The age at which data items were collected varied greatly between surveillance programs, ranging from
at first diagnosis (birth onwards) to older adulthood, depending upon the program’s purpose and on the
geographical region (Table 8).
9.2 Completeness of ascertainment
Ascertainment of data was generally considered complete by most surveillance programs between 5 -8
years of age (Table 8). 46% of programs have a procedure for assessing the completeness of population
ascertainment. Six programs reported comparing rates to long standing population registers anticipated
to have similar rates of CP, three compared to other registers/health care sources, and two used capture-
recapture techniques. Short of house to house surveys there is no gold standard for assessing
completeness of ascertainment.

10. Classification of CP subtypes
Total responders n= 24 programs
10.1 Type of CP
Significant geographical variation existed regarding the classification of CP based on the type/s and
topographical pattern of the movement disorder, reflecting the different definitions used for CP (Table 9).
Table 9: Type of CP – number of programs reporting (n)
Dyskinetic Ataxic Hypotonic Unknown/ Unclassifiable

Various miscellaneous types of CP and notes regarding type were reported:
CPUP: SCPE subtypes mandatory, Swedish classification (Hagberg 1975) optional
Western Sweden: tetraplegia is used for most severe form of bilateral spastic CP
UK: Northern Ireland CP Register: mixed spastic-dyskinetic; mixed dyskinetic-spastic; choreo-
athetoid; North of England Collaborative Cerebral Palsy Survey: choreo-athetoid
North America MADDSP/ADDM: miscellaneous: spastic CP NOS, mixed spastic/non-spastic CP;
The Cerebral Palsy Research Registry: hypertonicity/spastic
10.2 Topography of spastic CP
Within spastic CP subtypes, all European programs used at a minimum ‘unilateral’ and ‘bilateral’ to
classify topography. In Australia, monoplegia/hemiplegia/diplegia/triplegia/quadriplegia were used
consistently, which can be grouped to match European categories when required. Most North American
programs used both systems (Table 10).

Total responders n= 24 programs
11.1 Non post-neonatally acquired CP
87% of surveillance programs collect information regarding aetiology of non post-neonatally acquired CP
cases. Many programs reported collected this ad hoc in free-text comments boxes. Many specific risk
factors were reported (Table 11).
11.2 Neonatally acquired CP
50% of surveillance programs are able to distinguish (some) neonatally acquired CP cases from other non
post-neonatally acquired CP cases. Most programs reported this is only possible if there is a recorded
known cause.

12. Birth defects
Total responders n= 24 programs
75% of surveillance programs collect information on birth defects. The majority of programs record
defects categorised by ICD-10 codes and/or free text.
The upper age limit for recognition of birth defects varied from at birth to no restriction (Table 12).
Table 12: Upper age limit for recognition of birth defects Programs reporting this limit (n)
Birth 1 4 years 2 5 years 5 6 years 1 7 years 1 No restriction 8
67% of programs reported that a birth defects surveillance program existed serving the same population
as their CP surveillance program; 7 programs had performed linkages with these programs.
13. Surveillance programs of other childhood impairments
Total responders n= 25 programs
Eight programs (32%) reported that surveillance programs of other childhood impairments serve the
same population as their CP surveillance program. For some, the CP surveillance program and other
childhood impairment(s) surveillance program(s) are combined.
Surveillance programs of the following impairments were reported: autism spectrum disorders (n=7);
intellectual disability (n=3); vision impairment (n=3); hearing impairment (n=2); epilepsy (n=1);
neuromuscular diseases (n=1).
20 of 64
13. Cerebral Imaging
Total responders n= 24 programs
All programs collect some cerebral imaging information, either:
a) whether imaging has been performed (n= 19, 79%), of which 63% (n=12) record where imaging
was performed), and/or;
b) clinical reports of imaging findings (n=13, 54%), and/or;
c) the original images (n=3, 13%).
96% (n=23) of programs collected data pertaining to cranial magnetic resonance imaging (MRI), 67%
(n=16) to cranial ultrasound and 54% (n=13) to cranial computer tomography (CT). The majority of groups
accepted imaging taken at any age.
13.1 Imaging classification system
Total responders n= 21 programs
Seven programs have not yet adopted an imaging classification system. Fourteen groups reported the imaging classification system used by their surveillance program (Table 13).
Seven programs classified imaging based on clinical reports of neuroimaging findings, 1 program classified
scans by re-reading original images, and 3 used a combination of reports and re-reading images. Imaging
was classified by more than one person for 7 programs, and usually by a single person for 3 programs.
Classifications were made by a broad range of medical professionals (radiologist, neuropaediatrican,
paediatric neurologist, neuroradiologist, paediatrician, paediatric neuroradiologist), other clinicians and
by surveillance program staff.

14. Multiple births
Total responders n=24 programs
Surveillance programs were asked to report whether they collect information on various items related to multiple births (Table 14). Table 14: Multiple births
Programs collecting this information n (%)
Plurality * 22 (92%) Birth order of child with CP 21 (88%) Death of a co-multiple < 20 weeks gestation 4 (17%) Death of a co-multiple > 20 weeks gestation 4 (17%) Timing of death of a co-multiple e.g. intrapartum, postpartum 3 (13%) Health outcome of siblings from this multiple birth 3 (13%) Zygosity 3 (13%) Chorionicity and amnionicity 2 (8%)
* One additional program recorded if the case was a singleton or from a multiple birth
14.1 Classification as a multiple birth
Total responders n=22 programs
73% (n=16) of respondents do not record a survivor as a multiple if their co-multiple(s) died before 20
weeks gestation.
15. Assisted conception
Total responders n=22 programs
55% (n=12) of surveillance programs recorded some aspect of assisted conception. Information collected
varies, with the majority collecting whether the case was an IVF pregnancy. Some surveillance programs
collect additional information including fertility drugs only, artificial insemination, ICSI, GIFT, other
assisted conception.
12 programs reported the standard practice in their region for number of embryos transferred during IVF.
Of these 10 reported single embryo transfer as standard, while one program reported 2 embryos
transferred as standard procedure. One program reported as few as possible, but that practice varies.
22 of 64
16. Associated impairments and co-occurring conditions
Total responders n=24 programs
Surveillance programs were asked to report on the data they collect regarding impairments associated
with CP. All programs (100%) collect gross motor function using the Gross Motor Function Classification
System. Various programs also report on walking ability using their own scale, and some use the
Functional Mobility Scale (FMS). The data collected on other impairments and co-occurring conditions
varied considerably between surveillance programs (Table 15). Communication scales developed by
surveillance programs included classifications such as no impairment/some impairment/non-verbal, or
more complex expressive language/receptive language classifications. 3 programs report collect data
about disabilities of siblings.

17. Follow-up after verification
Total responders n=24 programs
5 programs (21%) systematically completed follow-up of children, after the cases have been verified as
having CP. Age at follow-up and frequency varied widely, from annually, to at 5 years, 10 years, and/or at
15-17 years of age. Methods of data collection during follow-up included the use of medical/allied health
notes and reports, emails to families and multi-disciplinary clinical assessment.
Data items collected at follow-up included repetition of data items previously collected, in addition to
items including education, predicted adult accommodation needs, mental health, quality of life,
participation, and surgery.

18. Interventions received and secondary impairment prevention
Total responders n=25 programs
18 programs (72%) collected data on interventions received (Table 16).
Table 16: Interventions received Programs collecting this information (n)
Surgeries 14 Spasticity medications 12 Assistive devices (including orthotics, equipment) 12 Therapies 9
4 programs (16%) reported having a longitudinal follow-up program for secondary impairment

19. Data sheets
Data collection forms were available for 22 operating programs. Overall 38 items were collected by at
least half of the programs, with 10 collected by all programs. 6 of these items were collected in the same
way across programs. It was clear that there was considerable common ground regarding key data items,
but also considerable variation in additional data items and methods of collection (Table 17).

20. Research collaboration
All 25 programs reported an interest in collaborating with other surveillance programs. 12 programs (48%
of 25 responders) have had a linkage/collaborative relationship with other registers serving the same
denominator group for research purposes, for example perinatal data sets/newborn quality register,
regional and national death indexes, intervention services/health databases, birth defects registry, CP
follow-up program.
16 programs (67% of 24 responders) reported a linkage/collaborative relationship with similar CP
surveillance programs serving other denominator groups. Benefits of such relationships were reported to
be: possibility of international collaborative studies, including with stalwarts of CP research; allows
sufficiently powered analyses in studies where number of cases per birth cohort is relatively limited;
implement common research programs on CP/related subjects; brainstorming on difficult issues common
to both surveillance programs (e.g. progressive disorders, prevalence rates trends, classifications, brain
injury vs. post neonatal CP); input and knowledge from others, sharing concerns and good mental
stimulus. Challenges to collaborations included: obtaining adequate funding; harmonization and
comparability of data e.g. common definition, common inclusion/exclusion criteria; seeking common
ground and direction of research.
20 programs (80% of 25 responders) across all three geographical regions were able to send ad hoc, de-
identified data to be used in collaborative studies with appropriate ethical approval. Furthermore, one
closed program was also able to send such data. These programs are marked in Appendix 1.
8 programs (33%) had access to controls, using a variety of methods (Table 19).
Table 19: Access to controls
Programs reporting this method (n)
National health care registers 2 Sampling of birth certificates 2 Invited study participants 2 Via hospitals 1 Siblings of registrants 1 Regional perinatal data collection 1
NB. One program reported multiple methods of accessing controls.
52% of programs reported trends that they would like to discuss with other programs (an asterix indicates
items reported by more than one surveillance program).
Decrease in rate of CP in extremely preterm infants (GA 20-27 weeks)*
Rates of CP amongst Indigenous community (of Australia)
Overall decreasing prevalence of CP
Shifts in how CP is being classified (increasing importance of CP Description form to make data comparable longitudinally and across surveillance programs)
Trend towards milder forms of CP
Increased incidence of unilateral CP (slight decrease of bilateral)*
Increase in frequency of children diagnosed with hypotonic CP*
No change in survival
Burden of CP caused by congenital CMV infection
36 of 64
Rates of CP after introduction of cooling for HIE/NE, particularly regarding dyskinetic CP and function
Health and other issues facing young and aging adults
71% of programs reported having research questions that can only be answered, or would better be
answered, through collaboration with other surveillance programs. Such questions included (an asterix
indicates items reported by more than one surveillance program):
cCMV*
Multiple births, especially higher order* and advances in neonatal care and fertility management
Congenital anomalies*
CP prevalence by age of gestation, for aetiological purposes
Autism and CP
Birthweight and gestational age reflecting changes in CP prevalence and advances in neonatal care
Comparison of CP prevalence and characteristics among school-aged children*

Current research themes being investigated by the surveillance programs include aetiology (68%),
participation (48%), evaluation of interventions (40%) and survival (32%) (Table 20). Many groups
reported multiple research themes. Other themes reported include: pain, quality of life,
prevalence/characteristics of CP by race/ethnicity, methodological issues relating to estimating
prevalence including migration, feasibility of collecting and analysing neuroimaging findings, natural
history of communication development, development of functions, evaluation of instruments, neuro-
imaging, long term outcomes (social and health) including siblings and parents, secondary prevention
through active surveillance, health services research, epidemiology, mobility, transport, geography.

Vlatka Mejaski Bosnjak Children’s Hospital, University of Zagreb Klaiceva 15 Zagreb 10 000 Croatia [email protected]
Aims: The goal of the Canadian Cerebral Palsy Registry is to allow the sharing of data, thereby promoting research in this field. Specifically, the registry will: 1. Provide an epidemiologic profile of cerebral palsy in Canada reflecting the full heterogeneity of the disorder; 2. Provide a platform for population-based research on CP that promotes a greater understanding of the disorder from mechanistic to family and community perspectives; 3.Identify risk factors associated with cerebral palsy; 4. Serve to promote research into causal pathways, prevention and treatment of this disorder; 5. Facilitate additional research into CP by providing a platform for subject recruitment.
Aims: Croatian Register of Cerebral Palsy, sent data to SCPE- NET for the first time in 2012, for children born 2003. Five counties were involved (7543 live born) 23 children with CP were included, giving the prevalence 3.05/1000. In 2003 Croatia had 43 456 live born neonates. In 2013 9 counties were involved with 18 674 live born, 64 children with CP were identified, giving CP prevalence 3.42/1000. Data for children with CP born in 2005 are already sent to SCPE undergoing evaluation. A part of CP register Croatia has pilot register of children at neurorisk in county Zagreb, introduced in 2007, which provide early intervention and monitoring of children’s development as a secondary prevention of neurodevelopmental disabilities.

EUROPE
Danish National Cerebral Palsy Register * National Institute of Public Health Øster Farimagsgade 5.2 1399 Copenhagen Denmark
Surveillance of Cerebral Palsy in Europe (SCPE) * European Commission
Commenced: 1960 Commenced: 1998 Inclusion criteria: According to SCPE criteria reviewed by a neuroped reading case notes.
Inclusion criteria: The child has cerebral palsy. It was agreed that although age 5 years was the optimal age for confirmation of diagnosis, for practical reasons, cases would be included in the SCPE database if they fulfill the clinical criteria after their 4th birthday. It is recognised that some children with severe cerebral palsy are correctly diagnosed at a young age, but die before their 4th birthday. Exclusion of these children could result in under-estimates of the prevalence of the CP in Europe. Thus, children in whom a diagnosis of CP is made after the age of 2 years, but who die before this diagnosis can be reconfirmed are also notified to in the SCPE database. Similarly, children ‘lost to follow-up’ at age 5 but with unambiguous diagnosis of CP on or after the age of 3 years should also be submitted to SCPE database. No upper age limit of onset of cerebral palsy (in children with a postneonatal cause) has been identified.
Peter Uldall Rigshospitalet Neuroped clinic 5004 Blegdamsvej Copenhagen 2100 Denmark [email protected]
Christine Cans & Elodie Sellier SCPE CHU Grenoble 38000 France [email protected]
Aims: Monitoring birth-rate of CP in Denmark, exploring aetiology, long term follow-up on social and morbidity aspects in adulthood and monitoring intervention through merging with an active quality database (CPOP).
Aims: The aim of the SCPE network is to disseminate knowledge about cerebral palsy through epidemiological data, to develop best practice in monitoring trends in CP, and to raise standards of care for children with cerebral palsy. Most centres do not have sufficient numbers of cases of cerebral palsy to be able to provide reliable estimates of trends over time in prevalence rates or to have sufficient statistical power to study causes and health service questions. By pooling anonymous data from different registers, it is possible to undertake special analyses such as of cerebral palsy in very low birth weight babies.

Merseyside Cerebral Palsy Register The University of Liverpool
Northern Ireland Cerebral Palsy Register (NICPR) * Queen's University of Belfast
Commenced: 1980 Closed: 2009
Commenced: NICPR has been functioning since 1991 collecting information on children born in NI since 1977 or born elsewhere and moved in NI since 1992.
Inclusion criteria: Each child must fulfil the diagnostic criteria for either 'early' or 'late onset' CP. Early onset CP is defined as a collection of motor impairments affecting posture and movement, resulting in a loss of function and caused by a nonprogressive malformation or lesion to the developing brain sustained in early life (sometime before, during or soon after birth). 'Late onset' CP are those motor impairments arising from a nonprogressive malformation or lesion in the developing brain sustained sometime after the first 30 days of life but before the child's 5th birthday. These cases are sometimes referred to as 'postnatally acquired' CP. (ii) NICPR captures information on children with CP born in NI 1977 to date; or born elsewhere but moving into NI since 1992 (when the NICPR began) and pertains only to children (i.e. before their 16th birthday).

Appendix 4: Survey
Thank you for your interest in the 2nd International Survey of Cerebral Palsy Registers and Surveillance Programs. The original survey was completed in 2009, prior to the World CP Register Congress at the International Cerebral Palsy Conference in Sydney (February 2009). A survey report was also published in 2009 (http://www.cpresearch.org.au/pdfs/Reportoftheinternationalsurveyofcerebralpalsyregistersandsurveillancesystems2009.pdf). This study aims to provide an updated summary of the Cerebral Palsy (CP) registers and surveillance programs around the world. Please complete the survey on behalf of your individual register/surveillance program, NOT based on a minimum data set of a collaboration of registers that you may be part of e.g. SCPE, ACPR. The custodian of the collaboration will complete a survey for the collaboration. Please forward this survey to any new CP registers/surveillance programs that you are aware of. Results from this survey will be synthesised and disseminated at a preconference workshop at the American Academy of Cerebral Palsy and Developmental Medicine (AACPDM) Conference in San Diego USA, September 2014. We also aim to publish survey results in a new Developmental Medicine and Child Neurology journal supplement in 2015. By proceeding with this survey: a) I certify that I have permission to provide information on behalf of my register/surveillance program; b) I give permission for the information I provide to be included in a summary document which will be made available to participants in this survey and attendees at the 2014 AACPDM Cerebral Palsy Register preconference workshop; c) I give permission for the information I provide to be included in future publications in which both my name and my register/surveillance program will be included and acknowledged as a contributor, including a summary article in a Developmental Medicine and Child Neurology journal supplement in 2015.
