1. To develop the equipment which assesses the joint rangeof motion without any examiner contact with the bonylevers.

2. To assess the accuracy of NCCG by comparing withstandard goniometer.

OBJECTIVE

NEEDS OF THE STUDY

Measurement of the joint range of motion is important for therehabilitation professionals in assessing, diagnosing, determiningthe prognosis, and treating the physical impairments.

A number of measurement tools are available in the rehabilitation

set ups including the visual estimation, inclinometer, goniometer,motion analyzing system, computer aided motion analysisinstruments, and video based motion analysis system.

Goniometer is the most commonly used manual tool for the jointrange of motion assessment.

However it may influence the actual range available at the joint. For the first time the range of motion measurement by the non-

contact computerized method.

Cost effective

WHY ALTERNATIVE

Technical error for Universal Goniometer

Cost effective for motion analyzing system

Ttechnical expertise needed to operate instrument or interpret the

findings for isokinetic dynamometer Time consuming for photographic goniometer

The cumbersome method of using it for opto-electric motionanalyzing system

UNIVERSAL GONIOMETER

Universal goniometer consists of a fulcrum, a stationery arm, amovable arm, a circular scale imprinted around the fulcrum.

Both the arms are connected at the center of the fulcrum in such a

manner that when moving arm moves with respect to the stationeryarm, an acute angle is created between the central axes of both thearms.

The circular scale indicates the amount of motion at the joint in formof degrees, by recording the acute angle formed between both the

arms (moving and stationery arm).

ERRORS IN UNIVERSAL GONIOMETER

The examiner might influence the joint ranges by forceful flexion orextension or the measured joint, or also might obstruct the actualranges available at joint (Chiu et al, 1998).

Parallax error when the eye of the examiner are not completelyparallel to the scale line of the goniometer

Incorrect landmark identification

The failure to stabilize the anatomical landmarks and the arm of thegoniometer when the client is executing the movement

overlying skin which in case of heavy built patients may alter theposition of the bony landmark. (Bennett et al, 2009)

HYPOTHESIS

In the present study we hypothesize that development of a non-contact computerized version of goniometer (NCCG) is needed toenhance the accuracy, acceptability and user friendly mean ofassessing the joint range of motion, and to minimize the errorsassociated with its usage.

This project would also attempt to develop the cost effectiveinstrument and instantaneously result generating tool, so as toprovide the clinician a powerful assessment tool for enhancing theaccuracy of the determining prognosis or the treatment approach forthe rehabilitation of the joint disorders.

METHODOLOGY

Total 100 subjects will be enrolled for the study including 50 patients and 50normal with age group 20-40 years.

The Normal subjects will be free from the joint pathology while the patientgroup will have subjects suffering from the joint pathology including the jointrange restriction.

The subjects will be recruited from the outdoor patients (OPD).

Inclusion Criteria:

Age group 20-40 years

Either male or females

Exclusion Criteria:

History of the surgery on the, to be assessed limb

Neurological problems compromising the movement at the concerned joint

Spasticity, rigidity or the hypertonicity

Psychiatric condition
