Introduction Most stroke patients suffer from neurological or musculoskeletal conditions involving hand disabilities. Post stroke rehabilitation is an important part of restoring lost abilities in the hand function and testing for progress and performance on an ongoing basis is performed ongoing manually by a therapist. For this purpose a validated and reliable objective test is used. Most of these tests involve measuring the time it takes to complete a set of activities, which is crafted to match a set of common daily activities. The testing is costly to the health care system, and makes the patient reliant on therapist assistance and more inexpensive methods of testing are needed. Methods The trial included eleven healthy subjects, 4 women, 7 men, 20 -30 years of age. All subjects completed the 3 subtests of the Modified Jepson Taylor Hand Function Test, and time was measured during all tests, by a therapist and by a Microsoft kinect camera. Result The measurements in subtest 2 showed no indication of any overall systematic discrepancies between the manual assessments and the automatic assessments. For the measurements in subtest 4 there was an indication of a systematic difference, between the two measurement methods. For the measurements in subtest 5 there was an indication of systematic difference between the two measurements methods The duration of the time in seconds, which it took for the 11 participants, to perform the subtests of the MJT was recorded automatically and manually and compared with a Bland Altman plot fir each subtest.
Conclusion This study managed to show that the automated MJT works, and that it was possible to retrieve useful measurements and pictures from the Kinect Camera. Some differences were found between the two measuring methods and the automated measurement in subtest 4,that showed shorter times than the manual measurement, while the opposite was found in the measurement for subtest 5. All time differences between the methods were within 1.1 sec however and if put in perspective of the average time, it took to perform each of the three subtests subtest 2 (0.50 sec), subtest 4(1.1 sec.) and subtest 5 (0.60 sec.) it is considered an acceptable error. Therefore this study concludes that the automated test is as useful, as the manual test, and that the automated MJT test, can measure time just as well as the manual MJT.
