RECOVERY OF IMPAIRED MOTOR FUNCTION OF THE UPPER EXTREMITY AFTER STROKE.
Nakamura R, Moriyama S, Morita I (National Rehabilitation Center for the Disabled, Tokorozawa, Japan)
Manual function score (MFS) of 174 hemiparetic stroke patients was examined every week for 8 weeks after starting the occupational therapy with programs based on MFS recovery profile, and the relation between the time since stroke onset (x) and MFS (y) was approximated by a hyperbolic function, y=A-B/X. The patients were classified into two groups, 125 cases (71.8 %) with statistically significant tit of the function (fit group) and 49 without fit (non-fit). Using demographic and neurological variables of each patient, characteristics of the patients with regular recovery were analyzed. The results indicated that the gain of MFS during 8 weeks of the therapy was large in the fit group compared to the non-fit, and the regular recovery could be mostly expected in rather young patients, those with early start of the therapy, and those without ataxia, mental deterioration, and cortical lesions.

SURVEY OF TASKS USED IN THE PROGRAM BASED ON MANUAL FUNCTION SCORE (MFS) RECOVERY PROFILE IN STROKE PATIENTS.
Moriyama S, Morita I, Nakamura R (National Rehabilitation Center for the Disabled, Tokorozawa, Japan)
Manual function test was developed in an attempt to assess the impaired motor function of the affected upper extremity of stroke patients and to make statistical analysis of recovery process possible during rehabilitation. The test is composed of 32 subtests which examine the followings; arm motions (four tasks), grasping (two tasks) and manipulation (two tasks). The score referred to as manual function score (MFS) is ranging from 0 to 100. Our previous studies indicated that successive changes of MFS followed a predictable pattern in most patients, and the relation between time since stroke onset and MFS was approximated by a hyperbolic function. In this study we examined retrospectively the relation between tasks used to promote the functional recovery and MFS in 48 patients with regular recovery of MFS. The tasks were divided into two groups, one performed with arm movements (A) and the other with finger dexterity (B). Group A consisted with six activities of the affected arm. Tasks tot patients with low MFS were mainly performed by the shoulder and elbow movements (e.g., sanding). Tasks for those with high MFS were done by the arm and hand movements (e.g., moving wooden-block). Tasks of group B were handicrafts which were classified into three classes. In class I tasks the affected arm was used only to hold an object (e.g., lacing), in class 2 tasks the arms were used for simple repetitive motion (e.g., sawing), and in class 3 tasks the arms were used for bilateral simultaneous motions (e.g., handloom weaving). Patients with low MFS received class 1 tasks, and high MFS did mostly class 3 tasks.
