Recovery of impaired motor function of the upper extremity after stroke.
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 fit 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.
