Abstract
NAKAMURA, R., MORIYAMA, S., YAMADA, Y. and SEKI, K. Recovery of Impaired Motor Function of the Upper Extremity after Stroke. Tohoku J. Exp. Med., 1992, 168 (1), 11-20-Manual function score (MFS) of 174 hemiparesic 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.-arm function; hemiparesis; manual function test; prediction of recovery; stroke
