EVALUATING MOTOR RECOVERY EARLY AFTER STROKE - COMPARISON OF THE FUGL-MEYER ASSESSMENT AND THE MOTOR-ASSESSMENT SCALE

This study compared the measurements of the Motor Assessment Scale (MA S) to that of the Fugl-Meyer Assessment (FMA), a reliable and valid te st for motor function in stroke patients. Thirty-two patients (20 men, 12 women) with a mean age of 60 years, and a mean time since stroke o f 64.5 days, were tested with the FMA and MAS on two consecutive days. The Spearman correlation coefficient for total FMA and total MAS scor es was 0.96. For selected items, significant (p < 0.001) correlations ranged from 0.65 to 0.93, except for sitting balance (-0.10). Low nega tive correlations between sitting balance scores and other items (moto r and sensation) were found only for the FMA test, suggesting that the FMA sitting balance test is not valid for measuring balance and is li kely responsible for the low correlation. Comparison of scores (normal ized in percent of maximal value) for corresponding items of the two i nstruments also indicated that the FMA measured a higher (Wilcoxon = p < 0.0001) level of motor recovery, (especially in more disabled patie nts), for both the upper (15.7%) and lower extremities (27.5%). Lastly , a cumulative frequency distribution analysis indicated that a larger proportion of patients was found in the lower class interval scores o f the MAS in comparison to the FMA. These results (1) support the conc urrent validity of the MAS for measuring motor recovery in acute strok e patients; (2) demonstrate the poor validity of the FMA sitting balan ce test, and (3) suggest that the FMA scale can better discriminate th e level of motor recovery than the MAS in the early stage of recovery or in the more disabled subjects.
