Objectives: A patient with poststroke hemiparesis learns to use the nonparetic arm to compensate for the weakness of the paretic arm to achieve independence in dressing. This is the learning process of new component actions on dressing. The purpose of this study was to develop the Upper-Body Dressing Scale (UBDS) for buttoned shirt dressing, which evaluates the component actions of upper-body dressing, and to provide preliminary data on internal consistency of the UBDS, as well as its reproducibility, validity, and sensitivity to clinical change., Design: Correlational study of concurrent validity and reliability in which 63 consecutive stroke patients were enrolled in the study and were assessed repeatedly by the UBDS and the dressing item of Functional Independent Measure (FIM)., Results: Fifty-one patients completed the 3-wk study. The Cronbach's coefficient alpha of UBDS was 0.88. The principal component analysis extracted two components, which explained 62.3% of total variance. All items of the scale had high loading on the first component (0.65-0.83). Actions on the paralytic side were the positive loadings and actions on the healthy side were the negative loadings on the second component. Intraclass correlation coefficient was 0.87. The level of correlation between UBDS score and FIM dressing item scores was -0.72. Logistic regression analysis showed that only the score of UBDS on the first day of evaluation was a significant independent predictor of dressing ability (odds ratio, 0.82; 95% confidence interval, 0.71-0.95). The UBDS scores for paralytic hand passed into the sleeve, sleeve pulled up beyond the elbow joint, and sleeve pulled up beyond the shoulder joint were worse than the score for the other components of the task. These component actions had positive loading on the second component, which was identified by the principal component analysis., Conclusions: The UBDS has good internal consistency, reproducibility, validity, and sensitivity to clinical changes of patients with poststroke hemiparesis. This detailed UBDS assessment enables us to document the most difficult stages in dressing and to assess motor and process skills for independence of dressing.

Objective: To identify predictors of the recovery of independent dressing ability after stroke., Design: Prospective cohort study., Setting: Rehabilitation unit at a university hospital., Participants: Sixty-three consecutive stroke patients were enrolled in the study. Twelve patients were not able to complete the study because they were discharged or transferred to another hospital before study completion., Intervention: Fifty-one patients underwent and completed 15 days of dressing training based on the time-delay method, which included the 10 component actions of upper-body dressing and 4 cues given by therapists., Main Outcome Measures: The dressing item of the FIM instrument, Brunnstrom motor recovery stages, presence or absence of deep and tactile sensation, Rey-Osterrieth complex figure test, Kohs block design test, body image test, Weintraub cancellation task, and presence or absence of the visual extinction phenomenon and the motor impersistence phenomenon., Results: The FIM upper-body dressing item score and the cancellation task score at the start of training were significantly better in patients who achieved independence in dressing within 15 training days than in patients who did not (P < .05). The motor impersistence phenomenon was found less frequently among patients who achieved independence in upper-body dressing than among patients who did not (P < .05). However, logistic regression analysis showed that only the FIM score for upper-body dressing on the first day of training was a significant independent predictor of dressing ability at the end of training (odds ratio, 4.33; 95% confidence interval, 1.51-12.37). The receiver operating characteristic curve indicated that a cutoff score of 3 would provide the best balance between sensitivity and specificity for the FIM upper-body dressing item. The positive predictive value of this cutoff score was .90, and the negative predictive value was .70., Conclusions: Our findings indicate that the FIM upper-body dressing score on the first day of dressing training is an independent predictor of recovery of upper-body dressing ability after stroke.
