摘要

Objective: To investigate the predictors of minimal clinically important changes on outcome measures after robot-assisted therapy (RT).

Design: Observational cohort study.

Setting: Outpatient rehabilitation clinics.

Participants: A cohort of 55 outpatients with stroke.

Interventions: Patients with stroke received RT for 90 to 105 min/day, 5 days/week, for 4 weeks.

Main Outcome Measures: Outcome measures, including the Fugl-Meyer Assessment (FMA) and Motor Activity Log (MAL), were measured before and after the intervention. Potential predictors include age, sex, side of lesion, time since stroke onset, finger extension, the Box and Block Test (BBT) score, and the FMA distal score.

Results: The statistical analysis showed the BBT score (odds ratio, 1.06; P = 0.04) was a significant predictor of clinically important changes in the FMA. Female sex (odds ratio, 3.90; P = 0.05) and the BBT score (odds ratio, 1.07; P = 0.02) were the 2 significant predictors of clinically significant changes in the MAL amount of use subscale. The BBT score was the significant predictor of an increased probability of achieving clinically important changes in the MAL quality of movement subscale (odds ratio, 1.07; P = 0.02). The R² values for the 3 logistic regression models were low (0.114 to 0.272).

Conclusions: Our results revealed that patients with stroke who had greater manual dexterity measured by the BBT appear to have a higher probability of achieving clinically significant motor and functional outcomes after RT. Further studies are needed to evaluate other potential predictors to improve the models and validate the findings.
