Effects of modified constraint-induced movement therapy on upper extremity function and occupational performance of stroke patients.
Jeong-Hui Kim, Moon-Young Chang
PMID 30154606WHAT IT FOUND
Adding modified constraint-induced movement therapy to standard rehab improved arm use and daily task performance in stroke patients.
The standard rehab group alone showed little change. With only 14 participants, these results are preliminary and require confirmation in larger trials.
Key findings
01The experimental group received modified constraint-induced movement therapy plus conventional rehabilitation, while the control group received only conventional rehabilitation.
02The modified constraint-induced movement therapy group showed significant improvements in the Manual Function Test, Motor Activity Log, and Canadian Occupational Performance Measure from before to after the intervention.
03The average change in the amount of motor use (MAL-A) was 37.71 ± 15.14 for the mCIMT group compared to 5.29 ± 2.50 for the control group.

What it does not show
The study included only 14 participants, making the results highly susceptible to random variation and not generalizable to the broader stroke population. The text does not describe the method of allocation to groups, so it is unclear if the study was truly randomized or how selection bias was controlled. The study did not report blinding of assessors or participants, which could introduce bias in subjective outcome measures like the Motor Activity Log and Canadian Occupational Performance Measure. The follow-up period was short, with intervention lasting only two weeks, so long-term effects are unknown.
Declared interests
The authors declare that there is no conflict of interest.
The easy way to misread this
Do not conclude that mCIMT is superior to conventional therapy for all stroke patients based on this study. The sample size was very small (14 patients), and the lack of detail on randomization and blinding means the observed differences could be due to chance or bias rather than the treatment effect.
