Summary
Functional rehabilitation improved motor function and daily living activities in stroke survivors more than nonfunctional strategies. Both methods altered brain activity patterns, but functional approaches showed broader clinical benefits.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
- Clinical Neurology
Background:
- Stroke survivors often undergo motor rehabilitation using functional (FS) or nonfunctional (NFS) strategies.
- Comparing the efficacy of these strategies is crucial for optimizing recovery.
Purpose of the Study:
- To compare the effects of functional versus nonfunctional motor rehabilitation strategies in chronic stroke survivors.
- To assess clinical outcomes and neuroimaging changes using functional Magnetic Resonance Imaging (fMRI).
Main Methods:
- Twelve chronic stroke patients with hemiparesis were randomly assigned to FS or NFS rehabilitation.
- Clinical assessments (Fugl-Meyer, ARA, Barthel) and fMRI were conducted pre-rehabilitation and at multiple follow-up points.
- fMRI analyzed brain activation patterns, including M1 and SMA activity, and Lateralization Indexes.
Main Results:
- The NFS group showed isolated Fugl-Meyer score improvements.
- The FS group demonstrated significant improvements in Fugl-Meyer, ARA, and Barthel scores.
- fMRI revealed shared changes in both groups, including reduced activation sparseness and altered M1/SMA activity, with increased M1 asymmetry in the FS group.
Conclusions:
- Functional rehabilitation yielded broader clinical benefits than nonfunctional strategies for stroke survivors.
- Both strategies induced neuroplastic changes, but functional approaches were associated with more comprehensive motor and functional recovery.
