Robotic upper limb therapy using multiple devices showed similar functional recovery to conventional therapy after stroke. Both treatments improved motor function, with robotic therapy showing a slight advantage in the Motricity Index.
Area of Science:
- Neurorehabilitation
- Robotics in Medicine
- Stroke Recovery
Background:
- Upper limb deficits persist in 30-60% of stroke survivors.
- Conventional therapy is the standard, but robotic therapy research often uses single devices.
- Evaluating multi-device robotic therapy for upper limb recovery is crucial.
Purpose of the Study:
- To compare the efficacy of multi-device robotic upper limb therapy against conventional therapy.
- To assess functional recovery and motor improvements in subacute stroke patients.
Main Methods:
- A multicenter randomized controlled trial involving 247 subacute stroke patients.
- Patients received either 30 sessions of multi-device robotic therapy or conventional therapy.
- Evaluations included Fugl-Meyer Assessment (FMA) and Motricity Index pre- and post-treatment, with 3-month follow-up.
Main Results:
- No significant difference in FMA score improvement between robotic and conventional therapy groups (mean difference -0.08, P=0.948).
- Both groups showed similar improvements in secondary measures, except for the Motricity Index, which favored the robotic group (adjusted mean difference 4.42, P=0.037).
- Improvements continued at 3-month follow-up with no between-group differences.
Conclusions:
- Multi-device robotic therapy is as effective as conventional therapy for improving upper limb function, activities, and participation in subacute stroke.
- Robotic therapy may offer specific benefits for motor function as indicated by the Motricity Index.
- Further research can explore the optimal integration of robotic devices in stroke rehabilitation.
