Summary
Robotic tilt-table training with or without functional electrical stimulation (FES) is safe for early stroke rehabilitation. These robotic interventions improved leg strength and cerebral blood flow compared to conventional tilt-table therapy alone.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Biomedical Engineering
Background:
- Stroke commonly results in hemiparesis, necessitating early rehabilitation for optimal recovery.
- Orthostatic reactions can limit early rehabilitation efforts.
- Robotic systems and functional electrical stimulation (FES) show potential to mitigate orthostatic intolerance during early training.
Purpose of the Study:
- To compare the safety and feasibility of robotic tilt-table training with (ROBO-FES) and without (ROBO) FES against conventional tilt-table training (control).
- To conduct a preliminary assessment of the efficacy of these interventions on leg strength and cerebral blood flow.
Main Methods:
- A controlled convenience sample study involving 104 hemiparetic ischemic stroke survivors (mean 4.6 days post-stroke).
- Participants were assigned to 30 days of ROBO-FES (n=38), ROBO (n=35), or control (n=31) groups, receiving conventional physical therapy.
- Safety and feasibility were assessed via adverse events and orthostatic reactions. Efficacy measures included impedance cardiography, transcranial doppler sonography (TCD), and the Medical Research Council (MRC) strength scale.
Main Results:
- No serious adverse events were reported; 8 control patients discontinued due to orthostatic reactions.
- Robotic interventions showed minimal blood pressure and cerebral blood flow velocity (CBFV) dips (<10%), unlike the control group (≥20% MAP decrease in 52%).
- ROBO-FES and ROBO groups demonstrated significantly greater improvements in leg strength (MRC scale) and CBFV compared to the control group (P < 0.05).
Conclusions:
- Robotic tilt-table exercise, with or without FES, is a safe and feasible early rehabilitation strategy for stroke survivors.
- These robotic interventions may enhance leg strength and improve cerebral blood flow more effectively than traditional tilt-table therapy.
- The findings support the potential of advanced robotic technologies in mitigating early post-stroke complications and improving functional outcomes.
