Is High-intensity Aerobic Interval Training Appropriate for Recovering Impairments and Activity Limitations in the Acute Phase of Stroke? A Randomized Controlled Trial in Benin
Status: Recruiting
Location: See location...
Intervention Type: Other
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
This clinical trial aims to examine the effects of combining HIIT on a semi-recumbent cycle ergometer (HIIT-RCE) with conventional physiotherapy on impairments and activity limitations in early subacute stroke. We hypothesized that HIIT combined with conventional physiotherapy would be more effective than conventional physiotherapy in improving workload capacity.

⁃ People with the diagnosis of stroke were screened and recruited within the first-month after the stroke onset according to the following criteria
• first episode from an ischemic or hemorrhagic stroke confirmed by CT scan;
• muscle strength of the affected leg defined by Motricity Index between 14 and 19, i.e., between 2 and 4 on the Medical Research Council scale;
• modified Ashworth score of 0 or 1, indicating no spasticity or slight spasticity over the affected lower limb, respectively
• able to walk at least 5 meters independently with or without assistive devices and understand simple instructions;
• resident in Parakou or its surroundings
• wish to participate in the hospital program

Treatments
Experimental: HIIT-RCE
All participants will receive conventional physiotherapy for half an hour thrice weekly for six weeks. Conventional physiotherapy will be followed by a 15 min rest period, then the HIIT on a semi-recumbent cycle SOLE R92 (HIIT-RCE) will be performed.Each HIIT-RCE session will be preceded by 3-min of unloaded cycling as a warm-up and ended with 3-min of stretching. The HIIT-RCE procedure will start at 4-min at 30% of the peak workload interspersed with 1-min at 70% of the peak workload for weeks 1-2 (4 repetitions for 20 min) and increased by approximately 5 minutes every two weeks as tolerated to reach 30 minutes from week 5 (6 repetitions). The training intensity will progress similarly by 5% peak work rate two weeks as tolerated to reach 4-min at 40% peak workload interspersed with 1-min 80% peak workload from week-5. The cycle frequency will be at least 50 rpm.
Active_comparator: Conventional physiotherapy
The group will receive conventional physiotherapy that will consist primarily of passive movement, stretching, balance training, strengthening, and lower intensity overground walking for 30 minutes. This will be followed by a 15-minute rest period. Then an unloaded cycling session on a semi-recumbent cycle ergometer with preferred cadence until to get equal energy expenditure per session between groups by case-matching.
