A pilot clinical trial on a Variable Automated Speed and Sensing Treadmill (VASST) for hemiparetic gait rehabilitation in stroke patients

Introduction Impairments in walking speed and quantity are common mobility-related problems after stroke. Treadmill training is a useful and accepted method to improve endurance and gait speed. Standard treadmills currently lack variable training speed and automated safe speed progression, thus risk...

description Introduction Impairments in walking speed and quantity are common mobility-related problems after stroke. Treadmill training is a useful and accepted method to improve endurance and gait speed. Standard treadmills currently lack variable training speed and automated safe speed progression, thus risking backward displacement and falls. A Variable Automated Speed and Sensing Treadmill (VASST) was thus developed and tested on chronic stroke subjects in a supervised exercise programme. Materials and MethodsAn open label study with assessor blinding was conducted in 10 community-dwelling chronic hemiplegics who could ambulate at least 0.1m/s for >150 meters with contact guard or supervision. Interventions included physiotherapist-supervised training on VASST for 60 minutes 3 times per week for 4 weeks (total 12 hours). Outcome measures of gait speed, quantity, balance and adverse events were assessed at 0, 2, 4 and 8 weeks.Results Altogether 10 subjects (8 males, mean age 55.5 years, 2.1 years poststroke) completed VASST training. Mean 10-meter walk test speed was 0.69m/s (SD 0.29) and mean 6-minute walk test distance was 178.3m (84.0). After 4 weeks of training, 70% had significant positive gains in gait speed (0.06 m/s SD 0.08m/s, P =0.037); and 90% improved in walking distance. (54.3m, SD 30.9m, P = 0.005). Both gains maintained at week 8. (0.12 m/s SD 0.1, P = 0.01; 56.0m, SD 31.8, P = 0.005). There were no adverse events.Discussion and conclusion This preliminary study demonstrates the initial feasibility and short-term efficacy of VASST for walking speed and distance for chronic stroke with hemiplegia.
