One-legged bicycling as an assessment tool for patients with stroke
SUNNERHAGEN KS; MATTSSON K
ACTA NEUROL SCAND , 2005, vol. 111, n° 6, p. 373-378 Doc n°: 119668 Localisation : Documentation IRR Descripteurs : AF21 - ACCIDENTS VASCULAIRES CEREBRAUX, NB2 - PRATIQUE du SPORT et HANDICAP Objective - To assess whether one-legged bicycling correlates with muscle strength and thereby could work as an outcome measure for persons with stroke. Methods - The study comprised 29 men (age 35-65) with a first occurrence of stroke 6-35 months earlier. Each leg was evaluated separately. A ramp protocol was used (10 W/min), with continuous recording of the ventilatory uptake (Vo(2)) and heart rate. An isokinetic dynamometer was used to assess strength and endurance. Enzyme assays were performed on muscle biopsy samples. Results - The peak isometric strength and isokinetic strength of the paretic leg correlated with the max. W on the bicycle. The oxidative enzyme citrate synthase correlated with the workload for both legs on the bicycle and lactate dehydrogenase correlated with peak isometric strength in both legs. Conclusions - The one-legged bicycle exercise test can be used to assess endurance in persons with a previous stroke as it correlates with dynamometer testing and muscle biopsies.
