RESUMO
BACKGROUND: Studies demonstrate the benefits of upper limbs cycle ergometer (ULCE) in subacute and chronic stroke subjects, but the literature still needs to explore the acute phase of the disease. OBJECTIVE: Verify the effects of ULCE on muscular strength, trunk control and independence of post-stroke subjects in hospital acute phase. METHODS: In this randomized clinical trial participants were allocated into two groups. The control group (CG) performed two daily sessions of conventional physiotherapy, while the intervention group (IG) had one daily session of conventional physiotherapy and one of ULCE. The interventions were carried out for 20 minutes for five days. Both groups were assessed before and after the treatment for upper limbs strength by manual dynamometer, trunk control by Trunk Impairment Scale and level of independence by the Modified Rankin Scale. RESULTS: Twenty subjects with mean ages of 63.5±4.5 were enrolled. There was a significant intra-group difference of palmar grip, shoulder abductors, elbow flexor and wrist extensor strength, trunk control and functional independence only in IG. Inter-group difference for all variables showed superiority in IG. CONCLUSIONS: ULCE is an effective device for increasing muscle strength, trunk control and consequently improving the independence of post-stroke subjects in the acute hospital phase.

BACKGROUND: Studies demonstrate the benefits of aerobic cycling training in subacute and chronic stroke subjects, but there is a lack in the literature about its effects on the acute phase. OBJECTIVE: Verify the effects of aerobic cycling training on lower limbs muscle strength, gait speed, balance, mobility and functionality of acute stroke subjects. METHODS: Control group (CG) performed conventional physiotherapy twice a day and the intervention group (IG) performed a conventional physiotherapy and a cycle ergometer session, for five consecutive days. Subjects were assessed for muscle strength by a digital dynamometer, gait speed by the 10-meter-walk-test, balance by the Berg Balance Scale, mobility by the ICU-Mobility-Scale and functionality by the Perme Score. RESULTS: Twenty subjects were enrolled in the study, 10 in the CG and 10 in the IG. Lower limbs muscle strength, the main endpoint, was better in the IG compared to the CG. The same was found in the secondary endpoints. The intragroup analysis was also positive for the CG in the mobility and functionality. CONCLUSIONS: Conventional physiotherapy combined with cycling exercise showed better results in the improvement of muscle strength of lower limbs, mobility and functionality of subjects who suffered from acute stroke.
