Objectives To compare the reciprocal control of agonist and antagonist muscles in individuals with and without spinocerebellar ataxia (SCA) and to evaluate the effect of a 4-week leg cycling regimen on functional coordination and reciprocal control of agonist and antagonist muscles in patients with SCA. Design Randomized controlled trial with repeated measures. Setting Research laboratory in a general hospital. Participants Individuals with SCA (n=20) and without SCA (n=20). Interventions A single 15-minute session of leg cycling and a 4-week cycling regimen. Main Outcome Measures Individuals with SCA (n=20) and without SCA (n=20) underwent disynaptic reciprocal inhibition and D1 inhibition tests of the soleus muscles before and after a single 15-minute cycling session. Individuals with SCA were randomly assigned to either participate in 4 weeks of cycling training (n=10) or to receive no training (n=10). The disynaptic reciprocal inhibition and D1 inhibition and International Cooperative Ataxia Rating Scale (ICARS) scores were evaluated in both groups after 4 weeks. Results Individuals with SCA showed abnormally strong resting values of disynaptic reciprocal inhibition and D1 inhibition (P<.001 and impaired inhibition modulation capacity after a single session of cycling the was restored icars scores improved significantly post: p=".046)" weeks training.> Conclusions A 4-week cycling regimen can normalize the modulation of reciprocal inhibition and functional performance in individuals with SCA. These findings are applicable to the coordination training of patients. |
