Objective To investigate the perception of muscular effort in individuals with multiple sclerosis (MS) and healthy controls during dynamic contractions. Design Case-control study. Setting MS day care center. Participants Individuals with MS (n=28) and controls (n=28) (N=56). Interventions Not applicable. Main Outcome Measures Perceived muscular effort during dynamic elbow extensions was rated at 9 different weight intensities (10%90% of 1-repetition maximum) in a single-blind, randomized order using the OMNI-Resistance Exercise Scale. Muscle activity of the triceps brachii muscle (lateral head) was measured via surface electromyography and normalized to maximal voluntary excitation. Results According to OMNI-level ratings, significant main effects were found for the diagnostic condition (F=27.33, P<.001 indicating confidence interval lower mean omni-level ratings for ms and the intensity level p showing increased levels both groups. furthermore significant main effects were found diagnostic condition ci to higher maximal voluntary excitation values relative muscle activities increasing in> Conclusions Similar to controls, individuals with MS were able to differentiate between different intensities of weight during dynamic elbow extensions when provided in a single-blind, randomized order. Therefore, perceived muscular effort might be considered to control resistance training intensities in individuals with MS. However, training intensity for individuals with MS should be chosen at approximately 1 OMNI level lower than recommended, at least for dynamic elbow extension exercises. |
