Title: | Motor fatigability after low-intensity hand grip exercises in persons with multiple sclerosis | Authors: | SEVERIJNS, Deborah Lemmens, Mieke THOELEN, Ronald FEYS, Peter |
Issue Date: | 2016 | Publisher: | ELSEVIER SCI LTD | Source: | MULTIPLE SCLEROSIS AND RELATED DISORDERS, 10, p. 7-13 | Abstract: | Introduction: During maximal, sustained contractions, persons with multiple sclerosis (PwMS) show higher motor fatigability in comparison with healthy persons. It is not known if motor fatigability is also different between PwMS and healthy persons during low-intensity exercises. Thus, the aim of this study was to determine the difference in hand grip fatigability between healthy persons and PwMS for both hands during low-intensity hand grip exercises. Methods: 19 PwMS and 19 healthy controls performed 18 min of hand grip exercises at a maximum of 25% of the maximal voluntary strength, with an electronic hand dynamometer. Perceived fatigability, maximal hand grip strength and muscle activity (electromyography) of the wrist flexors and extensors were recorded in between these exercises for the dominant and non-dominant hand. Results and discussion: There was a significant decrease in maximal hand grip strength after exercising in both groups and for both hands, mainly situated in the first 6 min. In contrast to what was hypothesized, PwMS did not show more decline in strength than healthy controls, neither in the dominant nor the non dominant hand. There was no group difference in the increase of the perceived fatigability in the dominant hand. However, for the non-dominant hand, the perceived fatigability after exercising increased more in PwMS than in healthy controls. Additionally, there was no relation between fatigue indices, as assessed with short maximal contractions and the strength decline after low-intensity repetitive exercises. (C) 2016 Elsevier B.V.
