Hand Motor Fatigability Induced by a Simple Isometric Task in Spinal Cord Injury. J Clin Med. 2022 Aug 30;11(17):5108.2077-0383http://hdl.handle.net/2183/31728[Abstract] This study aimed: (1) to evaluate the hand motor fatigability in people with spinal cord injury (SCI) and compare it with measurements obtained form an able-bodied population; (2) to compare the hand motor fatigability in people with tetraplegia and in people with paraplegia; and (3) to analyse if motor fatigability is different in people with SCI with and without clinical significant perceived fatigability. Materials and methods: 96 participants with SCI (40 cervical and 56 thoracolumbar) and 63 able-bodied controls performed a simple hand isometric task to assess motor fatigability. The Fatigue Severity Scale was used for perceived fatigability evaluation. Results: The main results of this study can be summarized as follows: (1) the waning in muscle force (motor fatigability) during a fatiguing task is similar in controls and participants with SCI; (2) the motor fatigability is influenced by the maximal muscle force (measured at the beginning of the task); and (3) the perceived fatigability and the motor fatigability are largely independent in the individuals with SCI. Conclusion: Our findings suggest that the capability to maintain a prolonged effort is preserved in SCI, and this capacity depends on the residual maximal muscle force in people with SCI.engCreative Commons Attribution 4.0 International License 4.0 (CC-BY 4.0)http://creativecommons.org/licenses/by/4.0/FatigueFatigue severity scaleHumanIsometric contractionsSpinal cord injuryjournal articleopen access
