ABSTRACT

Motor learning is a relatively permanent change in motor performance. Also, one of the factors that can affect movement acquisition and movement patterns is pain and injury. The present study aims to investigate the effect of the induced local and remote pain during dart-throwing skill acquisition by examining motor skill accuracy and coordination variability. Three groups of 30 participants with a mean age of 18–25 were randomly assigned to local and remote pain or control groups. Capsaicin gel was applied to the pain groups for measuring the severity of pain using the Visual Analogue Scale (VAS). The results revealed that pain had no impact on dart-throwing skill acquisition, and there was no significant difference (p = 0.732) among the three groups at three stages of retention test. The results also showed that there was a significant difference among the three groups in terms of variability in shoulder-elbow (p = 0.025) and elbow-wrist joints (p = 0.000) in the deceleration and dart-throwing phases. The Central Nervous System seems to make adjustments when the task is associated with pain during the acquisition phase. Also, the groups with or without pain have notably various strategies, so differently, to perceive motor skills.

摘要

运动学习是运动表现的相对永久的变化。此外，可能影响运动获取和运动模式的因素之一是疼痛和损伤。本研究旨在通过检查运动技能准确性和协调变异性来研究在飞镖技能习得过程中诱发的局部和远程疼痛的影响。三组平均年龄为 18-25 岁的 30 名参与者被随机分配到局部和远程疼痛组或对照组。将辣椒素凝胶应用于疼痛组，以使用视觉模拟量表 (VAS) 测量疼痛的严重程度。结果显示，疼痛对飞镖技能的习得没有影响，并且在三个阶段的保留测试中，三组之间没有显着差异（p = 0.732）。结果还表明，三组之间在减速和投掷飞镖阶段的肩肘（p = 0.025）和肘腕关节（p = 0.000）的变异性方面存在显着差异。当任务与习得阶段的疼痛相关时，中枢神经系统似乎会做出调整。此外，有或没有疼痛的组有明显不同的策略，因此不同，以感知运动技能。
