Predicting recovery following muscle injury can be difficult because it involves consideration of multiple factors. Our objective was to determine if psychological factors, sex, and peak pain and disability ratings could be predictive of delayed recovery following induced muscle injury. Healthy untrained volunteers (n=126; M:F 51:75) underwent a concentric/eccentric isokinetic exercise protocol on their dominant shoulder to induce fatigue, with individuals who reported pain (>0/10) at 96 h being classified as "not recovered". Individuals experiencing pain at 48 h were more likely not to be recovered (O.R.=1.62, p<0.001). Additionally, individuals with higher scores in pain catastrophizing at 48 h were more likely to experience pain at 96 h (O.R.=1.06, p<0.001). Pain duration (in days) was associated with pain scores at 48 h (β=0.385, p<0.001) and baseline anxiety (β=0.220, p=0.007). Fear of movement/re-injury at 96 h was found to be associated with pain catastrophizing at 48 h (β=0.537, p<0.001) and baseline levels of fear of pain (β=0.217, p=0.004). This study provides preliminary evidence that higher pain levels and pain catastrophizing following acute muscle injury are associated with poor recovery, higher fear of movement/re-injury and longer pain duration.
预测肌肉损伤后的恢复情况可能较为困难，因为这涉及到多个因素的考虑。我们的目的是确定心理因素、性别以及峰值疼痛和残疾评分是否可以预测肌肉损伤后的延迟恢复。健康的未训练志愿者（n=126；51 名男性，75 名女性）在其优势肩部进行等长/向心等速运动方案，以引起疲劳，报告 96 小时后出现疼痛（>0/10）的个体被归类为“未恢复”。在 48 小时时出现疼痛的个体更不可能恢复（OR=1.62，p<0.001）。此外，在 48 小时时疼痛灾难化得分较高的个体更有可能在 96 小时时出现疼痛（OR=1.06，p<0.001）。疼痛持续时间（天数）与 48 小时时的疼痛评分（β=0.385，p<0.001）和基线焦虑（β=0.220，p=0.007）相关。在 96 小时时发现运动恐惧/再损伤与 48 小时时的疼痛灾难化（β=0.537，p<0.001）和基线疼痛恐惧（β=0.217，p=0.004）相关。这项研究提供了初步证据，表明急性肌肉损伤后更高的疼痛水平和疼痛灾难化与恢复不良、更高的运动恐惧/再损伤以及更长的疼痛持续时间有关。
