Acute ankle sprains are usually managed functionally, with advice to undertake progressive weight-bearing and walking. Mechanical loading is an important modular of tissue repair; therefore, the clinical effectiveness of walking after ankle sprain may be dose dependent. The intensity, magnitude and duration of load associated with current functional treatments for ankle sprain are unclear.
To describe physical activity (PA) in the first week after ankle sprain and to compare results with a healthy control group.
Participants (16-65 years) with an acute ankle sprain were randomised into two groups (standard or exercise). Both groups were advised to apply ice and compression, and walk within the limits of pain. The exercise group undertook additional therapeutic exercises. PA was measured using an activPAL accelerometer, worn for 7 days after injury. Comparisons were made with a non-injured control group.
The standard group were significantly less active (1.2 ± 0.4 h activity/day; 5621 ± 2294 steps/day) than the exercise (1.7 ± 0 .7 h/day, p=0.04; 7886 ± 3075 steps/day, p=0.03) and non-injured control groups (1.7 ± 0.4 h/day, p=0.02; 8844 ± 2185 steps/day, p=0.002). Also, compared with the non-injured control group, the standard and exercise groups spent less time in moderate (38.3 ± 12.7 min/day vs 14.5 ± 11.4 min/day, p=0.001 and 22.5 ± 15.9 min/day, p=0.003) and high-intensity activity (4.1 ± 6.9 min/day vs 0.1 ± 0.1 min/day, p=0.001 and 0.62 ± 1.0 min/day p=0.005).
PA patterns are reduced in the first week after ankle sprain, which is partly ameliorated with addition of therapeutic exercises. This study represents the first step towards developing evidence-based walking prescription after acute ankle sprain.
急性踝关节扭伤通常采用功能治疗，建议逐渐负重和行走。机械加载是组织修复的重要模块；因此，踝关节扭伤后行走的临床效果可能与剂量有关。目前踝关节扭伤的功能治疗中与负荷相关的强度、幅度和持续时间尚不清楚。
描述踝关节扭伤后第一周的身体活动（PA）情况，并与健康对照组进行比较。
将 16-65 岁的急性踝关节扭伤患者随机分为两组（标准或运动组）。两组均建议冰敷和加压包扎，并在疼痛范围内行走。运动组还接受了额外的治疗性运动。使用 activPAL 加速度计在受伤后 7 天内测量 PA。将结果与未受伤的对照组进行比较。
标准组的活动量明显低于运动组（1.2 ± 0.4 小时/天；5621 ± 2294 步/天）（p=0.04；7886 ± 3075 步/天，p=0.03）和未受伤的对照组（1.7 ± 0.4 小时/天，p=0.02；8844 ± 2185 步/天，p=0.002）。此外，与未受伤的对照组相比，标准组和运动组在中度（38.3 ± 12.7 分钟/天 vs 14.5 ± 11.4 分钟/天，p=0.001 和 22.5 ± 15.9 分钟/天，p=0.003）和高强度活动（4.1 ± 6.9 分钟/天 vs 0.1 ± 0.1 分钟/天，p=0.001 和 0.62 ± 1.0 分钟/天，p=0.005）中的时间更少。
踝关节扭伤后第一周的 PA 模式减少，而加入治疗性运动后部分得到改善。本研究是朝着制定急性踝关节扭伤后行走处方的循证方法迈出的第一步。
