Wii Fit exergames have been less commonly used for the rehabilitation of athletes after Anterior Cruciate Ligament Reconstruction (ACLR). This study aims to investigate the effects of an expert system using Wii Fit exergames compared to conventional rehabilitation following ACLR. A forward-chaining rule-based expert system was developed which proposed a rehabilitation program that included the number and type of exercise in terms of difficulty and ease and the duration of each exercise in a progressive manner according to the patient's physical condition.
Twenty eligible athletes aged 20-30 who underwent ACLR were enrolled in this study and randomly assigned to two groups; and received 12 sessions of either Wii Fit exergames as Wii group (n = 10) or conventional rehabilitation as CL group (n = 10).
The main outcomes consisted of pain (Visual Analogue Scale (VAS)), knee effusion, knee flexion range (KFR), thigh girth (TG), single-leg hop for distance (SLHD), and for time (SLHT), static and dynamic balance tests. Both groups had considerable improvement in all outcomes, also there were significantly differences between Wii and CL groups as follows; VAS (P < 0.001), knee effusion (P < 0.001), TG (P = 0.001), KFR (P = 0.012), static balance in stable position (P < 0.001) and in unstable position (P = 0.001), dynamic balance in the anterior (P < 0.001), posteromedial (P < 0.001), posterolateral (P = 0.004) directions, symmetry index of SLHD (P < 0.001) and symmetry index of SLHT (P = 0.013).
The findings showed that using Wii Fit exergames in post-ACLR patients reduced pain and effusion while also improving function and balance significantly. Iranian Registry of Clinical Trials registration number is IRCT20191013045090N1, and the registration date is 03-03-2020.
Wii Fit 运动游戏在运动员前交叉韧带重建 (ACLR) 后较少用于康复。本研究旨在探讨使用 Wii Fit 运动游戏的专家系统与 ACLR 后的常规康复相比的效果。开发了一个正向链接基于规则的专家系统，该系统根据患者的身体状况，以渐进的方式提出了一个康复计划，包括根据难度和容易程度确定的运动次数和类型，以及每项运动的持续时间。
本研究纳入了 20 名年龄在 20-30 岁之间接受 ACLR 的合格运动员，他们被随机分为两组；并接受 12 次 Wii Fit 运动游戏（Wii 组，n = 10）或常规康复（CL 组，n = 10）。
主要结果包括疼痛（视觉模拟量表 (VAS)）、膝关节积液、膝关节屈曲范围 (KFR)、大腿围度 (TG)、单腿跳远距离 (SLHD) 和时间 (SLHT)、静态和动态平衡测试。两组在所有结果上都有显著改善，Wii 组和 CL 组之间也有显著差异；VAS（P < 0.001）、膝关节积液（P < 0.001）、TG（P = 0.001）、KFR（P = 0.012）、稳定位静态平衡（P < 0.001）和不稳定位静态平衡（P = 0.001）、前向（P < 0.001）、后内侧（P < 0.001）、后外侧（P = 0.004）动态平衡、SLHD 对称性指数（P < 0.001）和 SLHT 对称性指数（P = 0.013）。
研究结果表明，在 ACLR 后患者中使用 Wii Fit 运动游戏可减轻疼痛和积液，同时显著改善功能和平衡。伊朗临床试验注册中心注册号为 IRCT20191013045090N1，注册日期为 2020 年 3 月 3 日。
