VR康复治疗对中风患者肢体功能有帮助，沉浸式效果更优。
Computer-mediated therapies for stroke rehabilitation: a systematic review and meta-Analysis
- 对比传统疗法，沉浸式VR更利于上肢功能恢复
- 18项研究显示非沉浸式VR与传统疗法效果相当
- 适合康复医学研究者和临床医生参考
目的：评估不同形式的虚拟现实（VR）治疗——沉浸式虚拟现实（IVR）和非沉浸式虚拟现实（NIVR）——相比传统疗法（CT），在改善中风患者躯体与心理状态方面的有效性。方法：在七个数据库中进行文献检索，包括ACM Digital Library、Medline（通过PubMed）、Cochrane、IEEE Xplore、Web of Science和Scopus。采用Cohen's d计算主要结局的效果量，使用随机效应模型汇总结果以获得总体治疗效应估计。结果：共纳入22项随机对照试验。3项研究显示IVR在上肢活动、功能及日常生活能力方面效果与CT相当；18项研究显示NIVR在上肢活动与功能、平衡与移动性、日常生活活动及参与度方面与CT效果相似。对比不同形式的VR发现，IVR可能在上肢训练和日常生活活动中优于NIVR。结论：本研究发现IVR治疗可能比NIVR更有效，但不优于传统疗法，可改善上肢活动、功能及日常生活能力。然而，尚无证据表明IVR疗效具有持久性。需要更大样本的研究来评估沉浸式虚拟现实技术的长期效果与潜在优势。
原文摘要 · Abstract (English)
OBJECTIVE: To evaluate the efficacy of different forms of virtual reality (VR) treatments as either immersive virtual reality (IVR) or non-immersive virtual reality (NIVR) in comparison to conventional therapy (CT) in improving physical and psychological status among stroke patients. METHODS: The literature search was conducted on seven databases. ACM Digital Library, Medline (via PubMed), Cochrane, IEEE Xplore, Web of Science, and Scopus. The effect sizes of the main outcomes were calculated using Cohen's d. Pooled results were used to present an overall estimate of the treatment effect using a random-effects model. RESULTS: A total of 22 randomized controlled trials were evaluated. 3 trials demonstrated that immersive virtual reality improved upper limb activity, function and activity of daily life in a way comparable to CT. 18 trials showed that NIVR had similar benefits to CT for upper limb activity and function, balance and mobility, activities of daily living and participation. A comparison between the different forms of VR showed that IVR may be more beneficial than NIVR for upper limb training and activities of daily life. CONCLUSIONS: This study found out that IVR therapies may be more effective than NIVR but not CT to improve upper limb activity, function, and daily life activities. However, there is no evidence of the durability of IVR treatment. More research involving studies with larger samples is needed to assess the long-term effects and promising benefits of immersive virtual reality technology.
