Objective

We performed a systematic review to investigate the effects of low-level laser therapy (LLLT) on pain and disability in patients with plantar fasciitis (PF).

Methods

We searched Pubmed, PEDro database, Scielo, and Cochrane Central for randomized controlled trials that evaluated the effects of LLLT for patients with PF. The methodological aspects of the studies included were scored using the PEDro scale. Three comparisons were made: LLLT compared with placebo, LLLT combined with conventional rehabilitation (CR) compared with CR and LLLT compared with extracorporeal shock wave therapy.

Results

Fourteen studies (817 patients) met the study criteria. Compared to the placebo group, LLLT improved pain (MD, −2.3; 95% CI: 2.6 to −2, I² = 0%; 4 studies, N = 234: moderate-quality evidence) in the short term (0–6 weeks). No significant difference in short-term disability was found for participants in the LLLT group compared to the placebo group. Compared to the CR group, LLLT combined with CR improved pain (MD, −2.0; 95% CI: 2.9 to −1.1, I² = 0%; 2 studies, N = 90: moderate-quality evidence) in the short term (0–6 weeks). Compared to extracorporeal shock wave therapy, LLLT did not significantly reduce pain intensity in the short term (MD, 0.5; 95% CI: 2.0 to 2.9, I² = 96%; 4 studies, N = 175: low-quality evidence).

Conclusions

LLLT may improve pain in the short term and can be considered as a component of care of patients with PF. However, this superiority disappeared compared to extracorporeal shock wave therapy.

低强度激光治疗对足底筋膜炎患者疼痛和残疾的影响：系统评价和荟萃分析

客观的

我们进行了一项系统评价，以研究低强度激光治疗 (LLLT) 对足底筋膜炎 (PF) 患者疼痛和残疾的影响。

方法

我们在 Pubmed、PEDro 数据库、Scielo 和 Cochrane Central 中搜索了评估 LLLT 对 PF 患者影响的随机对照试验。纳入研究的方法学方面使用 PEDro 量表进行评分。进行了三项比较：LLLT 与安慰剂比较，LLLT 联合常规康复 (CR) 与 CR 比较，以及 LLLT 与体外冲击波疗法比较。

结果

十四项研究（817 名患者）符合研究标准。^{与安慰剂组}相比，LLLT 在短期（0-6周）。与安慰剂组相比，LLLT 组的参与者在短期残疾方面没有显着差异。与 CR 组相比，LLLT 联合 CR 在短期内改善了疼痛（MD，-2.0；95% CI：2.9 至 -1.1，I ² = 0%；2 项研究，N = 90：中等质量证据）（ 0-6 周）。与体外冲击波疗法相比，LLLT 在短期内并未显着降低疼痛强度（MD，0.5；95% CI：2.0 至 2.9，I ² = 96%；4 项研究，N = 175：低质量证据）。
