The Effect of Low Dose Extracorporeal Shock Wave Therapy (ESWT) on Plantar Fasciitis: A Trial Study in Queen Mary Hospital: 低劑量體外衝擊波治療(ESWT)對足底筋膜炎的影響 - 在瑪麗醫院的試用研究

Background/PurposeTo assess the efficacy of low-energy extracorporeal shockwave therapy (ESWT) for the treatment of plantar fasciitis.MethodsThis was a prospective case series study that was performed at the Department of Orthopaedics, Queen Mary Hospital, Hong Kong. Twenty-one symptomatic feet in 16 patients with persistent symptoms of plantar fasciitis despite 3 months of conservative treatment were recruited in November 2008. All patients received five sessions of low energy ESWT and their corresponding 10-point visual analogue scale scores were recorded before and after each treatment sessions for each symptomatic foot. The patients were assessed for up to 6 months post-treatment.ResultsThe mean visual analogue scale scores reduction for pain on first step in the morning, daily activities, and heel compression test were 2.62 (44.3%), 3 (38.3%), and 1.6 (36.8%), respectively, post-treatment. The analgesic effect was maintained in 52.3% (n = 11) of the patients at 6 months post treatment.ConclusionLow energy ESWT was shown to be an effective outpatient treatment option for patients with plantar fasciitis.

中 文 摘 要目的為了評估低能量體外衝擊波治療(ESWT)為足底筋膜炎的治療的功效。設計前瞻性病例系列。單位骨科，瑪麗醫院香港。方法16個患有足底筋膜炎(共21隻腳)，接受3個月保守治療但症狀持續存在的病人在2008年11月被招募參加研究。所有病人接受低能量體外衝擊波治療(ESWT)5次，並記錄每隻腳在治療前後對應的疼痛分數(以10點視覺模擬評分法VAS記錄)。所有病人在治療後6個月都會接受再評估。結果在早晨第一步，日常活動和腳跟壓力試驗中，平均治療後VAS評分減少疼痛為2.62（44.3％），3（38.3％）和1.6（36.8％）。鎮痛效果能夠在治療後6個月保持的有52.3％（11例）。結論低能量體外衝擊波治療是治療足底筋膜炎的有效治療選擇。
