acupuncture vs sham acupuncture or waitlist control for patients with chronic planter fasciitis

Conditions: Plantar Fasciitis

Summary: plantar fasciitis (pf) predominantly affects elderly and middle-aged individuals and is more frequent in runners or those whose employment requires standing. the available treatment options of pf mainly included non-operative treatments (e.g., plantar fascia and gastrocnemiussoleus muscle stretching, heel cups, arch supports, night splints, nonsteroidal antiinflammatory drugs (nsaids), local corticosteroid injections) and operative management. however, no consensus has been reached regarding the most beneficial treatment method for pf. acupuncture has been used in the management of pf and the other musculoskeletal pain-related conditions for thousands of years. recent two systematic reviews have found that acupuncture may reduce pain intensity and improve plantar function for patients with pf. however, there are methodological problems with small sample size, or not controlled with a placebo/waitlist group, or not account for the confounding effects of patients who experienced combination treatments in the design of the included acupuncture literature. therefore, the placebo effect of acupuncture and a possible spontaneous remission for pf cannot be excluded and the beneficial effects of acupuncture for pf remained need to more assessment. the investigators designed a randomized controlled trial to evaluate the efficacy of traditional chinese acupuncture (tca), compared with sham acupuncture (sa) or being on a waitlist control group (no acupuncture treatment), for patients with chronic pf for ≥ 6 months. the hypothesis was that combined acupuncture and sham acupuncture will result in larger improvements in heel pain more than no acupuncture treatment in patients with chronic pf. secondary hypotheses examined whether acupuncture reduce heel pain intensity more effectively than sham acupuncture or no acupuncture.
