Twenty participants aged 18 - 65 years with plantar fasciitis will be recruited and randomized to (1) dry needing and stretching exercise group or (2) stretching exercise group, receiving three treatment sessions over three weeks. The primary outcome measure will be numeric pain rating scale (NPRS) and the secondary outcome measures will be Chinese Foot and Ankle Outcome Score (FAOS), modified Star Excursion Balance Test (mSEBT) and weight bearing lunge test (WBLT) measured at baseline and week 4.
Plantar fasciitis could lead to pain, disability and impaired balance. Dry needling that targets myofascial trigger points (MTrPs) has been shown to be beneficial in reducing pain, improving range of motion and function in patients with musculoskeletal conditions. Previous systematic review suggested a positive effect of dry needling on improving pain intensity and pain-related disability in patients with plantar heel pain (Llurda-Almuzara et al., 2021). However, the generalisability of the result is limited by small number of trials and heterogenicity in the dry needling application. Also, there is currently no evidence on its effect on dynamic balance and ankle dorsiflexion range of motion. This randomized controlled trial is designed to investigate the effectiveness of dry needling on pain, pain-related disability, dynamic balance and ankle dorsiflexion range of motion in patients with plantar fasciitis.
