Introduction: Pain is a common symptom experienced by patients with plantar fasciitis (PF), affecting their body function, daily activities and quality of life. This quasi-experimental research aimed to examine the effects of low-en- ergy radial extracorporeal shockwave therapy (rESWT) on the pain severity among patients with PF attending the Physiotherapy Clinic, International Islamic University Malaysia (IIUM), Kuantan campus. Methods: Twenty-one pa- tients diagnosed with PF were enrolled in a single intervention group receiving three sessions of low energy rESWT (pulses: 2000 impulses, rate: 8 impulses per second, dosage: 0.16 mJ/mm2) in three weeks. Pain severity was assessed by using a pain assessment tool, the visual analogue scale (VAS). The data acquired were analysed using SPSS 21 software. Results: There was no significant difference in pain score between genders (p=0.77), but there was a sig- nificant difference between occupations (p=0.04). The pain score was significantly reduced following administration of low energy rESWT (p<0.01). Conclusion: In three weeks, low energy rESWT treatment reduces the pain severity, thus providing an alternative to a high-energy dosage of rESWT in managing patients with PF.
