“…rESWT for entrapment neuropathy has been shown to reduce VAS, Boston Carpal Tunnel Questionnaire (BQ), and sensory nerve action potential distal latency [ 8 - 10 ]. In patients with piriformis syndrome, a randomized controlled trial of rESWT versus corticosteroid injection showed that both groups had improved VAS [ 11 ]. The present study demonstrated not only a reduction in pain but also a reduction in piriformis hardness and cross-sectional area of the sciatic nerve with respect to the effect of rESWT on piriformis syndrome.…”

“…Moreover, some reports have indicated the potential efficacy of rESWT in carpal tunnel syndrome, an entrapment neuropathy [8][9][10]. Regarding the impact of rESWT on piriformis syndrome, one previous study [11] has evaluated its efficacy using the Visual Analogue Scale (VAS) and SF-36; however, it remains unclear how rESWT affects the pathophysiology of piriformis syndrome.…”

The effects of radial extracorporeal shockwave therapy (rESWT) on piriformis syndrome were investigated using a single-case study design.This study used an AB single case with a follow-up phase design. The baseline phase consisted of general physical therapy, including piriformis stretching, while the experimental phase consisted of rESWT in addition to general physical therapy. A man in his 70s diagnosed with piriformis syndrome participated in the study. The Numerical Rating Scale (NRS) score, piriformis hardness, and cross-sectional area of the sciatic nerve were measured to determine the effectiveness of the intervention. The baseline and experimental phases were compared using a binomial distribution based on the celeration line.The NRS score, piriformis hardness, and cross-sectional area of the sciatic nerve were significantly decreased in the experimental phase compared to the baseline phase (NRS, p<0.001; piriformis hardness, p<0.001; cross-sectional area of the sciatic nerve, p<0.001). This effect was carried over to the follow-up phase for all variables. rESWT for piriformis syndrome improved the clinical symptoms, piriformis hardness, and cross-sectional area of the sciatic nerve. However, these results are exploratory and require further validation in future clinical trials.
