Efficacy of Extracorporeal Shock Wave Therapy in Neck and Shoulder Pain Syndrome / 대한스포츠의학회지

ABSTRACT

Purpose@#The aim of current study is to verify the efficacy of extracorporeal shock wave therapy (ESWT) in neck and shoulder pain syndrome. @*Methods@#We enrolled 23 patients with neck and shoulder pain syndrome (mean age, 55±16 years; onset, 12.65±8.90 months) who underwent ESWT from July to December 2019. ESWT (4 to 5 bar or 0.23–0.45 mJ/mm 2 , 1,500 to 2,000 times/region, 7 Hz) was performed at least 4 consecutive times per week. Evaluated outcomes were visual analogue scale (VAS) of pain and tenderness, neck disability index (NDI), and shoulder passive range of motion (ROM; forward flexion [FF], external rotation at neutral [ER], internal rotation at back [IR]). Pain and tenderness VAS scores were assessed at every follow-up, while NDI and shoulder ROM were evaluated two times before treatment and at the final follw-up (at 4.52±0.73 weeks). @*Results@#The pain VAS score decreased from 5.5±2.4 at first visit to 4.0±1.8 (p=0.001), 3.3±2.1 (p=0.02), and 3.1±2.2 (p=0.29) at the first, second, and third follow-up visits. The tenderness VAS at first visit was 5.98±1.89, which decreased to 5.17±1.83 (p=0.005), 4.61±1.67 (p=0.05), and 4.09±1.92 (p=0.06) at the first, second, and third follow-up visits. NDI was significantly reduced from 18.04±8.86 to 10.04±6.94 at last follow-up (p=0.001) and shoulder ROM was significantly improved after treatment (FF 159.6°±28.0° to 177.8°±8.5°, p=0.001; ER 72.2±15.7° to 79.6±2.1°, p=0.02; IR 10.2±3.49 [T 10] to 6.9±1.7 [T 7], p=0.001). @*Conclusion@#Consecutive ESWT was effective in treating neck and shoulder pain syndrome with functional improvement and pain reductio
