Although there are numerous studies that have demonstrated decreased nociceptive sensitivity after dry needling treatment (Ge, Fern andez-de-LasPeñas, Madeleine and Arendt-Nielsen, 2008;Hsieh et al, 2007;Mejuto-V azquez, Salom-Moreno, Ortega-Santiago, Truyols-Domí-nguez, & Fern andez-de-las-Peñas, 2014;Srbely et al, 2010;Tsai et al, 2010), only one human study has investigated the effects of dry needling on muscle function (Jimbo et al, 2008). In a small sample of patients with neck pain, this study found no changes in muscle oxygenation immediately after needling, but reported improved aerobic capacity (quicker recovery after a fatiguing bout of exercise) of the trapezius muscle one day after needling in the majority of patients.…”
