Brief summary
Tendinopathy of the flexor hallucis longus (FHL), colloquially referred to as dancer's tendinitis, is a common condition in dancers and attributed to high demand on this muscle in positions of extreme ankle plantarflexion and metatarsophalangeal (MTP) flexion and extension. Tradicional conservative treatment includes rest from pain-inducing activities including pointe work and jumping, physical therapy a focusing on movilization of the joints of the first ray and subtalar joint, and antiinflamatory medications. Unfortunately, dancer frecuently do not follow recommendations to rest due to the competitive nature of the field. Those who do not respond to conservative treatment undergo more serious interventions including steroid injections or surgery, each with additional risks and recovery time. To develop experimental protocols aimed at prevention and nonsurgical interventions are needed. Therefore, the aim of this study was To investigate the effects of one shot of low-frequency percutaneous electrical nerve stimulation (PENS) vs. one shot of transcutaneous electrical nerve stimulation (TENS) in performance of the Flexor Hallucis Longus muscle in young dancers.
Interventions
This intervention consisted in the application of an asymmetric biphasic rectangular current of 150 microseconds and 10 Hz using a specifically developed medically certified device (Physio Invasive, Enraf Nonius, Prim, SPAIN). This is an invasive intervention by ultrasound and needles.
