Background: Pulsed electromagnetic field (PEMF) therapy is a potential nonoperative treatment for Achilles tendinopathy, but the current published literature on its effects is sparse.

Purpose: To evaluate the therapeutic efficacy of PEMF therapy and eccentric exercise for Achilles tendinopathy.

Study Design: Randomized controlled trial; Level of evidence, 1.

Article Synopsis
  • The study investigates the use of Pulsed Electromagnetic Field therapy (PEMF) as an adjunct treatment for patients with Achilles tendinopathy (AT), which causes pain and limits exercise.
  • It is designed as a randomized double-blind placebo-controlled trial, comparing an active treatment group using PEMF and eccentric exercise against a control group using sham treatment and eccentric exercise over a period of months.
  • The goal is to determine if PEMF can help reduce pain and improve the ability to engage in eccentric exercises, potentially leading to better recovery outcomes for those suffering from AT.

Background: The incidence of Achilles tendinopathy has risen over the past decades. Insertional Achilles tendinopathy is characterised by tissue degeneration of the Achilles tendon from its insertion in the calcaneus to up to 2 cm proximally. This clinical condition is accompanied by pain, loss of function and diminished exercise tolerance.

Hallux valgus (HV) is a common foot deformity that is more prevalent in females, characterised by abnormal adduction of the first metatarsal (MT) and valgus deviation of the phalanx on the transverse plane. Increasing evidence indicates that HV is more than a 2D deformity but a 3D one with rotational malalignment. Pronation deformity is seen during clinical examination for HV patients, but the exact origin of this rotational deformity is still unknown.

Background: Victorian Institute of Sports Assessment (VISA-A) is a patient-reported outcome for assessing symptoms severity associated with Achilles tendinopathy (AT). It is a valid and reliable tool that has been used widely for measuring and monitoring treatment outcomes for AT. This clinical measurement study aims to develop a Chinese version of the VISA-A questionnaire.
