This is a systematic review of two randomised clinical trials (RCTs) on the efficacy of deep transverse friction massage in the treatment of tendinitis. These RCTs showed no benefit of deep transverse friction massage combined with concurrent physiotherapy modalities, when compared to either a control group with the same physiotherapy modalities, excluding deep transverse friction massage, or other active therapies such as phonophoresis or therapeutic ultrasound combined to placebo ointment, for the following outcomes: pain relief involved in the iliotibial band friction syndrome in runners, pain relief, improved functional status and increased grip strength involved in extensor carpi radialis tendinitis. These conclusions are limited by the lack of studies available, the use of subjective and non-validated scales for measuring pain, the combination of several physiotherapy modalities and the low sample size of the RCTs included in this systematic review.
