This study evaluated the additive effect of myofascial release therapy on the brachial biceps on conventional management (TENS) in pain intensity, hand prehensile strength and upper limb functionality of individuals with lateral epicondylalgia.

This study determined the additive effect of the myofascial release therapy of brachial biceps on TENS in the variables pain intensity, hand prehensile strength and upper limb functionality of individuals with lateral epicondylalgia, compared to a group that received only TENS. This was done in a sample of 32 individuals, assigned in two groups: group A that received an application of TENS and group B that received an application of TENS plus myofascial release therapy.

Contrary to the hypothesis, the application of myofascial release therapy added to the application of TENS proved to generate a significant change only in the prehensile hand force with respect to the group that received only TENS.

Inclusion Criteria:

• Female between 30 and 50 years old.
• Belong to the administrative staff of the university in question
• Have a symptomatic diagnosis of chronic lateral epicondylitis (> 6 weeks)

Exclusion Criteria:

• Being pregnant
• Have done moderate or intense aerobic or anaerobic sport activities of any kind 72 hours before the registrations
• Have an orthopedic, rheumatologic, neuropsychiatric or associated comorbidities diagnosed.
• Have suffered a fracture or trauma involving the upper extremity 4 months before the intervention.
• Be in medical, pharmacological or kinesthetic treatment during the intervention or 2 weeks before this.

The hidden assignment of the participants was carried out using the method of opaque envelopes sealed and numbered consecutively.

The assessor in charge of evaluating the participants was blind to the treatment assignment, where he proceeded to take the measurements with a prior instruction of the procedures.
