简要总结
Introduction. Blood flow restriction therapy involves the use of an occlusion cuff placed over an extremity resulting in a partial reduction of arterial blood flow and total restriction of venous return.
Objectives. To analyse the efficacy of a physiotherapy intervention using blood flow restriction in improving upper limb strength in adult handball players.
Methods. Randomised, single-blind, clinical study. 20 athletes will be recruited and randomly assigned to the experimental and control groups. The intervention of the experimental group will consist of performing an exercise protocol after blood flow restriction. The intervention period will last 4 weeks, with a periodicity of 2 weekly sessions of 30 minutes each. The primary variable will be the strength of the triceps, epicondyle and epitrochlear musculature (pressure hand dynamometer). The secondary variable will be the muscle activation of this musculature (surface electromyography).

Three assessments will be made throughout the study: before the intervention (T0), after the experimental phase (T1) and after a 4-week follow-up period (T2). All variables will be assessed by an evaluator blinded to the assignment of the athletes to the study groups.

结局指标
主要结局
Assess the muscle strength at screening visit
时间窗: Screening visit, within the first seven days after treatment and after four weeks follow-up
Muscle strength will be assessed with a pressure dynamometer (Lafayette Manual Muscle model). The strength of the triceps brachii, epicondyle and epitrochlear musculature will be measured. The evaluation protocol used by Morin et al. will be used. The unit of measurement is the Newton (the higher the value, the greater the muscle strength). The measurements are taken bilaterally. The mean value of the 2 measurements taken shall be used as a measure.
次要结局
- Assess the muscle activation at screening visit(Screening visit, within the first seven days after treatment and after four weeks follow-up)
