Protocol of Action in Injuries of the Long Head of the Biceps Tendon. Joint Reference Values and Recommended Training Weight for the Recovery of Joint Range and Strength

Daily and sports activities can be affected by joint injury. The objectives of physical therapy are to help patients regain range of motion (ROM), mobility, strength, and function. The purpose of this study was to examine the optimal joint range of elbow flexion and recommended training weight for the recovery of biceps brachii muscle strength. It was a prospective study with a sample of 157 healthy young adult volunteers from two institutions. The Hawk goniometer was used for measurements. Participants performed a flexion-extension movement of the elbow in standing, in series, with progressive loads. The ROM in males was found to be higher than in females. Nevertheless, the joint values of the dominant and non-dominant arm indicate that there are differences between both arms, regardless of gender. In relation to the force used during the performance of the activity, the weight used by the women was lower than that of the men, whereas, during the execution, women showed greater stability throughout the test, compared to men. Normative values have been established for the ROM and weights to be used in the recovery process of injuries to the long tendon of the biceps brachii muscle.
