RESUMO:

The throwing movement imposes an excessive stress on the glenohumeral joint (GU), since during these movements a very high angular velocity is generated, leading this joint to suffer with great traction forces. Repeated performance of such movements generates some bone, joint capsule and muscle adaptations that culminate in the development of the posterior stiffness of the shoulder and the Glenoumeral Internal Rotation Deficit, known as GIRD. As a consequence of these deficits, there is an association of a decreased range of motion (ROM), imbalance of muscle strength between medial and lateral rotators and shoulder proprioception, which increases the risk of osteomyoarticular lesions. The objective of this study was to analyze the influence of GIRD on biomechanics and neuromuscular performance of the shoulder complex of thrower athletes. It was an observational cross-sectional study of 61 athletes practicing handball and beach handball (34 males and 27 females, 27.03 ± 5.99 years, BMI 25.58 ± 3.84) and 23 non-athletes (11 men and 12 women, 26.26 ± 4.32 years, BMI 23.61 ± 2.78). There were evaluated: ROM for medial (MR) and lateral (LR) rotations and horizontal shoulder adduction (HA); sense of joint position of shoulder during ROM of LR using an Accumar® digital inclinometer; and isometric ROM of LR and MR strength using a Lafayette® manual dynamometer for both groups (athletes and non-athletes). Based on the ROM for MR evaluation, athletes with shoulder differences between limbs of less than 10º were allocated to the group without GIRD (44 individuals) and those with a difference greater than 10º in the group with GIRD (17 individuals). The statistical analysis used was one-way ANOVA for all demographic variables, comparison of differences between groups and difference between dominant shoulder (DS) and nondominant shoulder (NDS) for ADM's (MR, LR and HA). And two-way ANOVA for comparison between groups and limbs, for the MR, LR, total, and HA ROMs, sense of joint position, LR and MR strength variables and LR/MR force ratio. And, when necessary, the post hoc tests of Tukey were employed. P <0.05 was considered. As a result, group-to-limb interaction was observed for the MR variable MR (p <0.01), difference between groups in LR ROM (p = 0.03) and limb difference for ROM of HA (p = 0.005). For the sense of joint position there was no difference between members or groups. In the evaluation of strength in the three groups there was difference between the groups in the strength of LR and in the LR/MR force ratio (p≤0.01). Throwing athletes are subjected to large loads and repetitive movements, and from this, shoulder ROM and strength suffer alterations which can lead to an increased risk of injury.
