“…Even considering the pre-established context in which handball athletes who perform a large number of shots and passes can present an upward trend of ROM external rotation and reduction in WMD internal rotation of the dominant glenohumeral joint (5,6) in the present study no significant difference or treatment effect was observed for increased internal rotation or reduction in external rotation at the shoulder of the athletes. It is thought that the small effect generated by NEB may be related to the high muscular fitness, together with the low level of disability and mild pain of the athletes evaluated.…”

“…These disorders are triggered by microinjuries generated by repetitiveness and may result in prejudice to performance of the sport gesture and hence athlete performance. The most common alterations found are the onset of pain, shoulder instability, scapular dyskinesia (1) , an increased range of motion (ROM) of external rotation and a reduction in ROM of internal rotation of the glenohumeral joint in the dominant shoulder performing the throwing gesture (5,6) . Recent investigations in handball athletes point to the need to carry out rehabilitation programs that aim to improve the instability of the glenohumeral joint, widely used in the various tasks of this modality (7,8) .…”

Background: Recent investigations in handball athletes point to the need to carry out rehabilitation programs that aim to improve the instability of the glenohumeral joint, widely used in the various tasks of this modality. Objectives: To evaluate the immediate and short-term effects of a neurofunctional elastic bandage (NEB) on muscular strength, range of motion and pain intensity in the glenohumeral joint in handball athletes with shoulder dysfunction. Method: This study was composed of 20 professional male handball athletes who presented shoulder pain at rest and dysfunction of the shoulder, divided into two groups; experimental (n = 10) and placebo (n = 10). Before and one hour after the application of NEB the following were evaluated: maximal isometric muscular strength during movements of the glenohumeral joint (load cell), the range of motion (ROM) of the glenohumeral joint (fleximetry), pain intensity in the shoulder at rest and during movement, and the pressure pain threshold (algometry). NEB was maintained for 72 hours in all volunteers, during which a diary of shoulder pain was recorded for the short-term assessment. We used the ANOVA two-way repeated measures considering the possibility of group by time interaction, adopting a 5% level for significant differences. The treatment effect size was analyzed by means of Cohen's d values. Results: There was no group by time interaction for any of the variables (p> 0.05), however, there was a large effect of the treatment for reducing pain in the experimental group after the application of NEB in the short-term period (d = 0.83). Conclusion: There were no significant effects on muscular strength, range of motion or pain intensity in the shoulder in handball athletes immediately after implementation of NEB.

“…Dines et al 4) reported that adolescent pitchers with side-to-side differences in shoulder IR ROM of >13° had 6 times greater risk of throwing injuries. Shanley et al 5) reported that a shoulder IR ROM deficit on the throwing side was 15.8° greater in players with ulnar collateral ligament insufficiency than in those who were asymptomatic.…”

“…Therefore, we conclude that the shoulder IR ROM deficit in our study is a change that appears in baseball players in general. However, a notable change in shoulder IR ROM provokes medial elbow injuries 4,5) . Muscular tightness 3,34) , posterior capsular tightness 35,36) , and scapular position 37) induced by repetitive throwing are all involved in shoulder IR ROM deficits.…”

“…It is widely known that shoulder external rotation (ER) ROM tends to increase, while shoulder internal rotation (IR) ROM tends to decrease on the throwing side compared to the non-throwing side in adult baseball players [1][2][3] . In particular, shoulder IR ROM deficit was found to be a risk factor for medial elbow injuries 4,5) . In addition, Brown et al 6) reported that ROM of elbow extension, flexion, and forearm supination decreased on the throwing side compared to the non-throwing side in professional baseball pitchers.…”

Medial elbow injuries lead to significant performance decrement in baseball.Repetitive throwing alters mechanical physiology. Some of such changes can increase the risk of medial elbow injuries. However, in young baseball players with medial elbow injuries, these changes have not been fully investigated. Thus, the purpose of this study was to investigate the mechanical physiological changes in young baseball players with medial elbow injuries. Sideto-side differences in (1) range of motion (ROM) of shoulder external rotation (ER)/internal rotation (IR), elbow flexion/extension, forearm supination/pronation, trunk rotation, and hip ER/IR; (2) strength of middle trapezius, lower trapezius (LT), and supraspinatus muscles, and shoulder ER/IR; and (3) medial elbow laxity were measured. Side-to-side differences were significant (p < 0.05). ROM of shoulder ER/IR, elbow flexion/extension, forearm pronation, and hip IR on the throwing side were significantly decreased compared to the non-throwing side. Trunk rotation in the direction of the throwing side was significantly decreased compared to the non-throwing side. LT and shoulder IR strength on the throwing side were significantly greater, while shoulder ER strength on the throwing side was significantly weaker than the non-throwing side. Medial elbow joint space of the throwing side was significantly wider than the nonthrowing side. In other measurements, no significant differences were observed between the throwing and non-throwing side. According to our findings, young baseball players with medial elbow injuries experience many side-to-side differences in mechanical physiology. The most interesting finding was that younger players with medial elbow injuries displayed decreased shoulder ER ROM, versus an increase reported in many previous studies.
