چکیده

Shoulder kinesthesia has not been extensively studied in upper extremity athletes. The purpose of this study was to determine if there were differences in threshold to detection of passive motion between dominant and nondominant shoulders of healthy overhead athletes in two positions, 0 degrees and 75 degrees of external rotation. In addition, the study attempted to determine if there was a relationship between the range of external rotation (ER) and internal rotation (IR) and the threshold to detection of passive motion values. Shoulder kinesthesia was assessed in the dominant and nondominant shoulders of 20 collegiate athletes participating in unilateral upper extremity sports. A proprioceptive testing device passively moved the shoulder into internal and external rotation. The dominant shoulder had a significantly greater difficulty detecting motion compared with the nondominant arm at both 0 degrees and 75 degrees of external rotation. Both shoulders exhibited enhanced kinesthesia (lower threshold to detection of passive motion scores) at 75 degrees of external rotation compared with 0 degrees, where the glenohumeral joint capsule is relatively taut. The results of this study suggest that healthy upper extremity athletes may have kinesthetic deficits in their throwing shoulder compared with their nondominant shoulder.

Shoulder kinesthesia after anterior glenohumeral joint dislocation.

The purpose of this study was to examine kinesthesia in normal (uninjured) shoulders and in shoulders with a history of glenohumeral joint dislocations. Both shoulders of 10 healthy subjects and 8 subjects with a history of unilateral anterior dislocation were tested for accuracy of angular reproduction, threshold to sensation of movement, and end-range reproduction using a motor-driven shoulde...

Generalized Ligamentous Laxity: An Important Predisposing Factor for Shoulder Injuries in Athletes

BACKGROUND Generalized ligamentous laxity is defined as an increased range of joint motion compared to that of the general population. It is a predisposing factor for sports injuries, especially in the lower extremities. Nevertheless, there is little evidence about the relationship between generalized ligamentous laxity and sports injuries in the upper extremities. OBJECTIVES To evaluate the ...

Mirror Electromyografic Activity in the Upper and Lower Extremity: A Comparison between Endurance Athletes and Non-Athletes

During unimanual motor tasks, muscle activity may not be restricted to the contracting muscle, but rather occurs involuntarily in the contralateral resting limb, even in healthy individuals. This phenomenon has been referred to as mirror electromyographic activity (MEMG). To date, the physiological (non-pathological) form of MEMG has been observed predominately in upper extremities (UE), while ...

Shoulder pain in adolescent athletes: prevalence, associated factors and its influence on upper limb function

BACKGROUND Sports that require the constant use of an upper limb demand the maximum kinetic chain efficiency in this segment. Immaturity of the musculoskeletal system, followed by failure in motor skills can expose adolescents to major reports of pain complaints, particularly for the shoulder. OBJECTIVE To evaluate the prevalence of shoulder pain in adolescent athletes and identify possible f...
