Comparison of isometric strength, the range of motion and repositioning error shoulder between basketball player disabled and Non-athlete disabled

Frequent throwing movements can change its muscular balance strength, the range of motion and shoulder joint positioning. However, the balance of muscular strength, the range of motion and positioning are essential factors in injury prevention. On the other hand, Proprioception is a type of feedback from limbs to Central nervous system which defines a sensory tool to contribute position sense and movement sense. The purpose of this study was to Comparison of Isometric strength, range of motion and repositioning error shoulder between basketball player disabled and Non-athlete disabled. This is a Causal-comparative study. Convenience sampling was used to recruit the participants.  The participants selected from among disabled athletes and non-athletes with disabilities. A questionnaire distributed to athletic and nonathletic wheelchair-dependent populations. Sixteen man basketball players disabled (Mean and standard deviation age: 24.64±4.06 (Years), Weight: 66.33±5.12(kg), Sitting height: 79.21±7.04(cm), Years of wheelchair use:11.21±3.20 (Years), Sports activity per week:10.23±4.01(watch), Sixteen man Non athletic disabled Wheelchair Users (Mean and standard deviation age:26.25±2.02 (Years), Weight: 69.35±4.12(kg), Sitting height: 82.65±8.15(cm), Years of wheelchair use: 13.01±2.28(Years), subjects were recruited to participate in this study. In order to assess isometric strength internal rotators shoulder joints, Range of motion shoulder joints Abduction, Range of motion shoulder External Rotation joints and repositioning error shoulder joints of the subject, A hand-held Dynamometer and the  Universal Goniometer was used for measuring. The data were analyzed using independent samples t-test (p≤0.05). The results showed independent samples t-test (p≤0.05) a Significant differences between basketball player disabled and Non athlete disabled were found in isometric strength internal rotators shoulder joints, Range of motion shoulder joints Abduction, Range of motion shoulder External Rotation joints and repositioning error shoulder joints (0.001), (0.001), (0.001), (0.001). So that the disabled basketball players had isometric strength internal shoulder joints, isometric strength external shoulder joints, Range of motion shoulder Abduction joints, Range of motion shoulder External Rotation joints and repositioning error shoulder joints than non-athletes with disabilities. The results also showed that isometric strength external rotation joints in the level of (p≤0.05).there is no significant difference between basketball player disabled and Non-athlete disabled (p≤0.05). Also, the results of the study showed that the isometric strength internal rotators of the shoulders joints of the basketball players was higher than that of isometric strength external rotators joints (p≤0.05). Also, there was a significant difference between repositioning error shoulder joints in basketball player disabled and Non-athlete disabled (0.001). Basketball is the non-contact sport that needs to the eye and hand coordination, as our results showed that the muscular strength, the range of motion and shoulder repositioning error decreased in athletics-related to non-athletic subjects, the mentioned sport (Basketball) may improve muscular strength, a range of motion and shoulder repositioning error. Since The disability may be associated with functional impairments and the fact that exercise can reduce disability and maintain the function of individuals, So Designing preventive programs for controlling and limiting this risk factor should be one the main concerns of trainers and medical stuff.
