Three-dimensional kinematic data were obtained from 15 male wheelchair basketball players performing a successful free throw. Players were divided into two groups, according to their International Wheelchair Basketball Federation (IWBF) classification (Group 1: 2-2.5 point players and Group 2: 4-4.5 point players). The angle of release of the ball was 58 for both groups. Group 2 released the ball from a significantly greater height than Group 1 (1.57 – 0.12m v 1.78 – 0.17m; p < .05). Although nonsignificant, the following trends were found: Group 1 showed greater ball release speeds and generated greater angular velocity of the wrist at release while Group 2 generated greater shoulder flexion angular velocity at release. In conclusion, players from different IWBF classes tend to rely on different kinematic strategies to produce successful release conditions.

Background: Despite the fact that the number of disabled individuals participating in sports is increasing, there are only sparse reports in the literature concerning overuse injuries. Objectives: The purpose of this study was to compare scapular resting position, shoulder pain, and function in wheelchair basketball, amputee soccer, and disabled table tennis players. Study design: Descriptive study. Methods: A total of 63 disabled players from amputee soccer, wheelchair basketball, and disabled table tennis participated in our study. Scapular resting position was taken as primary outcome; pain and function were taken as secondary outcome measurements. Scapular resting position was evaluated with Lateral Scapular Slide Test. Visual Analog Scale was used for evaluating shoulder pain intensity. Quick disabilities of the arm, shoulder, and hand questionnaire were used to assess upper extremity function. Results: There was a significant difference in shoulder pain, function, and scapular resting position in all groups (p < 0.05). Paired comparisons between amputee soccer and wheelchair basketball players and also amputee soccer and disabled table tennis showed difference for all measurement parameters (p < 0.05). Conclusion: When the results are evaluated, it may be stated that amputee soccer players have better scapular resting position than other sports. Crutch usage may not negatively affect scapular resting position and perceived function as much as wheelchair usage. Exercise techniques for shoulder and resting position could be included in training programs of disabled athletes. Clinical relevance Wheelchair/crutch usage is a risk, and special exercise techniques for shoulder and dyskinesis could be included in training programs to prevent injury. However, it may not just be important for wheelchair athletes, it may also be important for amputee soccer players. In particular, total upper extremity evaluations and exercises could be added within exercise programs.

An investigation was undertaken to assess the relationship between the disability classification levels of wheelchair basketball players, as used by the National Wheelchair Basketball Association (NWBA), and the skill proficiency levels of the athlete. The assessment tool consisted of seven components deemed necessary for proficiency in basketball; these items were the 20-m sprint, free-throw shooting, obstacle dribble, baskets per minute, rebounding, speed pass, and pass for accuracy. The data used for statistical analysis were based upon the results acquired from 91 subjects who were tested in 1983. These subjects represented 18 NWBA teams from 14 states and Canada. The results of the investigation indicate support for placing less of an emphasis on the disability levels of wheelchair basketball participants, and for the development of functional assessment tools to be used in judging performances of “handicapped” athletes.
