- Abstract
Purpose: Currently, wheelchair basketball classification is conducted by subjective means. The current study is a step towards an objective measure of trunk function to be utilized for wheelchair basketball classification. The measure is a field test that could be easily transported to competition locations. Methods: 10 people with disability and 10 people without disability were recruited to participate. The participants sat upon a constructed seat and pushed a force gauge against a wall. The constructed seat had a removable backrest. The participants pushed against the wall with and without support in 3 directions (front, left, and right). The loss in support was calculated to a percentage of the with support condition force measure. This percentage became a trunk stability score. Surface electromyography was utilized to measure the bilateral activity of the pectoralis major, rectus femoris, rectus abdominus, and erector spinae. Results: A significant group difference in the trunk stability score was found (PWD = 27.40 ±2.91, PWOD = 16.67 ±2.91, p=.018). The group with disability produced similar force to those without disability in the support conditions (PWD = 255.97 N ±95.57, PWOD = 238.87 N ±71.27, p=.082). The group with disability produced less force in the without support conditions (PWD = 145.47 N ± 58.40, PWOD = 160.2 N ±38.32, p=.082) Conclusion: The proposed field test is able to detect differences in trunk stability. More research is needed to find the ability of the test to stratify across enough functional levels to be used for wheelchair basketball classification.
