Objective: To examine whether the psychological bene®ts of sports activity di er between tetraplegics and paraplegics with spinal cord injury, and investigate the e ect of frequency and modes of sports activity on the psychological bene®ts. Methods: The Self-rating Depression Scale (SDS), State-Trait Anxiety Inventory (STAI) and Pro®les of Mood States (POMS) were administered to 169 male individuals with spinal cord injury (mean age=42.7 years) including 53 tetraplegics and 116 paraplegics. The subjects were divided into four groups according to their frequencies of sports activity; High-active (more than three times a week; n=32), Middle-active (once or twice a week, n=41), Low-active (once to three times a month, n=32), and Inactive (no sports participation, n=64). Results: Analysis of variance revealed signi®cant di erences in depression for SDS, trait anxiety for STAI and depression and vigor for POMS among the groups. High-active group showed the lowest scores of depression and trait anxiety and the highest score of vigor among the four groups. In contrast, no signi®cant di erence was found for any psychological measurements between tetraplegics and paraplegics. In addition, there was no signi®cant di erence for any psychological measurements among modes (wheelchair basketball, wheelchair racing, wheelchair tennis and minor modes). Conclusions: These ®ndings demonstrated that sports activity can improve the psychological status, irrespective of tetraplegics and paraplegics, and that the psychological bene®ts are emphasized by sports activity at high frequency.
