Introduction: Spinal cord injury results in disability, limited participation in physical activities, and mental health problems which greatly affects the quality of life of the injured person. Engaging in physical activity is necessary for optimal recovery in individuals with spinal cord injury. Chronic spinal cord injury patients suffer from many secondary complications which become a challenge for the patient and the health care community to manage due to which recovery will be complex and difficult. The aim of this study is to find out the association of physical activity with depression among chronic spinal cord injury patients at Paraplegic Centre Peshawar. Material and methods: This study was a cross-sectional survey in which a consecutive sampling technique was used. Data was collected from n=109 spinal cord injury patients in which 85 (78.0%) were males and 24 (22.0%) were females. Physical activity was measured using the PARA-SCI scale and the CESD-R-10 questionnaire was used to assess depression. Results: The average minutes of participating in mild physical activity was 67.72 ± 17.98 minutes/week, moderate physical activity was 140.79 ± 33.47 minutes/week, heavy physical activity was 21.92 ± 9.18 minutes/week and total PA was 247.93 ± 55.76. P value= .004 for mild physical activity with depression, p value= .097 for moderate physical activity with depression, p value= .137 for heavy physical activity with depression and p value= .001 for total physical activity with depression. Conclusions: Mild and total physical activity was associated with depression. Moderate and heavy physical activity was not associated with depression.
