Spinal cord injury (SCI) is a neurological disorder that leads to "partial or complete loss of people's motor and/ or sensory function below the level of the injury".

The PPI intervention group participants will indicate significantly greater improvements when compared with those in control group in the minutes of performing the moderate-to-rigorous physical activity, depression, chronic pain and mindfulness skills and quality of life at post-intervention, and three months follow-up. The use of psychological motivational interviewing and online face-to-face meetings will be good modalities for the people with SCI to overcome the barriers of not having face-to-face interactions and transportation problems. And the intervention would be feasible and improve SCI people's physical inactivity, depression and chronic pain as to step up the control of the modifiable risk factors for non-communicable diseases.

This study is a two-arm, single-blind pilot randomized controlled trial, and it will be adopted to evaluate or compare the effects between the Physical-Psychological Integrative (PPI) intervention group and the brief online didactic education control group.

Seventy-two participants will be recruited from the Hong Kong Direction Association for the Handicapped. 36 people with SCI will be assigned to intervention or control group. Participants in PPI Intervention group will receive a Fitbug wristband activity trackers and exercise bands as an incentive and encouragement for doing more physical exercises. The intervention includes eight weekly online group sessions. Qualitative interviews with the PPI intervention group participants will be conducted to understand their acceptance and perceived strengths and limitations of the intervention programme. While the one in the control group will receive a short video call for general physical and psychological suggestions. This can help to control the contact effects of the PPI intervention. Primary outcomes will be leisure-time physical activity, depression and chronic pain. Secondary outcome will be exercise efficacy.
