Plain English Summary
Background and study aims
Individuals with spinal cord injury generally have a sedentary (inactive) lifestyle, which negatively impacts their fitness level and quality of life. Moreover, those with SCI are at increased risk of developing long-term health conditions such as type 2 diabetes, heart disease and metabolic syndrome (a group of conditions which increase a person's risk of heart attack or stroke). Therefore, promoting an active lifestyle for those with SCI is important for the prevention of these diseases. The aim of this study are to assess the effects of personalized exercise programs on insulin (the hormone which converts sugar in the blood into stored sugars) and fitness levels of people with spinal cord injury.
Who can participate?
Patients with Spinal cord injury
What does the study involve?
Patients are randomly allocated to either the exercise group or the control group. Those in the exercise group receive a six-week combined exercise program. Participants will exercise for 60 minutes per session, three times per week for six weeks. The daily exercise programs consist of a 25-minute warm up consisting of 5 min of joint exercises, 15 min of exercise on an arm ergometer, and 5 min of stretching, followed by a 30-minute exercise program (resistance, circuit, and aerobic training), and a 5-minute cool down (stretching). Those in the control group are instructed to continue with their usual daily activities. At the start of the study and after six weeks, participants in both groups provide blood samples to assess their insulin and blood sugar levels, and complete questionnaires about their quality of life and mood. In addition. participants have their fitness levels assessed.
What are the possible benefits and risks or participating?
Participants allocated to the exercise group will receive the thera-band, and results of clinical tests. There are no known risks to participants.

Spinal cord injury
Participants will be randomized to one of two groups using the minimization method.
Intervention group: Participants will receive a 6-week combined exercise program. Participants will exercise for 60 minutes per session, three times per week for six weeks. The daily exercise programs consist of a 25-minute warm up consisting of 5 min of joint exercises, 15 min of exercise on an arm ergometer, and 5 min of stretching, followed by a 30-minute exercise program (resistance, circuit, and aerobic training), and a 5-minute cool down (stretching).
Control group: Participants will be instructed to continue with their usual daily activities.
Participants in both groups will be followed up after six weeks.
Primary outcome measure
1. Fasting glucose is measured using ADVIA 1650 Chemistry System at baseline and six weeks
2. Insulin is measured using Roche Chemistry System at baseline and six weeks
3. Insulin resistance will be estimated according to the homeostasis model assessment of insulin resistance (HOMA-IR) index at baseline and six weeks
Secondary outcome measures
1. Total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C) levels will be measured using an ADVIA 1650 Chemistry System at baseline and six weeks
2. Upper body strengh will be measured by a hand-held dynamometer at baseline and six weeks
3. Vo2 peak will be assessed through maximal graded exercise tests, performed using a ramp protocol at baseline and six weeks.
4. Quality of life will be measured using the SF-36 questionnaire at baseline and six weeks
5. Anxiety and depression will be measured using the Generalized Anxiety Disorder 7-item (GAD-7) scale and Patient Health Questionnaire (PHQ-9) at baseline and six weeks
