This study will assess the feasibility and efficacy of 3 treatments to increase physical activity during and after inpatient rehabilitation (IPR) for new spinal cord injuries: 1. Program of sprint interval training (SIT) on an arm crank ergometer during IPR 2. SIT + Provision of an arm ergometer (ERGO) for home use 3. SIT + ERGO for home use + Motivational interviewing to increase adherence to exercise during and after IPR. The primary outcome is minutes per week of moderate to vigorous physical activity at 6 months after IPR discharge. Secondary outcomes include peak power on the 6-Minute Arm Test at IPR discharge and self-reported physical activity, depression, fatigue, pain, community participation, and quality of life at 6 months after IPR discharge. The investigators will obtain data on feasibility, acceptability, and perceived benefits of the treatments from stakeholders. The results of this pilot study will inform the design of a larger randomized trial.
Description of the Sprint Interval Training Condition The SIT treatment procedures will parallel the procedures used in the successful comparative effectiveness trial of SIT versus Moderate Intensity Continuous Training (MICT) during IPR in Canada. SIT participants will be trained to use an ergometer on a Monark 881 mechanically braked arm ergometer purchased for the study. The Monark will be mounted on a rolling table designed for this purpose, so training can take place in patient rooms or in one of several small therapy rooms adjacent to the inpatient rehabilitation unit. Sessions will be…
Inclusion Criteria: 1. Adults with SCI 2. SCI below C2 3. AIS A-C 4. aged 18-65 5. undergoing acute IPR for SCI at Harborview Medical Center 6. Able to use an arm ergometer Exclusion Criteria: 1. poorly controlled type II diabetes 2. unstable cardiovascular disease 3. shoulder injury 4. any other medical condition that would preclude safe participation in study procedures.
Participants will undergo 1:1 therapist supervised SIT for 10 minutes per day, three times per week during IPR using a Monark 881 arm crank ergometer.
Participants will have the opportunity to participate in optional group endurance exercise classes two to three times a week.
Participants complete the SIT intervention during IPR and be provided with a consumer-grade ergometer. Study staff will train the participants in the set-up and use of the home ergometer prior to discharge and arrange for take home or delivery.
Participants complete the SIT intervention during IPR and be provided with a consumer-grade ergometer. Study staff will train the participants in the set-up and use of the home ergometer prior to discharge and arrange for take home or delivery. These participants will also receive weekly Motivational Interviewing (MI) counseling sessions during IPR plus six post-discharge MI sessions delivered via telehealth to be held over six months.
