Clinical Trial Summary

Immediately following a spinal cord injury (SCI), patients are admitted to inpatient rehabilitation where they undergo physical reconditioning in preparation for a return to home setting. The current standard of practice for aerobic training is performing arm-ergometry for 25 mins at a frequency of three times per week. Given the move towards shortened length of stay during inpatient rehabilitation, performing MICT can consume a considerable amount of therapy time. Sprint interval training (SIT) has been shown to elicit similar improvements in physical capacity, despite a reduced time commitment to MICT. However, there are no controlled trials comparing the effects of SIT to MICT in individuals with SCI undergoing inpatient rehabilitation. The primary aim of this study was to investigate the efficacy of a five-week, thrice weekly 10 min SIT program and compare outcome measures to a traditional 25 minute MICT program on the arm-ergometer in individuals with SCI undergoing inpatient clinical rehabilitation. It was hypothesized that five weeks of SIT and MICT would induce similar changes in maximal and sub-maximal exercise performance, self-efficacy for exercise, and exercise enjoyment, despite large differences in training volume and time commitment. It was also hypothesized that SIT would be well tolerated and elicit higher levels of cardiovascular strain than MICT.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in peak power output	maximum amount of power produced during a graded exercise test on the arm-ergometer	Change in peak power output from baseline to 5 weeks
Primary	Change in sub-maximal arm-ergometry	Participants performed three 5-minute steady state workloads on the arm-ergometer at power outputs corresponding to RPE's of 8, 10 and 12. Participants were given a minimum of 2 minutes, and a maximum of 5 minutes of rest in between each workload.	Change in sub-maximal arm-ergometry from baseline to 5 weeks
Secondary	Cardiovascular Responses	Monitored heart rate throughout each training session	Throughout each week of training (Week 1,Week 2, Week 3, Week4, Week 5)
Secondary	Perceptual Responses	Monitored ratings of perceived exertion throughout each training session	Throughout each week of training (Week 1,Week 2, Week 3, Week4, Week 5)
Secondary	Change in self-efficacy for exercise	Using a self-reported questionnaire, participants rated how confident they are with regards to performing and carrying out regular physical activities and exercises.	Change in self-efficacy from baseline to 5 weeks
Secondary	Exercise Satisfaction	Participants completed the Physical Activity Enjoyment Scale (PACES) in order to asses the level of enjoyment with the training intervention they received.	Measured only at the end of the intervention (5 weeks)
Secondary	Pain perceptions	Through a questionnaire, participants rated how much shoulder pain, bodily pain, and physical discomfort they typically experience throughout the day and how much pain they experienced with the intervention they were allocated to.	Measured only at the end of the intervention (5 weeks)
