“…Previous studies in able-bodied men and athletes with SCI have demonstrated minimal differences between T core estimations using esophageal, intestinal, or rectal probes during high-intensity exercise [27,31]. Our findings are likely specific to individuals with SCI with poor aerobic fitness performing moderate-intensity exercise, which represents the fitness and activity of the majority of untrained adults with SCI [32]. It is unknown whether exercise in heat or longer duration exercise would diminish observed differences between methods in men with paraplegia, although an exercise duration of 30 minutes is a realistic and relevant physiological challenge for most individuals with SCI.…”

Study Design: Experimental study. Objective: Individuals with spinal cord injuries (SCI) may present with impaired sympathetic control over thermoregulatory responses to environmental and exercise stressors, which can impact regional core temperature (T core) measurement. The purpose of this study was to investigate whether regional differences in T core responses exist during exercise in individuals with SCI. Setting: Rehabilitation centre in Wakayama, Japan. Methods: We recruited 12 men with motor-complete SCI (7 tetraplegia, 5 paraplegia) and 5 able-bodied controls to complete a 30-minute bout of arm-cycling exercise at 50% V O 2 peak. T core was estimated using telemetric pills (intestinal temperature; T int) and esophageal probes (T eso). Heat storage was calculated from baseline to 15 and 30 minutes of exercise. Results: At 15 minutes of exercise, elevations in T eso (Δ0.39±0.22˚C; P<0.05), but not T int (Δ0.04±0.18˚C; P=0.09), were observed in able-bodied men. At 30 minutes of exercise, men with paraplegia and able-bodied men both exhibited increases in T eso (paraplegia: Δ0.56±0.30˚C, P<0.05; able-bodied men: Δ0.60±0.31˚C, P<0.05) and T int (paraplegia: Δ0.38±0.33˚C, P<0.05; able-bodied men: Δ0.30±0.30˚C, P<0.05). T eso began rising 7.2 min earlier than T int (pooled, P<0.01). Heat storage estimated by T eso was greater than heat storage estimated by T int at 15 minutes (P=0.02) and 30 minutes (P=0.03) in men with paraplegia. No elevations in T eso , T int , or heat storage were observed in men with tetraplegia. Conclusions: While not interchangeable, both T eso and T int are sensitive to elevations in T core during arm-cycling exercise in men with paraplegia, although T eso may have superior sensitivity to capture temperature information earlier during exercise.

“…As a safety precaution, blood pressure was recorded before and after the exercise test. VO 2 peak values reported for untrained male and female adults (young and middle-aged) with SCI (paraplegia) are defined as poor (less than 12 ml·kg −1 ·min −1 ), fair (12-15.3 ml·kg −1 ·min −1 ), average (15.3-17.7 ml·kg −1 ·min −1 ), good (17.7 -22.4 ml·kg −1 ·min −1 ), and excellent (more than 22.4 ml·kg −1 ·min −1 ) [22]. …”

BackgroundSpinal cord injury (SCI) results in significant loss of function below the level of injury, often leading to restricted participation in community exercise programs. To overcome commonly experienced barriers to these programs, innovations in technology hold promise for remotely delivering safe and effective bouts of exercise in the home.ObjectiveTo test the feasibility of a remotely delivered home exercise program for individuals with SCI as determined by (1) implementation of the intervention in the home; (2) exploration of the potential intervention effects on aerobic fitness, physical activity behavior, and subjective well-being; and (3) acceptability of the program through participant self-report.MethodsFour adults with SCI (mean age 43.5 [SD 5.3] years; 3 males, 1 female; postinjury 25.8 [SD 4.3] years) completed a mixed-methods sequential design with two phases: an 8-week intervention followed by a 3-week nonintervention period. The intervention was a remotely delivered aerobic exercise training program (30-45 minutes, 3 times per week). Instrumentation included an upper body ergometer, tablet, physiological monitor, and custom application that delivered video feed to a remote trainer and monitored and recorded exercise data in real time. Implementation outcomes included adherence, rescheduled sessions, minutes of moderate exercise, and successful recording of exercise data. Pre/post-outcomes included aerobic capacity (VO2 peak), the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD), the Satisfaction with Life Scale (SWLS), and the Quality of Life Index modified for spinal cord injury (QLI-SCI). Acceptability was determined by participant perceptions of the program features and impact, assessed via qualitative interview at the end of the nonintervention phase.ResultsParticipants completed all 24 intervention sessions with 100% adherence. Out of 96 scheduled training sessions for the four participants, only 8 (8%) were makeup sessions. The teleexercise system successfully recorded 85% of all exercise data. The exercise program was well tolerated by all participants. All participants described positive outcomes as a result of the intervention and stated that teleexercise circumvented commonly reported barriers to exercise participation. There were no reported adverse events and no dropouts.ConclusionA teleexercise system can be a safe and feasible option to deliver home-based exercise for persons with SCI. Participants responded favorably to the intervention and valued teleexercise for its ability to overcome common barriers to exercise. Study results are promising but warrant further investigation in a larger sample.

“…Of note, oxygen consumption exceeded maximal values achieved during the GXT test for all OBA modes. Subject 4 had the highest level of injury with impairments of both triceps muscles, resulting in low VO 2 peak values compared with women with similar SCI and training status (22). She was also prone to spastic contractions in response to OBA (noted by subject report and observations from the experimenters).…”
