Hybrid high-intensity interval training using functional electrical stimulation leg cycling and arm ski ergometer for people with spinal cord injuries: a feasibility study

Table 1 Criteria to evaluate safety and feasibility

Outcome	Stop, do not continue	Continue	Continue with modification
Adverse events	More than 1 incidence of autonomic hyperreflexia or acute cardiac event during training	Less than or equal to 1 incidence of autonomic hyperreflexia or acute cardiac event during training
Participant acceptability	More than 50% of the participants rated experience during and after training higher than 3 (on a 1–7–point Likert scale, 1 = most acceptable)	Less than or equal to 50% of the participants rated experience during and after training higher than 3 (on a 1–7–point Likert scale, 1 = most acceptable)
Participants preference for training	More than 50% of the participants preferred continuous training to interval training	Less than or equal to 50% of the participants preferred continuous training to interval training
Shoulder pain	Individual WUSPI PC score ≥ 45 after the intervention	Individual WUSPI PC score < 45 after the intervention
Intensity			Less than 60% of participants reached the desired intensity of 90% peak watts
Attendance			Less than 60% of total training minutes were fulfilled.

Evaluation criteria, based on recommendations from Thabane, were set using a three-way system: stop, do not continue, continue without modifications, continue with modifications. The criteria were set pragmatically.
