Popis
Inclusion Criteria:
- Be an adult (i.e., ≥18 years old) with a SCI at T12 or above as individuals with a lower motor neuron condition are considered poor candidates for FES.
- Have a SCI rated as American Spinal Injury Association Impairment Scale A, B, C or D. If no recent (i.e., in past six months) AIS rating is available in the medical record, the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) exam (Rupp et al. 2021) will be completed by the research team.
- Be >1 year post-injury, in the case of traumatic SCI, or >1 year post-onset of neurological symptoms, in the case of a non-progressive, non-traumatic cause of SCI.
- Be able to attend 8 assessment sessions and three education sessions at the Lyndhurst Centre or Rumsey Cardiac Rehab, as well as 36 FES+HIIT@Home sessions and one education session on Microsoft Teams.
- Be ambulatory or use a manual wheelchair.
- Be able to don/doff electrodes independently or with support from a family member or other caregiver.
- Have physician clearance to participate in high intensity interval training (i.e., no contraindications to HIIT).
- Have an emergency contact who can be reached by the research team during FES+HIIT@Home sessions.
- Able to understand spoken English.
Exclusion Criteria:
- Presents with contraindications to FES (i.e. implanted electronic device, radiation in past six months, active deep vein thrombosis, pregnancy) (Houghton et al. 2010).
- Presents with cognitive deficits that would prevent independent use of an FES device.
- Has irritated and/or damaged skin in areas where the electrodes will be applied.
- Has a cardiovascular morbidity that would limit exercise tolerance, as identified through pre-intervention cardiorespiratory fitness testing (e.g., complex arrhythmias).
- Participant receives a Botox injection or begins a new therapy or exercise program during the first 20 weeks of the study (i.e., prior to the post-intervention assessments).

Experimentální: FES+HIIT@Home
Functional electrical stimulation combined with high intensity interval training at home
|
The FES+HIIT@Home intervention will be 16 weeks in duration.
During the first four weeks of the FES+HIIT@Home intervention (i.e., weeks 3-6), participants and caregivers who will be assisting will receive education and hands-on training with FES and HIIT exercises.
Each participant will receive a two-channel FES device to keep (i.e., Chattanooga® Continuum).
During weeks 7-18, participants will complete 36 online, group-based FES+HIIT@Home sessions (i.e., three 1-hour sessions/week for 12 weeks) that are led by trainers over Microsoft Teams.
Sessions will include warm-up exercises (10 minutes), three task-specific exercises (15 minutes/exercise) and cool-down exercises (5 minutes).
Each task-specific exercise will be performed in 30-second "all out" bouts with a 1.5-minute rest after each bout.

Function for participants unable to stand
Časové okno: From enrollment to the end of the 12-week follow-up at 34 weeks
|
Function will be assessed with the Function in Sitting Test (FIST-SCI) for participants unable to stand.
The FIST-SCI assesses postural control during functional sitting activities.
Items are rated on the amount of assistance required to accomplish each task on a 5-point scale of 0 (complete assistance - patient cannot perform the task at all) to 4 (independent - patient completely autonomous in performing the task).
Scores can be summed for a total score ranging from 0 to 56.

Function for participants able to stand
Časové okno: From enrollment until the end of the study at 34 weeks
|
Function will be assessed with the mini-Balance Evaluation Systems Test (mini-BESTest) for participants who are able to stand.
The mini-BESTest assesses a variety of functional activities in standing and walking.
The Mini BESTest is scored on a 3-level ordinal scale (0 to 2).
Scores can be summed for a total score between 0 and 28.

Muscle Strength
Časové okno: From enrollment until the end of the study at 34 weeks
|
Isometric strength of the trunk, upper limb and lower limb muscles will be evaluated with manual muscle testing (MMT) and/or hand-held dynamometry.
Testing positions will be standardized, following guidelines of the ISNCSCI, as appropriate, and strength scored on a 0 to 5 scale.
Muscles with a MMT score of ≥4 will also be assessed with hand-held dynamometry, which is a valid assessment method that has greater sensitivity to detect changes in the strength of stronger muscles.
Three peak force values will be collected per muscle group and the mean value normalized by body weight.

Penn Spasm Frequency Scale
Časové okno: From enrollment until the end of the study at 34 weeks
|
The Penn Spasm Frequency Scale is a valid and reliable self-report measure that evaluates an individual's perception of spasticity frequency (on a 5-point scale from 0 (no spasms) to 4 (spontaneous spasms occurring ≥10 times/hour)) and severity (on a 3-point scale from 1 (mild) to 3 (severe)).
A spasm severity rating will not be provided if spasm frequency is 0.

Spinal Cord Assessment Tool for Spastic Reflexes
Časové okno: From enrollment until the end of the study at 34 weeks
|
The Spinal Cord Assessment Tool for Spastic Reflexes is a short clinical exam of three spastic motor behaviors in the lower limb of individuals with SCI: clonus, flexor spasms and extensor spasms.
The reactions observed for each motor behavior will be rated on a 4-point ordinal scale and summed for a total score (/9).

Časové okno: From enrollment until the end of the study at 34 weeks
|
Exercise self-efficacy will be assessed with the SCI Exercise Self-efficacy Scale, which assesses confidence in performing exercise.
Participants will rate their confidence, on a scale from 1 (not always true) to 4 (always true), for ten statements related to carrying out regular exercise and physical activity.
Reponses are summed for a total score (/40).

Arterial stiffness
Časové okno: From enrollment until the end of the study at 34 weeks
|
Pulse wave velocity (PWV, m/s) will be obtained between the common carotid and common femoral arteries (cfPWV).
cfPWV (m/sec) will be calculated using the equation: (0.8 × D)÷Δt, where D is the distance between measurement sites and Δt is the pulse transit time.
