Study type
Interventional
Description of intervention(s) / exposure
Upper limb rehabilitation will be provided in combination with transcutaneous spinal cord neuromodulation (TESCoN), for at least 2 hours per day, 5 days per week for 4 weeks.
The rehabilitation will be provided by a physiotherapist experienced in the management of SCI and will be tailored to the motor capacity of each participant. It may include:
- strengthening exercises (e.g. resisted movements using weights or manual resistance as in proprioceptive neuromuscular facilitation patterns)
- assisted and/or resisted movements aimed at facilitating and strengthening voluntary trunk muscle activity in lying (supine. prone, side-lying) or sitting. Practice of functional tasks that involve movement over and outside of the base of support will also be included.
- intensive training of gross and fine motor skill tasks (e.g. reaching for and manipulating objects of different size, weight and texture)
- playing computer games that encourage hand movements
TESCoN, provided concurrently with upper limb rehabilitation will be delivered via electrodes placed midline between the spinous processes of the C3-C4 and C6-C7 vertebrae using a stimulator (SpineX Inc, Ca, USA). Biphasic rectangular 1ms impulses will be applied, with a frequency of 30Hz, filled with a carrier frequency of 10Hz. This stimulation permits currents of up to 80-120 mA to be delivered to the skin without discomfort. Stimulation will be introduced gradually and adjusted according to participant comfort. TESCoN will be delivered throughout the rehabilitation sessions, but may be turned off for short periods to assess the participant's ability to perform voluntary movements.
Adherence to the intervention will be monitored through daily attendance records.

24-hour blood pressure monitoring will be performed using a Card(X)plore monitor (Meditech, Budapest Hungary) with an appropriately sized cuff, worn by participants for a 24-hour period. This will be applied by the project assessor at the time of the assessment visits and removed by participants the next day. Measurements will be taken half-hourly during the day (0600–2200 hours) and hourly at night (2200–0600 hours) and analysed according to mean day (1000-2000 hours) and night (0000-0600 hours) values for systolic and diastolic BP.

3-day urinary output measurement will involve recording the time that participants void or empty their catheter bag on waking on the first day (Day 1) and then recording urine volumes and times at each void or each time the catheter bag is emptied, until and including the measurement on first waking on Day 4. A measuring jug will be provided for measurement of voided urine or urine emptied from the catheter bag. Day and night rates or urine output will be calculated to determine whether the whether the rate of urine output at night was significantly different from the rate during the day.

Other design features
Flexible adaptive Bayesian optimal phase IIa (BOP2) basket design, with 4 strata of participants to be recruited:
1. Subacute spinal cord injury (SCI) with motor complete (AIS grade A or B) tetraplegia
2. Subacute SCI with incomplete (AIS grade C or D) tetraplegia
3. Chronic SCI with motor complete (AIS grade A or B) tetraplegia
4. Chronic SCI with incomplete (AIS grade C or D) tetraplegia

Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
The sample size for each individual stratum has been calculated using the BOP2 Program (PID: 960; Version: V1.3.17.0). Optimal stopping boundaries have been pre-specified and the criteria for the combined efficacy/safety primary outcome determined on the basis of published data. The design allows the study to satisfy conventional frequentist power constraints, i.e., to yield power of 0.8 using false positive threshold of 0.05, with 20 participants (cohort size of 5) per stratum.

Individual interventions will be analysed in accordance with pre-specified rules to be declared promising or otherwise. Observed proportions of participants with positive primary outcome (composite of efficacy and lack of safety concerns) in each stratum will be reported, together with respective 95% confidence intervals. Longitudinal analyses of individual secondary and exploratory outcomes collected to inform the design of subsequent Phase IIb/III trials will be investigated using mixed effect regression modelling with individual participants treated as random effects.

Summary
Brief summary
This project addresses a significant unmet need: recovery of arm and hand function in people with tetraplegia (loss of use of the arms and legs). This issue is ranked by survivors as being of the highest importance, more important than the ability to walk. A novel non-invasive method of spinal cord stimulation (transcutaneous spinal cord neuromodulation – TESCoN) will be trialled for the first time in Australia, and in both subacute and chronic tetraplegia. Electrodes on the skin at the back of the neck will deliver a unique form of stimulation to the spinal cord without causing discomfort. This will modulate (alter the activity of) spared but non-functional pathways as well as the spinal circuitry below the injury level. When combined with intensive rehabilitation of the arm and hand, TESCoN leads to altered connections within the spinal cord, resulting in improved function. TESCoN enhances the effect of intensive rehabilitation and is not a replacement for it. This study will be an open-label trial using an adaptive design, with a combined efficacy and safety endpoint and clear rules for stopping the trial if the intervention is shown to be ineffective and/or unsafe. TESCoN is expected to lead to improvements in function that are superior to those obtained with current best practice rehabilitation. Such recovery of function may have a substantial impact on independence, potential for employment, and quality of life..
