Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Linked study record
This study was a pilot study related to registration record ACTRN12622000145707. We commenced that study and collected data for 5 participants before it became clear that further refinement of the primary outcome measure was required and an ethics amendment was submitted for this. We therefore decided that these 5 participants would serve as a pilot and would be analysed separately from the participants who were enrolled after the ethics amendment.

Intervention/exposure
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 spinal cord injury (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)
- 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 the participant's tolerance. 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.
