About this study

Official title: A Pilot Study on the Cumulative Effects of Transcutaneous Spinal Cord Stimulation (tSCS) With Robotic Gait Training in Trunk Muscle Activity and Walking Index in Chronic Spinal Cord Injury

This study is aimed to evaluate whether transcutaneous spinal cord stimulation (tSCS) can augment robotic gait training (RGT) to improve functional mobility in participants with chronic spinal cord injuries. It also evaluate the impact of the tSCS+RGT on health-related quality of life (HRQOL), compared to RGT alone.

This is a prospective single-arm crossover study in participants with incomplete chronic traumatic spinal cord injury. 6 subjects with paraplegia and 6 subjects with tetraplegia will be recruited. The intervention includes Phase 1 of training which consists of 16 sessions of robotic gait training (RGT) + conventional physiotherapy in 8-10 weeks, and Phase 2 of training which consists of 16 sessions of RGT training + tSCS + conventional physiotherapy in 8-10 weeks.

Outcome measures including mobility function assessment and neuromuscular assessment will be collected at Baseline, Post-Phase 1 and Post-Phase 2. A satisfaction survey on the intervention "RGT training + tSCS + conventional physiotherapy" will be performed at week-18 assessment.

This study is aimed to evaluate whether transcutaneous spinal cord stimulation (tSCS) can augment robotic gait training (RGT) to improve functional mobility in participants with chronic paraplegia. It also evaluate the impact of the tSCS+RGT on health-related quality of life (HRQOL), compared to RGT alone.

This is a prospective single-arm crossover study in participants with incomplete chronic traumatic spinal cord injury. 6 subjects with paraplegia and 6 subjects with tetraplegia will be recruited. Once subject is identified to be eligible for the study and is agreeable to participate into the study, he/she will undergo Phase 1 of training which consists of 16 sessions of robotic gait training (RGT) + conventional physiotherapy in 8-10 weeks. After a 1-week washout period, subject will undergo Phase 2 of training which consists of 16 sessions of RGT training + tSCS + conventional physiotherapy in 8-10 weeks.

Subject will walk with EksoGT for gait training during RGT training. Components of conventional physiotherapy will include lower limb ergometry and strength training as prescribed by the attending physiotherapist based on their assessment. During tSCS, two surface electrodes will be positioned in between the vertebral processes located generally one vertebral segment rostral and one vertebral segment caudal to the site of injury. Reference/Ground electrodes placed over the ASIS. It will be on biphasic mode with an overlap frequency of 10kHz, Burst Frequency of 30Hz, Pulse width of 1ms. Stimulation intensity ranges from 5-100 mA and will be adjusted according to the patient's response. The tSCS stimulation duration for each session will be 45 minutes in conjunction with the RGT training

Outcome measures including mobility function assessment and neuromuscular assessment will be collected at Baseline (within 1 week before the starting of Phase 1 of training), Post-Phase 1 (within 1 week after Phase 1 of training) and Post-Phase 2 (within 1 week after Phase 2 of training).

A satisfaction survey on the intervention "RGT training + tSCS + conventional physiotherapy" will be performed at week-18 assessment.

  4. Modified Tardieu Scale

    Modified Tardieu Scale is to measure if there is spasticity present in a person's muscle and its response to movement. It will be measured for Quadriceps, Hamstrings, Gastrocnemius. A large difference between R1 and R2 suggests a large dynamic component with a greater capacity for change or improvement. A small difference between R1 and R2 suggests a predominantly fixed contracture in the muscle with a poorer capacity for change

Questions about this trial

What is this clinical trial studying?

A study testing RGT+ tSCS + conventional physiotherap and RGT+ conventional physiotherapy in people with Spinal Cord Injury, run by National University Hospital, Singapore at 1 site in Singapore.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 23 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Gobinathan Chandran, MBBS ((65) 94575924, Gobinathan_CHANDRAN@nuhs.edu.sg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Spinal Cord Injury - Trunk Control Test (SCI-TCT) (time frame: Week 0). The study lists 15 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Feb 2026.
