Study Summary

This trial is testing whether a reflex training system can change the size of a reflex in people with chronic incomplete SCI. 25 participants are needed, and the study will last for 6 months with 45 visits.

Who is the study for?
This trial is for individuals with chronic incomplete spinal cord injury who can walk at least 10 meters, have leg spasticity, and are medically stable. They must be able to consent and not expect medication changes during the study. Excluded are those with unstable health, cognitive impairments, other neurological conditions, daily use of certain electrical stimulation devices, motoneuron injuries, serious heart issues, inability to test lower limb mobility or weight bearing, recent deep vein thrombosis or pregnancy.Check my eligibility
What is being tested?
The trial tests a reflex training system designed to reduce the size of targeted muscle reflexes in people with spinal cord injuries. Participants will undergo about 45 sessions over six months to see if this method can help manage spasticity in their legs by conditioning their spinal reflexes.See study design
What are the potential side effects?
While specific side effects aren't listed for this type of non-drug intervention, participants might experience discomfort or fatigue from repeated testing sessions. There may also be potential risks associated with any physical therapy-like activities such as muscle soreness.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Change in reflex activity as measured by the H-reflex amplitude (mV) in response to nerve stimulation
Change in walking distance (meters) as measured by the 6-minute walk test
Change in walking speed (m/s) as measured by the 10-meter Walk Test (10MWT)
Secondary outcome measures
Change in balance as measured by Berg Balance Scale
Change in basic functional independence as measured by the Spinal Cord Independence Measure (SCIM III)
Change in dynamic and static muscle length and joint range of motion (ROM) as measured by Tardieu Scale

Experimental Treatment
Group I: Validation of the new training systemExperimental Treatment1 Intervention
The researchers will measure changes in H-reflex size achieved with the use of the new system and compare these measures with the existing results in 25 spastic individuals with chronic incomplete SCI. Each participant completes 6 baseline sessions and 30 conditioning sessions. In the 30 conditioning sessions, the soleus H-reflex will be down-conditioned to decrease the activity of the hyperactive spinal stretch reflex pathway in people with spasticity that is characterized by exaggerated reflex activity. It is anticipated that the magnitude of reflex change obtained with the use of the new system would be greater or at least the same as the bench-marked values from the previous studies that used the old prototype reflex conditioning system.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is enrollment for this investigation actively open?

"The information on clinicialtrials.gov reveals that patient recruitment for this particular trial has been paused since May 11th 2022, when it was last updated. Although no more participants are being accepted now, over one thousand other studies remain open to new enrollees."

What objectives is this clinical experiment attempting to fulfill?

"The primary outcome of this investigation is the alteration in walking speed (m/s) as determined by the 10-meter Walk Test (10MWT), assessed at baseline, after conclusion of intervention sessions (~10 weeks), 1 month and 3 months post-intervention. Secondary outcomes include change in spasticity level on the Modified Ashworth Scale (MAS; 0 to 4 scale where a lower score indicates reduced spasticity); balance improvement measured through Berg Balance Scale (0 to 56 scale with increasing scores signifying better equilibrium and decreased risk of falls); together with variation in basic functional independence per Spinal cord Independence Measure III (SCIM"
