FES-assisted Gait Intervention in People with Spinal Cord Injury - Pilot Study
- Conditions
- Spinal Cord Injuries
- Registration Number
- NCT05908175
- Lead Sponsor
- Stichting Reade
- Brief Summary
A spinal cord injury (SCI) disrupts the communication within the nervous system, leading to limitations in sensorimotor activities such as walking. Regular use of functional electrical stimulation (FES) can result in recovery of voluntary muscle control and muscle strength. Locomotor training with FES may be a promising method to improve gait function. The primary objective of this pilot study is to assess the feasibility and safety of an FES-assisted gait training intervention. Secondary objectives are to assess the effects of an FES-assisted gait training intervention on gait function.
- Detailed Description
A spinal cord injury (SCI) disrupts the communication within the nervous system, leading to limitations in sensorimotor activities, such as walking. These limitations are associated with muscle weakness, a disturbance of the reflex activity, and the inability or difficulty to recruit muscles below the lesion. Regular use of functional electrical stimulation (FES) can result in recovery of voluntary muscle control and muscle strength. Studies that investigated the effect of locomotor training on a treadmill with functional electrical stimulation and/or body weight support (BWS) show improved function of the lower limbs. FES-assisted gait therapy may be a promising method for improving gait function in individuals with an incomplete SCI. Therefore, this study will investigate if an FES-assisted gait (with BWS) is feasible and safe. This study will also investigfate if an FES-assisted gait can improve gait function in people with an incomplete SCI.
Primary objective of this pilot study is to assess the feasibility and safety of an FES-assisted gait training intervention. The secondary objectives are to assess the effects of an FES-assisted gait training intervention on gait function.

- Primary Outcome Measures
Name Time Method Incidence of (Serious) Adverse Events [Safety of the Intervention] Assessed during week 1 to 10 for each FES-assisted gait training session (2x week) and in week 0, week 11 and week 21 (during the pre-, post- and follow-up measurements) The total number of (serious) adverse events
Feasibility of the intervention Assessed during week 11 during the post-intervention measurement. Self-administered questionnaires about the training sessions, preceived effect, applicability of FES and the experience with walking with FES.
- Secondary Outcome Measures
Name Time Method Change in muscle activity Assessed before and after the 10-weeks FES-assisted gait training intervention (during week 0 and week 11) Surface EMG measurement during 10 meter walk test. Time of muscle activation and duration of muscle activity of the m. rectus femoris, m. vastus lateralis, m. semitendinosus, m. tibialis anterior, m. gastrocnemius medialis, m. soleus and m. peroneus longus
Change in step length Assessed before and after the 10-weeks FES-assisted gait training intervention (during week 0 and week 11) Step length left and right (cm) measured during 10 meter walk test with the interactive walkway (kinect)
Change in step width Assessed before and after the 10-weeks FES-assisted gait training intervention (during week 0 and week 11) Step width (cm) measured during 10 meter walk test with interactive walkway (kinect)
