About this study

Official title: Effects of Gait Training Strategies and Noninvasive Stimulation on Neurophysiology and Walking Performance in Able-Bodied Adults- A Preliminary Study

This study is being done to answer the question: What are the effects of electrical stimulation and stepping practice on connections between the brain and muscles? The long-term goal of this project is to develop novel, effective, and personalized rehabilitation protocols founded on an understanding of neurobiological mechanisms that combine electrical stimulation with gait training to improve gait performance in older adults and stroke survivors.

The rationale of this project is to explore and generate preliminary data regarding how electrical stimulation-based strategies modulate cortical and spinal circuits in able-bodied individuals.

Read more

The researchers will evaluate the effects of short treadmill walking bouts or single gait training sessions with and without electrical stimulation on somatosensory, spinal-reflex, corticospinal circuit neurophysiology, and/or gait performance.

The study will provide important preliminary and normative data that can explain how brain circuits change with stimulation or stepping practice and inform future rehabilitation studies on patients. The study population is able-bodied individuals.

Read the detailed description

This study is being done to determine the effects of electrical stimulation and walking practice on connections between the brain and muscles.

This study consists of 1-5 study visits lasting up to 5 hours each. Participants will complete stepping training with or without electrical stimulation delivered to their leg muscles; noninvasive stimulation will be delivered to the participants' brain or nerves in the leg to measure the strength of connections within their brain and between their brain / spinal cord and their muscles.

The number of sessions for each participant will depend on whether the same participant completes only 1 or more than 1 study aim.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Gait TrainingOther

    Gait training: One or multiple short bouts of stepping practice on a treadmill at self-selected or fast speeds will be delivered without FES.

  • Functional electrical stimulation (FES)Device

    Also called FES

    Electrical stimulation involving the parameters and settings proposed here is commonly used in clinical practice and research for pain relief and other applications also referred to as neuromuscular or transcutaneous electrical nerve stimulation. The FES will be delivered using the UDel Stimulator, a custom-designed FES system from the University of Delaware FES lab.

    Researchers will use a customized, real-time system to control the stimulator and deliver stimulation during appropriate phases of the gait cycle. Stimulation will be delivered to the ankle dorsiflexors when the subject's foot is in the air (swing phase). Stimulation will be delivered to the ankle plantarflexors during the terminal stance phase of gait. 30-Hz variable frequency stimulation trains will be delivered during gait.

  • Peripheral electrical stimulation paired with cortical magnetic stimulation pulsesDevice

    The paired associative stimulation (PAS) will be conducted in a static posture (seated or standing), to evaluate effects on somatosensory, spinal-reflex, and/or corticospinal neurophysiology delivered with different stimulation parameters. One or multiple short bouts of stepping practice on a treadmill at self-selected or fast speeds may be completed before and/or after PAS to evaluate gait performance

Study groups in NCT06430164
Study groupRoleWhat they receive
Gait with functional electrical stimulationExperimentalParticipants will participate in 2 to 5 sessions over 2-8 weeks. Each session will comprise gait or stepping practice on a treadmill with functional electrical stimulation, and non-invasive measurement of neural circuit excitability. Participants will complete multiple 30-second to 4-minute bouts of walking on the treadmill or overground at speeds ranging from self-selected to fast speeds (faster than comfortable self-selected speed), with rest breaks between bouts. For gait training, participants may complete up to six 6-minute bouts of walking with rest breaks between bouts (30-36 minutes walking).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Gait Performance

    Marker data will be collected using a 7-camera motion analysis system at 120 Hz (Vicon, Oxford, UK). During treadmill walking, ground reaction forces during the treadmill walking will be collected using a treadmill instrumented with two 6-component force platforms under each belt (Bertec, USA). Ground reaction forces will be evaluated using a force plate embedded within the lab floor (AMTI, USA).

    Measured: Pretest (up to 60 seconds), during test (up to 36 minutes), post-test (up to 60 seconds)

  2. Corticospinal excitability

    Corticospinal excitability will be assessed using a non-invasive technique called transcranial magnetic stimulation (TMS). TMS will be delivered using MagStim Stimulators with a double circular coil, custom-built double-cone, or batwing coil (Magstim Ltd, Wales, UK). Electrical activity from muscles in response to the TMS will be collected using surface EMG electrodes attached to muscles that play critical roles during walking (e.g., quadriceps femoris, tibialis anterior, soleus, gastrocnemius, hamstrings, etc.). In addition, EMG signals may be recorded from a couple of upper extremity muscles (e.g., first dorsal interosseus, flexor digitorum indicis) to be used as a control.

    Measured: Pretest (up to 60 seconds), during test (up to 36 minutes), post-test (up to 60 seconds)

  3. Spinal circuit excitability

    Spinal excitability may be assessed using peripheral electrical stimulation delivered to the nerves innervating the ankle muscles. The methods for electrical stimulation are similar to those used for delivering functional electrical stimulation except that the subjects are seated and the stimulation is used to obtain outcome measures assessing spinal excitability. Muscles of interest are the soleus and medial gastrocnemius (calf muscles), and tibialis anterior (front of lower leg).

    EMG activity will be recorded while 50-60 electrical stimuli (short 1 ms square pulses, ranging in intensity from 1mA - 80 mA), 7-10 seconds apart, are delivered to the muscle. Researchers may also deliver 5-20 electrical stimulus pulses at intensities that elicit a percentage of the maximum reflex response.

    Measured: Pretest (up to 60 seconds), during test (up to 36 minutes), post-test (up to 60 seconds)
