Summary
Single-site transcutaneous spinal stimulation (TSS) is more effective than multi-site TSS for activating leg muscles and generating force in healthy individuals. Understanding segmental effects is crucial for optimizing TSS applications.
Area of Science:
- Neuroscience
- Rehabilitation Medicine
- Motor Control
Background:
- Transcutaneous spinal stimulation (TSS) aids rehabilitation in neurological deficits.
- Precise stimulation localization is critical for targeted functional enhancement with TSS.
Purpose of the Study:
- To compare single-site versus simultaneous multi-site lumbar spinal cord stimulation.
- To determine the optimal method for motor pool recruitment and leg extensor force generation.
Main Methods:
- Neurologically intact individuals received TSS at T10-T11, T11-L1, L1-L2, and L1-L2 intervertebral spaces individually and simultaneously.
- Spinally evoked motor potentials and lower limb muscle forces were measured at motor threshold intensity.
Main Results:
- Motor pool recruitment followed topographical rostro-caudal organization.
- Single-site stimulation (except T10-T11) yielded greater motor responses and forces (knee extension, plantarflexion) than multi-site stimulation.
Conclusions:
- Multi-site TSS reduced both motor response and force generation compared to single-site stimulation.
- Segmental effects of TSS must be considered for effective multi-site application.
