Improved gait speed in spastic paraplegia: a new modality

Area of Science:

• Rehabilitation Medicine
• Neurology
• Biomedical Engineering

Background:

• Gait disturbance in spastic paraplegia significantly impacts mobility, increases fall risk, and reduces quality of life.
• Current rehabilitation strategies for spastic paraplegia often focus on managing symptoms rather than directly improving gait parameters.

Purpose of the Study:

• To investigate the efficacy of electrical twitch obtaining intramuscular stimulation (ETOIMS) in improving gait speed and pattern in patients with spastic paraplegia.
• To assess the impact of ETOIMS on subjective symptoms such as pain and stiffness.

Main Methods:

• A prospective short-term cohort study involving 5 spastic paraplegia patients (spinal cord tumor, cervical myelitis, hereditary spastic paraplegia, spinal cord injury).
• ETOIMS applied to bilateral quadratus lumborum, multifidus, and gluteus medius muscles.
• Gait speed, gait pattern, and pain scores (visual analogue scale) were evaluated before and after a single ETOIMS session.

Main Results:

• All participants reported subjective improvements in walking stiffness and alleviation of lower back and gluteal pain.
• Significant improvements in gait speed were observed in four out of five patients (ranging from 6% to 57% increase).
• All patients demonstrated increased pelvic dissociation post-intervention, indicating improved gait pattern.

Conclusions:

• ETOIMS shows promise as an effective intervention for enhancing gait speed and stability in spastic paraplegia.
• The mechanism may involve muscle relaxation and pain alleviation in the lower back and gluteal regions.
• Further research with larger cohorts is warranted to confirm these findings and explore long-term effects.
