Non-Invasive Cervical Spinal Stimulation and Respiratory Recovery After Spinal Cord Injury: A Randomized Controlled...

Area of Science:

• Neurology
• Pulmonology
• Rehabilitation Medicine

Background:

• Respiratory impairment is a major cause of death in spinal cord injury (SCI) patients.
• Cervical SCI (cSCI) significantly impairs breathing due to respiratory muscle paralysis.
• Transcutaneous electrical spinal cord stimulation (tSCS) shows promise for enhancing motor function and recovery.

Purpose of the Study:

• To investigate the efficacy of cervical tSCS in improving respiratory function in cSCI patients.
• To assess the impact of tSCS on respiratory muscle strength and lung capacity.
• To evaluate tSCS as a therapeutic strategy for respiratory complications in cSCI.

Main Methods:

• Randomized controlled trial with partial crossover design.
• Participants with cSCI received tSCS (30 Hz) at C3-C4 and C6-C7 spinal levels during occupational therapy for 8 days.
• Respiratory function assessed via maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), and spirometry.

Main Results:

• The tSCS group (n=15) showed significant improvements in MIP, MEP, and forced vital capacity (p < 0.05).
• The control group (n=11) exhibited no significant changes in respiratory function.
• Seven participants completed both tSCS and control phases.

Conclusions:

• Cervical tSCS can enhance respiratory function in individuals with cSCI.
• This stimulation may promote neuroplasticity and mitigate long-term respiratory issues.
• Further research with long-term protocols and larger cohorts is needed to confirm efficacy.
