This study investigates the use of translingual neurostimulation (TLNS) combined with physical therapy (PT) to treat chronic balance deficits in people who have experienced mild to moderate traumatic brain injury (mmTBI). TLNS involves stimulating cranial nerves via the tongue. Participants with a chronic balance deficit after mmTBI, who had plateaued in recovery after prior conventional PT, were enrolled in the study. They were randomized to receive PT plus either high-frequency pulse (HFP) or low-frequency pulse (LFP) TLNS. The study found that both HFP and LFP TLNS, when combined with targeted PT, led to significant improvements in balance and gait, as well as reductions in headaches, improved sleep quality and reduced fall frequency. The improvements occurred in participants who had plateaued on prior conventional physiotherapy.
TLNS combined with PT can lead to clinically meaningful improvements in balance and gait for individuals with chronic balance deficits after mmTBI.
The intervention can reduce the number of falls and the frequency of headaches in this population.
Participants also reported improved sleep quality with the treatment.
