Study Details

Brief summary:

Our proposed study, \"NEUROBALANCE,\" aims to evaluate the effectiveness of a combined intervention involving robotic balance training and noninvasive brain stimulation in improving balance functions in individuals with chronic traumatic brain injury (TBI). The study will recruit 45 participants who have had a TBI for over six months and experience persistent balance deficits. Participants will be randomized into three groups: (1) robotic balance training with active brain stimulation, (2) robotic balance training with sham brain stimulation, and (3) standard-of-care rehabilitation.

The study will involve 12 training sessions over four weeks, with assessments conducted at baseline, post-training, and two months post-training to evaluate balance recovery and retention. The primary focus is understanding how this intervention affects brain and muscle activity during balance tasks and how these changes translate into functional improvements in clinical outcome measures of balance function. Additionally, participant feedback on brain stimulation and exercise engagement will be collected to inform future studies.

This research is particularly relevant to military service members, as TBI and balance impairments are common among this population. The findings may guide the development of personalized training protocols and contribute to broader rehabilitation strategies.

Exclusion Criteria:

1. Currently undergoing any regular physical therapy program or research studies focusing on balance functions.
2. Having a stroke or a penetrating TBI.
3. Affected by the peripheral nerve injury, neuromuscular conditions, or orthopedic issues of lower limbs before TBI, or have any persistent pain or difficulty maintaining blood pressure while upright.
4. Have a scalp or skin condition (e.g., psoriasis or eczema) on the scalp near the stimulation site.
5. Severe visual impairment (e.g., spatial neglect) or hearing problems may affect study compliance.
6. Any other neurological injury or psychiatric conditions (e.g., severe anxiety or schizophrenia, etc.)
7. Not being pregnant or thinking of becoming pregnant during the study period.

Interventions and Outcome Measures

Arms

experimental: RBT + Active HD-tDCS Group

Participants will engage in balance and postural control training on a robotic balance platform called Hunova (Movendo, Italy). Before balance training, the current intensity of 2 mA will be delivered to the leg motor area identified using neuronavigated transcranial magnetic stimulation, and the stimulation will be turned ON for 20 minutes.

sham comparator: RBT + Sham HD-tDCS Group

Participants will engage in balance and postural control training on a robotic balance platform called Hunova (Movendo, Italy). Before balance training, the current intensity of 2 mA will be delivered to the leg motor area identified using neuronavigated transcranial magnetic stimulation, and the stimulation will be turned ON transiently for 30 s, to provide a sensation of stimulation.

other: SOC Control Group

The SOC control group participants will perform conventional physical therapy exercises delivered by a trained PT.

Interventions

Combined (Robotic balance training and high-definition transcranial direct current stimulation)

The robotic platform will train the participants to maintain dynamic balance in the sagittal and the transverse planes (mediolateral and anterior-posterior directions) and engage in core stability and trunk control with seated balance exercises. In addition, high-definition transcranial direct current stimulation (HD-tDCS) will be used as an adjuvant to robotic balance training by priming the corticospinal circuits.

Standard of Care Balance Training

Participants in this group will receive a standard-of-care balance training administered by the Physical therapist.

Primary outcome measure

  • Berg Balance Scale (BBS) [ Time Frame: Baseline, post 4-week training, 2-month follow-up ]
