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.

Outcome Measures

Primary Outcomes (1)

  • Berg Balance Scale (BBS)

    A widely used outcome measure of static standing balance function (Newstead et al., 2005), categorized under the 'Activity' subsection of ICF domain. BBS scores range from 0 to 56 (the higher, the better). The change in BBS scores from baseline to 4 weeks post-training will be the primary endpoint.

    Baseline, post 4-week training, 2-month follow-up

Secondary Outcomes (11)

  • Functional Gait Assessment (FGA)

    Baseline, post 4-week training, and 2-month follow-up

  • Mini Balance Evaluation Systems Test (MBT)

    Baseline, post 4-week training, and 2-month follow-up

  • Trunk Impairment Scale (TIS)

    Baseline, post 4-week training, and 2-month follow-up

  • Center of Pressure (COP) Displacement

    Baseline, post 4-week training, and 2-month follow-up

  • TMS-evoked EEG Potentials (TEP)

    Baseline, post 4-week training, and 2-month follow-up

  • +6 more secondary outcomes

Study Arms (3)

RBT + Active HD-tDCS Group

EXPERIMENTAL

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.

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

RBT + Sham HD-tDCS Group

SHAM COMPARATOR

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.

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

SOC Control Group

OTHER

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

Other: Standard of Care Balance Training

Interventions

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.

RBT + Active HD-tDCS GroupRBT + Sham HD-tDCS Group

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