Balance Deficits

This study will compare two exercise-based rehabilitation programs to improve balance and reduce fall risk in adults aged 45 years and older who have had at least one fall in the past year or have balance problems. Participants will be assigned to one of two groups: (1) a virtual reality (VR) exercise program using the PABLO system, or (2) a traditional physiotherapy program based on the Otago approach. Both programs will include balance training, strength/power exercises, aerobic activity, and flexibility. The program will last 12 weeks, with two supervised sessions per week (about 30 minutes each). Assessments will be completed at the start of the study and again after 12 weeks. The main outcomes include frailty status, number of falls, mobility (Timed Up and Go test), and balance (Berg Balance Scale). Additional outcomes include grip strength, quality of life (SF-12), and program adherence and safety. The study will help determine whether VR-based rehabilitation improves participation and outcomes compared with traditional physiotherapy.

The main aim of this study is to understand if an experimental vestibular implant system can improve balance performance. The system consists of a vestibular implant combined with a cochlear implant sound processor and programming software. The implant is designed to preserve hearing in the implanted ear. The vestibular implant is surgically placed under the skin just behind the ear in the mastoid bone and has an electrode that stimulates the vestibular nerve. A sound processor is worn behind the ear and powers the implant via the coil. The study will be conducted in adults with bilateral vestibulopathy (BVP) who have normal to severe hearing loss in the inner ear. The study participants will undergo a series of tests that include evaluations of their balance and hearing and self-reported questionnaires on their balance and general health.

Our proposed study, "NEUROBALANCE Stroke,"; aims to evaluate the effectiveness of a combined intervention involving robotic balance training and noninvasive brain stimulation in improving balance function and postural control in individuals with chronic stroke. The study will recruit 45 participants who have had a stroke at least 6 months before enrolment and experience persistent balance and gait 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 15 training sessions over 5 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. The findings may guide the development of personalized training protocols and contribute to broader rehabilitation strategies.

The goal of this study is to learn if manipulating the brain using magnets works to treat balance impairment, a major cause of falls, in older adults with balance problems. The technique to manipulate the brain using magnets is known as transcranial magnetic stimulation or TMS. The main questions this study aims to answer are: * How does TMS change communication between brain areas? * Does TMS improve balance ability in older adults with balance problems? Researchers will compare the TMS group to a placebo group to see if manipulating the brain using magnets works to treat balance impairment. Participants will: * Receive TMS or placebo stimulation for 4 weeks. * Visit the laboratory for checkups and tests 3 times.

This multi-center randomized trial (MCRT) will investigate the effectiveness of the VestAid application to provide equivalent or faster recovery from dizziness compared to standard-of-care delivery of vestibular rehabilitation exercises.
