Ageing is associated with a loss of balance and mobility. This study was conducted to determine if the use of heat, vitamins alone or heat with vitamins could increase mobility and balance in adults with mobility impairments. Eighty adults in the age range between 55 and 64 were randomly divided into 4 different groups; low level continues heat (LLCH), vitamins (VT) alone, vitamins combined with heat (VT + H), and control group. Subjects were sedentary individuals that were not participating in any balance or walking exercises regularly and were not taking vitamins for at least 1 year. 4000 units vitamin D, 1000 units vitamin E, 300mg CoQ10, 600 mg Calcium, 1 tablet multivitamin were taken each day in the VT and VT + H groups. LLCH was applied with a dry chemical heat wrap, average temperature 42°C for 4 hours per day over the upper leg. The outcome was assessed through postural sway and tremor during standing, tremor, gait speed, symmetry, ground reaction force, and muscle activity during gait. All experimental groups showed significant improvement in balance and walking ability after 4 months of interventions (p < 0.05) but no significant changes were found in the control group. The difference between the control group and all other groups was significant (p < 0.05). The greatest improvements were found in VT + H group after 4 months. This is evidenced by better balance, less muscle tremor and faster and more stable gait, especially with the heat and vitamins used together. Heat and vitamins used together were synergistic.
