Summary

Aim 1: Determine the relationships between muscle quality and balance performance as well as any association with fracture and fall history in older adults.

Muscle quality will be calculated from the information of muscle strength and body composition (strength/lean muscle mass). The investigators will compute the joint torque during functional activates using biomechanical data from the 3-D motion analysis, whereas the lean skeletal muscle mass will be determined by the bioelectrical impedance analysis (BIA). Clinical and functional assessments for balance performance will also be conducted. Fracture and fall history prior to the testing will be recorded retrospectively.

Aim 2: Identify the relationships between force usages during balance perturbation in older adults.

Lateral and forward/backward perturbation while walking will be used to elicit balance recovery responses. The degree of necessary joint force and how this relates to a person's functional capacity at specific joint levels will be determined by the torque demand to capacity ratio (DCR: task demands relative to strength capacity). The DCR provides a joint-specific unified scalar quantity representing the balance recovery demand normalized by the maximum muscle strength capacity of an individual. It would indicate whether a person can recover balance and to what extent of his/her maximum capacity is taxed.

Aim 3: Examine the effectiveness and long-term effects of a novel 2-month personalized strengthening and balance training program on improving balance performance in older adults.

Personalized strengthening and balance training exercise will be personalized based on the results of biomechanical assessments, using the Modular Interactive Tiles System (MITS) and split-belt balance perturbation instrumented treadmill. The exercise group will receive training 2 times a week for 2 months and the age-matched control group will maintain their usual daily life activities. All assessments will be performed at baseline, and 1 week after training. Follow-up telephone interviews will be conducted at 6, 9, and 12 months following the training period.
