• Falls represent a significant health risk in the elderly with
osteoporosis
– result in injuries that require medical attention

Sequelae of aging in musculoskeletal system
Changes in postural alignment -kyphosis Osteoporotic fractures
Shifts of center of mass position Increase demand of force capacity
Poor upright balance Fall and fracture
Passive bone
Active muscle
Sequelae of aging in motor control system
Osteoporosis Decline in bone mineral density
Sarcopenia Decline in muscle mass
Control coordination
Hypothetical Model for Effects of Aging on Upright Balance
Loss of error-compensation Adaptation ability decrease
Loss of lean skeletal muscle Muscle strength decrease
Loss of bone mass Vertebrae height decrease

Upright Balance
• Stability in upright position
– keeping the vertical projection of the whole body center
of mass within the base of support

Purpose
• To relieve pain
• To increase joint mobility
• To improve posture
• To investigate the immediate effects of stretching
exercise and myofascial release on kyphotic posture in
individuals with osteoporosis and osteopenia
