Four postural modifications to prevent long-term bed rest complications and enhance stress response, promoting bone healing
✓ Upright training to prevent orthostatic hypotension
✓ Enhanced lower-limb circulation to accelerate wound healing
✓ Head-elevated supine position to facilitate airway secretion clearance 
✓ Improved bone tissue adaptability to mechanical stress

✓ Pulmonary infection control to improve cardiac function
✓ Wolff’s law application to promote bone healing and prevent bone density loss 
✓ Reduced local tissue pressure to prevent pressure ulcers
✓ Upright training for arousal therapy and care in coma patients
✓ Prevention of urinary tract infections and improvement of bladder function

Progressive loading to restore limb function
✓ Gradual reduction of muscle atrophy and restoration of normal muscle tension 
✓ Precise adjustment of tilt angle to achieve progressive loading training
