Suspension therapy involves supporting parts of the body in slings and ropes fixed above to increase range of motion and muscle strength. There are three main types of suspension therapy - axial, pendular, and vertical. Axial suspension circulates blood flow and strengthens muscles while allowing large joint movements. Pendular suspension increases muscle strength and endurance. Vertical suspension relaxes the suspended body part and improves range of motion. For the elbow joint, vertical suspension hangs the arm vertically while axial fixation attaches all ropes to a single point above the joint, allowing maximum movement on a flat plane. This functional therapy can be done sitting and helps patients with tasks like feeding and turning pages.
