What type of therapy uses weights, ropes, and pulleys to aid in healing?

The therapy that utilizes weights, ropes, and pulleys to assist in the healing process is traction. This method involves applying a pulling force to specific parts of the body, which helps to alleviate pain, relieve pressure on the spine, and improve mobility. Traction is often used for conditions affecting the spine, such as herniated disks or other forms of back pain, as it can help create space between vertebrae and promote healing.

The use of ropes and pulleys provides controlled traction, allowing therapists to adjust the amount of force applied based on the patient's individual needs. This approach is particularly beneficial for maintaining or restoring the alignment of the spine or joints.

In contrast, massage therapy focuses on manipulating the soft tissues of the body to promote relaxation and relieve tension, while hydrotherapy involves the use of water for therapeutic purposes, such as pain relief or rehabilitation exercises. Electrotherapy utilizes electrical currents for muscle stimulation, pain management, and promoting healing, which is a different technique altogether. Thus, traction stands out as the specific therapy that employs weights, ropes, and pulleys for healing purposes.
