Which component is NOT typically associated with traction devices?

Traction devices are primarily used to treat musculoskeletal conditions by applying a pulling force to a body part, usually to immobilize or realign bones and relieve pressure. Each of the other components plays an essential role in the functioning of these devices.

The traction unit generates the necessary force for the traction treatment, ensuring that the correct amount of pull is applied. The weight system is critical as it provides the necessary resistance to create the traction force. Harnesses or belts are used to secure the patient and maintain alignment during the treatment.

Electrodes, on the other hand, are generally associated with electrical stimulation therapies rather than mechanical traction. They are typically used in modalities like electrotherapy to help alleviate pain or promote healing through electrical impulses, which is not a function of traction devices. Therefore, the option that does not align with the fundamental components associated with traction devices is indeed electrodes.
