Which of the following describes a manual option of traction?

A manual option of traction is characterized by a therapist applying force directly to the patient's body to create separation in the joints or spinal structures. This hands-on approach allows the therapist to adjust the amount and direction of force according to the specific needs of the patient in real-time. It also enables immediate feedback from the patient's responses, enhancing both safety and effectiveness during treatment.

In contrast, the other options involve mechanisms that do not align with the definition of manual traction. Using an electric motor represents a more automated approach, while requiring patient cooperation with a machine indicates reliance on devices or technology rather than hands-on physical manipulation. The last option, involving no external assistance, might suggest a scenario where traction is applied without professional intervention, which is not typically safe or effective. Thus, the definition of manual traction is most accurately reflected by the therapist’s role in applying force.
