Physical Therapy Assistant Practice Exam

In which technique does one initiate treatment with passive movement before transitioning to active-assistive movements?

1. Rhythmic initiation

2. Successive induction

3. Reciprocal inhibition

4. Irradiation

The correct answer is: Successive induction

The technique that begins with passive movement and transitions to active-assistive movements is rhythmic initiation. This method involves a progression starting from passive movement, where the therapist guides the motion, to active-assistive movement, where the patient begins to contribute to the movement with support from the therapist. The purpose of this technique is to help the patient learn the movement pattern and enhance their motor control, promoting better function and aiding rehabilitation. Successive induction, on the other hand, refers to the physiological phenomenon where one muscle group is activated, leading to the facilitation of the opposing group’s activation, which is not related to the initiation of treatment with passive movement. Reciprocal inhibition involves the simultaneous contraction of one muscle and the relaxation of its antagonist, which does not align with the described technique. Irradiation is related to the spread of muscle activity from strong to weak muscles but does not specifically pertain to starting with passive movements. Understanding rhythmic initiation allows therapists to effectively guide patients through the early stages of rehabilitation, facilitating a smoother transition from passive support to independent movement. This method can be particularly beneficial in cases where patients have limited mobility or are learning new motor patterns post-injury or surgery.
