If a patient is undergoing treatment for motion sensitivity due to asymmetrical vestibular function, how many movements should be included in the initial home exercise program?

Including four exercises in the initial home exercise program for a patient with motion sensitivity due to asymmetrical vestibular function is appropriate because it strikes a balance between providing a sufficient range of stimulation to the vestibular system without overwhelming the patient.

The goal of vestibular rehabilitation is to gradually expose the patient to movements that promote adaptation and compensation for the asymmetry in vestibular function. Four exercises can cover different movement planes and types, allowing the patient to build tolerance and improve their vestibular processing without excessive strain. This moderate number also provides the opportunity for the patient to practice and master each exercise, promoting better adherence and effectiveness of the rehabilitation process. Additionally, it allows for progressive difficulty to be introduced as the patient progresses, with the option to increase the number of exercises or their complexity over time.

Starting with fewer exercises, such as two, may not provide enough variety or challenge for effective therapy, while six or eight exercises could lead to fatigue or frustration, which may hinder the patient's ability to perform them consistently. Thus, four exercises are optimal for beginning a structured and manageable home exercise program.
