Final answer:
In this scenario, the OT should evaluate the individual's specific needs and capabilities as the first step in an assistive technology intervention.
Step-by-step explanation:
In this scenario, the OT (Occupational Therapist) is performing an assistive technology intervention with an individual who demonstrates severely impaired motor performance. The first step the OT should take is to evaluate the individual's specific needs and capabilities. This assessment will help the OT determine the most appropriate assistive technology to address the individual's motor impairments. For example, if the individual has difficulty using their hands, the OT may consider recommending a device with a touch screen or voice-activated controls.
