Final answer:
The initial OTA intervention should involve gentle Range Of Motion exercises to maintain joint mobility and muscle strength, as well as education on ergonomic adjustments for work tasks.
Step-by-step explanation:
An Occupational Therapy Assistant (OTA) using a biomechanical approach for a patient with a non-displaced distal radius fracture should prioritize interventions that target physical impairments to improve functional abilities. In the initial stages of healing, it is important to protect the fracture; hence, providing a dynamic splint would restrict necessary movement and might not be appropriate 24/7.
Therefore, the correct intervention should involve gentle Range Of Motion (ROM) exercises. These exercises will help maintain joint mobility and muscle strength around the fracture site, facilitating a quicker and more functional recovery. Additionally, the OTA should educate the patient on ergonomic adjustments and the use of adaptive equipment for job tasks to prevent further injury and facilitate return to work.
