When would a therapist utilize AR-ROM (active-resisted)?

The utilization of active-resisted range of motion (AR-ROM) by a therapist is most relevant during strength testing of contractile tissues. This approach involves having the patient actively engage their muscles while the therapist provides resistance, which helps in evaluating the strength and function of specific muscle groups.

This method allows the therapist to assess the patient's ability to generate force against resistance, providing valuable information regarding muscle performance and identifying any deficiencies or imbalances. By employing AR-ROM, the therapist can ensure that contractile tissues are not only functioning but are also capable of generating the necessary strength required for various movements and activities.

In contrast, other options do not accurately reflect the purpose of AR-ROM. Passive motion exercises focus on facilitating movement through someone else’s assistance and do not engage the patient’s own muscle activity. Relaxation techniques typically involve calming practices that do not incorporate resistance in any form. Assessing joint integrity usually involves observing stability and range of motion rather than actively testing muscle strength against resistance.
