Problem: A client recovering from a lumbar strain is attending a work hardening program. During the initial evaluation, the client was able to lift 20 pounds (9 kg) without reports of pain. During a therapy session, the client can only lift 15 pounds (6.8 kg) and reports a dull pain in the lumbar region. What action should the COTA take NEXT based on this session? Notify the OTR of the observed changes. Decrease the intensity of the therapy activities. Decrease the frequency of therapy sessions. Recommend a referral to a pain management clinic.
