Final answer:
When the physical therapist finds unexpected additional issues with range of motion and use of body parts, further assessments and modifications to the treatment plan may be necessary.
Step-by-step explanation:
When the physical therapist finds additional issues with range of motion and use of body parts that were not involved in surgery, it is unexpected and may require further assessment and modifications to the treatment plan. This can happen due to various factors such as compensatory movements or underlying conditions. The therapist may need to re-evaluate the patient's condition, reassess their range of motion, and propose additional exercises or techniques to address the new issues.
