30. If an adverse response is encountered when a patient is progressed to a higher intensity level and the adverse effect persists to the next scheduled training session, the therapist should: a. Continue the training at the new intensity level regard- less of the adverse responses. b. Progress the training to a higher intensity to resolve the adverse effect. c. Instruct the patient to quit the rehabilitation program and start home exercise on his or her own. d. Wait until the adverse effects are resolved and continue the training at a lower level to avoid recurrence of the adverse effects. 31. To initiate running training after ACL reconstruction, the quadriceps strength index should be: a. 50%. b. 70%. c. 80%. d. 90%. 32. The decision for allowing patients with ACL reconstruction to return to sports should be based on which of the following criteria: a. Time from the surgery to ensure that graft healing took place. b. Resolution of impairments. c. Strength and hop testing scores. d. All of the above. 33. Athletes show readiness to return to sports after ACL reconstruction when they: a. Have completed their rehabilitation program and show less than 10% deficit in a battery of tests incorporating performance-based and patient-reported outcomes. b. Demonstrate less than 10% deficits in a battery of tests incorporating performance-based and patient-reported outcomes and are at least 9 months post-surgery. c. Are at least 9 months post-surgery. d. Are cleared by the physician. 34. Which of the following graft types has the highest failure rate after ACL reconstruction surgery? a. Semitendinosus-gracilis autograft. b. Quadriceps tendon autograft. c. Bone-patella tendon-bone autograft. d. Soft tissue allograft. 35. Athletes who do not return to either preinjury activity levels or return to sports are more likely to: a. Report a fear of reinjury. b. Have a high level of coach and team support.
23. A patient is classified as a potential noncoper if his or her: a. Effusion is graded as a trace. b. Single-legged crossover hop is >90%. c. GRS score is <60%. d. Quadriceps index is <80%. 24. During roller board and platform perturbation training, patients are instructed on: a. Moving the roller board in the same direction of the force applied by the therapist. b. Overcoming the applied force to the roller board. c. Developing selective muscle contraction during the training. d. Co-contracting all muscles that cross the knee joint. 25. ACL reconstruction is not recommended until: a. The GRS score is >60%. b. Pain is rated at 0/10 on a visual analogue scale. c. The patient has returned to preinjury activity levels. d. The quadriceps index is ≥90%.. 26. Patella mobilization, stationary cycling, and prone hangs and bag hangs with weights are beneficial for: a. Improving quadriceps strength. b. Managing joint effusion. c. Improving knee joint range of motion. d. Reducing pain. 27. The hamstrings strengthening exercises in patients with semitendinosus-gracilis autograft can be initiated: 28. To increase quadriceps strength using neuromuscular electrical stimulation (NMES) training, the amplitude of the electrical current should produce a quadriceps force to be equivalent to what percentage of maximum voluntary isometric contraction of the injured limb’s quadriceps muscle? a. 25%. b. 50%. c. 75%. d. 110%. 29. Non-weightbearing strengthening exercises of the quadriceps muscles should: a. Never be used after ACL reconstruction. b. Be initiated within the first 2 weeks after ACL reconstruc- tion from 0° to 45° knee flexion at maximal loads. c. Be performed in combination with weightbearing strengthening exercises. d. Only be performed after the ACL has completely healed. a. 1 week after ACL reconstruction surgery. b. 4 weeks after ACL reconstruction surgery. c. 8 weeks after ACL reconstruction surgery. d. 12 weeks after ACL reconstruction surgery.
c. Have greater intrinsic motivation. d. Exhibit increased self-efficacy.
