Charlie positions his right arm in slight flexion due to an old triceps tendon injury with resulting weakness. How could you facilitate contraction of the triceps muscle to improve extension and prevent contracture in Charlie’s right arm?
  1. Provide passive range of motion to Charlie’s right elbow.
  2. Provide quick stretch to Charlie’s biceps, followed by reaching forward for a cone.
  3. Provide quick stretch to Charlie’s triceps, followed by weight bearing on the right arm.
  4. Complete active range of motion exercises.
Explanation
Answer: C. To facilitate contraction of the triceps muscle to improve extension, you could provide quick stretch to Charlie’s triceps, and immediately follow the stretch with weight bearing on the right arm. The quick stretch causes the muscle fibers to fire and facilitates a quick contraction of the muscle. This response must be immediacy followed by activity addressing the motion the muscle creates, preferably with some resistance, if possible.
