Active stress, muscular contractions and joint motion allow collagen to be:

In the accompanying O2 dissociation curve, curve A represents myoglobin which is found in the muscle and has a higher affinity for O2 than hemoglobin. Myoglobin is initially 100% saturated at:

You have been delegated the intervention of stretching for a patient who sustained multiple trauma. The patient would be expected to gain the most joint motion during which of the following phases?

You are treating a patient with osteoarthritis in the knee. They “tweaked” it on the dance floor during a Mardi Gras ball. They have been resting it and are now in the subacute stage of healing. You would like to initiate isometric exercises to target muscles that surround the knee. The best position to place this patient to begin isometrics is

Following immobilization, which of the following techniques can reverse bone loss?  Vertical loading Passive exercise Resistive exercise Horizontal loading

Signs of hardware loosening include which of the following?

Nonoperative interventions for articular cartilage injury include: 

Provide an exercise of your choosing that would strengthen any muscle of the shoulder, hip, knee, or ankle. Progress this exercise from the acute phase to the return to function phase. Explain your progression.            5 points: progression is inclusive of all steps suggested in Kisner and Colby. Explanation of progression is comprehensive and easy to visualize the progression 4 points: progression is well thought out. Excludes 1-2 steps included in Kisner and Colby’s suggestions. Explanation of progression is suitable and moderately easy to visualize. 3 points: progression is acceptable but misses more than 2 steps included in Kisner and Colby’s suggestions. Explanation of progression is organized but lacks balance. 2 points: there is minimal progression noted. Explanation of progression is unorganized and difficult to visualize a patient progressing through the steps. 1 points: poorly progressed. Exercises get off track from the initiation in the acute phase. 

Bone remodeling is a lifelong activity! The type of law that states “skeletal transformation is dependent on physiologic loads or stresses” is known as 

You are treating a patient who suffered a grade 2 ankle sprain. They are currently in the chronic stage of healing. What should the muscle test grade be before discontinuing their crutches they have been using for protection?
