Mrs. Silver is a 58 yo female s/p Colles’ fracture of the (L) wrist. She states that she was casted for 6 weeks, and then her doctor told her to perform stretches to her (L) wrist to regain ROM. It has been 8 weeks since her cast was removed, and she continues to lack motion in the wrist. At her last visit, her physician added strengthening exercises, but she was concerned about her lack of range and decided to seek help.

Clinical Findings: Mrs. Silver demonstrates limited passive range of motion (PROM) in all directions, with flexion and ulnar deviation being most involved. Accessory motion testing of the radiocarpal joint shows hypomobility of joint gliding motions in all directions, with posterior and radial glides being most affected. Muscle strength is mildly limited.

Plan of Care: Mrs. Silver will receive joint mobilization techniques to improve joint gliding accessory motions. Hold stretching activities until accessory motion improves.

What is the rationale for this plan of care?

Movement and Biomechanics:

Perform a biceps curl with an object (weight, coffee cup, etc). Answer the following questions:

1. What type of lever are you using?
2. Diagram the work that is required by the biceps to move the object?
3. Create a mathematical formulation to justify your answer.

Put a golf ball. Answer the following questions:

1. Diagram the forces applied to the golf ball and it’s the journey.
2. Break down the phases of the activity that you performed. (this can be generic at this time, but the plane of motion and axis of movement is needed)
3. What would be the difference if you put a different ball (soft mini-basketball

Run the length of the basketball court. Answer the following questions

1. The basketball court is 26 meters long, how much work did you do?
2. How much force would you have generated if you simply ran into the wall at the end of the court?

Throw an object using a softball wind up vs circle motion of a shot put or discus throw.

1. What generates the most force? How?
2. How does inertia play a role in this experience?
3. How does torque play a role in this?
4. Use math/vectors to describe your answers. You do not need to be precise.
