Every morning, I start my day with a hot cup of coffee. I begin by sitting in my recliner with my coffee mug clasped in my hands about hip-level. In this position, my arm is adducted and my elbow is flexed about 90°. My wrist is slightly flexed as I grip the handle of the mug. After I bring the coffee mug to my lips, my elbow is almost fully flexed and my arm slightly abducted. Wrist remains slightly flexed throughout the movement. Elbow and wrist flexion occur in the sagittal plane about the frontal axis, while abduction of the humerus occurs in the frontal plane about the sagittal axis. The osteokinematic movement of the elbow is flexion in an open kinematic chain. In terms of arthrokinematics, the concave surface of the head of the radius rolls and glides anteriorly over the convex capitulum of the humerus to increase flexion. The prime mover for elbow flexion is the biceps brachii, which performs a concentric action.

The Road to Mobility

-
After an illness or injury, it important to take the proper steps of restoring mobility and function with a client. The sequence of mobility with increasing confidence and activity demands is bed mobility, mat transfer, wheelchair transfer, bed transfer, functional ambulation for ADL, toilet and tub transfer, car transfer, functional ambulation for community mobility, and community mobility and driving. Rather than quickly throwing him (or her) into "the ring,” a therapist starts small to help the client restore strength and confidence before providing them with greater challenges. In addition to promoting safety of the client, this method helps prevent further injury and disappointment.  Before starting OT school, I had not seen every step of this sequence because many of the clients I encountered were highly mobile. However, it makes sense to work from the most basic to the most complex skill in a sequential manner. We don’t try to teach our babies how to walk before they c...
