The physician orders non-weight bearing with crutches for Joy, who had surgery for a fractured hip. The most important activity to facilitate walking with crutches before ambulation begun is:

  • Using the trapeze frequently for pull-ups to strengthen the biceps muscles

  • Sitting up at the edge of the bed to help strengthen back muscles

  • Doing isometric exercises on the unaffected leg

  • Exercising the triceps, finger flexors, and elbow extensors
