National Physical Therapy Examination (NPTE) Practice Exam

A child with a unilateral hip disarticulation might find which activity to be the most difficult?

1. Rising from a wheelchair

2. Ascending stairs with a handrail

3. Descending stairs with a handrail

4. Ascending a curb

The correct answer is: Ascending a curb

A child with a unilateral hip disarticulation would likely find ascending a curb to be the most difficult activity due to the specific biomechanical challenges presented by this type of amputation. Ascending a curb requires not only an upward force to lift the body over the obstacle but also significant balance and stability. With a unilateral hip disarticulation, the absence of the hip and lower limb on one side means the child will need to compensate for the loss of strength and control on that side, which can lead to difficulties in maintaining balance and executing the movement effectively. The mechanics of stepping up onto a curb necessitate a coordinated effort, where the weight has to be shifted and balanced was accurately on the remaining limb while also creating enough force to elevate the body. In contrast, rising from a wheelchair, ascending or descending stairs with a handrail can involve using upper body strength to assist in the movement, often providing additional stability and support. These activities could be managed more easily through adaptations and the use of resources such as the handrail. While they still present challenges, they involve less requirement for unilateral propulsion and balance compared to the action of lifting and maneuvering over a curb.
