National Physical Therapy Examination (NPTE) Practice Exam

For a K2 level ambulator with a unilateral transfemoral prosthesis navigating steep inclines, which technique is most appropriate?

1. Lead with the prosthetic limb and ambulate with a reciprocal gait pattern

2. Lead with the contralateral limb and ambulate with a reciprocal gait pattern

3. Lead with the prosthetic limb and ambulate with a step-to gait pattern

4. Lead with the contralateral limb and ambulate with a step-to gait pattern

The correct answer is: Lead with the contralateral limb and ambulate with a step-to gait pattern

For a K2 level ambulator navigating steep inclines, leading with the contralateral limb while using a step-to gait pattern is appropriate due to several factors that align with the functional capabilities of a K2 level ambulator. Individuals classified as K2 demonstrate the ability to traverse uneven surfaces and negotiate curbs but may not have the strength, stability, or coordination required for more advanced gait mechanics. Leading with the contralateral limb helps ensure stability and provides a solid base of support as the individual ascends or descends an incline. This technique also enables more effective weight shifting and propulsion from the sound limb, which is critical when managing steep surfaces. Using a step-to gait pattern allows the user to maintain closer proximity to the incline and can simplify the movement, aiding in balance during the transition of weight from one limb to the other. Overall, this approach maximizes safety and efficiency, supporting the user's functional mobility while taking into consideration the potential weight-bearing limitations and balance challenges associated with a unilateral transfemoral prosthesis.
