Rationale
1. Advancing the walker, then the left foot, followed by the right foot would place the involved limb at risk.
2. Protected weight-bearing gait involves advancing the assistive device, then the involved limb, then the uninvolved limb. This sequence allows the patient to safely decrease weight-bearing on the involved lower extremity.
3. From the starting point, advancing the walker first generates the new base of support needed for gait. Advancing the right foot, then the walker, followed by the left foot would place the involved limb at risk.
4. From the starting point, advancing the walker first generates the new base of support needed for gait.

Rationale
1. This answer is incorrect because there should be 20° to 30° of elbow flexion when an assistive device is fitted properly (Johansson, p. 377). Twenty to 30° of elbow flexion allows the upper extremities to provide support during all phases of gait and to absorb shock (O' Sullivan, p. 471).
2. This answer is incorrect because there should be 20° to 30° of elbow flexion when an assistive device is fitted properly (Johansson, p. 377). Twenty to 30° of elbow flexion allows the upper extremities to provide support during all phases of gait and to absorb shock (O' Sullivan, p. 471). At 15°, the elbow would not be at a mechanical advantage to lengthen as needed in gait.
3. The muscles of the arms should be positioned for biomechanical advantage to gain the most function from the energy expended; generally, this position is about 20° to 30° elbow flexion (Johansson, p. 377). Twenty to 30° of elbow flexion allows the upper extremities to provide support during all phases of gait and to absorb shock (O' Sullivan, p. 471).
4. This answer is incorrect because there should be 20° to 30° of elbow flexion when an assistive device is fitted properly (Johansson, p. 377). Twenty to 30° of elbow flexion allows the upper extremities to provide support during all phases of gait and to absorb shock (O' Sullivan, p. 471). Therefore, with greater elbow flexion, 45°, mechanical advantage is decreased.

Which assistive device provides the most support?

Walkers provide great stability due to their wide base, so they are great for people who can bear weight on their feet but have trouble walking due to weakness of the legs or balance issues.

Which device provides the most support and stability during ambulation?

Standard Walkers The standard walker is the most stable, but it requires a slower, controlled gait pattern because patients using it must be able to pick the walker completely off the ground and place it forward before stepping forward.

Which type of cane provides patients with the minimum amount of stability?

The number of points of contact with the floor determines the cane's stability level. Large-based (or broad-based) quad canes provide the greatest stability, whereas single-tip canes provide the least. Walking with a single-tip cane is more efficient, but less stable than using either a tripod or quad cane.

What assistive device is recommended for patients who need help with balance but not support?

A walker is an assistive device that helps patients ambulate. Some patients use walkers when they have poor balance. Walkers provide them with additional stability.
