A nurse is teaching a 75-year-old client how to properly use a walker. Which instruction should the nurse provide first?

Adjusting walker height so elbows are slightly bent ensures proper ergonomics and safety before teaching movement techniques. Other instructions are important but secondary to correct fit.

Understanding the Priority: Safety and Proper Fit

When teaching an older adult to use a walker, the very first instruction must center on safety and correct biomechanics, which begins with proper fit. A walker that is not adjusted to the correct height forces the user into a stooped or hyperextended posture, shifting their center of gravity and significantly increasing the risk of falls and musculoskeletal strain. Before any discussion of gait pattern, surface modifications, or environmental use, the device must be tailored to the individual’s body.

The instruction to check that the walker height is adjusted so your elbows are slightly bent when gripping the handles is the foundational step. This ensures that when the client stands upright inside the walker with shoulders relaxed and hands on the grips, the elbows are flexed approximately 15 to 30 degrees. This alignment is critical for two reasons: it provides optimal support during weight-bearing, and it allows for effective weight shifting and balance reactions. A qualitative study on walker design needs emphasized that conventional walkers frequently fail to accommodate end-user needs, with improper fit being a primary factor that can paradoxically contribute to fall risk rather than preventing it ^[1]. The research highlights that stakeholder perspectives consistently identify device customization as the essential first step in safe mobility aid provision, a principle that applies directly to the clinical teaching sequence.

Why Other Options Are Not the First Priority

The instruction to always move the walker forward first, then step into it with your weaker leg describes a correct gait sequence, but it is a secondary teaching point. A client cannot safely practice any gait pattern if the walker is at an incorrect height, as their posture will already be compromised. This sequencing is part of the physical rehabilitation approaches used to improve mobility, where the effectiveness of any technique is contingent upon the proper setup of the assistive device ^[2]. The systematic review on physical rehabilitation after stroke notes that the relative effectiveness of different approaches depends heavily on appropriate delivery and dose, which includes the correct application of the device itself ^[2]. Teaching the gait pattern before ensuring proper fit would be clinically unsound.

Placing tennis balls on the back legs of a walker is a common but informal modification intended to help the walker glide on certain surfaces. This is not an evidence-based first-line instruction and can actually create instability on other surfaces. It is a modification that would only be considered much later, if at all, and never before the fundamental step of height adjustment. Similarly, instructing the client to use the walker only on carpeted surfaces is incorrect and restrictive. Walkers are designed for use on a variety of stable, level surfaces, and limiting use to carpet alone would severely restrict the client’s functional mobility and independence. This instruction contradicts the goal of rehabilitation, which is to improve function and mobility across environments ^[2].

The correct clinical teaching sequence begins with a static, postural assessment to ensure the device is a safe match for the client’s body mechanics. Only after the walker height is verified and the client demonstrates proper upright posture with slightly bent elbows should the nurse proceed to dynamic instructions about gait pattern and safe ambulation on different surfaces.
