Is the Headrest just an accessory?

When prescribing a wheelchair and seating system, there is usually discussion on what are blanket-branded as accessories. When we look at the definition of an “accessory” we find:

NOUN – a thing which can be added to something else in order to make it more useful, versatile, or attractive. “a range of bathroom accessories”

synonyms: attachment · extra · addition · add-on · retrofit · adjunct · appendage · appurtenance · (additional) component · fitment · supplement

We could consider headrests and laterals as accessories by definition, but how well will the seating system work with asymmetrical postural needs without these components? Whilst a cup holder is an addition that is useful and potentially versatile, it’s not part of the seating outcome so much as an accessory that aids functional independence.

However, when we consider seating requirements it can create confusion when we use this wording “accessory” – especially when we are justifying equipment applications for a reader that may have little or no clinical experience. It is important to consider the language we use when articulating needs and using clear clinical justification for all the essential components of the solution.

Postural supports should not be seen as merely useful add-ons, but as a fundamental part of the overall solution. So, is a head support an accessory or a crucial part of the solution?


Headrests

When prescribing any seating component, we are essentially matching needs identified from the assessment to product parameters that provide points of control or forces that will support those needs. As such, identification of a headrest should be part of the initial postural solution, rather than viewed as an extra add-on at the end. What do we need to consider when identifying a potential head support?

A properly configured and positioned head support is an essential component of a wheelchair. The position of the head can affect common activities and daily functions such as:

  • Socialisation and communication
  • Safe swallowing
  • Respiration
  • Attention to task
  • Mobility

The first question to address is around the intended use. Is there a postural requirement to provide support, is it for resting when in tilted position, or is it to meet safety recommendations when using the chair as an occupant seat in transport? Each of these reasons will guide the potential solution.

Head Support for postural support

The head position will affect posture and balance, just as posture and balance affect head positioning. Poor seating positioning, unbalanced musculature, decreased innervation, and neural disruptions can all contribute to head position. Understanding where the head needs to be supported is crucial for best outcomes.

When considering a head support, a posterior head support is usually the simplest and least restrictive, as such this is likely to be an initial consideration. The pad is designed to be positioned in the suboccipital area with the goal to prevent excessive extension, rotation, or lateral flexion.

Other considerations include:

  • Address pelvis head and trunk alignment before trying to fit for a head support
  • Remember that head position changes constantly with the slightest body movement
  • Aim to position the pad in the suboccipital area posteriorly, and avoid resting on the ear if positioned laterally
  • Consider a head support with lateral, anterior/posterior, height, and angle adjustability, that can support the head posteriorly and laterally
  • Choose head support hardware that has offset capabilities to accommodate a head position out of midline

It is considered best practice to prescribe a headrest for mobility bases with tilt-in-space or recline features. It is important to consider the different impact that movement of the user’s centre of gravity will have on head positioning when utilising these chair features. Ensure it has been set to maximise support in positions required without impeding function in a neutral position.

The head support should not be seen as just an add-on: clinical consideration, function, and seating principles need to be applied to the clinical reasoning process. A head support shouldn’t be a prop for poor positioning, or a last minute add-on, but an integrated consideration.
