Measuring and Sizing Hensinger Head Support

Instructions for Sizing

It is important to work with a health professional when sizing head supports. The soft foam collars are made to allow the individual using the support to benefit from being able to easily move his or her head to retain function, instead of being held in a tight, restrictive position. The individual seating system must always be addressed first to provide stability to the pelvis and trunk.


  1. Take the neck circumference and round to the nearest 1cm.

  2. Measure vertically between the top of the shoulder and the bottom of the ear lobe and round off the nearest 1cm. Then subtract 1.2 cm to allow for ear clearance and head movement.


If a chest support is used and it fits over the shoulders, subtract its thickness from the B measurement (thickness less than 3mm should not affect the fit)

Alterations in size can be achieved using size reducers/increasers depending on needs. Please contact us for more information.

Head Support Consideration

Proper selection of a head support requires that a professional evaluation take place, including the following factors:

  1. Breathing should be improved or maintained at the present level

  2. Swallowing/drainage should be improved or maintained at the present level

  3. Head contact areas: head supports maintain the head in mid-line position. The portion of the neck/head area that contact the support is considered the ‘base area”. Determining the base area help provide support and maximum comfort. Improper base area selection cam impede breathing, swallowing, blood flow, and possibly jaw discomfort.

  4. Body positioning: head support must only be used in conjunction with correct trunk support.

  5. Head control: the level of head control and support needed should be determined professionally.
