Wheelchair Seating: Positioning the Head
1/12/2015 WHEELCHAIR SEATING: POSITIONING THE HEAD Introductions • Who I am • Who are you? • Goals for this session? • Handouts Michelle L. Lange, OTR/L, ABDA, ATP/SMS What we will be covering: Assessment • Positioning Assessment • To position the head, we first need to • Common positioning challenges of the head • Causes • The position of the head is extremely • Suggested strategies • Goals perform a seating assessment dependent on the position of the pelvis and trunk • Seat to back angle and position in space allows the client to “balance” the head Impact of general position on the head What do you think? • Kian • Kian • Very poor positioning led to extreme neck hyperextension • What is wrong with his head and choking position in this picture? 1 1/12/2015 What do you think? What do you think? • Kian • Kian • What would you adjust? • Hint: we already positioned the pelvis in neutral and adjusted the headrest • Supporting the trunk aligned the neck, reducing hyperextension and improving vision, breathing and swallow M. Lange 1.2015 Look Again… Positioning Challenges: Head • Decreased head control • No head control • Lateral neck flexion M. Lange 1.2015 M. Lange 1.2015 Let’s Try It! Let’s Try It! • “Normal” Head position • Flexed head position • Hold your head up as anatomically correct as possible • Note the position of your pelvis and trunk • Note your vision, swallow and breathing • Let your head fall forward • Note the position of your pelvis and trunk • Note your vision, swallow and breathing 2 1/12/2015 M. Lange 1.2015 M. Lange 1.2015 Let’s Try It! Let’s Try It! • Hyperextended head position • Lateral flexion head position • Let your head fall forward • Note the position of your pelvis and trunk • Note your vision, swallow and breathing • Let your head fall forward • Note the position of your pelvis and trunk • Note your vision, swallow and breathing M. Lange 1.2015 M. Lange 1.2015 Decreased Head Control Decreased or No Head Control • Possible Causes: • decreased neck strength • hyperextension of neck in compensation for poor trunk control • forward tonal pull • visual impairment, particularly a vertical midline shift M. Lange 1.2015 M. Lange 1.2015 Vertical Midline Shift Neck Hyperextension • Headrest not in optimal position • Trunk control not optimal • Where would you move headrest? 3 1/12/2015 M. Lange 1.2015 Correct Placement is critical… M. Lange 1.2015 Decreased or No Head Control • Interventions: • Increase trunk extension and scapular retraction • neck rest • posterior head support • change pull of gravity against head by reclining or tilting seating system • anterior solutions • refer to behavioral optometrist, if appropriate M. Lange 1.2015 Recline for Head Control M. Lange 1.2015 Posterior Head Supports • Many posterior head rests or head supports are on the market • None will be effective if the client’s head never touches it! • Tilt can be used to enlist gravity in the battle • Ensure that pelvis and trunk are in an optimal position to facilitate head control M. Lange 1.2015 M. Lange 1.2015 Occipital and Suboccipital Posterior Head Supports • Occipital support contacts the upper rear of the head • AEL • Suboccipital can actually provide postural support as it “cups” the occipital shelf • This also can reduce neck hyper extension occip ut Soft Curved Tri-pad Suboccipu tal shelf 4 1/12/2015 M. Lange 1.2015 M. Lange 1.2015 Posterior Head Supports Posterior Head Supports • Otto Bock • Otto Bock Concave, fixed or adjustable Lateral Control 3 pad, fixed or hinged M.

Lange 1.2015 Case Study Head Support Fitting • Hannah • Much improved visual gaze • Impact on swallow and breathing M. Lange 1.2015 Posterior Head Supports I2i Head Support • Stealth i2i • Clinical Indicators: • No pressure on the occiput for clients who extend in response to contact with this area • Encourages midline head position • Prevents hooking • Minimizes neck hyperextension • Head, Neck, Shoulders Positioning System 8 1/12/2015 M. Lange 1.2015 M. Lange 1.2015 Brian – seat to back angle i2i Head Support • Before and After M. Lange 1.2015 M. Lange 1.2015 Brian has limited hip flexion and so required a more open seat to back angle to prevent posterior pelvic tilt and improve head posture Brian Head Support Fitting: i2i Brian’s posture had worsened after an increase in dosage in his Baclofen pump led to very low tone in the trunk M.

Lange 1.2015 Custom Options • Sometimes a custom headrest is indicated for specific control Aspen Seating 10 1/12/2015 M. Lange 1.2015 Dynamic Options Dynamic Posterior Head Supports • Providing movement at the head has several goals: • Absorbs force to protect equipment from breakage • Diffuses force to reduce extensor patterns • Increases tolerance to seating system • Miller’s Adaptive Technologies M. Lange 1.2015 M. Lange 1.2015 Dynamic Posterior Head Supports Dynamic Posterior Head Supports • Miller’s Adaptive Technologies • Stealth Tone Deflector • 10 degrees any direction • Absorb and Avert! M. Lange 1.2015 Dynamic Posterior Head Supports Anterior Head Solutions • Symmetric Designs Axion Rotary Interface • Tread lightly – many clients will not tolerate anterior head support and many caregivers are resistant to the idea • Controversial whether to use in transport • At the least, use anterior trunk support if anterior head support is used • Soft collar is safest in transport • Do not attach collar to seating system 11 1/12/2015 M.

Lange 1.2015 Head Pod Decreased or No Head Control • Goals: • elongation of neck extensors (if shortened by neck hyperextension) • capital flexion (chin tuck) • to promote visual attention to the environment, peers, etc. • increased function • improved swallow, feeding, breathing M. Lange 1.2015 Decreased or No Head Control M. Lange 1.2015 Lateral Neck Flexion • Goals, cont.: • prevent subsequent deformity of neck and shoulder girdle • prevent over stretching of neck extensors and shortening of neck flexors (if head is usually hanging down) M. Lange 1.2015 M. Lange 1.2015 Lateral Neck Flexion Lateral Neck Flexion • Possible Causes: • decreased neck strength • muscle imbalance/tone/torticollis • ATNR • scoliosis • visual impairment, particularly a horizontal midline shift • Interventions: • address scoliosis • headrest with lateral support • posterior support with 3 point lateral control • either side of head and along jaw line that is deviated laterally • custom molded headrest • horizontal tilt, if severe and if pressure ok • refer to behavioral optometrist, if appropriate 14 1/12/2015 M.

Lange 1.2015 Case Study Case Study • Wesley • Age 8 • Diagnosis: spastic cerebral palsy • Manual tilt in space wheelchair • Linear seating system • Current access to AT: right head switch for AAC • Wes • Problem: his access has recently deteriorated, impacting his communication • Goal: to restore prior access skills 15 1/12/2015 M. Lange 1.2015 Case Study M. Lange 1.2015 Questions? • Wes • Evaluation: headrest had slipped back on hardware, requiring neck flexion against gravity and rotation for access • Solution: move headrest forward 1 ½” M. Lange 1.2015 Questions? M. Lange 1.2015 Product Demos • It can be challenging to recommend equipment without actually trying it out, particularly with certain items • Talk to Scott about product demos you may need, as well as your local Stealth rep M.
