Introduction

There is a known link between posture and vocal quality and posture and swallowing. When working with patients who have vocal problems or swallowing dysfunction, it is essential to be able to assess the impact of posture on these functions and vice versa.

This page will discuss the practical components of the postural assessment of a patient that may be useful for speech therapists. The theoretical aspects of the postural assessment are discussed here and here, and deglutition is discussed in detail here.

When assessing a patient’s posture, it is important to remain two or three metres from the patient in order to observe them fully. If you are using a postural grid app, it is important to be consistent in terms of the patient’s position each time you take pictures. For more information on using digital photography as an aid to postural assessment, please see the following articles:

• Two-dimensional digital photography for child body posture evaluation: standardized technique, reliable parameters and normative data for age 7-10 years
• Spinal postural alignment measurements using markerless digital photography

Evaluation in the Upright Position

The visual assessment of a patient should start in an upright, neutral position. In this position, it is important to verify the function of the vestibulospinal reflex. The vestibulospinal reflex works to maintain balance and posture by coordinating head movement with the action of the spinal muscles. The Rhomberg and Fukuda tests can be used to assess this function.

Rhomberg Test

The Rhomberg test is performed as follows:

• The patient stands with his / her feet together and arms crossed or held next to the body
• This position should be held for 30 seconds with eyes open, and then for 30 seconds with eyes closed
• The therapist observes the patient from the front and back
• In a normal test, there will be a slight, gentle oscillation
• In an abnormal test, the patient:
  • Is unable to maintain the test position without opening his / her eyes
  • Has to increase his / her base of support to maintain the position
  • Experiences large oscillations

If your patient has an abnormal Rhomberg, it is necessary to stop testing and refer on for medical review as it may indicate a neurological problem.

Fukuda Test

The Fukuda test evaluates the tension of the rotatory action of the postural chain and is performed as follows:

• The patient stands with arms extended in a circle with a radius of one metre

• This circle is divided into sections
• The patient is asked to step in place 50 times with his / her eyes closed and try not to move from his / her initial position
• The room should be quiet and dimly lit in order to reduce the chance that patients use light or sound to orient themselves
• The angle of rotation (i.e. deviation) and the distance of displacement (i.e. lateral shift) is measured
• A result is considered abnormal when a patient:
  • Deviates more than 45 degrees
  • Has more than a one metre lateral shift

Test Progressions

If the patient has a normal Rhomberg and Fukuda test, it is possible to further destabilise the system in order to evaluate the effect of the masticatory system and deglutition on postural control.

Deglutition

Repeat the Rhomberg test, but ask the patient to swallow while his / her eyes are closed. Look for:

• Lateral or posterior destabilisation
• Inclination (i.e. bending) or rotation of the head

Teeth in Contact

Remain in the Rhomberg position and ask the patient to close his / her mouth. Look for increased tension of the posterior chain.  

Decoaptation (i.e. opening) of TMJ

While in Rhomberg test position, place two balls of cotton wool between the teeth on each side and observe if this has any impact on postural control.

These progressions can then be assessed during the Fukuda test.

Posterior Analysis

The posterior observation provides information about:

• Tension in the shoulder elevators or altered scapula position
• Head inclination
• Asymmetry of the pelvis - e.g. lateral displacement
• Asymmetry in the lumbar paravertebral muscle mass
• A difference in the space between the arms and the trunk on each side
• Feet, ankle, knee alignment / position

Once you have completed a basic visual assessment, ask the patient to breathe in and out. Look specially for any elevation of the shoulder instead of lateral movement of the ribs.

Profile Analysis

From the side, the therapist should observe the patient’s alignment, looking specifically at:

• Head position
• Cervical spine alignment
• Thoracic spine alignment
• Lumbar spine alignment

Then consider if and how this position changes during swallowing, respiration and singing.

On inspiration, look for:

• Changes to the neutral position
• Retraction of the anterior part of the laryngeal chain

On swallowing, look for any large excursions:

• Slight flexion of the head during swallowing can be normal, but it can indicate retraction of the anterior laryngeal chain
• This type of retraction can be modified with re-education and with manual therapy

Frontal Analysis

Figure 1. Frontal analysis of posture.

When observing a patient from the front, it is important to check if the following points are horizontally aligned (see Figure 1):

• Bi-pupilar line
• Bi-condylar line
• Bi-mammillary line
• Bi-styloid line
• Bi-iliac line
• Bi-patellar line
• Bi-malleolar line

In order to further challenge the postural system while observing the patient in this position, ask the patient to open and close his / her mouth. Look for normal descent of the larynx and observe and palpate the anterior part of the hyoid.

Next check for movement during respiration and fast inspiration. Check if there is more movement in the upper chest, the lateral part of the chest or in the abdomen. Singers tend to use the inferior part of their abdomen more for inspiration than their upper chest.

During respiration, it is important to also observe the upper part of the neck and the head. Look for any flexion or extension (particularly during fast inspiration).

It is not possible to assess the diaphragm directly. However, it is possible to observe the muscles in the abdomen and use specific reference points in order to observe the effect of displacement of the visceral muscles during inspiration.

Analysis in Sitting

Specific postural patterns may be apparent in sitting including a forward head position. If a patient spends a lot of time in this position, his / her anterior chain may be retracted. You can observe sitting in profile or from the front.

Ask the patient to correct his / her posture, and see if he / she can maintain this position. Then assess inspiration in sitting. Check for:

• The amount of movement on inspiration - the abdomen moves less freely in sitting
• Extension of the head
• Forward position of the head
• Elevation of the shoulders
• Tension of the anterior neck

Then assess swallowing in the sitting position. During swallowing, look for:

• Neutral position of the head
• Correct movement of the larynx and hyoid
• Any compensations (rotation, flexion, bending of the head)

Finally, test glissato (glide from one pitch to another) and staccato (short, separate notes). During glissato, look for:

• Extension, flexion, or rotation during phonation
• Any tension of the perilaryngeal muscle masses (best observed from in front of the patient)

It is possible to ask the patient to increase the glissato range in order to evaluate perilaryngeal muscle effort and the impact of this range on the cervical spine - in individuals who have no dysfunction, the client will be able to maintain a neutral position at higher pitches.

During staccato, look at the movement of the larynx:

• The larynx should elevate and descend
• Check for any lateral movement or rotation of the larynx

It can be difficult to assess movement of the larynx, but it is possible to palpate movement with one finger. While palpating, also assess for any lateral tension or pain from the perilaryngeal muscles, the hyoid and hyoid muscles.

When asking patients to correct their posture, there are three potential outcomes:

1. The patient can actively correct the problem without the help of the therapist
   • For these patients, it is useful to prioritise active rehabilitation
2. The patient can correct his / her posture, but only with the help of the therapist
   • If there is pain, treatment priority is given to techniques that ease pain and to increase range of motion with passive manual therapy
   • Once pain is better managed, it is possible to move on to active rehabilitation
3. The patient cannot correct his / her posture or if he / she can move, this postural correction causes pain
   • In these cases, treatment priority is on pain management, often with medical treatments (medication, surgery)
   • Passive treatments may be beneficial to maintain range of motion / proprioceptive control

When there is pain, it is necessary to consider red flags:

• Disc degeneration
• Cancer
• Vascular conditions

Necessary Compensations

In some instances, compensation may be necessary to achieve respiration or swallowing. When there is a neurological problem, it is important to respect the condition of the patient and to maintain respiration / deglutition, even if there are postural compensations.

Whole Kinetic Chain

When correcting posture, consider the effect a change has both locally and globally. It is important to try to correct the whole kinetic chain.
