Positional therapy for POSA (Positional Obstructive Sleep Apnoea) is a non-invasive treatment that reduces obstructive sleep apnoea events by encouraging side-sleeping instead of back-sleeping.
This service is for people who have a confirmed diagnosis of obstructive sleep apnoea and whose sleep study shows breathing events are significantly worse when lying on their back. It can be used on its own in carefully selected cases, or alongside other sleep apnoea treatments.
Positional obstructive sleep apnea (POSA) is a form of obstructive sleep apnoea where breathing disturbances vary depending on sleep position.
When lying on the back (supine), gravity can cause the tongue and soft tissues of the throat to fall backwards. This narrows the airway and increases the likelihood of collapse during sleep. When lying on the side, the airway may remain more stable, reducing breathing interruptions.
On a sleep study, this may show up as:
For some people in the Albury–Wodonga region undergoing sleep testing, this positional pattern is clinically significant and helps guide treatment decisions.
Positional therapy is generally considered for people who already have a confirmed diagnosis of obstructive sleep apnoea and have undergone a comprehensive sleep assessment.
In practice, this service may be suitable if:
It’s also important to understand when positional therapy may not be appropriate. If sleep apnoea remains moderate or severe in all sleep positions, positional therapy alone is usually not sufficient. Individual clinical assessment is essential before starting treatment.
The goal of positional therapy for POSA is simple: reduce the amount of time spent sleeping on the back.
Modern positional therapy uses behavioural conditioning rather than physical restriction. A small device monitors sleep position overnight. When sustained back-sleeping is detected, it delivers a gentle vibration prompt to encourage a shift to side-sleeping. Most people adjust without fully waking.
Over time, this can help reinforce side-sleeping patterns and reduce airway collapse during sleep.
As with all obstructive sleep apnoea treatments, consistency matters. Therapy effectiveness is reviewed to ensure breathing events and symptoms improve.
Positional therapy at Border Sleep Centre is delivered as part of a personalised, evidence-based sleep apnoea care pathway for patients across Albury, Wodonga, and surrounding communities.
Care begins with a detailed review of your sleep study to confirm whether positional obstructive sleep apnoea is present. We then:
If positional therapy alone does not adequately control your obstructive sleep apnoea, we discuss alternative or combination treatment options. Care is collaborative and individualised at every step.
Like all sleep treatments, positional therapy for POSA has both advantages and limitations.
Regular clinical review helps ensure treatment remains effective and appropriate over time.
If your sleep study shows positional obstructive sleep apnoea, the next step is a clinical review at Border Sleep Centre.
This appointment allows us to explain your results, confirm whether positional therapy is appropriate, and discuss how it may fit within your overall treatment plan. Ongoing monitoring helps ensure your breathing and sleep quality remain well controlled.
It means your breathing events occur more frequently when sleeping on your back compared to your side.
For some people with positional obstructive sleep apnoea, it may be an alternative. For others, it may be used alongside CPAP or other treatments, depending on severity and response.
Most people are unaware of their sleep position. Your sleep study data, combined with clinical assessment, helps determine this.
It can be. Ongoing review ensures breathing events and symptoms remain well controlled and that the therapy continues to suit your needs.
