The Clinical Research And Practice Podcast

Neck pain and posture are frequently linked in many conversations regarding origin or recurrence of neck pain, in desk ergonomics and workplace health education. 

This episode looks into the literature examining the relationship between neck pain and postures involving the head, neck, and shoulder girdle. 

-       Does posture relate to neck pain

-       Is there such a thing as text neck

-       Does correcting posture reduce neck pain?

-       If not posture, then what factors predict neck pain?

Let's see if we can answer these questions...

Posture is a widely discussed and debated topic. The workplace, health ad safety, and medical industries have all played a role in the current societal beliefs about posture. This episode aims to identify the origins of the current posture beliefs and explore whether the research supports these beliefs.

The sacroiliac joint (and pelvis as a whole) is a popular area of focus for Osteopaths in training and in practice. We are taught to palpate, examine, and diagnose 'sacroiliac joint dysfunctions' and 'sacral torsions', but is there any evidence that these assessment methods are reliable or valid? 
 We'll discuss the assessments used, the reasoning behind them and their place in clinical practice, and we'll pick apart some research investigating these concepts.
 Come with me as I walk through some of the research findings related to this question. 

Whether you use joint manipulation/adjustments/HVLA techniques or have had them done, you have probably asked "what actually makes the popping or cracking sound?"
 
 In this episode I delve into the research we currently have available and see if we can come up with an answer to that question

It's a topic that comes up a lot in clinical practice......should you use ice/cold or heat? Whether you are an elite athlete, weekend sports-person, or you suffer from occasional aches and pains, this information may be useful to you in deciding which is best to apply.
 In this episode I summarise what the research says about the effects of heat or cold, as well as how and when to use each.
