The left diaphragm tends to be more flattened (stuck in a state of inhalation) and the left abdominals tend to need more integration into functional movement patterns. The design of our organ system is asymmetrical – the right hemi diaphragm is supported by the liver. “Ladies Love Cool J” stuck in right stance PRI practitioners assess and treat an individual’s ability to achieve left stance phase of gait. This means that the left abdominals, hamstrings, adductors, and glutes need to be trained to restore alternating and reciprocal function. The Postural Restoration Institute discusses this in detail but in short, the compensatory right dominant strategy that many individuals utilize produces ribcage flair on the left. However, if you look closer what you will find is that the right side will always be more limited (even with left handed people).This is driven by the right hemi diaphragm orienting the spine and pelvis to the right. Some individuals will have limited internal rotation on both sides. But rather than jumping in and just stretching the shoulder let’s restore respiration, fully exhaling and resetting the ribcage. If your nervous system cannot alternate between a relaxed and ready state then your structural alignment will be affected. This means that blue light, loud noises, aggressive stretching, and over reliance on bilateral movements all have the potential to lock up your shoulder. Ribcage flair is supported by a sympathetic nervous system state (fight or flight). #2: Respiration Influences Neurology Which Influences Muscle Tonus If you want to restore range of motion you need to provide an individual with a different respiratory strategy so that their shoulder blades can rest properly on a neutral ribcage. Diaphragm function will influence the position of the ribcage and the tonus of the deep hip flexors which influence the pelvis and ribcage. The diaphragm has both respiratory and postural roles. Then re-evaluate the shoulder.ĭo not ignore the need for abdominal activation to reposition the ribcage into a neutral position. In this scenario use a positional breathing drill to restore the neutrality of the torso. Before stretching the shoulder ask yourself if a flared ribcage is limiting shoulder rotation. When looking at shoulder internal rotation it is important to first evaluate the position of the ribcage. The hamstrings, for example, are a common muscle group that are blamed for a variety of range of motion limitations including the straight leg raise, the forward bend, and the ‘butt wink’ at the bottom of the squat.īut when we look closer and understand what is truly causing these limitations – anterior pelvic tilt limiting the straight leg raise and limited hip flexion causing the butt wink – we begin to appreciate the importance of proper assessment which prevents overstretching of muscles, tendons, and ligaments. Certain muscle groups are then blamed and inappropriate stretches are performed. Oftentimes range of motion limitations are misdiagnosed. The sleeper stretch is a popular shoulder exercise but there are some factors you should consider before deciding on its appropriateness.
