Posture

Your current posture is the result of your body’s adaptations to the demands you place on it. Your body builds strength and flexibility where demaind is placed on it, and loses strength and flexibility when no stressors are applied.

The factors that lead to increased incidence of back pain are decreased muscle endurance and weakness rather than structural factors.

The key to resolving pain and discomfort is improving strength and endurance of the appropriate musculature.

Understanding Pain

One of the first models of pain was the gate ocntrol theory. This quickly became outdated, and 2 primary models remain: The neuromatrix theory of pain, and the biopsychosocial model.

The biopsychosocial model of pain asserts that there are biological, psychological and social factors that influence pain within the body.

biological factors
pain from repetitive stress, trauma, damage
psychological factors
effect of emotions and thoughts, mood, attention, sleep etc.
social factors
Social activities, work and occupation resulting in more isolation

The neuromatrix model looks at six areas, namely:

cognitive issues
memories of past experiences
sensory issues
nociceptive inputs from cutaneous, visceral and musculature senses
emotional issues
limbic system and stress mechanism
pain perception
sensory, affectieve and cognitive dimensions
actions
voluntary and involuntary actions
stress
immune system, cortisol, and other stress hormones

Pain is a protective mechanism, not necessarily a symptom of damage. Not avoiding various activities due to pain, and not changing your lifestyle around the pain are critical during a rehabilitation process.

The three most common causes of tightness in the back are pain, instability, or weakness. Your muscles may become tight to protect you from injury. Exercises that are aimed at strengthening and stabilizing the back tend to clear up such instances of back pain and tightness.

Posture in real life

Posture is a very complex interplay between the neurological and musculoskeletal systems within the body, which all come together to make up a specific position.

Aligning the joints into a better position would allow more muscular force to be used, yielding both improved performance, and less risk of injury.

We need to think about posture in the context of moving well, and the ability to adapt effectively to your environment while avoiding injury-prone positioning.

Correcting Posture

Consistent effort, over time, is one of the cornerstones of physical change, and everything you can do to encourage this is beneficial.

Upper Crossed Syndrome (UCS) and Lower Crossed Syndrome (LCS) describes patterns of weakness and tightness in the upper and lower body respectively, in the common desk job culture.

UCS: Head-forward posture: weak neck flexors, weak scapular retractors, tight upper cervical muscles/suboccipitals, tight chest pec/pec minor/rounded shoulders

LCS: Anterior pelvic tilt: weak glutes, weak abs, tight hip flexors, tight back

These are symptoms of the underlying cause. Any stretching and exercise is like a bandage. It will help cover a wound and protect it, but the real healing comes from your body engaging in the healing process. Mindfulness and sustained habits that aid this process are key.

Corrective Exercises

Mobility and stability exercises improve your range of motion through either dynamic movement or static holds. The strength and endurance movements contribute most to your ability to maintain good postural positioning in your daily activities.
