Posture is the way our body is positioned when sitting or standing. Abnormal posture can develop at a young age or develop through daily repetitive work, or prolonged positioning.
We mostly rely on the dominant side of our bodies for daily functioning, which can sometimes develop acute overuse injuries. Over time, this can lead to chronic muscle overuse, inflammation and pain, and the pain then possibly lead to other functional limitations and adversely affect our ability to perform our daily activities at home and work.
Physical Therapists are trained in ergonomics (the study of people's efficiency in their working environment) as a means to help you prevent injuries in the workplace, either due to physical labor or even with prolonged sitting at your desk. Having the proper work station set-up is integral with prevention of overexertion from prolonged faulty posturing. A physical therapist can determine if your workplace setup is suited to you, and if not, make recommendations to modify things for your needs.
Poor posture can develop with certain neurological conditions/diseases, including post-stroke, Parkinson's disease, and Multiple Sclerosis. Physical Therapy can help in correcting the posture to improve your ability to walk and allow you to carry out your daily activities easier.
