<unk>  can stem from many sources; one of the most significant sources deals with repetitive motion without frequent breaks. If one spends a substantial part of one's day in a certain position without frequent reprieves, the spine tends to orient itself to that movement. For example, if someone is constantly leaning over to pick up objects, gradually the spine will start to develop a more exaggerated forward curve of the thoracic spine. Sullivan comments on<unk>  saying; "These problems<unk>  are often the result of chronic muscle tension, physical injuries or even emotional trauma, such as grief or depression. Conditions like these throw the musculoskeletal system out of alignment, and if not corrected,<unk>  eventually feels normal." Emotions, as well as physical activities, affect the state of one's<unk> . Other causes include sustained immobile<unk>  for long periods of time. Taylor, Consmüller, and Rohlmann in their article "A novel system for the dynamic assessment of back shape" in the Medical Engineering & Physics journal, say: "Low back pain is an increasing problem and can be aggravated by prolonged static<unk> . Sitting for prolonged periods is a great hindrance to good<unk> . According to a study conducted by a physical therapy firm in California, another cause of<unk>  can be linked to video games. While playing, it could only take a few minutes for a person’s<unk>  to be worsened. By focusing and leaning forward, the neck and shoulder 's alignment is compromised.<unk>  sitting<unk>  is hard to rectify. Jenny Pynt in The Physiotherapy Theory & Practice journal states, "In sitting there is no one ideal<unk> , nor should one<unk>  be sustained. Healthy sitting<unk>  therefore, is best thought of as an active not static phenomenon." Another cause for<unk>  is smartphone, usage of smartphone includes head movements, bends which causes pain around neck and shoulder muscles resulting in forward head<unk> . Warnings concerning backpacks and computer use Backpacks and computer use are associated with spinal distortions. The Sept/Oct edition of American Fitness in their article "Get in Straight: Simple Steps to Improve Your<unk> " quote Dr. Thielman who "cautions against carrying backpacks that weigh more than 20 pounds, attempting to lift object that are too heavy and repetitively making the same moves without taking frequent breaks. Any one of these activities encourages the forward leaning motion that causes<unk>  and back problems." Computer use and backpacks both favor the anterior leaning of the upper portion of the body. The weight of the backpack causes the shoulders to slump forward to compensate for the extra weight. The<unk>  used while carrying a backpack affects one's unloaded<unk> . In the article "Adolescent standing<unk> l response to backpack loads: a randomised controlled experimental study" in the 2002 edition of BMC Musculoskeletal Disorders 3 Grimmer et al. notes; "Unloaded<unk>  that habitually deviates from gravitational alignment has been associated with spinal pain." When one becomes accustomed to slumped shoulders when carrying a backpack, the action affects normal unloaded<unk> . Alternative backpack designs may help, such as non-flexible straps that prevent the backpack from shifting around. Computer use is also problematic concerning<unk> . An article in Consumer Reports on Health states, "The journal of electromyography and kinesiology found that<unk>  among computer users is an independent risk factor for musculoskeletal disorders of the neck and shoulders." Prolonged computer use with<unk>  can deform the thoracic and cervical spine. Steve Marshal in his article "Oh, My Aching Back!" in Occupational Health & Safety journal observes; "we do not as a whole, sit with proper<unk>  when using our computers.' 'We slouch, we hunch over and perhaps we sit cross-legged or curl our legs under our seats." This computer<unk>  may cause people to bend forward when not using the computer. There is growing evidence supporting the implementation of an alternative sit to stand workstation and ergonomical desk adjustments that yield positive effects reflected on computer workers and employers, studies by Thorp et al. for example found up to 32% reduction in pain and discomfort in lower back, and Pronk et al. showed a combined reduction of upper back and neck pain by up to 54% in office workers compared with pre-intervention data findings. According to a study by BMC Musculoskeletal Disorders, ergonomic chairs are a way for people to help treat and prevent their bad<unk> . Ergonomic chairs help with the alignment of shoulders, back, and neck. All things that are very important when it comes to<unk> .
Poor posture
Drunk walking
Risky sexual behavior
Physical disability
Frequent urination
Sedentary lifestyle
Pathological lying
