Posture and Body Mechanics

With 80% of the population suffering from back pain at some point in their lives, it is important that we encourage proper posture and body mechanics through our practice. Faulty posture and body mechanics can lead to back pain which can worsen with unnecessary wear and tear. Explaining proper body mechanics to a client may improve their quality of life! Good body mechanics can prevent or correct problems with posture and protect your body from pain or injury.We can teach proper body mechanics such as bending at the knees rather then the hips when lifting objects from the floor. Another intervention would be to instruct the client on proper posture especially when sitting at a desk. It is easy to "slouch" while typing or writing at a desk. This puts a lot of stress on your cervical vertebrae. In pathology we learned about Wolff's law which states bone will adapt to the load under which it is placed. This explains why we may see a "hunchback" posture in some clie...

Neurobiology: The Influence of Advertisements on the Brain

Education Connection Commercial Jingle circa 2009 https://www.youtube.com/watch?v=WYS5NtRXlZQ   https://www.youtube.com/watch?v=WYS5NtRXlZQ I can confidently say that I know every word to the education connection jingle from their 2009 commercial. The advertisement targets young people considering higher education. Their service helps people “find the right college for free.”   I was 12 years old when the commercial first aired. I can distinctly remember singing the jingle at school with my friends. It was a bop! The jingle in the commercial is easy to remember, catchy and repetitive.

The part of the brain stimulated by music is the amygdala which is part of the limbic system. This area reacts emotionally to music by eliciting feelings of excitement, happiness, sadness, etc. The ventral tegmental area of the li...

Man from the South

In "Man from the South," we see a young and fearless solider being persuaded into a bet that could leave him little-fingerless. Even though the narrator and his new lady friend discourage him from playing into the bet he believes that he will beat the old man and win his Cadillac. The narrator built up the moment where the solider would either lose his finger or win and then the old man's wife barged in to stop him. She explained how her husband had collected many fingers and lost several cars with this same bet. The solider obviously did not recognize the power of his little finger. Assuming he lost the bet he would be losing about half of the strength of his left hand. Operating a firearm without a little finger would be hard for the solider. He could aim, pull and squeeze with his right hand but he needs the full strength of his left hand to support and stabilize the weapon. He might be able to use a prop to stabilize the weapon but this might not be the case for a...
