  Grip strength plays an important role across various activities and populations throughout the lifespan (2–9). As an older adult, it can even be used as an indicator of mortality.   An interesting study from 2010 looked to isolate different components of what make up the strength of ones grip (1). Specifically, the median and ulnar nerve contributions. This is an important impairment to consider when looking into rehab of various hand and elbow injuries. In the context of this video, we are considering the ulnar nerve contribution to grip. Injuries to the ulnar nerve tend to happen at either the cubital tunnel of the elbow or guyon’s canal of the wrist (10).   So, what did the 2010 study find? They found that when the 4th and 5th digit were not used during a hand dynamometer test, there was, on average, a 55% decrease in strength. Interestingly, it was the loss of the 5th finger which caused a greater reduction over the 4th; 33% and 21% respectively.  What does this mean for rehab? It is relevant to cue one to grip with their 4th and 5th digits when using various training apparatuses. This is straightforward in application and endurance based in prescription i.e. if the ulnar grip fails, then consider that the limiting factor, and stop that working set or activity.

  The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation).  Lungs are made up of areas called lobes – your right lung has three lobes, and your left lung has two. Your left lung is smaller than your right because it shares that side of the chest with your heart. The diaphragm, located below the lungs, is the primary muscle of respiration. When we breathe in, the diaphragm moves down to let air into the lungs. When we breathe out, the diaphragm relaxes and lets air out of the lungs.

  Magnetic resonance imaging (MRI) is a test that uses powerful magnets, radio waves, and a computer to make detailed pictures of the inside of your body. Your doctor can use this test to diagnose you or to see how well you've responded to treatment. Unlike X-rays and computed tomography (CT) scans, MRIs don’t use the damaging ionizing radiation of X-rays.
