Rotator Cuff Injuries

There are four muscles in the shoulder complex, which together make up the “rotator cuff”. They act together as dynamic stabilizers and movers in the shoulder. The four muscles involved are the supraspinatus, infraspinatus, teres minor, and supscapularis.

The supraspinatus, located on top of the shoulder, and the infraspinatus, which lies on top of the shoulder blade, are the two most likely to be injured. The main function of the supraspinatus is to lift the arm out to the side of the body, or abduct it. The infraspinatus externally rotates the arm, as if turning your palm facing forward.

 Exercising After a Stroke or Brain Injury

A stroke takes place when blood flow to the brain is blocked, resulting in a loss of brain function for 24 hours or more. Most strokes are a result of a thrombosis or embolism, with a small percentage stemming from a blood vessel hemorrhaging and leaking into the brain. Stroke is more common in men than women, and is the third greatest cause of death in North America. Common effects of stroke include aphasia (problems using and comprehending language), loss of sensory input ,a  very short attention span, poor short-term memory, and struggles with emotional control.

 Exercising with Angina and Silent Ischemia

The heart requires an uninterrupted, stable supply of oxygen to survive, since oxygen is virtually its only fuel. During our daily activities and exercise, the demand for myocardial oxygen varies. The heart  adjusts the coronary blood flow to meet the changing demand for oxygen. However when there is an obstruction in the coronary arteries, due to atherosclerosis, myocardial ischemia, or restriction in the blood flow, develops. When this condition causes pain in the chest, it is called angina.

Stable angina is usually associated with crossing the threshold of a certain level of physical exertion, or other stresses, such as emotional distress or cold temperatures. And is usually treated with rest and/or nitroglycerin.

Unstable angina is much riskier to deal with than the stable variety. There are three main hallmarks of UA:
