Scapulohumeral Rhythm

-
The scapulohumeral rhythm allows full ROM and muscle length tension through the motion of shoulder elevation. Shoulder elevation is a synchronous movement between the glenohumeral joint and then scapulothoracic joint.  This means that as the angle of the glenohumeral joint increases during abduction, the scapulothoracic joint moves as well in upward rotation. The scapulohumeral rhythm consists of a 2:1 ratio of glenohuneral joint movement to scapulothoracic movement that produces 180° of full ROM. When we have a client perform abduction/elevation of the upper extremity we observe the rhythm to ensure the total motion. We can observe weakness in the muscles that produce scapular upward rotation such as the trapezius or serratus anterior during the motion. If the scapula does not upwardly rotate, abduction of the humerus will not be complete.  Moreover, dysfunction in one of the joints can decrease ROM or cause impingement/pain.  This may be evident if th...

Imposter Phenomenon

-
 Imposter phenomenon/syndrome is something that can affect any new employees. It can make you feel unprepared, inadequate, and out of place in a new and competitive environment. The article, "Facing Imposter Syndrome as a New Grad," is very helpful in guiding new grads to assess and confront the characteristics of someone struggling with this issue. I scored less than 30 on the Clance IP Scale meaning I show very few characteristics of Imposter Syndrome. I feel that the questions asked in this assessment were very indicative of the external locus of control that I discussed in my previous blog. I personally relate to a more internal locus of control in that I don't believe I am lucky or successful by chance. I believe that hard work, dedication and passion promote success.  Overall these materials were helpful in identifying negative thought patterns and feelings associated with imposter syndrome. With this knowledge I will be more prepared to confront imposter syndrome h...

Test Positioning

-
The bony landmarks we refer to when measuring ROM (range of motion) guide where we palpate and place the goniometer. It is important for each arm of the goniometer to be accurate to ensure accurate readings. The proper positioning of the client ensures that the readings are accurate when determining full ROM. Proper positioning also promotes safety of the client which is our main priority. In manual muscle testing we want to start where the greatest mechanical advantage and optimal muscle contraction will occur. This is the “test position” and is typically mid ROM. In MMT we always test against gravity before we eliminate gravity. The relevance of the gravity eliminated (GE) position is that it allows us to perform the MMT safely for clients with poor muscle strength. The gravity eliminated position is parallel to the ground which alleviates resistance. This removes a barrier for people who can not complete full ROM against gravity.
