Importance in finding bony landmarks when measuring ROM:
  •  when measuring ROM you need a stabilized landmark to begin taking your measurement. 
  • bony landmarks are needed to align a goniometer
  • important to get the most accurate measurement you possibly can, so you can measure your clients progress throughout their therapeutic journey. 
  • needed to located bony segments that need to be stabilized when testing
  • used as reference points when measuring circumference

Test position for MMT:


 The purpose for the position when you're performing a MMT on a client is to get the most accurate readings. This determines effort by the patients and the strength of the patient  

 The BREAK Test is an example of a test, which is the most common test used, The Break Test is when the the muscle/ joint is placed in optimal position for contraction. This determining maximal effort, while the examiner gradually builds resistance. This is most common for evaluating individuals with physical disabilities. 


Gravity eliminated position

is when the joints are moving parallel to the ground causing resistance of gravity to be eliminated for the test movement. The force of gravity is perpendicular to the floor and the movement of the imp is parallel to the floor. 

 Example-  hip internal and external rotation while in the anatomical position. 
What is the relevance of the gravity eliminated position
1) The MMT will change depending on if the body is in a gravity eliminated position or not. 
2) When a patient muscles are too weak to move on their own. 
3) The effects of gravity are lessened in this position 
4) Less painful for the patient when measuring ROM for those experiencing pain.
5) Distinguishing of MMT grades.

Hierarchy of Mobility

By
The hierarchy of mobility begins with bed mobility. Improving a client’s overall bed mobility is extremely important to ensure that the client is not in one position for too long resulting in pressure wounds over their boney prominences. Next, is bed to mat transfers. Followed by wheelchair transfers, to bed transfers, to functional ambulation for ADL’s, to the toilet, to the tub, eventually working up to car transfers, and then beginning working on functional ambulation for community mobility, and then lastly driving. As you restore confidence in mobility and move up the client has more and more of a sense of independence.  Speaking firsthand, from someone who suffered a traumatic accident and has spent 2 months in a wheelchair secondary to a non-weight bearing orders. The hierachy gave me something to look forward to. Something minor like getting out of the bed and moving to a mat is not minor at all for someone who otherwise would have no choice. It gradually works to give ...

Man from the South

By
In the story, “Man from the South,” a soldier who was training to be in the U.S Navy was betting the destiny of his pinky finger based on a cigarette lighter.  If he loses the bet, and loses his pinky finger, he would most certainly have routine changes that would affect his occupations. Along with losing his pinky finger, he would also lose 50% of his grip strength. If he lost his dominant pinky hand then firing a firearm would be more difficult than if he lost on non-dominant hand however both affecting stabilizing the firearm thus creating poor accuracy. Soldiers have PT which usually involve pull-ups etc. this grip would be significantly affected. With the help of an occupational therapist to modify the handling of a firearm, a sling to help hold the gun in place and have better aim. If the wife would lose grip power for instance holding a vacuum handle, and other various household chores.

The Power of Posture

By
Proper posture and body mechanics are an essential role in prevention of energy and rehabilitation after an injury. Good posture allows our bodies to breath, move, and align properly causing minimal strain to the muscles and joints. Often times, we are unaware of our posture until the pain begins to interfere with our daily activities. Having proper posture and good body mechanics can: 1) Ensure efficiency in performing functional task 2) Prevent injury especially back injuries - most back problems result from poor posture and/ or bad body mechanics 3) Allow internal organs ability to function properly  4) Reduce stress that is put on the spine and avoid strains of additional muscles and ligaments  When teaching proper body mechanics and OT or an OT student would:    Ensure the client is educated on awareness of their own body mechanics. Modify daily task to insure minimal strain on the body. If a person works at a desk all day an example of a mo...
