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.

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...

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...

Mobility Skills

-
The order for restoring confidence in mobility skills based on increasing activity demands is a concept that therapists can use to determine where to start with a client who has decreased mobility. The base of the hierarchy is bed mobility, then mat transfers, wheelchair transfers, ADL bed transfer, functional ambulation for ADL, toilet and tub transfer, car transfer, functional ambulation for community mobility, and lastly community mobility and driving. The order of the sequence allows for the completion of one skill to be followed by a more difficult skill. As OT's we want to promote independence. This hierarchy sets the client up to achieve several goals on the road to recovery.  I like this approach because it can be useful for any level of mobility skill. If a client's baseline is ADL bed transfer we assume that bed mobility, mat and wheelchair transfers (if needed) have already been accomplished. I did most of my observation hours in a pediatric outpatient clinic wher...
