The Use Of stretching to Prevent Loss of Joint Range Of Motion in Immobilized Muscle Flashcards
When a joint stays ______ in a shortened position there is both a ______ in muscle fiber length and a loss of ____ ______ and a _________ of the intramuscular connective tissue. This leads to ________ muscle stiffness.
immobilized
reduction serial sarcomeres
remodeling
increased
___________ Is a common complication of patients with muscloskeletal and neurological conditions
Limitation in ROM
What was the purpose of this study?
To determine weather or not there was a threshold duration which exists for any stretch induced effects
How did they achieve the purpose of the study?
What did they compare?
Have a CG - no stretching 1/4h stretching 1/2h stretching 1h stretching 2h stretching Effects of those aforesaid stretch durations and deg of ROM, SS# and Muscle weight
Why was muscle weight a test factor?
to see which of the durations would provide a decrease loss of muscle mass
Animals that had received 1/2h of stretching showed only __% loss in muscle weight compared with ___% loss in the contiously immoblized group CG)?
9% (1/2h)
48% (CG)
True or false. Stretching was also shown to prevent much of muscle loss which happens during plaster casting.
True
A regime which consisted only of 1/4h of stretching daily throughout the period of immobilization resulted in ____ ROM and a _____ though still significant ____ in Serial sarcomere number loss
improved
smaller
reduction
Periods lasting 1/2h of stretching daily throughout the period of immobilization were found to both _____ normal dorsiflexion and to _____ loss in ______ ______ #
maintain
prevent
serial sarcomere number
There was an ______ in serial sarcomere number as much as __% with 2h of stretching/ day
increase
10%
What amount of stretching caused an increase of as much as 10% in SS#
- 15 mins
b. 1/2 hour
c. 2h
c. 2hours
Did the results of the test support the theory put forward by herring et al?
yes.
According to harring et al. ______ ______ is regulated so that serial sacomere _____ is optimum for the muscle at which _______ levels of tension are exerted on the _____ rather than at _______
Serial sarcomere number length highest tendon resting length/ jnt position
The fact that adaption didn’t occur at the shortest time period may indicate that….
there is minimum period of time at which tension has to be maintained for adaptive processes to be started
Immobilzation of a muscle results _____ sarcomere leading to ____ in muscle fiber _____
loss
reduction
length
