Strenght Testing (movers)

Question 1

Why do we do muscle strength test

Answer 1

Insight into the contributing factors of poor movement/performance

Test ability of muscle to contract

Question 2

Three things you want to know when testing for muscle strength

Answer 2

1. Activity? (Weak muscle)
2. How open its contract plus perform function
3. Maximum tension generated? (Maximum strength)

Question 3

Advantages of testing using hands (manual muscle test)

Answer 3

Quick/reliable

Question 4

Most common method for muscle testing(hand)

Answer 4

Oxford scale

Question 5

Purpose of Oxford scale (2)

Answer 5

Grades concentric muscle strength
Determine ability (strength)of muscle to move body segments through FROM against gravity

Question 6

Plus and minus the determination

Answer 6

-: Higher than 50%
Lower than 100%
Short of FROM

+ : Higher than 0%
Lower than 50%
Capable of little more than grade testing

Question 7

What is dynamoMetry

Answer 7

It is a quantitive talk about assess muscle strength

Gold standard is Isokinetic

Question 8

Name three types of dynamometry

Answer 8

Handheld
Hand
Isokinetic

Question 9

Three facts about handheld

Answer 9

Efficient/objective/sensitive/affordable
Use during maximum isometric contraction
Tests prox and distal muscle

Question 10

Three facts about hand

Answer 10

*Patient will exert maximum force
*Examiner: counterforce (make test)
Break contract (Break test)
*Disadvantages: limited to isometric testing

Question 11

4 facts about isokinetic dynamometry

Answer 11

Disadvantages: cumbersome/expensive

#. Measures: strength - muscle length -velocity relationship
# measures all types of muscle even eccentric muscle
#Useful: diagnose muscle imbalance Ie. Agonist and antagonist during movement

Question 12

Oxford scale number meaning

Answer 12

0: nothing
1: muscle contract no mvt
2: mvt but gravity eliminated
3: against gravity only
4: mvt against some R
5: mvt against full R
