goniometry and muscle length testing

Question 1

What is joint ROM influenced by

Answer 1

bony structures and characteristics of CT surrounding a joint (ligaments and capsules)

Question 2

What is muscle length

Answer 2

the ability of a muscle crossing a joint to lengthen allowing 1 joint or a series of joint to move thru available ROM
(also described as flexibility

Question 3

Why do we need to quantify ROM

Answer 3

-objective or hypermobile, hypomobile or normal
establish a baseline to see improvement or lack of
develop plan of care and goals

Question 4

What are the landmarks for goniometer

Answer 4

axis
stationary arm
moving arm

Question 5

where is the starting position for goniometry

Answer 5

0-degree starting position of all joints except forearm which is fully supinated

Question 6

what is the procedure for measuring ROM

Answer 6

1. start as close to 0 as possibly
2. stabilize proximal joint segment
   slowly move distal joint to end of PROM, determine end feel, monitor discomfort and visually estimate ROM
3. landmarks….set up axis and align device using landmarks
4. compensations-realign as needed
5. record range of motion (start and end)

Question 7

Assessing muscle length

Answer 7

-greatest extensibility of muscle-tendon unit
-preparations/instructions similar to joint ROM

Question 8

guidelines for assessing muscle lenght

Answer 8

1. muscle placed in position to allow full ROM
2. place muscle lengthened across proximal joint
3. hold joint in rom while mov 2nd joint through full ROM
4. ensure proper alignment and use goniometer to measure if able
