Strength Testing

Question 1

Describe the Oxford Scale (strength testing).

Answer 1

• 0 No muscle activation
• 1/I Trace muscle activation, such as a twitch, without achieving fullrange of motion
• 2/II Muscle activation with gravity eliminated, achieving full range of motion
• 3/III Muscle activation against gravity, full range of motion
• 4/IV Muscle activation against moderate resistance, full range of motion
• 5/V Muscle activation against examiner’s full resistance, full range of motion

Question 2

Describe how to complete resisted isometric muscle testing.

Answer 2

• use therapists resistance and compare to the other side as estimated %
• use dynamometer to get numerical value
• need to hold for 3-4 seconds (to ensure maximal contraction)
  (aim to do at mid-range, as can change depended on where/what length completed)

Question 3

What must you consider when completing a strength assessment?

Answer 3

• assess unaffected side first
• patient position
• patient instruction
• checking patient reaction
• STOP if painful
