Kin 1 Muscle Length Assessments

Notes

Focus on muscle action and how the muscle contracts

● Origin and insertion will move away from each other (distracted)

● The length test = OPPOSITE ACTIONS OF THE TARGET MUSCLE LIKE YOU’RE STRETCHING THE MUSCLE

● Passive tests

● Maintain the end position of the first join manipulated and then move onto the next joint

Stiff vs. Short

• If muscle MOVES and SHIFTS = stiff

• If muscle is STUCK/NO CHANGE = short

• Compare bilaterally

• “Best for last”

  • when testing proximal v. distal ends, the last portion you move is going to be what you are testing
