Question 40

What is the 2 formula for getting scapulothoracic rhythm

Answer 40

A) FORMULA #1

Step 1: Given SH ROM divide by 3 = N

Step 2:
N x 2 (for GH)
N x 1 (for Scapula)

B) FORMULA #2

Step 1: Given SH ROM - 30 deg = N

Step 2: N divide by 3 = Y

Step 3:
(Y x 2) + 30 deg (for GH)
Y x 1 (for Scapula)
