Lab 1: Muscle Imbalance: UCS and LCS

Question 1

When testing LE extension muscle balance what should the perceived firing pattern be?

Answer 1

• Ipsilateral hamstring
• Ipsilateral gluteus maximus
• Contralateral e. spinae
• Ipsilateral e. spinae

Question 2

When testing LE abduction muscle balance what should the perceived firing pattern be?

Answer 2

• Ipsilateral gluteus medius
• Ipsilateral TFL
• Ipsilateral QL
• Ipsilateral e. spinae

Question 3

Which muscles are facilitated and which are inhibited with a positive cervical flexion test?

Answer 3

• Facilitated = SCM and scalenes
• Inhibited = deep neck flexors (longus colli)

Question 4

A positive scapular stabilization test indicates weakness of which 3 muscle groups?

Answer 4

• Lower trapezius
• Serratus anterior
• Rhomboids

Question 5

How to perform Pectoralis Minor Asymmetry and Passive Range of Motion Testing for Muscle Imbalance?

Answer 5

• Pt lies supine and doc stabilizes shoulder of side not being tested
• Doc applies a posteriorly directed force against the shoulder being testing and notes PROM and end-feel; repeat on other side
• (+) test = diminished PROM of one side compared to the other and/or hard end-feel

Question 6

Where is the TP for the Scalenes and what is correct position for tx?

Answer 6

• Inferior to the clavicle 1/3rd the distance from midline along the clavicle on the 1st rib and 2/3s the distance from the midline along the clavicle on the 2nd rib
• F ST RT

Question 7

How to perform CS to Levator Scapula?

Answer 7

Monitor TP and with other hand on pt’s ipsilateral wrist the doc extends the arm and places it under traction or compression depending on which give greatest relief

Question 8

How to perform the Levator Scalulae Still-ish technique?

Answer 8

• Pt sitting w/ doc standing behind pt. Start by ABducting the pt’s arm to 180°
• Provide distraction, ADduction to 90° and finally to 0°
• Have pt grab the back of table, while doc flexes head toward opposite knee
• 3 deep breaths and follow fascial release

Question 9

Proper position for SCM CS?

Answer 9

F ST RA

Question 10

What is the correct positioning for CS of AC1-AC8?

Answer 10

• AC1 = RA
• AC2-6 = F SA RA
• AC7 = F ST RA
• AC8 = F SA RA

Question 11

How to correctly perform pectorals CS?

Answer 11

Adduct arm across midline
