Quiz #2: Elbow, Forearm & Pain Scales Flashcards
What is normal ROM for the forearm?
Supination 80*
Pronation 80*
What is normal ROM of the elbow?
0-150* Extension-Flexion
Convex/Concave Rule: Humeroulnar Joint?
Convex trochlea of humerus articulates with the concave trochlear notch of ulna.
Convex/Concave Rule: Humeroradial Joint?
Conveys capitulum of humerus articulates with concave radial head.
What are the average carrying angles for men and women?
Men- 10-12*
Women- 13-17*
What is the capsular pattern of the elbow?
ROM in flexion is MORE limited than extension.
Convex/Concave Rule: Superior Radioulnar Joint?
Convex radial head pivots in the concave radial notch of the proximal ulna. Stabilized by annular ligament.
Convex/Concave Rule: Inferior Radioulnar Joint?
Convex ulnar head pivots in convex ulnar notch of distal radius.
What is the capsular pattern of the forearm?
Equal limitation of pronation and supination.
What muscles are being tested during Elbow Flexion? What nerves?
Biceps- musculotaneous
Brachialis- musculotaneous
Brachioradialis- radial
What muscles are being tested during Elbow Extension? What nerves?
Triceps- radial
What muscles are being tested during Forearm Supination? What nerves?
Supinator- deep radial nerve
What muscles are being tested during Forearm Pronation? What nerves?
Pronator Teres- median
What substitutions can occur during pronation?
Patient may IR shoulder or ABD shoulder
What substitutions can occur during supination?
Patient may ER and ADD arm across body
Patient should be instructed to keep wrist and fingers relaxed to avoid substitution by wrist extensors.
What substitutions can occur during external rotation?
Patient sitting with arm ABD, may ER the shoulder and gravity extends the elbow.
What substitutions can occur during horizontal adduction?
Distal segment fixed, patient horizontally adducts the arm and thrusts the elbow into extension. Used by patients with cervical SCI.
Special test positive finding: pain along lateral epicondyle or objective ms weakness with discomfort may indicate lateral epicondylitis?
Resistive tennis elbow test (cozen’s test)
Special test positive finding: report of oain along lateral epicondyle may indicate lateral epicondylitis?
Passive tennis elbow test
Special test positive finding: report of pain along the medial aspect of the elbow indicates medial epicondylitis?
Golfer’s elbow test
Special test positive findings: damage to radial collateral ligament?
Varus stress test
Special test positive findings: indicates ulnar nerve compromise?
Tinel’s sign
Special test positive findings: indicates pathology of the anterior interosseous nerve?
Pinch grip test
What 4 joints does the Biceps brachii cross?
Glenohumeral
Humeroulnar
Humeroradial
Superior Radioulnar
What 2 joints does the Triceps Brachii cross?
Glenohumeral
Humeroulnar
Pain Scales: Numeric Pain Scale
Verbal rating scale
0-10 point scale is used
Obtain a subjective rating of pain intensity from the patient. Used for quick measurement.
Pain Scales: Visual Analog Scale
Provides quantitative measures of a patients pain intensity.
Instrument consists of a 10cm line with descriptions at each end.
Pain Scales: McGill pain Questionaire
Provides quantitative measures of clinical pain that can be treated statistically.
20 categories of words used to describe pain or the patients pain experience.
Pain Scales: Pain Drawing
Is an aid to document the spatial distribution of a patients pain symptoms.
Different symbols represent different types of pain.
Pain Scales: Wong-Baker Faces Pain Rating Scale
6 faces are used that are numbered 0-5 underneath.
Used for kids to show pain level.
Pain Scales: Dallas Pain Questionnaire
Designed to assess the impact of chronic pain on a patients life.
16 item visual analog tool
Pain Scales: Oswestry Low Back Pain Disinility Questionnaire
This questionnaire measure a patients perceived disability as it relates to low back pain.
