6.   What range of motion (ROM) of the elbow and forearm (FA) is required to complete most activities of daily living (ADLs)? A.      Elbow extension/flexion 0/150; FA supination/pronation 85/80 B.       Elbow extension/flexion 90/150; FA supination/pronation 30/30 C.      Elbow extension/flexion 30/130; FA supination/pronation 50/50 D.      Elbow extension/flexion 0/90; FA supination/pronation 50/50 7.      Roz Evans’s Short Arc Motion (SAM) protocol is used for repaired extensor tendons in zones: A. IV-VII B. III-IV C. I-II D. V 8.   Your patient is 3 ½ weeks post zone 2 index finger flexor digitorum superficialis   repair.   He proudly demonstrates to you his full active fist despite being cautioned against making a full fist. You currently have the patient performing modified Duran exercises and place/hold in a ½ fist for hi...

6. Correct Answer:  C. Elbow extension/flexion 30/130; forearm supination/pronation 50/50  A biomechanical study of functional elbow motion has concluded that 30/130 of elbow ROM and 50/50 of forearm ROM are required to complete most activities of daily living (ADLs).  Answer A. lists typical ROM found in someone with an uninjured elbow or forearm.  ROM listed in answer B. may permit completion of some upperbody ADLs but is insufficient for completion of lower body ADLs due to limitation in elbow extension and forearm rotation.  ROM in answer D. may allow completion of lower body ADLs but not upper body ADLs due to lack of sufficient elbow flexion.      Reference :   Rehabilitation of the Hand and Upper Extremity, 6 th  edition.  Chapter 3; location 2478.  7.   Correct Answer:  B. Extensor zones III-IV The SAM protocol was developed t...

1.  Correct Answer: A.   Radial notch of the ulna and capetellum of the humerus  The radial head articulates with the radial notch of the ulna, secured by the annular ligament, creating the proximal radioulnar joint. It also attaches at the capetellum, which lies medial to the lateral epicondyle at the distal end of the humerus.  Reference: Rehabilitation of the Hand and Upper Extremity, 6 th edition. (Chapter 3) 2.   Correct Answer: A. FPB The flexor pollicis brevis muscle flexes the metacarpal phalangeal joint of the thumb and has a superficial as well as a deep head.  The superficial head is innervated by the median nerve while the deep head is often innervated by the ulnar nerve. The Abductor pollicis brevis and flexor pollicis longus are both innervated by the median nerve. The abductor pollicis longus is innervated by the radial nerve.
