CHT Neuroanatomy/Nerve Injury & Sensory
Reeducation UPDATED ACTUAL Exam
Questions and CORRECT Answers
An order for hand therapy states "neuropraxic injury right median nerve". What information can
the therapist provide the patient regarding the injury and prognosis? - CORRECT
ANSWER - the prognosis is good and the patient should see recovery within one month
with treatment
A patient complains of parasthesia over the dorsal thumb 2 weeks after undergoing a thumb
CMC ligament reconstruction tendinous interpostion (LRTI) surgery. No other symptoms are
present. What is most likely causing this parasthesia? - CORRECT ANSWER - traction
injury to the superficial branch of the radial nerve when the nerve was retracted during surgery
True/False: proximal nerve injuries have a better prognosis for successful regeneration than
distal injuries - CORRECT ANSWER - false
A patient is evaluated for complaints of numbness in the thumb and IF 6 months after a carpal
tunnel decompression. The patient's job requires forearm rotation. The therapist is now
considering another nerve might be compressed causing the numbness. Of the choices below,
what would be the most likely compression site? - CORRECT ANSWER - Fascia between
the brachioradialis and ECRL
A 45 year old hand therapist complains of numbness in the SF/RF in both of her hands both
dorsally and volarly. On physical examination, her pinch and grip strength are normal as is her
cervical screening. She has a cutaneous pressure threshold for static two-point discrimination at
3mm. What is most appropriate treatment? - CORRECT ANSWER - night orthosis with
the elbow between 10 and 30 degrees of flexion
A 45 year old hand therapist reports numbness dorsally and volarly in the SF/RF in both of her
hands. On physical examination her pinch and grip strength are abnormal. She also has increased
cutaneous pressure threshold for static two-point discrimination at 8mm. What is the most
appropriate treatment? - CORRECT ANSWER - submuscular ulnar nerve transposition
, Which sensory receptor is responsible for detecting a sensation of a gentle breeze blowing
against the skin? - CORRECT ANSWER - pacinian corpuscle
30-hertz vibration is perceived by which of the following?
-slowly adapting Ruffini end organs
-quickly adapting Meissner corpuscles
-quickly adapting Pacinian corpuscles
-slowly adapting Merkel cells - CORRECT ANSWER - quickly adapting Meissner
corpuscles
Constant-touch pressure is perceived by what? - CORRECT ANSWER - large myelinated
A-b fibers slowly adapting
A 48 y/o man complains that his hands have become weak, and as an auto mechanic he has
burned and sometimes cut his fingertips without knowing it until he looked at his finger. On
physical examination, he has intrinsic muscle weakness and some wasting of the first dorsal
interosseous, with normal two point discrimination in his IF/SF. What is his most likely
diagnosis? - CORRECT ANSWER - syrinx
A 24 y/o man presents with inability to flex the tip of the thumb and IF. Physical examination
also identifies weakness in the deltoid. He has no history of injury; rather, the onset was sudden
and associated with pain in the shoulder and slight winging. He can recall working out in the
gym the week before symptoms occurred. What is his likely diagnosis? - CORRECT
ANSWER - parsonage-turner syndrome
A 19 y/o wrestler has pain in his anterior shoulder after having a shoulder arthroscopy approach
to repair his rotator cuff. His range of shoulder motion is limited by anterior shoulder pain. He
can localize the pain to the site of the arthroscopy portal anteriorly. What is his most likely
diagnosis? - CORRECT ANSWER - neuroma supraclavicular nerve
True/False: Reinnervation of a muscle is highly unlikely after 2 years of denervation -
CORRECT ANSWER - true
