- repeat active movements & feel for crepitus

Question 24

Shoulder: special tests x 4

Answer 24

Supraspinatus ass: assessing function of supraspinatus
- ask Pt to abduct their shoulder from neutral position against resistance
- Loss of power suggest supraspinatus tear; pain in early abduction suggests tendonitis

Painful ARC - Impingement syndrome:
- passively abduct Pt’s arm to its max point
- ask Pt to lower arm slowly & back to neutral
- Impingement typically causes pain between 60-120* abduction

External rotation against resistance: tests motor funct* of infraspinatus & teres minor
- Positon Pt’s arms; elbows flexed @ 90* & shoulders flexed @ 30*
- ask Pt to externally rotate should whilst applying light resistance
- Pain on resistance; suggest tendonitis
- Loss of power; indicates tear

Internal rotation against resistance- Gerber lift off test: ass* funct* of subscapularis muscle
- ask Pt to place dorsum of hand on lower back

Question 35

Hand: special tests; Watson/Lumbrical/Flexor tend*

Answer 35

Watson’s test: AKA; scaphoid shift test - used to evaluate scaphoid stability: Ex places thumb over Pt’s scaphoid tuberosity (distal pole of the scaphoid, on the voler surface) & other fingers on dorsal surface of hand - Next; passive ulnar deviation (w slight palmar flexion) & then radial deviation (w slight palmar flexion) - pressure on tuberosity pushes scaphoid dorsally & out of the radial fossa = POS+ pain & clunk w movement Lumbrical plus finger: - tests laceration of flexor Digitorum Profundus distal to the Lumbricals: Pt attempts to make fist, finger unable to remain in gripped pose when Ex releases finger pressure (more common in 2nd Lumb* - middle finger) Flexor tendon integrity: Digitorum profundus; - Ex holds PIP of extended finger & ask Pt to flex DIP/ tip of finger Digitorum superficialis; - Ex keeps unaffected fingers extended & ask Pt to flex PIP of affect finger - multiple slips cut: identify tendons properly - Volar = middle and ring fingers - ALWAYS test thumb too; skier’s/greenkeepers thumb injury!

Question 36

Hand: special tests; Bunnell/Elson/Finger alignment

Answer 36

Bunnell test: - testing digit for intrinsic muscle or capsular tightness; Ex supports MCP w finger in extended pos* 1- w MCP joint extended, intrinsic contracture (Interosseous muscle contracture) impedes flexion of PIP 2- when MCP joint passively flexed, PIP joint flexion increases also Elson’s test: - test if Pt has central slip tear before the deformity is present (damage to tendons prox*/dist* to PIP joint 1- Pt has fingers over edge of table; PIP @ 90* 2- Ex places finger on middle phalynx 3- ask Pt to extend finger = Central slip intact - Ex feels tension of finger being extended = Ruptured central slip - No tension, Pt unable to extend PIP Finger alignment test: - slow, gentle creation of fist like pose watching how fingers align = Normal; fingers point toward scaphoid = Malrotation; affected finger will deviate from normal rotational direction *** esp* important w Finger # & Metacarpal #

Question 37
