Q

WB motion: limited
NWB motion: WNL
likely cause/general Rx?

A

joint hypermobility with impaired neuromuscular control
improve neuromuscular control

17
Q

RST
strong and painful indicates

A

less severe injury
grade 1 strain
typically only painful in lengthened position

18
Q

RST
weak and painful indicates

A

acute
moderate-severe injury
grade 2-3 strain/fx

19
Q

RST
weak and painless indicates

A

neuro damage
chronic contractile rupture

20
Q

RST
pain upon release indicates what tissue

A

non contractile tissue
glide is released when muscle relaxes

21
Q

RST
multiple joints of weakness indicates what tissues

A

CNS/UMN innjury
entire UE

22
Q

RST
multiple planes of weakness indicates

A

acute/severe injury
fracture

23
Q

RST
weakness throughout a range and not just mid range indicates what kind of injury

A

possible pathology

24
Q

RST
improved pain and/or function indicates

A

inhibited muscle
regional interdependence
disc injuries

25
Q

RST
decreased force indicates

A

nerve palsy

26
Q

RST
consistent weak force indicates

A

deconditioned/torn muscle

27
Q

RST
worse pain/function indicates

A

acute condition

28
Q

ST
pain increases with distx indicates

A

capsule, ligament, annulus

29
Q

ST
pain decreases with distx indicates

A

bone, cartilage, nucleus pulposus

30
Q

ST
pain increases with compression indicates

A

bone, cartilage, nucleus pulposus, spinal nerve

31
Q

describe LMN common findings

A

muscle tone: decreased/flaccid
bowel/bladder: incontinence/leakage
dermatomes/paresthesias: single segment diminished
DTRs: hypoactive
myotomes with potential sexual dysfunction: single segment of fatiguing weakness

32
Q

describe UMN common findings

A

muscle tone: increased/spastic, UE flx causes LE flx, co-contractions
bowel and bladder: spastic/retentive
dermatomes/paresthesias: multi-segments diminished
DTR: hyperactive
myotomes with potential sexual dysfunction: multi-segment weakness, incoordination, paralysis

33
Q

why would you perform accessory motion testing

A

if limited ROM and/or consistent block during combined motions

34
Q

if accessory motion is limited and ROM is limited, where is the restriction most commonly located

A

articular
related to joint restriction
ex) capsular shortening or cartilage restriction

35
Q

if accessory motion is WNL and ROM is limited, where is the restriction most commonly located

A

extraarticular
ex) muscular shortening, guarding, joint hypermobility

36
Q

what is the purpose of a special test

A

identify tissues by the reproduction of symptoms during test

37
Q

what is the purpose of stability tests

when do you perform stability tests

A

assess integrity of non-contractile tissues

perform if excessive ROM and/or consistent block noted with combined motions
