Hand MMT Flashcards
2 muscles responsible for wrist flexion and how to differentiate while testing
FCR = over 2nd MC
- flexion and rad dev
FCU = over 4-5th MC
- flexion and uln dev
Wrist flexion substitution
Finger flexors should stay relaxed
Muscles responsible for wrist extension and how to differentiate while testing
ECR - 2-3 MC
- ext and rad dev
ECU - 4-5 MC
- ext and uln dev
Wrist extension palpation
ECRL 2nd MC
ECRB 3rd MC
ECU 5th MC distal to ulnar styloid
Wrist extension substitution
Finger extensors should stay relaxed
Lunbricals/interossei testing position
Forearm supinated - resist MCP flexion and IP extension
Interossei and lumbricals are _______ muscles
Intrinsic
Substitution for lumbricals/interossei
Long finger flexors - IPs should remain extended
FDS testing position
Forearm supinated - hold all fingers extended except finger to be tested (eliminated FDP)
Pt flexes PIP
FDS palpation
Palmar surface of wrist between wrist flexors
FDS subs
FDP
Tenodesis action by extending wrist - results in passive flexion
Relaxing IP ext results in passive flexion
FDP testing position
Forearm supinated, stabilize middle phalanx - pt flexes DIP
Palpation for FDP
Palmar surface of middle phalanx
FDP substitutions
Tenodesis by extending wrist - results in passive flexion
Relaxing IP ext results in passive flexion
Finger extension position
Forearm pronated, pt extends MCP
Finger extension resistance
Applied toward flexion on proximal phalanx
