MSK peds Flashcards
questions to ask during hx
- age
- pain or weakness (night pain pattern/worsening often seen in neoplasm)
- trauma
PE
- gait
- inspection/palpation - abdomen, pelvis, back and extremities
- ROM
- neurovascular status - strength, sensation, reflexes
normal gait development
- walk w/o support by 12-15mos
- coordination with reciprocal arm swing by 2yrs
- req MSK development of lower back, pelvis, and LE
- neurologic growth - coordination/balance (myelinization in cephalocaudal pattern)
- adult gait pattern attained by 8-10yrs
normal gait phases
- stance - weight-bearing phase; heel strike -> plantar flex -> toe-off
- swing - toe-off -> heel strike; rotation and tilting of pelvis and stability of lumbar spine and abdomen
abnormal gait and cause
- antalgic
- trendelenburg limp - problem with glut medius of standing leg
- waddling - b/l hip involvement or neurologic disease
- stiff-legged
- toe walking - habitual or due to mm contractures, spasticity, or puncture wound to heal
- steppage - peroneal neuropathies
- stooped - abdominal pathology
- generalized mm weakness - muscular atrophy or metabolic cause
