초록

This study is to evaluate the abnormalities in the kinetic chain in the players with little league elbow during themedical screening of middle school baseball teams. Ninety-three players were examined with elbow ultrasonographyin the field. Using kinetic chain evaluation test, 27 players sonogrphically diagnosed of little league elbow in dominantarm were compared with 25 players who were normal as control. Scapular-spine distance, horizontal flexion test,combined abduction test, and glenohumeral internal rotation deficit were used for evaluating kinetic chain in theupper extremities, while tightness of quadriceps and hamstring muscles, internal rotation of stance leg, and externalrotation of stride leg were used for lower extremities. Also, the single leg stance test and finger-floor distance wereused for core stability and flexibility. Twenty-five of 27 players (93%) having little league elbow showed kinetic chainabnormalities of either upper or lower extremities or trunk. This rate was significantly higher for the players havingthe little leaguer’s elbow than control (28%) (p=0.017). Each specific tests for evaluating kinetic chain were alsomore prevalent in little league elbow group than control, and the abnormalities in the upper extremity were morecommon than those in lower extremity (p=0.026). Combined abduction test (23/27) and limitation of internal rotationof stance leg (16/27) were the most prevalent abnormalities in upper and lower extremity test, respectively. Ourfindings showed that there are many abnormalities in kinetic chain in players having the little league elbow andit may be associated with pathogenesis of little league elbow.
