A Clinical Comparative Study of Ultrasound-Normal Versus Ultrasound-Abnormal XXXX .

@entity1 @entity135 @entity717 @entity9282
OBJECTIVE: To investigate the clinical features and outcome of outpatient-based physiotherapy (manual stretch) of @entity9282 ( @entity9282 ) with @entity135 limitation (>= 10  ) according to whether the finding on ultrasonography (US) is normal or abnormal. DESIGN: Case-control study. SETTING: Institutional practice. @entity1 : A total of 149 @entity1 with @entity9282 who met eligibility criteria were included: age at presentation  <=6 months, limitation of passive @entity717 (  ROT) or lateral flexion (  LAT) >= 10  , and completion of our outpatient-based physiotherapy program. INTERVENTIONS: @entity1 were allocated to the US-normal or US-abnormal group. @entity1 underwent physiotherapy and were followed-up monthly until   ROT and   LAT were  <=5   or did not respond to treatment. MAIN OUTCOME MEASUREMENTS: Baseline characteristics, initial   ROT and   LAT, age at presentation, treatment durations, and success rates of physiotherapy were compared between 2 groups. Treatment duration was adjusted for initial   ROT,   LAT, and age at presentation using analysis of covariance. RESULTS: Mean initial   ROT and   LAT in US-abnormal (28.5  ; 17.0  ) were greater than in US-normal (7.9  , P < .001; 12.3  , P = .001, respectively). Mean age at presentation was older in US-normal (3.8 months) than in US-abnormal (1.8 months, P < .001). Treatment duration was shorter in the US-normal (5.1 weeks) than US-abnormal (14.9 weeks, P < .001). Adjusted treatment duration was also shorter in US-normal (9.7 weeks) than US-abnormal (13.8 weeks, P < .05). The success rates of physiotherapy were 95% in US-abnormal and 100% in US-normal. Two of 6 treatment failures in the US-abnormal group underwent surgery. CONCLUSIONS: In @entity9282 with @entity135 limitation (>= 10  ), @entity1 in the US-normal group demonstrated lesser @entity135 limitation and older age at presentation than US-abnormal. It seems that US-normal showed shorter treatment duration irrespective of severity of neck motion limitation and age at presentation. Additionally, manual stretching applied before 6 months of age appears to show generally good outcome regardless of US findings.
