STUDY DESIGN A retrospective study of standing imbalance and body posture in 71 able-bodied girls and subjects with adolescent idiopathic scoliosis was conducted. OBJECTIVE To test the hypothesis that postural parameters are related to standing stability parameters. SUMMARY OF BACKGROUND DATA Spinal deformity not only modifies the shape of the trunk,(More)
In considering the influences of microsystems on adolescent substance use, familial and peer contexts have received the most extensive attention in the research literature. School and neighborhood settings, however, are other developmental contexts that may exert specific influences on adolescent substance use. In many instances, school settings are(More)
In the thymus, 2 types of Lin-Sca-1+ (lineage-negative stem cell antigen-1-positive) progenitors can generate T-lineage cells: c-Kit(hi) interleukin-7 receptor alpha-negative (c-Kit(hi)IL-7Ralpha-) and c-Kit(lo)IL-7Ralpha+. While c-Kit(hi)IL-7Ralpha- progenitors are absent, c-Kit(lo)IL-7Ralpha+ progenitors are abundant in the lymph nodes (LNs).(More)
Incidence of grade II-IV acute graft-versus-host disease (aGVHD) in nonmyeloablative (NMA) transplant recipients remains high. To date, the ideal prophylaxis regimen, which minimizes aGVHD and chronic GVHD (cGVHD), but does not abrogate graft-versus-tumor (GVT) response, has not been described. Because tacrolimus is more potent than cyclosporine (CSA), and(More)
A new system based on 3D digitization with magnetic fields has been developed by our research team. The focus of this study was to evaluate the intratester reproducibility of this technique of measurement. Twenty key morphological parameters were used twice to digitize the fourty five female subjects aged 7 to 23 years. The results of variance analysis(More)
We have developed a new clinical evaluation of the human posture based on 3D digitization with magnetic fields. This 3D postural evaluation displays the relative position of the head, the shoulders and the pelvis. The main purpose is to identify key morphological parameters in order to demonstrate significant differences between 2 groups of subjects.(More)
Current knowledge on the association between back pain and idiopathic scoliosis is often contradictory. The presence, localisation and importance of pain was evaluated for a cohort of 426 adolescents with AIS. Patients were recruited from a scoliosis clinic in a pediatric hospital. A questionnaire and an analogue visual scale graduated from 0 (no pain) to(More)
This retrospective study was conducted to verify the possibility of a relationship between morphological somatotypes and Adolescent Idiopathic Scoliosis (AIS). The sample was composed of 77 adolescent girls presenting Idiopathic Scoliosis. In every case, scoliosis was important enough to necessitate a corrective surgery. The control group (historical type)(More)
