The use of backward stepwise multiple correlations highlighted the interaction between several body parameters and their relation to standing stability in both able-bodied girls and scoliotic subjects. The scoliotic group displayed a much larger number of correlations between standing stability and body posture parameters than the nonscoliotic group. Standing imbalance was related to altered body posture parameters measured in the frontal and horizontal planes only. Although the correlation coefficients were relatively high, factors other than body posture parameters appeared related to standing imbalance in adolescent idiopathic scoliosis. These findings support the concept of either a primary or a secondary dysfunction in the postural regulation system of scoliotic subjects.

Perturbations in below-knee amputee gait affected the hip muscle powers on the amputated side in all three planes, although the hip frontal plane balance was modified in the sound limb.

Different postural responses seem to be dependent on body somatotypes. The endomorphic AIS girls had a larger sway area than their able-bodied counterparts while maintaining a similar center of pressure position. The AIS ectomorphic girls had a tendency to lean further back than a comparable able-bodied group. This could be emphasizing a hypokyphotic trunk attitude and increasing the risk of spinal deformity progression. The AIS mesomorphic subjects characterized by a large muscular and bony structure had a tendency to position their center of mass more to their right, indicating less postural adaptability and a stiffer trunk.

The aim of our study was to compare rifle shooters' performance between two groups of expert shooters, one trained with a neurofeedback method and the other not trained. The study design employed a pretest-posttest design with an untreated control group (nonrandomized). The sample included 24 national and provincial shooters. Shooting performance was studied based on 6 indicators via a device called ''Scott,'' and paired and independent t tests were performed with corrections for multiple comparisons. A significant improvement was found for the neurofeedback group for the mean of shot results before and after the training (p ¼ .001), but no other improvements were found (all ps > .05). In the control group, no differences were found on any of the study indicators (all ps > .05). There was a significant difference between mean discrepancies of shot results between the two groups (p ¼ .01), whereas there were no such differences in any of other the indicators (all ps > .05). Neurofeedback can be suggested as a method to improve rifle shooters' performances.
