significant correlation was also found between the change of TK Study Design. A retrospective study. Objective. To explore the relationship between the change of lumbar lordosis (LL) and thoracic kyphosis (TK) in AIS patients after correction surgery. Summary of Background Data.

متن کاملRelationships between lumbar lordosis, pelvic tilt, and abdominal muscle performance.
The purpose of this study was to examine the relationships between measurements of lumbar lordosis, pelvic tilt, and abdominal muscle performance during normal standing. In addition, the reliability of the measurements used in this study was examined. Measurements of lumbar lordosis, pelvic tilt, and abdominal muscle performance were taken of 31 healthy adults aged 20 to 33 years. Each measurem...
متن کاملStrength gains through lumbar lordosis restoration.
OBJECTIVE To test the hypothesis that restoring the lumbar lordosis will increase a patient's voluntary muscular strength and decrease back pain symptoms. CLINICAL FEATURES A patient was diagnosed with mechanical low back pain. The initial radiographic study revealed a loss of the lumbar lordosis. The patient determined his maximum bench press prior to the treatment program. The treatment out...
متن کاملInfluence of pelvic incidence-lumbar lordosis mismatch on surgical outcomes of short-segment transforaminal lumbar interbody fusion
BACKGROUND The importance of pelvic incidence-lumbar lordosis (PI-LL: PI minus LL) mismatch is emphasized in long-segment fusion for adult spinal deformity; however, there are few studies evaluating the influence of PI-LL on surgical outcomes after short-segment fusion. In this study, we have examined the effects of PI-LL mismatch on surgical outcomes of short-segment lumbar intervertebral fusi...
متن کاملThe Lumbar Lordosis in Males and Females, Revisited
BACKGROUND Whether differences exist in male and female lumbar lordosis has been debated by researchers who are divided as to the nature of variations in the spinal curve, their origin, reasoning, and implications from a morphological, functional and evolutionary perspective. Evaluation of the spinal curvature is constructive in understanding the evolution of the spine, as well as its pathology...
