Walking pattern in 9 women with hip dysplasia 18 months after periacetabular osteotomy.

Background: Periacetabular osteotomy improves radiographic predictors of osteoarthrosis and diminishes pain and functional impairment. No changes in function quantified by gait analysis have yet been documented. We evaluated the functional outcome of periacetabular osteotomy in relation to gait.

Self-reported nonmusculoskeletal responses to chiropractic intervention: a multination survey.

Objective: To replicate a previous study of nonmusculoskeletal responses to chiropractic intervention and to establish whether such responses are influenced by the country of study, chiropractors' attitudes, and information to patients, patients' demographic profiles, and treatment regimens.

Methods: Information obtained through questionnaires by chiropractors and patients on return visit within 2 weeks of previous treatment from chiropractic practices in Canada, United States, Mexico, Hong-Kong, Japan, Australia, and South Africa. In all, 385 chiropractors collected valid data on 5607 patients.

Walking pattern in adults with congenital hip dysplasia: 14 women examined by inverse dynamics.

Background: Knowledge of the gait dynamics in patients with hip dysplasia may help to understand the consequences of the mechanical changes in the hip.

Patients And Methods: We evaluated the walking pattern of 14 women with hip dysplasia (median age 39 (24-50) years) before periacetabular osteotomy and compared it with a control group of 12 healthy women (median age 35 (24-56) years). Data were collected using five video cameras and two force plates.
