The epidemiology of cerebral palsy: incidence, impairments and risk factors.

Purpose: Describing the epidemiology of cerebral palsy (CP), its impairments and risk factors.

Method: Literature review 1965-2004. Search terms: Cerebral palsy, incidence, prevalence, impairments, risk factors.

Reliability of tendon excursion measurements in patients using a color Doppler imaging system.

Purpose: The purpose of this study was to assess the test-retest reliability of tendon excursion measurements with color Doppler imaging in patients with flexor tendon injuries following a modified Kleinert protocol.

Methods: One observer performed repeated measurements at 3 different time periods in 13 patients with flexor tendon injuries, following a modified Kleinert protocol. The intraclass correlation coefficient (ICC), the standard error of measurement (SEM), and related indices of measurement error were calculated.

The prognostic value of asymmetric laxity of the sacroiliac joints in pregnancy-related pelvic pain.

Study Design: Prospective cohort study.

Objective: To determine the prognostic value of asymmetric laxity of the sacroiliac joints during pregnancy on pregnancy-related pelvic pain postpartum.

Summary Of Background Data: In a previous study, we observed a significant relation between asymmetric laxity of the sacroiliac joints and moderate to severe pregnancy-related pelvic pain during pregnancy.

Reliability of sacroiliac joint laxity measurement with Doppler imaging of vibrations.

We developed a noninvasive technique, referred to as Doppler imaging of vibrations (DIV), to measure laxity of the sacroiliac joint (SIJ). The purpose of this study was to examine the reliability of SIJ laxity measurements. A total of 10 healthy women (mean 29.
