Standardized initial head position in cervical range-of-motion assessment: reliability and error analysis.
To assess the clinical reliability and precision of the OSI CA-6000 Spinal Motion Analyzer for measurement of range of motion in cervical spines of pain-free subjects by using a novel procedure designed to minimize variability and quantitatively evaluate sources of errors. ⋯ By using our modifications to the accessories and standardization of subject position, the CA-6000 is a highly precise and reliable instrument for measuring active cervical motion about the 3 Cartesian axes. Individuals can repeat the same patterns of motion in sequential trials on the same day with very little variation. Ease of repetitious measurement without examiner intervention contributes to the instrument's ability to obtain highly reliable data. Changes in instrument placement or subject body posture between trials do not give rise to systematic errors. Design of the instrument for flexion-extension could be improved.

Case ReportsPelvic stress fracture: assessment and risk factors.
To discuss the case of a patient with a pelvic stress fracture and the differential considerations among patients presenting with hip and/or groin pain. ⋯ When predisposing factors are present, such as osteoporosis and rheumatoid arthritis, pelvic stress fracture should be suspected in patients with groin or hip-area pain. However, because pelvic stress fractures are relatively rare, radiographic studies are often postponed, making diagnosis difficult.
