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.

Case ReportsCervical flexion: a study of dynamic surface electromyography and range of motion.
In the comprehensive assessment of painful conditions, dynamic surface electromyography (sEMG) and range of motion (ROM) recordings can provide information regarding muscle spasm, antalgic postures, fear of pain (protective guarding), muscle injury, and disordered movement caused by pain. This study examines ROM and sEMG patterns observed during cervical flexion. ⋯ The results of the study indicate 2 distinct movement patterns associated with upper versus lower cervical flexion and 2 distinct sEMG recruitment patterns. The study suggests that these 2 distinct movements involve 2 distinct cervical segments and are associated with recruitment of different muscle groups. Applied clinical research on the cervical spine should use sEMG recordings to assess both the upper and lower flexion movements as the standard for the study of cervical flexion.

ReviewA proposed etiology of cervicogenic headache: the neurophysiologic basis and anatomic relationship between the dura mater and the rectus posterior capitis minor muscle.
To examine the neurophysiologic basis and anatomic relationship between the dura mater and the rectus capitis posterior minor muscle in the etiologic proposition of cervicogenic headache. ⋯ A sizable body of clinical studies note the effect of manipulation on headache. These results support its effectiveness. The dura-muscular, dura-ligamentous connections in the upper cervical spine and occipital areas may provide anatomic and physiologic answers to the cause of the cervicogenic headache. This proposal would further explain manipulation's efficacy in the treatment of cervicogenic headache. Further studies in this area are warranted to better define the mechanisms of this anatomic relationship.

The Bournemouth Questionnaire: a short-form comprehensive outcome measure. I. Psychometric properties in back pain patients.
Develop and test a short-form comprehensive outcome measure for back pain. ⋯ A reliable, valid, and responsive instrument has been developed for use in back pain patients. It is practical for use in investigations of both the efficacy and effectiveness of back pain treatments.
