Interexaminer Reliability of the Hip Extension Test for Suspected Impaired Motor Control of the Lumbar Spine

Outcome of Pregnancy-Related Lumbopelvic Pain Treated According to a Diagnosis-Based Decision Rule: A Prospective Observational Cohort Study

“…It is based on 3 questions of diagnosis 8 (Fig 1) a. Dynamic instability of the lumbar spine or pelvis: this is thought to arise from impairment of the motor control system 22 and was evaluated with examination procedures such as the hip extension test, 23 the segmental instability test, 24 and the active straight leg raise test. 25 b.…”

Correlation of Lumbar-Hip Kinematics Between Trunk Flexion and Other Functional Tasks

“…[5][6][7] Moreover, disorders of the lumbar-hip complex have a demonstrably significant effect on movement velocity, both at the hip and at the lumbar spine. [8][9][10][11][12][13] This has been determined for cardinal ROM (lumbar flexion/extension) and in more functional movements such as lifting an object from the floor, a commonly reported daily activity.…”

An Investigation of Neck Muscle Activity in Asymptomatic Participants Who Show Different Lumbar Spine Motion Patterns During Prone Hip Extension

“…Although multiple examiners assisted with this process in our study, the interexaminer reliability of the classification method used in our study has been shown to be good. 10 After confirming the details of this classification method in a personal communication with the reliability study's first author, our examiners underwent a training session to further maximize the consistency of their findings between participants. During this session, they observed volunteers perform the test and discussed their findings to achieve a consensus regarding the specific procedure to use as well as the criteria for classifying participants as positive and negative, in the subsequent data collection sessions.…”

“…10 It was suggested that instead of using the test to assess the motor patterns during the movement, clinicians should observe for 3 specific abnormal lumbar spine motion patterns, namely: (1) rotation of the lumbar spine such that the spinous processes a Assistant Professor and CCRF Research Chair in Neuromusculoskeletal Health, Faculty of Kinesiology and Health Studies,…”

“…10 It was suggested that instead of using the test to assess the motor patterns during the movement, clinicians should observe for 3 specific abnormal lumbar spine motion patterns, namely: (1) rotation of the lumbar spine such that the spinous processes appeared to move toward the side of hip extension, (2) a lateral shift of the lumbar spine toward the side of hip extension, and (3) extension of the lumbar spine. Importantly, the results of this study showed good reliability in classifying patients with low back pain as "positive" or "negative" based on the presence or absence (respectively) of these abnormal motion patterns.…”
