The Complex Movements of the Knee Complex

The Knee’s Position in the Squat This overview of the ‘Complex Movements of the Knee Complex’ is not intended to tell you the right way to squat, but rather to show what is happening with the anatomy during movement and why. It also will show you how to read/name the movements with observation from the […]

People With Chronic Neck Pain Walk With a Stiffer Spine

Authors: Deborah Falla, PT, PhD Study Design Case-control. Background People with chronic neck pain present a number of sensorimotor and biomechanical alterations, yet little is known about the influence of neck pain on gait and motions of the spine during gait. Objective To evaluate the spine kinematics and gait characteristics in people with non-specific chronic […]

Impact of lumbar spine posture on thoracic spine motion and muscle activation patterns

Hum Mov Sci. 2014 Oct;37:1-11. doi: 10.1016/j.humov.2014.06.003. Epub 2014 Jul 12. Nairn BC, Drake JD. Abstract Complex motion during standing is typical in daily living and requires movement of both the thoracic and lumbar spine; however, the effects of lumbar spine posture on thoracic spine motion patterns remain unclear. Thirteen males moved to six positions […]

Radiosteriometric analysis of movement in the sacroiliac joint during a single-leg stance in patients with long-lasting pelvic girdle pain

Clin Biomech (Bristol, Avon). 2014 Apr;29(4):406-11. doi: 10.1016/j.clinbiomech.2014.02.002. Epub 2014 Feb 16. Kibsgård TJ Abstract BACKGROUND: Chamberlain’s projections (anterior-posterior X-ray of the pubic symphysis) have been used to diagnose sacroiliac joint mobility during the single-leg stance test. This study examined the movement in the sacroiliac joint during the single-leg stance test with precise radiostereometric analysis. […]
