Group D - S-curve with upper spine (C2-C4) showing lordosis and lower spine (C5-7) showing kyphosis
Group D - S-curve opposite to Group D with upper spine kyphotic and lower spine lordotic.
Why is spinal posture important
Alterations in spinal posture via translatory motions also affect the kinematics of the spine.
What is the difference between men and women in seated positions in terms of lumbar posture and location on the seat itself.
In general females demonstrated more pelvic anterior tilt, less lumbar flexion and less overall trunk flexion than the males. In chairs with back rests males tended to lean against the back rest while females sat closer to the front part of hte seat.
What is the problem with kyphosed sitting postures?
They can lead to cumulative damage to soft tissues of the spine.
What does the research say about posture and shoulder ROM
Changing posture causes a significant increase in the ROM in shoulder flexion and abduction in the plane of the scapula. Changing posture did not have an effect on the intensity of pain but did affect the point in the range of shoulder elevation at which the pain occurred (significantly higher).
Does thoracic posture have an affect on the kinematics of the scapula?
Yes, increased thoracic kyphosis significantly alters the kinematics of the scapula during humeral elevation.
