McGwire, who has missed the last five games with an ailing back, has improved his lower-back mobility and the pain in the region has lessened, the team said.
Biomechanically, a lack of seat back mobility forced individuals to maintain an upright seating posture with increased extensor muscle forces and increased spinal compression.
He gives readers some talking points to brush back Mobility Plan naysayers and deconstructs one of the hot-button issues associated with it: soccer practice.
The measurement of lower back mobility is essential in the assessment of lower back pain including ankylosing spondylitis.
The disease often leads to the formation of spinal syndesmophytes and impaired back mobility, especially in male patients.
Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease, mainly affecting the sacroiliacal joints, vertebrae and intervertebral discs, leading to syndesmophyte formation and impaired back mobility.
Older age and high disease burden, that is, long disease duration, impaired back mobility, syndesmophyte formation and elevated inflammatory parameters, indicated increased risk of osteoporosis.
Methods of assessment were questionnaires, back mobility tests, blood samples, lateral spine radiographs for syndesmophyte grading (mSASSS), DXA of the hip, radius and lumbar spine in anteroposterior (AP) and lateral projections with estimation of volumetric BMD (vBMD).
Male sex, old age, long disease duration, elevated inflammatory parameters, advanced chronic AS-related changes in the spine, and poor back mobility have been identified as risk factors for osteoporosis and vertebral fractures [ 7- 13].
17 The content of the BI questionnaire includes ten activities: feeding; bathing; grooming; dressing; bowels; bladder; toilet use; transfers (bed to chair and back); mobility (on level surfaces); and use of stairs.
