Dr. Twomey showed us, through meticulous dissections that the conventional model of a disc bulging out against a nerve root is not only very unlikely, but that mechanical compression of a nerve only produces paresthesia and numbness. Discs do bulge, but is usually contained within/around the posterior longitudinal ligament. Furthermore a mechanical model that teaches a disc pushes against a ner...

Study Design Retrospective study. Objective Minor trauma, even from a simple fall, can often cause cervical myelopathy, necessitating surgery in elderly patients who may be unaware of their posterior longitudinal ligament ossification (OPLL). The aim of this study is to determine the influence of trauma on the neurologic course in patients who have undergone surgery for cervical OPLL. Methods P...

Traditional measures of respiratory function in children with Duchenne muscular dystrophy (DMD) are based on maximal inspiratory pressure (PImax) and vital capacity (VC). Sniff nasal inspiratory pressure (SNIP) measurements are easily performed by young children with neuromuscular disorders. The clinical value of SNIP in the longitudinal assessment of respiratory weakness remains to be assessed...

PURPOSE To investigate the MR appearance of ossification of the posterior longitudinal ligament (OPLL) of the cervical spine. MATERIALS AND METHODS A retrospective review of MR images and conventional tomograms in 147 patients. RESULTS In the sagittal plane, proton-density images identified the ossified lesions more clearly than did T1- and T2-weighted images. All axial sequences identified...

OBJECT Ossification of the posterior longitudinal ligament (OPLL) can result in significant myelopathy. Surgical treatment for OPLL has been extensively documented in the literature, but less data exist on conservative management of this condition. METHODS The authors conducted a systematic review to identify all reported cases of OPLL that were conservatively managed without surgery. RESUL...

Mechanical properties of cervical spine ligaments are of great importance for an accurate finite element model when analyzing the injury mechanism. However, there is still little experimental data in literature regarding fresh human cervical spine ligaments under physiological conditions. The focus of the present study is placed on three cervical spine ligaments that stabilize the spine and pro...

Women may experience a decline in physical function during menopause. Whether this decline is due to aging or to changes in hormonal status is unknown. The authors performed a longitudinal data analysis on data collected between 1996 and 2001 to determine the effects of menopausal status, age, race, and use of hormone replacement therapy (HRT) on 3-year changes in grip and pinch strength. Parti...

The aim of the current study was to investigate the longitudinal relationship between improvements of synergism and strength of the upper paretic limb and severity of visuo-spatial neglect during the first 52 weeks post-stroke. The longitudinal association between severity of VSN and motor impairment using Fugl Meyer motor score and Motricity Index of the arm was measured in an intensive repeat...

PURPOSE The purpose of this 1-year longitudinal study is to investigate the change in flow experience among occupational therapy students (OTS). METHODS In December 2012, we prospectively recruited 97 OTS from the Department of Occupational Therapy, Kibi International University. To assess flow experience in daily life, we used the Flow Experience Checklist. RESULTS The dataset included 87 ...
