Spondylotic cervical myelopathy (SCM) is the most frequent cause of cervical myelopathy in the population over 50 years of age [1-3] and even over 15 years of age (SCM 23.6%, spinal tumor 16.4%, multiple sclerosis 9.1%, after magnetic resonance imaging (MRI) 17.8%, motor neuron disease 4.1%) [4]. What makes SCM so clinically loaded is its potentially malignant natural history (including the deleterious effect of small injuries to the cervical spine or even prolonged hyperflexion or hyperextension [5] at the hairdresser, dentist, or during general anesthesia [6]) and the potentially calamitous results of surgery [7,8]. The treatment of SCM is a matter of controversy in the literature. Surgery is a logical response to the stenotic process, but no good evidence exists that decompressive surgery with anterior or posterior approach can improve the clinical outcome for the victims of this disease, particularly in the long term. Prospective studies of the surgical approach to this disease are generally lacking. The results of our randomized prospective study did not show any important difference between the outcome for patients with mild and moderate forms of SCM treated surgically or conservatively over a 36-month period [9,10]. Neither of these methods can prevent an unfavorable (but not necessarily disastrous) course for a proportion (20-30%) of patients. The possibility remains (alongside efforts to improve our therapeutic armamentarium) of analyzing a group of patients responding positively or negatively to conservative and surgical treatment and to assess the prediction factors for good or bad outcomes, i.e., to find measures enabling the choice of patients who may profit from the conservative or from the surgical approach.
Spine
Published in David A Lisle, Imaging for Students, 2012
Occasionally, a vertebral metastasis may expand into the spinal canal and compress the spinal cord causing an acute myelopathy. Clinical features of myelopathy include:Motor problems in the legs leading to difficulty with walkingSensory disturbances; a band-like sensation around the abdomenVoiding difficulties.
Body activity grading strategy for cervical rehabilitation training
Published in Computer Methods in Biomechanics and Biomedical Engineering, 2023
The symptoms of cervical spondylotic myelopathy include neck pain, stiffness, cervical vertigo, hand numbness, shoulder-back constriction, nausea, and vomiting. It is agreed that active cervical rehabilitation training is a useful means of treatment or relief (Hurwitz et al. 2008; Dedering et al. 2018), which usually involves strengthening, stretching, and stabilizing physical therapy (PT) exercises (Gross et al. 2016). To investigate the performance of these exercises, head rotation must be tracked accurately. In this paper, IMU (inertial measurement unit) sensor is used as the data collection unit. As depicted in Figure 1, an IMU sensor is attached at the user’s forehead by following the sensor placement principles mentioned in Qiu et al. (2022), which is a widely accepted setup in previous research (Ionut-Cristian and Dan-Marius 2021).
