Definition Spinal muscular atrophy is a group of inherited diseases that cause progressive muscle degeneration and weakness, eventually leading to death. Alternative Names Werdnig-Hoffmann disease Causes, incidence, and risk factors Spinal muscular atrophy (SMA) is a collection of different muscle diseases. Grouped together, it is the second leading cause of neuromuscular disease. Most of the time, a person must get the defective gene from both parents to be affected. Approximately 4 out of every 100,000 people have the condition. The most severe form is SMA type I, also called Werdnig-Hoffman disease. Infants with SMA type II have less severe symptoms during early infancy, but they become progressively weaker with time. SMA type III is the least severe form of the disease. Rarely, SMA may begin in adulthood. This is usually a milder form of the disease. A family history of spinal muscular atrophy is a risk factor for all types of the disorder.
Alternative Names Tumor - spinal cord Symptoms The symptoms depend on the location, type of tumor, and your general health. Tumors that have spread to the spine from another site (metastatic tumors) often progress quickly. Primary tumors often progress slowly over weeks to years. Tumors in the spinal cord usually cause symptoms, sometimes over large portions of the body. Tumors outside the spinal cord may grow for a long time before causing nerve damage. Symptoms may include: Abnormal sensations , loss of sensation:
Especially in the legs (may be in the knee or ankle, with or without shooting pain down the leg) Cold sensation of the legs, cool fingers or hands, or coolness of other areas May worsen over time Back pain:
Gets worse over time In any area -- middle or low back are most common Is usually severe and not relieved by pain medication Is worse when lying down Is worse with strain, cough, sneeze May extend to the hip, leg, or feet (or arms), or all extremities May stay in the spine Fecal inc...
Every painful spine has a pattern. Do you know your pattern? By knowing when it hurts and when it feels better, you can then figure out how to control your spine pain better. Most spines fit into one of two patterns. Pain that is triggered by extension or pain that is triggered by flexion. Let’s break it down into more detail
Extension-triggered pain presents itself in a variety of ways depending on which part of the spine hurts. If the neck is sensitive to extension, then activities like looking up at a ceiling, the sky or looking through the bottom portion of a bifocal lenses will cause the pain to get worse. This type of pain in the neck is usually related to arthritis in the facet joints of the cervical spine. Improving extension-triggered neck pain is accomplished by tucking the chin closer to the chest, strengthening the anterior neck flexor muscles and avoiding looking up.
Extension-triggered pain in the low back usually feels worse when walking or standing....
