Standard CPR is performed with the person in supine position. Prone CPR or reverse CPR is CPR performed on a person lying on their chest, by turning the head to the side and compressing the back.
Non-spinal structural causes of weak legs may include sacroiliac joint pain syndromes and piriformis syndrome. Non-sciatica related sources of weakness in the legs may include diabetes, peripheral neuropathy and various circulatory and neurological conditions.
Leg weakness can occur as part of a generalized feeling of weakness all over your body, or it may develop in one or both legs. True weakness occurs when the muscles lose their strength, but people often perceive that their muscles are weak when they feel ill or tired. In these cases there is not a true loss of muscle function. The sudden onset of muscle weakness can be a sign of stroke, a potentially life-threatening condition in which part of the brain is deprived of oxygen. This article focuses on conditions that cause a true loss of strength in the leg muscles. Among the most common causes for leg weakness is sciatica, problems with the spinal cord that lead to pinching or compression of the nerves as they exit the spinal cord through the holes between the vertebrae of the backbone.
