Myotonia congenita is a congenital neuromuscular channelopathy that affects skeletal muscles (muscles used for movement). It is a genetic disorder.The hallmark of the disease is the failure of initiated contraction to terminate, often referred to as delayed relaxation of the muscles and rigidity. [1]
Rigid spine syndrome, also known as congenital muscular dystrophy with rigidity of the spine (CMARS), is a rare and often debilitating neuromuscular disorder.It is characterized by progressive muscle stiffness and rigidity, particularly in the spine, which can severely limit mobility and impact quality of life.
Signs and symptoms of pregnancy are common, benign conditions that result from the changes to the body that occur during pregnancy. Signs and symptoms of pregnancy typically change as pregnancy progresses, although several symptoms may be present throughout. Depending on severity, common symptoms in pregnancy can develop into complications. [1]
During pregnancy the plasma volume increases by 40-50% and the red blood cell volume increases only by 20–30%. [22] These changes occur mostly in the second trimester and prior to 32 weeks gestation. [24] Due to dilution, the net result is a decrease in hematocrit or hemoglobin, which are measures of red blood cell concentration.
This is due to hormone changes throughout their life, especially during pregnancy, where muscles around the pelvis, including piriformis muscles, tense up to stabilize the area for birth. [ citation needed ] [ 70 ] In 2011, out of 263 patients between the ages of 45 to 84 treated for piriformis syndrome, 53.3% were female.
This may be due to weight gain or peripheral oedema (especially in pregnancy), or to a specific condition such as acromegaly, hypothyroidism or scleroderma and psoriasis. Abnormal biomechanics can be associated with nerve compression. Ischiofemoral impingement (where the femur and ischium come too close together) can squeeze the sciatic nerve ...
Learn how muscle memory works, how long it takes to develop, and why it’s crucial for fitness. Plus, tips to train smarter and build strength and muscle faster.
Hypotonia is a state of low muscle tone [1] (the amount of tension or resistance to stretch in a muscle), often involving reduced muscle strength. Hypotonia is not a specific medical disorder, but a potential manifestation of many different diseases and disorders that affect motor nerve control by the brain or muscle strength.
