Do your knees feel wobbly or are your legs giving way? If you answered yes to either one of these questions, then you might be experiencing a condition known as Arthrogenic Muscle Inhibition. That’s a fancy way to say that the muscle weakness is caused by joint arthritis, injury and pain.
As a protective mechanism, the nervous system has reflexes that shut down muscle activity in order to protect the injured body part. In the case of an injured knee, ankle or other joint, doctors have observed significant muscle deactivation in response to joint swelling, pain, and arthritis. 1
In response to knee injury, surgery or arthritis, the quadriceps muscles become very weak. Even the hamstring and buttocks muscles are weakened in order to protect the knee. In response to an ankle injury or other painful process, the lower leg muscles in the calf start to lose their power. Researchers are even able to duplicate this arthrogenic muscle response by simulating joint swelling a...
Now that you are seated comfortably with improved posture , how do you get up? The sit-to-stand maneuver is critical for performing activities of daily living like toileting and getting out of bed. Besides, sitting all day is not good for the body. However, muscle weakness and pain can create a serious roadblock to arising from a seated position. With some simple strategies, you might be able to stand up more comfortably.
1. Create an Adequate Base of Support : Two legs are better than one leg, three legs are better than two legs, and four legs... well, you get the picture. With an adequate base of support, this stable platform can be the launching point for you to maneuver from a seated position to a standing position. While seated, look at both feet and make sure to place them at shoulders width apart. If the legs are too close together, then the two become one and more unstable. Two legs may not be enough for some people. Sometimes, a hand placed ...
Alternative Names Muscular dystrophy - limb-girdle type (LGMD) Symptoms Typically, the first sign is pelvic muscle weakness (difficulty standing from a sitting position without using the arms, difficulty climbing stairs). The weakness starts in childhood to young adulthood. Other symptoms include: Abnormal, sometimes waddling, walk Joints that are fixed in a contracted position (late in the disease) Large and muscular-looking calves (pseudohypertrophy), which are not actually strong Loss of muscle mass, thinning of certain body parts Low back pain Palpitations or passing-out spells Shoulder weakness Weakness of the muscles in the face (later in the disease) Weakness in the muscles of the lower legs, feet, lower arms, and hands (later in the disease) Signs and tests Blood creatine kinase levels DNA testing Echocardiogram or ECG Electromyogram (EMG) testing Muscle biopsy
