Disuse is a common cause of muscle atrophy and can be local (due to injury or casting) or general (bed-rest). The rate of muscle atrophy from disuse (10–42 days) is approximately 0.5–0.6% of total muscle mass per day although there is considerable variation between people. [5]
The damage to nerves supplying specific muscles may cause muscle twitching (fasciculations) in addition to the weakness. It is sometimes associated with weight loss. [2] Diabetes most commonly causes damage to the long nerves that supply the feet and lower legs, causing numbness, tingling and pain (diabetic polyneuropathy). Although these ...
In general, distal hereditary motor neuropathies affect the axons of distal motor neurons and are characterized by progressive weakness and atrophy of muscles of the extremities. [1] It is common for them to be called "spinal forms of Charcot-Marie-Tooth disease (CMT)", because the diseases are closely related in symptoms and genetic cause.
An initial diagnosis of PMA could turn out to be slowly progressive ALS many years later, sometimes even decades after the initial diagnosis. The occurrence of upper motor neuron symptoms such as brisk reflexes, spasticity, or a Babinski sign would indicate a progression to ALS; the correct diagnosis is also occasionally made on autopsy.

Pressure on the nerves can cause tingling sensations, numbness, pain, weakness, muscle atrophy and even paralysis of the affected area. In normal individuals, these symptoms disappear quickly, but in sufferers of HNPP even a short period of pressure can cause the symptoms to occur. Palsies can last from minutes or days to weeks or even months ...
When you’re working up a sweat, your feet likely get less attention than larger muscle groups (we’re looking at you, core workouts!), but when you have flat feet—which, according to some ...
The disease is characterized by slowly progressive weakness and wasting of both proximal muscles (located on or close to the torso) and distal muscles (close to hands or feet), most apparent in the finger flexors and knee extensors. [3] IBM is often confused with an entirely different class of diseases, called hereditary inclusion body ...
Signs and symptoms of peroneal nerve palsy are related to mostly lower legs and foot which are the following: [3] Decreased sensation, numbness, or tingling in the top of the foot or the outer part of the upper or lower leg; Foot drops (unable to hold the foot straight across) Toes drag while walking; Weakness of the ankles or feet; Prickling ...
