How does motor neuropathy mainly present in patients?

1. Increased sweating and temperature regulation

2. Muscle atrophy and foot deformities

3. Tingling in the hands and feet

4. Excessive fatigue and weakness

The correct answer is: Muscle atrophy and foot deformities

Motor neuropathy primarily affects the motor nerves responsible for controlling muscle movements, leading to a range of physical manifestations. In patients with motor neuropathy, one of the most prominent signs is muscle atrophy, which occurs when the muscles do not receive adequate signals from the nerves to contract effectively. This lack of stimulation may lead to a decrease in muscle mass and strength over time. Foot deformities can also arise as a result of muscle atrophy. When the muscles that support the structure of the foot weaken, it can lead to various deformities, including high arches or flat feet, which can cause further complications, such as ulcers or difficulty in mobility. While the other options highlight different sensory or systemic issues, they do not specifically illustrate the characteristic presentation of motor neuropathy, which is fundamentally linked to muscle control and strength. Thus, focusing on muscle atrophy and related deformities accurately captures the essence of how motor neuropathy primarily presents in patients.
