Discussion Muscle tone is the slight tension that is felt in a muscle when it is voluntarily relaxed. It can be assessed by asking the patient to relax and then taking the muscles through a range of motion such as moving the wrists, forearm and upper arm. Muscle strength is the muscle’s force against active resistance. Impaired strength is called weakness or paresis. There are 5 levels of muscle strength. 0 = No muscle contraction detected 1 = Barely detected flicker of contraction 2 = Active movement with gravity eliminated 3 = Active movement against gravity 4 = Active movement against gravity and some resistance ...

What Causes Ataxia?
Discussion Coordination and balance problems are caused by various problems affecting the central and peripheral nervous system. Normal development of a child or weakness of a child are commonly mistaken for true ataxia. Ataxia specifically refers to “…impairment of the coordination of movement without loss of muscle strength.” If it is purely due to abnormalities of the cerebellum then there should be no changes in mental status, sensation or weakness.

What Causes Facial Nerve Palsy?
Discussion Facial nerve palsy has been known for centuries, but in 1821 unilateral facial nerve paralysis was described by Sir Charles Bell. Bell’s palsy (BP) is a unilateral, acute facial paralysis that is clinically diagnosed after other etiologies have been excluded by appropriate history, physical examination and/or laboratory testing or imaging. Symptoms include abnormal movement of facial nerve. It can be associated with changes in facial sensation, hearing, taste or excessive tearing. The right and left sides are equally affected but bilateral BP is rare (0.3%). Paralysis can be complete or incomplete at prese...
