In general,<unk>  neuropathy will result in symptoms in a specific anatomic distribution, affecting the little finger, the<unk>  half of the ring finger, and the intrinsic muscles of the hand. The specific symptoms experienced in the characteristic distribution depend on the specific location of<unk>  nerve impingement. Symptoms of<unk>  neuropathy may be motor, sensory, or both depending on the location of injury. Motor symptoms consistent of muscle weakness; sensory symptoms or paresthesias consist of numbness or tingling in the areas innervated by the<unk>  nerve. Proximal impingement is associated with mixed symptoms, as the proximal nerve consists of mixed sensory and motor innervation. Distal impingement is associated with variable symptoms, as the<unk>  nerve separates near the hand into distinct motor and sensory branches. In cubital tunnel syndrome (a proximal impingement), sensory and motor symptoms tend to occur in a certain sequence. Initially, there may be numbness of the small and<unk>  fourth finger which may be transient. If the impingement is not corrected, the numbness may become constant and progress to hand weakness. A characteristic resting hand position of<unk>  claw," where the small and ring fingers curl up, occurs late in the disease and is a sign of severe neuropathy. By contrast, in Guyon's canal syndrome (distal impingement) motor symptoms and claw hand may be more pronounced, a phenomenon known as the<unk>  paradox. Also the back of the hand will have normal sensation.
