Muscle weakness can be categorised into various patterns to assist with the differential diagnosis. Reduced grip strength, weakness in wrist flexion or extension, diminished plantar flexion strength, and foot drop are common features of distal weakness. Patients with this pattern struggle to walk on their heels or toes. Foot drop can be identified by resisting the patient's attempt to dorsiflex the ankle.
