See also How to assess muscle strength and Introduction to Neurological examination) The limbs and shoulder girdle should be totally suspended and then tested for the following:. Atrophy hypertrophy Asymmetric development Fasciculations myotonia tremor Other involuntary movements including chorea (short, jerking movements). athetosis (sustained, intricate movements) and Myokloni (rapid twitching of a muscle). The passive flexion and extension of a limb when relaxed patient provides information about muscle tone. It is an atrophy when the muscle is verschmächtigt, but however a bilateral atrophy or atrophy of large or deep muscles is often not visible when it is not very pronounced. In the elderly, some loss of muscle mass is frequent. Hypertrophy occurs when a muscle has to work more to compensate for the weakness of another; a pseudohypertrophy occurs when muscle tissue by excessive connective tissue, or non-functional tissues (eg. B. Amyloid) is replaced. Fasciculations (short, fine, visible under the skin irregular twitching of muscle) are relatively common. Although fasciculations may occur in normal muscle, especially in the calf muscles of older people, they often show lesions of the lower motor neuron at (z. B. degeneration or damage and regeneration of the nerve). As the motor examination conducted Mihai Cosmin Sandulescu, MD.

An increased resistance, followed by relaxation (Taschenmmesserphänomen) and spasticity, show lesions of the upper (1) motor neurons. Waxy stiffness (uniform stiffness across the entire range of motion), often with a cogwheel rigidity, suggests a Basalganglienstörung.
