Upper motor neuron lesions
Upper motor neuron lesions are caused by degeneration of the upper motor neurons. Patient may present with increased in tone of the upper and lower limbs. There will be reduced in power of both upper and lower limbs. The reflexes are increased. Ankle clonus and up going plantar may occur. Contracture may present.
The treatment of upper motor neuron lesions may include physiotherapy and occupational therapy.
Lower motor neuron lesions.
Lower motor neuron lesions may present with reduced in tone, reduced in the power of the upper and lower limbs, increased in reflexes and wasting as well as fasciculation. Lower motor neuron lesions may also present with bulbar symptoms which carries worst prognosis. Bulbar symptoms may include indistinct nasal speech, paralysis of the palate and wasted fasciculation of the tongue.
