  3. 3. o Changes in mental status. o Slowed reflexes. o Loss of balance. o Dizziness and syncope. o Slight tremors. o Difficulty with fine motor movement. o Changes in sleep patterns, such as decreased total sleep with earlier risings. o Increased susceptibility to hypothermia and hyperthermia. Neurological System
  4. 4. Musculoskeletal System o Posture and stature changes causing a decrease in height. o Kyphosis of the dorsal spine. o Muscle mass decreases and muscles atrophy. o Joint capsule components deteriorate. o Decreased mobility, range of motion, flexibility and stability. o Increased stiffness. o Decrease in physical strength. o Decrease in muscular coordination. o Change of gait, with shortened step and wider base. o Increased brittleness of the bones. o Decrease in deep tendon reflexes.
  5. 5. Cardiopulmonary System o Energy and endurance diminish. o Lowered tolerance to exercise. o Decreased stretch and compliance of the chest wall. o Decreased rib mobility and lung tone. o Decreased strength and function of respiratory muscles. o Decreased depth of respirations and oxygen intake. o Decreased ability to cough and expectorate sputum.
