Somatosensory changes
The somatosensory system consists of sensory information from receptors in the muscle, tendons and joints that provide feedback regarding joint position sense, movement (kinesthesia) and touch which commonly referred to as proprioception demonstrated that position sense of knee and metatarsophalangeal joints decrease with advanced age. found that adults aged 50 to 85 years had low ability to detect directional change of hip, knee and ankle movements. The loss of proprioceptive fibers may contribute to the postural dysfunction that is observed in elderly. This affects the coordination ability associated with activities in daily life of the elderly.
