A patient has difficulty discerning the position of his body without looking at it. Which term describes the inability to assess the spatial position of the body?

• A. Proprioception
• B. Kinesthesia
• C. Ataxia
• D. Visual neglect

Answer: (A)

Proprioception is the body's sense of where its parts are in space, independent of vision. It relies on receptors in muscles, tendons, and joints and the brain pathways that interpret that information so you can know limb position even with your eyes closed. When a patient cannot discern the position of a body part without looking, this points to impaired proprioception, or a loss of position sense. Kinesthesia is related but specifically refers to sensing movement of a limb (direction and speed), while ataxia describes uncoordinated movements which can arise from various motor or sensory problems. Visual neglect is an attention-related deficit to one side and doesn’t describe the ability to sense body position. Proprioception can be assessed by asking someone to indicate or reproduce a limb’s position with eyes closed.
