Beck's syndrome, also known as Beck's paralysis or Becker muscular dystrophy, primarily affects the motor pathways in the nervous system, leading to motor impairments. However, it does not impact all sensory pathways.

In this syndrome, the senses that remain intact are touch and proprioception. Touch refers to the ability to perceive contact with the body or stimuli affecting skin receptors, while proprioception is the sense that allows individuals to perceive the position, movement, and balance of their body parts without using vision. This preservation of touch and proprioception is significant, as it allows those affected to maintain a sense of their body's spatial orientation and interact with their environment despite their motor difficulties.

Other sensory modalities, such as taste, smell, vision, auditory perception, pressure, and temperature, can be affected due to the central or peripheral nerve damage associated with the condition but are not spared in the same way that touch and proprioception are. This differentiation highlights the specific aspect of sensory preservation in Beck's syndrome, providing a clearer understanding of the sensory profile of the affected individuals.
