sensation
peripheral nervous system damage or sensory loss due to CNS damage
CNS system
deficits in proprioception and stereognosis
PNS injury
- deficits in touch pressure awareness and 2-point discrimination
- loss occurs in order: light touch, cold, heat, pain
carpal tunnel syndrome is a
median nerve entrapment causing sensory motor changes in median nerve distribution area
symptoms of damaged peripheral nerves correspond to
area of neural distribution (dermatome)
impairment of single spinal cord nerve root impacts sensation on
ipsilateral side over corresponding area served by that nerve root
in assessment, always prioritize delineation of
protective sensation to insure patient safety
clinicians strive to create accurate map of intact and
impaired sensory areas using sensory evaluation techniques
mechanoreceptors
respond to touch, pressure stretch and vibration; stimulated by mechanical deformation
chemoreceptors
respond to cell injury; stimulated by substances that the injured cells release
thermoreceptor
respond to stimulation of heat and cooling
sensory evaluation findings summarized as
- intact
- impaired
- absent
impaired
patient detect some, not all, stimuli or perception of stimulus differs from intact skin area
absent
total loss of sensation or inability to detect specific sensory modality
sensory documentation includes
- test type
- skin area tested
- screening score response
touch threshold testing with monofilaments use
color codes on drawing of tested body part
assessments
- proprioception
- stereognosis
- touch localization
choosing intervention for sensory impairment
- findings of discomfort with touch (hypersensitivity) suggest need for desensitization intervention
- sensory reeducation interventions (passive and active sensory training) provided for patients with some sensation and potential for more
compensatory intervention for sensory impairment primary goal
education to avoid further injury
compensatory intervention for sensory impairment secondary goal
teach patient to compensate for absent sensation
