Individuals with sensory modulation disorder (SMD) demonstrate abnormal
responses to naturally occurring stimuli in a manner that interferes with daily
life activities. This study is the first study applying quantitative sensory
testing to characterize the somatosensory sensitivity of adults with SMD. METHOD:
One hundred and fifty one adults (68 males and 83 females) were tested comparing
91 SMD to 60 SMD-free, control individuals. Group placement (SMD vs. SMD-free)
was determined using the Sensory Responsiveness Questionnaire (SRQ). Sensory
detection thresholds for skin warming, cooling, punctate dynamic tactile
sensation, vibration and thermal pain thresholds for heat and cold stimuli were
determined at several body sites. Pinprick pain and prickliness were also
assessed, as well as the duration and intensity of the after-sensations of
prickliness and pain evoked by the prickly stimuli. RESULTS: Compared to control
adults, individuals with SMD showed significantly higher pain intensity to
prickle stimuli, marginally higher pain intensity to pinprick and hypoesthesia to
punctate dynamic tactile sensation at one of two sites tested. CONCLUSIONS: These
results are in line with our previous study that investigated children with SMD
using the same stimuli, and found similar results. We suggest a CNS involvement
as the underlying mechanisms in SMD.
