OBJECTIVES: To investigate whether distinct sensory phenotypes were identifiable
in individuals with nonspecific arm pain (NSAP) and whether these differed from
those in people with cervical radiculopathy. A secondary question considered
whether the frequency of features of neuropathic pain, kinesiophobia, high pain
ratings, hyperalgesia, and allodynia differed according to subgroups of sensory
phenotypes. DESIGN: Cross-sectional study. SETTING: Higher education institution.
PARTICIPANTS: Forty office workers with NSAP, 17 people with cervical
radiculopathy, and 40 age- and sex-matched healthy controls (N=97).
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Participants were assessed
using quantitative sensory testing (QST) comprising thermal and vibration
detection thresholds and thermal and pressure pain thresholds; clinical
examination; and relevant questionnaires. Sensory phenotypes were identified for
each individual in the patient groups using z-score transformation of the QST
data. RESULTS: Individuals with NSAP and cervical radiculopathy present with a
spectrum of sensory abnormalities; a dominant sensory phenotype was not
identifiable in individuals with NSAP. No distinct pattern between clinical
features and questionnaire results across sensory phenotypes was identified in
either group. CONCLUSIONS: When considering sensory phenotypes, neither
individuals with NSAP nor individuals with cervical radiculopathy should be
considered homogeneous. Therefore, people with either condition may warrant
different intervention approaches according to their individual sensory
phenotype. Issues relating to the clinical identification of sensory
hypersensitivity and the validity of QST are highlighted.
