  • Data are mean (SD) unless otherwise indicated.

  • Statistically significant results (i.e., P < 0.05) appear in boldface type.

  • CDT, cold detection threshold; CPT, cold pain threshold; DMS, dynamic mechanical sensitivity; HPT, heat pain threshold; MDT, mechanical detection threshold; MPS, mechanical pain sensitivity; MPT, mechanical pain threshold; PHS, paradoxical heat sensation; TSL, thermal sensory limen; VDT, vibration detection threshold; WDT, warm detection threshold.

  • * P values for χ2 test.
