TI  - Influence of scapular position on the pressure pain threshold of the upper 
      trapezius muscle region.
PG  - 226-32
AB  - A position of scapula depression will maintain the upper trapezius muscle region 
      in a lengthened position, causing excessive strain. This strain could lead to 
      peripheral nociceptive nerves sensitization in the affected area, changing the 
      pressure pain threshold (PPT). Thus, people with a faulty alignment of scapular 
      depression may have lower PPT levels in the upper trapezius region when compared 
      to subjects with normal vertical scapular position. The purpose of this 
      double-blind study was to assess the influence of scapular position on the PPT of 
      the upper trapezius region in a young healthy population. Fifty two physical 
      therapy students of the Catholic University of Minas Gerais-PUC-Minas, Brazil, 
      with normal shoulder (NS group, n=26, 6 men and 20 women) or depressed shoulder 
      (DS group, n=26, 6 men and 20 women) volunteered to participate in this study. An 
      electronic pressure algometer was used to measure the PPT on the upper trapezius 
      muscle region. The results showed a significant difference between groups, with 
      the DS group (19.0+/-9.0 N/cm(2)) demonstrated lower mean PPT values when 
      compared to NS group (26.1+/-9.6 N/cm(2)) (p<0.01). Our results showed that 
      healthy young subjects with depressed scapula position had significant lower 
      upper trapezius PPT values when compared to subjects with normal scapula 
      position.
