Table 2 Effect of orthosis on pain scores

From: Orthosis reduces breast pain and mechanical forces through natural and augmented breast tissue in women lying prone

  Pain score Orthosis vs no orthosis Any pain vs no pain
All participants (n = 31)1 Mean (SD) % change vs no orthosis ANOVA; p-value Chi-square; p-value
No orthosis 4.8 (1.9)    
Size-1 1.4 (1.0) -71 <0.0001 0.02
Size-2 0.2 (0.4) -96 <0.0001 <0.0001
Size-3 0 -100 <0.0001 <0.0001
Primary augmentation (n = 18)     
No orthosis 4.7 (1.8)    
Size-1 1.7 (1.0) -64 <0.0001  
Size-2 0.2 (0.4) -96 <0.0001  
Size-3 0 -100 <0.0001  
Reconstruction (n = 3)     
No orthosis 4.3 (0.6)   0.01  
Size-1 1.0 (0) -77   
Size-1 0.3 (0.6) -93 0.006  
Size-3 0 -100   
Natural (n = 7)     
No orthosis 4.0 (1.6)    
Size-1 1.3 (1.1) -68 <0.0001  
Size-2 0.4 (0.5) -90 <0.0001  
Size-3 0 -100 <0.0001  
Lactating (n = 2)     
No orthosis/Size-1/2/3 8/1.5/0/0 -81,-100   
Lumptectomy (n = 1) 9/0/0/0 -100   
TramFlap (n = 1) 1 0/0/0/0 no pain sensation   
  1. Participants experienced significantly less pain with the orthosis compared to no orthosis.
  2. 1The patient with the tram-flap reconstruction did not have any sensation in the breast, therefore did not experience any pain. This patient was excluded from the analysis of all patients.
  3. Ns, not significant; vs, versus.
