Results Among women with breast hypertrophy (study group), the average age was 32.2 years (± 8.2 years) and the average age for control group was 32.7 years (± 11.1 years). Mean BMI for study group was 25.8Kg/m2 (± 2.59 Kg/m2 ) and for Figure 1 - Woman with breast Figure 2 - Sacchini’s index = average control group, 22.3 Kg/m2 (±2.87 Kg/m2).

The Numeric Scale (NRS) was employed to assess spinal (8) pain severity . The scale presents scores ranging from GROUP N Average Median Standard Minimum Maximum p-value zero to ten, where the patient determines the level in which her pain is according to the scale (Figure 3).
