The aim of the present study was to evaluate the resting and working pressures associated to a restrain mechanism, in patients suffering from lymphedema of the upper limbs, postbreast cancer treatment, whilst performing occupational and day-to-day self-care activities. Six female patients under treatment of lymphedema due to surgical, radiotherapeutic and chemotherapeutic treatment of breast cancer, in the age group between 32 and 76 years (mean 54 years old, ± 31.11) were selected. A compression sleeve of “gorgurão” (cotton-polyester material) was applied as a restrain mechanism. The occupational and daily personal care activities evaluated were those common to all participants. These activities included washingup, cooking in a small pan, sweeping the floor using the affected arm, brushing the teeth, brushing the hair, washing small items of clothes, ironing clothes and making the bed. For statistical analysis, mean and standard deviation between resting pressures and minimum and maximum working pressures were determined. The two-tailed student t-test and variance analysis were used for repeated measurements. The Bonferroni limit was used in the analysis of the variables to calculate the alpha error, with a value of 5%, considered statistically significant. All of the analyzed activities associated to the “gorgurão” compression sleeve generated both resting and working pressures (p <0.005). In conclusion, the occupational daily life tasks used in the present study generate resting and working pressures and can be used as a form of treatment of the lymphedema.
