MARTINS, Emerson Fachin et al. Comparison between bearing, symmetry, and transfer weight measurements in subjects with or without hemiparesis. Fisioter. Pesqui. [online]. 2011, vol.18, n.3, pp. 228-234. ISSN 1809-2950. http://dx.doi.org/10.1590/S1809-29502011000300005.
Assessment of symmetry and weight-transfer (ASWT) was indicated to relate symmetry and functional activity in the hemiparesis, pointing as the most qualified symmetrical. However, such relationships are not clear and disagree with evidences suggesting asymmetries as strategies for functional strategies. Then, it was proposed to verify the measurements subjectively determined by ASWT agree with measurements calculated by weight-bearing distribution for each foot. It was applied observational study with transversal design for sample of subjects with hemiparesis (n=20) matched by age and gender with controls (n=20). Participants were included in procedures toobtain scores by ASWT and to calculate symmetry ratio (SR) in the weight-bearing between feet by digital scales. The results obtained by ASWT indicated only one subject with hemiparesis presenting symmetry among four subjects identified as symmetric by SR. Besides, the ASWT did not differ overweight toward the affected side and presented significant correlation only when the scores were analyzed with values of SR<1(overweight toward the non-affected side). It was concluded that the ASWT was not agreementto identify weight-bearing distribution compatible with symmetry. Moreover, it did not identify overweight toward the affected side that could to drive to mistaken analysis of the relationship between symmetries and functional performance.
