Abstract

Stroke causes neurological, motor and/or sensory sequelae, with hemiparesis being the main one. Hemiparesis is defined as a condition in which the lower and upper limbs on the same side of the body are compromised by paralysis, having a direct impact on mobility, social participation and quality of life of affected individuals, thus, it is extremely relevant. the assessment of the displacement of people with hemiparesis in different environments. The Life Space Assessment (LSA) scale was developed to assess an individual's mobility (short and long distances), and is based on the distance covered, independence of displacement and weekly frequency. Activity monitors are used to measure mobility and their validity has already been proven for the population of people with hemiparesis. The StepWatch Activity Monitor (SAM) is an accelerometer and microprocessor that is placed on the ankle and performs the total step count. There are no studies in the literature that have applied LSA remotely. In addition, there are no studies that correlate LSA with activity monitors such as SAM. The objectives of the study will be to evaluate the reliability of the LSA scale applied remotely and to evaluate the correlation between the LSA scale and the SAM accelerometer applied in patients with hemiparesis. Correlation data between LSA and SAM will be analyzed using Pearson's correlation test. The correlation will be considered: very low (values < 0.26), low (between 0.26 and 0.49), moderate (between 0.50 and 0.69), high (between 0.70 and 0.89) or very high (between 0.90 and -1.00). To assess reliability, the intraclass correlation coefficient (ICC) will be used. The following will be considered: poor (ICC < 0.4); satisfactory 0.4 d ICC < 0.75 and excellent ICC e 0.75.
