ABSTRACT
Introduction:
Lower limb amputation affects mainly economically active young adults, causing great socio-economic impact due to impaired work capacity, socialization, and quality of life. Thus, the use of orthostatic devices could make reintegration of the individual back into the work environment possible.
Objective:
To evaluate the immediate effect of using a postural elevation device on physiological parameters and plantar pressure levels in amputees who practice physical activity.
Methods:
Sociodemographic and perceived sleep quality data were collected from 14 adults of both sexes with lower limb amputations, who practice physical activity. The participants were placed in postural elevation equipment for a period of 90 minutes with monitoring of physiological parameters such as blood pressure, heart rate, and oxygen saturation. Parameters related to the autonomic nervous system and plantar pressure levels were also evaluated. Data were also collected during recovery at 15- and 30-minute intervals after using the device. Data analysis was performed using two-way ANOVA or a mixed-effects model with Sidak's multiple comparisons test.
Results:
For all cardiovascular parameters (p>0.05) analyzed, the activation level of the autonomic nervous system (p>0.05), and plantar pressure (p>0.05), no evidence of differences was observed during use of the orthostatic device in all evaluated periods.
Conclusion:
The use of postural elevation equipment for 90 minutes does not generate, as an immediate effect, changes in physiological parameters and postural control in amputees who practice physical activity. Level of evidence II; Therapeutic studies – investigation of treatment results. Clinical relevance statement .
