“…26 Silva et al (2019) evaluated amputees and observed that the active change in posture, from a sitting to a standing position, lead to an activation of autonomic and sympathetic modulation within the expected behavior of the individuals. 6 Our results showed that using the orthostatic device did not generate any interference in the sympathetic and parasympathetic nervous system parameters measured, indicating that the use of the device for 90 minutes did not influence the perception of stress or physical effort generated by the prolonged standing position beyond what was expected by the volunteers.…”

“…5 Thus, amputees seem likely to present a functional imbalance in the autonomic nervous system as compared to healthy and non-amputee individuals, with higher heart rate, blood pressure, plasma norepinephrine, and sympathetic nerve activity values. 5,6 Furthermore, limb amputation contributes to psychosocial alterations, leading to increased consumption of alcohol, smoking, and reduced physical activity, with obesity as a possible consequence. 7 The physical changes occur mainly due to the asymmetry caused by the absence of the sustaining limb, the dependence on an artificial limb (prosthesis) to help support the body, and muscle control, activation, and strength deficiencies that can lead to compensatory hip, pelvis, and trunk movements.…”

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.
