No. 305 Energy Expenditure and Walking Speed in Lower Limb Amputees: An Old Problem Revisited Again

Introduction Amputations cause functional, musculoskeletal and cardiovascular alterations and, the more proximal the amputation, the larger the alterations. Objectives To observe the effect of using lower limb prosthetics and that of gait speed on heart rate (HR), blood pressure (BP), oxygen consumption (VO2) and energy cost (EC) during gait in traumatic lower limbs amputees. Materials and methods The sample was composed of 30 men with unilateral amputations, 10 transfemoral and 10 transtibial, compared to 10 people with no amputations. All of them selected a pleasant walking speed (PWS) on the treadmill, and two other speeds were calculated, 20% above and 20% below the original one. The subjects walked for 10 minutes at each of the speeds and, in the last three minutes, the VO2, HR, and BP were assessed. In order to compare variables between groups the variance was performed (ANOVA) followed by the Post Hoc Sheffé test (p < 0.05). Results The amputees selected lower values of PWS and had higher HR, BP, and EC, VO2 during gait when compared to normal individuals. The transfemoral amputees had higher VO2 and EC compared to the transtibial ones. By analyzing the speed effect, it was observed that, although the VO2 did not increase with the increased speed, there was increased cardiovascular response and reduced EC. Conclusions Traumatic lower limb amputees have higher energy expenditure and cardiovascular responses during gait and, at higher speeds, they become more economical, reducing the EC.

Rate Of Improvement

Virtual reality (VR)-based rehabilitation has been used in lower limb amputees; however, the extent to which VR is effective in reacquiring symmetrical gait in lower limb amputees is unclear. The purpose of this study was to confirm whether a VR intervention is effective in obtaining a simulated prosthetic gait. The participants were 24 healthy males who had never worn a simulated prosthesis. They were divided into three groups: VR, tablet, and control groups. The intervention consisted of 5 min of in situ stepping on parallel bars and watching a video of a simulated prosthetic leg walker on a head-mounted display or a tablet. Measurements included Gait Up parameters during a 10-m walk and immersion scores. After the intervention, there was a significant interaction between walking speed and leg swing speed in the VR group. The rate of improvement in walking speed and immersion scores was significantly higher in the VR group than in the other two groups, and there was a significant positive correlation between the rate of improvement and immersion scores. Compared to the tablet and control groups, the VR group showed the highest rate of immersion and improvement in walking speed.

Foot Disorder

Flat foot is the most common foot disorder that influences the alignment of the lower limb structure. It is controversial whether the use of foot insole influences kinetic and kinematic of the leg or not. Therefore, this study investigated the influence of foot insole on the gait performance in subjects with flat foot disorder. A group of flat foot subject was recruited into this study (the number of subjects was 15). The motion of the leg joints was determined using the Qualysis motion analysis system. Moreover, the force applied on the lower limb was recorded by a Kistler force plate. The range of motion of the lower limb joints, the moments applied on the lower limb joints and force transmitted through the leg were the parameters used in this study. The difference between these parameters during walking with and without insole was evaluated using the paired [Formula: see text]-test. Significant value was set at [Formula: see text]. There was no significant difference between the range of motion of ankle joint while walking with and without insole. However, the medial directed force applied on the leg decreased significantly [Formula: see text]. The use of foot insole did not influence the moments transmitted through the hip and knee joints. The walking speed of the subjects improved while walking with foot insole. Use of foot insole influenced the magnitude of the force applied on the leg and the adductor moment of ankle joint due to its influence on foot alignment. As the walking speed of the improved subjects follows the use of insole, it can be concluded that it may have a positive effects on the performance of flat foot subjects.
