“…Traballesi et al postulated that the treadmill test overestimates the energy consumption. 7 We preferred the treadmill because of its advantages like the ability to use a standard protocol and having options of different speed and slope combinations. Besides, it was shown that field test Energy expenditure of amputeesresults can vary depending on the terrain.…”

Amputee patients spend more energy during walking than able-bodied persons. It is generally accepted that more proximal amputation is associated with more energy need. However, the picture is not clear, especially for partial foot amputees. The purpose of this study was to compare the energy consumption of walking in traumatic unilateral amputees with three different amputation levels (transfemoral, trans-tibial and partial foot amputations). Sixty-four male unilateral traumatic amputees participated in this study. Energy expenditure during walking was measured for four different speed and slope combinations: 1.5 km/h and 08 slope, 3 km/h and 08 slope, 1.5 km/h and 58 slope, 3 km/h and 58 slope. Mean O 2 consumption (ml/kg/min) of the last 2 min of each 5-min session was calculated. In all four combinations, energy expenditure of trans-tibial amputees was the lowest, and energy expenditure of trans-femoral amputees was the highest. Statistical significance, however, could not be obtained for the differences among the groups. In conclusion, walking of partial foot amputees does not seem to be more energy efficient than that of higher level amputees.

“…Other influencing factors include walking surface [6,8,[15][16], prosthetic componentry [17][18][19][20][21], prosthesis gait experience [22], residual limb length [1,10], baseline fitness [1,6,23], age [1,6], and comorbidities [9,23]. Gaily et al considered multiple factors of energy expenditure following TTA and found that the baseline rate of oxygen consumption (VO 2 ) contributed to 40 percent of the variance in the data [1].…”

Does unilateral transtibial amputation lead to greater metabolic demand during walking?

et al. 2014

Abstract-Previous literature reports greater metabolic demand of walking following transtibial amputation. However, most research focuses on relatively older, less active, and often dysvascular amputees. Servicemembers with traumatic amputation are typically young, fit, and highly active before and often following surgical amputation of their lower limb. This study compared the metabolic demand of walking in young, active individuals with traumatic unilateral transtibial amputation (TTA) and nondisabled controls. Heart rate (HR), rate of oxygen consumption, and rating of perceived exertion (RPE) were calculated as subjects walked at a self-selected velocity and at five standardized velocities based on leg length. The TTA group completed a Prosthetics Evaluation Questionnaire. Oxygen consumption (p = 0.89), net oxygen consumption (p = 0.32), and RPE (p = 0.14) did not differ between groups. Compared with controls, HR was greater in the TTA group and increased to a greater extent with velocity (p < 0.001). Overall, the TTA group rated their walking abilities as high (mean: 93% out of 100%). This is the first study to report equivalent metabolic demand between persons with amputation and controls walking at the same velocity. These results may reflect the physical fitness of the young servicemembers with traumatic amputations and may serve to guide outcome expectations in the future.

ÖZAmaç: Bu çalışmada, kol salınımı kısıtlanmasının tercih edilen yürüme hızı, yürüme sırasında harcanan oksijen miktarı ve vücut kütle merkezi dikey yer değişimi üzerine etkileri araştırıldı. Gereç ve yöntemler:Çalışmaya Şubat 2011 -Nisan 2011 tarihleri arasında yaşları 18-30 yıl arasında değişen 52 sağlıklı erkek gönüllü katıldı ve beş farklı yürüme modeli kullanıldı. Her yürüme modeli için bireylerin zeminde tercih edilen yürüme hızları belirlendi. Bireyler bu hız ile koşu bandında yedi dakika yürütülerek oksijen tüketimleri kaydedildi. Birinci sakral vertebraya işaretleyici yerleştirildi ve iki kızıl ötesi kamera ile yürüme sırasında vücut kütle merkezi dikey yer değişimini belirlemek için kayıt yapıldı. Sonuç: Kol salınımının dengeyi sağlamada yardımcı olduğu, ancak, her iki kol salınımının kısıtlandığı durumlarda biyomekanik sistemlerin bu değişikliği kompanse edemediği için vücut kütle merkezi dikey yer değişimini ve yürümenin oksijen maliyetini artırdığı kanısındayız. Denge sorunu yaşayan bireylerde günlük kazaların önlemesi konusunda bulgularımızın yardımcı olabileceğini düşünmekteyiz.Anahtar sözcükler: Denge; yürüme; oksijen tüketimi; hız; üst ekstremite. ABSTRACTObjectives: This study aims to investigate the effects of arm swing restrain on preferred walking speed, amount of oxygen spent during walking and vertical displacement of the center of mass. Materials and methods:Between February 2011 and April 2011, a total of 52 healthy male volunteers, in the age range of 18 to 30, participated in the study and five different walking models were used. Individuals' preferred walking speeds on the ground were determined for each model. Their oxygen expenditures were recorded while individuals walked on the treadmill at this speed for seven minutes. We placed a marker on the first sacral vertebrae and used two infrared cameras to determine the changes in vertical displacement of the center of mass during walking. Results:We found a significant difference (F(3.734, 204) = 5.606, p<0.05) between normal (0.158±0.021 mL/kg/m) and at side restraint (0.166±022 mL/kg/m) and at front restraint (0.166±023 mL/kg/m) models in oxygen cost. We also found a significant difference (F(3.461, 204) = 5.144, p<0.05) between normal (3.81±0.94 cm) and at side restraint (4.36±1.05 cm) and at front restraint (4.25±0.93 cm) models in terms of vertical displacement of the center of mass. Preferred walking speed in the normal model (5.06±0.62 km/hr) was significantly higher (F(3.387, 204) = 10.433, p<0.05) than other models (at right restraint; 4.93±0.65 km/hr, at left restraint; 4.92±0.62 km/hr, at side restraint; 4.88±0.61 km/hr, and at front restraint; 4.88±0.56 km/hr). Conclusion:We are of the opinion that arm swing helps providing balance but in the situation of both arm restrain, since biomechanical systems cannot compensate this modification,...
