The purpose of this study was to compare gait deviations between Kondylen Bettung
Munster (KBM) and vacuum prosthetic fitting using the Gait Profile Score (GPS),
the Movement Analysis Profile (MAP) and temporal-spatial parameters. Seventeen
transtibial amputees that received their prosthesis from the Brazilian
governmental health system participated in this study. Twelve of them used KBM
prosthetic fitting on their prosthesis and five used vacuum prosthetic fitting.
Kinematic and temporal-spatial parameters data were captured by a six-camera
Motion Analysis system (Santa Rosa, CA). The results showed that the vacuum group
walked faster than the KBM group but the differences in temporal-spatial
parameters between them were not significant. The GPS for the intact limb (IL)
and the overall GPS differentiated between the groups of prosthetic fitting. Hip
flexion/extension and knee flexion/extension were higher in KBM group than in the
vacuum group, although only knee flexion/extension for the intact limb revealed
significant difference between the groups. In KBM group, the major deviations
were in hip flexion/extension for both limbs, knee flexion/extension for both
limbs and ankle dorsi/plantar flexion for the prosthetic limb. The vacuum group
showed deviations especially in ankle dorsi/plantar flexion for both limbs, knee
flexion/extension for the prosthetic limb and hip rotation for the prosthetic
limb. Besides, the vacuum group was more symmetrical than the KBM group. This
study concluded that subjects who used vacuum prosthetic fitting presented
smaller gait deviations and a more symmetrical gait than those who used KBM
prosthetic fitting.
