Three-dimensional motion analysis has been used since the beginning
of the 1980s to evaluate many aspects of physical function of transtibial
amputees. Despite its common use for clinical research, there is large
variability in methods of capturing three-dimensional data, description of these
methods, reporting of joint kinematics and interpretation of research findings.
The aim of the following review is to critically examine the specific
methodologies used by researchers when collecting three-dimensional kinematic
data on transtibial amputees and to provide an overview of the methods used.
Study design: Systematic review. Methods: A systematic review of the literature
between January 1984 and June 2009 was conducted. A total of 68 papers were
identified for review based on the following criteria : experimental research
design, collection of three-dimensional kinematic data of lower-extremity joints,
and inclusion of transtibial amputees as experimental subjects. Results: A number
of methodological shortcomings were identified in the papers reviewed.
Conclusions: The authors recommend that future studies more appropriately address
the product name and number of prosthetic components used; how the position of
reflective markers on the prosthesis is defined; presentation of data from both
sound and affected sides; and definition of the neutral position of the ankle
when reporting kinematic data. Where possible, the authors recommend use of a
control group. Clinical relevance This paper has identified numerous sources of
discrepancy and potential error in kinematic data collected on trans-tibial
amputees. Clinicians and researchers should make themselves aware of these issues
when collecting and interpreting gait data.
