BIOMECHANICAL CHARACTERISTICS DURING INITIATION OF GAIT

Kang Hee Cho, Bong-Ok Kim (Chungnam National University, Taejon, Korea)

 

The purpose of this study was to understand biomechanical characteristics during the process of initiation of gait (IOG) from standing, time spent from start signal to heel strike of the stance limb.

During initiation of gait period of swing and stance limbs, kinematic and kinetic evaluation were performed with ELITE CCD camera, force platform and dynamic eletromyography in 20 healthy men.

The results were as follows:

1) The latency of IOG of swing limb was 73 msec and total IOG period of swing limb was 1376 msec.

2) The period of I OG were divided into 5 phases, prerelease phase (0-18.5%), unloading phase (18.5- 35.0%), loading phase (35.0- 58.5%), double support phase (58.5-70.9%) and swing phase (70.9-100%).

3) Initial movement of center of pressure to swing limb and posterior direction was caused by asymmetric activity of anterior tibialis and quadriceps of both limb, and activity of gluteus medius of the stance limb.

This pattern of IOG can be used as a part of control database when initiation of gait is to be studied in subjects with neuromusculoskeletal abnormalities.

CERVICAL FEMORAL ANTEVERSION (CFA) - ITS PHYSIOLOGIC ROLE

Madan M. Telikicherla (Rehabilitation Institute of Michigan, Detroit - USA)

 

Purpose: To enhance our understanding of human gait

Method: Hypothesis The Orthopedic literature is replete with the description, mechanogenesis and clinical applications of CFA. There is however, a striking absence of any reference to its physiologic role. We postulate that the CFA contributes to conservation of energy during i) static standing and ii) walking through, separate biomechanical mechanisms. During static standing, CFA creates extension moments at the hip and the knee, through harnessing the global gravitational force and sparing the energy of gluteus maximus and quadriceps muscles. During walking, in association with the neck-shaft angle of the femur, CFA reduces the effective coronal distance between the proximal shaft of the femur and the fulcrum of the hip, resulting in decrease in the side to side excursion of body's center of mass, thus conserving the energy. These two hypotheses explain the biomechanical basis of CFA..

Result: Needs experimental study to determine the validity of this hypothesis. Conclusion: The spatial configuration of femoral neck could be the seventh determinant of gait.
