  • Effects of pelvic movement on center of gravity movement and mechanical efficiency during walking

    Assistance  

    Project Year:2015.04 - 2018.03 

    Investigator(s): Kanzaki Hideto  ,  Member: MAKABE HITOSHI, TAKAHASHI TOSHIAKI, MINAMISAWA TADAYOSHI, AKATUKA SEIYA, NAGASE TOKIKO, IHASHI KOUJI

    We examined the effects of pelvic movement limitation on the mechanical efficiency of walking, the kinematic parameters of the lower limbs and trunk, and lower limb muscle activity. We asked healthy young adults to walk on a walking path under these conditions that artificially induced leg length discrepancy, restricted movement of the trunk, hip, or knee joint. The kinematic and kinetic parameters of walking were compared with those obtained without restriction. For comfortable speed walking, healthy young people showed that various compensatory movements worked on lower limb joints under any condition. The mechanical efficiency of movement of the center of gravity during walking was preserved. Results of this study are expected to be useful as control data for evaluating the walking of patients who have restricted or asymmetric movement of the pelvis caused by aging and various impediments.

  • Evaluation of gait dynamics by nonlinear analysis and its clinical application

    Assistance  

    Project Year:2014.04 - 2017.03 

    Investigator(s): Makabe Hitoshi  ,  Member: Kanzaki Hideto, Minamisawa Tadayoshi

    This study was aimed at analyzing stride interval (SI) variability during gait by using nonlinear analysis and examining its clinical usefulness. The scaling exponent (α) and approximate entropy (ApEn) were determined as evaluation parameters in the nonlinear analysis. α showed long-range correlation in SI variability, while ApEn presented regularity in SI variability. The results of this study showed a significant difference in α and ApEn by walking stick use and leg-length difference. Significant differences were observed in α and ApEn, depending on age, and the difference became remarkable, especially by loading a cognitive task. Those may be caused by deterioration of brain network function during gait due to aging. Hence, α and ApEn may be useful indicators of deterioration of brain network function.

  • Kinetic analysis of rocker functions of the foot

    Assistance  

    Project Year:2012.04 - 2015.03 

    Investigator(s): KANZAKI Hideto  ,  Member: IHASHI Kouji, MAKABE Hitoshi, TAKAHASHI Toshiaki, MINAMISAWA Tadayoshi, AKATUKA Seiya, NAGASE Tokiko

    By limiting the biomechanical roles of three rocker functions produced at the foot region in the stance phase while walking, we examined those functions. Results show that limited rocker functions change the center of mass (COM) displacement pattern, lower leg joint movement, joint moments, shock absorber, and foot stress distribution, as well as decrease the walking velocity. However, limited rocker functions maintained the rate of exchange between kinetic energy and potential energy, which represents smooth displacement of the COM. Results suggest that limiting rocker functions restricts forward displacement of the COM, but walking mechanical efficiency, at least in a young and healthy person, can be maintained by some compensatory movements.

  • How to carry heavy loads to protect the lower limb joints.

    Assistance  

    Project Year:2009.04 - 2012.03 

    Investigator(s): KANZAKI Hideto  ,  Member: IHASHI Kouji, MAKABE Hitoshi, TAKAHASHI Toshiaki, MINAMISAWA Tadayoshi, AKATUKA Seiya, NAGASE Tokiko, MIWA Makoto, SUZUKI Shinya, SASAKI Kazuhiro

    The purpose of this study is to examine the effects of carrying position on the kinetic parameters and muscle activities of the spine and lower limb during walking. The four carrying positions were "holding a bag on his back," "holding a bag anterior to the chest with both hands," "holding a bag in their right hand" and "holding a bag on their right shoulder". It was suggested that when the bag was held in the hand, an excessive load might be added to the spine and the hip joint of the opposite side and the knee joint of the same side. When the bag is held anterior to the chest with both hands, an excessive load might be added on the spine and hip joints of both sides.
