“…Older people seem to walk with smaller step lengths compared to young adults (Kavanagh et al 2004;Menz et al 2003;Oberg et al 1993). A gait pattern with reduced step length has speciWcally been observed in older people with Parkinson's disease (Morris et al 1994;Zijlstra et al 1998), older patients with osteo-arthritis (van den AkkerScheek et al 2007;Hulet et al 2000;McGibbon and Krebs 2002) and in older people with fall incidents (Richardson et al 2005), or fear of falling (Aizen 2001;Nutt 2001).…”

This study evaluated the step length-frequency relationship in physically active community-dwelling older women in order to investigate whether the relationship between these two spatio-temporal gait parameters changes with increasing age. Forty older women in four age groups, i.e. 64-69, 70-74, 75-79 and 80-85 year olds, participated in the study. Subjects walked at Wve diVerent self-selected speeds and while simultaneously performing an additional cognitive and/or upper-extremity motor task. Gait parameters were determined from forward accelerations measured by a tri-axial accelerometer on the lower back. All subjects demonstrated a strong linear relationship between step length and step frequency for walking at diVerent speeds. No evidence for a change in the step length-frequency relationship with age was found, suggesting that there are no diVerences between physically active older women of diVerent age groups regarding the adoption of a "cautious gait", i.e. a gait pattern characterized by a reduced step length.

“…노인의 경우 낙상사고의 70%가 보행 중 발 생한다고 알려져 있으며 [1,2], 많은 연구에서 고령자의 보행 패 턴에서 스텝 길이 (step length)와 분당 걸음 수 (cadence)가 감 소하고 입각기 시간 (stance time)이 길어진다고 보고되었다 [3][4][5]. 과거의 보행에 대한 연구는 주로 하체에 국한되어 있었으나, 최근에는 보행시 하체뿐 아니라 상체도 보행의 안정성 유지에 대 해 중요한 역할을 하는 것으로 알려졌다 [6][7][8].

-The purpose of this study was to investigate possible age differences in the attenuation of acceleration in the upper body (from pelvis through shoulder to head) during fast walking. Thirty young and 29 elderly subjects participated in this study. Wireless acceleration sensors were attached on head, shoulder, and pelvis. Subjects performed two trials of fast walking on a treadmill, where the fast speed was defined as 1.5 times of the comfortable speed. Root-mean-squared (RMS) accelerations of each axis were compared with age group and sensor position as independent factors. In the AP direction, the pelvis acceleration was greater in the young and the shoulder-to-head attenuation was also greater in the young (p<0.001), so that the head acceleration was comparable between age groups (p=0.581). In the ML direction, the pelvis acceleration was greater in the young and also the pelvis-to-shoulder attenuation was greater in the young (p<0.001), so that the head acceleration was greater in the elderly group (p<0.001). Insufficient attenuation ML acceleration in the elderly resulting in the greater acceleration in the head may deteriorate the balance control which utilize feedback signals from the sensory organs in head, e.g., vestibular and visual systems.

“…This method has advantages such as simple measurement, low cost, and no restriction on location compared with gait analysis using force plates and a 3-dimensional motion analysis system. Several studies have reported the use of an accelerometer for gait analysis [1][2][3][4][5][6][7][8][9][10][11][12][13] . In those studies, a gait index was calculated from the trunk acceleration, and gait analysis was conducted based on it.…”

“…AC has been reported to be useful in the evaluation of the risk of fall for elderly people, as a measure of the regularity and symmetry of gait [11][12][13] . A tri-axial accelerometer is commonly used in gait analysis to measure acceleration in the vertical (VT), anteroposterior (AP) and mediolateral (ML) directions of the body 2,[4][5][6][7][8][9][11][12][13] . However, few reports that compared the characteristics of these three directions, and there are few reports on the differences of RMS and AC among the VT, AP, and ML directions.…”

Abstract.[Purpose] The purpose of this study was to investigate the validity of an evaluation index of the vertical (VT), anteroposterior (AP), and mediolateral (ML) directions of trunk acceleration during walking.[Methods] Twenty-nine subjects volunteered for this study. Trunk acceleration and ground reaction force (GRF) during normal walking were measured. The root mean square (RMS), stride regularity (SR), and step symmetry (SS) were calculated on the basis of trunk acceleration. The displacement of COG was calculated by the double integration of GRF. The components of RMS, SS, SR, and COG were calculated in the AP, VT, and ML directions. We analyzed the correlation between RMS and COG and assessed differences among the three directions in SR and SS. [Results] We observed a significant correlation between RMS and COG in VT. SS and SR in the VT and AP directions were significantly higher than those in the ML direction.[Conclusion] These results suggest that RMS in the VT direction is useful in the gait analysis, SS and SR in the AP and VT directions were useful as indices showing the degree of deviation from normal gait.
