During walking elders increase efforts at proximal joints and keep low kinetics at the ankle

Background: Both ageing and speed definitely affect gait patterns. Since most of the comparisons between young and elderly people while walking have been carried out at different "self-selected" speeds, results might be biased by a lack of control of the e ...

Dopaminergic influences on formation of a motor memory

Friedhelm Christoph Hummel

The ability of the central nervous system to form motor memories, a process contributing to motor learning and skill acquisition, decreases with age. Dopaminergic activity, one of the mechanisms implicated in memory formation, experiences a similar decline ...

Dual-task-related gait changes in the elderly: Does the type of cognitive task matter?

Kamiar Aminian

Dual-task-related gait changes among older adults while they perform spoken verbal tasks have been reported frequently. The authors examined whether the type of walking-associated spoken verbal task matters for dual-task-related gait changes in 16 older ad ...

Ambulatory system for human motion analysis using a kinematic sensor: Monitoring of daily physical activity in the elderly

Kamiar Aminian, Philippe Robert, Anisoara Ionescu, Bijan Najafi

A new method of physical activity monitoring is presented, which is able to detect body postures (sitting, standing, and lying) and periods of walking in elderly persons using only one kinematic sensor attached to the chest. The wavelet transform, in conju ...

Elevated heels and adaptation to new shoes in frail elderly women

Kamiar Aminian, Bijan Najafi

Footwear is supposed to have influence on postural control and is a potential aspect to address in the prevention of falls in the elderly. This study aimed to show whether measurements of static balance and gait are different with habitual shoes compared t ...

Is Dual task testing more sensitive to detect gait improvement after a balance training program?

Kamiar Aminian, Bijan Najafi

There is a growing interest in the role played by attention and cognitive processing in the control of posture and gait, investigated by means of dual task methodology. The rationale for dual task testing is to assess whether the simultaneous performance o ...

Measurement of stand-sit and sit-stand transitions using a miniature gyroscope and its application in fall risk evaluation in the elderly

Kamiar Aminian, Philippe Robert, Bijan Najafi

A new method of evaluating the characteristics of postural transition (PT) and their correlation with falling risk in elderly people is described. The time of sit-to-stand and stand-to-sit transitions and their duration were measured using a miniature gyro ...

ESMAC-SIAMOC 2001 Joint Congress: Body Postures and Walking Period Estimation Using a Kinematic Sensor: Application for Long Term Monitoring of Physical Activity in Elderly Subjects

Kamiar Aminian, Philippe Robert, Anisoara Ionescu, Bijan Najafi

Introduction: A reliable measurement of the physical activity in everyday life should allow a better assessment of the utility and the relevance of a number of medical treatments. Continuous 24-h recordings of posture and motion can be generally useful in ...

Falling risk evaluation in elderly using miniature gyroscope

Kamiar Aminian, Philippe Robert, Bijan Najafi

The time of sit-stand and stand-sit transition and its duration were measured using a miniature gyroscope on the chest and a portable recorder on the waist Based on a simple model and wavelet analysis, three parameters related to postural transition, namel ...
