Direct measurement of ankle stiffness during quiet standing: implications for control modelling and clinical application

Center of pressure excursion as a measure of balance performance in patients with non-specific low back pain compared to healthy controls: a systematic review of the literature

“…Visual obstruction will therefore exhibit a profound effect on balance as the system is deprived of two major contributors for postural control. The pronounced anteroposterior sway with the resulting raised ankle stiffness [11] observed in NSLBP sufferers [23,26,29] may be seen as a compensatory mechanism to enhance sensory discrimination and thereby compensate for the deterioration of the feedback loop [29].…”

“…Deterioration of this proprioceptive information from these areas may be the determining factor in reducing the accuracy in the sensory integration process. The resulting imprecise estimation of the COM position especially in chronic LBP sufferers may then lead to an increase in the safety margin of the adaptive COP shifts with regard to the predicted COM oscillations [11].…”

Revisão sobre posturografia baseada em plataforma de força para avaliação do equilíbrio

“…Such passive stiffness acts similar to an "elastic" opposed to the torque of gravitational force, which has the tendency to cause a forward fall of the body. Although the estimative of the contribution of the restoring torque due to the passive stiffness varies widely in the literature, it is estimated that this torque ranges about 65% to 90% from the magnitude of the gravitational torque 7,8 . Therefore, more than half of the torque responsible for maintaining our erect posture would be generated by a purely passive component, independent of the direct participation of the nervous system.…”

Quantitative Gait Analysis of Healthy Adults Using Foot Print Method and Win Track

“…Although this type of analysis system is installed in many laboratories but it is expensive and limited to research zone only. [18][19]There is one another option available for gait analysis which uses wearable sensors in the shoes or waist of the patient, it is inexpensive and a popular mode of gait analysis.These sensors may be accelerometers, gyrosensors, force sensors, strain gauges, inclinometers, goniometers and soon. [20][21] Human locomotion is a periodic activity of the body segments which involve the repetitive motions.…”
