Abstract

A distal-to-proximal redistribution of joint work and reduction in ankle kinetics may contribute to declines in gait performance with advancing age. Interventions to improve ankle function could help maintain gait performance in old adults. Inertial measurement units are practical and inexpensive and may be used to provide biofeedback of foot angular velocity to improve ankle propulsive function during gait.

Purpose

This study assessed if real-time biofeedback of foot plantarflexion angular velocity influenced ankle kinetics and hip-to-ankle work ratio in old adults.

Methods

Eight healthy old adults walked at their preferred speed (PS), maximal speed (MS), and MS with auditory feedback for a 5% increase in foot plantarflexion velocity (AUD). Kinematic and ground reaction force data were collected, and joint kinetics were calculated.

Results

Ankle positive work was larger during MS (p<0.001) and AUD (p<0.001) compared to PS, and 8% larger during AUD compared to MS (p=0.01). Hip-to-ankle work ratio was not different during MS (p=0.053) compared to PS but AUD reduced the ratio by 7% compared to MS (p=0.03) and by 19% compared to PS (p=0.02).

Conclusion

The findings suggest that biofeedback of foot plantarflexion velocity may be an effective strategy to acutely increase ankle positive work and reduce hip-to-ankle work ratio during treadmill walking in old adults.

听觉生物反馈足角速度对老年健康成人推进功能和步态性能的影响

随着年龄的增长，关节工作的远端到近端再分配和踝关节动力学的降低可能导致步态性能的下降。改善踝关节功能的干预措施有助于维持老年人的步态表现。惯性测量单元实用且价格低廉，可用于提供足部角速度的生物反馈，以改善步态中的踝关节推进功能。目的本研究评估足跖屈曲角速度的实时生物反馈是否影响老年人踝关节动力学和髋-踝关节功比。方法8名健康老年人以首选速度（PS）、最大速度（MS）和MS伴听觉反馈行走，增加5%的足跖屈曲速度（AUD）。收集了运动学和地面反作用力数据，并计算了关节动力学。结果MS （p < 0.01）和AUD （p < 0.001）期间膝关节正功均大于MS (p < 0.01)， AUD期间膝关节正功比MS大8% （p < 0.01）。与PS相比，MS期间髋关节与脚踝的工作比没有差异（p=0.053），但与MS相比，AUD使该比率降低了7% (p=0.03)，与PS相比降低了19% （p=0.02）。结论足底屈曲速度的生物反馈可能是老年人在跑步机上剧烈增加踝关节正功和降低髋踝关节功比的有效策略。

期刊介绍： Gait & Posture is a vehicle for the publication of up-to-date basic and clinical research on all aspects of locomotion and balance. The topics covered include: Techniques for the measurement of gait and posture, and the standardization of results presentation; Studies of normal and pathological gait; Treatment of gait and postural abnormalities; Biomechanical and theoretical approaches to gait and posture; Mathematical models of joint and muscle mechanics; Neurological and musculoskeletal function in gait and posture; The evolution of upright posture and bipedal locomotion; Adaptations of carrying loads, walking on uneven surfaces, climbing stairs etc; spinal biomechanics only if they are directly related to gait and/or posture and are of general interest to our readers; The effect of aging and development on gait and posture; Psychological and cultural aspects of gait; Patient education.
