Abstract

Background

Older adults with knee osteoarthritis are twice as likely to fall compared to healthy counterparts. Furthermore, in healthy older adults, greater trunk flexion is associated with increased falling. While spatio-temporal and strength measures have been connected to balance dysfunction in osteoarthritis, to date no studies have investigated compensation of both upper and lower body kinematics on balance recovery in this population.

Methods

Forty-eight older people with knee osteoarthritis (age 71.02 ± 6.76 years, 54 % females, BMI 29.10 ± 4.58) and 15 asymptomatic controls (age 72.47 ± 4.81, 27 % females, BMI 26.17 ± 3.06) completed balance recovery during a simulated forwards fall. Ankle, knee, hip, trunk and head kinematics were collected and analysed using three trial types (no additional, cognitive dual-task and physical dual-task). Two-way MANCOVA were conducted to identify group differences in ankle, knee, hip, and trunk angle, and head position (control and knee osteoarthritis), trial differences (no additional, cognitive and physical dual-task) and group by trial differences.

Findings

Postural differences in older adults with knee osteoarthritis included greater knee flexion (p = .02) and lower hip and trunk flexion (p < .01).

Interpretation

Following a simulated fall, older adults with knee osteoarthritis showed greater knee flexion at first contact which might suggest inability to resist forwards motion of the body.The more extended hip in this group and the resulting compensation of the upper body posture may lead to no difference in number of steps taken when compared to controls.

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
