FallScreen© is a falls risk calculator and has two forms: a short form and a long form. The short form is designed as a screening instrument suitable for General Practice surgeries, acute hospitals, and long-term care institutions. It takes only 15 minutes to administer and contains five items: a single assessment of vision, peripheral sensation, lower limb strength, reaction time and body sway. FallScreen©是跌倒风险计算器并有两种形式:一个短时间和长时间。短时间的形式被设计成适用于全科手术,急诊医院和长期护理机构的筛选工具。这需要管理只需15分钟,包含五个项目:视力,外周感觉,下肢力量,反应时间和身体摇摆的一个评估。
The long form is designed as a comprehensive instrument suitable for Rehabilitation and Physical Therapy and Occupational Therapy settings and for dedicated Falls Clinics. It takes 45 minutes to administer and contains 15 items: three assessments of vision (high and low contrast visual acuity and edge contrast sensitivity), three assessments of peripheral sensation (tactile sensitivity, vibration sense and proprioception), assessments of three lower limb muscle groups (knee extensors, knee flexors and ankle dorsiflexors), assessments of both hand and foot reaction time and four assessments of body sway (sway on floor and foam with eyes open and closed).
Prof Stephen Lord's Physiological Profile Assessment (PPA) has been marketed through Neuroscience Research Australia (formerly the Prince of Wales Medical Research Institute) as POWMRI FallScreen®. These tools are now used in over 150 research and clinical settings within Australia and across the world, Belgium, Canada, China, Denmark, Finland, Korea, Malta, New Zealand, Norway, Poland, Singapore, Sweden, Switzerland, Taiwan, USA and UK.
The physiological assessmentsVisual function is measured using a dual contrast visual acuity chart, the "Melbourne Edge Test" and a device for measuring depth perception. Lower limb sensation is assessed with tests of proprioception, touch sensitivity and vibration sense. The strength of three muscle groups in both legs is measured: the knee flexors and extensors and ankle dorsiflexors. Simple reaction time is assessed using movement of the finger as the response, and choice reaction time is assessed using a step as the response. Body sway on a firm and compliant (foam rubber) surface with eyes open is assessed using a swaymeter that measures displacements of the body at the level of the waist.
These assessments are simple, 'low-tech' and readily accepted by older subjects. All have high external validity and test-retest reliability and are described in detail in our published papers (1-7). When combined in multivariate discriminant analyses, we have found that these tests can predict those at risk of falling with 75% accuracy in both community and institutional settings.
