Professor Stephen Lord is a Senior Principal Research Fellow at Neuroscience Research Australia, Sydney, Australia. He has published over 400 papers in the areas of balance, gait and falls in older people and is acknowledged as a leading international researcher in his field. His research follows two main themes: the identification of physiological risk factors for falls and the development and evaluation of fall prevention strategies. Key aspects of this research have been the elucidation of sensorimotor factors that underpin balance and gait and the design and evaluation of exercise programs for older people including those at increased risk of falls, i.e. people with Parkinson’s disease, stroke, dementia and frailty. His methodology and approach to fall-risk assessment has been adopted by many researchers and clinicians across the world and he is actively engaged in initiatives aimed at implementing falls prevention evidence into policy and practice.
In December 2019, Stephen was awarded the Lifetime Achievement Award by the President of the British Geriatrics Society in recognition for his contribution to falls research.
The ReacStep study is investigating the short-term effects of two balance training programs (i.e. reactive balance training and conventional balance training) on balance recovery from slips and trips in older adults. These programs are designed from evidence-based research and offer a challenging and unique experience to improving balance.
The ReacStep team are calling on volunteers who:
Eligible volunteers will be subjected to a health and safety screening before they are enrolled and randomly allocated into one of the two groups. Both groups will undertake a 3-week training program with an exercise physiologist, at NeuRA (i.e. in Randwick) as well as a balance recovery assessment at the 4-week time point.
Reactive balance training involves intentionally stepping on a sliding tile, stepping over obstacles, trigger-release recovery as well as strength training. Participants will be wearing a full-body safety harness to ensure safety.
Conventional balance training involves keeping balance in varying foot positions (i.e. feet together, in tandem or on one leg) whilst performing secondary tasks such as throwing a ball, card sorting, solving a maze or playing computer games.

Walking is not automatic and requires attention and brain processing to maintain balance and prevent falling over. Brain structure and function deteriorate with ageing and neurodegenerative disorders, in turn impacting both cognitive and motor functions.
This series of studies will investigate:
The experiments involve experimental paradigms that challenge cognitive functions of interest (eg.visuo-spatial working memory, inhibitory function). I use functional near-infrared spectroscopy to study activation in superficial cortical regions of interest (eg. prefrontal cortex, supplementary motor area…). The studies involve young and older people as well as clinical groups (eg.Parkinson’s disease).
This research will greatly improve our understanding of the interactions between brain capacity, functions and balance control across ageing and diseases, psychological, physiological and medical factors, allows to identify targets for rehabilitation.
It will also help identifying whether exercise-based interventions improve neural efficiency for enhanced balance control.
Research investigating the impacts of cognitive behavioural therapy and balance programs on fear of falling, funded by Mindgardens.
Falls and fear of falling affect many older people and can impose limitations upon daily activities. Over one third of community dwelling older people fall each year with about 15% of falls being injurious. However, two thirds of older people express a fear of falling during common daily activities, making it more common than falls itself. Fear of falling has been associated with needless restriction in physical and social activities, and subsequent deterioration of health and wellbeing.
Previous research has suggested that fear of falling can be reduced through cognitive behavioural therapy (CBT) and balance exercise programs. However, these face-to-face treatments are resource intensive and not readily accessible to people. Furthermore, the effects of these treatments on fear of falling are small and often do not last beyond the duration of the program.
By utilising technology and providing tailored physical activity guidance we are aiming to reduce a fear of falling in an accessible, efficient and lasting way.
A thee-arm randomised clinical trial will be conducted in 189 community-dwelling older adults with a substantial concern of falling. Participants will be randomly allocated into one of three groups in order to test whether a self-managed CBT intervention, alone or in combination with a graded balance activity program, can reduce concerns about falling in older adults when compared to usual care.
We are collaborating with the Black Dog institute to provide a home-based cognitive behavioural therapy program that addresses a fear of falling. We will also be utilising our cutting-edge balance program StandingTall to provide a graded balance program.
The SafeTrip study will to investigate how older adults learn protective stepping skills to avoid falls when encountering obstacles, trips and slips. With NeuRA’s cutting-edge motion capture system and other wearable devices, the SafeTrip team will be able to observe and analyse movement and muscle activity during reactive or proactive step training.
The SafeTrip team are looking for older volunteers aged 65 years and over who:
Eligible volunteers will be invited to NeuRA for some baseline assessments before being randomly allocated to either the intervention or control group. Only the intervention group will undertake 3 weekly reactive balance training sessions followed by 3-monthly retraining sessions, while the control group assume their usual activity. All participants will receive a fall prevention information booklet and will be invited back to NeuRA for a 12-month re-assessment.

There is emerging evidence that visuo-spatial processing is involved in balance control during gait. Importantly, visuo-spatial processing may be key for fall avoidance as it enables one to precisely remember the position and physical characteristics of upcoming hazards; an essential skill for the safe navigation of everyday environments. Yet, investigations of visuospatial processing use for obstacle avoidance have been restricted to animal studies and young adults. No studies have been undertaken in older people or people with Parkinson’s Disease for whom visuo-spatial processing deficits are evident and associated with impaired postural control.
This series of studies will investigate visuo-spatial processing required for obstacle avoidance and navigation in older people, older people at high risk of falls and people with Parkinson’s Disease. We will use motion capture to investigate behavioural outcomes and a freely-worn brain imaging device, functional near-infrared spectroscopy to study cortical activation in regions of interest. We will conduct two experiments one involving an obstacle crossing task and another, a stepping task.
We hypothesize that older age, Parkinson’s Disease and increasing task complexity will result in increased risk of tripping and impaired visuo-motor performance, in the obstacle crossing task and in the stepping task, respectively.
This research will greatly improve our understanding of central mechanisms for fall risk and build on our recent behavioural work in this area.

Gait dysfunction in Mulitple Sclerosis is an important risk factor for falls. Although there is detailed biomechanical evidence of impaired gait patterns in people with Multiple Sclerosis, there is a paucity of objective empirical data relating specific lower limb muscle strength deficits and gait impairments. Most studies to date have used manual muscle testing to investigate lower limb muscle strength and/or have only focused on knee flexors and extensors.
In this study, we aim to identify weak lower limb muscles contributing to gait impairment in Multiple Sclerosis.
Our experimental protocol involves a comprehensive assessment of isometric strength in eight major lower limb muscle groups using electronic strain gauges. We then conduct a full lower-limb gait analysis using motion capture and force platforms. We will conduct statistical analyses to determine which weak muscle groups are significantly associated with markers of gait impairment in Multiple Sclerosis (eg. knee range of motion during the gait cycle). We are also planning to use electromyography on the identified deficient muscle groups in a subset of participants.
Our research will identify the muscle groups contributing to poor gait, likely causing imbalance and trips in people with Multiple Sclerosis. This work is crucial for developing progressive resistance training programs that directly target weak muscle groups to improve gait in people with Multiple Sclerosis.
A randomised controlled trial to reduce the risk of falling in people with Parkinson’s disease.
An engaging self-managed neuro-rehabilitation program using eHealth technologies to improve mobility and enhance independence in people with Parkinson’s disease:
Parkinson’s disease is a multi-systems neurodegenerative disease with the severity of clinical symptoms (including postural instability, gait dysfunction an falls). With the population aging, the number of people affected by Parkinson’s disease is expected to double every 25 years presenting an increasing burden on health service and society as a whole. Falls are a common and devastating event in individuals with Parkinson’s disease and often precipitated by excessive gait variability, postural instability and freezing of gait.
Visual, attentional, haptic and auditory stimuli have been used to improve gait dysfunction in people with Parkinson’s disease. The aim of this project is to develop and evaluate a self-managed program using mHealth technology to improve mobility in people suffering from Parkinson’s disease. Dr Matthew Brodie was awarded a Michael & Elizabeth Gilbert Scholarship in Parkinson’s Disease Research.
An international alliance lays the groundwork for the widespread implementation of StandingTall. This study targets a major need for older people for whom falls are a real risk that can have debilitating impacts on quality of life. It has been developed with major input from all partners and constitutes a valuable, collaborative partnership between researchers, experts in health promotion, health care providers and policy makers. Our partners for this project are the NSW Office of Preventive Health, Ministry of Health; the Clinical Excellence Commission; and the Agency for Clinical Innovation; two NSW Local Health Districts; i.e. Northern NSW and mid-North Coast; Austin Health, Uniting and the Northern Health Science Alliance in the United Kingdom. PLEASE NOTE: recruitment has finished for Australia.
The study aims to accelerate the implementation of StandingTall. It will address the final steps needed to scale up this innovative technology for widespread use by older people across Australia and England with prospects for further international translation. The overall aim of this international project is to establish integrated processes and pathways to deliver StandingTall to older people and to provide ongoing support as required. The project provides scope for further broad scale implementation and a model for incorporating StandingTall into existing health services and routine care.

Falls and functional decline are common in people with dementia. Falls are more likely to result in injury, death and institutionalisation when compared to older people without dementia. There is limited evidence that falls can be prevented in people with dementia. Strategies aimed at maintaining independence and preventing decline and falls are urgently needed. This research will a) further our understanding of fall risk and functional decline and b) explore novel fall and decline prevention programs, including the use of technology in older people with dementia.
Technological advances have enabled less expensive ways to quantify physical fall risk in the homes of older people.
We are exploring whether unobtrusive monitoring of activities of daily living or regular unsupervised directed routine assessments using new sensor-based technologies can predict falls in older adults more accurately.
We are developing and validating a range of mobile apps to assess fall risk factors in research settings and clinical practice; i.e. questionnaires (fear of falling, physical activity, etc), sensorimotor assessments (balance, vision, etc) and cognitive assessments (executive functioning, processing speed, etc.).
We are also working on Smart home IT support for frail elderly people who live alone.

Inaccurate reach judgement predicts future falls and is associated with poorer global cognitive performance and executive function, increased concern about falling, slower reaction time and poorer balance. Our results offer insight into the disparity between actual and perceived physical capabilities in people with CI, and how this impacts their risk of falling.
To explore the relationship between cognitive performance and falls in older people with mild to moderate cognitive impairment (CI) by investigating the mediational effects of medical, medication, neuropsychological, and physiological factors. Within this sample of older people with mild to moderate CI, poorer EF increased the risk of multiple falls. This relationship was mediated by reaction time and postural sway,suggesting cognitively impaired older people with poorer EF may benefit from fall prevention programs targeting these mediating factors.
This study identified several risk factors of falls in older people with cognitive impairment, a number of which are potentially modifiable. Future research involving targeted interventions addressing medication use, balance, mood, and functional performance may prove useful for fall prevention in this population.
