A new software has been released to assist patients with the condition in learning to walk better and for longer. It was co-designed by people with Parkinson's disease.

The Walking Tall app was created by a group under the direction of UNSW Sydney biomedical engineer Dr. Matthew A. Brodie after a clinical trial supported by the Shake It Up Australia Foundation and the Michael J. Fox Foundation for Parkinson's Research.

The app's gait re-training feature, which now lets users choose their own training duration and tempo before delivering a rhythmic metronomic beat for three distinct walking speeds that is intended to inspire movement, was used as part of the trial.

The programme, which is available for free download from the iOS and Android app stores, also features practical advice like "walk tall," "hold your shoulders back," and "focus on big steps," as well as motivational audio commentary.

While most people take walking for granted, people with Parkinson's Disease (PD) may find it to be extremely difficult due to the partially functioning nerve cells deep in their brains that are in charge of planning and coordinating body movement.

Gait dysfunction

People with PD thus frequently experience gait impairment, a decline in coordination, and potentially significant step length issues.

Therefore, gait dysfunction can have a significant influence on independence and quality of life, and it causes falls in about 70% of people with Parkinson's disease.

Around 150,000 people only in Australia, out of an estimated 10 million worldwide, have PD.

Parkinson's disease is a significant issue in Australia, therefore the introduction of these new diagnostic methods and treatment options is encouraging, according to Vicki Miller, CEO of the Shake It Up Australia Foundation.

Direct feedback and recommendations from persons with PD were crucial in the development of the app after Dr. Brodie's study was carried out at the cutting-edge Sydney facilities of Neuroscience study Australia.

"People with Parkinson's disease must consider each and every step they take. When we asked them how much mental work it takes for them to walk, they frequently responded with "100%," according to him.

The metronome rhythm in the app is meant to take the place of the need to think about walking and assist with timing.

"This software can boost people's self-esteem and give them a sense of accomplishment by empowering them to take charge of their own health.

"I want my research to have an impact now, not in ten years," the researcher said. And I think that this app can already help Parkinson's patients all around the world.

Half of the 62 participants in the clinical trials with Parkinson's disease were able to use a version of the app to assist train their gait, while the other participants followed a standard walking regimen called the Otago Exercise Programme (OEP).

After 13 weeks, it was discovered through analysis of self-reported input from trial participants that those who followed the regular OEP training were working out for, on average, only 60 minutes per week, compared to 150 minutes for those who used the app.

In due course, a pertinent journal will publish the whole trial report, which will also include analysis of a related biomedical device that is now being done by a blinded statistician prior to approval by a clinical trial advisory board.

Based on the excellent reviews of those who used the app throughout the trial, researchers have independently developed the software further and expect to offer those with PD instant benefits.

It now includes targeted training sessions divided into five distinct walks, along with rest breaks, and directs users to practise walking at slow and fast rates in addition to a regular pace.

Metronome helps stabilise gait

"We're teaching them how to modify their gait. Because people with PD frequently have hypokinesia, which causes their movements to be smaller than they perceive them to be, they occasionally also need to picture their walking style, according to Dr. Brodie, who has since founded a spin-off business called Walking Tall Health.

"As a result, we are enticing them to take inflated steps, which will really resemble regular steps more closely.

"The feedback we received from the trials showed that the app's users really enjoyed the straightforward metronome beat they could hear on their phones, which helped to stabilise their stride.

The programme makes it easier for patients with Parkinson's disease to learn to walk. We advise them that even six minutes a day, three times a week, will still be helpful.

And we've seen that once individuals get involved and realise they are benefiting, they actually want to contribute more. They only need to press a single button on their smartphone to begin exercising, even if it's only walking up and down the hallway at home.

"That can significantly help someone with Parkinson's Disease whose main goal might be to be able to walk to their letterbox every day.

We also provide voice motivation for them in the app, and if you finish the training across several days, you can even "earn" a gold cup. Another drive for folks is all of that.

Dr. Martin Ostrowski, the chief science officer of Walking Tall Health, has Parkinson's disease.

And he adds: "It's all about creating trust, keeping it straightforward, and paying attention to what people need. The app aims to improve walking consistency and remove obstacles to efficient exercise.

We have seen that utilising this software to retrain gait for just a few minutes each day can have a significant impact. We will improve the subsequent app version the more people use our app and provide feedback.

"I have personally tried the software, and it is quite simple. It provides me the pulse I need to move without using too much mental energy. Parkinson's patients might not be aware because it comes naturally to them.

"I use the app once a day for around 10-15 minutes, walking a little over a km around the block, but patients with Parkinson's Disease can benefit from it in as little as six minutes.

According to Michael J. Fox, Parkinson's disease is a gift that keeps on giving. However, I believe that a tool like this app gives Parkinson's patients some control over their own care and helps them realise that they may still live long and fulfilling lives.

The software was further developed after the initial clinical trials with the aid of a Tyree Institute of Health Engineering (Tyree IHealthE) Catalyst Grant.

"Walking Tall Health addresses a significant unmet need experienced by people with PD and aligns with the Tyree IHealthE's vision of translating pioneering MedTech innovation," says Dr. Ian Goon, Head of Strategy and Innovation at Tyree IHealthE.

The $12 million ARC Research Hub for Connected Sensors for Health, headed by UNSW Scientia Professor Chun Wang, now includes Walking Tall Health as one of its industrial partners.

According to him, the smartphone software offers a fun tool that enables people with PD to walk to the beat of music, boost their self-assurance and walking speed, and enhance their stride.

With the additional research being conducted by Walking Tall Health in collaboration with the ARC Research Hub for Connected Sensors for Health, this technology will greatly assist Parkinson's patients globally.
