Where did the idea for using lasers come from?
I conducted a range of experiments with visual cues to establish that it would be the right solution for the product. I chose lasers specifically as they are capable of providing a very defined line and they offer the strength necessary to be visible in daylight.
How does it benefit people with Parkinson’s?
By preventing freezing episodes for Parkinson’s patients, Path Finder has the potential to prevent falling and increase confidence when walking. Preliminary tests conducted by our research partner have found a 55% reduction in FoG among affected individuals. Given that Parkinson’s disease is a progressive neurodegenerative disorder, it is expected that all patients will eventually develop FoG at some stage of diagnosis.
What stage are you at in the development of the product?
We are currently at prototyping stage and have developed a partnership with an academic institute in The Netherlands, Radboud University, with whom we will conduct patient testing. We are also working on a next phase prototype based on our learnings so far, and are planning a larger clinical trial study with Radboud University.

What has been the project’s biggest challenge?
It was paramount to develop a solution that met a lot of requirements in order to satisfy user needs. I wanted to create a product that was discreet and intuitive, which is why I decided to place the laser on the shoe. This allows the user to walk as they normally do, without needing to think about how to use the product. This is different from existing laser cue devices, such as canes, where the user has to place it in a certain location to ensure correct display of the laser line.
How have you funded the project?
We have won a range of grants that have helped fund our development so far. In addition to that, we have invested our own savings and time in making it happen.
How do you see Path Finder evolving?
Yes. Our initial results are very encouraging, so there is a great potential for the product to benefit users. This will increase quality of life and reduce the risk of falling, impacting both users and their families. It could also lead to significant reduction in costs for healthcare providers such as the NHS. Following successful user trials, we will seek regulatory approvals to establish Path Finder as a medical device, so that it can be recommended by healthcare professionals. We aim to have it on the market in approximately two years.

Why do you think more and more companies are turning to wearable technology as digital health solutions?
Wearable technology is non-invasive and don’t have any side effects when compared to drug treatment. Wearable technology also offers the possibility of gathering data, which opens up a range of options for personalised medicine and an increased understanding of self.
What are the next steps? What are your hopes for Path Finder, and people living with Parkinson’s?
Our next steps are to validate Path Finder in a larger user study. This will enable us to quantify the benefit of Path Finder in a statistically significant way. We hope to enable Parkinson’s patients using Path Finder to be more mobile. Parkinson’s is a disease that impacts the entire family of the sufferer. By improving the mobility, confidence and independence of the individual with Parkinson’s, we hope to increase quality of life for the family affected as well.
If there was one thing you could say to potential investors, what would it be?
Path Finder has the potential to greatly benefit the quality of life for individuals and their families. Injuries caused by falling currently cost the NHS close to a staggering £5 million every single day in the UK, while the falls prevention market is worth $50 billion according to InnovateUK. With up to 10 million people living with Parkinson’s worldwide, there is an opportunity for Path Finder to make significant cost savings for health services and, more importantly, create positive change for millions of lives.
