What does the app do?

Nymbl describes itself as an app-based digital health platform. It involves a combination of balance and cognitive games and training to target improving balance and mobility – especially for older populations. It's designed to improve balance and mobility for people with a recognised risk of falling who are over the age of 50 years.

The app has an initial questionnaire, training modules, feedback and calendar options to ensure that training can be tracked and progressed at an appropriate level.

It would be most helpful for people with a history of falling, or with concerns around balance or mobility. It's unlikely that younger people without balance concerns would get significant benefit from the app.

It's acknowledged that currently in Aotearoa New Zealand, if someone is having a fall/accident, they are likely to get physiotherapy input aimed at improving their balance. However, if they haven’t yet had a fall, but are concerned about their balance, they might not necessarily get health professional input. This app will be especially helpful to ensure that those in that group can work on their balance, and hopefully prevent future falls.

✔ Questionnaire and education: The questionnaire at the start of the app is really good. It allows the app to get a good understanding of the user’s current levels of balance and mobility. I like with this that there is an explanation with each question, which gives relevance.
Eg, “I need to push up with my hands to stand from a chair”.
Why: This can be a sign of leg muscle weakness.

✔ Feedback functionality: At the end of each session, a user gives feedback on level of difficulty (too hard, too easy, just right) and any pain experienced throughout the session. This ensures it's aimed at a correct level.

✔ Wide range of cognitive activities: The app works off the established premise that combining balance and cognitive activities is an effective way to improve balance (and cognition). There's a nice range of varied activities, which have recently been updated, and this included: including memory, trivia, puzzles and math, what is it and words sections. This variety will help keep users interested.

✔ Calendar/reminder function: Helps users to ensure that they can use the app at the recommended 3 times weekly frequency.

✘ Only available in English.

✘ It would be great to have a health professional aspect to the app and allow a GP/physio/other health professional to be able to prescribe or choose particular exercises for a patient. This is not a con for current use – more of an opportunity for development.
