EMA FAQs

How does EMA work?

EMA is a mobile phone app that uses artificial intelligence to detect movement and scan the patient’s posture (hand movements, leg movements, standing posture and sitting posture) into a single index representing the severity of the patient’s condition. This index will identify a patient’s posture and follow up on routines recommended by the GP and monitor their progress.

What is the technology used to create EMA?

EMA has been built using artificial intelligence, neural networks and machine learning technology to detect movement and scan the patient’s posture (hand movements, leg movements, standing posture and sitting posture).

What is artificial intelligence?

In computer science, artificial intelligence (AI), sometimes called

machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans. Colloquially, the term "artificial intelligence" is often used to describe machines (or computers) that mimic "cognitive" functions that humans associate with the human mind, such as "learning" and "problem solving".

What is machine learning?

Machine learning (ML) is the scientific study of of algorithms and statistical models that computer systems use to perform a specific task without using explicit instructions, relying on patterns and interface instead. 

What is a neural network?

A neural network is a network or circuit of neurons, or in a modern sense, an artificial neural network, composed of artificial neurons or nodes. Thus a neural network is either a biological neural network, made up of real biological neurons, or an artificial neural network, for solving artificial intelligence (AI) problems. 

What is computer vision?

Computer vision is an interdisciplinary scientific field that deals with how computers can be made to gain high-level understanding from digital images or videos. From the perspective of engineering, it seeks to automate tasks that the human visual system can do.

Where is my data saved?

On a secure server in the NHS' EMIS system.

Is my data safe?

Yes, the EMIS has a safe server that cannot be accessed by unauthorised persons, and is fully compliant with the UK GDPR laws (https://ico.org.uk/for-organisations/guide-to-data-protection/guide-to-the-general-data-protection-regulation-gdpr/)

Does EMA work on every device?

EMA works on most smartphones built after 2016, iOS and Android.

How will my GP connect with me through EMA?

EMA has a doctor-patient communication functionality monitored through a unique Patient ID # that will track all interactions and communication. These will be in the form of alerts and messages.

Can I contact my GP through EMA?

The functionality is available, including a chat option. However, the speed at which responses are received will be subject to your GP's availability.

What if I don't use EMA to monitor my progress?

For your GP to monitor your progress and help you recover is contingent on your proper use of EMA as recommended. Your failure to use EMA will result in inaccurate monitoring and a delay in your progress and recovery.

Can I retrieve my own data and share it with a private doctor?

Yes, the premium version of EMA allows you to download reports of your progress and any other relevant data.

What if my app isn't working?

You can contact the EMA support team for any technical assistance. Usually, uninstalling and reinstalling the app will fix the problem.

Will my data be lost if I uninstall the app?

No, your data is stored in the NHS EMIS Server and not locally on your device.

Do I need an internet connection for EMA to function properly?

Certain functions like posture scanning and programmed reminders do not require internet. However, for data to be uploaded on the server, communications between the patient and the GP, and trigger functions to work, an internet connection is required.
