NOKIA ARA - EMPOWERING PATIENTS AND PRACTITIONERS THROUGH
PERSONALIZED ACL REHABILITATION
Nokia Ara is an Orthopedic tool that monitors patients with knee injuries and personalises their therapy.
PROJECT OUTLINE
The majority of sport injuries involve the lower body, particularly knee injuries where roughly 2,5 million people each year get injured. Once the knee is weakened the risk of injuries increases and in many cases the functioning will never go back to the way it used to be. The goal of this project was to empower patients who suffer from damage to the Anterior Cruciate Ligament (ACL) to recover their health in a faster and easier way.
CHALLENGE
Interviews, shadowing sessions and workshops were done with patients, athletes, surgeons and therapists to gain in depth understanding of the rehabilitation process. Today there are many problems, but the most important one is that every injury is unique, and requires a personalised rehabilitation process. Unfortunately therapy now is standardised and dependent on the therapists expertise. What if we could empower patients to recover their health in a faster and easier way through a personalised rehabilitation plan
RESULT
The result of this collaboration is Ara, the smart rehabilitation bracelet. Ara continuously monitors the injured knee to provide an increased amount of insights, which enables practitioners to take humanized, and data driven decisions to personalize the rehabilitation plan for each individual. It empowers patients to take an active part in their own rehabilitation by providing life and precise feedback on their activities throughout the day.
MEET ARA
Meet Ara, the smart rehabilitation bracelet! Through constant sensing Ara provides an increased amount of insights for the therapists to take humanized and data driven decisions. Which results in a more informed, easier, faster and reassured rehabilitation experience for the patient. The concept consists of three main items, a bracelet (to monitor the patients injury), an app (to communicate and adapt the therapy) and a charging unit. Since patients will be wearing Ara throughout the biggest part of the day, they do not wish to wear technology visually, but just get the benefits. Because of this a minimal design was created on the outside of the product.
RETHINKING THE REHABILITATION PROCESS
To approach the design challenge first a new scenario had to be created in which the current rehabilitation process was challenged an optimised. The resulting scenario now works as follows: As soon as an individual gets injured, he/she receives Ara, who starts to monitor the injury. This information is then shared with the therapist which enables him/her to take data driven decisions and inform the patient about their injury and how to get better. Through this, patients will receive a personalised rehabilitation experience which ends with teaching individuals how to prevent the injury from happening again. Furthermore this device can be used by individuals and athletes who then reduce the risk of injuries from happening by working on preventive training. All this data can then be collected in a general database which in turn helps healthcare providers get a better understanding of the injury and optimise the rehabilitation processes for each individual.
CALLIBRATING ARA
Patients receive Ara form their therapists who will first calibrate the device on the healthy knee of the patient. This is to gain a so called "zero point" as a reference what strength the other knee should have at the end of the rehabilitation.
By doing this the therapist ensures that the patient will regain proper balance and the therapy has its goals optimised for each individual.
DIRECT FEEDBACK
One of the biggest problems with rehabilitation is to know when you have done enough exercises for the day. If patients push themselves too far, they risk further injuring the knee, instead of rehabilitating it.
To ensure that patients don't push themselves too far Ara has several vibration engines integrated into the bracelet. These will vibrate when direct feedback is needed, for example when they need to take a break.
REHABILITATION COACH
When patients have to perform exercises for their therapy it is important that they learn the correct technique. This since it will help them to reduce the risk of future injuries from happening.
Ara comes with an App that will give life feedback to patients when performing these exercises and will serve as their personal rehabilitation coach.
