Social mobile gaming boosts rehabilitation for physically impaired patients

Balloon Buddies game

A video game that enables healthy volunteers to play with patients who have physical impairments may improve their rehabilitation, suggests study.

The researchers from Imperial have designed a video game called Balloon Buddies, which is a tool that enables those recovering from  conditions such as a stroke to engage and play together with healthy volunteers such as therapists and family members as a form of rehabilitation.

Balloon Buddies is designed to level the playing field  by allowing healthy participants to support the less abled player. The researchers have shown that this type of collaboration makes it more rewarding for the less-abled partner, more challenging for the better partner, and overall more fun for both, as they  have to continuously work together to score points.  

The team have trialled Balloon Buddies by getting patients to play it on their own in single player mode and then partnered with healthy  volunteers during dual player gameplay. They found that the performance of the patient was boosted when they played with a healthy volunteer, compared to if they were playing the game on their own. In addition, they found that the poorer a patient’s single player performance was, the greater the improvement seen when they played  with another during dual-player mode. 

These findings published today in the Journal of NeuroEngineering and Rehabilitation (JNER), suggest that by  increasing engagement with healthy volunteers, compared to playing alone, patients may be more likely to increase the effort they put into training, which could ultimately lead to greater gains in physical performance.

While the pilot study was limited to 16 patients and 32 healthy participants playing in 16 pairs, the researchers believe this form of rehabilitation through gaming may be beneficial to patients recovering from other illnesses such as musculoskeletal injuries, arthritis, and cerebral palsy.   The researchers are aiming to further develop the game alongside new multiplayer concepts and show that it can be used in different settings including patients training with their therapist or with other patients, in community centres or even remotely at home.

Dr Michael Mace, lead author from the Department of Bioengineering at Imperial College London, said: “Video  games are a great way of providing repetitive exercise to help patients recover from debilitating illnesses.  However, most games are designed for users to play on their own, which can actually discourage and isolate many patients. We developed the Balloon  Buddy game to enable patients to train with their friends, family or caregivers in a collaborative and playful manner. The technology is still being developed, but we  have shown that playing jointly with another individual may lead to increased  engagement and better outcomes for patients.”

Balloon Buddies uses animation, sounds, and vibration-feedback, similar to conventional video games. It requires users to balance a ball on a beam, which is lifted  at each of its ends by balloons controlled by the players.  The main aim of the game is for the players to vary the height of the beam so that the ball collides with moving targets in order to collect points.  Players are also required to work together to  keep the beam horizontal so that the ball doesn’t roll off the platform.  It is played with a wireless handgrip called GripAble, enabling  people with arm weakness to control video games on any standard tablet device.

In the study, the researchers tested the game on 16 patients who had arm weakness following a stroke with a healthy volunteer  over three months at Charing Cross Hospital, which is part of Imperial College Healthcare NHS Trust, in 2016.  Previously, the game was also tested on 16 healthy pairs with different baseline abilities.

The team will now carry out a larger study to examine whether the game leads to more efficient learning and to examine  if patients are more motivated to train for longer periods.  They will also explore social implications of interaction such as the effect of patients playing with a relative versus a stranger.

The Balloon Buddies game is an example of the work of the Imperial Academic Health Science Centre (AHSC).  This is a partnership  between Imperial College London and three NHS Trusts, which aims to improve patient outcomes by harnessing scientific discoveries and translating them as quickly as possible into new diagnostics, devices and therapies, in the NHS and beyond.
