0:00:00.903,0:00:06.376
When I was growing up, I really [br]liked playing hide-and-seek a lot.

0:00:06.383,0:00:10.492
One time, though, I thought climbing[br]a tree would lead to a great hiding spot,

0:00:10.492,0:00:13.395
but I fell and broke my arm.

0:00:13.395,0:00:17.478
I actually started first grade[br]with a big cast all over my torso.

0:00:18.178,0:00:22.323
It was taken off six weeks later,[br]but even then, I couldn't extend my elbow,

0:00:22.323,0:00:25.376
and I had to do physical therapy[br]to flex and extend it,

0:00:25.376,0:00:28.271
100 times per day, seven days per week.

0:00:29.021,0:00:32.063
I barely did it, because[br]I found it boring and painful,

0:00:32.063,0:00:35.694
and as a result, it took me[br]another six weeks to get better.

0:00:36.684,0:00:39.548
Many years later, my mom[br]developed frozen shoulder,

0:00:39.548,0:00:44.044
which leads to pain[br]and stiffness in the shoulder.

0:00:44.044,0:00:47.155
The person I believed for half of my life[br]to have superpowers

0:00:47.155,0:00:50.463
suddenly needed help[br]to get dressed or to cut food.

0:00:51.474,0:00:54.283
She went each week to physical therapy,[br]but just like me,

0:00:54.283,0:00:56.187
she barely followed the home treatment,

0:00:56.187,0:00:59.228
and it took her[br]over five months to feel better.

0:00:59.848,0:01:02.503
Both my mom and I[br]required physical therapy,

0:01:02.503,0:01:05.266
a process of doing a suite[br]of repetitive exercises

0:01:05.266,0:01:09.794
in order to regain the range of movement[br]lost due to an accident or injury.

0:01:09.794,0:01:12.171
At first, a physical therapist[br]works with patients,

0:01:12.171,0:01:15.134
but then it's up to the patients[br]to do their exercises at home.

0:01:15.134,0:01:18.923
But patients find physical therapy[br]boring, frustrating, confusing

0:01:18.923,0:01:21.844
and lengthy before seeing results.

0:01:21.844,0:01:26.837
Sadly, patient noncompliance[br]can be as high as 70 percent.

0:01:26.837,0:01:30.226
This means the majority of patients[br]don't do their exercises

0:01:30.226,0:01:34.011
and therefore take[br]a lot longer to get better.

0:01:34.011,0:01:36.797
All physical therapists agree[br]that special exercises

0:01:36.797,0:01:38.957
reduce the time needed for recovery,

0:01:38.957,0:01:41.333
but patients lack[br]the motivation to do them.

0:01:42.393,0:01:46.898
So together with three friends,[br]all of us software geeks,

0:01:46.898,0:01:48.987
we asked ourselves,

0:01:48.987,0:01:53.585
wouldn't it be interesting if patients[br]could play their way to recovery?

0:01:53.585,0:01:56.441
We started building MIRA,[br]A P.C. software platform

0:01:56.441,0:01:59.339
that uses this Kinect device,[br]a motion capture camera,

0:01:59.339,0:02:03.072
to transform traditional exercises[br]into video games.

0:02:03.702,0:02:08.364
My physical therapist has already set up[br]a schedule for my particular therapy.

0:02:08.364,0:02:10.616
Let's see how this looks.

0:02:13.867,0:02:16.746
The first game asks me[br]to fly a bee up and down

0:02:16.746,0:02:19.277
to gather pollen to deposit in beehives,

0:02:19.277,0:02:21.738
all while avoiding the other bugs.

0:02:21.738,0:02:24.964
I control the bee by doing[br]elbow extension and flexion,

0:02:24.964,0:02:28.846
just like when I was seven years old[br]after the cast was taken off.

0:02:29.865,0:02:32.929
When designing a game,[br]we speak to physical therapists at first

0:02:32.929,0:02:35.856
to understand what movement[br]patients need to do.

0:02:35.856,0:02:37.527
We then make that a video game

0:02:37.527,0:02:40.722
to give patients simple,[br]motivating objectives to follow.

0:02:41.312,0:02:43.239
But the software is very customizable,

0:02:43.239,0:02:46.652
and physical therapists can also[br]create their own exercises.

0:02:47.192,0:02:49.183
Using the software, my physical therapist

0:02:49.183,0:02:51.471
recorded herself performing[br]a shoulder abduction,

0:02:51.471,0:02:53.664
which is one of the movements[br]my mom had to do

0:02:53.664,0:02:55.361
when she had frozen shoulder.

0:02:55.361,0:02:58.819
I can follow my therapist's example[br]on the left side of the screen,

0:02:58.819,0:03:02.511
while on the right, I see myself[br]doing the recommended movement.

0:03:02.511,0:03:04.554
I feel more engaged and confident,

0:03:04.554,0:03:07.015
as I'm exercising alongside my therapist

0:03:07.015,0:03:10.870
with the exercises my therapist[br]thinks are best for me.

0:03:10.870,0:03:13.795
This basically extends the application[br]for physical therapists

0:03:13.795,0:03:18.323
to create whatever exercises[br]they think are best.

0:03:18.323,0:03:21.574
This is an auction house game[br]for preventing falls,

0:03:21.574,0:03:24.569
designed to strengthen muscles[br]and improve balance.

0:03:24.569,0:03:27.564
As a patient, I need to do[br]sit and stand movements,

0:03:27.564,0:03:29.422
and when I stand up,

0:03:29.422,0:03:31.767
I bid for the items I want to buy.

0:03:31.767,0:03:33.880
(Laughter)

0:03:33.880,0:03:36.875
In two days, my grandmother[br]will be 82 years old,

0:03:36.875,0:03:39.290
and there's a 50 percent chance[br]for people over 80

0:03:39.290,0:03:41.171
to fall at least once per year,

0:03:41.171,0:03:44.259
which could lead to a broken hip[br]or even worse.

0:03:44.259,0:03:48.415
Poor muscle tone and impaired balance[br]are the number one cause of falls,

0:03:48.415,0:03:51.526
so reversing these problems[br]through targeted exercise

0:03:51.526,0:03:54.196
will help keep older people[br]like my grandmother

0:03:54.196,0:03:57.029
safer and independent for longer.

0:03:57.029,0:03:59.514
When my schedule ends,[br]MIRA briefly shows me

0:03:59.514,0:04:02.693
how I progressed throughout my session.

0:04:03.553,0:04:05.620
I have just shown you[br]three different games

0:04:05.620,0:04:08.113
for kids, adults and seniors.

0:04:08.113,0:04:10.942
These can be used with orthopedic[br]or neurologic patients,

0:04:10.942,0:04:13.886
but we'll soon have options[br]for children with autism,

0:04:13.886,0:04:16.311
mental health or speech therapy.

0:04:16.661,0:04:18.999
My physical therapist[br]can go back to my profile

0:04:18.999,0:04:21.990
and see the data gathered[br]during my sessions.

0:04:21.990,0:04:24.660
She can see how much I moved,[br]how many points I scored,

0:04:24.660,0:04:26.610
with what speed I moved my joints,

0:04:26.610,0:04:27.841
and so on.

0:04:27.841,0:04:31.118
My physical therapist can use all of this[br]to adapt my treatment.

0:04:31.881,0:04:33.947
I'm so pleased this version is now in use

0:04:33.947,0:04:37.244
in over 10 clinics[br]across Europe and the U.S.,

0:04:37.244,0:04:39.197
and we're working on the home version.

0:04:39.197,0:04:43.670
We want to enable physical therapists[br]to prescribe this digital treatment

0:04:43.670,0:04:47.310
and help patients play their way[br]to recovery at home.

0:04:48.030,0:04:51.473
If my mom or I had a tool like this[br]when we needed physical therapy,

0:04:51.473,0:04:54.519
then we would have been more successful[br]following the treatment,

0:04:54.519,0:04:58.049
and perhaps gotten better a lot sooner.

0:04:58.049,0:04:59.651
Thank you.

0:04:59.651,0:05:02.031
(Applause)

0:05:02.031,0:05:05.607
Tom Rielly: So Cosmin, tell me[br]what hardware is this

0:05:05.607,0:05:07.470
that they're rapidly putting away?

0:05:07.470,0:05:09.710
What is that made of,[br]and how much does it cost?

0:05:09.710,0:05:12.789
Cosmin Milhau: So it's[br]a Microsoft Surface Pro 3 for the demo,

0:05:12.789,0:05:16.534
but you just need a computer[br]and a Kinect, which is 120 dollars.

0:05:16.534,0:05:19.981
TR: Right, and the Kinect is the thing[br]that people use for their Xboxes

0:05:19.981,0:05:21.052
to do 3D games, right?

0:05:21.052,0:05:24.113
CM: Exactly, but you don't need the Xbox,[br]you only need a camera.

0:05:24.113,0:05:26.875
TR: Right, so this is less[br]than a $1,000 solution.

0:05:26.875,0:05:29.458
CM: Definitely, 400 dollars,[br]you can definitely use it.

0:05:29.458,0:05:32.254
TR: So right now, you're doing[br]clinical trials in clinics.

0:05:32.254,0:05:32.993
CM: Yes.

0:05:32.993,0:05:35.713
TR: And then the hope is to get it[br]so it's a home version

0:05:35.713,0:05:37.392
and I can do my exercise remotely,

0:05:37.392,0:05:40.922
and the therapist at the clinic[br]can see how I'm doing and stuff like that.

0:05:40.922,0:05:41.989
CM: Exactly.

0:05:41.989,0:05:43.843
TR: Cool. Thanks so much.[br]CM: Thank you.

0:05:43.843,0:05:44.584
(Applause)
