[00:00:06.838]ForceWIN10 uses a little brawn
[00:00:09.531]to assess the brain.
[00:00:13.293]ForceWIN10 measures muscle force
[00:00:15.281]in the jaw, mouth, and fingers
[00:00:17.236]to evaluate the health of the brain.
[00:00:19.641]The system can be used to diagnose and treat conditions
[00:00:22.515]ranging from stroke and traumatic brain injury
[00:00:25.563]to Parkinson's and ALS.
[00:00:27.909]ForceWIN10 originated in the lab
[00:00:29.918]of University of Nebraska researcher, Steven Barlow.
[00:00:33.736]It allows us to examine the strength
[00:00:36.833]of these muscle systems.
[00:00:38.384]But more importantly, this system allows us to
[00:00:41.994]understand how these muscles are controlled
[00:00:45.306]at precise force levels that you need for
[00:00:48.525]manipulating objects, for generating speech,
[00:00:51.988]for eating, facial gestures.
[00:00:55.220]It can also be used as a system for therapeutics.
[00:00:59.912]The wireless instrument
[00:01:01.122]includes a double-sided mouth guard
[00:01:03.444]that measures jaw strength,
[00:01:05.596]a second force sensor that measures movement
[00:01:07.840]of the upper or lower lip,
[00:01:10.239]a third instrument that samples the force of the tongue,
[00:01:14.323]and a small button that can be pinched
[00:01:16.623]to measure force in the fingers.
[00:01:18.899]So with this one instrument module,
[00:01:21.751]all interfaced to this computer
[00:01:24.545]by way of Bluetooth technology,
[00:01:27.363]we can sample four different oral-facial structures.
[00:01:31.179]It takes approximately six to seven minutes
[00:01:34.343]to do a diagnostic assessment for any given structure
[00:01:38.311]on this computer program, known as ForceWIN10.
[00:01:42.117]The system is set up like a video game.
[00:01:44.567]Patients try to generate the appropriate level of force
[00:01:47.729]needed to reach a target on the screen.
[00:01:50.179]There's this red line, and this is your target force.
[00:01:53.721]So, when you hear the beep, you are going to
[00:01:56.276]apply force with your lower lip
[00:01:58.622]and reach that red line as rapidly
[00:02:00.680]and accurately as possible.
[00:02:02.798]A test of an adult stroke patient
[00:02:04.649]indicates that damage to one side of the brain
[00:02:07.526]affects strength in the opposite finger.
[00:02:09.976]In fact, this patient is showing an overshoot
[00:02:12.518]roughly eight times the target.
[00:02:16.186]And you can also get a sense for
[00:02:17.959]the instability in this force contraction.
[00:02:21.317]Information collected from patient testing
[00:02:23.488]answers a variety of questions:
[00:02:25.628]How fast do the muscles contract or relax?
[00:02:28.514]How long does it take them to fatigue?
[00:02:30.986]Therapy can be tailored to meet individual needs.
[00:02:34.768]We can turn the system around and use it
[00:02:37.160]for neurotherapeutics to help
[00:02:40.499]prescribe a treatment program for these patients
[00:02:43.789]as they go through motor rehabilitation.
[00:02:46.764]You're just gonna pinch, and then when you relax,
[00:02:49.042]you just let your hand open.
[00:02:51.191]If we determined that most of
[00:02:53.711]the impairment was in the hand or the fingers,
[00:02:56.807]we can design a very specialized
[00:03:00.027]motor feedback program, using ForceWIN.
[00:03:03.360]It operates much like a video game in which
[00:03:06.500]the patient is able to see his or her own
[00:03:10.029]force signals in real time.
[00:03:13.091]And they get an opportunity to practice
[00:03:16.527]and repeat force productions
[00:03:19.716]at different target levels.
[00:03:22.856]And it's this practice effect
[00:03:25.066]that stimulates the brain
[00:03:26.928]and helps it to establish new connections
[00:03:29.942]and improve their motor control.
[00:03:32.539]The ForceWIN10 system is cost-effective,
[00:03:35.140]and accessible for clinicians in physical therapy,
[00:03:38.026]speech-language pathology, even dentistry
[00:03:41.048]or maxillofacial surgery.
[00:03:43.315]It can be used in patients beginning at about age five.
[00:03:47.100]And for the very first time,
[00:03:49.032]we'll be able to get bedside with acute strokes.
[00:03:52.298]So these are patients that have sustained
[00:03:56.081]the injury and the infarct.
[00:03:58.599]Within a matter of hours,
[00:04:00.657]we'll be able to start assessing and formulating
[00:04:04.407]diagnostic and therapeutic plans for these patients.
[00:04:08.179]Nationwide trials with ForceWIN10
[00:04:10.354]will include Madonna Rehabilitation Hospital in Lincoln,
[00:04:13.620]and the University of Nebraska Medical Center.
