So, this is the Impulse Pro Trainer. We use this device a lot in the clinic for upper extremity issues, particularly rotator cuff problems, labral issues, even for neck instability, and neck pain. So this device is very unusual in that… I’ll have you come in here and hold this for me… In that we actually have a weight here that Trevor has the slide side to side. So typically, if you think about exercise equipment, you have to move weights up and down. But in this case, he actually has a mass and he has to slide it side to side by the action of what he does. The reason that’s so powerful is he has to decelerate that weight and then swing it the other way and that actually creates a big, what we call, eccentric load, and so that makes his rotator cuff muscle, and particularly his tendon, work really hard. And that really helps stimulate a heal, if you prescribe this the proper way. So this is the Impulse. A great device here we use at LifeMotion Physical Therapy.
