KneeStim is intended to assist with quadriceps strengthening and re-education in concert with everyday activity through the integration of neuromusuclar electrical stimulation, motion-tracking hardware, and machine learning.
Quadriceps (thigh) strengthening is effective and necessary for improving/restoring knee function both before and after surgery. The quadriceps is responsible for joint extension, shock absorption, and weight distribution. The better the state of the quadriceps, the better the knee will be.
Research also shows that stimulation concomitant with muscle use gives better muscle strengthening outcomes. KneeStim enables that muscle use to be things you do all the time (walking up and down stairs, getting in and out of your car, walking around the block, etc.) by stimulating quadriceps muscle in time with gait and muscle loading instances.
* Accelerated, cost- and time-effective knee rehabilitation
* Automation of basic physical therapy outside of clinic
* Conservative treatment option, profit center and patient engagement for surgeons and therapists.
Aim: Patient Experience
* On-board motion-tracking hardware can be used to report clinically significant data (knee range of motion, activity levels, stride length/speed) to both patients and providers.
* Informal results of feasibility study indicate that stimulation timed with gait is less painful, easier to ignore than muscle stimulation applied while stationary
* Muscle strengthening through everyday activity enables patients to receive necessary treatment without detracting from work and family life.
Aim: Population Health
* Knee osteoarthritis: 14M affected; $5B market
* Knee replacement: 700k/year; $12B market
* 13 year avg. between diagnosis and replacement → pain, inactivity, lost wages, dissatisfaction
* Barriers to therapy for patients: time, cost, compliance.
Aim: Reduced Costs:
* Automation of basic physical therapy outside of the clinic can enable therapy to occur when patient time and/or coverage limits may not allow.
* The average TKR recipient will lose ~60% of their quadriceps strength after surgery.
* Patients with muscle weakness account for an additional $6k-$12k in post-operative costs related to knee replacement, are 44% more likely to be readmitted, and will generally have poorer post-op outcomes that will necessitate further intervention. KneeStim can help head off all of this.
Aim: Improved MD Work Life:
* KneeStim, provided to patients before and after surgery, can help improve surgical outcomes that impact physician reviews and hospital bottom lines.
* KneeStim can help physical therapists focus their attention on more complex interventions or activities, leaving quadriceps strengthening as something that can occur out of office.
* KneeStim, by offering unsupervised muscle stimulation, may help therapists serve more patients simultaneously during office visits.
* Working prototypes developed
* Four patents issued and owned; two pending
* Proof of concept data at Univ. of Texas at Austin
* Independent market research indicates significant MD/PT and patient interest.
