KneeStim intelligently uses neuromuscular electrical stimulation to contract quadriceps muscles in synchrony with patient movement, turning each joint loading instance into a muscle building repetition. This device is intended to provide improved, accelerated, cost-effective rehabilitation assistance to patients managing knee osteoarthritis or recovering from knee replacement surgery.

Quadriceps strength, or lack thereof, correlates with a patient's ability to manage their knee OA or to recovery fully from knee replacement surgery. Physical therapy is necessary to re-strengthen the quadriceps, but cost pressures and reimbursement policies are increasingly limiting the number of PT sessions a patient can have. KneeStim addresses the unmet need for optimized outpatient rehabilitation that focuses on quadriceps re-strengthening while minimizing time and money spent by both patient and provider.

Additionally, KneeStim's joint kinematics history may offer physicians and physical therapists feedback on patient progress that would only be achieved otherwise with expensive, non-mobile motion analysis in controlled settings. Collected kinematics data could be transmitted securely to a HIPAA-compliant network where progress and compliance data could be shared with patients, physicians, and therapists. Data could be used by providers to monitor patient compliance and to look for actionable insight on likelihood for readmission or continued rehabilitation difficulty. Patients would be able to observe similar data through their smartphone or a secure website portal.
