Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercise technologies fail to effectively prevent overtraining and injury by not allowing precise and localized muscle training, and existing methods using electrical muscle stimulation are limited by high intensity discomfort and inability to target specific muscle groups effectively.
Innovation Solution
An apparatus and method combining blood flow restriction with electrical muscle stimulation, using a blood flow occluding element and an electrical muscle stimulator to restrict blood flow and induce controlled muscle contractions, allowing for targeted and tolerable muscle training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical muscle stimulation is used to cause muscle contraction for rehabilitation and training, then muscle adaptive responses can be achieved, but intense discomfort occurs due to the required high intensity
Solution Approach 1:
The patent changes the physiological parameter of blood flow to the muscle by applying occlusive pressure, which allows electrical stimulation to be effective at much lower intensities. The occlusion creates metabolic stress and enhances muscle fiber recruitment, enabling adaptive responses without the high intensity that causes discomfort.
Solution Approach 2:
The patent introduces blood flow occlusion as an intermediary mechanism that mediates between the electrical stimulation and the muscle tissue. The occlusion modifies the physiological environment to enhance stimulation effectiveness while reducing the required intensity, thereby eliminating discomfort.
2Strength
If blood flow restriction is combined with active exercise to improve muscle hypertrophy and aerobic capacity, then low-intensity exercise loads can be used, but the exercise must be applied to the non-occluded limb and not to the ischemic muscle
Solution Approach 1:
The patent uses electrical stimulation as an intermediary to enable the occluded muscle to contract without requiring active exercise by the user. This overcomes the limitation that active exercise cannot be applied to the ischemic muscle, as the electrical stimulation directly induces contractions in the occluded limb.
3Reliability
If traditional exercise programs are used for clinical populations, then recovery and strength improvement can be achieved, but poor adherence and inappropriate exercise dosage occur
Solution Approach 1:
The system enables self-service through automated control of occlusion pressure and electrical stimulation parameters. The microprocessor-controlled device automatically adjusts settings based on user input and physiological feedback, allowing patients to independently manage their rehabilitation without constant clinical supervision, thereby improving adherence.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system monitors physiological responses and adjusts exercise dosage accordingly. This ensures appropriate exercise intensity and duration, preventing both under-dosing (which would not achieve recovery goals) and over-dosing (which could cause injury or discourage adherence).

Function Achieved in This Case
This approach enables controlled and localized muscle training, reducing the risk of overtraining and injury by allowing low-intensity exercise to induce significant muscular adaptations, improving strength and endurance while minimizing discomfort.
Implementation Method 1
a blood flow occluding element for restricting blood flow to a target muscle or muscle group in a user
Implementation Method 2
an electrical muscle stimulator comprising at least one electrode and a control unit which, upon activation, is effective to send low amplitude electric pulses through the target muscle or muscle group forcing the targeted muscle to contract

AI summary
An apparatus and method for ischemic muscle training or recovery provides coordinated blood flow restriction and electrical muscle stimulation. The apparatus includes a blood flow occluding element for restricting blood flow to a target muscle or muscle group in a user, and measuring resting systolic blood pressure (SBP). The apparatus also includes an electrical muscle stimulator including at least one electrode and a control unit which, upon activation, sends low amplitude electric pulses through the target muscle or muscle group forcing the targeted muscle to contract while the blood flow is restricted.
