Definitions

  • the present disclosure relates to a system for providing focal vibration therapy.
  • Muscle pain often a symptom of various diseases, injuries, or disorders, remains one of the most prevalent health concerns. Its causes range from injury, overuse, and genetic predispositions to chronic stress or tension.
  • vibration therapy rely on controlled frequency and amplitude, allowing energy to be transmitted to specific areas of the body. These vibrations not only enhance muscle recovery but also contribute to cellular regeneration and improved musculoskeletal health.
  • current wearable vibration devices are associated with limitations. Most available devices are bulky, rigid, or stationary, restricting the user's mobility. Additionally, they often provide relief to only limited regions without delivering targeted vibrations deep into muscles and joints for specific therapeutic outcomes.
  • a system for providing focal vibration therapy comprising a wearable device having: one or more vibration actuators for providing focal vibration therapy; one or more sensors for sensing data associated with positional user data and physiological user data when the wearable device is worn by a user; and a controller.
  • the controller is configured to operate the wearable device in an assessment mode to assess functional musculoskeletal movement and mobility, where in the assessment mode, the controller is configured to access data from the one or more sensors when the user is carrying out movement(s) associated with the assessment, where said data forms sensor assessment data.

  • Focal vibration therapy also known as local vibration therapy
  • Focal vibration therapy is a type of physical therapy that involves applying vibration to specific areas of the body to, e.g., stimulate the muscles, promote healing of damaged tissue and strain, reduce pain and improve mobility.
  • Focal vibration therapy can be achieved by stimulating nerve endings and increasing blood flow. This can potentially help to reduce muscle spasms and inflammation, relieve muscle tension and improve range of motion. Additionally, the vibrations are thought to help release endorphins, which are natural pain-relieving chemicals in the body. Focal vibration therapy is often used to help alleviate muscle pain and stiffness associated with conditions such as fibromyalgia, back pain, and osteoarthritis.

  • Figures 5 and 6 show the system in treatment or assessment ‘modes’, respectively. These can occur separately or concurrently if needed.
  • Figure 7 shows an example of the mobile device (app) user interface 120 for the functional mobility or musculoskeletal assessment (i.e., the assessment session).
  • the user starts by wearing the wearable device 110 and initiating the assessment on the app 120 in step 16. Then the user performs a set of movements as guided by the mobile device (app) user interface 120 in step 17. While each movement is conducted by the user the wearable device measures and records movement data via a set of embedded sensors, then the wearable device sends the measurements wirelessly to the mobile device, which then displays the movement results on the mobile device (app) user interface. After each movement is completed, a new movement can be started. A prescribed series of movements is performed and records with the results displayed on the mobile device (app) user interface 120 in step 18.
  • the completed series of movement tests form a mobility or musculoskeletal function assessment with a resultant score for objective monitoring, diagnosis or progress tracking.
  • the score may be calculated by measuring movement and applying a weighting factor.
  • the weighting factors may consider variables related to the personal data of the user (age, weight, condition, injury etc.) and/or may be guided by clinically guided rules, e.g. used in physiotherapy for treating musculoskeletal conditions.
  • the assessment can be used for tracking progress, for ML to adjust treatment protocols and also to judge which movement cause MSK pain (as pain can be recorded before, during and after assessment steps).
  • Figure 8 shows an example of a typical algorithm used in this invention. Key features are: a) User personal and health information, musculoskeletal survey information entered via an App. Data processed with added Machine Learning (ML1). For ML1, a weighting score is applied to users based on their personalization data and MSK health data. This will put users into categories of disability due to their condition and also apply an ’red flags’ that may affect the treatment and assessment protocols, i.e., longer duration + higher amplitude treatments for users with low disability. Weighting score factors may consider variables related to the personal data of the user (age, weight, condition, injury etc.) and put users into groups of different treatment patterns.
  • ML1 Machine Learning
  • Mobility assessment data e.g., angular movement, movement speed, 3D movement signature
  • Mobility assessment data and user input Pain Score data e.g., user imputed using a scale of 1-10, which is a standard method to record pain (called NPRS)
  • NPRS a standard method to record pain
  • the formula of ((lx + 2y + 3z)/n) may be used, where “lx”, “2y” and “3z” are each a combination of a mobility measurement and a weighting factor, and n is the number of data points or mobility measurements used.

  • the coefficient e.g., 1, 2, and 3
  • the weighting factors applied to their respective mobility measurement e.g., based on their importance to the assessment.
  • Scores may be fed back to the wearable device using Machine Learning loops ML2/ML3 to adjust the treatment output of the focal vibration therapeutic treatment using the wearable device.
  • the personal and health information is used in the ML algorithms to adjust treatment protocols and can include any one or more of:
  • Demographics Age, gender, ethnicity, and race
  • Administrative and billing insurance data Administrative and billing insurance data

  • Body worn device capable of functional musculoskeletal joint movement assessment combined with a focal vibration therapeutic treatment.
  • Machine learning guided focal vibration treatment driven by an onboard objective assessment function that mimics a clinician directed musculoskeletal assessment.
