Frequently Asked Questions

🧲 Hardware

  • BioSensr is used by sports professionals to monitor muscle activation during isometric hamstring holds.

    It provides performance insights to help guide training and loading decisions.

    BioSensr is not a medical device and is not used for diagnosis or rehabilitation.

  • BioSensr is designed for monitoring the biceps femoris and semitendinosus during isometric hamstring testing as outlined in the Instructions for Use.

    Use outside this protocol is not recommended.

  • No. BioSensr sensors are powered via USB-C connection to a laptop.

    The laptop must be operated on battery power (not connected to mains) during measurements.

  • All data is stored locally on your selected save path.

    BioSensr does not use cloud storage or remote data transmission.

    Users are responsible for managing and backing up their data.

  • BioSensr is designed for high-performance environments:

    • Bend tested: 100,000 cycles

    • Drop tested: up to 2 metres

    • Tensile strength: 10 kg

    • Maximum strain: 50 %

    Despite its durability, handle with care and avoid excessive twisting or pulling.

💻 Software

  • Mac: macOS (M1 or higher) with MATLAB Runtime (arm64)
    Windows: Windows 10+ (64-bit) with MATLAB Runtime

    Full installation instructions are provided in the official Instructions for Use.

  • No. Updating will not remove stored session data.

    However, user preferences may reset.

🏋 Testing Protocol

  • BioSensr is designed for isometric hamstring holds. This can be performed using:

    • VALD NordBord (default)

    • A stable bench setup (alternative)

    • GHD Machine

    Full setup instructions are provided in the official Instructions for Use.

  • BioSensr is validated and intended only for isometric hamstring holds as described in the Instructions for Use.

    Use for other movements or muscle groups is not supported.

  • No. BioSensr is a performance monitoring tool only.

    It does not diagnose injury or medical conditions and should not replace professional clinical judgement.

🧽 Cleaning & Care

  • Sensors can be gently rinsed and cleaned with water and a sponge.

    Avoid water entering the USB-C port and allow sensors to fully dry before storage.

  • Straps should be washed cold and air dried.

⚡️ Signal Quality

    • Operate the laptop on battery power

    • Minimise nearby electrical interference

    • Ensure good skin contact with electrode gel
