We use a broad range of techniques to study the biomechanics and neuromechanics of movement and muscle contraction. Our laboratory, located on the VUB Main Campus, includes extensive space for diverse movement analyses and is equipped with dedicated, state-of-the-art neuromechanical instruments. All measurement systems are fully time-synchronized to ensure precise data integration.
Ultrasound imaging
- Multiple Telemed ArtUS systems with veterinary (flat) transducers enable high-speed dynamic imaging of muscles and tendons (up to 150 fps). Two Usono Probefix devices allow secure transducer attachment to limbs during dynamic movements, ensuring stable and repeatable imaging.
Electromyography
- Wireless Delsys Trigno system with 16 Trigno Avanti sensors for surface detection of muscle activation during full body movements. Includes an external trigger box for data synchronization with other devices.
- Digitimer Neurolog system with a 4-channel isolation amplifier (NL820A), low-/high-pass analog filters for precise neural signal acquisition.
- Indwelling fine-wire electrodes for detecting muscle activation or motor unit activity in deep or small muscles.
Muscle stimulation
- Digitimer DS7R constant-current electrical stimulator for surface stimulation of muscles and nerves.
- Indwelling fine-wire for intramuscular electrical stimulation.
Torque measurements
- BIODEX System 4 Pro dynamometer for measuring joint torque and controlling joint rotation speed during isometric, passive, concentric, and eccentric actions.
Motion capture
- OptiTack V120 motion capture system with three built-in cameras for fast and accurate 3D motion capture.
Split-belt instrumented treadmill
- Treadmill with embedded force plates for recording ground reaction forces. The system allows precise of belt speeds, including independent speed adjustments for each belt.
Data integration and synchronization
- Cambridge Electronic Design (CED) Micro4 - 1401 data acquisition system with Spike2 software for real-time data integration, synchronization, and biofeedback of raw and processed signals.
Motion sensors
- Delsys Trigno Avanti sensors include inertial measurement units (IMUs) for collecting 3D accelerometer and gyroscope data.
- Vicon Blue Trident IMUs can be synchronized with our Vicon motion capture system for integrated motion analysis.
