Biodex
| This isokinetic equipment is most often used in strength assessment. It is also used to normalize electromyographic (EMG) data to a percentage of a person´s maximal voluntary isometric contraction. | |

MotionMonitor and Bertec Force Plates
The MotionMonitor is used to assess human movement. The force plate underneath the feet of the person in this picture acquires the ground reaction forces and center of pressures provided by the subject. This example shows the performance of a drop jump. Interfaced together, we can get a more comprehensive picture of the movements, forces, and moments necessary to complete a task. |

Vermont Knee Laxity Device (VKLD)
| This device allows for a precise examination of knee forces and anterior tibial displacements while under simulated weight bearing condition and non-weight bearing conditions. A MotionMonitor (PhaseSpace) system is integrated with the VKLD to acquire the forces and motion occurring at the knee. | |

Lower Extremity Perturbation Device (LEPD)
| This device initiates a rotational twisting motion about the lower extremity when one of the cables are released from the hip. It is unknown to the subject as to which cable will be released and when it will be released. When interfaced with the MotionMonitor, Bertec Force Plate, and Surface EMG, we can get a comprehensive picture of the overall reaction of the subject to this twisting perturbation. | |

Surface Electromyography
| Surface EMG is used to measure the electrical activation of muscle. Pictured is a double leg landing task and a typical raw EMG signal of the Quadriceps, Hamstrings, and Gastrocnemius muscles associated with this activity. | |

Anatomical Variables
| A variety of anatomical measurements are taken in an effort to identify specific factors that contribute to mal-alignment and potentially increase a person´s injury risk. |
