The FORCE Lab is located in the Therapeutic Associates-Bend Physical Therapy clinic which is housed in The Center Orthopedic & Neurosurgical Care & Research next to St. Charles Medical Center.
Our lab space is approximately 2,000 square feet in the middle of a 10,000 sqare foot physical therapy clinic.
The lab has a suite of sophisticated equipment, including an eight-camera motion analysis system, two “force plates,” a treadmill with a metabolic cart, ultrasound equipment, and video cameras.
Vicon Three-Dimensional Motion Analysis Equipment: The FORCE Lab is equipped with a state-of-the-art 3D optical motion capture system as well as high-definition video cameras for synchronizing video with 3D kinematic data.
Three-Dimensional Motion Capture: 3D segmental and joint kinematics are captured via reflective markers placed on the subject and an 8-camera Vicon MX system, which includes 2.0 and 4.0 megapixel lenses, a full-frame resolution up to 690 Hz, and Near-Infra-Red (NIR) strobes that are outdoor capable.
High-Definition (HD) Digital Video: two Bonita 720c cameras provide video that is synchronized with 3D motion data, at a rate of up to 120 frames per second. These cameras provide sagittal and frontal plane views of all data collection sessions and can be moved within the lab to optimize movement analyses as needed.
Vicon Nexus software: a Life-science specific motion capture software system, Nexus facilitates simple optical and dynamic video calibration, allows visualization of 3D marker tracking and video in real-time, and synchronizes kinematics and video with analog kinetic (i.e. force plate) data. Post-processing in Nexus results in data that can be sent to additional software programs for statistical analysis, visualization, and presentation.
Force Platforms: Kinetics (forces and moments) of any weight-bearing movement or task can be measured by two AMTI biomechanics force platforms (or force plates). These force plates have been seamlessly embedded into the floor of the FORCE lab, have a capacity of 2000 lbs, a capture rate of up to 2000 Hz, and < 2% crosstalk on all channels.
Biodex System 3 Dynamometer: The Biodex dynamometer is the gold standard in measuring muscle strength around any joint using isokinetic dynamometry. HUMAC software from CSMi gives us the capability to produce graphic reports with normative data for study participants and patients.
Vicon Motus 10.0 System: Using our Canon ZR960 Mini DV camera and data capture software from CONTEMPLAS called TEMPLO, Motus allows quick and efficient analysis and reporting of 2D video of any movement in any setting. This system also allows for synchronization with analog data as well as future expansion to up to 12 cameras in order to capture multiple views simultaneously.
Post-Processing Software: Additional software programs work with processed data and models of each subject’s individual musculoskeletal geometry to generate data for further analysis. Results can then be used for statistical analysis, visual & graphical outputs for research publications and conference presentations, and educational tools for use in the classroom.
C-Motion Visual 3D: A software package for motion capture data analysis and modeling, Visual 3D (V3D) applies processed data from Vicon Nexus to a biomechanical model of the individual performing movement tasks in the lab. From there, it is capable of accurately reporting and displaying a number of biomechanical variables including joint angles, moments, power output, and ground reaction forces using inverse dynamics. With V3D’s built-in graphing and reporting tool, as well as its ability to quickly export to other programs such as Microsoft Excel, Matlab, and SPSS, motion capture results are cleanly displayed and analyzed.
Vicon Polygon: An additional reporting and presentation tool, Polygon facilitates sharing of data and results in the classroom or professional conference setting. Fully integrated with Vicon Nexus software, it also allows for real-time biofeedback visualization.
Metabolic Testing Equipment: KORR Medical Technologies, CardioCoach CO2™ and Trackmaster Treadmill: This system allows for the measurement of VO2 Max, Peak VO2, and anaerobic threshold. It provides V-slope and Respiratory Quotient (RQ) data which can be used to customize an individual's exercise plan. CardioCoach CO2™ also measures Resting Metabolic Rate (RMR) and reports Respiratory Quotient (RQ) to maximize efforts in personalized weight loss programs. The Trackmaster Treadmill is interfaced to the CardioCoach CO2™ which allows the software to control the treadmill incline, speed, or resistance throughout testing.
The Alter-G treadmill utilizes unweighting technology developed by NASA to provide a gentle and uniform lifting force to the body, allowing the user to walk or run with forces ranging from 20 to 100 percent of their body weight. In this way, it substantially reduces impact forces on the joints as well as stresses on the muscles, without altering the mechanics of running and walking. The Alter-G is a powerful tool for rehabilitation of lower extremity injuries, allowing a faster and safer return to activity. It is also increasingly used for sports performance training to reduce frequency of injuries, increase fitness, and speed up recovery.

Esaote Aquila Pro Rehabilitative Ultrasound Imaging (RUSI)
RUSI uses ultrasound technology to provide real-time imaging of muscle activation during functional movements and therapeutic exercises. By utilizing RUSI during both diagnosis and treatment, physical therapists enhance the rehabilitation experience and outcomes in conditions such as lumbar instability, general low back pain, and pelvic floor dysfunction. The real-time feedback provided by RUSI allows instantaneous examination of deep muscle fiber contraction (for example, in the abdominal wall or spinal extensors), and facilitates optimal neuromuscular activation and therapeutic exercise prescription.
The FORCE Lab’s primary data collection computer is optimally configured for the Vicon motion capture system, including state-of-the-art processing and graphics capabilities and additional memory in the form of two built-in SSD hard drives. It is connected to a dedicated server with automatic data backup protocols in place. Three additional staff and student desktop workstations with high-speed processing and graphics are located in the FORCE lab offices.
