Zenolink 3D Hitting & Power Analysis

What is Zenolink?

Zenolink is a diagnostic tool designed to provide information about functional performance during a specific activity. Data produced by Zenolink testing quantifies both performance and injury potential through biomechanical measurements that include joint ROM, body segment coordination and outcome parameters.

Zenolink was designed for the clinician: physical therapist, chiropractor, trainer.

…more about Zenolink Technology

Using standard video cameras allows un-tethered and un-restricted data collection – NO MARKERS, NO WIRES. Data can be captured in all environments of interest including controlled and uncontrolled situations: indoor, outdoor, practice/game, and actual workplace setting.

Since the only hardware required for collection are video cameras, it is easy and inexpensive to set up one or even multiple collection stations at as many locations as necessary.

Manual digitizing provides both technical flexibility and responsiveness. The generation of 3-D anatomical data is not restricted by a fixed market set. This ensures optimal data generation under all conditions including the case of data collection error or oversight.

Data collection

Data collection is a very simple process… two standard video cameras are set up at specific angles to the data collection area. A calibration unit is placed in the area where the patient/athlete will perform the activity and is filmed (using both cameras simultaneously) for approximately 30 seconds (note: when collecting data in a game environment the calibration process is performed prior to the start of the game). The patient/athlete is then filmed (using both cameras simultaneously) performing the activity.

Data Processing

When data arrives at welch-e technologies for processing, it is logged and queued to be processed (you are notified of its arrival and approximate processing queue). All data is processed in the order in which it arrives. A biomechanics technician will then digitize the video to construct the 3-D anatomical model. Once the 3-D model is produced, motion analysis is performed using the appropriate zenolink evaluation application. This motion analysis data is then loaded into the Zenolink database and a report created. You are then notified that the evaluation is ready to be accessed.

What does zenolink tell me?

zenolink measures an individual’s biomechanics during a given activity. Biomechanical parameters include joint range of motion, body segment speed and core posture. However, zenolink goes beyond just making static measurements to mapping complex movement patterns. Using patented and proprietary data visualization techniques, dynamic coordination can be objectively quantified and evaluated – functional performance assessed.

more about Zenolink analysis data

All Zenolink analysis applications are derived from biomechanics research. Measurement parameters are not generic, but instead are specific to the activity of interest. Report data are tailored to provide optimal information about movement patterns and performance.

Physical attributes (ie. strength, flexibility, speed) can be directly related to faulty movement patterns. Faulty movement patterns can be correlated with break downs in performance.

In addition to mapping movement patterns, Zenolink provides numerical assessment of parameters. This information is essential in both making a diagnosis and monitoring the effectiveness of a treatment/training program. Normals (both pattern and numeric) are provided for guidance in assessing data from welch-e technologies’ database of research.

How do I use zenolink data?

Zenolink is a measurement and diagnostic tool only. It does not tell you how to treat a patient or train an athlete. However, like any other measurement / diagnostic tool, zenolink provides invaluable information regarding a patient / athlete’s functional capacity – performance and injury potential.

With Zenolink data, it is possible to pin-point weakness or “break down” in movement patterns specific to a given activity. Even more importantly it is possible to link physical attributes (ie. strength, rom, stability) to weakness in functional movement patterns and outcome parameters. This affords a clinician the ability to create treatment / training programs that have a definite impact on performance for a given activity.

Who uses Zenolink?

Zenolink is used to assess athletes of all levels.  From the weekend warrior to the professional athlete, Zenolink will help you obtain optimal performance.
