Dartfish Biomechanical Analysis

What is Dartfish Biomechanical Analysis?

The quick answer is Dartfish Biomechanical Analysis is software that aids in analysis of different sport specific movement patterns. The team at the Jacksonville Orthopaedic Institute and the JOI Sports Center utilizes Dartfish for biomechanical assessments.  This is to bridge the gap between kinesthetic and visual learning processes. Dartfish develops and offers cutting-edge video solutions that empower its users to capture, analyze, and share video content.

Capturing Video with Dartfish Biomechanical Analysis

Dartfish allows our team to capture your movements with ease. We can film it live with a camera or a phone for on analysis. In addition, Dartfish can be utilized after a game or practice for training and feedback. 

Analyze Video

Dartfish provides a technical motion analysis and tactical game analysis. This allows our athletes and patients to improve quickly by looking at areas of improvement.  You can quickly display deficits and add reviews. These can be achieved on a mobile phone, personal computer, or tablet.  The software lets our team personalize each video specific to an athlete’s needs.  We have specific templates for each sport based on actual measurements of joint angles and biomechanics. 

Share Dartfish Biomechanical Analysis

Video analysis done with Dartfish software can be shared with patients, athletes, and coaches to allow for continued improvements.  If the athlete moves on to college, just send us a video and we can compare it to your previous video.   

Cycling or Biking 

The Dartfish software allows the team at JOI to measure critical angles throughout an individuals pedaling stroke and conduct a biomechanical assessment. The software can correctly determine joint angles and provide instant feedback to correct deficits. The ultimate goal is to improve posture while cycling and engage in proper mechanics.

The team at JOI utilizes Dartfish to assess a patients run and gait. Patients can be assessed whether they are advanced or beginning runners. The gait cycle begins when the foot touches the ground and ends when that same foot touches the ground again to begin the next step. Analysis of the gait during running and walking will vary because the process of running involves a period of time where there will be no contact with the ground, unlike walking which always has contact with the ground. JOI trained staff can analyze a patients’ gait while running with shoes or going barefoot. With the use of a camera and Dartfish, our team will analyze a patient’s gait from both a front and side angle. In addition to the Dartfish assessment, patients can also receive a FootMaxx assessment.

The staff at JOI can use Dartfish software to analyze a patient or athlete’s golf swing mechanics. The purpose of this is to assess any biomechanical deficits and reduce the risk of injury by addressing any issues. JOI can also provide exercises for individuals to improve their game by reducing their risk of injury. Our staff can provide this information to both the patient and their professional, who can assist in perfecting their swing and improving technique.

With the use of Dartfish, JOI staff can evaluate tennis movements and are able to provide feedback to reduce the risk of injury. Dartfish’s use of video allows an individual to see how their Forehand, Backhand, and Serve compare to a professional’s.

Throwing for Baseball and Softball

Dartfish technologies allow JOI staff to conduct a video analysis of a thrower’s mechanics and evaluate their deficiencies. JOI staff can assess flexibility, strength or mechanical deficiencies that can lead to a higher risk rate of injury in young and professional athletes. By recording the athlete at three angles, frontal, side, and rear, our staff can address concerns that may predispose an athlete to injury.  To read more about the proper technique of throwing, please read this article definition of baseball biomechanics injury
