Introduction: Examining and Predicting Lower-Extremity Overuse Injuries with Computerized, Video Gait Analysis (01:40)

FREE PREVIEW

Jeffrey Ross introduces the objectives for his discussion on computerized gait analysis for injury prediction.

Force & Pressure (02:57)

Ross explains force and pressure and how those variables can be measured and used as an advanced diagnostic tool. Ross gives an explanation of the technology used to measure force and pressure on the foot.

Sensors and Sensels (02:15)

Ross explains the technical aspects of measuring the force and pressure of a gait and how a sensor mat functions. Ross explains how higher resolutions lead to better data.

Asymmetry (02:25)

Ross talks about how asymmetry is a primary cause of almost all foot and gait disorders. Ross discusses who scans and custom orthotics can fix symmetry problems.

Phases of Gait (02:14)

Ross explains the different phases of gait and goes over some problems that can arise in each phase.

Goal of Orthotic Prescription (05:45)

Ross talks about the prescriptive goal of an orthotic device and what it should accomplish to achieve symmetry of force and pressure.

Symmetry in Limb Length (02:24)

Ross talks about problems of symmetry in limbs and how that effects the feet. Ross points out the ways in which early treatment can benefit pediatric patients.

Symmetry in Force and Acceleration (01:26)

Ross talks about the differences in acceleration and pressure symmetry both with and without orthotics.

MatScan System (02:15)

Ross talks about the capabilities of the Mat Scan system and what data it allows doctors to measure. The mat scan can allow for accurate diagnoses in many disorders, including being used for predicting diabetic ulceration.

Video Gait Analysis (02:07)

Ross shows a look at live data from the mat scan system accompanied by video of the patient performing the gait test. The F scan sensor package is worn inside the shoe.

F Scan Images Part 1 (02:29)

Ross displays a series of F scan images and gives a diagnosis and explanation of the condition being displayed. Examples include: forefoot varus, fibular sesamoiditis, 2nd metatarsalgia, and hallux limitus.

F Scan Images Part 2 (02:13)

Ross displays a series of F scan images and gives a diagnosis and explanation of the condition being displayed. Examples include: hallux rigidus, hallux limitus, tibial sesamoiditis, and capsulitis/bursitis.

F Scan Images Part 3 (02:32)

Ross displays a series of F scan images and gives a diagnosis and explanation of the condition being displayed. Examples include: hammertoe, metatarsus adductus, and posterior tibial tenosynovitis.

F Scan Images Part 4 (02:03)

Ross displays a series of F scan images and gives a diagnosis and explanation of the condition being displayed. Examples include: equinus-abductor hallucis strain, metatarsus adductus, posterior tibial tenosynovitis, fibular sesamoid fracture, achilles tendon repair, genu valgum, diabetic neuropathy, and limb length asymmetry.

F Scan Images Part 5 (02:23)

Ross displays a series of F scan images and gives a diagnosis and explanation of the condition being displayed. Examples include: post ACL repair, insertional calcific achilles tendinosis, post tibial sesamoid fracture, rheumatoid arthritis, achilles tendinitis, and hallux rigidus.

F Scan Images Part 6 (01:40)

Ross displays a series of F scan images and gives a diagnosis and explanation of the condition being displayed. Examples include: plantar fasciitis, achilles tendinitis, and hallux elevatus.

Gait Analysis Demonstration (04:25)

Ross uses a volunteer from the audience to do a live demonstration of gait scanning and diagnosis. Ross uses the scan to accurately guess the foot problems the volunteer experiences.

Gait and Balance Analysis Software (04:46)

Ross talks about the usage of F Scan and the mat scan can be used with balance analysis software to evaluate when athletes are ready for return to play from injury.

Gait Analysis Demonstration 2 (02:31)

Ross displays and diagnoses a second audience volunteer with the gait analysis equipment.
