Measurement Techniques in Myography

The video tutorial demonstrates how to perform measurements on a myogram using a software tool. It covers loading a baseline file, adjusting the display settings, selecting myograms for analysis, and measuring various phases such as latency, contractile, and relaxation. The tutorial also explains how to measure amplitude using the peak-to-peak method and provides guidance on repeating these measurements for additional myograms.

What is the first step when loading a file for measurement?

• Click on 'Edit' and then 'Open'

• Click on 'File' and then 'Open'

• Click on 'Tools' and then 'Open'

• Click on 'View' and then 'Open'

Which menu option is used to autoscale the horizontal display?

• Tools

• Display

• Edit

• View

What tool is used to zoom in on a myogram?

• Ruler tool

• Magnifying glass icon

• Hand tool

• Arrow tool

How is the latency phase measured in a myogram?

• From the start to the peak

• From the peak to the end

• From the start to the change in slope

• From the end to the start

What is the delta T value for the latency phase in the example?

• 0.084 seconds

• 0.020 seconds

• 0.251 seconds

• 0.421 seconds

What does the contractile phase measure?

• From the peak to the end

• From the end of latency to the peak

• From the start to the end

• From the start to the peak

What factors can affect the relaxation phase measurement?

• The color of the myogram

• The tightness of the string

• The width of the myogram

• The length of the myogram

How is amplitude measured in a myogram?

• Using the scroll triangle

• Using the peak to peak measurement

• Using the I beam tool

• Using the magnifying glass

What is the force measurement unit used in the example?

• Kilograms

• Grams

• Newtons

• Pounds

How can the force measurement be converted to Newtons?

• Divide by 9.82 m/s²

• Subtract 9.82 m/s²

• Multiply by 9.82 m/s²

• Add 9.82 m/s²
