Are Peak Moment and Peak Torque Equivalents in Biodex Dynamometry Measurements?

TL;DR Summary

Peak Moment vs. Peak Torque in Knee Extension

Apologies if this is in the wrong section as it isn't particularly medical in nature despite it being about the body.

I am currently conducting a rapid review with outcomes of knee muscle strength. This is measured by biodex dynamometry, which assesses numerous values including Peak moment (Nm). My issue is that another study has also used the same equipment but reported values of (Nm) as peak torque which makes sense as the movement in question is rotational (Think bent knee -> straight knee, the peak force produced by this movement). My question is whether these two values are the same but have been reported differently or if it is a completely different value with the same unit of measurement.

Thanks!

Welcome to PF.
What an engineer calls a moment, a physicist calls a torque.
The least confusing term would probably be torque.

In physics, a moment is an expression involving the product of a distance and physical quantity

So a moment can involve any physical quantity.

In physics and mechanics, torque is the rotational equivalent of linear force.

A torque is a moment that specifically involves a force.

And there is also a couple, which is a special case of a torque:

In mechanics, a couple is a system of forces with a resultant (a.k.a.net or sum) moment but no resultant force.

So in the following figure, the top arrangement is a force producing a torque. But the bottom arrangement is a resultant force F (not producing a torque), and two forces C producing a couple. They both have the same effect on the system.

Have both values the same magnitude in Newtons-meter?
