I have no doubt this is true and has been for me at every place I worked since I got into this field in the 90s. Except when I did an on-site contract for a government department. They would not allow this. I had to make a spreadsheet to show the stakeholder that the computer they had provided was costing them $x a day for me to just sit there watching a build. They did replace the computer.
At one place I worked at years ago, I think ergonomics was the magic keyword to unlock a nice work environment.
I know this because one of my coworkers went from a shitty pc104 keyboard to a dedicated keyboard tray an expensive kinesis keyboard and a trackball mouse.
I suspect there must have been RSI problems they had to pay out on.

This might be surprising, but you can bring your own keyboard and mouse to the office. Perhaps even get your employer to pay for them.
I've done this with every office I ever worked at. Dear employer I love you but my hands are my bread-and-butter and they trump your office standards. My hands, my peripherals. You're welcome to pitch in. If you have a problem with me using custom gear, bye.
