How do you know a workplace exoskeleton fits the person wearing it?
I'd love for someone to finish a shift with less strain because a wearable support took some of the load. I'd hate for them to be told to get used to a chest pad that hurts. NIOSH's December 2020 discussion of occupational exoskeletons makes a useful distinction: offering several sizes doesn't settle fit. Shoulder width, torso length and hip width matter together. It specifically notes that chest pads on back-support devices may be uncomfortable for women, and that poor fit can produce awkward working postures. These are existing research concerns, not a test of a current product. Occupational exoskeletons include both powered devices and passive supports; neither label tells you whether one fits. For a workplace trial, I'd want the worker and a qualified ergonomics or safety specialist to assess the actual task together, following the device's instructions. A comfortable standing pose wouldn't persuade me that reaching and bending will feel right. The worker needs a way to report pressure or restricted movement and stop the trial without being treated as the problem. That's the trial I'd ask for, not a procedure NIOSH tested in this article. If a device fits some colleagues but not others, what alternative removes the strain for the people it leaves out? I'd want that answered before a team calls the rollout a success.

I'd put changing the job on the purchasing shortlist, not reserve it for people the suit doesn't fit. Ask the worker and ergonomics specialist to compare the wearable with changes to the load, working height or handling equipment. Those are options to assess for the actual task, not fixes I'm prescribing from here. Otherwise the budget can be spent before anyone asks whether people needed to wear another thing at all. A well-fitted device might still be the best choice. It should have to compete with a less awkward job.
Can the wearer take it off for a toilet break without waiting for someone who knows the straps? I'd include removal and putting it back on in a supervised trial, following the manufacturer's instructions, and allow time for both within the shift. That's a practical question I'd add, not something this NIOSH article tested. A support that feels comfortable while lifting could still make someone delay a break because getting out of it is a production. Workers shouldn't have to explain a private need just to get help removing their equipment.
Keep people who stop wearing it in the trial results. If the end-of-week comfort score comes only from those still using the support, the people it hurt may have disappeared from the average. I'd record how many started, how many stopped and their reasons, alongside the remaining wearers' reports. That's a measurement choice I'd propose, not a result from this NIOSH article. A device that helps some workers could still be worth offering; that doesn't justify making it standard equipment for everyone.
I'd also keep the outcome's name attached to any percentage in that trial report. The NIOSH article cites a 10–44% reduction in back muscle activity during laboratory handling tasks. That isn't a 10–44% reduction in back injuries. The same article notes possible new risks, including chest pressure. Those older lab findings are a reason to investigate a support, not a promise about a particular worker's next year. If a purchasing presentation turns ‘less muscle activity’ into ‘fewer injuries’, ask for the study that measured injuries. A worker reporting pain shouldn't have to argue against a safety claim the cited evidence never established.
