When HR Dropped a Different Kind of Request on My Desk

In February 2024, our HR manager walked into my office with a folder and a tired look. She said, 'Half the team is asking if we can stock something for period pain. Not aspirin. Something they can use at their desks or take to a meeting.' I am the office administrator for a 220-person diagnostics company—maybe 240 if you count contractors. I manage facilities and wellness purchasing, roughly $140,000 annually across 12 vendors. I report to both operations and finance.

My first thought was simple: buy a heating pad for menstrual pain for each floor. Then I opened the requests. People wanted portable period pain relief, lower back TENS units, a clinical TENS machine, and yes, an EMS pulse massager. I had no idea what half of that meant. I knew I should call occupational health before ordering anything. But I thought, 'It's just a heating pad. What are the odds?' That was the one time it mattered.

I Thought TENS and EMS Were Basically the Same Thing

I started by collecting requests in a shared doc. The language was all over the place. Some employees said 'TENS.' Some said 'EMS.' Some said 'just a massage thing.' I assumed EMS, TENS, and a heating pad were interchangeable ways to relax muscles. From the outside, a lower back TENS unit and an EMS pulse massager look nearly identical—same plastic shell, same sticky pads, same wires. The reality is they are different categories. TENS is generally used for pain modulation. EMS is generally used for muscle contraction. A heating pad is just heat. They are not interchangeable, and the names get blurred by marketing.

I pulled samples from six suppliers. One sent a device labeled a clinical TENS machine. It looked clinical: white box, medical font, a serious manual. Then I read the fine print. The manual called it a wellness device. The vendor was not lying, exactly. The categories are just that blurry. Another supplier offered an EMS pulse massager for about $28. It was cheap, and I almost ordered 50. I even had the purchase requisition open.

Then our occupational health nurse asked one question: 'What are the contraindications?' I did not have an answer. She explained that electrical stimulation devices are not for everyone. Pacemakers, pregnancy, some seizure histories, certain skin conditions—the list is longer than I expected. She also said that if we were going to offer any device, we needed a way to explain the difference between TENS and EMS, not just hand out boxes. I have mixed feelings about that moment. On one hand, I was embarrassed I had not thought of it. On the other, I was grateful it happened before we bought 50 units.

The Pilot That Changed My Checklist

We ran a pilot in March 2024 with 10 employees who had volunteered. We tested three things: a rechargeable heating pad, a TENS unit, and an EMS pulse massager. We did a 15-minute training, not a medical lecture. Just the basics: what each device does, what it does not do, and when to talk to a clinician.

The results surprised me. The heating pad was the most popular. It was simple, discreet, and easy to share. The TENS unit helped some people with lower back pain, but it needed more explanation and more privacy. The EMS pulse massager was more of a relaxation tool. Nobody called it a cure. That was fine with me.

I have mixed feelings about stocking multiple device types. On one hand, simplicity would be nice—one SKU, one vendor, one invoice. On the other hand, one size fits none. We compromised with a primary and backup approach: a main vendor for heating pads and TENS units, and a secondary source for EMS massagers. The backup saved us when one shipment was delayed in April.

During the pilot, I also learned to ask for documentation. Per FTC advertising guidance at ftc.gov, health-related claims must be truthful, not misleading, and substantiated with evidence. As of January 2025, that guidance still applies to claims like 'clinical' or 'pain relief.' So we started requiring manuals, contraindication sheets, warranty terms, cleaning instructions, and battery specs before placing any order.

What We Rolled Out—and What It Cost

By Q2 2024, we stocked 40 rechargeable heating pads, 24 TENS units, and 12 EMS massagers. The total came to around $4,000—maybe $4,300, I would have to check the system. That covered two office locations and a small travel kit for conferences.

We did not call it a medical program. It was not a substitute for clinical judgment. It was a comfort and education program. We put a one-page guide in the break room and on our intranet. It said: heating pads are for heat, TENS is for certain types of pain signals, EMS is for muscle contractions, and if you are unsure, ask your doctor or our occupational health nurse.

About 80 employees used the program in the first quarter. The complaints I used to get—'there is nothing here when I need it'—dropped. I cannot say it reduced pain scores. That would be overreach, and I did not measure it. What I can say is that people felt seen. That matters more than I expected for a purchasing project.

What I Would Tell Another Admin Buyer

If you have ever managed a wellness budget, you know the temptation to buy one SKU and move on. Do not do it. The checklist: confirm TENS or EMS, read the contraindications, test with a pilot. In that order.

People think a higher price means better pain relief. Actually, a higher price can reflect better support, documentation, and warranty—but price alone does not guarantee fit. A $28 EMS pulse massager might be fine for relaxation. It is not automatically a substitute for a clinical TENS machine. And a clinical TENS machine is not automatically right for every employee.

What I mean is that the cheapest option is not just about the sticker price—it is about your time spent answering questions, the risk of an employee using the wrong device, and the potential need to reorder everything after a failed pilot. I would rather spend 10 minutes explaining options than deal with mismatched expectations later.

An informed employee asks better questions and makes faster decisions. That is the lesson I keep coming back to. If you are buying portable period pain relief for a workplace, do not assume EMS, TENS, and heating pads are interchangeable. Ask. Document. Pilot. Then roll out. And if you are not sure, talk to a clinician before you buy.
