OTP

Read on for my review of this awesome product, and why I asked to be an affiliate of this company.

I am a generalist OT (NOT a hand therapist!). I’ve worked in a wide variety of settings, from the ICU to a residential mental health facility. And while I’ve never specialized in hands, the reality is that occupational therapists get a lot of hand-related questions—not just from patients, but also friends and family.

So, when I saw that our hand therapy lead here at OT Potential mentioned her use of HawkGrips on our tennis elbow, golfer’s elbow, and carpal tunnel clinical decision support pages, I was intrigued.

Instrument assisted soft tissue mobilization (IASTM) has solid evidence behind it (see references below). While hand therapists can pursue advanced certifications in the nuances of IASTM, the reality is that it is a safe and cost-effective intervention for someone like me to try on low-level, early stage injuries.

So, after doing my research, I reached out to HawkGrips to see if I could become an affiliate.

I also purchased my own multi-tool with emollient cream, and here’s what I like about it:

• Most importantly: You can actually see the increased blood flow happening. This is the key selling point for me. Our nerves and tendons need good blood flow around them to stimulate healing, and when it is actually VISIBLE, it’s super satisfying for me and the patient.

• HawkGrips provides plenty of support videos for generalists like me!

• This tool is built to last. Like, someday my kids will inherit it.

All of that is to say, I can definitely appreciate why:

1. These are the go-to tools for hand therapists (and a major nice-to-have for generalist OTs like myself), and

2. It’s worthwhile for athletes or people with regular soft tissue injuries to purchase their own!

If you decide to grab some of these tools for yourself, use our promo code “OTP” today! 

Reminder: OT Potential is an affiliate of HawkGrips, and we use our cut of each sale to create more educational resources for occupational therapy professionals.

If you have any questions, please reach out to us!
