Welcome to Oriems Fit Research Digest
At Oriems Fit, we break down university and hospital studies in plain language.
We do this because science shouldn’t sit locked in journals — it should spark curiosity and help everyday people see what’s possible.
And because we believe in transparency, you’ll always find a link to the original study at the end, so you can fact-check, dive deeper, or collect it yourself.
What the Scientists Wanted to Know
Nerve injuries are brutal. Even with surgery, many patients never get full movement or strength back. The big question for researchers at The Hospital for Sick Children (Toronto, Canada) was simple:
👉 Could a daily dose of Electrical Muscle Stimulation (EMS) help nerves reconnect to muscle more effectively?
The Experiment
Researchers took rats with a surgically repaired tibial nerve (a major leg nerve) and applied a clinically realistic EMS protocol:
-
600 muscle contractions per day
-
1 hour sessions, 5 days a week
-
Continued for up to 3 months
Then they compared recovery in the EMS group vs. the surgery-only group.
The Shocking Numbers
-
After 1 month: EMS muscles had 37 motor units vs. only 22 without EMS.
-
After 2 months: EMS muscles had 104 motor units vs. 57 without EMS.
-
After 3 months: EMS muscles reached 142 motor units — almost identical to normal, uninjured muscles (155).
-
Non-stimulated muscles? They lagged far behind, at just 81 motor units.
-
EMS animals also performed better on skilled walking tests (tapered beam slips reduced significantly from week 6 onward).
The takeaway: EMS didn’t just keep muscles alive — it actively supported better nerve-to-muscle reconnection and faster functional recovery .
Why This Matters
Peripheral nerve injuries affect thousands of people every year, from workplace accidents to sports injuries. Traditional rehab can take months or years, often with incomplete results.
This study shows that a moderate, daily EMS routine could one day become a low-cost, at-home therapy to improve outcomes after nerve repair.

Why We Do This: Oriems Fit Research Digest
We don’t sell fear — we share facts.
Our goal is to take complex university studies and explain them in plain English. Knowledge creates power: power to ask better questions, to see new possibilities, and to use science as a tool for everyday life.
