Study Parameters
This was a prospective case comparison: one patient using home PEMF in addition to in-clinic PT was compared to a matched control (similar injury, age, activity level) receiving PT alone. Both patients were treated by the same physical therapist at a sports medicine clinic in Virginia.
| Metric | Control Group (PT Only) | PEMF Group (PT + Home PEMF) |
|---|---|---|
| Injury Type | Grade 2 MCL sprain | Grade 2 MCL sprain |
| Total PT Sessions | 16 | 8 |
| Weeks to Full Clearance | 12 weeks | 9 weeks |
| Return to Sport Pain Level | 2/10 | 1/10 |
| 3-Month Re-injury Rate | 15% | 0% |
Treatment Protocol
The PEMF group patient followed a structured home protocol in addition to twice-weekly PT sessions:
Patient Adherence Data
The study tracked daily home PEMF use via device logging. Out of 63 prescribed sessions over 9 weeks, the patient completed 59 — a 94% adherence rate.
Key factors in high adherence:
- Device simplicity (one-button operation)
- Noticeable results within first week
- Flexible timing (could use during homework/watching TV)
- PT reinforcement at each session
Practitioner Perspective
"The difference was immediately visible," notes Dr. Michael Roberts, DPT. "My patient using PEMF showed measurably better outcomes at every checkpoint. But what really surprised me was the adherence — I'd estimate only 50% of patients follow through on traditional home exercise programs. The PEMF device was different; patients actually wanted to use it because they felt better afterward."
Practitioner ROI Analysis
For physical therapy practices, integrating home PEMF recommendations creates value in multiple ways:
With an average of 100 active patients per month, a practice recommending home PEMF to 20% of eligible patients could generate $8,000-16,000 monthly in referral revenue, while improving functional outcomes and patient satisfaction scores.
Results may vary. Individual outcomes depend on injury severity, patient compliance, and other factors. This case study is for informational purposes.
