Summary
The orthogonal kinesiotaping test (OKT) offers a simple, noninvasive method to diagnose dynamic common peroneal nerve (CPN) compression. This test provides immediate, temporary relief, aiding in identifying positional nerve entrapment.
Area of Science:
- Neurology
- Orthopedics
- Sports Medicine
Background:
- Dynamic compression of the common peroneal nerve (CPN) at the knee is often underdiagnosed.
- Static diagnostic methods like EMG and MRI may miss positional nerve entrapment.
Purpose of the Study:
- To evaluate the orthogonal kinesiotaping test (OKT) for diagnosing dynamic CPN compression.
- To assess OKT's efficacy as a potential fourth clinical sign in the Hagert diagnostic framework.
Main Methods:
- A prospective monocentric study involving 111 patients (124 knees) with suspected dynamic CPN compression.
- Inclusion criteria: Hagert triad (fibular tunnel tenderness, positional weakness, positive Scratch Collapse Test).
- OKT involved applying kinesitape perpendicular to the CPN at the fibular neck with 20% tension.
Main Results:
- Immediate strength improvement (≥1 MRC grade) in 120/124 knees.
- Pain reduction in 100% of patients and improved fatigability in 96.4%.
- Functional improvements were immediate and reversible upon tape removal.
Conclusions:
- OKT is a simple, reproducible, and noninvasive diagnostic tool for dynamic CPN compression.
- The test demonstrates immediate and reversible functional improvement, supporting its role in diagnosing mechanical nerve entrapment.
- OKT may be valuable in clinical settings and potentially applicable to other dynamic nerve entrapments.
