What Does the Research Say?
Beyond Exercise: Adjunct Treatments That Add Value
Exercise therapy is the foundation. But what else actually helps when you add it to a strengthening program? Here's what the systematic reviews found.
The Key Question
Multiple systematic reviews have specifically examined whether adjunct treatments provide incremental benefit when added to exercise therapy. The answer varies by modality, and the differences matter for your treatment planning.
Neuromuscular Electrical Stimulation
✓
Strongest evidence for additive benefit. Moderate certainty evidence supports NMES for improving pain and quadriceps strength when combined with exercise.
Kinesiology Taping
✓
Short-term benefits for pain and knee function when added to exercise. Effect sizes modest. Long-term benefits unclear. Reasonable for symptom modulation.
Blood Flow Restriction Training
20-30%
Of one-repetition maximum is all that's needed. Blood flow restriction achieves comparable strength gains to heavy loading while minimizing patellofemoral stress.
Dry Needling
✓
Two separate meta-analyses found significant improvements in pain and function. Common targets: vastus medialis, vastus lateralis, tensor fasciae latae, and gluteals.
Lumbopelvic Manipulation
✓
May provide short-term pain relief when added to standard care. Mechanism likely neurophysiological rather than mechanical. Patient selection criteria still unclear.
Digital Therapeutics
✓
App-based programs combining exercise with cognitive behavioral principles produced significant pain reduction. Particularly valuable for patients with limited clinic access.
3 Takeaways for Your Practice
1
Evidence Hierarchy
Neuromuscular Electrical Stimulation Has the Strongest Adjunct Evidence
If you're adding one modality beyond exercise, NMES has the most consistent evidence for additive benefit. Multiple systematic reviews confirm improved pain and quadriceps strength when NMES is combined with therapeutic exercise.
2
Pain-Limited Patients
Blood Flow Restriction Training Opens Doors for Sensitive Knees
When patients can't tolerate heavy loading, blood flow restriction at 20 to 30 percent of one-repetition maximum can produce comparable strength gains. This keeps progress moving in patients who would otherwise plateau.

Access Solution
Digital Therapeutics Extend Your Reach
For patients with limited access to in-person rehabilitation, app-based programs combining exercise with psychological components offer a viable alternative. They supplement, not replace, clinical care for complex cases.
