Comparing Two Effective Techniques for Tight Hamstrings: MET vs. Percussive Therapy

Hamstring shortness is a frequent musculoskeletal issue, particularly among young adults. While several manual therapy options exist, therapists often debate which technique offers the best results. A study from Turkey compared two widely used methods—Muscle Energy Technique (MET) and Percussive Therapy (PT)—to determine their immediate effects on flexibility and strength.

Study Snapshot

• Participants: 30 college students (aged 18–25) with hamstring shortness
• Groups: Randomly assigned to either MET or PT
• Duration: Each intervention lasted 6 minutes
• Assessments: Sit and Reach Test (flexibility) and hamstring strength (measured with a handheld dynamometer)

What Was Done

• The PT group received a massage gun treatment for 6 minutes, focusing 2 minutes on each hamstring head.
• The MET group underwent 3-minute anterior and 3-minute posterior innominate techniques, which involve active muscle engagement.

Key Results

• Both groups improved significantly in hamstring flexibility and strength after treatment.
• No significant difference was found between the two groups, suggesting both methods are equally effective in the short term.
• MET may provide slightly greater immediate gains due to its active involvement, but PT offers a solid passive alternative.

Clinical Takeaways

• Choose based on client needs: MET may be ideal for clients able to engage actively, while PT is suitable for those preferring or requiring passive treatment.
• Effective for short-term goals: Both techniques are valuable tools for immediate improvement in flexibility and muscle performance.
• Further research is needed: Long-term effects and outcomes in broader populations remain to be explored.

Conclusion

For therapists addressing hamstring shortness, both MET and percussive therapy are valid, effective options. Your decision can be tailored based on patient preference, mobility, and treatment goals—both methods can play a key role in enhancing movement quality and performance.
