Key Takeaway
5 minutes of percussive massage with Hypervolt increased ankle ROM without impairing muscle performance
Summary
This controlled study examined whether percussive massage treatment with a Hypervolt device could improve range of motion and muscle performance in the plantar flexor muscles.
Methods
- Controlled crossover design with 16 healthy males
- 5-minute percussion treatment of calf muscles with Hypervolt
- Compared to control condition (sitting only)
- Measured dorsiflexion ROM and maximum voluntary contraction torque
Key Results
- Significant increase in ankle dorsiflexion ROM after treatment
- No negative effect on maximum voluntary contraction torque
- Benefits present immediately post-treatment
- ROM improvements comparable to foam rolling effects

Limitations
- Small sample size (n=16)
- Only tested calf muscles
- Acute effects only (no long-term follow-up)
- Single treatment session
