As we approach our 15th year of serving the Kansas City area, we would like to thank medical providers and patients for  entrusting us and for giving us the opportunity to help improve movement, function, and quality of life.  As always during our one-on-one  sessions, Summit Strength’s therapists provide high level movement and mechanical analysis and treatments that are guided by evidence and clinical experience in order to meet the needs of our orthopedic, neurological, and pediatric clients.


In order to stay at the front of relevant and evidence-based therapy, we have recently obtained certification to provide blood flow restriction therapy (BFR). Scientific literature is showing that BFR is a powerful clinical tool that can be used to help our patients reach their goals more quickly. In recent years, physical therapists including those involved with the US Department of Defense, the National Basketball Association, Major League Baseball, the National Football League, and collegiate athletic programs have begun integrating BFR with outstanding results; however, the concept of BFR is not new. It has appeared in physiological journals for decades, and current US Department of Defense BFR trials are receiving approximately $6.1 million in funding, although there are many non-Department of Defense related trials being conducted presently.

  • FDA listed device for clinical use
  • Built in Doppler for safety
  • Results in increased collagen strength (Boessen 2014)
  • Increases protein synthesis w/ no markers present for muscle damage(Fry 2010) (Gundermann 2014) (Kumar 2009)
  • Increases VO2max (Abe 2010)
  • Reduction in myostatin levels leads to inhibition/reversal of fibrosis(Bo 2012) (Santos 2014)
  • Increased tPA antigen—no signs of increased clotting factors (Clark 2011)
  • No increase in arterial stiffness (Loenneke 2011)


We have begun to use BFR on several selected patients, and we are seeing very exciting, positive results.

We believe the scientific evidence may support this modality more than most of the passive modalities currently being used. Please call if you have questions, and we encourage you to stop by to observe the process!
