Blood flow restriction doubled grip strength gains in tennis elbow rehab
In short
Fifty-two patients with lateral epicondylitis (tennis elbow) had 12 physical therapy sessions over 6 weeks, and half also did low-load blood flow restriction (BFR) training. Grip strength rose by an average of 17.5 lb with standard therapy and 35.5 lb with BFR added, and arm function scores also favored BFR. Pain scores, however, improved by the same amount in both groups.
Lateral elbow pain is common in people who grip hard all week: deadlifts, rows, curls. In a single-blind randomized trial, adding low-load blood flow restriction to standard physical therapy roughly doubled the gain in grip strength.
How was the trial set up?
- Participants: 52 patients with lateral epicondylitis, randomized into two groups.
- Duration: both groups had 12 sessions over 6 weeks.
- Difference: one group got standard physical therapy only; the other added low-load BFR training.
- Outcomes: grip strength on a hand-held dynamometer (primary), the PRTEE tennis elbow questionnaire, pain at rest and during activity, and satisfaction.
What changed with BFR added?
Both groups improved in grip, function and pain. The gap was in grip strength: 17.5 lb on average with standard therapy versus 35.5 lb with BFR, and post-treatment grip was clearly higher in the BFR group. The PRTEE function score also favored BFR. Pain scores and treatment satisfaction did not differ between groups.
Why does this matter for lifters?
Tennis elbow makes heavy gripping painful, and grip that fades during that time is the first thing to fail on deadlifts and rows. Because BFR builds strength with light loads, it can fill that gap. The basics are covered in blood flow restriction training explained. When you start logging deadlifts again during rehab, note in fairlift which sets used straps and which were raw so the recovery trend is easy to read.
These are short-term results measured right after treatment. BFR can be risky with the wrong cuff pressure, so for rehab, do it under a physical therapist's guidance.
Frequently asked questions
Does blood flow restriction training help tennis elbow?
In a randomized trial of 52 patients, adding low-load BFR to 6 weeks of physical therapy raised grip strength by about 35.5 lb on average, double the 17.5 lb gain with standard therapy. Arm function scores were also better.
Does BFR reduce tennis elbow pain faster?
No. In this trial, pain scores improved by the same amount with standard therapy and with BFR added. The differences were in grip strength and function.
How long was the treatment?
Both groups had 12 sessions over 6 weeks, or two per week. Results were measured at the end of treatment.
Can I do BFR training on my own?
For rehab, it is safer under professional guidance. The wrong cuff pressure or duration can stress nerves and blood vessels.
