SMFR Research

Explore research on self-myofascial release (SMFR), particularly foam rolling, alongside related studies on mobility, exercise and pain. These studies examine SMFR and movement methods; they do not test or validate the IRK tool.

Meta-analysis2019

Foam rolling before and after exercise

A review of 21 studies found that foam rolling before exercise produced small improvements in flexibility, with little effect on strength or jumping performance. After exercise, it helped reduce muscle soreness.

What to keep in mind

This suggests a useful supporting role in warm-up and recovery routines, although the benefits were generally modest. The research focused on exercise-related soreness rather than persistent pain conditions.

Systematic review2022

Regular practice and improved flexibility

A review of 11 studies found that regular foam rolling improved joint range of motion overall, with greater benefits in programmes lasting more than four weeks.

What to keep in mind

Results varied between body regions: improvements were found when rolling the thighs, while calf rolling did not significantly improve ankle mobility. Most participants were young, healthy adults, so the findings may not apply equally to everyone.

Exploring self-massage for persistent neck pain

In a trial involving 58 people with persistent nonspecific neck pain, both supervised foam rolling and Swedish massage were followed by improvements in pain and neck movement over two weeks. Neither treatment clearly outperformed the other.

What to keep in mind

The study had no untreated comparison group and only a short follow-up. It therefore cannot show how much improvement was caused by either treatment or whether the changes lasted.

Randomised trial2023

Self-massage, exercise and posture

A four-week study in young adults found that programmes combining self-massage and stretching, with or without strengthening, improved a measurement of forward-head posture compared with no intervention.

What to keep in mind

Because the techniques were combined, the contribution of self-massage alone remains unclear. The study measured head-and-neck alignment; it did not establish that these changes reduced pain or improved general health.

Systematic review2023

Strength training can also support mobility

A review of 55 studies found that resistance training with external loads improved joint range of motion. Comparisons with stretching showed no significant difference in flexibility gains.

What to keep in mind

This supports including strength training within a mobility programme. Results varied between training methods, so the findings do not mean that every exercise or routine will produce the same improvement.

Cochrane review2021

The role of exercise in persistent lower-back pain

A Cochrane review of 249 trials found moderate-certainty evidence that exercise probably reduces persistent nonspecific lower-back pain compared with no treatment, usual care or placebo.

What to keep in mind

Improvements in everyday function were smaller and did not reach the review's threshold for clinical importance. The review supports exercise as part of pain management, but does not identify one programme that works best for everyone.

Randomised trial2019

Flexibility, strength and balance need different attention

An eight-week trial found that foam rolling improved performance in a flexibility test, while core exercises improved back-muscle endurance. Rolling did not significantly improve balance or jumping performance.

What to keep in mind

Improving flexibility addresses only one part of movement; strength, endurance and balance also deserve attention. The study tested rolling and core training separately, so it could not establish whether combining them provides additional benefits.

Randomised trial2025

Combining self-massage with breathing and movement exercises

A six-week trial involving 40 women with persistent lower-back pain compared stabilisation exercises alone with self-massage followed by the same exercises. Both groups improved, but the combined programme produced greater improvements across pain, balance, flexibility, muscle endurance and everyday function.

What to keep in mind

The combined group received 50-minute sessions compared with 30 minutes for exercise alone, so treatment time may explain some of the difference. The small, women-only sample and lack of longer-term follow-up also limit how widely the findings can be applied.
