The Story Behind RGM
The Ronnie Gardiner Method was created by Ronnie Gardiner, an American-born jazz drummer who played with greats such as Dizzy Gillespie, Gerry Mulligan, and Benny Carter.
Ronnie Gardiner is born in the United States.
He moves to Sweden and becomes an important figure in Swedish jazz.
After a personal tragedy in 1980, he spends about 13 years developing RGM with input from neuroscience experts.
He receives the Swedish Mensa Award, and his life story is told in the Swedish documentary En ovanlig livsresa (An Unusual Life Journey).
RGM comes to the USA, and Jill Stowell becomes the first certified RGM trainer in America.
Today RGM is practiced in rehabilitation and community programs across Europe, including Sweden and the Netherlands, and in New Zealand, and it has been studied at Swedish universities including Gothenburg and Linköping.
What Does the Research Say?
RGM has been studied for more than a decade, mostly by researchers in Sweden. Here is what published studies have found so far.
Stroke Recovery
In a randomized controlled trial of 123 adults in the late phase of stroke recovery, people in a rhythm-and-music program based on RGM reported greater recovery than a control group, and the gains were still there six months later.
Parkinson's Disease
In a randomized controlled trial of 46 people with Parkinson's disease, 12 weeks of group RGM improved quality of life and confidence about avoiding falls compared with a control group. Participants also described better mood and alertness. These gains faded within three months after the program ended.
An Early Parkinson's Pilot
In a first pilot study of 18 people with Parkinson's disease, those who did RGM improved more in mobility, cognition, and quality of life than the comparison group. There were no adverse events, and participants stuck with the program.
What Participants Say
In interviews, stroke survivors said the challenging RGM patterns helped them feel connected to their bodies again and brought more joy and energy. They named the music, the group, the challenge, and a skilled instructor as what made it work.
The Research So Far
A review of 23 studies found early evidence of benefits for stroke rehabilitation and mixed results in other groups. Participants consistently describe RGM as motivating and enjoyable, and the authors call for more controlled trials.
New Research Underway
A new multicenter randomized controlled trial at four sites in Sweden is testing 12 weeks of RGM for balance, walking, thinking skills, and quality of life in 84 adults living with stroke.
RGM Comes to the USA
After more than 30 years of use in Sweden and Europe, the Ronnie Gardiner Method came to the USA in 2023, and Jill Stowell, founder of Stowell Learning Center, became the first certified RGM trainer in America.
We are so honored to offer RGM groups at Stowell Learning Center in Chino and at Hillcrest Senior Living in La Verne. The training supports all levels of our Learning Skills Continuum and offers an opportunity to provide group experiences for increasing executive function, social skills, regulation, and cognitive enhancement.

Yes. RGM has been used for more than 30 years and studied for more than a decade, mostly at Swedish universities. A randomized controlled trial in late-phase stroke recovery found greater perceived recovery that lasted six months, and trials in Parkinson's disease found gains in quality of life, mobility, and fall confidence. A 2024 review calls the evidence early but promising, especially for stroke, and a larger multicenter trial is now underway in Sweden.
