Summary: A new study shows that musicians experience pain differently from non-musicians because years of focused training reshape their brains. While induced hand pain typically reduces the size of motor maps and increases reported discomfort in non-musicians, musicians maintained stable motor maps and reported lower pain levels after the same procedure.
The study found a clear relationship between practice time and pain resilience: the more hours a musician had practiced, the more resistant their brain and body were to pain’s effects. These findings point to neuroplastic changes from long-term training that may help protect against some pain-related changes in the brain, with potential implications for future pain therapies.
Key Facts
- Study Group: 40 participants compared — musicians versus non-musicians.
- Brain Maps: Induced pain reduced motor map area in non-musicians but not in musicians.
- Pain Levels: Musicians reported lower pain, especially those with more cumulative practice hours.

Background
Learning to play an instrument produces wide-ranging effects beyond musical skill. A large body of research links musical training to improved fine motor control, language processing, speech, memory, and cognitive reserve. These benefits reflect the brain’s remarkable capacity to reorganize itself — neuroplasticity — in response to extensive, precise practice.
After years of observing musicians who persist through the repetitive strain of practice and performance, researchers asked whether musical training might also alter how people feel and respond to pain. The study discussed here set out to test that possibility directly by experimentally inducing temporary muscle pain and tracking changes in brain maps and self-reported discomfort.
How the study was conducted
To simulate short-term muscle pain safely, researchers injected a small amount of nerve growth factor (NGF) into hand muscles. NGF is a naturally occurring protein that supports nerve health but causes a temporary, movement-sensitive ache when introduced into muscle tissue. The pain is safe, transient, and does not cause tissue damage.
Researchers measured motor cortex activity using transcranial magnetic stimulation (TMS), a noninvasive method that uses magnetic pulses to map how the brain controls specific muscles. Each participant received a TMS-derived hand motor map before the NGF injection, then again two days and eight days after the injection, allowing the team to observe short-term changes in cortical representation alongside reported pain levels.
Main findings: musicians show different brain and pain responses
Even before the pain induction, the musicians in the study had more finely tuned hand representations in the motor cortex. These refined maps correlated with hours of practice: the more cumulative practice time a musician had, the more distinct their cortical hand map appeared.
After NGF-induced hand soreness, non-musicians showed the expected response: a measurable shrinkage of the hand motor map within two days and higher pain reports. Musicians, however, did not exhibit this shrinkage; their motor maps remained stable, and they reported less pain than non-musicians. Importantly, the protective effect scaled with practice history — greater practice hours were associated with lower pain and more stable maps.
These results come from a modest sample of 40 people, so they should be viewed as preliminary. Still, the pattern is consistent and suggests that extensive, long-term sensorimotor training can alter how the brain responds to nociceptive (pain) signals, reducing the typical motor cortex suppression and subjective discomfort that often follow muscle pain.
Why this matters
Pain has an adaptive role: by reducing motor cortex activity and shrinking motor representations, it discourages movement that could worsen an injury. But when these protective responses persist, they can contribute to chronic pain and disability. Understanding why some people show more resilience to these changes could guide new approaches to prevention and rehabilitation.
The findings suggest musical training may offer a model for building resilience in the motor system. If long-term, high-precision practice helps maintain motor representations under pain, similar training principles might be adapted into therapies aimed at preventing or reversing maladaptive brain changes in people with persistent pain.
The research team is continuing to study whether musical training also protects against pain-related changes in attention and cognition, and whether targeted training programs can be developed to promote recovery for people with chronic pain.
For musicians, the study highlights a striking possibility: that daily practice not only hones a skill but can rewire the nervous system in ways that influence how everyday sensations, including pain, are perceived.
Key Questions:
A: Pain commonly reduces activity in the motor cortex and can shrink cortical “body maps,” which is associated with higher pain and reduced motor control over time.
A: Musicians reported less pain after induced muscle soreness, and their finely tuned motor hand maps did not shrink as they did in non-musicians.
A: It suggests that long-term, precise sensorimotor training like musical practice may build resilience to pain by reshaping brain circuits, which could inform new rehabilitation strategies.
