Both dry needling and ultrasound interventions have been shown to induce significant neurophysiological changes in the brain, as evidenced by fMRI studies ().
These techniques appear to create alterations in pain perception and processing, potentially leading to chronic pain conditions rather than resolving them. For instance, dry needling has been shown to reduce the excitability of the central nervous system by modulating brainstem areas and reducing dorsal horn neuron activity, which can affect pain pathways ().
Ultrasound therapy has also been linked to changes in brain activity, particularly in areas associated with pain processing. Studies suggest that ultrasound can enhance tissue healing and reduce inflammation, but the neurophysiological mechanisms remain less understood ().
The emerging data compels a reconsideration of these methods' safety and efficacy, advocating for more ethical and non-invasive alternatives. The long-term impacts on nervous system health remain a critical area for further research, particularly regarding the potential for these interventions to lead to chronic pain conditions rather than alleviating them.
