The study, published in the journal Mindfulness, is a Bayesian multilevel meta-analysis of randomized controlled trials conducted between 2005 and 2025. A team led by Senyao Du of Macao Polytechnic University and Guowen Ai of Hainan Normal University searched six databases, screened more than 4,000 records, and ultimately included 22 randomized controlled trials covering 1,397 participants and 112 separate effect sizes. The trials came from China, India, Thailand, the United States, Iran, and other countries, and tested interventions ranging from Tai Chi and Qigong to yoga and walking meditation against no intervention, health education, or other forms of exercise.

What makes this analysis unusual is its statistical machinery. Rather than relying on traditional frequentist methods, the team used Bayesian multilevel models, which estimate full probability distributions for effect sizes and allow researchers to compute Bayes factors, a measure of how strongly the data support a real effect over no effect. The team also restricted inclusion to three relatively pure laboratory tests of proprioception: joint position reproduction, threshold to detection of passive motion, and the active movement extent discrimination assessment. These vision-occluded paradigms minimize contributions from other senses, making the pooled estimate more interpretable than earlier reviews that lumped together heartbeat detection, tactile tasks, and balance proxies.

The headline result was striking. In the unadjusted model, mindfulness-based interventions improved proprioceptive accuracy with a standardized effect size of Hedges’ g of minus 0.70, where negative values indicate reduced error in proprioceptive judgments. The 95 percent highest density interval ran from minus 0.96 to minus 0.44, and the Bayes factor reached 4,290, which by conventional criteria constitutes overwhelming evidence for a nonzero effect. In plain terms, people who practiced mind-body exercises became measurably better at judging joint angles and detecting passive movements than people who did not.

Subgroup analyses added texture to that headline. Tai Chi showed the largest and most credible effect of any intervention, with g of minus 0.82 and a Bayes factor above 900. Yoga, Qigong, and walking meditation produced negative point estimates but intervals that included zero and Bayes factors at or below one, meaning the evidence for those practices was inconclusive rather than supportive. The most dramatic subgroup was older adults, who showed the greatest improvement of any population at g of minus 0.84 with a Bayes factor of roughly 210,000. College students, teenagers, and athletes showed no credible effects, and for athletes the point estimate actually leaned in the opposite direction, though without statistical significance.

Why would Tai Chi outperform its cousins? The authors point to its distinctive movement signature. Sequences such as Wave Hands Like Clouds and Single Whip demand slow, fluid, multi-joint coordination with continuous transitions between lengthening and shortening muscle contractions, a loading pattern that may efficiently stimulate muscle spindles, Golgi tendon organs, and joint receptors. Tai Chi also fuses movement with breath and concentrated attention, a cognitive-motor integration that engages brain networks for body awareness, movement planning, and executive control. Yoga and Qigong, by contrast, lean more heavily on static postures, and walking meditation involves highly automated, repetitive motion that may offer too little novel proprioceptive challenge to drive adaptive remodeling.

The body-site findings reinforce a mechanical story. The knee and ankle showed the most reliable improvements, with credible effects for ankle dorsiflexion and plantar flexion in particular. These are exactly the joints most loaded during weight-bearing Tai Chi and yoga postures. Dorsiflexion improved more than plantar flexion, plausibly because everyday walking and standing already train the latter, leaving a narrower window for plasticity. Effects were also detectable with the passive motion detection and joint position reproduction tests but not with the more cognitively demanding discrimination task, suggesting the interventions primarily sharpen raw afferent signaling rather than higher-order sensory decision-making.

But here is the catch that keeps this study honest. A significant multilevel Egger test revealed small-study effects, the statistical fingerprint of publication bias, in which smaller, less precise studies tend to report larger effects. When the team applied bias-correction models and averaged across them, the corrected estimate carried a standard error nearly as large as the effect itself, and the resulting confidence interval spanned zero. In the worst case, publication bias could explain all of the observed benefit. The authors also graded the evidence using the GRADE framework and rated the overall certainty for the pooled effect as low, citing serious risk of bias, serious inconsistency, and serious publication bias concerns. Blinding participants to Tai Chi is, after all, impossible.

Still, the practical signals are hard to ignore. Effects grew with intervention duration, with roughly 16 weeks emerging as the point where benefits became most consistent, and the improvement was strongest in older adults, precisely the population where declining proprioception contributes to falls and lost independence. Because mindfulness practices are low-intensity, low-cost, and highly repeatable, they could complement neurorehabilitation programs for people with knee osteoarthritis, chronic ankle instability, or post-stroke deficits, while also delivering well-documented mental health benefits that conventional proprioceptive training cannot. The authors are careful to say these applications should be tested in dedicated large, preregistered, multicenter trials before firm clinical recommendations are made. For now, the message is a measured one: your body’s inner compass may indeed be trainable through the slow, deliberate art of Tai Chi, but science is still calibrating exactly how much the needle moves.

The piece, written by Roberto Tedeschi, an independent researcher based in Bologna, and Sara Di Serio of the Department of Clinical Science and Translational Medicine at the University of Rome Tor Vergata, does not report new experimental data. Instead, it is a conceptual argument, a deliberate provocation aimed at both the mindfulness research community and the rehabilitation sciences. The authors state that no datasets were generated or analysed, and the article carries no ethics approvals, consistent with its nature as a theoretical correspondence. What it offers is a framework: the proposal that the physiotherapist–patient encounter should be understood as a recurring, real-world setting where the psychological and neurobiological ingredients of mindfulness-based care are already in play, whether or not anyone labels them as such.

The argument begins with a paradox. Mindfulness has travelled an extraordinary distance from its origins in contemplative traditions to its current status as a mainstream public health intervention. Since Jon Kabat-Zinn’s landmark 1982 outpatient programme for chronic pain patients, which introduced mindfulness meditation into behavioural medicine, the field has grown into a global enterprise. Recent critical analyses in Mindfulness itself, including Oman’s 2025 agenda for mindfulness in global public health and Sutton’s organisational-psychology perspective on cultivating global health, signal an ambitious push to embed mindfulness at the population level. And yet, the authors contend, this push has concentrated on formal programmes and structured courses, while overlooking the places where embodied awareness is most frequently practised: clinical encounters involving the body itself.

Physiotherapy, the authors argue, is uniquely positioned in this respect. Unlike many medical consultations, physiotherapy is built on sustained physical contact, manual skills, guided movement, and an extended temporal relationship between practitioner and patient. Treatment sessions unfold over weeks or months, giving the therapeutic relationship time to deepen. Scoping reviews of therapeutic alliance in musculoskeletal physiotherapy and occupational therapy, such as the 2017 analysis by Babatunde and colleagues published in BMC Health Services Research, have documented that the quality of this alliance is not a peripheral nicety but a core component of practice that shapes engagement, adherence, and outcomes. In other words, the relational dimension of physiotherapy is not an optional extra layered onto exercise prescription; it is woven into the delivery of care itself.

The concept at the heart of the correspondence is therapeutic presence, a construct developed most prominently by Geller and Greenberg in their 2012 book Therapeutic Presence: A Mindful Approach to Effective Therapy, and operationalised in a 2010 measurement study by Geller, Greenberg, and Watson in Psychotherapy Research. Therapeutic presence describes a clinician’s state of being fully attentive, receptive, and embodied in the encounter with a patient—listening not only with the ears but with the whole nervous system. Presence, in this account, is not a vague bedside manner but a trainable, mindful capacity with measurable correlates in both therapist and client perception. The authors of the correspondence propose that physiotherapists, whose work demands continuous attention to bodily cues, are natural practitioners of presence, even if the term never appears in their training curriculum.

Why should this matter for outcomes? One strand of evidence comes from the science of contextual factors. In 2023, an international group led by Cook and colleagues, publishing in Frontiers in Psychology, reached a consensus definition for contextual factors: the elements of the therapeutic encounter—expectations, the clinician’s manner, the setting, the ritual of treatment—that modulate outcomes independently of the specific technique delivered. This line of research, closely tied to placebo and nocebo science, has made it increasingly difficult to dismiss the relational and cognitive environment of care as noise. In physiotherapy specifically, systematic reviews of attentional focus instructions, including the 2018 review by Piccoli and colleagues in the Journal of Functional Morphology and Kinesiology, show that the way a clinician directs a patient’s attention changes motor learning and performance in both central nervous system and musculoskeletal disorders. Attention, in other words, is a clinical variable, and a mindful clinician is one who manages it deliberately.

A second strand comes from pain neuroscience. Bushnell, Čeko, and Low’s influential 2013 review in Nature Reviews Neuroscience mapped how cognitive and emotional processes modulate pain and how these regulatory systems become disrupted in chronic pain. Pain is not a simple readout of tissue damage; it is constructed through an interaction of sensory input, attention, expectation, and affect. This is precisely why the mental state of the clinician may matter. A distracted, hurried practitioner may inadvertently amplify threat appraisals, while a present, calm one may foster the sense of safety that allows descending pain-modulatory systems to work in the patient’s favour. The correspondence frames the physiotherapy room as a place where these mechanisms can be observed, refined, and taught—not as abstract theory but as lived clinical practice.

The authors also draw on the phenomenology of body awareness. Mehling and colleagues’ 2011 inquiry into body awareness as the common ground of mind-body therapies, published in Philosophy, Ethics, and Humanities in Medicine, positioned interoception—the perception of internal bodily signals—as the shared substrate of practices ranging from meditation to massage. Price and Hooven’s 2018 work on interoceptive awareness skills for emotion regulation, through the mindful awareness in body-oriented therapy approach, translated that substrate into teachable clinical skills. More recently, Parma and colleagues’ 2024 overview in Brain Sciences charted progress on bodily awareness and interoception in neurorehabilitation research. Clinical perspectives on the notion of presence, gathered by Malet, Bioy, and Santarpia in Frontiers in Psychology in 2022, add a cross-disciplinary frame. Seen through this converging literature, the physiotherapist’s hands are not merely applying technique; they are participating in a bidirectional channel of interoceptive and proprioceptive information, one that mindfulness research has rarely examined in situ.

The public health implications of the argument are what give it its edge. If mindfulness is to fulfil the population-level ambitions set out in recent global health agendas, the authors suggest, it cannot rely solely on scaling formal eight-week courses, which carry costs, access barriers, and adherence challenges. Embedding mindful presence into existing, universally used services—rehabilitation being one of the most widely delivered—offers a complementary route. Every physiotherapy encounter becomes, in their phrase, a natural laboratory: a setting where presence, attention, touch, and body awareness interact without the artificiality of a lab-based attention task or a self-report questionnaire administered in isolation. Training physiotherapists explicitly in mindfulness and presence, the correspondence implies, could turn an enormous segment of routine healthcare into an informal delivery channel for skills already known to support emotion regulation, pain modulation, and motor learning.

The correspondence is careful in its limits. It proposes no trials, reports no measurements, and acknowledges its status as a conceptual intervention rather than an empirical one. But that is part of its strategic function. By naming the physiotherapist–patient encounter as a natural laboratory, the authors issue an invitation: to design studies that measure presence in rehabilitation settings, to test whether mindfulness training for physiotherapists alters patient outcomes, and to integrate the constructs of psychotherapy research with the biomechanics of manual therapy. If the invitation is taken up, the humble treatment table—arguably one of the most intimate interfaces in modern medicine—could become one of the most informative sites in the science of mind-body health. The next phase belongs to researchers willing to walk into the clinic and watch closely.

Interoception refers to the sensing of internal bodily states: the heartbeat pounding in the chest, the tightness of a full stomach, the heaviness of breath during anxiety. Far from being a passive background process, interoception is now understood as a foundation of emotional experience. Prominent neuroscientific theories propose that emotions are, at their core, the brain’s interpretations of bodily signals, and that the brain continually generates predictions about the body’s internal condition, updating them against incoming sensory evidence. When this predictive machinery misfires, the reasoning goes, emotional life can become distorted in ways that resemble psychiatric symptoms.

Borderline personality disorder, characterized by emotion dysregulation, impulsivity, chronic feelings of emptiness and an unstable self-image, has long been hypothesized to involve altered interoception. Clinical observations lend intuitive support: many patients describe feeling detached from their bodies, unsure whether they are hungry or full, numb or distressed. Previous studies, however, have produced inconsistent results, with some reporting impaired heartbeat perception in patients and others finding no difference from healthy controls. The new research tackles this inconsistency by treating interoception not as a single faculty but as a set of distinct dimensions that can be selectively affected.

This dimensional approach is technically important. Contemporary interoception research distinguishes between several separable components. Interoceptive accuracy measures how well a person can actually detect internal signals, most commonly the heartbeat, in tasks such as counting heartbeats without taking a pulse. Interoceptive sensibility captures a person’s self-reported beliefs about their bodily awareness, typically assessed with questionnaires. Interoceptive awareness reflects the metacognitive match between the two—whether someone’s confidence in their bodily perceptions corresponds to their actual performance. A person might be poor at detecting their heartbeat yet entirely confident, or accurate yet full of doubt, and these profiles carry different psychological implications.

Applying this framework, the researchers assessed a group of individuals diagnosed with borderline personality disorder alongside matched healthy comparison participants, using a battery of behavioral tasks, self-report instruments and metacognitive analyses. The results revealed a pattern of impairment that was selective rather than global. Patients did not show a uniform deficit across all facets of interoception. Instead, particular components—most notably certain aspects of cardiac signal detection and the metacognitive calibration of bodily confidence—were disrupted, while other facets remained relatively intact. This selectivity, the authors argue, may explain why earlier studies seemed to contradict one another: depending on which dimension a study happened to measure, it could find impairment or normal performance in the same population.

The specificity of the deficit is more than a methodological footnote. Different interoceptive channels and dimensions are thought to map onto different aspects of emotional and self-related processing. Cardiac interoception, in particular, has been linked to the experience of emotion intensity and to the brain’s ability to attribute arousal to its proper source. Difficulties in accurately reading cardiac signals, or in knowing when one’s bodily judgments can be trusted, could plausibly contribute to the emotional storms and unstable self-experience characteristic of the disorder. A person whose internal alarm signals are garbled may misread minor stress as catastrophe, or fail to register escalating distress until it erupts into impulsive action.

Crucially, the study did not stop at diagnosis. Because a subset of patients was assessed in relation to clinical treatment, the researchers were able to ask whether interoceptive function changes as symptoms improve. The findings suggest that treatment is associated with measurable shifts in interoceptive performance, hinting that the body’s signaling systems are not fixed features of the disorder but dynamic processes that can be reshaped. This has immediate translational appeal. If specific interoceptive impairments track symptom severity or recovery, they could serve as objective biomarkers—measurable indicators that complement the self-reports and clinical interviews on which psychiatric diagnosis currently depends.

The implications extend to therapy design as well. Existing frontline treatments for borderline personality disorder, including dialectical behavior therapy and mentalization-based approaches, already incorporate attention to bodily states, for example through mindfulness exercises that direct patients toward physical sensations. The new results suggest that such components may be more than auxiliary techniques; they may directly target mechanisms central to the illness. More speculatively, interoception-focused interventions—heartbeat tracking training, biofeedback, body-oriented psychotherapies—could be tailored to the specific deficits a patient exhibits, in the same way that rehabilitation after brain injury is matched to a patient’s particular cognitive profile.

Neuroimaging work by other groups provides a plausible biological substrate for these findings. Brain regions including the anterior insula, the posterior insula and the anterior cingulate cortex form a network that integrates visceral signals with cognitive and emotional context, and structural and functional anomalies in this network have been reported in borderline personality disorder. The selective pattern observed behaviorally in the new study is consistent with the idea that distinct nodes of this interoceptive network compute distinct things—the insula mapping bodily state, cingulate regions linking it to motivation and distress—and that damage or dysregulation at particular nodes produces particular symptoms rather than a general bodily numbness.

The researchers are careful to note the limitations inherent in this line of work. Cardiac tasks measure only one interoceptive channel among many, and heartbeat detection performance is influenced by factors ranging from body mass index to task strategy. Questionnaire-based sensibility measures can diverge from actual performance in ways that are themselves informative but difficult to interpret. Larger longitudinal cohorts will be needed to determine whether interoceptive deficits precede the onset of borderline symptoms, whether they predict treatment response, and whether deliberately training interoception produces durable clinical gains. Still, the study marks a conceptual shift: it reframes a disorder often described in purely psychological terms as one that involves measurable, treatable alterations in how the brain reads the body, opening a research agenda in which psychiatry and systems neuroscience converge on the question of what it feels like, at the most fundamental level, to be inside one’s own skin.
