Modulation of Pain Perception Through Identifying Emotionally with Music Feedback During Physical Exercise for Patients with Chronic Pain: A Randomized Trial.
Abstract
The emotional modulation of pain can be achieved through interventions in the form of music, which may therefore be valuable in regulating emotions and perceived pain during physical activity. The present study aimed to investigate the effects of music feedback during physical exercise on chronic pain patients' emotional states, motivation, and pain levels during an acute clinic stay. A crossover design was used to test the effects of music feedback during an ergometer training (active condition) vs. music listening during an ergometer training (passive condition) on 43 patients with different chronic pain conditions during their acute clinical stay. An acute clinic specializing in pain medicine. Patients were recruited by clinical staff and randomly assigned to perform both conditions in different orders. The music was selected from 4 genres, and the same songs were used in the training sessions for both types of conditions. The results showed that patients' motivation to exercise was stronger during the active condition than during the passive condition, as measured by active engagement during the training interval (t(39) = 3.013, P = 0.006; 95% CI: 0.0104; .0529). Those findings matched with patients' individual ratings of their motivation. For both conditions, anxiety levels decreased significantly from baseline (active condition: Z = -4.213; P < 0.001; passive condition: Z = -3.864; P < 0.001). The pain levels did not differ between conditions (Z = -0.137, P = 0.45). Interestingly, the reported match/congruency of the patients' moods and emotions expressed by the chosen music pieces correlated with changes in pain perception (r = -0.438, P = 0.007), and the match of the patients' own emotional state with the music was significantly higher during the active condition (Mdn = 7.7) than during the passive condition (Mdn = 6.35; Z = -3.429; P < 0.001). No significant correlation between changes in pain intensity and changes in heart rate variability were observed (r = 0.15, P = 0.952). The rather heterogeneous patient sample limits specific conclusions about effects on certain pain conditions, and the focus on immediate effects precludes conclusions about long-term outcomes. Music feedback during physical exercise may be beneficial in increasing motivation in patients with chronic pain. A stronger match of emotions expressed by music feedback and the patient's own emotional state seems to influence pain perception.
Clinical relevance
In hospitalized patients with chronic pain, does active music feedback during ergometer exercise (active condition) produce greater improvements in motivation, emotional state, and pain perception compared to passive music listening during the same exercise (passive condition)? __SNAPSHOT__ {"studyDesign":"Randomized crossover trial (within-subject design; each participant underwent both conditions in randomized order)","setting":"Acute inpatient pain medicine clinic (single site; country not reported in abstract)","sampleSize":"n = 43 enrolled; n = 40 contributed to the primary motivation analysis (t-test df = 39 implies n = 40 completers)","population":"Adults with heterogeneous chronic pain conditions during an acute inpatient clinic stay; specific diagnoses, duration of pain, age, sex distribution, and comorbidities not reported in the abstract","intervention":"Active condition: music feedback during ergometer training — participants actively identified emotionally with music in real time during exercise (exact feedback mechanism not fully described in abstract)","comparator":"Passive condition: standard music listening (same songs across 4 genres) during ergometer training, without interactive music feedback","primaryOutcome":"Motivation to exercise, measured by active engagement during the training interval (metric operationalization not fully specified in abstract beyond the t-test statistic reported)","followUp":"Acute inpatient stay duration; no long-term follow-up reported","fundingSource":"Not reported"}
Key findings
The primary reported result showed that motivation to exercise was significantly greater during the active music feedback condition than during the passive music listening condition (t(39) = 3.013, P = 0.006; 95% CI for the difference in active engagement: 0.0104 to 0.0529). The absolute mean difference in active engagement falls entirely within the reported confidence interval (point estimate not explicitly stated; midpoint of CI ≈ 0.0317, calculated). The clinical magnitude of this difference on the engagement scale used cannot be fully assessed without knowledge of the scale's range and minimum clinically important difference, which are not reported in the abstract. The abstract was truncated and does not report results for the co-stated outcomes of emotional state and pain levels. No adverse events are mentioned. No effect sizes (Cohen's d or partial η²), NNT, or NNH are calculable from the available data.
Practice implications
This study provides preliminary evidence that active emotional engagement with music during aerobic exercise (ergometer training) may enhance exercise motivation compared to passive music listening in a heterogeneous chronic pain inpatient population. However, critical limitations substantially constrain interpretation: (1) the abstract is truncated — results for pain perception and emotional state outcomes, which are central to the study's stated aims, are not reported here and therefore cannot be evaluated; (2) the crossover design, while efficient, is susceptible to carryover effects, and no washout period or counterbalancing details are described; (3) the sample is small (n ≈ 40 completers) and diagnostically heterogeneous, limiting both statistical power for secondary outcomes and generalizability to any specific pain condition; (4) blinding of participants is not possible given the nature of the intervention, introducing performance and demand-characteristic bias; (5) the 'active engagement' metric used to assess motivation has unknown psychometric properties and unknown clinical relevance; (6) the duration of benefit and whether any observed effects persist beyond the training session are unknown. Only the abstract was available for this review, which is an important limitation. Findings should not be used to change practice at this time. __LIMITATIONS__ Abstract truncated — results for pain and emotional state outcomes are missing entirely,Small sample size (n ≈ 40 completers); underpowered for secondary outcomes and subgroup analyses,Heterogeneous chronic pain diagnoses reduce internal coherence and limit condition-specific applicability,No participant blinding possible; high risk of performance bias and demand characteristics,Crossover design: carryover effects not addressed; washout period not described,Single acute inpatient setting; results may not generalize to outpatient or community-based chronic pain populations,Primary outcome measure ('active engagement' scale) has unknown psychometric properties and no established minimum clinically important difference,No long-term follow-up; durability of any motivational or analgesic effect is unknown,Funding source not reported; potential conflicts of interest cannot be assessed,Statistical significance (P = 0.006) established for motivation, but clinical significance is indeterminate given the narrow absolute difference (CI: 0.0104–0.0529) on an uncharacterized scale __BOTTOM_LINE_CATEGORY__ promising_but_preliminary __BOTTOM_LINE__ This small randomized crossover trial found that active music feedback during ergometer exercise significantly increased exercise motivation compared to passive music listening in chronic pain inpatients, but the abstract is truncated and does not report the pain or emotional state outcomes central to the study's primary aims. The clinical meaningfulness of the motivation difference is indeterminate without knowledge of the outcome scale's properties. Practice change is not warranted; larger, methodologically rigorous trials with fully reported outcomes are needed before this intervention can be recommended in clinical settings.
