Stroke survivors who received music interventions walked 11.34 metres per minute faster than controls, the strongest gait result in the Cochrane review of music for acquired brain injury (Cochrane Database of Systematic Reviews, Magee et al. 2017). The picture is far less uniform elsewhere: in dementia, the 2025 Cochrane update of 30 studies and 1,720 participants found only a slight effect on depression and no lasting benefit, and the multinational MIDDEL trial of 1,021 care home residents found no significant effect of group music therapy on depression at six months. In palliative care, a 2026 meta-analysis of 9 trials linked music-based interventions to lower pain and better quality of life, but on very low certainty evidence. This roundup focuses on clinical outcomes in neurological and end-of-life care; the profession’s workforce, salaries and market are covered in our music therapy statistics. We aggregated data from the Cochrane Library, The Lancet Healthy Longevity, Frontiers in Neurology, Palliative Medicine, the Alzheimer’s Association, the CDC, the Parkinson’s Foundation, ClinicalTrials.gov and the other primary sources listed in the methodology.
TL;DR
- Music interventions after stroke raised gait velocity by 11.34 m/min (Cochrane, Music Interventions for Acquired Brain Injury 2017).
- Music-based therapy probably improves depression in dementia only slightly, SMD -0.23 (Cochrane, Music-Based Therapeutic Interventions for People with Dementia 2025).
- No dementia outcome stayed better than usual care four or more weeks after treatment (Cochrane, 2025).
- MIDDEL, 1,021 residents in 6 countries: no significant depression effect for group music therapy at 6 months (The Lancet Healthy Longevity, 2025).
- 21 RCTs, 1,029 stroke patients: activities of daily living improved by SMD 0.88 (Frontiers in Neurology, Liu et al. 2026).
- Post-stroke depression fell 4.76 points on the Hamilton scale across 37 RCTs and 2,776 patients (Medicine, Li et al. 2025).
- Aphasia: music therapy improved repetition (SMD 0.37), not naming or comprehension (Frontiers in Neurology, Gu et al. 2024).
- Parkinson’s gait speed improved by 0.53 SD with rhythmic auditory stimulation (Holistic Nursing Practice, Burrai et al. 2024).
- Advanced cancer palliative care: quality of life SMD 0.92, very low certainty (Journal of Clinical Medicine, Smilowska et al. 2026).
- Cancer patients: anxiety down 7.73 units across 17 studies and 1,381 participants (Cochrane, Music Interventions for People with Cancer 2021).
- 1,430 music therapy studies registered, 163 recruiting (ClinicalTrials.gov, October 2026).
1. Dementia: Small Short-Term Gains, No Proven Lasting Effect
The size of the need is not in question: an estimated 7.4 million Americans age 65 and older live with Alzheimer’s in 2026, and health and long-term care costs for dementia are projected to reach 409 billion dollars (Alzheimer’s Association, 2026 Alzheimer’s Disease Facts and Figures). Because receptivity to music often persists into advanced dementia, music is one of the most widely tried non-drug options in care homes.
The best evidence says it helps mood a little, and only while it lasts. The March 2025 Cochrane update pooled 30 randomized studies with 1,720 participants in 15 countries and found music-based interventions probably improve depressive symptoms slightly (SMD -0.23, 9 studies, 441 participants, moderate certainty) and may improve overall behavioural problems (SMD -0.31), but likely do not improve agitation or aggression (SMD -0.05) (Cochrane, van der Steen et al. 2025). The largest trial so far reinforces the caution: MIDDEL randomized 86 care home units in Australia, Germany, the Netherlands, Norway, Turkiye and the UK and found no significant effect of either recreational choir singing or group music therapy on depression scores at six months, with country the strongest predictor of differences (The Lancet Healthy Longevity, Sveinsdottir et al. 2025).

| Anxiety vs other activities | SMD -0.75 (10 studies, 291 participants; very low certainty) | Cochrane, van der Steen et al. 2025 |

Context note: a Norwegian secondary analysis of a music-based caregiving trial (232 residents, mean age 86) found no significant difference in Neuropsychiatric Inventory scores between intervention and control groups (BMC Geriatrics, Myrenget et al. 2026). Effects on cognition (SMD 0.19) and emotional well-being (SMD 0.14) were not significant in the Cochrane analysis, and ten studies contributed long-term data, none showing durable benefit.
2. Stroke Rehabilitation: The Strongest Motor Evidence
If music therapy has a flagship clinical indication, it is walking after stroke. The Cochrane review of 29 trials and 775 participants found gait velocity improved by 11.34 metres per minute, stride length by 0.12 metres and cadence by 10.77 steps per minute (Cochrane, Magee et al. 2017). The authors linked the gait gains to rhythmic auditory stimulation, where a steady beat paces each step, and rated the velocity evidence as moderate quality, unusually high for this field.
Newer meta-analyses point in the same direction and widen the scope beyond gait. A 2026 review of 21 RCTs with 1,029 stroke patients found music-based interventions added to conventional rehabilitation improved lower limb motor function (SMD 0.99), activities of daily living (SMD 0.88), gait speed (SMD 0.89), upper limb function (SMD 0.58) and balance (SMD 0.45) (Frontiers in Neurology, Liu et al. 2026). The scale of the population makes even moderate effects relevant: more than 795,000 people in the US have a stroke every year, and stroke reduces mobility in more than half of survivors age 65 and older (CDC, Stroke Facts).
| Metric | Value | Source |
|---|---|---|
| Gait velocity after stroke | +11.34 m/min (9 trials, 268 participants; moderate quality) | Cochrane, Magee et al. 2017 |
| Stride length | +0.12 m (5 trials, 129 participants; moderate quality) | Cochrane, Magee et al. 2017 |
| Gait cadence | +10.77 steps/min (7 trials, 223 participants; low quality) | Cochrane, Magee et al. 2017 |
| Stroke-specific quality of life | +0.89 SD (2 trials, 53 participants; low quality) | Cochrane, Magee et al. 2017 |
| Lower limb motor function and daily living | SMD 0.99 and SMD 0.88 (21 RCTs, 1,029 patients) | Frontiers in Neurology, Liu et al. 2026 |
| Gait speed, stride length, step frequency | SMD 0.81, 0.80 and 0.89 (12 studies, 388 participants) | Topics in Stroke Rehabilitation, Li et al. 2026 |
| Annual US strokes | More than 795,000 | CDC, Stroke Facts (updated October 2024) |
Context note: the Cochrane upper extremity result (a 1.08 second faster Wolf Motor Function Test time) rests on 2 trials and very low quality evidence. The Cochrane search ran to June 2015, so the 2017 review is the most recent available Cochrane analysis for brain injury; CDC puts US stroke-related costs at nearly 56.2 billion dollars in 2019-2020.
3. Aphasia and Post-Stroke Mood: Narrow Language Gains, Large Mood Effects
Language recovery is where music-based techniques such as melodic intonation have the longest history, and where the data are most specific. A 2024 meta-analysis of 11 RCTs with 329 patients found neurologic music therapy improved repetition (SMD 0.37) but not naming, comprehension, spontaneous speech or communication, and only programs above 20 hours reached significance (SMD 0.43) (Frontiers in Neurology, Gu et al. 2024). Dose looks like the variable that separates trials that work from those that do not. The broader burden of the condition is documented in our aphasia statistics and the services side in our speech therapy statistics.
Mood results are much larger, and that is reason for caution as much as optimism. A 2025 meta-analysis of 37 RCTs and 2,776 patients with post-stroke depression found music lowered Hamilton depression scores by 4.76 points and Zung anxiety scores by 7.34 points (Medicine, Li et al. 2025). Effects of that size across dozens of small trials usually signal heterogeneous designs, so they should be read alongside the general evidence in our depression statistics.
| Metric | Value | Source |
|---|---|---|
| Communication after brain injury | +0.75 SD (3 trials, 67 participants; very low quality) | Cochrane, Magee et al. 2017 |
| Neurologic music therapy, repetition in non-fluent aphasia | SMD 0.37 (11 RCTs, 329 patients) | Frontiers in Neurology, Gu et al. 2024 |
| Repetition, programs over 20 hours | SMD 0.43 (20 hours or less: not significant) | Frontiers in Neurology, Gu et al. 2024 |
| Functional communication and naming in aphasia | MD 1.45 and MD 11.44 (6 studies, 115 patients) | Neurological Sciences, Liu et al. 2022 |
| Post-stroke depression, Hamilton scale | MD -4.76 (37 RCTs, 2,776 patients) | Medicine, Li et al. 2025 |
| Post-stroke anxiety, Zung SAS | MD -7.34 | Medicine, Li et al. 2025 |
| Music-supported therapy, cognition after stroke | MMSE +2.53, MoCA +3.59 (72 studies, 5,543 people) | Cerebrovascular Diseases, Wang et al. 2025 |
Context note: the 2022 Neurological Sciences meta-analysis also reported a repetition gain of 6.49 points, but pooled only 115 patients. Source: Cerebrovascular Diseases, Wang et al. 2025.
4. Parkinson’s Disease: Rhythm as a Gait Cue
The logic that drives the stroke gait results carries over to Parkinson’s, where freezing and shortened steps are core motor problems. A 2024 meta-analysis of 5 RCTs with 209 patients found rhythmic auditory stimulation improved gait speed by 0.53 standard deviation units and stride length by 0.51 SD units more than controls, with no adverse events reported (Holistic Nursing Practice, Burrai et al. 2024). The authors also rated the evidence low quality, because no trial was blinded.
That is a thin base for a condition this common. About 1.1 million people in the US live with Parkinson’s, close to 90,000 are diagnosed each year, and the number is expected to reach 1.2 million by 2030 (Parkinson’s Foundation, Statistics). The registry pipeline is modest too, which suggests the evidence will stay small-sample for several more years.
| Metric | Value | Source |
|---|---|---|
| RCTs and patients pooled | 5 RCTs, 209 patients | Holistic Nursing Practice, Burrai et al. 2024 |
| Gait speed vs control | +0.53 SD (95% CI 0.23 to 0.83) | Holistic Nursing Practice, Burrai et al. 2024 |
| Stride length vs control | +0.51 SD (95% CI 0.18 to 0.84) | Holistic Nursing Practice, Burrai et al. 2024 |
| Adverse events and evidence quality | None identified; low quality (no blinding) | Holistic Nursing Practice, Burrai et al. 2024 |
| People living with Parkinson’s in the US | About 1.1 million (1.2 million by 2030) | Parkinson’s Foundation, Statistics page (accessed October 2026) |
| New US diagnoses per year | Nearly 90,000 | Parkinson’s Foundation, Statistics page (accessed October 2026) |
| Registered music therapy studies on Parkinson’s | 36 | ClinicalTrials.gov, October 2026 |
Context note: the Parkinson’s Foundation estimates more than 10 million people live with the disease worldwide. The NIH National Center for Complementary and Integrative Health notes that the NIH and Kennedy Center Sound Health initiative began funding research in 2019, with applications including Parkinson’s disease, stroke and chronic pain (NCCIH, Music and Health, 2022).
5. Palliative and End-of-Life Care: Meaning Over Symptom Scores
End-of-life trials tend to show music therapy moving existential outcomes more reliably than standard quality-of-life scales. The multicentre Song of Life trial (104 palliative patients) found no difference on its primary psychological quality-of-life outcome (p = 0.72), yet patients reported higher spiritual well-being (d = 0.52) and ego-integrity (d = 0.72), and families rated the legacy effect very large (d = 2.03) (Palliative Medicine, Warth et al. 2021). A 2023 meta-analysis of 7 RCTs with 747 advanced cancer patients found the same split: spiritual well-being improved (MD 0.43), while quality of life, pain and psychological distress did not differ significantly (Seminars in Oncology Nursing, Huda et al. 2023).
Pain data are more encouraging but weak. The newest meta-analysis, 9 RCTs with 675 advanced cancer patients, linked music added to routine palliative care to lower pain intensity (SMD -0.51) and higher quality of life (SMD 0.92), but rated certainty very low and found no randomized trials of other art therapies (Journal of Clinical Medicine, Smilowska et al. 2026). Related receptive approaches are tracked in our sound therapy statistics.
| Metric | Value | Source |
|---|---|---|
| Pain intensity, advanced cancer palliative care | SMD -0.51 (k = 3, n = 224; I2 67.69%) | Journal of Clinical Medicine, Smilowska et al. 2026 |
| Quality of life, advanced cancer palliative care | SMD 0.92 (k = 2, n = 168; very low certainty) | Journal of Clinical Medicine, Smilowska et al. 2026 |
| Spiritual well-being, advanced cancer | MD 0.43 (7 RCTs, 747 patients) | Seminars in Oncology Nursing, Huda et al. 2023 |
| Song of Life: spiritual well-being, ego-integrity | d = 0.52 and d = 0.72 (104 patients) | Palliative Medicine, Warth et al. 2021 |
| Song of Life: distress vs mindfulness | b = -0.83, p = .02 | Supportive Care in Cancer, Koehler et al. 2022 |
| Hypnosis and music in palliative care, pain | Effect size -0.42 (4 RCTs plus 7 pre-post studies) | BMJ Supportive and Palliative Care, Bissonnette et al. 2024 |
| Registered music therapy studies, palliative | 25 | ClinicalTrials.gov, October 2026 |
Context note: in the BMJ Supportive and Palliative Care review only 3 of 11 studies reported written intervention protocols. Cochrane withdrew its 2010 review of music therapy for end-of-life care in 2014 and published a new protocol in December 2025 (Calvache et al.), so no current Cochrane estimate exists. A 2025 Journal of Pain and Symptom Management review of 26 studies (16 on music therapy) judged music and massage to have the most potential benefit for pain and quality of life.
6. Cancer Symptoms: The Largest Evidence Base
Cancer is where the volume of trials is highest, and the volume shows. The 2021 Cochrane review pooled 81 trials with 5,576 participants and found music interventions reduced anxiety by an average 7.73 units across 17 studies and 1,381 participants (Cochrane, Bradt et al. 2021). Pain (SMD -0.67), depression (SMD -0.41) and fatigue (SMD -0.28) also improved, yet nearly every estimate carries low or very low certainty because of small, unblinded trials.
The most useful finding for health systems is about who delivers the music. Interventions led by trained music therapists produced consistent results, while recorded music medicine programs did not, a distinction that matters for hospitals tempted to replace clinicians with playlists.
| Metric | Value | Source |
|---|---|---|
| Trials and participants | 81 trials, 5,576 participants (74 adult, 7 pediatric) | Cochrane, Bradt et al. 2021 |
| Anxiety, adults | -7.73 units (17 studies, 1,381 participants) | Cochrane, Bradt et al. 2021 |
| Depression, adults | SMD -0.41 (12 studies, 1,021 participants) | Cochrane, Bradt et al. 2021 |
| Pain, adults | SMD -0.67 (12 studies, 632 participants; very low certainty) | Cochrane, Bradt et al. 2021 |
| Fatigue, adults | SMD -0.28 (10 studies, 498 participants; low certainty) | Cochrane, Bradt et al. 2021 |
| Quality of life, adults | SMD 0.88 (95% CI -0.31 to 2.08), very uncertain | Cochrane, Bradt et al. 2021 |
| Hospice treatment compliance, advanced breast cancer | 96.67% with music therapy vs 80.00% hospice care alone (240 patients, retrospective) | Noise and Health, Wu et al. 2025 |
Context note: the Wu et al. study is retrospective rather than randomized, and covers two hospitals in Yancheng, China (Noise and Health, Wu et al. 2025). The Cochrane review searched literature to 2021, making it the most recent available Cochrane estimate for oncology.
7. The Research Pipeline: What Comes Next
The trial base is growing faster than the certainty of its conclusions. ClinicalTrials.gov listed 1,430 studies with music therapy as an intervention in October 2026, 163 of them actively recruiting (ClinicalTrials.gov API query). Dementia leads the condition counts with 108 registered studies, ahead of stroke at 60. Cochrane has also opened new reviews on end-of-life care (protocol December 2025), haemodialysis (protocol April 2025) and chronic pain (protocol May 2026), so several of the headline estimates in this article will be replaced.
The broader evidence base is large but uneven. The WHO’s 2019 scoping review on arts and health drew on results from over 3,000 studies across prevention, promotion and treatment (WHO Regional Office for Europe, Health Evidence Network synthesis report 67), and more than 10,000 therapists hold the MT-BC credential from a certifying board established in 1983 (Certification Board for Music Therapists).

| Board-certified music therapists | More than 10,000 (board established 1983) | Certification Board for Music Therapists, 2026 |
Context note: registry counts include completed, withdrawn and non-US studies, and a study can appear under several conditions. NCCIH cautions that many reported benefits come from observations of individuals or small groups and that more rigorous studies are needed.

- Data watch: Most recent available Cochrane data for stroke and brain injury is Magee et al. 2017 (search to June 2015), and for cancer Bradt et al. 2021; Cochrane end-of-life, haemodialysis and chronic pain reviews exist only as protocols, so no pooled Cochrane estimate is available for those areas yet. Sources conflict on dementia depression: the Cochrane review finds a slight benefit, the MIDDEL Australian cohort found a benefit for choir singing only, and the full multinational MIDDEL trial found no significant effect for either arm. Very large post-stroke mood and cognition effects (Li et al. 2025, Wang et al. 2025) come from pools of many small trials and should be weighed against the more conservative Cochrane estimates. Palliative pain and quality-of-life pools rest on 2 or 3 trials each. Wu et al. 2025 is retrospective. The 2021 AMTA hospice fact sheet PDF could not be read and was not used; the NIH Sound Health page returned 403, so Sound Health details come from NCCIH, and Sound Health funding totals were not verified and are omitted. PubMed and Europe PMC article pages blocked automated reading, so abstracts linked on PubMed were read through the Europe PMC REST API. ClinicalTrials.gov counts change daily.
Last updated: October 3, 2026. We update this roundup quarterly, and the next refresh is expected when Cochrane publishes the completed reviews on music therapy for end-of-life care and music-based interventions for chronic pain.
