About the research

Sickle cell disease causes very painful episodes that can happen without warning. Pain is one of the biggest problems for people with SCD. Medicines like opioids can help, but they have serious side effects. Doctors are looking for other ways to treat pain.

Investigators have already found that music therapy - breathing exercises guided by a trained music therapist - can lower pain in adults with SCD. But investigators don't know exactly how it works yet inside the body.

This study will look at two possible reasons why music therapy helps:

  • It may calm the body's "fight-or-flight" (sympathetic) nervous system, which can make pain worse when it is too active.
  • It may boost the "calming" (parasympathetic) nervous system, which may ease pain and reduce inflammation.
  • It may lower swelling and inflammation in the body, which also drives pain.

Who may be able to participate?

The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.

Inclusion Criteria:

  • (1) are age ≥18 years
  • (2) have a diagnosis of SCD documented in the electronic health record (EHR)--- (3) meet Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks-American Pain Society Pain Taxonomy (AAPT) criteria for chronic SCD pain
  • (4) are able to speak and understand English
  • (5) have an email address and access to a mobile device with a functioning data plan (to get pain diaries)
  • (6) report that pain interfered with daily activities at least 1-2 days in past week will be eligible for the study. -

Exclusion Criteria:

  • (1) have \< 3 vaso-occlusive crises (VOCs) per year and no VOCs in the past 3 months
  • (2) have significant visual, hearing, psychiatric or cognitive impairment
  • (3) are currently engaged in mind-body therapies under the supervision of a healthcare professional specifically for pain management
  • (4) have a planned major medical event in next 8 weeks (e.g., childbirth, orthopedic surgery, gene therapy, stem cell transplant) that does not include routine disease modifying therapies (e.g., blood transfusions)
  • (5) are unable or unwilling to refrain from stopping all medications that interfere with the autonomic nervous system for 5 half-lives prior to autonomic testing and from changing their medication regimen during the 2 weeks that separate autonomic testings and blood draws
  • (6) develop active VOC requiring hospitalization at enrollment
  • (7) have conditions that would significantly affect autonomic testing interpretation, such as severe arrhythmias or pregnancy, will be excluded from the study.

Treatment, groups and participation

The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.

Assignment

Masking
No masking
Music Therapy

The MT-BC will engage the participant in a 20-minute deep breathing exercise with live music beating at a defined tempo. Participants will repeat this session on their own.

Behavioral: Music Therapy

Music Therapy BEHAVIORAL

Participants will undergo a 20-minute music therapy session with a board certified music therapist, then will repeat this on their own once daily for 2 weeks.

Prepare your questions

What researchers are measuring

Outcome measures describe what is being studied. They are not proof that a treatment works.

Primary measures

Change in electrodermal activity (EDA) as measured by change in electrical potential at the surface of the skin

Time frame: Baseline and after 2 weeks

Lower EDA reflects less sympathetic tone

Change in Quantitative Sudomotor Axon Reflex Test (QSART) as measured by sweat output values

Time frame: Baseline and after 2 weeks

Lower QSART values reflect less sympathetic activity

Changes in Pupillometry parameters as measured by constriction velocity

Time frame: Baseline and after 2 weeks

Faster constriction velocity indicates a higher pupillary vagal tone.

Changes in Pupillometry parameters as measured by percent reflex amplitude

Time frame: Baseline and after 2 weeks

Larger percentage of reflex amplitude indicates higher pupillary vagal tone.

Changes in Pupillometry parameters as measured by dilation velocity.

Time frame: Baseline and after 2 weeks.

Slower dilation velocity indicates lower pupillary sympathetic tone.

Change in Heart Rate Response to deep breathing

Time frame: Baseline and after 2 weeks

Increased heart rate response to deep breathing denotes increased cardiovagal tone.

Measurement of average supine resting Blood Pressure (BP)

Time frame: Baseline and after 2 weeks

Lower average resting BP denote lower cardiac sympathetic tone

Measurement of average supine resting Heart Rate (HR)

Time frame: Baseline and after 2 weeks

Lower average resting HR denote lower cardiac sympathetic tone

Change in supine resting respiratory rate

Time frame: Baseline and after 2 weeks

A lower resting respiratory rate reflects a shift of autonomic balance toward parasympathetic (vagal) dominance with reduced central sympathetic outflow.

Change in the maximum heart rate during the Valsalva maneuver

Time frame: Baseline and after 2 weeks

An increased Valsalva Ratio (maximum heart rate to the minimum heart rate) reflects an increase in cardiac parasympathetic tone.

Change in the minimum heart rate shortly after the Valsalva maneuver

Time frame: Baseline and after 2 weeks

An increased Valsalva Ratio (maximum heart rate to the minimum heart rate) reflects an increase in cardiac parasympathetic tone.

Secondary measures

Change in C Reactive Protein as measured by bloodwork

Time frame: Baseline and after 2 weeks

Lower levels of CRP indicate lower levels of inflammation

Change in Cytokine levels as measured by bloodwork

Time frame: Baseline and after 2 weeks

Lower levels of cytokines indicate lower levels of inflammation

Other measures

Pain intensity changes as measured by the Visual Analog Scale (VAS)

Time frame: Baseline and after 2 weeks of daily music therapy

The VAS is a straight 100 mm line-usually horizontal-with descriptive word anchors at each end representing opposite extremes of a subjective experience, such as 0 being "no pain" and 10 being "worst possible pain".

Pain intensity changes as measured by the Brief Pain Inventory (BPI)

Time frame: Baseline and after 2 weeks of daily music therapy

Brief Pain Inventory (BPI) is a self-administered questionnaire used to evaluate pain severity and how pain interferes with daily life on scales from 0 to 10, with 0 being no pain, and 10 being severe pain.

Pain diaries

Time frame: Daily for 2 weeks

Daily pain intensity and analgesic use

Music therapy adherence

Time frame: Daily for 2 weeks

Daily log of adherence to the home-based music therapy protocol
