Ultrasound for Peripheral Nerve Modulation
Assessment of Wearable Ultrasound for Modulation
This study evaluates an ultrasound device designed to reduce pain by targeting peripheral nerves without surgery or medication. The device is placed on the skin over the area of pain and delivers controlled ultrasound stimulation.
Adults with nerve-related pain will participate in a single study visit that includes stimulation sessions and pain assessments.
The goal of this study is to determine whether non-invasive ultrasound can safely and effectively reduce pain and to assess whether this approach is practical for future clinical use.

Beskrivelse
Inclusion Criteria:
- Stated willingness to comply with all study procedures and availability for the duration of the study
- Persons aged 18 and older.
- In good general health as evidenced by medical history
- Chronic pain located in the distribution of any of the target nerves of interest, including the occipital, suprascapular, median, femoral/leg, stellate ganglion/vagus nerves, neuroma, or amputees.
Exclusion Criteria:
- Patients with compromised skin integrity for whom device placement would result in increased risk of harm (such as those with extensive burns, active dermatologic conditions, or wounds that would prevent safe device placement)
- Pregnant patients, as the devices have not been validated in this population
- Additionally, the treating clinician may exclude any patient if they determine that study participation would be inappropriate for the patient's clinical condition.

Intervensjon / Behandling |
|---|---|
|
Sham-komparator: Sham
Participants undergo sham ultrasound stimulation that replicates all procedural aspects of active treatment without delivery of therapeutic acoustic energy.
|
Sham stimulation replicates all procedural aspects of active ultrasound neuromodulation, including device placement and operation, without delivery of therapeutic acoustic energy.
This condition serves as a control to account for placebo and procedural effects.
|
|
Eksperimentell: Ultrasound modulation
Participants receive ultrasound stimulation at predefined parameters to evaluate neuromodulatory effects on the target peripheral nerve.
|
Non-invasive focused ultrasound stimulation is applied to a target peripheral nerve.

Incidence of Device-Related Adverse Events
Tidsramme: From treatment to the next day (up to two days)
|
Assessment of the number and severity of device- and procedure-related adverse events associated with focused ultrasound neuromodulation.
Events will be graded according to standard clinical criteria, including pain, skin irritation, thermal effects, or neurologic symptoms.

Change in Numerical Pain Rating Scale
Tidsramme: During, immediately after each stimulation block, and one day after the treatment (up to two days)
|
Participant-reported tolerability assessed using a numerical pain rating scale (e.g., discomfort or pain score during stimulation).
The scale ranges from 1 (no pain) through 10 (worst pain).
|
During, immediately after each stimulation block, and one day after the treatment (up to two days)
