Assessing Spinal Pain With an Artificial Intelligence-assisted Whole Body Electrical Stimulation Device

May 8, 2026 updated by: Kübra Okuyucu, Amasya University

Validity of an AI-Supported Whole-Body Electrical Stimulation Device for Spinal Pain Assessment: A Comparison With Self-Reported Pain Scores

The goal of this observational study is to investigate the correlation between self-reported pain and the measurements obtained using an artificial intelligence-assisted whole-body electrical stimulation device (StimaWELL 120MTRS system) in individuals with chronic back pain. The main question it aims to answer is: Is there any correlation between the pain intensity assessed with StimaWELL 120MTRS system, dolorimeter and self-report in adults with chronic back pain? The patients who have back pain for the duration longer than 3 months and have been eximaned by a medical doctor will be assessed with StimaWELL 120MTRS system, dolorimeter, and will be asked to rate their pain intensity in Numerical Pain Rating Scale.

Detailed Description

The goal of this observational study is to investigate the correlation between self-reported pain and the measurements obtained using an artificial intelligence-assisted whole-body electrical stimulation device (StimaWELL 120MTRS system) in individuals with chronic back pain. This study is designed as an exploratory, cross-sectional study. After obtaining written and verbal informed consent, 200 patients with back pain will be asked about their age, sex, height, weight, and duration of back pain. Pain location and intensity will be assessed by one of the investigators using a body diagram and the Numerical Pain Rating Scale (NPRS). In addition, the patients will be evaluated by another investigator using the StimaWELL 120MTRS device, and using the dolorimeter for the pressure pain threshold (PPT). PPT will be assessed at four bilateral points: the upper trapezius, the lower trapezius, 5 cm lateral to the spinous process of the L3 vertebra, and 2 cm cranial to the posterior superior iliac spine. To achieve 80% power at a 5% significance level, assuming a medium effect size, estimated minimum sample size is calculated as 158 participants. Accordingly, the target sample size is set at 200 participants. Pearson's or Spearman's correlation coefficient will be used to determine the relationship between pain values measured by the artificial intelligence-assisted device and patient-reported pain scores (0-10) or pressure pain threshold. To assess the relationships among the three continuous variables obtained in this study-patient-reported pain scores (0-10), device-measured pain values, and pressure pain threshold-repeated-measures ANOVA or the Friedman test will be used to compare their means.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pain intensity measured by the StimaWELL 120MTRS system
Time Frame: baseline, one time
The StimaWELL® EMS device is a high-tech modulated low-frequency, 12-channel, mid-frequency stimulation device. The output of the calibration process will be recorded as data to use in the analysis.
baseline, one time
Pressure pain threshold
Time Frame: baseline, pre-procedure
PPT will be assessed using a dolorimeter at four bilateral points (upper trapezius, lower trapezius, 5 cm lateral to L3 spinous process, and 2 cm cranial to the posterior superior iliac spine).
baseline, pre-procedure
Patient-reported pain
Time Frame: baseline, pre-procedure
Participants will be asked to indicate the location of their back pain experienced over the last week on a body diagram, which shows the regions where the electrodes will be placed in a faint outline. For each marked region, participants will be asked to rate their pain intensity using the Numerical Pain Rating Scale. The scale ranges from 0 to 10, where 0 indicates "no pain" and 10 indicates "worst imaginable pain." Higher scores represent greater pain intensity.
