This page summarizes published research on pulsed electromagnetic fields (PEMF) and neck pain, including studies of persistent neck pain, cervical osteoarthritis, disc herniation, and non-specific mechanical neck pain. It does not make a claim that an ElectroMeds device or another PEMF device is a treatment for neck pain.
What researchers have studied
The neck-pain literature is not one uniform body of research. The studies below enrolled people with different diagnoses and used different field types, applicator formats, comparison groups, outcome measures, and follow-up periods. Foley-Nolan and colleagues studied persistent neck pain in 20 people using a 27 MHz neck-directed system. Trock and Sutbeyaz studied cervical osteoarthritis. Hattapo?lu studied cervical disc herniation, while Karaka? and Gök enrolled people with chronic non-specific mechanical neck pain.
Those distinctions matter. A result in cervical osteoarthritis is not automatically a result in non-specific neck pain, and a whole-body mat is not the same study format as a localized applicator. Several trials included physical therapy, exercise, heat, or TENS in both groups, so their comparisons ask whether the assigned field added something within that particular care package. The 2013 Cochrane review considered electrotherapy for neck pain more broadly and judged the relevant evidence low or very low quality. Taken together, these studies provide signals in more than one direction, not a settled answer for one device or one type of neck pain.
The studies
Kroeling et al. 2013 systematic review of electrotherapy for neck pain
This Cochrane systematic review assessed randomized trials of several electrotherapy approaches for neck pain, not PEMF alone. Kroeling and colleagues included 20 trials covering 11 types of electrotherapy and described the PEMF evidence as very low quality. Their review reported that a small body of PEMF evidence suggested a short-term difference from placebo, while also finding insufficient evidence for firm clinical conclusions across electrotherapy methods. It also reported null findings for some other magnetic approaches, including magnetic necklaces.
The immediate limitation is breadth. The review combines varied technologies and neck-pain presentations, so it cannot establish that findings from one PEMF apparatus apply to a different apparatus, or that results from one diagnostic group apply to another. Its evidence-quality judgments and heterogeneous included trials are central to interpreting the more favorable individual studies below.

Foley-Nolan et al. 1990 persistent neck-pain trial
Foley-Nolan and colleagues conducted a double-blind, placebo-controlled trial in 20 people with neck pain lasting more than eight weeks. For the first three weeks, 10 participants received the active low-energy pulsed high-frequency 27 MHz system and 10 received a look-alike placebo unit. At the three-week comparison, the active-group scores for pain and range of movement had improved more than the placebo-group scores. In the second three-week period, both groups used active units, and the authors reported improvement in both groups.
This is the established 1990 placebo-controlled study cited on the original page, and its randomized, blinded comparison is a strength. Its immediate limits are the very small sample, brief blinded phase, older technology, and crossover-like second phase in which both groups received active units. The study does not establish whether its observations apply to a different neck-pain diagnosis, a different field configuration, or a current retail device.

Trock et al. 1994 cervical osteoarthritis trial
Trock and colleagues reported randomized, double-blind, placebo-controlled trials in knee and cervical-spine osteoarthritis. The cervical-spine trial enrolled 81 people and compared 18 active or placebo sessions. At the end of the study and at one-month follow-up, the active group’s average change from baseline was greater than the placebo group’s for several outcomes. According to the abstract, between-group differences in the cervical cohort reached statistical significance at one or more time points for pain, pain on movement, and tenderness.
This trial addressed cervical osteoarthritis rather than neck pain without a defined structural diagnosis. The abstract does not provide effect sizes for every outcome, and the trial is now more than three decades old. A short follow-up and the absence of later, closely matched replication limit what can be inferred beyond this particular study population and apparatus.

Sutbeyaz et al. 2006 cervical osteoarthritis trial
Sutbeyaz and colleagues randomized 34 people with cervical osteoarthritis in a double-blind, sham-controlled study. Their protocol used a whole-body mat, so its field-delivery format differs from a neck-directed applicator. The authors reported statistically significant pre-to-post changes in pain, active range of motion, paravertebral muscle spasm, and the Neck Pain and Disability Scale in the active group, with no corresponding change reported in the sham group.
The small sample and three-week assessment window are immediate constraints. The diagnosis was cervical osteoarthritis, and participants lay on a full-body mat rather than using a localized format. That condition and format mismatch mean this study cannot answer how a portable, localized device would compare, or whether the findings extend to other causes of neck pain.

Hattapo?lu et al. 2019 cervical disc-herniation trial
Hattapo?lu and colleagues randomly assigned 64 people with cervical disc herniation to conventional physical therapy with active PEMF or to the same conventional physical therapy with a sham field. Both groups received TENS and hot packs, and both improved on several measures after the study period. At 12 weeks, the active group had a lower pain score and a more favorable sleep subscore than the sham group, while the report did not show a between-group difference for the Neck Pain and Disability Scale at that time.
The mixed pattern is important. The trial evaluated PEMF as part of a combined program, not as a stand-alone exposure, and most outcomes did not show a clear active-versus-sham separation. Its sample was modest, follow-up was limited to 12 weeks, and cervical disc herniation is not interchangeable with non-specific neck pain.

PMID: 31385489. DOI: 10.3906/sag-1901-65.
Karaka? and Gök 2020 chronic non-specific neck-pain trial
Karaka? and Gök conducted a double-blind, randomized, placebo-controlled study in 63 people with chronic non-specific mechanical neck pain. Both groups received the same three-week conventional physical-therapy program; one group received active PEMF and the other sham PEMF. Pain, disability, quality-of-life measures, and physician global assessment improved after treatment in both groups. The active group was not statistically superior to the sham group on the outcome parameters.
This is a direct null result in a population closer to everyday non-specific mechanical neck pain than the osteoarthritis and disc-herniation studies. It does not show whether a different field design, a different care context, or longer follow-up would produce another result. Still, its blinded sham comparison means the lack of an added group difference should be weighed alongside the positive findings of smaller or differently designed trials.

PMID: 32760890. DOI: 10.5606/tftrd.2020.5169.
How strong is this evidence?
The evidence is limited and mixed. There are randomized and, in several cases, blinded trials, which are useful designs for studying subjective outcomes such as pain ratings. Yet the trials are small, with samples ranging from 20 to 86, and they do not study one consistent population. Persistent neck pain, cervical osteoarthritis, cervical disc herniation, and non-specific mechanical neck pain can differ in cause, prognosis, and response to a study’s co-interventions. Results cannot simply be pooled as though they answer one question.
The devices and comparisons also vary. Foley-Nolan used a 27 MHz neck-directed system; Sutbeyaz used a whole-body mat; and later trials added PEMF or sham exposure to exercise or conventional physical therapy. These differences make it hard to identify whether findings reflect the people enrolled, the field configuration, accompanying care, study expectations, or chance.
The results themselves point in different directions. Foley-Nolan, Trock, and Sutbeyaz reported favorable between-group findings in their respective settings. Hattapo?lu reported selected 12-week differences alongside several outcomes without a clear between-group difference. Karaka? and Gök found no added advantage over sham when both groups received conventional physical therapy. The Cochrane review’s low or very low certainty assessment, short follow-up, and limited direct replication support a cautious reading. This body of research does not establish what, if anything, applies to a particular person, diagnosis, or retail device.
What this means if you are considering a PEMF device
The most relevant device-format question for a localized neck area is whether a portable applicator can be positioned near that area. That is a relevance question, not evidence that one format produces a particular outcome. The 1990 Foley-Nolan study from the original page used a neck-directed, wearable system, while the 2006 Sutbeyaz study used a full-body mat. Those studies should not be treated as interchangeable simply because both used pulsed electromagnetic fields.
Before drawing comparisons, look for plain technical information about the applicator, waveform, frequency, field strength, and the way the study apparatus was used. A device description alone does not demonstrate that it matches the apparatus in a published trial. What PEMF is and this overview of portable PEMF machines provide background on formats and terminology. Published studies can inform questions to investigate, but they do not establish whether a consumer device will reproduce a research result or substitute for clinical evaluation or prescribed care.
Questions to ask before buying
- Does the seller clearly identify the applicator format and where it is intended to be positioned?
- Are waveform, frequency, field-strength, and power information available in a current manual or specification sheet?
- Does the product description distinguish its own configuration from the apparatus used in a cited study?
- What are the total price, included accessories, warranty terms, and return policy?
- Is the device portable enough for the location and setup you have in mind?
- Can you obtain readable instructions, customer support details, and the manufacturer’s current documentation before purchase?
This page summarizes published research for reference. It is not medical advice, and nothing here is a claim that any PEMF device treats, cures, or prevents any condition. PEMF is not appropriate for everyone — review PEMF contraindications and talk with your own physician before beginning any new therapy, particularly if you have an implanted electronic device, are pregnant, or are being treated for a serious medical condition.
