Frequency Rhythmic Electrical Modulated Stimulation Effect in Peripheral Neuropathy Patients Severity of Cases and Qol. (FREMS)

June 9, 2026 updated by: Ibtihal Nassar, Beni-Suef University

Effects Of Frequency Rhythmic Electrical Modulated Stimulation (FREMS) On Blood Perfusion, Neuropathy Severity And Quality Of Life In Diabetic Patients With Peripheral Neuropathy And Lower Limb Ischemia: A Randomized Controlled Trial.

It's estimated that 50% of diabetic patients will have peripheral neuropathy as a complication within 3 years of the diabetes incidence [14], the goal of the study is to investigate this problem through the following objectives:

  1. To measure the effect of using FREMS therapy in diabetic neuropathy in interventional group on the blood perfusion, neuropathy severity and quality of life after 10 sessions compared to baseline.
  2. To measure the effect of using standard of care in diabetic neuropathy in control group on the blood perfusion, neuropathy severity and quality of life after 10 sessions compared to baseline.
  3. To compare the results between both interventional and control group.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

There are no clear guidelines for the treatment of peripheral neuropathy. While the American Diabetes Association stresses the importance of early detection and preventive measures, diagnosis and management are still on a developing path.

drugs used have common side effects; duloxetine and pregabalin patients are prone to nausea, fatigue, constipation, and decreased appetite; antidepressants may cause drowsiness, dry mouth, and muscle weakness; and opioids are prevented for long-term use due to the risk of addiction in all chronic cases like peripheral neuropathy. And most of the studies on these medications didn't report quality of life effects.

the lack of clear safe treatments with long-term effects on function and quality of life is the motive to conduct a randomized controlled trial on an objective assessment tool like duplex and a valid and reliable diagnostic tool like the neuropathy impairment score(NIS), measuring the effect of treatment on quality of life by the NORFOLK quality of life questionnaire after treatment with safe nonpharmacological treatment like FREMS therapy.

cases will be referred to the physiotherapy department by a diagnosis of peripheral neuropathy. samples will be assessed and divided into two groups randomly, Group A that will conduct a session with APTIVA FREMS therapy. Group B that will follow the conservative used treatment (doulextine and vitamin supplements) only.

The Number of sessions is 10 sessions consecutively within 10:14 days. The patients will be assessed by full neurological examination through the duplex APSV, neuropathy impairment score and NORFOLK quality of life questionnaire before and after the treatment.

outcomes will be collected by the researcher.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • patients diagnosed with DM

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

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
Neuropathy severity
Time Frame: From enrollment to the end of treatment at 10:14 days
neuropathy symptoms like (tingling, numbness, pain, loss of sensation) will be measured through neuropathy impairment score(NIS)
From enrollment to the end of treatment at 10:14 days
blood perfusion.
Time Frame: From enrollment to the end of treatment at 10:14days.
effect of FREMS on blood perfusion by duplex.
From enrollment to the end of treatment at 10:14days.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
