Study summary

Between available therapies for dry mouth is electrostimulation. Using an extra-oral device like TENS - which result in a statistically significant - increases the quantity of whole salivary flow rate production in xerostomia patients. The use of acupuncture as an alternative treatment modality for xerostomia has been documented in the Western medical field since the 1980s. Observational studies have demonstrated that acupuncture treatment may increase salivary flow in healthy volunteers.

Read the detailed description

It is possible that an increase of the blood fiux in the salivary glands may be one of the mechanisms behind the positive effect of acupuncture on the metabolism of the salivary glands, which leads to an increase of the salivary fiow.

Transcutaneous electric nerve stimulation (TENS) is a non-pharmacological and well known physical therapy modality which is widely for the acute and chronic pain management.

Electrostimulation using an extraoral device like TENS on parotid gland results in a statistically significant increase in the quantity of whole saliva flow rate production.

Starting a prevention program as early as possible considering the most practical, cost effective and efficient treatments with the best risk-benefit ratio will help to diminish dry mouth symptoms and sequelae.

Study population

100 healthy volunteers above 18 years from both sexes randomly assigned to TENS or electro-acupuncture group.

  • (TENS group): Volunteers in this group (n=50) will receive only one session of 5-minute extra-oral TENS applied on bilateral parotid gland with 50 HZ frequency and pulse duration 250microsecons
  • (Electro-acupuncture group): Volunteers in this group (n=50) will receive only one session of 5-minute electro-acupuncture on local acu-points St4 and St 7 bilateraly with 2 HZ frequency.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

What researchers measure

Primary outcomes

  1. salivary flow rate

    It is estimated as follow: * By dividing whole resting salivary volume on five minute collection period , thus whole resting salivary flow rate (ml/minute) is obtained (baseline). * Dividing stimulated salivary volume - collected during TENS application - on five minute collection period, thus stimulated salivary flow rate (ml/minute) is obtained. * Assessing improvement is done by comparing stimulated with whole resting salivary flow rate. Any increase in salivary rate will be considered an improvement

    Time frame: during the five-minute TENS session.
