Brief summary

Purpose:The aim of the study was to investigate the effectiveness of interferential current therapy on salivary gland function in Primary Sjogren's Syndrome (pSS). Methods:Thirty six pSS were included in the study. Patients were randomly divided into 2 groups (Group 1 (treatment group) n=18; Group II (placebo group) n=18). Salivary flow rate measurement (SFRM), Oral Health-Related Quality of Life-United Kingdom Questionnaire (OHRQOL-UK), Oral Health Impact Profile-14 (OHIP-14), Health Assessment Questionnaire (HAQ), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI) and Short Form-36 (SF-36) were used for evaluation. All evaluations were done pre-, posttreatment, at 3. month, at 6. month and at 9. month. Clinical pilates exercises and interferential current therapy were applied to Group I while clinical pilates exercises and interferential current therapy as placebo was applied to Group II. All treatments were given three times a week for 8 weeks.

Interventions

OTHERClinical pilates exercises +Interferential current therapy (real current)

All treatments were given three times a week for 8 weeks. The current intensity was determined as the mA CC level that the patient felt at the maximum but did not feel any discomfort.

OTHERClinical pilates exercises+ Interferential current therapy (Placebo current)

All treatments were given three times a week for 8 weeks. The current intensity was set to 0.1 mA CC (necessary for the machine to work)

Design outcomes

Primary

MeasureTime frameDescription
Salivary Flow Rate Measurement15 minutes
Oral Health Impact Profile-145 minutesTotal score is between 0 and 56. A high score indicates that the quality of life related to oral and dental health decreases.
Oral Health-Related Quality of Life-United Kingdom Questionnaire5 minutesTotal scores range from 16 to 80. A high score indicates that the quality of life related to oral and dental health is high.

Secondary

MeasureTime frameDescription
Short Form-3610 minutesEach subscale has a score between 0 and 100, and a high score means the good quality of life
Health Assessment Questionnaire5 minutesThe total score is between 0 and 3. A higher score indicates greater disability.
Pittsburgh Sleep Quality Index7 minutesTotal score ranges from 0 to 21. High scores indicate poor sleep quality.
Beck Depression Inventory7 minutesTotal summed score range of 0-63. High score means high depression
Beck Anxiety Inventory7 minutesThe score range is 0-63. A high score indicates a high level of anxiety.
