Stretching Exercises Versus Thermotherapy on Restless Legs Syndrome Symptoms

a quasi-experimental study was carried out at the antenatal outpatient clinic of XXXX. A sample of 60 pregnant women was randomly assigned to two groups. One group was instructed to perform stretching exercises daily for one week, and the other group applied thermotherapy. They rated their RLS symptoms, pain level, and sleep quality at baseline and after receiving interventions.

A convenience sampling of 60 pregnant women who fulfilled the following inclusion criteria was recruited: suffering from RLS according to the IRLSSG criteria during the third-trimester of a singleton pregnancy; rated restlessness severity greater than ten on the RLS Rating Scale, and compliant with an iron supplement. While, women who had a high-risk pregnancy, e.g., preeclampsia, diabetes, and placenta previa as well as had leg cramps, periodic limb movement disorder, leg edema, myalgia, peripheral neuropathy, leg injuries, and anxiety were excluded from the study.

Initially, the researchers approached the pregnant women of both groups in the waiting area of the antenatal clinic, established rapport, and collected the socio-demographic data and current pregnancy profile, Moreover, baseline RLS symptoms severity, pain, and women's sleep quality were assessed.

Interventions

For the stretching exercises group; the researchers explained to the women how to perform the stretching exercises through different visual materials like videos & pictures, provided a demonstration of each step, and emphasized that they could perform this exercise at any comfortable position, standing, sitting, or dorsal.

For the thermotherapy group, women were instructed to warm the water to 43-47 C° using a water thermometer or test it with the inner aspect of their wrists. They are also advised to avoid using too hot or too cold water. Then immerse their legs for 20 minutes in the warm water at a height where the water level can reach their knees. The researchers emphasized that the procedure should be done every night for one week.

For both groups, the intensity of RLS and pain severity of pregnant women of the two groups were reassessed after the first session.
