Restorative Effect of Vitamin D Deficiency on Knee Pain and Quadriceps Muscle Strength in Knee Osteoarthritis.
Both vitamin D deficiency and quadriceps muscle weakness are associated with knee osteoarthritis (KOA) and pain. The aim of this study was to determine the restorative effect of vitamin D deficiency on pain and quadriceps muscle strength in knee osteoarthritis. Patients with KOA aged ≥30 years, the presence of knee pain for at least one month or longer and serum 25-hydroxyvitamin (25-OHD) deficiencies were recruited in the study. ⋯ Serum 25-OHD reached to sufficient levels in all except one patient. At the end of the study period, serum 25-OHD and quadriceps muscle strength increased significantly as compared with baseline (P=0.007 and P=0.002, respectively), whereas knee pain decreased significantly based on Western Ontario and McMaster University Osteoarthritis index (P=0.001)as well as visual analogue scale scores (P=0.001). These findings indicated that correction of vitamin D deficiency in patients with KOA exerts a significant favorable effect on quadriceps muscle strength and knee pain.

Randomized Controlled TrialThe Effect of Foot Reflexology on Anxiety, Pain, and Outcomes of the Labor in Primigravida Women.
Reflexology is a technique used widely as one of non-pharmacological pain management techniques. The present study aimed to review and determine the effect of foot reflexology on anxiety, pain and outcomes of the labor in primigravida women. This clinical trial study was conducted on 80 primigravida mothers who were divided randomly into an intervention group (Foot reflexology applied for 40 min, n=40) and control group (n=40). ⋯ Furthermore, a significant difference was observed between two groups in terms of the frequency distribution of the type of labor and Apgar score (P<0.001). Results of this study show that reflexology reduces labor pain intensity, duration of labor, anxiety, frequency distribution of natural delivery and increases Apgar scores. Using this non-invasive technique, obstetricians can achieve, to some extent, to one of the most important goals of midwifery as pain relief and reducing anxiety during labor and encourage the mothers to have a vaginal delivery.
