Randomized Controlled Trial
Effects of electrical stimulation program on trunk muscle strength, functional capacity, quality of life, and depression in the patients with low back pain: a randomized controlled trial.
The aim of this clinical trial was to evaluate the effects of electrical stimulation (ES) program on trunk muscle strength, functional performance, quality of life (QOL) in the patients with chronic low back pain (CLBP). A total of 41 patients with definite CLBP were included in this study. These patients were randomized into two groups. ⋯ Except depression and social function, the improvements for all the parameters were better in the ES group than in the control group. We observed that ES program was very effective in improving QOL, functional performance and isometric strength. In conclusion, we can say that ES therapy provides comfortable life functions by improving muscle strength, functional performance and QOL.

Randomized Controlled Trial
The effects of pulsed electromagnetic fields in the treatment of knee osteoarthritis: a randomized, placebo-controlled trial.
In this study, we planned to investigate the effects of pulse electromagnetic field (PEMF) on pain relief and functional capacity of patients with knee osteoarthritis (OA). Fifty-five patients with knee OA were included in a randomized, placebo-controlled study. At the end of the therapy, there was statistically significant improvement in pain scores in both groups (P < 0.05). ⋯ However, we could not observe statistically significant differences in total of the scale between two groups (P > 0.05). Applying between-group analysis, we were unable to demonstrate a beneficial symptomatic effect of PEMF in the treatment of knee OA in all patients. Further studies using different types of magnetic devices, treatment protocols and patient populations are warranted to confirm the general efficacy of PEMF therapy in OA and other conditions.

Although properly treated, patients with Complex Regional Pain Syndrome type 1 (CRPS type 1) of upper limb may continue to have sequel signs and symptoms of the disease in long-term. The aim of this study is to analyse the effect of the sequel findings of CRPS type 1 on upper limb disability and quality of life. Thirty patients with CRPS type 1 of the upper extremity were re-evaluated for the sequel sign and symptoms of CRPS type 1 after 18 months (8-60 months). ⋯ The severity of the pain, and numbness of the hands were the factors causing disability. Pain caused reduced quality of life in physical functioning. In conclusion, prolonged follow-up period and efforts to improve sensory disturbances (especially pain) may reduce the upper extremity disability and reduced quality of life in CRPS type 1 patients.

The main goal of this project was to identify the presence of fibromyalgia (FM) subgroups using a simple and frequently used clinical tool, the Fibromyalgia Impact Questionnaire (FIQ). A total of 61 women diagnosed with FM participated in this study. FM subgroups were created by applying a hierarchical cluster analysis on selected items of the FIQ (pain, fatigue, morning tiredness, stiffness, anxiety and depressive symptoms). ⋯ FM-Type I was characterized by the lowest levels of anxiety, depressive and morning tiredness symptoms, while FM-Type II was characterized by elevated levels of pain, fatigue, morning tiredness, stiffness, anxiety and depressive symptoms. Both FM subgroups showed hyperalgesic responses to experimental pain. These results suggest that pain and stiffness are universal symptoms of the disorder but that psychological distress is a feature present only in some patients.

The aim of this study was to investigate whether functional polymorphisms in the promoter of matrix metalloproteinase-1 (MMP-1), MMP-2 and MMP-9 genes were associated with susceptibility to knee osteoarthritis in the Turkish population. The MMP-1 -1,607 1G/2G (rs1799750), MMP-2 -1,306 C/T (rs243865), and MMP-9 -1,562 C/T (rs3918242) polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism assay in 157 patients diagnosed with knee osteoarthritis based on the criteria of American College of Rheumatology and in 84 controls in Mersin, Turkey. Genotype distributions and allele frequencies of MMP-1, MMP-2, and MMP-9 gene polymorphisms were compared between the patients and controls. ⋯ In addition, 1G allele frequency of MMP-1 gene was higher in the patients than in the control group (P = 0.0001). The genotype distributions and allele frequencies of MMP-2 and MMP-9 gene polymorphisms did not differ between the osteoarthritis and the control groups (P > 0.05). These findings suggest that the -1,607 1G/2G polymorphism in the MMP-1 gene may contribute to susceptibility to knee osteoarthritis in the Turkish population.
