Effects of acupuncture on pain and function in patients with subacromial impingement syndrome: A randomized sham-controlled trial.

Background: Subacromial impingement syndrome (SIS) is the most common cause of shoulder pain. Acupuncture is a traditional medicine that is effective on pain. This study aimed to evaluate the effect of acupuncture treatment on pain, function, range of motion (ROM) and quality of life compared to sham acupuncture in patients diagnosed with SIS. Methods: A randomized, prospective, double-blinded, sham-controlled trial was conducted. In acupuncture group 40 participants received acupuncture treatment plus exercise therapy while in control group 40 participants received sham acupuncture plus exercise therapy. Primary outcomes included pain-rest, activity and night pain. Secondary outcomes included function [Shoulder Pain and Disability Index (SPADI) and The Disabilities of the Arm, Shoulder and Hand Score (Quick DASH)], ROM, and quality of life [The Western Ontario Rotator Cuff Index (WORC)] in patients with SIS. Results: Both groups had significant improvements for pain-rest, activity night pain scores, SPADI, Quick DASH and WORC after treatment and at the first month follow-up. Significant improvements were recorded in the acupuncture group for all ROM after treatment and at the first month follow-up while in control group only in passive internal rotation. Acupuncture group had better improvements for Quick DASH, WORC and all ROM parameters after the treatment, as well as for all parameters except pain-night and passive flexion at the first month follow-up. Conclusion: This study suggest that acupuncture treatment is a safe, effective and non-invasive treatment option in patients with SIS. Trial registration: The study protocol is registered at clinicaltrials.gov (NCT05794633).

Comparison of the effects of duloxetine and pregabalin on pain and associated factors in patients with knee osteoarthritis.

OBJECTIVES: This study aimed to investigate the effects of duloxetine and pregabalin primarily on pain and functional status in patients with knee osteoarthritis and secondarily on quality of life, depression, anxiety, and sleep disturbance. METHODS: A total of 66 patients with knee osteoarthritis were randomized to use duloxetine or pregabalin. Patients were evaluated by Visual Analog Scale, Neuropathic Pain Diagnostic Questionnaire, Western Ontario and McMaster University Osteoarthritis Index, Short Form-36, Beck Depression Inventory, Beck Anxiety Inventory, and Pittsburg Sleep Quality Index before the treatment and after 4 and 12 weeks of treatment. RESULTS: Improvements occurred in Visual Analog Scale, Neuropathic Pain Diagnostic Questionnaire, Western Ontario and McMaster University Osteoarthritis Index, Short Form-36 (with an exception of the mental health subgroup scores in duloxetine-treated group), Beck Depression Inventory, and Beck Anxiety Inventory scores in both groups from 4 weeks after baseline. Pittsburg Sleep Quality Index total scores and SF-36 mental health subgroup scores started to improve on the 4th and 12th weeks in pregabalin- and duloxetine-treated groups, respectively. CONCLUSION: Osteoarthritis pain, a complex outcome with nociceptive and neuropathic components, leads to central sensitization in a chronic phase. Using centrally acting drugs in the control of pain and associated symptoms would increase the probability of treatment success.

Effectiveness of Repetitive Transcranial Magnetic Stimulation in Patients With Failed Back Surgery Syndrome: A Double-Blind Randomized Placebo-Controlled Study.

BACKGROUND: Failed back surgery syndrome (FBSS) is the term of persistent back and/or leg pain after lumbar surgery. Repetitive transcranial magnetic stimulation (r-TMS) is a technique that allows noninvasive and relatively painless stimulation of cerebral cortex. It can reduce the experience of chronic pain by producing the small electrical currents in the cortex via magnetic field. OBJECTIVES: The aim of this study is to determine the effectiveness of r-TMS treatment on patients with FBSS. STUDY DESIGN: A double-blind, randomized, placebo-controlled trial. SETTING: The Physical Medicine and Rehabilitation Clinic of Istanbul Fatih Sultan Mehmet Training and Research Hospital, Istanbul, Turkey. METHODS: In this double-blinded, randomized, placebo-controlled trial, 20 patients (aged 34-65 years) clinically diagnosed as FBSS who had a history of surgery for lumbar disc herniation with persistent back and leg pain were reviewed. Only patients with no root compression and/or spinal stenosis in postoperative magnetic resonance imaging of lumbar spine were included. Patients were randomly assigned to r-TMS (n:10) and sham (n:10) groups. Patients in the r-TMS group received 5 Hz of r-TMS as a 20-minute (1,000 pulses) daily session, 5 days per week, for a total of 10 sessions. r-TMS was applied with MagVenture device (MagPro X100, Denmark, 2009) and figure 8 coil (MMC 140 parabolic, MagVenture). Control group received sham r-TMS with the same protocol. Each patient was evaluated at baseline, days 5 and 10 of treatment, and 1 and 3 months after treatment. Visual Analog Scale (VAS), DN4 (Douleur Neuropathique en 4 Questions), Oswestry Disability Index (ODI), Beck Depression Inventory (BDI), and the Pittsburgh Sleep Quality Index (PSQI) were used for evaluation. RESULTS: There were no statistically significant differences between the groups for age, gender, number of surgeries, pain duration, working status, and drug usage. Significant improvements were achieved in DN4, ODI, BDI, and PSQI scores in the r-TMS group in comparison to the sham group. Both groups displayed improvements in VAS scores, whereas improvement in the sham group was limited to the first month. Achieved improvements in the r-TMS group in terms of VAS, DN4, ODI, BDI, and PSQI scores were sustained at the third month. LIMITATIONS: The limited number of patients and the short follow-up periods are the main limitations of our study. Further placebo-controlled studies with longer follow-up periods and greater number of cases would be beneficial for examining r-TMS application as a new treatment option in patients with FBSS. CONCLUSIONS: r-TMS might be an effective alternative treatment in patients with FBSS, further studies with larger groups are needed.

The effectiveness of ultrasound treatment for the management of knee osteoarthritis: a randomized, placebo-controlled, double-blind study.

BACKGROUND/AIM: A randomized, placebo-controlled, double-blind study was designed to investigate the effectiveness of ultrasound therapy in primary knee osteoarthritis. MATERIALS AND METHODS: Ninety patients between 40 and 65 years of age having grade 2 and 3 bilateral knee osteoarthritis enrolled in the study were randomly assigned into 3 groups: continuous ultrasound, pulsed ultrasound, and placebo ultrasound. All patients were given a home exercise program. Patients were evaluated at baseline, at the end of the treatment, and at the second month after the treatment by a range of motion measurement, visual analog scale, Lequesne index for knee osteoarthritis, and Short Form-36 quality of life scale. RESULTS: The increase in the knee range of motion was similar in both ultrasound groups, while the change in the placebo group was not statistically significant. Visual analog scale scores and Lequesne scores of the placebo group at the second month were significantly greater than both ultrasound groups' scores (P < 0.01 and P < 0.05, respectively). CONCLUSION: Significant improvements in terms of pain, function, and quality of life scales were noted in both ultrasound groups in comparison with the placebo group. No statistically significant difference was found in terms of efficacy between the continuous and pulsed ultrasound.
