Researchers from the University of British Columbia, University of Toronto, Dalhousie University and the University of Calgary studied the efficacy of light treatment, as a sole therapy and in combination with fluoxetine hydrochloride (Prozac), compared with a sham-placebo condition in adults with non-seasonal major depressive disorder (MDD).
They implemented a randomized, double-blind, placebo- and sham-controlled, 8-week trial with 122 adults (aged 19-60 years) with MDD of at least moderate severity, in outpatient psychiatry clinics in academic medical centers across Canada.
Researchers from Freie University in Berlin, Germany, investigated the efficacy of a cognitive behavioral internet-based intervention for war-traumatized Arab patients, to see if an e-treatment for posttraumatic stress that's been shown to be useful in western countries, has applicability to this population.
A total of 159 individuals diagnosed with PTSD participated in a parallel group randomized trial. Participants were randomly allocated by a computer-generated sequence to a treatment group (n=79) or a waiting list control group (n=80).
The treatment group received 2 weekly 45-minute cognitive behavioral interventions via the internet over a 5-week period (10 sessions in total). The primary outcome was recovery from posttraumatic stress symptoms.
This Chinese study explores the impacts and efficacy of acupuncture and motor imagery on fine movement of an upper extremity for stroke patients in the flaccid paralysis stage of recovery.
Sixty-two cases of flaccid, upper extremity paralysis were randomized into an observation group (30 cases) and a control group (32 cases).
The control group was treated with conventional western medication plus passive movement of the extremity. Additionally, penetrating acupuncture was applied. The needles were retained for 30 min.
Researchers from National University of Singapore conducted a randomized, four-arm design study with 100 veterans suffering from chronic lower back pain. The goal was to test the efficacy of hypnosis for alleviating lower back pain, as well as learn about the minimum dose required to produce meaningful benefits.
Additionally, the role of home practice was assessed as well as how well improvements were sustained beyond 3 months.
Researchers from Walden University in Minneapolis conducted a randomized, controlled study to assess the impact of a yoga intervention on the psychological health of older adults.
Subjects were 98 older adults, ages 65 to 92, randomly assigned to 6 weeks of either chair yoga, chair exercise or a control group condition. They were assessed pre-and post-intervention, and at one month follow-up on their anger, anxiety, depression, morale and self-efficacy.
In a phone interview survey, researchers from Bastyr University assessed the prevalence and use of integrative medicine techniques (or CAM – complementary and alternative medicine) by hospices in the state of Washington.
The response rate was 100%. Results indicated that 86% of Washington State hospices offered CAM services to their patients.
Researchers from Harvard and McGill Universities performed a systematic review of studies investigating the impact of mindfulness-based stress reduction (MBSR) on stress and anxiety in healthy, nonclinical adults.
A total of 29 studies (n=2668) were included. Effect-size estimates suggested that MBSR is moderately effective in pre-post analyses (n=26; Hedge's g=.55; 95% CI [.44, .66], p<.00001) and in between-group analyses (n=18; Hedge's g=.53; 95% CI [.41, .64], p<.00001).
Outcomes were maintained at an average of 19 weeks of follow-up and the results suggest large effects on stress, moderate effects on anxiety, depression, distress, and quality of life, and small effects on burnout.
In this pre-test/ post-test pilot study, researchers from the Institute of Psychiatry, Psychology & Neuroscience at King's College in London, UK, compared the short term impact of a brief mindfulness training (n=19) to guided imagery relaxation (n=18) with patients suffering from acute depression.
Participants were introduced to either mindfulness or guided imagery/relaxation in a single session, and practiced daily over one week.
Researchers from Saint Clare Health Systems in Dover, New Jersey investigated the effectiveness of the "M" Technique of structured touch (M), compared with guided imagery and usual care, for the reduction of pain and anxiety in patients undergoing elective total knee or hip replacement surgery.
"M" is a registered method of structured touch using a set sequence and number of strokes, and a consistent level of pressure on hands and feet,
Researchers from Cyprus University of Technology and the University of Athens conducted a randomized, controlled study, testing the effectiveness of guided imagery and progressive muscle relaxation as stress reducing interventions in 236 patients with prostate and breast cancer who were being treated with chemotherapy.
Subjects were randomly assigned to either the control group or the intervention group (PMR and GI), and were observed for a total duration of 3 weeks. In total, 104 were randomized to the control group and 104 to the intervention group.
