Psychological treatments of dysmenorrhea: differential effectiveness for spasmodics and congestives. Randomised controlled trial of biofeedback training in persistent encopresis with anismus. Spinal manipulative therapy versus a low force mimic maneuver for women with primary dysmenorrhea: a randomized, observer-blinded, clinical trial. A randomised controlled trial of the outcome of health assessment of people aged 75 years and over. Randomized controlled trial of cognitive behaviour therapy for repeated consultations for medically unexplained complaints: a feasibility study in Sri Lanka.
Two studies are reported, examining the effectiveness of psychological treatments for dysmenorrhea. In Experiment 1, 33 women with spasmodic dysmenorrhea were treated with relaxation alone, or relaxation plus imagery, or assigned to a waiting-list control condition; and 29 women with congestive dysmenorrhea were treated with relaxation alone, or assigned to a waiting-list control condition. In Experiment 2, 18 additional congestives were treated with a coping skills package, or this package plus relaxation; these two groups were compared with the two congestive groups from Experiment 1. The dependent measures were reports of symptom severity, general discomfort, resting time, and medication use. Consistent with the literature, the main findings of the present studies are: (a) relaxation training (alone or with imagery) effectively reduces resting time for spasmodics; and (b) none of the treatments was shown to be effective for congestive sufferers. Paradoxical external anal sphincter contraction during attempted defecation (anismus) is thought to be an important contributor to chronic faecal retention and encopresis in children. Biofeedback training can be used to teach children to abolish this abnormal contraction.
                A randomised controlled trial in medical treatment resistant and/or treatment dependent children with anismus using surface electromyographic (EMG) biofeedback training to determine whether such training produces sustained faecal continence. Up to four sessions of biofeedback training were conducted at weekly intervals for each patient. Anorectal manometry was performed before randomisation and six months later. Parents of patients completed the "child behaviour checklist" (CBCL) before randomisation and at follow up.
                Sixty eight children underwent anorectal manometry and EMG. Of these, 29 had anismus (ages 4-14 years) and were randomised to either EMG biofeedback training and conventional medical treatment (BFT) (n = 14) or to conventional medical treatment alone (n = 15). All but one child were able to learn relaxation of the external anal sphincter on attempted defecation. At six months' follow up, laxative free remission had been sustained in two of 14 patients in the BFT group and in two of 15 controls (95% confidence interval (CI) on difference, -24% to 26%). Remission or improvement occurred in four of 14 patients in the BFT group and six of 15 controls (95% CI on difference, -46% to 23%). Of subjects available for repeat anorectal manometry and EMG at six months, six of 13 in the BFT group still demonstrated anismus v 11 of 13 controls (95% CI on difference, -75% to -1%). Of the four patients in full remission at six months, only one (in the BFT group) did not exhibit anismus. Rectal hyposensitivity was not associated with remission or improvement in either of the groups. Mean CBCL total behaviour problem scores were not significantly different between the BFT and control groups, but there was a significant improvement in CBCL school scale scores in the BFT group, and this improvement was significantly greater than that seen in the control group.
                The result of this study, together with those reported in other controlled trials, argues against using biofeedback training in children with encopresis. Non-drug therapies for women with primary dysmenorrhea are primarily based on anecdotal evidence and small-scale clinical studies. This randomized, observer-blinded, clinical trial evaluated the efficacy of spinal manipulative therapy (SMT) in the treatment of women with primary dysmenorrhea. Women were recruited from the Chicago metropolitan area and evaluated for inclusion through four screening levels. One hundred thirty eight women, ages 18-45, with primary dysmenorrhea diagnosed by participating gynecologists, were randomly assigned to either SMT or a low-force mimic (LFM) maneuver. No treatment occurred at menstrual cycle 1. Treatment for both groups took place on day 1 of cycles 2, 3 and 4, and prophylactic treatment of three visits took place during the 7 days before cycles 3 and 4. Main outcome measures were the Visual Analog Scale (VAS) and plasma concentration of the prostaglandin F2alpha metabolite, 15-keto-13,14-dihydro-prostaglandin F2alpha (KDPGF2alpha), measured 15 min before treatment and 60 min after treatment on day 1 of four consecutive menstrual cycles. The Moos' Menstrual Distress Questionnaire (MDQ) was also administered after treatment on day 1 of each cycle. At cycle 2, the post-treatment VAS scores decreased for both groups, with no statistically significant difference in pre- to post-treatment scores between the two groups (P = 0.44). The changes in pre- to post-treatment KDPGF2alpha levels were not statistically different between the SMT and LFM groups (P = 0.15). No treatment effects were detected over the three cycles for VAS, KDPGF2alpha or MDQ (P = 0.65, P = 0.61 and P = 0.78, respectively). However, there were statistically significant linear time effects for VAS (P = 0.008), MDQ (P < 0.001), and borderline significance for KDPGF2alpha (P = 0.054); these decreases were not considered clinically meaningful. The LFM maneuver used in this study was designed to act as a 'placebo-like' control treatment in comparison with SMT. Although it is possible that the trial did not continue long enough for any placebo effect of the LFM to wash out, it seems more likely that this maneuver was indistinguishable from SMT. Therefore, the postulated superior benefit of high-velocity, short-lever, low-amplitude, high-force spinal manipulation to a low-force maneuver is not supported by the results of this study. 1999 International Association for the Study of Pain. To measure the outcomes of a health assessment, conducted by a nurse, of people aged 75 years and older (75+HA) living independently in their own homes.
                Randomised controlled trial (RCT).
                A convenience sample of six general practices within the Adelaide Western Division of General Practice (AWDGP). A random sample of 100 participants was drawn from practice age-sex registers. Data were collected in initial visits between 1 August 1998 and February 1999, then in follow-up visits one year later.
                Participants were aged 75 years and over on 1 August 1998 and living independently in the community. 145 eligible patients were invited to join the study, and 100 of these consented to enrol (69%).
                A 75+HA conducted in the participant's home by a nurse and reported to their usual general practitioner.
                Primary: number of problems in each group; number of participants with problems; and mortality. Secondary: physical function; psychological (including cognitive) function; falls; and admission to institution.
                There were no significant differences between the control and intervention groups at follow-up in the number of problems, the number of participants with problems, or mortality. In the intervention group, there was significant improvement in self-rated health, geriatric depression score (GDS 15), and number of falls.
                This RCT has not demonstrated improvement in health status of the intervention group which received a 75+HA compared with a control group left to usual care. Research on the management and the outcome of treatment of medically unexplained symptoms is very limited. Development of simple but effective techniques for treatment and demonstration of their effectiveness when applied in primary health care are needed.
                A randomized controlled trial was carried out with follow-up assessments at 3 months after baseline assessments using the Short Explanatory Model Interview (SEMI), General Health Questionnaire (GHQ-30), Bradford Somatic Inventory (BSI) and patient satisfaction on a visual analogue scale. The study was carried out in a general out-patient clinic in Sri Lanka. The intervention group received six, 30 min sessions based on the principles of cognitive behavioural therapy over a period of 3 months. The control group received standard clinical care.
                Eighty patients out of the 110 patients referred, were eligible. Sixty-eight were randomly allocated equally to the control and treatment groups. All 34 in the treatment group accepted the treatment offer and 22 completed between three and six sessions. At 3 months, 24 in the treatment and 21 in the control group completed follow-up assessments. Intention-to-treat analysis revealed significant differences in mean scores of outcome measures (adjusted for baseline scores) between control and intervention groups respectively--complaints 6.1 and 3.8 (P = 0.001), GHQ 10.4 and 6.3 (P = 0.04), BSI score 15.6 and 132 (P < 0-01), visits 7.9 and 3.1 (P = 0.004).
                Intervention based on cognitive behavioural therapy is feasible and acceptable to patients with medically unexplained symptoms from a general out-patients clinic in Sri Lanka. It had a significant effective in reducing symptoms, visits and distress, and in increasing patient satisfaction.
There is some evidence from five RCTs that behavioural interventions may be effective for dysmenorrhoea. However results should be viewed with caution as they varied greatly between trials due to inconsistency in the reporting of data, small trial size, poor methodological quality and age of the trials.
