Abdominal massage for the alleviation of symptoms of constipation in people with Parkinson's: a randomised controlled pilot study.

BACKGROUND: constipation is one of the most common non-motor features of Parkinson's affecting up to 90% of patients. In severe cases, it can lead to hospitalisation and is usually managed with laxatives which in themselves can lead to side effects. Abdominal massage has been used as adjunct in the management of constipation in various populations, but not in those with Parkinson's. OBJECTIVE: the primary objective was to test the recruitment, retention and the appropriateness of the intervention methods and outcome measures. METHODS: thirty-two patients with Parkinson's were recruited from three movement disorder clinics and were randomised to receive either 6 weeks of daily abdominal massage plus lifestyle advice on managing constipation (Intervention Group, n = 16) or lifestyle advice (Control Group, n = 16). Data were collected prior to group allocation (Baseline), at Week 6 (following intervention) and 4 weeks later (Week 10). Outcome tools included the Gastrointestinal Rating Scale and a bowel diary. RESULTS: constipation has a negative impact on quality of life. The study recruited to target, retention was high and adherence to the study processes was good. The massage was undertaken as recommended during the 6 weeks of intervention with 50% continuing with the massage at 10 weeks. Participants in both groups demonstrated an improvement in symptoms, although this was not significantly different between the groups. CONCLUSION: abdominal massage, as an adjunct to management of constipation, offers an acceptable and potentially beneficial intervention to patients with Parkinson's.

Pelvic floor muscle training as an adjunct to prolapse surgery: a randomised feasibility study.

INTRODUCTION AND HYPOTHESIS: There is evidence that in nonsurgical populations, pelvic floor muscle training (PFMT) and lifestyle advice improves symptoms and stage of pelvic organ prolapse (POP). Some women, however, require surgery, after which de novo symptoms can develop or additional surgery is required due to recurrence. Robust evidence is required as to the benefit of perioperative PFMT in the postsurgery reduction of symptoms and POP recurrence. The aim of this study was to assess the feasibility of and collect pilot data to inform sample size (SS) calculation for a multicentre randomised controlled trial (RCT) of perioperative PFMT following surgical intervention for POP. METHODS: Fifty-seven participants were recruited and randomised to a treatment group (one pre and six postoperative PFMT sessions) or a control group (usual care). The primary outcome measure was the Pelvic Organ Prolapse Symptom Score (POP-SS) at 12 months; secondary outcome measures included measurement of prolapse, the pelvic floor and questionnaires relating to urinary and bowel incontinence. All outcomes were measured at 0, 6 and 12 months. RESULTS: Information on recruitment, retention and appropriateness of outcome measures for a definitive trial was gathered, and data enabled us to undertake an SS calculation. When compared with the control group (n = 29), benefits to the intervention group (n = 28) were observed in terms of fewer prolapse symptoms at 12 months [mean difference 3.94; 95 % confidence interval (CI) 1.35-6.75; t = 3.24, p = 0.006]; however, these results must be viewed with caution due to possible selection bias. CONCLUSION: With modifications to design identified in this pilot study, a multicentre RCT is feasible.

Depression and anxiety related subtypes in Parkinson's disease.

BACKGROUND: Depression and anxiety are common in Parkinson's disease (PD) and although clinically important remain poorly understood and managed. To date, research has tended to treat depression and anxiety as distinct phenomena. There is growing evidence for heterogeneity in PD in the motor and cognitive domains, with implications for pathophysiology and outcome. Similar heterogeneity may exist in the domain of depression and anxiety. OBJECTIVE: To identify the main anxiety and depression related subtype(s) in PD and their associated demographic and clinical features. METHODS: A sample of 513 patients with PD received a detailed assessment of depression and anxiety related symptomatology. Latent Class Analysis (LCA) was used to identify putative depression and anxiety related subtypes. Results LCA identified four classes, two interpretable as 'anxiety related': one anxiety alone (22.0%) and the other anxiety coexisting with prominent depressive symptoms (8.6%). A third subtype (9%) showed a prominent depressive profile only without significant anxiety. The final class (60.4%) showed a low probability of prominent affective symptoms. The validity of the four classes was supported by distinct patterns of association with important demographic and clinical variables. CONCLUSION: Depression in PD may manifest in two clinical phenotypes, one 'anxious-depressed' and the other 'depressed'. However, a further large proportion of patients can have relatively isolated anxiety. Further study of these putative phenotypes may identify important differences in pathophysiology and other aetiologically important factors and focus research on developing more targeted and effective treatment.

A semi-structured interview to assess visual hallucinations in older people.

OBJECTIVE: Visual hallucinations are under-reported by patients and are often undiscovered by health professionals. There is no gold standard available to assess hallucinations. Our objective was to develop a reliable, valid, semi-structured interview for identifying and assessing visual hallucinations in older people with eye disease and cognitive impairment. METHODS: We piloted the North-East Visual Hallucinations Interview (NEVHI) in 80 older people with visual and/or cognitive impairment (patient group) and 34 older people without known risks of hallucinations (control group). The informants of 11 patients were interviewed separately. We established face validity, content validity, criterion validity, inter-rater agreement and the internal consistency of the NEVHI, and assessed the factor structure for questions evaluating emotions, cognitions, and behaviours associated with hallucinations. RESULTS: Recurrent visual hallucinations were common in the patient group (68.8%) and absent in controls (0%). The criterion, face and content validities were good and the internal consistency of screening questions for hallucinations was high (Cronbach alpha: 0.71). The inter-rater agreements for simple and complex hallucinations were good (Kappa 0.72 and 0.83, respectively). Four factors associated with experiencing hallucinations (perceived control, pleasantness, distress and awareness) were identified and explained a total variance of 73%. Informants gave more 'don't know answers' than patients throughout the interview (p = 0.008), especially to questions evaluating cognitions and emotions associated with hallucinations (p = 0.02). CONCLUSIONS: NEVHI is a comprehensive assessment tool, helpful to identify the presence of visual hallucinations and to quantify cognitions, emotions and behaviours associated with hallucinations.
