Summary Background Pelvic organ prolapse is common and is strongly associated with childbirth and increasing age. Women with prolapse are often advised to do pelvic floor muscle exercises, but ...evidence supporting the benefits of such exercises is scarce. We aimed to establish the effectiveness of one-to-one individualised pelvic floor muscle training for reducing prolapse symptoms. Methods We did a parallel-group, multicentre, randomised controlled trial at 23 centres in the UK, one in New Zealand, and one in Australia, between June 22, 2007, and April 9, 2010. Female outpatients with newly-diagnosed, symptomatic stage I, II, or III prolapse were randomly assigned (1:1), by remote computer allocation with minimsation, to receive an individualised programme of pelvic floor muscle training or a prolapse lifestyle advice leaflet and no muscle training (control group). Outcome assessors, and investigators who were gynaecologists at trial sites, were masked to group allocation; the statistician was masked until after data analysis. Our primary endpoint was participants' self-report of prolapse symptoms at 12 months. Analysis was by intention-to-treat analysis. This trial is registered, number ISRCTN35911035. Findings 447 eligible patients were randomised to the intervention group (n=225) or the control group (n=222). 377 (84%) participants completed follow-up for questionnaires at 6 months and 295 (66%) for questionnaires at 12 months. Women in the intervention group reported fewer prolapse symptoms (ie, a significantly greater reduction in the pelvic organ prolapse symptom score POP-SS) at 12 months than those in the control group (mean reduction in POP-SS from baseline 3·77 SD 5·62 vs 2·09 5·39; adjusted difference 1·52, 95% CI 0·46–2·59; p=0·0053). Findings were robust to missing data. Eight adverse events (six vaginal symptoms, one case of back pain, and one case of abdominal pain) and one unexpected serious adverse event, all in women from the intervention group, were regarded as unrelated to the intervention or to participation in the study. Interpretation One-to-one pelvic floor muscle training for prolapse is effective for improvement of prolapse symptoms. Long-term benefits should be investigated, as should the effects in specific subgroups.

Summary Background Pelvic floor muscle training can reduce prolapse severity and symptoms in women seeking treatment. We aimed to assess whether this intervention could also be effective in secondary ...prevention of prolapse and the need for future treatment. Methods We did this multicentre, parallel-group, randomised controlled trial at three centres in New Zealand and the UK. Women from a longitudinal study of pelvic floor function after childbirth were potentially eligible for inclusion. Women of any age who had stage 1–3 prolapse, but had not sought treatment, were randomly assigned (1:1), via remote computer allocation, to receive either one-to-one pelvic floor muscle training (five physiotherapy appointments over 16 weeks, and annual review) plus Pilates-based pelvic floor muscle training classes and a DVD for home use (intervention group), or a prolapse lifestyle advice leaflet (control group). Randomisation was minimised by centre, parity (three or less vs more than three deliveries), prolapse stage (above the hymen vs at or beyond the hymen), and delivery method (any vaginal vs all caesarean sections). Women and intervention physiotherapists could not be masked to group allocation, but allocation was masked from data entry researchers and from the trial statistician until after database lock. The primary outcome was self-reported prolapse symptoms (Pelvic Organ Prolapse Symptom Score POP-SS) at 2 years. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov , number NCT01171846. Findings Between Dec 21, 2008, and Feb 24, 2010, in New Zealand, and Oct 27, 2010, and Sept 5, 2011, in the UK, we randomly assigned 414 women to the intervention group (n=207) or the control group (n=207). One participant in each group was excluded after randomisation, leaving 412 women for analysis. At baseline, 399 (97%) women had prolapse above or at the level of the hymen. The mean POP-SS score at 2 years was 3·2 (SD 3·4) in the intervention group versus 4·2 (SD 4·4) in the control group (adjusted mean difference −1·01, 95% CI −1·70 to −0·33; p=0·004). The mean symptom score stayed similar across time points in the control group, but decreased in the intervention group. Three adverse events were reported, all of which were in the intervention group (one women had a fall, one woman had a pain in her tail bone, and one woman had chest pain and shortness of breath). Interpretation Our study shows that pelvic floor muscle training leads to a small, but probably important, reduction in prolapse symptoms. This finding will be important for women and caregivers considering preventive strategies.

Introduction. Each year an estimated 30,000-45,000 UK individuals experience stroke-related dysarthria (impairment of movements required to produce speech). Many will experience persistent dysarthria ...long after discharge from stroke services. Although we have some insight into the impact of other communication impairments, we have very limited information on the impact of dysarthria on social participation.
Purpose. To explore the impact of dysarthria on social participation following stroke.
Methods. We report data from in-depth semi-structured interviews with 24 individuals with stroke-related dysarthria.
Results. Our findings suggest a complex association between the severity of an individual's dysarthria and the impact on their social participation. Participants' descriptions highlighted their experiences of social participation and isolation. We further suggest that, in some cases, the coping strategies adopted by the participants could be seen to further exacerbate this isolation. These results have important implications for the prioritisation, planning and delivery of therapeutic interventions for people with dysarthria.
Conclusions. The impact of stroke-related dysarthria transcends the physiological impairment to impact upon individuals' social participation, which is key to the process of rehabilitation. The development and evaluation of the effectiveness of an intervention that addresses these impacts is the next challenge for therapists and researchers working in this area.
Following stroke, rates of mood disorder are and remain high at five years (anxiety 34.4%; depression 23%). Structured mindfulness-based stress reduction (MBSR) courses are effective in a range of ...health conditions, but stroke survivors find adherence challenging. We aimed to adapt a standard MBSR course specifically for people affected by stroke.
We recruited stroke survivors and family members with symptoms of anxiety and/or depression to take part in a co-development study comprising two rounds of MBSR 'taster' sessions, followed by focus groups in which views were sought on the practices sampled. Data were collected in October 2017 and May 2018 and were analysed using framework analysis, informed adaptations to mindfulness materials and delivery.
Twenty-eight stroke survivors and seven family members participated. Nineteen (76%) stroke survivors had anxiety; 15 (60%) had depression. Five (71.4%) family members reported anxiety;
= 4 (57.1%) depression. Thirty participants attended the first round of taster sessions and focus groups; twenty (66%) the second and three (10%) were unable to attend either round. Framework analysis informed adaptations to course delivery, practices, and materials, ultimately resulting in a stroke-specific MBSR course, HEADS: UP (Helping Ease Anxiety and Depression after Stroke).
HEADS: UP may provide a feasible, appropriate, and meaningful self-management intervention to help alleviate symptoms of mood disorder.
Aims
To evaluate effectiveness of transcutaneous tibial nerve stimulation (TTNS) for treating adults with overactive bladder (OAB) of idiopathic or neurogenic origin, using a systematic review of the ...literature.
Methods
Systematic searches of four databases were undertaken between 1980 and 2017. Included studies investigated effects of TTNS on OAB. Study selection, data extraction, quality appraisal was performed by two independent reviewers. Narrative analysis was undertaken where meta‐analysis was not possible due to study heterogeneity. Meta‐analysis of RCTs was performed using a fixed effects model.
Results
Ten RCTs and three prospective cohort studies involving 629 participants were reviewed. Meta‐analysis of two trials comparing TTNS with sham showed mean reduction in total ICIQ Urinary Incontinence Short Form (ICIQ‐UI SF) associated with TTNS of −3.79 (95% CI −5.82, −1.76; P = 0.0003, I2 = 25%). Narrative review showed TTNS and antimuscarinic treatment were equally effective (four trials), TTNS provided greater benefit for OAB symptoms than behavioral interventions (two trials), tibial nerve, and sacral foramen stimulation were equally effective but combined stimulation was most effective (one trial). Significant improvements in OAB symptoms were reported by 48‐93% participants and UI cure rates of 25‐45%. No adverse events were reported.
Conclusions
Limited evidence is provided that TTNS is an effective, safe intervention for idiopathic OAB in adults and may be of benefit in those with neurogenic OAB. Further studies are essential to confirm these results as well as to determine efficacy and associated costs for specific patient groups, most effective stimulation dosage, duration of effect, and stimulation regimes for longer‐term maintenance.
AbstractObjectivesTo assess the clinical effectiveness of two speech and language therapy approaches versus no speech and language therapy for dysarthria in people with Parkinson’s ...disease.DesignPragmatic, UK based, multicentre, three arm, parallel group, unblinded, randomised controlled trial.SettingThe speech and language therapy interventions were delivered in outpatient or home settings between 26 September 2016 and 16 March 2020.Participants388 people with Parkinson’s disease and dysarthria.InterventionsParticipants were randomly assigned to one of three groups (1:1:1): 130 to Lee Silverman voice treatment (LSVT LOUD), 129 to NHS speech and language therapy, and 129 to no speech and language therapy. LSVT LOUD consisted of four, face-to-face or remote, 50 min sessions each week delivered over four weeks. Home based practice activities were set for up to 5-10 mins daily on treatment days and 15 mins twice daily on non-treatment days. Dosage for the NHS speech and language therapy was determined by the local therapist in response to the participants’ needs (estimated from prior research that NHS speech and language therapy participants would receive an average of one session per week over six to eight weeks). Local practices for NHS speech and language therapy were accepted, except for those within the LSVT LOUD protocol. Analyses were based on the intention to treat principle.Main outcome measuresThe primary outcome was total score at three months of self-reported voice handicap index.ResultsPeople who received LSVT LOUD reported lower voice handicap index scores at three months after randomisation than those who did not receive speech and language therapy (−8.0 points (99% confidence interval −13.3 to −2.6); P<0.001). No evidence suggests a difference in voice handicap index scores between NHS speech and language therapy and no speech and language therapy (1.7 points (−3.8 to 7.1); P=0.43). Patients in the LSVT LOUD group also reported lower voice handicap index scores than did those randomised to NHS speech and language therapy (−9.6 points (−14.9 to −4.4); P<0.001). 93 adverse events (predominately vocal strain) were reported in the LSVT LOUD group, 46 in the NHS speech and language therapy group, and none in the no speech and language therapy group. No serious adverse events were recorded.ConclusionsLSVT LOUD was more effective at reducing the participant reported impact of voice problems than was no speech and language therapy and NHS speech and language therapy. NHS speech and language therapy showed no evidence of benefit compared with no speech and language therapy.Trial registrationISRCTN registry ISRCTN12421382.
Background: Post-stroke dysarthria rehabilitation should consider social participation for people with dysarthria, but before this approach can be adopted, an understanding of the psychosocial impact ...of dysarthria is required. Despite the prevalence of dysarthria as a result of stroke, there is a paucity of research into this communication disorder, particularly studies that address the experiences of individuals. The available literature focuses mainly on the perceptions of others or includes groups of mixed aetiologies.
Aims: To investigate the beliefs and experiences of people with dysarthria as a result of stroke in relation to their speech disorder, and to explore the perceived physical, personal and psychosocial impacts of living with dysarthria.
Methods & Procedures: Participants for this qualitative study were recruited from twelve hospitals in Scotland that served both rural and urban populations and afforded opportunity for comparison. Semi-structured, in-depth interviews were carried out over a 12-month period with 24 individuals with varying severity of dysarthria following stroke. The interviews were orthographically transcribed and coded using the NVivo package, which also facilitated identification of patterns using the constant comparative method.
Outcomes & Results: The results of the study indicate that the effects of dysarthria following stroke extend beyond the physiological characteristics of the impairment. In turn, the resulting communication difficulties lead to changes in self-identity, relationships, social and emotional disruptions, and feelings of stigmatization or perceived stigmatization. The impact of dysarthria was found to be disproportionate to the physiological severity, with participants continually striving to get their speech back to 'normal'.
Conclusions & Implications: The findings provide insight into the psychosocial impact of dysarthria following stroke. Speech and language therapy interventions need to go beyond the speech impairment to address and promote psychosocial well being, reduce the likelihood of feelings of stigmatization and changes in self-identity, irrespective of the severity of dysarthria.
Successful recruitment of participants to any trial is central to its success. Trial results are routinely published, and recruitment is often cited to be slower and more difficult than anticipated. ...This article reflects on the methodological challenges of recruiting women with prolapse attending United Kingdom (UK) gynaecology outpatient clinics to a multi-centre randomised controlled trial (RCT) of physiotherapy, and the systems put in place in an attempt to address them.
Gynaecology outpatients with symptomatic prolapse were to be recruited over a 16-month period from 14 UK hospitals and one New Zealand hospital. Eligible women were informed about the trial by their gynaecologist and informed consent was obtained by the central trial office. Recruitment difficulties were encountered early on, and a number of strategies were employed to try to improve recruitment.
Some strategies were more successful than others and they differed in the resources required. Actions that facilitated recruitment included increasing recruiting centres to 23 UK and two international hospitals, good centre support, using processes embedded in clinical practice, and good communication between the trial office, collaborators and participants. Collaborator incentives, whereby staff involved received the benefit immediately, were more successful than a nominal monetary payment per woman randomised. Barriers to recruitment included fewer eligible women than anticipated, patient's preference to receive active treatment rather than allocation to the control group, lack of support staff and high staff turnover. Geographical variations in Primary Care Trust Research Management and Governance approval systems and general practitioner (GP) referral procedures also impacted negatively on recruitment.
Our article reflects on the methodological challenges of recruiting to a multi-centre RCT in a UK gynaecology setting. Effective interventions included increasing the number of recruiting centres and providing collaborator incentives. Barriers to recruitment included fewer eligible women than anticipated, patient's preference to be allocated to the treatment group, lack of support staff, and variations in approval systems and GP referral procedures. To improve the evidence base on clinical trial recruitment, trialists need to publish their experiences and lessons learned. Future RCTs should evaluate, where possible, the effect of strategies designed to improve recruitment and retention.
Current Controlled Trials ISRCTN35911035.
Objective: To explore the perceptions of people with stroke-related dysarthria in relation to the management and rehabilitation of dysarthria.
Design: Qualitative semi-structured interviews.
Setting: ...Community setting
Subjects: Twenty-four people with an acquired dysarthria as a result of a stroke in the previous three years. All were living at home at the time of the interview. None exhibited a co-existing impairment (for example, aphasia, apraxia or cognitive impairment) that might have contributed to their communicative experiences.
Results: Participants described the considerable efforts they made to maximize their communicative effectiveness prior to, and during, communicative interactions. Activities described included careful articulation and vocal projection as well as more inconspicuous strategies including pre-planning interactions, focused, effortful speech and word substitution. Communication was facilitated by a range of strategies including drafting, rehearsal, manoeuvring and ongoing monitoring and repair. Self-led speech rehabilitation activities were functionally based and often undertaken regularly. Some novel reading-aloud and speaking-aloud activities were described.
Conclusion: The quantity and nature of inconspicuous, internalized, cognitive activities people with dysarthria engage in to maximize their communicative effectiveness should be considered in evaluating the impact of dysarthria following stroke. Focusing upon externally observable characteristics alone is insufficient. Challenging, functionally relevant, patient-focused activities, materials and targets are more likely to be perceived by the patient as relevant and worthwhile and are thus more likely to ensure adherence to recommended rehabilitation activities.
Iontophoretic assessment of skin microvascular function is complicated by the occurrence of electrically induced hyperaemia, especially at the cathode. Studies were performed to identify means of ...reducing such effects. Skin vasodilator responses were measured using a laser Doppler imager that controlled iontophoretic current delivery. A novel feature involved monitoring voltage across the iontophoresis chambers. Comparison between responses to vehicle (distilled H(2)O), acetylcholine (ACh) and sodium nitroprusside (SNP) showed electrically induced hyperaemia at the cathode associated with the vehicle, whose time course overlapped with that of the SNP response. Voltage across the chambers containing drugs dissolved in H(2)O was significantly (p = 0.018, n = 7) lower than the voltage profile of H(2)O alone. H(2)O iontophoresis was associated with cathodal hyperaemic responses in most subjects, whereas a 0.5% NaCl vehicle produced lower voltages and eliminated this artefact. Voltage.time integral rather than charge was the prime determinant of electrically induced hyperaemic responses. No significant correlation was found between skin fold thickness and either calculated skin resistance (r(2) = 0.0002) or vascular response to ACh (r(2) = 0.13). Smaller chamber size led to higher voltages and greater electrically induced hyperaemic responses. These appear to be prostaglandin dependent as they were ablated by cyclooxygenase inhibition. Use of a low-resistance vehicle combined with larger chamber sizes and lower currents can prevent such artefacts, thereby increasing the robustness of this methodology for clinical assessment of endothelial function.
