Somatosensory impairment after stroke: frequency of different deficits and their recovery

Objective: To investigate the frequency of somatosensory impairment in stroke patients within different somatosensory modalities and different body areas, and their recovery. Design: Prospective observational study. Setting: Two stroke rehabilitation units. Subjects: Seventy patients with a first stroke (36 men, 34 women; average age, 71, SD 10.00 years; average time since stroke onset, 15 days) were assessed on admission and two, four and six months after stroke. Interventions: Not applicable. Main measure: Nottingham Sensory Assessment. Results: Somatosensory impairment was common after stroke; 7—53% had impaired tactile sensations, 31—89% impaired stereognosis, and 34—64% impaired proprioception. When comparing somatosensory modalities within body areas the kappa values were low (kappa values <0.54). Recovery occurred over time, though not significantly in lower limb tactile sensations. Stroke severity was the main factor influencing initial somatosensory impairment, but accounted for a small amount of the variance (21—41%). Initial somatosensory impairment was significantly related to somatosensory ability at six months, accounting for 46—71% of the variance. Conclusions: Proprioception and stereognosis were more frequently impaired than tactile sensations. The different somatosensory modalities showed only slight agreement between impairment within the same body areas, suggesting that the modalities are independent of each other and all should be assessed. High agreements were found between different body areas for each somatosensory modality. Somatosensory impairment was associated with stroke severity, however low variance indicated other factors were involved.

A prospective study of cognitive tests to predict performance on a standardised road test in people with dementia

Previous work by Lincoln and colleagues produced a cognitive test battery for predicting safety to drive in people with dementia. The aim was to check the accuracy of this battery and assess whether it could be improved by shortening it, including additional cognitive tests, and a measure of previous driving.

Measuring fatigue in people with Multiple Sclerosis

Objective: To compare methods of assessing fatigue. Design: Cross sectional. Setting: Community. Subjects: Forty Multile Sclerosis (MS) patients and 20 healthy controls. Main outcome measures: Fatigue questionnaires, SDSA dot cancellation test, finger tapping test, TEA Lottery. Results: The MS patients had significantly higher levels of fatigue than the controls on the Task Induced Fatigue Scale, Fatigue Severity Scale and Fatigue Impact Scale. The Task Induced Fatigue Scale completed whilst imagining oneself driving and the Fatigue Assessment Instrument did not differentiate between MS patients and controls. Finger tapping differentiated between MS patients and controls but there was no significant difference between MS patients and controls on visual and auditory concentration tests. A factor analysis indicated that questionnaire measures of fatigue were inter-related but independent of objective test performance. Conclusions: Questionnaire measures can be used to assess fatigue in people with MS. The FSS differentiated MS patients from controls and is relatively short. It was therefore recommended for clinical use.

What Concerns Workers with Low Back Pain? Findings of a Qualitative Study of Patients Referred for Rehabilitation

Introduction Health and workplace strategies to address work loss and sickness absence due to low back pain are urgently required. A better understanding of the experiences of those struggling to stay at work with back pain may help clinicians and employers with their treatment and management approaches. Methods A qualitative approach using thematic analysis was used. Individual semi-structured interviews were conducted with a convenience sample of 25 low back pain patients who had been referred for multidisciplinary back pain rehabilitation. All were in employment and concerned about their ability to work due to low back pain. Initial codes were identified and refined through constant comparison of the transcribed interview scripts as data collection proceeded. Themes were finally identified and analysed by repeated study of the scripts and discussion with the research team. Findings Five main themes were identified: justifying back pain at work; concern about future ability to retain work; coping with flare-ups; reluctance to use medication; concern about sickness records. Conclusions In this study, workers with low back pain remained uncertain of how best to manage their condition in the workplace despite previous healthcare interventions and they were also concerned about the impact back pain might have on their job security and future work capacity. They were concerned about how back pain was viewed by their employers and co-workers and felt the need to justify their condition with a medical diagnosis and evidence. Clinicians and employers may need to address these issues in order to enable people to continue to work more confidently with back pain.

A study of interventions and related outcomes in a randomized controlled trial of occupational therapy and leisure therapy for community stroke patients

Objective: To undertake a detailed analysis of therapy provided in a multicentred randomized controlled trial of activities of daily living (ADL) and leisure (TOTAL), testing the hypothesis that specific interventions given in the trial affected specific aspects of outcome. Subjects: Three hundred and nine stroke patients who had been randomly allocated to receive either occupational therapy aimed at ADL activities (n = 156) or leisure (n = 153). Measures: Number, duration and type of activity undertaken per patient. Barthel Index, Extended Activities of Daily Living Scale (EADL) and Nottingham Leisure Questionnaire (NLQ) six months after entry to the study. Method: Activities that had been used in treatment were coded and categorized. Frequently used activities identified. These activities were matched to items from the six-month outcome measures. Patient independence in these outcome items was compared between the leisure and ADL groups. Results: Three hundred and nine therapy record forms were returned. Patients received a median of ten sessions with a median duration of 55 minutes. The ADL group received significantly more, mobility training, transfer training, cleaning, dressing, cooking and bathing training (chi-squared, p < 0.05). Sport, creative activities, games, hobbies, gardening, entertainment and shopping were used significantly more in the leisure group (chi-squared, p < 0.05) than the ADL group. Fifteen items from the outcome measures were identified as specific to these interventions. There were no statistically significant differences in outcome on these 15 items between the ADL and leisure groups (chi-squared, p > 0.05). Conclusions: We found no evidence that specific ADL or leisure interventions led to improvements in specific relevant outcomes. We believe that these findings should prompt a review of the relationship between process and outcome of occupational therapy.

Developing stroke-specific vocational rehabilitation: a soft systems analysis of current service provision

Abstract Purpose: This study aimed to clarify the existing service provision of stroke-specific vocational rehabilitation (VR) in one English county, in order to facilitate future service development. Method: Using soft systems methodology, services in Health, Social Care, Department of Work and Pensions, the voluntary and private sectors, which were identified as supporting return to work after stroke, were mapped using a mixed-methodology approach. Results: A lack of a sanctioned VR pathway meant access to support relied on brokered provision and tacit knowledge. The timing of an intervention was complex and there was a substantial degree of unmet need for mild stroke patients. VR was seen as “non-essential” due to competing commissioning priorities. Service providers from all sectors lacked training and cross-sector partnerships were tenuous and provider roles unclear. Conclusions: Stroke-specific VR should be delivered by an integrated, cross-sector multi-disciplinary team and integrated commissioning between health and other sectors is necessary. Although early intervention is important, support later on in the recovery process is also necessary. Service providers need adequate training to meet the needs of stroke survivors wishing to return to work and better awareness of best practice guidelines. Business cases which demonstrate the efficacy and cost-effectiveness of VR are vital. Implications for Rehabilitation The timeliness of a vocational rehabilitation (VR) intervention is complex; services need to be responsive to the changing needs of the stroke survivor throughout their recovery process and have better mechanisms to ensure re-entry into the stroke pathway is possible. Return to work is a recognised health outcome; health services need to develop better mechanisms for interagency/cross sector working and liaison with employers and not assume that VR is beyond their remit. Therapists and non-health service providers should receive sufficient training to meet the needs of stroke survivors wishing to return to work. Rehabilitation teams must decide how to implement national guidance within existing resources and what training is needed to deploy SSVR. The lack of a sanctioned pathway results in disorganised and patchy provision of VR for stroke survivors; mild stroke patients can fall through the net and receive little or no support. The journey back to work commences at the point of stroke. Mechanisms for identifying acute stroke survivors who were working at onset and for assessing the impact of the stroke on their work need to be put in place. The entire MDT has a role to play. In the absence of a VR specialist, even patients without obvious disability should be referred for ongoing rehabilitation with detailed work assessment and signposted to employment specialists e.g. disability employment advisors EARLY after stroke. Health-based VR interventions can influence work return and job retention. However, therapists must routinely measure work outcomes to inform their business case and be encouraged to demonstrate these outcomes to local commissioners. Commissioners should consider emerging evidence of early VR interventions on reduced length of stay, health and social care resource use and the wider health benefits of maintaining employment.

Return to Work after Traumatic Brain Injury: Recording, Measuring and Describing Occupational Therapy Intervention

Low post-injury employment rates indicate that returning to work is difficult following traumatic brain injury (TBI). Occupational therapists assist people with TBI to return to work, but rarely is their intervention described. This has hindered research into vocational rehabilitation. As no existing tool was identified for recording intervention, a proforma was developed for this study. Using best practice guidelines and a consensus of expert opinion, 15 categories of the vocational rehabilitation process were identified. Time spent on each category was recorded in 10-minute units after each occupational therapy session. The records of 21 participants who received occupational therapy focused on vocational rehabilitation were analysed. The proforma was quick and simple to use. The analysis showed that assessment, work preparation, employer involvement, education and dealing with issues of immediate concern to participants accounted for almost 85% of face-to-face intervention. It also showed that for every 1 hour of face-to-face contact, an additional 2 hours was required for liaison and travel. This study showed that there is potential for using a proforma for quantifying and describing occupational therapy. This is the basis for further work to enable meaningful comparisons with other services and use in future studies.

Improving the development, monitoring and reporting of stroke rehabilitation research: Consensus-based core recommendations from the Stroke Recovery and Rehabilitation Roundtable

Recent reviews have demonstrated that the quality of stroke rehabilitation research has continued to improve over the last four decades but despite this progress, there are still many barriers in moving the field forward. Rigorous development, monitoring and complete reporting of interventions in stroke trials are essential in providing rehabilitation evidence that is robust, meaningful and implementable. An international partnership of stroke rehabilitation experts committed to develop consensus-based core recommendations with a remit of addressing the issues identified as limiting stroke rehabilitation research in the areas of developing, monitoring and reporting stroke rehabilitation interventions. Work exploring each of the three areas took place via multiple teleconferences and a two-day meeting in Philadelphia in May 2016. A total of 15 recommendations were made. To validate the need for the recommendations, the group reviewed all stroke rehabilitation trials published in 2015 (n = 182 papers). Our review highlighted that the majority of publications did not clearly describe how interventions were developed or monitored during the trial. In particular, under-reporting of the theoretical rationale for the intervention and the components of the intervention call into question many interventions that have been evaluated for efficacy. More trials were found to have addressed the reporting of interventions recommendations than those related to development or monitoring. Nonetheless, the majority of reporting recommendations were still not adequately described. To progress the field of stroke rehabilitation research and to ensure stroke patients receive optimal evidence-based clinical care, we urge the research community to endorse and adopt our recommendations.

Commissioning vocational rehabilitation after stroke: Can the Cinderella services get to the ball? A qualitative study

Objective To understand the barriers and enablers to commissioning vocational rehabilitation (VR) after stroke. Methods Interviews with health and social care commissioners responsible for stroke services across three counties were conducted to explore their views on the barriers and enablers to commissioning VR. Transcripts were subjected to thematic analysis, and validity checked with members of the research team. Results The findings indicate that health commissioners have had to focus on demand-led and expensive acute stroke services, leaving little resource for community services. Though the benefits of VR to patient health are acknowledged, any cost savings would not be realized within the health budget. Social care commissioners, in times of budget restriction, focus on the most vulnerable, aiming to maintain independence and reduce care home admission. In the absence of evidence, there is a perception that the need for VR after stroke is relatively minor. Conclusions Factors which might facilitate commissioning of a VR service include adapting the service to align with commissioners’ requirements, making VR a targeted outcome of community stroke services, utilizing emerging opportunities for joint health and social care commissioning such as Health and Wellbeing Boards, and closer working with researchers to improve the evidence-base.

What is 'Early intervention' for work related difficulties for people with multiple sclerosis?: a case study report

Background: Employment matters and at diagnosis most people with multiple sclerosis are in full time work or education. 75% of people with multiple sclerosis report the condition has impacted on this employment or career opportunities. Early intervention to support people in work is advocated for in the literature. This paper starts the journey of exploring what is meant by early. Methods: A randomized control trial was undertaken offering either occupational therapy led early intervention or usual care to people diagnosed with multiple sclerosis within one year. Two cases were purposively selected from the treatment group and used to illustrate the importance as well as the nature of early intervention. Results: Both participants received occupational therapy led support which included fatigue management, advice about legal rights, support accessing services such as Access to Work, and support with disclosure in the workplace. Conclusions: Neither of the participants had reported any work problems at the point of referral. However the clinical intervention led to the identification of small concerns and worries. The education and support offered to these two participants alleviated these worries. Early support and education to enable people with multiple sclerosis to manage their condition in the work place can have a positive impact. This may equip them better for the journey ahead.
