DOES REPETITIVE TASK TRAINING IMPROVE FUNCTIONAL ACTIVITY AFTER STROKE? A COCHRANE SYSTEMATIC REVIEW AND META-ANALYSIS

OBJECTIVE To determine if repetitive task training after stroke improves functional activity. DESIGN Systematic review and meta-analysis of trials comparing repetitive task training with attention control or usual care. DATA SOURCES The Cochrane Stroke Trials Register, electronic databases of published, unpublished and non-English language papers; conference proceedings, reference lists, and trial authors. REVIEW METHODS Included studies were randomized/quasi-randomized trials in adults after stroke where an active motor sequence aiming to improve functional activity was performed repetitively within a single training session. We used Cochrane Collaboration methods, resources, and software. RESULTS We included 14 trials with 17 intervention-control pairs and 659 participants. Results were statistically significant for walking distance (mean difference 54.6, 95% confidence interval (95% CI) 17.5, 91.7); walking speed (standardized mean difference (SMD) 0.29, 95% CI 0.04, 0.53); sit-to-stand (standard effect estimate 0.35, 95% CI 0.13, 0.56), and activities of daily living: SMD 0.29, 95% CI 0.07, 0.51; and of borderline statistical significance for measures of walking ability (SMD 0.25, 95% CI 0.00, 0.51), and global motor function (SMD 0.32, 95% CI -0.01, 0.66). There were no statistically significant differences for hand/arm functional activity, lower limb functional activity scales, or sitting/standing balance/reach. CONCLUSION Repetitive task training resulted in modest improvement across a range of lower limb outcome measures, but not upper limb outcome measures. Training may be sufficient to have a small impact on activities of daily living. Interventions involving elements of repetition and task training are diverse and difficult to classify: the results presented are specific to trials where both elements are clearly present in the intervention, without major confounding by other potential mechanisms of action.

Callers' experiences of making emergency calls at the onset of acute stroke: a qualitative study

Background Rapid access to emergency medical services (EMS) is essential at the onset of acute stroke, but significant delays in contacting EMS often occur. Objective To explore factors that influence the callers decision to contact EMS at the onset of stroke, and the callers experiences of the call. Methods Participants were identified through a purposive sample of admissions to two hospitals via ambulance with suspected stroke. Participants were interviewed using open-ended questions and content analysis was undertaken. Results 50 participants were recruited (median age 62 years, 68% female). Only one of the callers (2%) was the patient. Two themes were identified that influenced the initial decision to contact EMS at the onset of stroke: perceived seriousness, and receipt of lay or professional advice. Two themes were identified in relation to the communication between the caller and the call handler: symptom description by the caller, and emotional response to onset of stroke symptoms. Conclusions Many callers seek lay or professional advice prior to contacting EMS and some believe that the onset of acute stroke symptoms does not warrant an immediate 999 call. More public education is needed to improve awareness of stroke and the need for an urgent response.

“Can you send an ambulance please?”: a comparison of callers’ requests for emergency medical dispatch in non-stroke and stroke calls

Background Identifying ‘true stroke’ from an emergency medical services (EMS) call is challenging, with over 50% of strokes being misclassified. In a previous study, we examined the relationship between callers’ descriptions of stroke symptoms to the emergency medical dispatcher and the subsequent classification and prioritisation of EMS response. The aim of this subsequent study was to explore further the use of keywords by callers when making emergency calls, comparing stroke and non-stroke calls. Methods All non-stroke calls to one EMS dispatch centre between 8 March 2010 and 14 March 2010 were analysed. These were compared with the stroke calls made to one EMS dispatch centre between 1 October 2006 and 30 September 2007. Content analysis was used to explore the problems described by the caller, and findings were compared between non-stroke and stroke calls. Results 277 non-stroke calls were identified. Only eight (3%) callers mentioned stroke, 12 (4%) and 11 (4%) mentioned limb weakness and speech problems, respectively, while no caller mentioned more than one classic stroke symptom. This contrasted with 473 stroke calls, where 188 (40%) callers mentioned stroke, 70 (15%) limb weakness and 72 (15%) speech problems, and 14 (3%) mentioned more than one classic stroke symptom. Conclusions People who contact the EMS about non-stroke conditions rarely say stroke, limb weakness, speech problems or facial weakness. These words are more frequently used when people contact the EMS about stroke, although many calls relating to stroke patients do not mention any of these keywords.

‘It was like he was in the room with us’: patients’ and carers’ perspectives of telemedicine in acute stroke

Telemedicine can facilitate delivery of thrombolysis in acute stroke. The aim of this qualitative study was to explore patients’ and carers’ views of their experiences of using a stroke telemedicine system in order to contribute to the development of reliable and acceptable telemedicine systems and training for health‐care staff.

Postal and Face-to-Face Administration of Stroke Outcome Measures Can Mixed Modes Be Used?

Background and Purpose— Different modes of administration are used to collect stroke outcomes, even within the same study, potentially leading to different results. We investigated the effect of administration mode (postal questionnaire; face-to-face interview) on self-reports of activities of daily living and mood. Methods— The study was nested within a poststroke motivational interviewing trial. Activities of daily living (Barthel; Nottingham Extended) and mood (General Health Questionnaire; Yale) were collected at 3 and 12 months via postal questionnaire. Participants were approached to respond again via face-to-face interview. Paired t tests (McNemar test) and intraclass correlation coefficients (Cohen &kgr;) were used, with 95% CI, to compare scores (items). Results— Forty-four participants consented. Only Barthel scores were significantly different; they were 1.0 (95% CI, 0.5–1.6) higher face-to-face. The intraclass correlation coefficient for the Barthel was 0.90; for the other scales it was between 0.83 and 0.87. The Yale &kgr; was 0.72. Conclusions— Modes of administration might be used interchangeably, albeit in conjunction with corrections for the Barthel.
