Telerehabilitation systems have the potential to enable therapists to monitor and assist stroke patients in achieving high-intensity upper extremity exercise in the home environment. We adopted an iterative user-centred approach, including multiple data sources and meetings with end-users and stakeholders to define the user requirements for home-based upper extremity rehabilitation using wearable motion sensors for subacute stroke patients. We performed a requirement analysis consisting of the following steps: 1) context & groundwork; 2) eliciting requirements; 3) modelling & analysis; 4) agreeing requirements. During these steps, a pragmatic literature search, interviews and focus groups with stroke patients, physiotherapists and occupational therapists were performed. The results were systematically analysed and prioritised into "must-haves", "should-haves", and "could-haves". We formulated 33 functional requirements: eighteen must-have requirements related to blended care (2), exercise principles (7), exercise delivery (3), exercise evaluation (4), and usability (2); ten should-haves; and five could-haves. Six movement components, including twelve exercises and five combination exercises, are required. For each exercise, appropriate exercise measures were defined. This study provides an overview of functional requirements, required exercises, and required exercise measures for home-based upper extremity rehabilitation using wearable motion sensors for stroke patients, which can be used to develop home-based upper extremity rehabilitation interventions. Moreover, the comprehensive and systematic requirement analysis used in this study can be applied by other researchers and developers when extracting requirements for designing a system or intervention in a medical context. This study provides an extensive overview of user requirements for home-based upper extremity rehabilitation using wearable motion sensors in stroke patients. These requirements can be used as a basis for developing home-based UE telerehabilitation interventions. Including these requirements may facilitate the clinical implementation of such telerehabilitation systems. The comprehensive and systematic approach used in this sudy can be applied by other researchers and developers when extracting requirements for designing a system or intervention in a medical context.

Reflex sympathetic dystrophy syndrome (RSD) is a neurogenic pain syndrome characterized by pain, vasomotor and dystrophic changes, and often motor impairments. This study evaluated the effectiveness of brachial plexus blockade with local anaesthetic drugs as a treatment for this condition. Three patients responded well; three did not. (DB)

Objectives: To investigate the effect of carrying the apolipoprotein epsilon 4 (APOE-in4) allele on global functional outcome, on activity limitations and participation restrictions, and on community integration at 3, 6, 12, 18, 24 and 36 months after traumatic brain injury.Method: The Glasgow Outcome Scale (GOS), the Sickness Impact Profile-68 (SIP-68) and the Community Integration Questionnaire (CIQ) were assessed in 79 moderate and severe traumatic brain injury patients at 3, 6, 12, 18, 24 and 36 months post injury. Repeated measures analyses of variance were performed with APOE-in4 status and time of measurement as independent variables and the GOS, SIP-68 and CIQ as dependent variables. Analyses were adjusted for baseline age, gender and Glasgow Coma Scale.Results: Patients with the APOE-in4 allele had a significantly better global functional outcome on the GOS than patients without the APOE-in4 allele. No significant associations were found between APOE-in4 status and the SIP-68 and CIQ.Discussion: In contrast to other studies, we found that carrying the APOE-in4 allele had a protective influence on outcome. Multiple mechanisms, and in some cases competitive mechanisms, may explain the variable relation between the APOE-in4 allele and outcome after traumatic brain injury. [ABSTRACT FROM AUTHOR]

Background: 10-20% of children and youth with mild traumatic brain injury (mTBI) suffer from long-term cognitive impairments with, supposedly, a negative impact on most domains of functioning., Objectives: To describe cognitive functioning and participation in children and youth two-years post-mTBI and to determine associated risk factors., Methods: Cross-sectional study among 73 patients (aged 6-22 years), hospital diagnosed with mTBI. Linear regression modelling was used to investigate the effect of potential predictors on cognitive functioning as measured with a neuropsychological assessment (NPA), two-years post-injury. Extent of participation was assessed using the Child and Adolescent Scale of Participation and correlation analysis was conducted to examine its association with level of cognitive functioning., Results: 7-15% of all participants had impaired cognitive functions, especially in the domains of processing speed, inhibitory control, cognitive flexibility, visuospatial constructional ability and visuospatial memory. Lower level of education and pre-injury cognitive problems were predictive for a lower level of long-term cognitive functioning. Slower inhibition speed, impaired visuospatial and verbal working memory were associated with reduced participation., Discussion and Conclusions: Persisting cognitive problems two years after mTBI were mostly related to the lower level of education and to pre-injury cognitive problems. Although participation of the patients was reported by parents to be relatively high, slower inhibition speed, impaired visuospatial and verbal working memory were associated with reduced participation.

Purpose: To examine whether the caregivers' coping style is associated with the functional outcome of the traumatic brain injury (TBI) patient 1 year post-injury., Method: A cross-sectional study among patients with a TBI, including their primary caregivers. The study included 51 patients aged 17-64 years with a moderate-to-severe TBI and 51 caregivers (23 parents and 28 partners) aged 23-67 years. The coping preferences of the caregivers were assessed at minimum 6 and maximum 12 months post-injury, by filling out the Utrecht Coping List (UCL) and were related to limitations in activity, as measured with the Frenchay Activities Index and with restrictions in participation as measured with the Sickness Impact Profile-68 of TBI patients 1 year post-injury. The patients were interviewed at their homes; the caregivers received and returned the UCL by mail., Results: The patients' age and the caregivers' coping style are independently associated with restrictions in participation 1 year post-injury., Conclusions: A passive coping style of the primary caregiver is negatively associated with the patient's functional outcome in terms of participation in society.

So far, research on quality of life after stroke has focused mainly on elderly patients. This study is targeted at younger stroke patients and their partners, aiming to evaluate stroke impact, as related to coping strategy. For our pilot study, eight patients who had suffered a stroke and four partners completed the Impact of Event Scale questionnaire. The mean age was 47.6 years in patients and 44.5 years in partners. The patients' level of activities of daily life was assessed using the Barthel Index. They were then interviewed to obtain information with respect to stroke impact and coping. The Schedule for the Evaluation of Individual Quality of Life procedure was carried out to measure quality of life, and stroke impact was quantified using Visual Analogue Scales. On average, patients scored 19.25 on the Barthel Index. Quality of life had deteriorated by 20.1% in patients, whereas partners did not show a decline in quality of life. However, well-being was inversely correlated among patients and partners. Accommodative coping was positively correlated with quality of life in both patients and partners. Conversely, assimilation was negatively related to quality of life in patients.

This report describes the case of a multitrauma patient who underwent an amputation of the left arm and had a complicated left crural fracture with a delayed union. He was treated in an inpatient setting for preprosthetic training for a myoelectric prosthesis and to regain walking abilities. After consolidation of the crural fracture, complex regional pain syndrome type I (CRPS I) developed in the left foreleg, which hindered mobilization. Topical capsaicin .075% was prescribed and a stress-loading mobilization schema was instituted. No other treatment modalities directed at CRPS I were added. After 6 weeks, no signs or symptoms of CRPS I were present and capsaicin was discontinued. Capsaicin is a well-accepted and documented treatment modality in neuropathic pain states such as postherpetic neuralgia. However, it has rarely been described in CRPS I. Capsaicin is discussed within the framework of recent insights in the neurobiology of nociception, and it is concluded that it may provide a theory-driven treatment for CRPS I, especially in the acute stage, that facilitates physical therapy and prevents peripheral and spinal sensitization.

Studies on the aetiology and treatment of post-stroke hand oedema and shoulder-hand syndrome (SHS) published from January 1973 until August 1998 were identified. Eleven studies were included with at least some control for confounding. These were evaluated on 11 methodological criteria and by standardized effect sizes. There were five aetiological studies: four cohort studies and one study consisting of two case series using a within-subjects design. The matters investigated included lymph scintigraphy in hand oedema, bone scintigraphy, putative risk factors and the existence of autonomic dysregulation and peripheral nerve lesions in SHS. There were six therapeutic studies: one randomized controlled trial, one non-randomized controlled trial, one cohort study and three case series, of which two studies used a within-subjects design. These studies investigated continuous passive motion and neuromuscular stimulation in hand oedema as well as oral corticosteroids, intramuscular calcitonin and trauma prevention in SHS. A great diversity of pathophysiological and therapeutic insight was found. Based on systematic analysis of the literature, the following conclusions seem justified: (i) the shoulder is involved in only half of the cases with painful swelling of wrist and hand, suggesting a "wrist-hand syndrome" between simple hand oedema and SHS; (ii) hand oedema is not lymphoedema; (iii) SHS usually coincides with increased arterial blood flow; (iv) trauma causes aseptic joint inflammations in SHS; (v) no specific treatment has yet proven its advantage over other physical methods for reducing hand oedema; and (vi) oral corticosteroids are the most effective treatment for SHS.

Objective: Evaluation of immune system function in patients with reflex sympathetic dystrophy (RSD)., Design: Survey on blood samples obtained from RSD patients and from a randomly selected control group. The lymphocyte populations (T, B, NK cells), and the activated T cells (CD25, and HLA-Dr-positive CD4 and CD8 cells) were analyzed by flow cytometry with dual-color direct immunofluorescence after whole-blood lysis. Clinical chemistry parameters were analyzed in additional serum samples., Setting: Tertiary care center (outpatient rehabilitation clinic)., Subjects: Thirteen patients (nine women) with RSD and a control group of 21 healthy individuals., Main Outcome Measures: The results of the flow cytometry analysis of RSD patients were related to those of the control subjects. Means were analyzed, and confidence intervals for differences of the means were calculated. The means of the clinical chemical analysis were related to local reference values., Results: The flow cytometry analysis did not differ between RSD patients and healthy controls. Although in some patients an individual parameter of clinical chemical analysis differed from its reference value, all of the mean values were within reference limits. Stratification on medications with immunomodulatory effects and on probability of a definite diagnosis of RSD had no influence on the results., Conclusion: No association between immunologic indices and RSD was found. This finding is relevant, because recent theories stress that it is not the sympathetic nervous system but a local inflammatory reaction that is fundamental in the pathogenesis of RSD. The results of this study do not support this theory.

Objective: Quantitative evaluation of static and dynamic aspects of postural instability as a long-term consequence of traumatic brain injury (TBI)., Design: Experimental two-group design., Setting: Outpatient rehabilitation department., Patients and Other Participants: From a consecutive sample of TBI patients at least 6 months after trauma, 20 subjects were selected who complained of reduced gross motor skills but showed no sensorimotor impairments in a standard neurological examination (11 men, 9 women; mean age 36.2 +/- 10.7 years). Thirteen patients had sustained mild, 2 moderate, and 5 severe TBI. Twenty healthy controls were matched for age and gender., Intervention: None., Main Outcome Measures: A dual-plate force platform recorded the amplitude and velocity of the center-of-pressure fluctuations in the anteroposterior (AP) and lateral (LAT) sway directions during quiet standing. Also, the speed and fluency of weight shifting using visual feedback was registered. Both balance tasks were combined with an arithmetic task, whereas quiet standing was also tested with visual deprivation., Results: Compared to controls, TBI patients showed an increase of over 50% in AP and LAT sway, and a weight-shifting speed 20% lower. Dual-task interference was never significant. Visual deprivation was most detrimental for the TBI patients, particularly for LAT sway control., Conclusion: A long-term overall reduction in both static and dynamic control of posture can be present after TBI, even in patients without clear neurological deficits. Force-plate recordings can identify such (latent) balance problems. Visual deprivation during quiet standing appears a simple, sensitive test for postural instability related to sensory integration deficits.
