Background and Purpose. Balance disability is common after stroke, but there is little detailed information about it. The aims of this study were to investigate the frequency of balance disability; to characterize different levels of disability; and to identify demographics, stroke pathology factors, and impairments associated with balance disability. Subjects. The subjects studied were 75 people with a first-time anterior circulation stroke; 37 subjects were men, the mean age was 71.5 years (SD=12.2), and 46 subjects (61%) had left hemiplegia. Methods. Prospective hospital-based cross-sectional surveys were carried out in 2 British National Health Service trusts. The subjects’ stroke pathology, demographics, balance disability, function, and neurologic impairments were recorded in a single testing session 2 to 4 weeks after stroke. Results. A total of 83% of the subjects (n=62) had a balance disability; of these, 17 (27%) could sit but not stand, 25 (40%) could stand but not step, and 20 (33%) could step and walk but still had limited balance. Subjects with the most severe balance disability had more severe strokes, impairments, and disabilities. Weakness and sensation were associated with balance disability. Subject demographics, stroke pathology, and visuospatial neglect were not associated with balance disability. Discussion and Conclusion. Subjects with the most severe balance disability had the most severe strokes, impairments, and disabilities. Subject demographics, stroke pathology, and visuospatial neglect were not associated with balance disability. [Tyson SF, Hanley M, Chillala J, et al. Balance disability after stroke.

Objective: To identify psychometrically robust and clinically feasible measures of walking and mobility in people with neurological conditions Data sources: MEDLINE, CINAHL, EMBASE, PEDro and AMED. Review methods: Independent reviewers selected and extracted data from articles that assessed the reliability, validity, sensitivity to change or clinical utility of measures of walking and mobility in adult neurological conditions. Measures with ‘good’ psychometrics and 9/10 clinical utility scores were recommended. Results: Seventeen measures were selected. Of these, the 5-m and 10-m walk tests, six-minute walk test, High Level Mobility Assessment Tool (HiMAT) and the Rivermead Mobility Index (RMI) reached the required standards and are usable in clinical practice. None of the recommended measures assessed wheelchair mobility. The least frequently assessed property was sensitivity to change. Further measures could be recommended if the minimal detectable change were demonstrated. Conclusion: The 5-m, 10-m and six-minute walk test, High Level Mobility Assessment Tool and the Rivermead Mobility Index are psychometrically robust measures of walking and mobility and are feasible for use in clinical practice.

Objective: To characterize the nature of sensory impairments after stroke, identify associated factors, and assess the relationships between sensory impairment, disability, and recovery. Methods: Prospective cross-sectional survey of 102 people with hemiparesis following their first stroke. Tactile and proprioceptive sensation in the affected arm and leg were measured using the Rivermead Assessment of Somatosensory Perception 2-4 weeks post-stroke. Demographics, stroke pathology, weakness, neglect, disability, and recovery were documented. Results: Tactile impairment was more common than proprioceptive (P < .000), impairment of discrimination was more common than detection (P < .000), and tactile sensation was more severely impaired in the leg than the arm ( P < .000). No difference in proprioception between the arm and leg (P = .703) or between proximal and distal joints (P = .589, P = .705) was found. The degree of weakness and the degree of stroke severity were significantly associated with sensory impairment; demographics, stroke side and type, and neglect were not associated. All the sensory modalities were significantly related to independence, mobility, and recovery (r = 0.287 [P < .011] to r = 0.533 [P < .000]). Conclusion: Sensory impairments of all modalities are common after stroke, although tactile impairment is more frequent than proprioceptive loss, especially in the leg. They are associated with the degree of weakness and the degree of stroke severity but not demographics, stroke pathology, or neglect, and they are related to mobility, independence in activities of daily living, and recovery.

Objective: To identify the barriers and facilitators to goal-setting during rehabilitation for stroke and other acquired brain injuries. Data sources: AMED, Proquest, CINAHL and MEDLINE. Review methods: Two reviewers independently screened, extracted data and assessed study quality using the Mixed Methods Appraisal Tool and undertook thematic content analysis for papers examining the barriers and facilitators to goal-setting during stroke/neurological rehabilitation (any design). Last searches were completed in May 2016. Results: Nine qualitative papers were selected, involving 202 participants in total: 88 patients, 89 health care professionals and 25 relatives of participating patients. Main barriers were: Differences in staff and patients perspectives of goal-setting; patient-related barriers; staff-related barriers, and organisational level barriers. Main facilitators were: individually tailored goal-setting processes, strategies to promote communication and understanding, and strategies to avoid disappointment and unrealistic goals. In addition, patients’ and staff’s knowledge, experience, skill, and engagement with goal-setting could be either a barrier (if these aspects were absent) or a facilitator (if they were present). Conclusion: The main barriers and facilitators to goal-setting during stroke rehabilitation have been identified. They suggest that current methods of goal-setting during inpatient/early stage stroke or neurological rehabilitation are not fit for purpose.

It is suggested the anterior cruciate ligament (ACL) plays a significant role in knee proprioception, however, the effect of ACL injury on knee proprioception is unclear. Studies utilising the two most common measurement techniques, joint position sense and threshold to detect passive motion, have provided evidence both for and against a proprioceptive deficient following ACL injury. The objective of the study was to undertake a meta-analysis investigating the effects of ACL injury, treated conservatively or by reconstruction, on proprioception of the knee, measured using joint position sense and/or threshold to detect passive movement techniques. Seven databases were searched from their inception to September 2013 using the subject headings 'anterior cruciate ligament, proprioception, postural sway, joint position sense, balance, equilibrium or posture' to identify relevant studies. PRISMA guidelines were followed as much as possible. Studies that investigated the effect of ACL injury on either knee joint kinaesthesia or position sense were included in this review. Two reviewers independently extracted data using a standardised assessment form. Comparisons were made using a fixed effect model with an inverse variance method using Review Manager Software (V5.1). Patients with ACL injury have poorer proprioception than people without such injuries (SMD=0.35°; P=0.001 and SMD=0.38°; P=0.03) when measured using joint position sense and threshold to detect passive motion techniques respectively. Patients had poorer proprioception in the injured than uninjured leg (SMD=0.52°; P<0.001) and the proprioception of people whose ACL was repaired was better than those whose ligament was left unrepaired (SMD=-0.62°; P<0.001). Heterogeneity of measurement techniques and lack of psychometric details. ACL injuries may cause knee proprioception deficits compared to uninjured knees and control groups. Although differences were statistically significant, the clinical significance of findings can be questioned. Clinical practitioners using joint position sense or threshold to detect passive motion techniques need to consider the reliability and validity of data provided.
