The Reliability and Validity of the OneStep Smartphone Application for Gait Analysis among Patients Undergoing Rehabilitation for Unilateral Lower Limb Disability.

An easy-to-use and reliable tool is essential for gait assessment of people with gait pathologies. This study aimed to assess the reliability and validity of the OneStep smartphone application compared to the C-Mill-VR+ treadmill (Motek, Nederlands), among patients undergoing rehabilitation for unilateral lower extremity disability. Spatiotemporal gait parameters were extracted from the treadmill and from two smartphones, one on each leg. Inter-device reliability was evaluated using Pearson correlation, intra-cluster correlation coefficient (ICC), and Cohen's d, comparing the application's readings from the two phones. Validity was assessed by comparing readings from each phone to the treadmill. Twenty-eight patients completed the study; the median age was 45.5 years, and 61% were males. The ICC between the phones showed a high correlation (r = 0.89-1) and good-to-excellent reliability (ICC range, 0.77-1) for all the gait parameters examined. The correlations between the phones and the treadmill were mostly above 0.8. The ICC between each phone and the treadmill demonstrated moderate-to-excellent validity for all the gait parameters (range, 0.58-1). Only 'step length of the impaired leg' showed poor-to-good validity (range, 0.37-0.84). Cohen's d effect size was small (d < 0.5) for all the parameters. The studied application demonstrated good reliability and validity for spatiotemporal gait assessment in patients with unilateral lower limb disability.

Does hemiplegic shoulder pain share clinical and sensory characteristics with central neuropathic pain? A comparative study.

BACKGROUND: Hemiplegic shoulder pain (HSP) is a common poststroke complication and is considered to be a chronic pain syndrome. It is negatively correlated with the functional recovery of the affected arm and the quality of life of the individual. It also leads to a longer length of stay in rehabilitation. Today, there is no consensus as to the underlying mechanism causing HSP, making the syndrome difficult to treat. AIM: The aim of this study was to compare the clinical and sensory profile of individuals with HSP to that of individuals with established central neuropathic pain (CNP) in order to identify common features and the presence of neuropathic components in HSP. DESIGN: Cross sectional controlled study. SETTINGS: Outpatient rehabilitation clinics. POPULATION: Sixteen chronic HSP patients and 18 chronic CNP patients with spinal cord injury (SCI-CNP). METHODS: The chronic pain characteristics, thresholds of thermal and tactile sensations and presence of pathological sensations were compared between groups, and between painful and pain free body regions within groups. Correlations were calculated between HSP intensity and sensory and musculoskeletal characteristics. RESULTS: Patients with HSP and patients with SCI-CNP had similar decrease of thermal sensibility in the painful compared to intact body regions and both groups presented similar rates of pathological sensations in painful regions. HSP and SCI-CNP differed however, in the quality of pain and aggravating factors. Significant correlations were found between HSP intensity and heat-pain threshold, presence of subluxation and spasticity. CONCLUSIONS: The similarities between HSP and SCI-CNP and the altered spinothalamic function and sensitization suggest that HSP has neuropathic components in its mechanism. Nevertheless, the unique features of HSP point towards additional possible mechanisms. CLINICAL REHABILITATION IMPACT: The use of specific therapy options for neuropathic pain should be considered when treating patients with HSP.

Israeli Dying Patient Act: physician knowledge and attitudes.

OBJECTIVES: The recently enacted Israeli Dying Patient Act was designed to strike balance between enhancing patient autonomy in end-of-life decision making and cultural/religious norms that are in opposition to active euthanasia and physician-assisted suicide (PAS). The current study evaluated physician attitudes regarding active and passive euthanasia, and their knowledge of specific aspects of the law. METHODS: A survey was administered to a convenience sample of hospital-based physicians treating terminal patients. Physicians were queried about their attitudes regarding euthanasia and PAS. Physicians were also queried about specific aspects of the law and whether they had sufficient resources to uphold the law. RESULTS: Surveys were distributed to 270 physicians and 100 were returned and evaluated (37%). Nearly all physicians supported passive euthanasia (withholding treatment), whereas over 40% maintained that active forms of euthanasia should be allowed for terminal patients in severe physical pain. Multivariate analysis showed a negative relationship between support for more active forms of euthanasia and physicians' self-reported religiosity. Physicians cited lack of time as a reason for not complying with the new law. Physicians had a familiarity with the general aspects of the new legislation, but a large proportion was not aware of the specifics of the law. CONCLUSIONS: Compared with previous surveys, a larger number of physicians support passive euthanasia. A sizable percentage of physicians would be willing to participate in active euthanasia and even PAS. Attitudes toward euthanasia are influenced by religious factors.
