Abstract Introduction: A proper assessment of gait pattern is a significant aspect in planning the process of teaching gait in hemiparetic post-stroke patients. The Wisconsin Gait Scale (WGS) is an observational tool for assessing post-stroke patients’ gait. The aim of the study was to assess test-retest reliability and internal consistency of the WGS and examine correlations between gait assessment made with the WGS and gait speed, Brunnström scale, Ashworth’s scale and the Barthel Index. Material and methods: The research included 36 post-stroke patients. The patients’ gait was assessed with the use of the Wisconsin Gait Scale, gait speed with the use of walk test, the level of motor control in a paretic lower limb – according to Brunnström recovery stages, muscle tone in a paretic lower limb – according to modified Ashworth’s scale and functional independence was assessed using the Barthel Index. Gait was assessed with the use of the WGS twice, with a 7-day interval, by three experienced physiotherapists. Results: The analysis of internal consistency of the WGS revealed that the Cronbach’s α coefficient was high in the case of all the three raters and ranged from 0.85 to 0.88. It was noted that the coefficient of variation for all the comparisons was below 10%. When assessing the repeatability of the results, it was revealed that correlations between both measurements made by particular raters were very strong and highly significant. The WGS results significantly correlated with Brunnström scale, Ashworth’s scale and gait speed. Conclusions: It was concluded that the WGS has a high internal consistency and test-retest reliability. Also, significant correlations were found between gait assessment made with the use of the WGS and gait speed, level of motor control and muscle tone of a paretic lower limb. The WGS constitutes a promising tool for a qualitative, observational analysis of gait in post-stroke patients and allows for proper planning, monitoring and assessing rehabilitation results.

Abstract Introduction: Gait recovery is one of the main objectives in the rehabilitation of post-stroke patients. The study aim was to assess the correlations between gait speed in post-stroke hemiparetic patients and the level of motor control in the paretic lower limb, the time from stroke onset, the subjects’ age as well as the impairment of proprioception and visual field. Materials and methods: This retrospective study was performed at the Clinical Rehabilitation Ward of the Regional Hospital No. 2 in Rzeszow. The study group consisted of 600 patients after a first stroke who walked independently. The measurements focused on gait speed assessed in a 10-meter walking test, motor control in the lower limb according to Brunnström recovery stages, proprioception in lower limbs, visual field as well as functional independence according to The Barthel Index. Results: The study revealed a slight negative correlation between gait speed and the subjects’ age (r = − 0.25). No correlation was found between mean gait speed and the time from stroke onset. On the other hand, gait speed strongly correlated both with the level of motor control in the lower limb (p = 0.0008) and the incidence of impaired proprioception. Additionally, a strong statistically significant correlation between the patients’ gait speed and the level of functional independence was found with the use of The Barthel Index. Conclusions: The level of motor control in the paretic lower limb and proprioception are vital factors affecting gait speed and functional independence. Patients with a higher level of functional independence demonstrated higher gait speed.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P < 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.

Test Retest Reliability

Background:Patients with TKA show impairments in standing balance up to 1 year after surgery. The impaired standing balance in TKA patients was found to be associated with falls risk and decreased functional level. Assessing of standing balance with objective and reliable assessments tools would therefore be extremely useful for determining accurate exercise program, and risks of falling, especially during the rehabilitative period when ambulation is at its most unsteady (1, 2). The stepping maneuver requires adequate strength and motor control to stabilize the body over the stance limb while the other leg is stepping, therefore the Step Test (ST) provides significant information for dynamic standing balance and lower limb motor control (3). The reliability of ST is reported in patient groups such as stroke, however, there is not any study that investigates the reliability of ST in patients with TKA in the current literature.Objectives:The purposes of this study were to determine the test-retest reliability and the minimal detectable change (MDC) of the ST in patients with TKA.Methods:40 patients with TKA due to knee osteoarthritis, operated by the same surgeon, were included in this study. Patients performed trials for ST twice on the same day. Between the first and second trials, patients waited for an hour on sitting position to prevent fatigue. The ST assesses an individual’s ability to place one foot onto a 7.5-cm-high step and then back down to the floor repeatedly as fast as possible for 15 seconds. The score is the number of steps completed in the 15-second period for each lower extremity. Scores for each lower extremity were recorded separately. Prior to the testing, the ST was demonstrated by the tester and all participants were allowed to a practice trial.Results:The ST showed an excellent test-retest reliability (ICC2,1=0.95) in this study. Standard error of measurement (SEM) and MDC95for ST were 0.37 and 1.02, respectively.Conclusion:This study found that the ST has an excellent test–retest reliability in patients with TKA. It is an effective and reliable tool for measuring dynamic standing balance and participant falls. As a performance-based clinical test, the ST is easy to score, can be applied in a short time as part of the routine medical examination. Therefore, inclusion of ST into a more comprehensive battery of performance-based measures of standing balance and lower limb motor control function in subjects with TKA should be considered.References:[1]Si, H.

Abstract Background Lower limb burns can significantly delay recovery of function. Measuring lower limb functional outcomes is challenging in the unique burn patient population and necessitates the use of reliable and valid tools. The aims of this study were to examine the test-retest reliability, sensitivity, and internal consistency of Sections 1 and 3 of the Lower Limb Functional Index-10 (LLFI-10) questionnaire for measuring functional ability in patients with lower limb burns over time. Methods Twenty-nine adult patients who had sustained a lower limb burn injury in the previous 12 months completed the test-retest procedure of the study. In addition, the minimal detectable change (MDC) was calculated for Section 1 and 3 of the LLFI-10. Section 1 is focused on the activity limitations experienced by patients with a lower limb disorder whereas Section 3 involves patients indicating their current percentage of pre-injury duties. Results Section 1 of the LLFI-10 demonstrated excellent test-retest reliability (intra-class correlation coefficient (ICC) 0.98, 95 % CI 0.96–0.99) whilst Section 3 demonstrated high test-retest reliability (ICC 0.88, 95 % CI 0.79–0.94). MDC scores for Sections 1 and 3 were 1.27 points and 30.22 %, respectively. Internal consistency was demonstrated with a significant negative association (rs = −0.83) between Sections 1 and 3 of the LLFI-10 (p < 0.001). Conclusions This study demonstrates that Section 1 and 3 of the LLFI-10 are reliable for measuring functional ability in patients who have sustained lower limb burns in the previous 12 months, and furthermore, Section 1 is sensitive to changes in patient function over time.

This study investigated the reliability and validity of the Korean version of the Utrecht Scale for Evaluation of Rehabilitation-Participation (K-USER-P) in patients with stroke. Stroke patients participated in this study. The Utrecht Scale for Evaluation of Rehabilitation-Participation was translated from English into Korean. A total of 120 questionnaires involving the K-USER-P were distributed to rehabilitation hospitals and centers by mail. Of those, 100 questionnaires were returned and 67 were included in the final analysis after exclusion of questionnaires with insufficient responses. We analyzed the questionnaires for internal consistency, test-retest reliability, and construct validity. The results indicated that internal consistency coefficients of the frequency, restriction, and satisfaction domains were 0.69, 0.66, and 0.67, respectively. Test-retest reliability was 0.63, 0.45, and 0.71 for the three domains, respectively. Intercorrelations between the SF-12 and the London Handicap Scale were generally moderate to good. The Korean version of the Utrecht Scale for Evaluation of Rehabilitation-Participation can be used as a measure of the participation level of stroke patients in clinical practice and the local community.

Post Stroke

Stroke is a leading cause of long-term disability. As a consequence of stroke and associated upper motor neuron (UMN) syndrome, stroke survivors are often left with muscle over activity, including spasticity. Spasticity is characterized by over- activity in muscles after injury to the central nervous system. When left untreated, post-stroke spasticity (PSS) can lead to contractures, pain and deformity, involuntary movement, and greater functional impairments (eg, reduced mobility, self-care and dressing). Spasticity is a common symptom after stroke, arising in about 30% of patients, and usually occurs within the first few days or weeks [1]. However, the onset of spasticity is highly variable and can occur in the short- medium or long-term post-stroke period [2]. Post-stroke hemiparesis, together with abnormal muscle tone, is a major cause of morbidity and disability. Patients with poststroke spasticity often demonstrate recognizable antigravity postural patterns (Fig 1) characterized by shoulder adduction, elbow and wrist flexion in the upper limb, hip adduction, knee extension and ankle plantar flexion in the lower limb. This “hemiplegic” posture, which is thought to result from increased motor neuron activity in antigravity muscles, significantly interferes with body image, balance and gait. BoNT-A, one of the most potent biologic toxins known to man acts by blocking neuromuscular transmission via inhibiting acetylcholine release [3]. BoNT-A treatment in post-stroke upper and lower limb spasticity is a safe and effective procedure to decrease muscle tone and increase the range of motion. More recent studies are demonstrating the importance for the rehabilitation therapist intervention to work alongside the physician to create more positive and significant effects on active function [4]. Daily stretching exercise is the key for the long-lasting benefits. BoNT-A Injections, Ultrasound guided technique, performed by a Physician in combination with physiotherapy and outcomes measurements are used to improve upper and lower limb function in stroke patients with spasticity in the clinical setting [5]. We would like to share our experience on the benefit of the ultrasound guided technique to target the muscles and our results in setting up a spasticity clinic for post-stroke patients.

Abstract Background Hemodialysis is considered a major therapeutic method for patients with chronic kidney disease. Pruritus is a common complaint of hemodialysis patients. The 5-D pruritus scale is amongst the most common tools to evaluate several dimensions of itch. Psychometric properties of the 5-D scale have not been evaluated in Persian speaking population with hemodialysis; hence, the objective of this study was to assess reliability and validity of the Persian version of the scale. Methods Ninety hemodialysis patients (men: 50, women: 40, mean age: 54.4 years) participated in this cross-sectional study. The final Persian version of 5-D scale was given to the participants. Tests Compared: One-third of the participants completed the scale twice within 3–7 days apart to evaluate test- retest reliability. Other psychometric properties including internal consistency, absolute reliability, convergent, discriminative and construct validity, floor/ceiling effects were also evaluated. Results The Persian 5-D scale has strong test-retest reliability (ICC= 0.98) and internal consistency (Cronbach’s alpha= 0.99). Standard error of measurement and minimal detectable change were 0.33 and 0.91, respectively. Regarding convergent validity, the scale had moderate correlation with numeric rating scale (r =0.67) and quality of life questionnaire related to itch (r = 0.59). Exploratory factor analysis revealed two factors within the scale. No floor or ceiling effect was found for the scale. Conclusion The Persian version of 5-D the itching scale is a brief instrument with acceptable reliability and validity. Therefore, the scale could be used by experts, nurses, and other health service providers to evaluate pruritus among Persian speaking hemodialysis patients.
