The Impact of Physical Exercises with Elements of Dance Movement Therapy on Anthropometric Parameters and Physical Fitness among Functionally Limited Older Nursing Home Residents.

Changes in the composition of the body mass of functionally limited older patients may contribute to a decrease in functional fitness and the development of chronic diseases. This research aimed to assess the differences in anthropometric parameters and physical fitness of older patients, over the age of 65, in a 12-week clinical intervention study. Method: The study participants were nursing home inhabitants aged 65-85 who were functionally limited. Persons meeting the inclusion criteria were assigned to one of the three groups: Group 1-basic exercises/BE group (n = 56); Group 2-physical exercises with elements of dancing/PED group (n = 57); Group 3-control group/CO group (n = 56) routine care. The data were collected at the beginning of the study and at the 12-week mark. The outcome was observed for hand grip strength (HGS), arm curl test (ACT), Barthel Index (BI), Berg Balance Scale (BBS), triceps skin fold (TSF), waist-to-hip-ratio (WHR), and arm muscle area (AMA). Results: The study included 98 women and 71 men. The average age of the participants was 74.40 years. The analysis of the effects of the 12-week exercise program showed the greatest changes in HGS, ACT, and BI in the exercise groups, especially in the PED group compared to the BE group. Statistically significant differences in the examined parameters of the PED vs. BE vs. CO groups were demonstrated in favour of the exercising groups. In conclusion, a 12-week program of group physical exercises, both PED and BE, improves physical fitness indicators and anthropometric indicators.

The impact of physical exercises with elements of dance movement therapy on the upper limb grip strength and functional performance of elderly wheelchair users living in nursing homes - a randomized control trial.

INTRODUCTION: Over the last few decades, the quality of care and the quality of life of nursing home (NH) residents have significantly improved, but insufficient physical activity and social involvement still represent substantial challenges in modern nursing facilities. The main aim of this research was to assess the influence of physical exercises with dance movement therapy (DMT) elements on strength and other fitness components of the upper limbs and the overall functional performance of NH residents in wheelchairs compared to standard exercise programmes and usual care. METHOD: The study participants were persons aged 68-85 who lived in NH and used manual wheelchairs as a primary means of mobility. Individuals meeting the inclusion criteria were assigned to one of the three groups: Group 1, basic exercise/BE group (n = 55); group 2, physical exercises with elements of dance movement therapy/PED group (n = 55); and group 3, control group, usual care/CO group (n = 55). The intervention for both exercising groups consisted of a 30-min session, two times a week, for 12 weeks in total. Outcome assessments were performed at baseline, 12 weeks after baseline (immediately after the intervention) and 24 weeks after baseline (12 weeks after the intervention). The main outcome was observed for hand grip strength (HGS), while secondary outcomes for box and block test (BBT), arm curl test (ACT), back scratch test (BS), chair sit-and-reach (CSR), peak expiratory flow (PEF), Barthel Index (BI), Berg Balance Scale (BBS) and the range of motion of the shoulder. RESULTS: Prior to the start of the exercise programmes, all the tested groups were homogeneous. After 12 weeks the PED group presented higher statistically significant scores in HGSL, BBT, ACT, BS, CSR, BI, BBS: p < 0.001 and HGSR: p = 0.01, compared to the BE group. After 24 weeks from the beginning of the intervention the comparison between the PED group and the BE group showed statistically significant differences (p < 0.001) in favour of PED group in almost all areas: HGSR, HGSL, BBT: ACT, PEF, BS, CSR, BI. After 12 and 24 weeks both intervention groups performed better than the CO in all measures except for Katz ADL and shoulder extension. CONCLUSION: Twelve weeks of physical exercises had beneficial effects on the strength and fitness of the upper limbs and overall functional performance in both exercise groups. This study demonstrated that group performing physical exercises with elements of DMT obtained statistically better scores in the majority of analysed domains than other groups.

Psychometric Properties and Validation of the Polish Version of the 12-Item World Health Organization Disability Assessment Schedule 2.0 in Patients with Huntington's Disease.

BACKGROUND: Huntington's disease is a progressive neurodegenerative disorder that usually manifests in adulthood and is inherited in an autosomal dominant manner. The main aim of the study was to assess the psychometric properties of the 12-item WHO Disability Assessment Schedule (WHODAS) 2.0 in studying the level of disability in people with Huntington's disease. METHOD: This is a cross-sectional study that covered 128 people with Huntington's disease living in Poland. We examined scale score reliability, internal consistency, convergent validity, and known-group validity. The disability and quality of life of people with Huntington's disease were also assessed. RESULTS: The scale score reliability of the entire tool for the research group was high. The Cronbach's α test result for the whole scale was 0.97. Cronbach's α for individual domains ranged from 0.95 to 0.79. Time consistency for the overall result was 0.99 and for particular domains ranged from 0.91 to 0.99, which confirmed that the scale was consistent over time. All of the 12-item WHODAS 2.0 domains negatively correlated with all of the Huntington Quality of Life Instrument (H-QoL-I) domains. All correlation coefficients were statistically significant at the level of p < 0.001. The results obtained in the linear regression model showed that with each subsequent point of decrease in BMI the level of disability increases by an average of 0.83 points on the 12-item WHODAS 2.0 scale. With each subsequent year of the disease, the level of disability increases by an average of 1.39 points. CONCLUSIONS: This is the first study assessing disability by means of the WHODAS 2.0 in the HD patient population in Poland, and it is also one of the few studies evaluating the validity of the WHODAS 2.0 scale in assessing the disability of people with HD in accordance with the recommendations of DSM-5 (R). We have confirmed that the 12-item WHODAS 2.0 is an effective tool for assessing disability and changes in functioning among people with Huntington's disease.

Effect of Post-Stroke Rehabilitation on Body Mass Composition in Relation to Socio-Demographic and Clinical Factors.

Background and objectives: Stroke is one of the leading causes of morbidity, mortality and long-term adult disability. The aim of this study was to assess the changes in body mass composition in patients after stroke in connection with selected socio-demographic and clinical factors (sex, age, type of stroke and time from the first symptoms) following the rehabilitation process. Materials and Methods: The study group consisted of 100 post-stroke subjects who participated in a comprehensive rehabilitation program for a duration of five weeks. The measurements of body composition by a Tanita MC 780 MA analyser were performed on the day of admission to hospital, on the day of discharge (after 5 weeks) and 12 weeks after discharge from hospital. Results: It was shown that before rehabilitation (Exam I) in the study group there were significant differences in body composition relative to sex, age and time from stroke. The rates of fat mass % and visceral fat level decreased after rehabilitation (Exam II) in both males and females. Exam II, at the end hospital rehabilitation, showed lower levels of fat mass %, visceral fat level, as well as fat-free mass % and higher values of total body water % and muscle mass %. In Exam III, i.e., 12 weeks after discharge, all of the parameters retained their values. Conclusions: The study shows an association between stroke risk factors (primarily age, sex and time from the onset of the first symptoms of stroke) and body mass composition resulting from rehabilitation. The type of stroke and the effects of rehabilitation on body mass components showed no differences. Comprehensive rehabilitation had a positive effect on the body mass components.

Psychophysical Health Factors and Its Correlations in Elderly Wheelchair Users Who Live in Nursing Homes.

Background: The aging is a multi-faceted process comprising both-the physical and mental alterations. Thus, the aim of the study was to evaluate the variables affecting the psychophysical state of the elderly people using wheelchairs and living in nursing homes (NH). Methods: 165 older wheelchair users were included in the study after meeting the inclusion criteria and expressing written consent. The assessment involved cognitive functioning, depression, body balance and flexibility, lung capacity and upper limbs dexterity, strenght and endurance. The results showed negative correlation between depression and balance, upper limb dexterity and endurance and shoulder flexion. A positive correlation between cognitive functioning and balance, upper limb dexterity, strenght and endurance, lung capacity and joint mobility was determined. Also, the study proved positive correlation between daily functioning and functional fitness, muscle strength and endurance, body flexibility, joint mobility. The regression analysis showed that better scores in balance test and joint mobility implied with higher scores in cognitive functioning. The most important determinants of functional fitness were balance, hand grip strenght and joint mobility. Conclusion: The future study should be focused on developing interventions aimed at senior wheelchair users living in NHs to prevent the deterioration of their mental and physical fitness.

Return to work after stroke and related factors in Poland and abroad: A literature review.

BACKGROUND: The incidence of stroke is growing in various parts of the world and the condition most commonly affects the adult population. OBJECTIVES: The purpose of the study is to provide a narrative review of papers published in the last 11 years in English and in Polish and focusing on demographic characteristics of individuals returning to work after stroke, return to work rates, length of time post stroke to return to work as well as health conditions, or personal and environmental factors associated with return to work after stroke. The study also presents the situation regarding return to work after stroke in Poland in comparison to other countries. METHODS: The narrative review covers Polish and foreign literature published between 2007 and 2018. The number of records initially identified through English databases search amounted to 4,912. Five records were additionally identified through other sources (Polish databases). Ultimately 26 (21 foreign, 5 Polish) refereed publications were selected to be reviewed in this study, based on their relevance in terms of specific inclusion/exclusion criteria. RESULTS: The appraisal of Polish and English-language literature shows that stroke survivors' ability to return to work varies; in our country the rate being 43% and outside of Poland reaching the rate of 74.7%. Average time frames for return to work for stroke survivors include from 3 to 6 months, from 12 to 18 months and up to 3 years post stroke. One of the most frequently reported positive factors in the English-language literature is individually tailored vocational rehabilitation. There is a scarcity of studies related to return to work after stroke in Poland. CONCLUSIONS: The findings from studies included in this narrative review may suggest a need to improve the situation in Poland with regard to measures related to return to work after stroke, including vocational rehabilitation which is insufficiently available in Poland.

Analysis of the association between selected factors and outcomes of treadmill gait training with biofeedback in patients with chronic stroke.

OBJECTIVE: To examine the effects of age, time from stroke onset, gender and side of paresis in gait re-education with the use of treadmill with biofeedback, in patients with chronic stroke. METHODS: The study was performed with a group of 50 patients. 10-metre walk test, 2-minute walk test, "Up and Go" test, the number of steps performed with the paretic lower limb at a distance of 10 metres, Barthel index and FIM scale were used to assess the effects of rehabilitation. RESULTS: The study shows that the subjects' abilities and fitness prior to the rehabilitation were not related to age, sex or side of paresis. Analysis of the impact of age, time from stroke and sex on rehabilitation outcomes showed no statistically significant correlations. On the other hand, analysis of rehabilitation results relative to the side of paresis showed that the latter factor significantly differentiates rehabilitation outcomes measured with gait velocity test - p= 0.045. CONCLUSION: Age, duration of time from stroke onset, and sex do not affect outcomes of gait re-education based on treadmill training in patients at a chronic stage post-stroke and Brunnstrom recovery stage 3-4. Side of paresis significantly differentiates rehabilitation outcomes measured with speed test. The best scores in all the performance measures before rehabilitation were identified in the group 3-6 years after stroke.

Association Between Body Mass Index and Results of Rehabilitation in Patients After Stroke: A 3-Month Observational Follow-Up Study.

BACKGROUND We assessed the relationship between body mass index and results of rehabilitation in stroke patients. MATERIAL AND METHODS The study was carried out at the Clinical Rehabilitation Ward with Early Neurological Rehabilitation Unit at the Clinical Hospital. The examinations were performed 3 times. Based on inclusion and exclusion criteria, 128 subjects were qualified for the first examination, the second examination involved 114 subjects, and 100 stroke patients participated in the third examination. Body mass was examined with an accuracy of 0.1 kg, using a Tanita MC-780 MA body composition analyser. Body mass index (BMI) was calculated for all of the subjects. Effects of rehabilitation were assessed with the Barthel index and Ashworth scale. RESULTS Higher functional status in daily life, measured with the Barthel scale, was found in patients with normal body mass, compared to the overweight and obese subjects (examination I, II, and II). Exam I showed that before rehabilitation the overweight patients obtained significantly higher results in assessment of upper limbs, based on the Ashworth scale (mean=0.35±0.54) compared to the obese patients (mean=0.03±0.32) and those with normal body weight (mean=0.24±0.75). CONCLUSIONS Following hospital-based rehabilitation, patients with normal body mass achieved greater functional efficiency. The findings also show a trend towards normalization of BMI. The positive effect of rehabilitation was sustained for 3 months (Exam III), which may contribute to decreased risk of cardiovascular diseases and complications such as stroke.

Diet after Stroke and Its Impact on the Components of Body Mass and Functional Fitness-A 4-Month Observation.

The aim of the study was to assess the effect of various diets on BMI and selected components of body mass, i.e., fat mass (FAT%), visceral fat (VFAT level), muscle mass (PMM %), body water (TBW %), and functional fitness during a 4-month observation period. Examinations were conducted three times in a group of 100 people after a stroke. The study group was divided into four subgroups according to the type of diet applied. The components of body mass were assessed using the electrical bioimpedance method, and functional fitness using the Barthel scale, the Brunnström scale, and the modified Ashworth scale. Despite the fact that there were no significant differences among the diets applied, it was observed that each of them had a positive effect on the reduction of the mean BMI, FAT%, VFAT level, and the increase in TBW% and PMM%. At the same time, there was a significant improvement in the functional fitness of the hand and upper limb. Weight control and a change in eating habits after a stroke incident is extremely important as it promotes faster recovery and improved functional fitness.

Factors determining the effectiveness of conservative treatment in patients with carpal tunnel syndrome.

OBJECTIVES: The study aims to assess selected factors contributing to the long-term effects of the conservative treatment of carpal tunnel syndrome (CTS). MATERIAL AND METHODS: Forty-nine individuals diagnosed with CTS were enrolled in the study. The symptoms resulted from occupational hand overuse in 37 patients. The assessment involved 78 hands before the therapy (study 1) and 1 year after the end of the therapy (study 2). The clinical symptoms assessed included: pain, numbness, tingling, morning stiffness, vegetative disorders and difficulties in activities of daily living (ADL). The range of motion (ROM) in the hand joints and the pressure generated during the cylindrical grip were measured. Phalen's tests, an electrodiagnostic test and a 2-point discrimination study were performed. RESULTS: A significant reduction of symptoms and improvement in tested parameters were found in study 2. The largest ROM in the hand, the lowest level of pain and the largest reduction in the frequency of daytime tingling were found in the oldest patients in study 2. In subjects with better initial electrodiagnostic test results, a significant reduction in daytime numbness and daytime tingling was obtained. In individuals previously subjected to conservative therapy, a significant improvement in the ROM of the hand and a better quality of sensation were noted in study 2. A higher level of pain, a lower reduction in the frequency of daytime tingling, and a smaller improvement in ADL capacity were noted in individuals who overused their hands at work after the therapy. CONCLUSIONS: The effects of conservative CTS treatment after 1 year, expressed as the reduction of subjective symptoms, were independent of the patient's age. A worse initial electrodiagnostic test result is a predictor of less favorable therapy results. Hand overuse during occupational activity may negatively affect the effects of conservative treatment in individuals with CTS. A change in the nature of occupational activity positively influenced the long-term maintenance of the effects of conservative treatment. Int J Occup Med Environ Health. 2019;32(2):197-215.

The Wisconsin gait scale - The minimal clinically important difference.

BACKGROUND: Wisconsin Gait Scale (WGS) is an observational tool for the evaluation of gait quality in individuals after stroke with hemiplegia. It is divided into four subscales, which assess a total of fourteen spatiotemporal and kinematic parameters of gait observed during the consecutive gait phases. However, the WGS score change indicative of important and clinically meaningful change has not been determined. RESEARCH QUESTION: The study has been designed to define the minimal clinically important difference (MCID) of the WGS. METHODS: Four methods were used to determine the MCID for the WGS in 50 participants who had experienced a stroke: anchor-based study, distribution-based study, linear regression analysis and specification of the receiver operating characteristic (ROC) curve. RESULTS: In the anchor-based study, the mean change score in the MCID group was 1.9 points (the first MCID estimate). In the distribution-based study, the standard error of measurement for the no-change group was 0.3 (the second MCID estimate). The slope of the regression line was 1.21 which means than 1-point change in the Barthel Index (BI) is associated with 1.21-point change in the WGS. This translates to 2.25 points change in the WGS with 1.85 points change in the BI (the third MCID estimate). The best cut-off point, determined with ROC curve, was the value corresponding to 1 point of change in the WGS (the fourth MCID estimate). SIGNIFICANCE: We established that the MCID of the WGS was 2.25 points, based on the largest of the four MCID estimates. The value 2.25 of the MCID can help clinicians and researchers determine if the change in the scores on the WGS is clinically important. CLINICAL TRIAL REGISTRATION: Data are parts of the following clinical trial: ACTRN12617000436370.

Validity of the gait variability index for individuals after a stroke in a chronic stage of recovery.

BACKGROUND: Increased variability in spatiotemporal variables has been demonstrated in individuals after stroke. Gait Variability Index (GVI) has recently been proposed, potentially to be used as a standardized tool for quantifying gait impairment due to spatiotemporal variables. The experience with the GVI in patients after stroke is unknown. RESEARCH QUESTION: The aim of this study was to investigate the validity of the GVI as an outcome measure of gait disturbance after stroke. METHODS: 50 individuals (mean age 60.9 ± 11.2 years) after stroke at a chronic phase of recovery were included. The control group comprised 50 healthy subjects without gait disorders, matched for age and gender. Data on functional mobility and spatiotemporal gait parameters (BTS Smart system) was collected. RESULTS: The results showed lower mean GVI (mGVI) scores (mean 78.53 ± 6.12), lower GVI for the affected leg (mean 76.32 ± 7.98) and for the unaffected leg (mean 80.74 ± 4.68) in the individuals after stroke compared to the healthy subjects (mean 98.00 ± 6.32). This was significantly different from the control group mean for both mGVI, affected and unaffected leg - p < 0.001. The GVI for the affected leg and unaffected leg as well as the mGVI were significantly correlated with all clinical measures of functional mobility (0.7≤R|<0.9, 0.5≤|R|<0.7, p < 0.001). SIGNIFICANCE: The validity of the GVI appears to be confirmed for individuals after stroke at a chronic stage of recovery. The GVI is lower in individuals after stroke compared to healthy controls. The GVI showed moderate to strong correlations with validated clinical measures of functional mobility. Application of the GVI in the clinical practice will significantly facilitate assessment of gait in individuals after stroke, in comparison to the necessity to interpret a large number of data from 3-dimensional gait analysis. CLINICAL TRIAL REGISTRATION: Data are parts of the following clinical trial: ACTRN12617000436370 (anzctr.org.au).

The use of the Gait Variability Index for the evaluation of individuals after a stroke.

PURPOSE: The Gait Variability Index (GVI) summarizes overall gait quality, taking into account spatiotemporal parameters from a 3-dimensional gait analysis. However, there are no studies evaluating changes in gait patterns after stroke, based on the GVI. The study was designed to assess usefulness of the GVI for evaluation of gait pathology in subjects with stroke, compared to healthy individuals. METHODS: Spatiotemporal gait parameters were examined in a group of 50 subjects at a chronic stage post-stroke and in 50 healthy controls. The GVI was calculated based on the 9 spatiotemporal data. RESULTS: The findings show statistically significant differences between the values of the GVI for paretic and non-paretic limbs ( p < 0.001). Higher values of the index were identified in the case of non-paretic limb: 80.74 vs. 76.32. The GVI scores were decreased for both paretic and non-paretic limbs, compared to the controls - p < 0.001. CONCLUSIONS: The GDI score seems to be a viable tool for quantifying changes in gait pattern during evaluation of subjects with chronic post-stroke hemiparesis. Further studies should be conducted to validate the use of GVI in the post-stroke population.

The paediatric version of Wisconsin gait scale, adaptation for children with hemiplegic cerebral palsy: a prospective observational study.

BACKGROUND: In clinical practice there is a need for a specific scale enabling detailed and multifactorial assessment of gait in children with spastic hemiplegic cerebral palsy. The practical value of the present study is linked with the attempts to find a new, affordable, easy-to-use tool for gait assessment in children with spastic hemiplegic cerebral palsy. The objective of the study is to evaluate the Wisconsin Gait Scale (WGS) in terms of its inter- and intra-rater reliability in observational assessment of walking in children with hemiplegic cerebral palsy. METHODS: The study was conducted in a group of 34 patients with hemiplegic cerebral palsy. At the first stage, the original version of the ordinal WGS was used. The WGS, consisting of four subscales, evaluates fourteen gait parameters which can be observed during consecutive gait phases. At the second stage, a modification was introduced in the kinematics description of the knee and weight shift, in relation to the original scale. The same video recordings were rescored using the new, paediatric version of the WGS. Three independent examiners performed the assessment twice. Inter and intra-observer reliability of the modified WGS were determined. RESULTS: The findings show very high inter- and intra-observer reliability of the modified WGS. This was reflected by a lack of systematically oriented differences between the repeated measurements, very high value of Spearman's rank correlation coefficient 0.9 ≤ |R| < 1, very high value of ICC > 0.9, and low value of CV < 2.5% for the specific physical therapists. CONCLUSIONS: The new, ordinal, paediatric version of WGS, proposed by the authors, seems to be useful as an additional tool that can be used in qualitative observational gait assessment of children with spastic hemiplegic cerebral palsy. Practical dimension of the study lies in the fact that it proposes a simple, easy-to-use tool for a global gait assessment in children with spastic hemiplegic cerebral palsy. However, further research is needed to validate the modified WGS by comparing it to other observational scales and objective 3-dimensional spatiotemporal and kinematic gait parameters.

The Efficacy of Gait Training Using a Body Weight Support Treadmill and Visual Biofeedback in Patients with Subacute Stroke: A Randomized Controlled Trial.

BACKGROUND: This study was designed to determine whether or not gait training based on the use of treadmill with visual biofeedback and body weight support (BWS) would produce better effects in patients with subacute stroke compared to BWS treadmill training with no visual biofeedback. MATERIALS AND METHODS: 30 patients with subacute stroke were randomly assigned to do body weight supported treadmill training with visual biofeedback (BB group) or BWS treadmill training without visual biofeedback. Their gait was assessed with a 3D system (spatiotemporal gait parameters and symmetry index) and by means of 2-minute walk test (2 MWT), 10-metre walk test (10 MWT), and Timed Up & Go test. Subjects in both groups participated in 15 treadmill training sessions (30 minutes each). RESULTS: The participants from both groups achieved a statistically significant improvement in spatiotemporal gait parameters, walking speed, endurance, and mobility. The average change in the BB group after the end of the programme did not differ significantly compared to the change in the control group. The change in the symmetry index value of stance phase in the BB group was 0.03 (0.02) and in the control group was 0.02 (0.02). The difference was not statistically significant (p = 0.902). The statistically significantly higher improvement in the BB group was found in the range of walking speed (p = 0.003) and endurance (p = 0.012), but the difference between groups was of low clinical significance. CONCLUSIONS: The findings do not confirm that BWS treadmill training with the function of visual biofeedback leads to significantly greater improvement in gait compared to BWS treadmill training with no visual biofeedback at an early stage after stroke. This study was registered at ClinicalTrials.gov, ID: ACTRN12616001283460.

An assessment of the relationship between the items of the observational Wisconsin Gait Scale and the 3-dimensional spatiotemporal and kinematic parameters in post-stroke gait.

BACKGROUND: There are few reports in the literature investigating the relationship between observational gait scales used to assess individuals after a stroke and objective data acquired from 3-dimensional gait analysis (3DGA). RESEARCH QUESTION: The objective of this study was to compare the relationship between the specific items of the Wisconsin Gait Scale (WGS) and the matching 3-dimensional (3D) spatiotemporal and kinematic gait parameters in individuals after a stroke. In this way we evaluated whether using the simple, inexpensive, easy-to-use, observational WGS can fully substitute for the very costly and time-consuming 3DGA. METHODS: The study group comprised 50 participants who had experienced a stroke and were in the chronic stage of recovery. The study participants' gait was evaluated by means of the WGS; spatiotemporal and kinematic gait parameters were examined in the Gait Laboratory with the use of the BTS Smart system. The 3D recording of gait was performed using 2 video cameras positioned in such a way that it was possible to obtain images in the frontal and the sagittal plane. RESULTS: The findings show strong (0.7 ≤ |R| < 0.9; p < 0.001) or very strong (0.9≤ |R| < 1; p < 0.001) correlation between the specific items of the WGS and the matching 3D gait parameters. SIGNIFICANCE: The WGS is a diagnostic tool useful for conducting observational gait analysis in people with post-stroke hemiparesis and in situations when the costly objective methods of gait assessment cannot be applied for various reasons, the scale may be an effective tool enabling the assessment of gait. The WGS may be particularly useful in the subacute period of stroke as video recording of walking takes considerably less time than 3DGA. The study has been registered at the ClinicalTrials.gov, ID: ACTRN12617000436370.

Relationships between walking velocity and distance and the symmetry of temporospatial parameters in chronic post-stroke subjects.

PURPOSE: Subjects with post-stroke hemiparesis frequently present with asymmetric gait patterns. Symmetry, reflecting similarities in temporospatial, kinematic parameters, is an important measure of gait assessment. The study was designed to examine the relationships between asymmetry of temporal, spatial and kinematic gait parameters and walking velocity and distance. METHODS: Temporospatial and kinematic gait parameters were examined in a group of 50 chronic post-stroke subjects and in a group of 25 healthy controls. Symmetry ratio was calculated for all the parameters. Gait velocity was measured during 10-metre test, the walking distance during 2-Minute Walk Test, and balance during Up and Go Test. RESULTS: The relationship between stance phase duration symmetry and gait speed was at a moderate level (r = -0.43, p = 0.0173). There was a moderate relationship between swing phase symmetry and walking velocity and distance. The findings did not show a significant correlation between step length symmetry versus gait speed and distance. CONCLUSIONS: There is a mild relationship between self-selected gait velocity and walking distance versus temporal parameters symmetry. The findings do not confirm a relationship between self-selected gait velocity and walking distance versus spatial and kinematic parameters as well as balance. Likewise, no evidence confirms that asymmetry of temporal, spatial, kinematic gait parameters changes with the age of post-stroke subjects or is related to the length of time from stroke onset. Given the above, gait symmetry may be recognized as an important indicator of the level of gait control in post-stroke patients because it enables unique gait assessment, independent from other parameters.

Analysis of consistency between temporospatial gait parameters and gait assessment with the use of Wisconsin Gait Scale in post-stroke patients.

INTRODUCTION: Due to the increasing incidence and social effects of stroke there is a growing interest in finding methods enabling gait analysis in this group of patients. Observational techniques are predominantly applied in clinical practice; on the other hand advanced quantitative methods allow in-depth multidimensional gait assessment. The present study was designed to assess the consistency between temporospatial gait parameters acquired through 3-dimensional gait analysis and the results of gait assessment with the use of observational WGS in post stroke hemiparetic patients. MATERIAL AND METHOD: The study was performed in a group of 30 post-stroke patients, over 6 months from the onset of ischaemic stroke, who were able to walk unassisted. Gait assessment based on WGS was performed by an experienced physiotherapist, with the use of video recordings. Assessment of temporospatial parameters was based on gait analysis performed with BTS Smart system. RESULTS: The findings show moderate correlation between WGS based gait assessment and gait velocity (r=-0.39; p=0.0316). Similar relationship was identified between gait cycle duration and score in WGS for both unaffected (r=-0.36; p=0.0477) and affected side (r=-0.37; p=0.0426). Higher correlation level was demonstrated for stance phase on the unaffected side and gait assessment based on WGS (r=0.58; p=0.0009). CONCLUSIONS: Gait assessments with the use of temporospatial parameters and with observational WGS were found to produce moderate and good consistent results. WSG is a useful, simple tool for assessing gait in post stroke hemiparetic patients.

Changes in Gait Symmetry After Training on a Treadmill with Biofeedback in Chronic Stroke Patients: A 6-Month Follow-Up From a Randomized Controlled Trial.

BACKGROUND One of the most significant challenges for patients who survive a stroke is relearning basic motor tasks such as walking. The goal of this study was to evaluate whether training on a treadmill with visual biofeedback improves gait symmetry, as well as spatiotemporal and kinematic gait parameters, in stroke patients. MATERIAL AND METHODS Thirty patients in the chronic phase after a stroke were randomly allocated into groups with a rehabilitation program of treadmill training with or without visual biofeedback. The training program lasted 10 days. Spatiotemporal and kinematic gait parameters were evaluated. For all parameters analyzed, a symmetrical index was calculated. Follow-up studies were performed 6 months after completion of the program. RESULTS The symmetrical index had significantly normalized in terms of the step length (p=0.006), stance phase time, and inter-limb ratio in the intervention group. After 6 months, the improvement in the symmetry of the step length had been maintained. In the control group, no statistically significant change was observed in any of the parameters tested. There was no significant difference between the intervention group and the control group on completion of the program or at 6 months following the completion of the program. CONCLUSIONS Training on a treadmill has a significant effect on the improvement of spatiotemporal parameters and symmetry of gait in patients with chronic stroke. In the group with the treadmill training using visual biofeedback, no significantly greater improvement was observed.

The use of magnetic fields in treatment of patients with rheumatoid arthritis. Review of the literature.

Magnetic fields are commonly used in therapies designed for subjects with rheumatic diseases, yet the effects of magnetotherapy are not entirely clear in these disorders. This study is designed to examine the literature investigating applications of magnetotherapy in the treatment of rheumatoid arthritis (RA). The review focused on publications related to administering magnetotherapy in patients with RA. The databases Science Direct, SpringerLink, Medline, PubMed, and Polska Bibliografia Lekarska were searched for reports published since 2005. Despite the numerous reports showing an impact of magnetic field in subjects with RA, the effectiveness of magnetotherapy has not been explicitly confirmed. Given the above, further research appears to be necessary to clarify the impact of magnetic fields on biological systems, and the relationship between magnetic field intensity and the obtained results as well as their durability. The majority of clinical trials have failed to identify any undesirable outcomes or side effects of this physical therapeutic factor.
