Pediatric Balance Scale: Translation and Cross-Cultural Adaptation Into Greek.

PURPOSE: Cross-cultural adaptation of the Pediatric Balance Scale (PBS) into Greek. METHODS: The PBS was forward-back translated and evaluated for content equivalence. The Greek PBS (PBSGR) was administered to children with movement impairments by 2 pediatric physical therapists. The scale was readministered to the same children after 3 weeks (test-retest reliability) and to children with typical development for discriminant validity. The 1-minute walk test was administered to test the scale's concurrent validity. RESULTS: Psychometric testing was completed on 26 children with movement impairments. The scale had excellent interrater and test-retest reliability and internal consistency. Moderate correlation was observed between PBSGR and 1-minute walk. Children with movement impairment had significantly lower PBSGR scores than children with typical development. CONCLUSIONS: Acceptable reliability, concurrent validity, and discriminant validity were observed for the PBSGR.

Attitudes towards people with disabilities across different healthcare undergraduate students: A cluster analysis approach.

BACKGROUND AND PURPOSE: Negative attitudes towards disability amongst healthcare professionals endanger social inclusion of people with disabilities (PwD). This study aimed to investigate the attitude of undergraduate healthcare students of various disciplines towards PwD, including specific aspects of their attitude. METHODS: We assessed the attitudes of university students, including physiotherapy, speech therapy, nursing, social work and medical students, through the Greek Interaction with Disabled Person Scale (IDPS) in a survey. Data were analysed using a two-step clustering technique. RESULTS: Four hundred-eighty undergraduate healthcare students (21.4 ± 5.3 years-old; 135 males, 345 females) were recruited. Two-step cluster analysis identified three homogenous subgroups labelled Least positive attitude (42.3%), Moderately positive attitude (26.9%), and Most positive attitude (30.8%) groups. Τhe main differences in healthcare students' attitudes between the three distinct groups appeared to be in feelings of sympathy, fear and susceptibility towards disability, suggesting that these aspects of attitude needed to be primarily addressed. Results also revealed that females, being in higher semester/year of studies, having completed a clinical module with PwD and having frequent contact with PwD were related to more positive attitudes. CONCLUSION: Taking into account that the majority of the healthcare students' sample yielded least and moderately positive attitudes, towards PwD, further actions should be taken for promoting more positive attitudes towards disability. A social model in teaching to increase student's awareness of PwD and skills to work with these people, having PwD themselves teaching such modules, focussing on positive experiences and reminding the students of the benefits of having positive attitudes towards PwD, as well as promoting ways to increase the contact of healthcare students with PwD (such as teaching in co-operation with organisations of PwD or finding alternative clinical placements with PwD), can be beneficial in promoting more positive attitudes towards disability.

What are the optimum training parameters of progressive resistance exercise for changes in muscle function, activity and participation in people with cerebral palsy? A systematic review and meta-regression.

OBJECTIVES: To explore the effect of progressive resistance exercise (PRE) on impairment, activity and participation of people with cerebral palsy (CP). Also, to determine which programme parameters provide the most beneficial effects. DATA SOURCES: Electronic databases searched from the earliest available time. ELIGIBILITY CRITERIA: Randomised controlled trials (RCTs) implementing PRE as an intervention in people with cerebral palsy were included. STUDIES APPRAISAL & SYNTHESIS METHODS: Methodological quality of trials was assessed with the PEDro scale. Meta-analysis and meta-regression were completed. RESULTS: We included 20 reports of 16 RCTs (n = 504 participants). Results demonstrated low certainty evidence that PRE improved muscle strength (pooled standardised mean difference (SMD)= 0.59 (95%CI: 0.16-1.01; I²=70%). This increase in muscle strength was maintained an average of 11 weeks after training stopped. Τhere was also moderate certainty evidence that it is inconclusive whether PRE has a small effect on gross motor function (SMD= 0.14 (95%CI: -0.09 to 0.36; I²=0%) or participation (SMD= 0.26 (95%CIs: -0.02 to 0.54; I²=0%). When PRE was compared with other therapy there were no between-group differences. Meta-regression demonstrated no effect of PRE intensity or training volume (frequency x total duration) on muscle strength (p > 0.5). No serious adverse events were reported. There is lack of evidence of the effectiveness of PRE in adults and non-ambulatory people with CP. CONCLUSIONS: PRE is safe and increases muscle strength in young people with CP, which is maintained after training stops. The increase in muscle strength is unrelated to the PRE intensity or dose.

The Interaction with Disabled Persons Scale: evidencing construct validity with factor analysis and measurement invariance in Greek-speaking healthcare students.

PURPOSE: To explore the construct validity and reliability of the Greek version of the Interaction with Disabled Persons Scale (IDPS) amongst healthcare students. METHODS: Greek IDPS factors were extracted and confirmed by Analysis of Moment Structures. Measurement invariance for the group of students completing a clinical module with people with disabilities was also evaluated. The scale was distributed twice, 3 weeks apart (test-retest reliability) to sample. Greek IDPS scores amongst students with frequent contact with people with disabilities were compared with those with infrequent contact (discriminant validity). RESULTS: 327 healthcare students (21.25 ± 4.3 years, 118 males) participated. Exploratory factor analysis extracted 6 factors explaining 55.66% of total variance. Confirmatory factor analysis showed a good fit of the model (AGFI = 0.95 > 0.90, RMSEA = 0.07 < 0.08, CFI = 0.95 ≥ 0.90, SRMR = 0.00 < 0.08). An adequate fit for the students completing a clinical practice module was observed. The scale's test-retest reliability and internal consistency were excellent; ICC(2,1)=0.86 (CIs:0.82-0.89) and Cronbach's α = 0.87, respectively. Statistically significant differences between the two student groups were yielded; students with frequent contact with people with disabilities had lower scores (mean difference: -4.5; CI: -6.6 to -2.4), suggesting that they were significantly more comfortable with people with disabilities than the students with infrequent contact. CONCLUSION: The Greek IDPS provided sufficient validity and reliability evidence for evaluating healthcare students' perceptions and attitudes towards people with disabilities.IMPLICATIONS FOR REHABILITATIONThe Greek IDPS demonstrated sufficient validity and reliability evidence to assess the Greek-speaking healthcare students' perceptions and attitudes towards people with disabilitiesCompleting a clinical module working with people with disabilities is not enough to produce adequately positive attitudes in Greek-speaking undergraduate healthcare students. Therefore, faculties need to organize further actions, such as lectures by people with disabilities, students' role play, and discussions or events in co-operation with people with disabilities.

The Interaction with Disabled Persons Scale: translation and cross-cultural validation into Greek.

AIM: Cross-cultural adaptation of the Interaction with Disabled Persons Scale (IDPS) into Greek. METHODS: The IDPS was forward and back-translated by two bilingual physiotherapists and a Greek-English translator, respectively. Greek-speaking health professionals provided modifications in order to develop the final version of the Scale. Health professionals filled in the Greek version of the IDPS and the Caring Behaviors Inventory (for criterion validity). The factors of the Greek IDPS were extracted as well. After 8-10 days, the scale was re-distributed to the same health professionals (test-retest reliability) and to a general population sample (discriminant validity). RESULTS: Eighty-seven health professionals (36 ± 7.6 years) and 80 general population participants (44 ± 11.6 years) participated. There was a trend for the Greek IDPS variability to predict the variability of the Caring Behaviors Inventory (r2 = 0.05; p = 0.054), but the coefficient of determination was low. An explanatory factor analysis extracted four factors explaining 66.66% of the total variance, confirmed by reliability analysis. The health care professionals had a significantly lower score than the general population in the Greek IDPS (mean difference: -11.0; confidence interval: -7.3 to -14.7), indicating familiarisation with the management of people with disability. The scale reliability and internal consistency were excellent; ICC(2,1) = 0.92 (confidence interval: 0.87-0.95) and Cronbach's α = 0.96 respectively. No ceiling or floor effects were observed. CONCLUSIONS: Substantial validity and reliability were observed for the Greek IDPS to assess Greek health professionals' attitudes towards people with disabilities.Implications for rehabilitationThe Greek IDPS version was shown to be comprehensible, and has demonstrated a sufficient amount of validity and reliability for assessing the perceptions and attitudes of Greek health professionals towards people with disabilities.Exploring attitudes towards people with disabilities in Greek-speaking populations, especially health professionals, with a scale such as the Greek IDPS is very important as it can help promote positive changes in approaches towards disability.

Mechanically assisted walking training for walking, participation, and quality of life in children with cerebral palsy.

BACKGROUND: Cerebral palsy is the most common physical disability in childhood. Mechanically assisted walking training can be provided with or without body weight support to enable children with cerebral palsy to perform repetitive practice of complex gait cycles. It is important to examine the effects of mechanically assisted walking training to identify evidence-based treatments to improve walking performance. OBJECTIVES: To assess the effects of mechanically assisted walking training compared to control for walking, participation, and quality of life in children with cerebral palsy 3 to 18 years of age. SEARCH METHODS: In January 2020, we searched CENTRAL, MEDLINE, Embase, six other databases, and two trials registers. We handsearched conference abstracts and checked reference lists of included studies. SELECTION CRITERIA: Randomized controlled trials (RCTs) or quasi-RCTs, including cross-over trials, comparing any type of mechanically assisted walking training (with or without body weight support) with no walking training or the same dose of overground walking training in children with cerebral palsy (classified as Gross Motor Function Classification System [GMFCS] Levels I to IV) 3 to 18 years of age. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: This review includes 17 studies with 451 participants (GMFCS Levels I to IV; mean age range 4 to 14 years) from outpatient settings. The duration of the intervention period (4 to 12 weeks) ranged widely, as did intensity of training in terms of both length (15 minutes to 40 minutes) and frequency (two to five times a week) of sessions. Six studies were funded by grants, three had no funding support, and eight did not report information on funding. Due to the nature of the intervention, all studies were at high risk of performance bias. Mechanically assisted walking training without body weight support versus no walking training Four studies (100 participants) assessed this comparison. Compared to no walking, mechanically assisted walking training without body weight support increased walking speed (mean difference [MD] 0.05 meter per second [m/s] [change scores], 95% confidence interval [CI] 0.03 to 0.07; 1 study, 10 participants; moderate-quality evidence) as measured by the Biodex Gait Trainer 2™ (Biodex, Shirley, NY, USA) and improved gross motor function (standardized MD [SMD] 1.30 [postintervention scores], 95% CI 0.49 to 2.11; 2 studies, 60 participants; low-quality evidence) postintervention. One study (30 participants) reported no adverse events (low-quality evidence). No study measured participation or quality of life. Mechanically assisted walking training without body weight support versus the same dose of overground walking training Two studies (55 participants) assessed this comparison. Compared to the same dose of overground walking, mechanically assisted walking training without body weight support increased walking speed (MD 0.25 m/s [change or postintervention scores], 95% CI 0.13 to 0.37; 2 studies, 55 participants; moderate-quality evidence) as assessed by the 6-minute walk test or Vicon gait analysis. It also improved gross motor function (MD 11.90% [change scores], 95% CI 2.98 to 20.82; 1 study, 35 participants; moderate-quality evidence) as assessed by the Gross Motor Function Measure (GMFM) and participation (MD 8.20 [change scores], 95% CI 5.69 to 10.71; 1 study, 35 participants; moderate-quality evidence) as assessed by the Pediatric Evaluation of Disability Inventory (scored from 0 to 59), compared to the same dose of overground walking training. No study measured adverse events or quality of life. Mechanically assisted walking training with body weight support versus no walking training Eight studies (210 participants) assessed this comparison. Compared to no walking training, mechanically assisted walking training with body weight support increased walking speed (MD 0.07 m/s [change and postintervention scores], 95% CI 0.06 to 0.08; 7 studies, 161 participants; moderate-quality evidence) as assessed by the 10-meter or 8-meter walk test. There were no differences between groups in gross motor function (MD 1.09% [change and postintervention scores], 95% CI -0.57 to 2.75; 3 studies, 58 participants; low-quality evidence) as assessed by the GMFM; participation (SMD 0.33 [change scores], 95% CI -0.27 to 0.93; 2 studies, 44 participants; low-quality evidence); and quality of life (MD 9.50% [change scores], 95% CI -4.03 to 23.03; 1 study, 26 participants; low-quality evidence) as assessed by the Pediatric Quality of Life Cerebral Palsy Module (scored 0 [bad] to 100 [good]). Three studies (56 participants) reported no adverse events (low-quality evidence). Mechanically assisted walking training with body weight support versus the same dose of overground walking training Three studies (86 participants) assessed this comparison. There were no differences between groups in walking speed (MD -0.02 m/s [change and postintervention scores], 95% CI -0.08 to 0.04; 3 studies, 78 participants; low-quality evidence) as assessed by the 10-meter or 5-minute walk test; gross motor function (MD -0.73% [postintervention scores], 95% CI -14.38 to 12.92; 2 studies, 52 participants; low-quality evidence) as assessed by the GMFM; and participation (MD -4.74 [change scores], 95% CI -11.89 to 2.41; 1 study, 26 participants; moderate-quality evidence) as assessed by the School Function Assessment (scored from 19 to 76). No study measured adverse events or quality of life. AUTHORS' CONCLUSIONS: Compared with no walking, mechanically assisted walking training probably results in small increases in walking speed (with or without body weight support) and may improve gross motor function (with body weight support). Compared with the same dose of overground walking, mechanically assisted walking training with body weight support may result in little to no difference in walking speed and gross motor function, although two studies found that mechanically assisted walking training without body weight support is probably more effective than the same dose of overground walking training for walking speed and gross motor function. Not many studies reported adverse events, although those that did appeared to show no differences between groups. The results are largely not clinically significant, sample sizes are small, and risk of bias and intensity of intervention vary across studies, making it hard to draw robust conclusions. Mechanically assisted walking training is a means to undertake high-intensity, repetitive, task-specific training and may be useful for children with poor concentration.

The effects of progressive resistance training on daily physical activity in young people with cerebral palsy: a randomised controlled trial.

PURPOSE: To examine if individualised resistance training increases the daily physical activity of adolescents and young adults with bilateral spastic cerebral palsy (CP). METHOD: Young people with bilateral spastic CP were randomly assigned to intervention or to usual care. The intervention group completed an individualised lower limb progressive resistance training programme twice a week for 12 weeks in community gymnasiums. The primary outcome was daily physical activity (number of steps, and time sitting and lying). Secondary outcomes included muscle strength measured with a one-repetition maximum (1RM) leg press and reverse leg press. Outcomes were measured at baseline, 12 weeks and 24 weeks. RESULTS: From the 36 participants with complete data at 12 weeks, there were no between-group differences for any measure of daily physical activity. There was a likely increase in leg press strength in favour of the intervention group (mean difference 11.8 kg; 95% CI -1.4 to 25.0). No significant adverse events occurred during training. CONCLUSIONS: A short-term resistance training programme that may increase leg muscle strength was not effective in increasing daily physical activity. Other strategies are needed to address the low-daily physical activity levels of young people with bilateral spastic CP. IMPLICATIONS FOR REHABILITATION: Progressive resistance training may increase muscle strength but does not lead to increases in daily physical activity of young people with bilateral spastic cerebral palsy (CP) and mild to moderate walking disabilities. Other strategies apart from or in addition to resistance training are needed to address the low daily physical activity levels of young people with bilateral spastic CP and mild to moderate walking disabilities.

Gross motor function is an important predictor of daily physical activity in young people with bilateral spastic cerebral palsy.

AIM: The aim of the study was to describe daily physical activity levels of adolescents and young adults with bilateral spastic cerebral palsy (CP) and to identify factors that help predict these levels. METHOD: Daily physical activity was measured using an accelerometer-based activity monitor in 45 young people with bilateral spastic CP (23 males, 22 females; mean age 18y 6mo [SD 2y 5mo] range 16y 1mo-20y 11mo); classified as Gross Motor Function Classification System (GMFCS) level II or III and with contractures of <20° at hip and knee. Predictor variables included demographic characteristics (age, sex, weight) and physical characteristics (gross motor function, lower limb muscle strength, 6min walk distance). Data were analyzed using the information-theoretic approach, using the Akaike information criterion (AIC) and linear regression. RESULTS: Daily activity levels were low compared with published norms. Gross Motor Function Measure Dimension-E (GMFM-E; walking, running, and jumping) was the only common predictor variable in models that best predicted energy expenditure, number of steps, and time spent sitting/lying. GMFM Dimension-D (standing) and bilateral reverse leg press strength contributed to the models that predicted daily physical activity. INTERPRETATION: Adolescents and young adults with bilateral spastic CP and mild to moderate walking disabilities have low levels of daily activity. The GMFM-E was an important predictor of daily physical activity.
