The Ability of Physical Performance Measures to Identify Fall Risk in Older Adults Living With Dementia: A Systematic Review and Meta-Analysis.

OBJECTIVES: To determine whether physical performance measures commonly used in clinical settings can discriminate fallers from nonfallers and predict falls in older adults with dementia. DESIGN: Systematic review and meta-analysis. SETTING AND PARTICIPANTS: Older adults with dementia residing in the community, hospitals, and residential care facilities. METHODS: MEDLINE, Embase, PsycINFO, CINAHL, SPORTDiscus, the Cochrane Library, and the PEDro databases were searched from inception until December 27, 2023 (PROSPERO registration number: CRD42022303670). Retrospective or prospective studies that evaluated the associations between physical performance measures and falls in older adults with dementia were included. A random effects model was used to calculate the standardized mean difference (SMD) and 95% CI for each physical performance measure between fallers and nonfallers. Sensitivity analyses were conducted on the longitudinal studies to determine the ability of physical performance measures to predict future falls. RESULTS: Twenty-eight studies were included in this review (n = 3542). The 5-time chair stand test [SMD = 0.23 (0.01, 0.45)], the Berg Balance Scale [SMD = -0.52 (-0.87, -0.17)], postural sway when standing on the floor [SMD = 0.25 (0.07, 0.43)] and on a foam surface [SMD = 0.45 (0.25, 0.66)], and the Short Physical Performance Battery total score [SMD = -0.46 (-0.66, -0.27)] could discriminate fallers from nonfallers. Sensitivity analyses showed that gait speed could predict future falls in longitudinal cohort studies [SMD = -0.29 (-0.49, -0.08)]. Subgroup analyses showed that gait speed [SMD = -0.21 (-0.38, -0.05)] and the Timed Up and Go test [SMD = 0.54 (0.16, 0.92)] could identify fallers staying in residential care facilities or hospitals. CONCLUSIONS AND IMPLICATIONS: The 5-time chair stand test, the Berg Balance Scale, postural sway when standing on the floor and a foam surface, and the Short Physical Performance Battery can be used to predict falls in older adults with dementia. Gait speed and the Timed Up and Go test can be used to predict falls in institutionalized older adults with dementia. Clinicians are recommended to use these physical performance measures to assess fall risk in older adults with dementia.

Association between fear of falling and falls following acute and chronic stroke: a systematic review with meta-analysis.

OBJECTIVES: To examine the association between falls and fear of falling in people with stroke and to evaluate the differences between patients with acute stroke and those with chronic stroke with regard to any such association. METHODS: Articles were searched in Medline, CINAHL, AMED, Embase, PsycINFO, Cochrane Library of Reviews and PEDro from inception until March 2023. Experimental, observational or explorative studies investigating the association between fear of falling and falls in people with stroke were included. Articles were screened by 2 independent reviewers. Data were extracted by an independent reviewer. RESULTS: A total of 26 reports were included in this review (n = 2863). Fear of falling, assessed by a single-question survey, was significantly associated with falls (relative risk = 1.44; 95% confidence interval (95% CI) = 1.22, 1.70; I2 = 0%) in people with acute stroke. Significant mean differences in fear of falling, based on the Falls Efficacy Scale (mean difference = 12.80; 95% CI = 1.81, 23.78; I² = 28%) and Activities-specific Balance Confidence Scale (mean difference = -9.99; 95% CI = -15.36, -4.62; I² = 57%), were also reported between fallers and non-fallers in people with chronic stroke. CONCLUSION: A small, but significant, association exists between falls and fear of falling in both acute and chronic stroke patients.

Development of the Social Motor Function Classification System for Children with Autism Spectrum Disorders: A Psychometric Study.

To examine reliability and validity of the new Social Motor Function Classification System for Children with Autism Spectrum Disorders (SMFCS-ASD). The SMFCS-ASD reliability was examined on 25 children (62.4 months SD 7.8) with ASD among six physical therapists. The validity study involved 1001 children (57.0 months, SD 9.9) with ASD using the gross motor scale (GMS) of the Peabody Developmental Motor Scales (PDMS-2). The indices of agreement and reliability across six examiners were moderate to substantial (Cohen's κ ≤ 0.65 and ICC > 0.90, all p < 0.001). The SMFCS-ASD was significantly correlated with the GMS of PDMS-2 (all rho from 0.61 to 0.76, p < 0.001). The SMFCS-ASD was reliable and significantly correlated with the GMS of the PDMS-2.

Development of Gross Motor Evaluation for Children Aged 18 to 42 Months.

PURPOSE: To test the reliability and validity of the gross motor items making up a new instrument, Hong Kong Comprehensive Assessment Scales for Toddlers (HKCAS-T) for quantifying gross motor development among children aged 18 to 42 months. METHODS: The 37 items were administered to 330 children, including 258 typically developing children and 72 children with gross motor delay. RESULTS: Rasch analyzes indicated that the fit statistics of the 37 items were within the acceptable range. The assessment was found able to differentiate between typically developing children and those with gross motor delay and among children of different ages. The raw score reliability (KR-20) was 0.94. CONCLUSION: The new instrument is a promising alternative for assessing young children's gross motor development.

Development and pilot evaluation of the Cognition domain of the Hong Kong Comprehensive Assessment Scales for Toddlers.

Purpose: To describe the development of the Cognition domain of the Hong Kong Comprehensive Assessment Scales for Toddlers (HKCAS-T).Methods: Participants included 345 toddlers aged 18-41 months, with 258 recruited from Maternal and Child Health Centers (MCHCs) and 87 with cognitive delay recruited from Child Assessment Centers (CACs). They were individually administered the 83-item pilot version by medical practitioners or educational psychologists between 2017 and 2019 in MCHCs and CACs in Hong Kong.Results: Rasch analysis results supported the unidimensionality of the pilot version, after removing six items. Analysis of covariance results indicated that both the 83-item version and the 77-item version could differentiate between children of different age groups, and children with typical development from children with cognitive delay. Internal consistency and interrater reliability were 0.90 or above.Conclusions: The Cognition domain of the HKCAS-T is a promising developmental assessment tool for the assessment of toddlers.

Effectiveness of a multidisciplinary parent training program for children with developmental disabilities: A single-blind randomized waitlist controlled trial.

This study aimed to evaluate the effectiveness of a multidisciplinary parent training program, Promoting Holistic Development of Young Kids (Poly Kids), using a single-blind randomized waitlist controlled design. The participants included 218 parents of children with developmental disabilities (DD) (intervention group = 107 and waitlist control group = 111). The primary outcomes were child learning, expressive language, fine and gross motor skills (based on individual assessment by respective blinded professionals), and parental reports of child behavior problems. The parents in the intervention group reported significantly lower child behavior problems (d = .34), higher child task motivation (d = .63), and lower parenting stress post-intervention (d = .25), while the children in the intervention group produced significantly more words post-intervention (d = .82). McNemar test results were significant for movement out of the clinical range in child behavior problems and cognitive skills in the intervention group, but not the control group. The results provided initial evidence on the effectiveness of this train-the-trainer program in supporting families with preschool children with DD in terms of child behavior problems, expressive language, cognitive skills, task motivation, and parenting stress.

Longitudinal Development of Segmental Trunk Control in Full Term and Preterm Infants- a Pilot Study: Part II.

Purpose: To explore the relationship between segmental trunk control and specific gross motor skills at 4, 8 and 12 months of (corrected) age in young infants.Methods: Thirty-one preterm infants and 30 full-term infants were recruited by convenience. All infants were tested using the Segmental Assessment of Trunk Control and the Alberta Infant Motor Scale at 4, 8 and 12 months of age.Results: The gross motor function in supine at 4 months and in the standing position at 12 months was significantly delayed in the preterm infants. Positive correlations were found between segmental trunk control levels and specific motor skills in prone, supine, sitting and standing positions at 8 and 12 months of age.Conclusion: This report was the first to demonstrate the association between segmental trunk control and specific gross motor skills in young infants. This new information provides clinicians with greater understanding about infant development.

Longitudinal Development of Segmental Trunk Control in Full Term and Preterm Infants- a Pilot Study: Part I.

Purpose: No previous study examined trunk control development in preterm infants. The present study examined the longitudinal development of segmental trunk control from 4 to 12 months of (corrected) age in preterm infants in comparison with full-term infants.Methods: Thirty-one preterm infants and 30 full-term infants were recruited. All infants were tested monthly using the Segmental Assessment of Trunk Control and the Alberta Infant Motor Scale at 4, 8 and 12 months of age.Results: Segmental trunk control development was significantly delayed in the preterm infants. Statistically significant positive correlations were found between trunk control status and gross motor skills.Conclusion: This was first study showing that segmental trunk control development was significantly different in preterm infants. Segmental trunk control and gross motor performance were coupled in young infants. A dual focus on training upright trunk control and specific motor skills may maximise therapy outcomes for infants with motor delay.

Reliability, validity and minimal detectable change of 2-min walk test and 10-m walk test in frail older adults receiving day care and residential care.

BACKGROUND: The psychometric properties of the 2-min walk test (2MWT) and 10-m walk test (10MeWT) for frail older adults are unclear. AIMS: To determine the test-retest and inter-rater reliability, construct and known-group validity, and minimal detectable change at 95% level of confidence (MDC95) of these walk tests in frail older adults receiving day care and residential care services. METHODS: A cross-sectional study with repeated measures was conducted on frail older adults who could walk independently for at least 15 m. The participants completed the 2MWT and 10MeWT on three separate occasions over a 2-week period under two independent assessors. RESULTS: Forty-four frail older adults were examined. Excellent test-rest (ICC = 0.95-0.99) and inter-rater reliability (ICC = 0.95-0.97) were shown in both walk tests. Good to strong correlations were found between the walk tests and 6-min walk test (r = 0.89-0.92), Elderly Mobility Scale (r = 0.56-0.57), Berg Balance Scale (r = 0.66-0.66) and Modified Barthel Index (r = 0.55-0.59). The MDC95 were 7.7 m in the 2MWT and 0.13 m/s in the 10MeWT. DISCUSSION: Although the walking performances of the day care and residential care participants were similar, the validity of the walk tests was different between these two subgroups. CONCLUSIONS: The 2MWT and 10MeWT are reliable and valid measures in evaluating the walking performances of frail older adults. The MDC95 of the walk tests has been recommended.

Relationship between segmental trunk control and gross motor development in typically developing infants aged from 4 to 12 months: a pilot study.

BACKGROUND: Trunk control is generally considered to be related to gross motor development. However, this assumption has not been validated with clinical data. This pilot study was the first of its kind to examine the longitudinal development of segmental trunk control and gross motor development from 4 to 12 months of age in typically developing full-term infants. METHODS: A convenience cohort of 20 healthy full-term infants (mean gestation = 39.0 weeks, SD 1.2; mean birthweight = 2975.0 g, SD 297.0; males = 10) was recruited. All study infants were tested and scored monthly by independent assessors using the Segmental Assessment of Trunk Control and the Alberta Infant Motor Scale from 4 to 12 months of age. RESULTS: A developmental trend of segmental trunk control was found in the infants. Static vertical upright trunk control developed prior to active and reactive control. Statistically significant correlations were found between trunk control status and gross motor development mainly in prone and sitting positions from 8 months of age onwards (all p < 0.004, Spearman's r ranged from 0.644 to 0.798). CONCLUSIONS: This pilot study provides preliminary clinical evidence to support the inter-dependency between vertical upright trunk control and gross motor development in young infants, particularly as upright functional skills are gained. This suggests that a dual focus on training upright trunk control alongside gross motor skills could be of benefit in the treatment of infants with movement disorders.
