Multi-directional reach test in South Asian children: Normative reference scores from 5 year to 12 years old

Psychometric properties of functional postural control tests in children: A systematic review

BACKGROUND

Postural control deficits are one of the most common impairments treated in pediatric physiotherapeutic practice. Adequate evaluation of these deficits is imperative to identify postural control deficits, plan treatment and assess efficacy. Currently, there is no gold standard evaluation for postural control deficits. However, the number of studies investigating the psychometric properties of functional pediatric postural control tests has increased significantly.

OBJECTIVE

To facilitate the selection of an appropriate pediatric functional postural control test in research and clinical practice.

METHODS

Systematic review following the PRISMA guidelines. PubMed, Web of Science and Scopus were systematically searched (last update: June 2022; PROSPERO: CRD42021246995). Studies were selected using the PICOs-method (pediatric populations (P), functional assessment tools for postural control (I) and psychometric properties (O). The risk of bias was rated with the COSMIN checklist and the level of evidence was determined with GRADE. For each test, the postural control systems were mapped, and the psychometric properties were extracted.

RESULTS

Seventy studies investigating 26 different postural control tests were included. Most children were healthy or had cerebral palsy. Overall, the evidence for all measurement properties was low to very low. Most tests (95%) showed good reliability (ICC>0.70), but inconsistent validity results. Structural validity, internal consistency and responsiveness were only available for 3 tests. Only the Kids-BESTest and FAB covered all postural control systems.

CONCLUSION

Currently, 2 functional tests encompass the entire construct of postural control. Although reliability is overall good, validity results depend on task, age and pathology. Future research should focus on test batteries and should particularly explore structural validity and responsiveness in different populations with methodologically strong study designs.

Reference values of postural balance in preschoolers: Age and gender differences for 4-5 years old Tunisian children

BACKGROUND

Preschool age is a critical stage of postural balance development. Posturography normative data during this age are crucial for surveillance of postural balance and for the timely diagnosis of any dysfunction. The aim of this study was to provide normative data, specific to Tunisian preschoolers, according to age and gender, and to examine gender- and age-related differences in postural balance.

RESEARCH QUESTION

Are there postural balance gender- and age-related differences in Tunisian preschoolers?

METHODS

The study included 410 (205 boys and 205 girls) preschool children aged between 4- and 5-year-old selected within a large geographic area of Tunisia. Postural balance was assessed using a stabilometric platform under 4 sensory conditions. The mean center of pressure velocity (CoP-V) parameter was selected for analysis. Differences between gender and age groups were analysed using the Mann-Whitney U. Normative data were expressed in percentiles.

RESULTS

Significant gender effect was found in conditions where sensory inputs are most challenged with a significantly smaller mean CoP-V in girls compared to boys (p < 0.05). Moreover, 5-year-old children had significantly better postural balance than 4-year-old ones in almost all conditions (p < 0.05).

SIGNIFICANCE

The normative data established for Tunisian preschoolers provide useful comparative data for pediatricians, teachers and coaches for the early evaluation and monitoring of postural balance during this age. Gender and age-related differences should be considered in this population.

Positive-word stimuli via a smartphone application have no immediate-term effects on multi-directional reach ability in standing position: a randomized controlled trial

OBJECTIVES

The purpose of the study was to examine the immediate-term effect of positive-word stimuli via a smartphone application on the multi-directional reach ability in standing position in young adults.

METHODS

This study was an immediate-term, assessor-blinded, two-arm, parallel-group, randomized controlled trial among young adults recruited from one university in Japan. Participants were randomly assigned to the experimental group or control group using a computer-based random number-generating programme. Participants of the experimental group used an application on iPhone and watched 3-min videos displaying positive-word stimuli. This application repeatedly displayed positive-word stimuli every 5 s. The participants of the control group used an application on iPhone and watched the same videos as in the experimental group. However, a positive-word stimulus did not appear in the videos. The primary outcome was the multi-directional reach test (MDRT) from baseline to immediately after the intervention protocol.

RESULTS

Among the 62 randomized participants (experimental group, n = 31; control group, n = 31), 62 (100%) completed the MDRT immediately after the intervention protocol. There were no differences in mean group change values in MDRT between the experimental and control groups.

CONCLUSIONS

Among young adults, positive-word stimuli via a smartphone application did not significantly improve multi-directional reach ability in standing position. These findings do not support the superiority of this intervention among young adults. Trial Registration: Clinicaltrials.gov, NCT03546218.

The multi-directional reach test in children with Down syndrome

Objective:

This study investigated the limits of stability (LOS) and the movement patterns during reaching by applying the Multi-Directional Reach Test (MDRT) in children with Down syndrome (DS) aged 7–12 years old.

Methods:

Thirty children with DS and 30 age and gender typical development (TD) matched children, aged 7–12 years old were recruited. Each child was asked to reach as far as possible during standing in four directions using a self-selected movement pattern. The movement patterns were classified by two experienced pediatric physical therapists.

Results:

The reach distance in children with DS aged 7–9 years old was significantly shorter than TD children aged 7–9 years old for the forward and backward directions. Also, the reach distance in DS children aged 7–9 years old was significantly smaller than that of TD children aged 10–12 years old for all directions. For children with DS aged 10–12 years old, the reach distance was significantly less than that of TD children only in the backward direction. All children with DS in this study adopt a hip and mixed strategy during forward and backward reaching. In contrast, TD children adopt an adult-like movement pattern.

Conclusion:

The boundary of stability in an anteroposterior (AP) direction of children with DS aged 7–12 years old was lesser than the matched TD children, especially for the backward direction. These findings may assist therapists in detecting postural control and balance problems in children with DS.

Relationships between lower extremity strength and the multi-directional reach test in children aged 7 to 12 years

Objective

This study investigates the relationships between the Multi-Directional Reach Test (MDRT) and lower extremity strength in typical children.

Methods

The MDRT including forward, backward, leftward, and rightward directions was measured in 60 children aged between 7 and 12 years old with typical development. The lower extremity muscle groups were measured using a hand-held dynamometer.

Results

The reaching score in each direction had positive relationships with the strengths of several lower extremity muscle groups ( r = 0 . 26 to 0 . 52 , p < 0 . 05 ) . Only the strengths of the hip flexor and knee flexor muscles significantly correlated with the MDRT scores in all directions ( r = 0 . 26 to 0 . 50 , p < 0 . 05 ) .

Conclusion

This study highlights the strength of the hip and knee flexor muscle groups as being important domain to control balance in all directions. These findings may be used for therapists in planning a balance program to improve the limits of stability.
