Reliability and sensitivity to change of the timed standing balance test in children with down syndrome

The effectiveness of dance movement therapy for individuals with Down syndrome: a pilot randomised controlled trial

BACKGROUND

Individuals with Down syndrome (DS) exhibit deficits in static and dynamic balance abilities and maladaptive functions. This study aimed to determine the effectiveness of dance movement therapy (DMT) group intervention in individuals with DS.

METHODS

The 31 participating individuals with DS, aged 5-29 years, were randomly divided into intervention (n = 16) and control (n = 15) groups. Posturography was used for static balance measurement, timed up and go test for dynamic balance measurement and the Achenbach System of Empirically Based Assessment (ASEBA) questionnaire for adaptive function and behavioural problem measurement in participants before and after the DMT interventions. The intervention group underwent 60-min DMT intervention once a week for 10 times, while the control group had usual daily activities.

RESULTS

The results revealed a statistically significant difference and large effect sizes in dynamic balance [(f(1, 29) = 4.52, P = 0.04, η_p   ² = 0.14)] in the intervention group compared with the control group. There were no statistically significant differences in static balance and ASEBA scores between the groups.

CONCLUSIONS

This study found that the DMT interventions helped to improve the dynamic balance in individuals with DS.

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.

Current Trends in Pediatric Physical Therapy Practice for Children With Down Syndrome

BACKGROUND

Physical therapists (PTs) have a broad range of approaches to the management of Down syndrome (DS).

PURPOSE

To examine the breadth of physical therapy practice for children with DS.

METHODS

A survey was distributed to 1000 randomly selected members of the Academy of Pediatric Physical Therapy.

DATA ANALYSIS

Responses were categorized into 13 thematic subcategories and 3 International Classification of Functioning, Disability and Health (ICF) subcategories.

RESULTS AND DISCUSSION

One hundred eight PTs participated. Joint stability and alignment were the most common physical therapy-related problem. Functional movement was the most common physical therapy intervention. Most clinicians identified and treated at the ICF level of body functions and structure. Multiple assessment tools were used and tended to include norm-referenced tests. There was diversity of interventions with varying amounts of supporting evidence.

CONCLUSIONS

PTs manage children with DS for a wide variety of needs with a variety of interventions.

Foot Structure in Boys with Down Syndrome

Introduction and Aim

Down syndrome (DS) is associated with numerous developmental abnormalities, some of which cause dysfunctions of the posture and the locomotor system. The analysis of selected features of the foot structure in boys with DS versus their peers without developmental disorders is done.

Materials and Methods

The podoscopic examination was performed on 30 boys with DS aged 14-15 years. A control group consisted of 30 age- and gender-matched peers without DS.

Results

The feet of boys with DS are flatter compared to their healthy peers. The hallux valgus angle is not the most important feature differentiating the shape of the foot in the boys with DS and their healthy peers. In terms of the V toe setting, healthy boys had poorer results.

Conclusions

Specialized therapeutic treatment in individuals with DS should involve exercises to increase the muscle strength around the foot joints, enhancing the stabilization in the joints and proprioception. Introducing orthotics and proper footwear is also important. It is also necessary to monitor the state of the foot in order to modify undertaken therapies.
