Efficacy of ankle-foot orthoses on gait of children with cerebral palsy: systematic review of literature.

Purpose: To perform a literature review evaluating the quality of current research on the influence of ankle-foot orthoses (AFOs) on gait in children with cerebral palsy (CP). Methods: A qualitative systematic review of intervention studies including the following words/phrases in the title/abstract: children with CP, AFO, gait and inferential statistical analysis, and outcomes related to gait. Databases searched included PubMed, Cochrane Library, PEDro, OTSeeker, Lilacs, and Scielo. Level of evidence was graded using the PEDro Scale. Results: Two between-group and 18 within-group studies met the inclusion criteria indicating a low level of evidence. Between-group studies each scored 4 on the PEDro Scale, and 17 within-group studies scored 3 and 1 scored 2, indicating low quality. Standard terminology for AFOs was not used and only 6 studies described functional status using appropriate instruments. Conclusions: Studies using high quality methods are still needed to support evidence-based decisions regarding the use of AFOs for this population.

Treadmill training for ataxic patients: a single-subject experimental design

Objective: To investigate changes in gait quality, balance and mobility associated with treadmill training for ataxic individuals. Design: Single-subject ABA design. Baseline phases (A) lasted three weeks and intervention (B) lasted four weeks. Setting: University rehabilitation clinic. Subjects: A woman (25 years) and a man (53 years) with chronic ataxia due to head trauma. Intervention: Three 20-minute treadmill training sessions each week with progression in velocity and step length. Main measures: Rivermead Visual Gait Assessment, Timed Up and Go, time to complete a balance task, walking speed, cadence, and stride length assessments three times a week during the 10 weeks. Data were analysed with the celeration line technique and two standard deviation band. Results: Both individuals demonstrated gains in all parameters over initial baseline and subsequent phases, with performance increases ranging from 26% to 233% when first and last assessments were compared. Significantly superior effects of treadmill training over baseline conditions on cadence were detected (P<0.05). Gains in walking speed were not significantly better during intervention, but intervention withdrawal produced deceleration of performance gains. Gains in Timed Up and Go, step length and balance were not consistent and were possibly caused by a learning effect of the association between repeated testing and treadmill training. Rivermead Visual Gait Assessment gains reached significance only for subject 2 (P<0.05), probably because of increased variability of performance of subject 1. Results suggest that the association between repeated testing and treadmill training might have been responsible for the observed gains in the two ataxic patients.

Relation between hand function and gross motor function in full term infants aged 4 to 8 months

BACKGROUND In children, reaching emerges around four months of age, which is followed by rapid changes in hand function and concomitant changes in gross motor function, including the acquisition of independent sitting. Although there is a close functional relationship between these domains, to date they have been investigated separately. OBJECTIVE To investigate the longitudinal profile of changes and the relationship between the development of hand function (i.e. reaching for and manipulating an object) and gross motor function in 13 normally developing children born at term who were evaluated every 15 days from 4 to 8 months of age. METHOD The number of reaches and the period (i.e. time) of manipulation to an object were extracted from video synchronized with the Qualisys(r) movement analysis system. Gross motor function was measured using the Alberta Infant Motor Scale. ANOVA for repeated measures was used to test the effect of age on the number of reaches, the time of manipulation and gross motor function. Hierarchical regression models were used to test the associations of reaching and manipulation with gross motor function. RESULTS RESULTS revealed a significant increase in the number of reaches (p<0.001), the time of manipulation (p<0.001) and gross motor function (p<0.001) over time, as well as associations between reaching and gross motor function (R2=0.84; p<0.001) and manipulation and gross motor function (R2=0.13; p=0.02) from 4 to 6 months of age. Associations from 6 to 8 months of age were not significant. CONCLUSION The relationship between hand function and gross motor function was not constant, and the age span from 4 to 6 months was a critical period of interdependency of hand function and gross motor function development.

Terminology of Pelvic Floor Muscle Function in Women With and Without Urinary Incontinence: A Systematic Review

Background Pelvic floor muscle function (PFMF) is a target of the physical therapist intervention for women with urinary incontinence (UI). However, possible variations in PFMF terminology might hamper communication among researchers and health care professionals in Womens Health. Objective The objective of this study was to investigate the terminology of PFMF regarding clear terms, conceptual definitions, and operational definitions. Data Sources Data sources include PUBMED, CINAHL, LILACS, and SCIELO. Study Selection Observational studies investigating any PFMF in women with or without UI, published in English, Spanish, or Portuguese from 2005 through 2017, were considered. Data Extraction The risk of bias was assessed by a questionnaire on the quality of observational studies. Data on terminology were extracted as terms, conceptual definitions, and operational definitions of PFMF and were synthesized according to key words, key ideas, and key operationalization, respectively. Consistencies and variations were identified for the most frequently investigated PFMF. Data Synthesis Sixty-four studies were included, and a low risk of bias was identified. All studies presented terms and operational definitions of PFMF, but only 29.7% presented conceptual definitions of those terms. One hundred ninety-six different terms referred to PFMF. According to similarities in terminology, 161 PFMF terms could be grouped under 26 terms; the other 35 were left ungrouped. Therefore, a total of 61 different PFMF terms were identified in the literature. Limitations A limitation in the study was that only observational studies were included. Conclusions A large variation in PFMF terminology was identified, precluding data gathering and meta-analysis. The lack of use of standardized terminology delays the progress of scientific knowledge and evidence-based practice dissemination. Efforts toward creating a collaborative, consensual terminology based on a sound framework are necessary.
