Investigation of the timed‘Up & Go’test in children

The timed‘Up & Go’test (TUG) is a test of basic or functional mobility in adults which has rarely been used in children. Functional mobility was defined for this study as an individuals ability to manoeuvre his or her body capably and independently to accomplish everyday tasks. Reliability and validity of TUG scores were examined in 176 children without physical disabilities (94 males, 82 females; mean age 5y 9mo [SD 1y 8mo]; range 3 to 9y) and in 41 young people with physical disabilities due to cerebral palsy or spina bifida (20 males, 21 females; mean age 8y 11mo [SD 4y 3mo], range 3 to 19y). Mean TUG score for children without physical disability was 5.9s (SD 1.3). Reliability of the TUG test was high, with intraclass correlation coefficients (ICC) of 0.89 within session, and 0.83 for test‐retest reliability. Mean score of the group aged 3 to 5 years was significantly higher (6.7s SD 1.2) than that of the older group (5.1s, SD 0.8;p=0.001). Scores in the younger group reduced significantly over a 5‐month follow‐up period (p=0.001), indicating that the TUG was responsive to change. Within‐session reliability of the TUG in young people with disabilities was very high (ICC=0.99). There were significant differences in TUG scores between children classified at levels I, II, and III of the Gross Motor Function Classification System (p=0.001). TUG scores showed a moderate negative correlation with scores on the Standing and Walking dimensions of the Gross Motor Function Measure (n=22, rho=‐0.52,p=0.012). There was no significant difference in TUG scores between typically developing male and female children. The TUG can be used reliably in children as young as 3 years using the protocol described in this paper. It is a meaningful, quick, and practical objective measure of functional mobility. With further investigation, the TUG is potentially useful as a screening test, an outcome measure in intervention studies for young people with disabilities, a measure of disability, and as a measure of change in functional mobility over time.

Thoracic Kyphosis Affects Spinal Loads and Trunk Muscle Force

Background and Purpose Patients with increased thoracic curvature often come to physical therapists for management of spinal pain and disorders. Although treatment approaches are aimed at normalizing or minimizing progression of kyphosis, the biomechanical rationales remain unsubstantiated. Subjects Forty-four subjects (mean age [±SD]=62.3±7.1 years) were dichotomized into high kyphosis and low kyphosis groups. Methods Lateral standing radiographs and photographs were captured and then digitized. These data were input into biomechanical models to estimate net segmental loading from T2–L5 as well as trunk muscle forces. Results The high kyphosis group demonstrated significantly greater normalized flexion moments and net compression and shear forces. Trunk muscle forces also were significantly greater in the high kyphosis group. A strong relationship existed between thoracic curvature and net segmental loads (r =.85–.93) and between thoracic curvature and muscle forces (r =.70–.82). Discussion and Conclusion This study provides biomechanical evidence that increases in thoracic kyphosis are associated with significantly higher multisegmental spinal loads and trunk muscle forces in upright stance. These factors are likely to accelerate degenerative processes in spinal motion segments and contribute to the development of dysfunction and pain.

Hand-held dynamometry for muscle strength measurement in children with cerebral palsy.

The aim of this study was to investigate the reliability of hand‐held dynamometry for measuring isometric lower‐limb muscle strength in children with cerebral palsy (CP). Twentythree children (14 males, nine females) with CP (spastic diplegia; Gross Motor Function Classification System Levels I‐III) aged 5 years 7 months to 14 years 5 months (mean 9y 6mo [SD 2y 8mo]) attended two test sessions 1 week apart. A ‘make’ test, using a gradual build‐up of force to a maximum isometric contraction, was employed and peak values were normalized to body weight for analyses. Within‐session reliability was high with an intraclass correlation coefficient (ICC) of 1,1>0.79 for all muscle groups, and there was acceptable between‐session reliability ICC>0.70 and measurement errors for hip flexors and extensors (measured in supine), knee flexors and extensors, and ankle dorsiflexors (with stabilization). Within‐ and between‐session reliability was poor (ICC<0.70) for hip extensors (in prone), knee extensors (20° flexion), ankle dorsiflexors (without stabilization), and ankle plantarflexors. Measurement error differed in each test and across limbs, with stabilization producing inconsistent reliability outcomes. Changes in strength measurements in children with CP should take into account measurement error for particular muscle groups. Changes should be determined for separate muscle groups and limbs, and reported relative to body weight. Different testing positions may be required for greater reliability.

Use of the one-legged hyperextension test and magnetic resonance imaging in the diagnosis of active spondylolysis

Background: Active spondylolysis is an acquired lesion in the pars interarticularis and is a common cause of low back pain in the young athlete. Objectives: To evaluate whether the one-legged hyperextension test can assist in the clinical detection of active spondylolysis and to determine whether magnetic resonance imaging (MRI) is equivalent to the clinical gold standard of bone scintigraphy and computed tomography in the radiological diagnosis of this condition. Methods: A prospective cohort design was used. Young active subjects with low back pain were recruited. Outcome measures included clinical assessment (one-legged hyperextension test) and radiological investigations including bone scintigraphy (with single photon emission computed tomography (SPECT)) and MRI. Computed tomography was performed if bone scintigraphy was positive. Results: Seventy one subjects were recruited. Fifty pars interarticulares in 39 subjects (55%) had evidence of active spondylolysis as defined by bone scintigraphy (with SPECT). Of these, 19 pars interarticulares in 14 subjects showed a fracture on computed tomography. The one-legged hyperextension test was neither sensitive nor specific for the detection of active spondylolysis. MRI revealed bone stress in 40 of the 50 pars interarticulares in which it was detected by bone scintigraphy (with SPECT), indicating reduced sensitivity in detecting bone stress compared with bone scintigraphy (p  =  0.001). Conversely, MRI revealed 18 of the 19 pars interarticularis fractures detected by computed tomography, indicating concordance between imaging modalities (p  =  0.345). There was a significant difference between MRI and the combination of bone scintigraphy (with SPECT)/computed tomography in the radiological visualisation of active spondylolysis (p  =  0.002). Conclusions: These results suggest that there is a high rate of active spondylolysis in active athletes with low back pain. The one-legged hyperextension test is not useful in detecting active spondylolysis and should not be relied on to exclude the diagnosis. MRI is inferior to bone scintigraphy (with SPECT)/computed tomography. Bone scintigraphy (with SPECT) should remain the first-line investigation of active athletes with low back pain followed by limited computed tomography if bone scintigraphy is positive.

Effect of test position on pelvic floor muscle assessment

The aims of this study were to analyse the effect of different body positions on pelvic floor muscle (PFM) assessment using digital muscle testing, manometry and transabdominal ultrasound. In addition, subject acceptance of each testing position was recorded. Subjects were 20 womens health physiotherapists. The testing protocol included the best of three maximum voluntary contractions tested in each of four positions (crook lying, supine, sitting and standing). Significant differences in muscle strength and subject acceptance between positions were found with each tool, most often between lying and upright positions. Digital muscle testing and vaginal squeeze-pressure scores were highest in the lying position, and vaginal resting pressure and transabdominal ultrasound scores were highest in the standing position. Subjects preferred the lying positions for internal examinations. The clinical significance of these differences and the reasons for these variations require further investigation.

Content of clinical supervision sessions for nurses and allied health professionals: A systematic review

Purpose – The purpose of this paper is to evaluate the current evidence regarding the content of clinical supervision for nursing and allied health professionals.Design/methodology/approach – The authors searched CINAHL, Medline, PsychINFO and Cochrane Database. Studies were included if the participants involved were nursing, medical or allied health practitioners, but not students, and if the studies contained discussion regarding the content of clinical supervision. Critical analysis of the articles was carried out by two independent researchers to ensure consistency and thematic analysis was applied.Findings – Twenty included articles were in three main categories: cross‐sectional studies (n=9), including interview, survey and focus group methods of data collection; literature reviews (n=2); and nine published opinion pieces. Themes related to the content of clinical supervision that were identified were reflective practice; task oriented content; diversity of content; and stress management. The result...

The Influence of Otolith Dysfunction on the Clinical Presentation of People With a Peripheral Vestibular Disorder

Background and Purpose Traditional vestibular function testing has measured horizontal semicircular canal function only. Otolith function tests have recently been developed, but their clinical significance has not been determined. The purpose of this study was to investigate the influence of otolith dysfunction on the clinical presentation of individuals with a peripheral vestibular disorder. Subjects and Methods Twenty-one subjects with loss of horizontal semicircular canal function only and 37 subjects with combined loss of horizontal semicircular canal and otolith organ function were recruited. All subjects received a comprehensive clinical assessment, including self-report questionnaires and measures of balance performance. Results No significant differences were identified between subjects with or without otolith dysfunction with respect to symptom severity, self-perceived handicap, functional limitations, or balance performance. Discussion and Conclusion Otolith dysfunction does not significantly influence the clinical presentation of individuals with a peripheral vestibular disorder. Other factors, including symptom severity, may be more influential.

A family-centred model of care in paediatric speech-language pathology

Abstract Developments in paediatric models of care support family-centred practice (FCP); however, there is limited evidence for its use in speech-language pathology. This randomized controlled study examined whether parent satisfaction with FCP (n = 10) was greater than with usual practice (UP; n = 10) over 14 weeks for children with mild–moderate speech and/or language disorders. The FCP included parental goal decision-making; greater parent responsibility for clinic therapy tasks; and two home visits. There was a non-significant trend for the FCP group to have a higher mean score for the “Providing specific information” scale of the Measures of Process of Care. Goals for the FCP and UP groups were respectively targeted towards the Activities and Participation or the Body Function components of the International Classification of Functioning, Disability and Health–Children and Youth. While there were no significant differences between groups for speech/language outcomes post-intervention; it is clinically interesting that more children in the FCP group improved on the Renfrew Action Picture Test than the UP group. This study did not demonstrate a significant benefit for FCP over a relatively short timeframe in a small sample of children. Further research is warranted to determine if there is evidence for the use of FCP in speech-language pathology.

Comparison of two fall risk assessment tools (FRATs) targeting falls prevention in sub-acute care

FRATs are designed to identify both persons at high risk of falls and to allow for cost-effective targeting of fall prevention strategies. This study compares two FRATs (BHS FRAT and TNH-STRATIFY) for accuracy of predicting falls and targeting of fall prevention strategies in a sub-acute hospital. Comparisons of retrospective audit data over two periods (use of the BHS-FRAT; post TNH-STRATIFY implementation) were used in the evaluation (n=362). Inter-rater reliability of the TNH-STRATIFY was evaluated from independent assessment by two nurses for 30 sub-acute patients and using intraclass correlation coefficient (ICC(2,1)). Event rate (ER) and standard measures of predictive accuracy were calculated for both FRATs. The proportions of patients with documented fall prevention strategies addressing identified fall risk factors were compared between audit phases. The TNH-STRATIFY had high inter-rater reliability (ICC(2,1)=0.96). The BHS-FRAT and TNH-STRATIFY demonstrated poor predictive accuracy using recommended high risk cut-off scores, with low specificity(ER) (0.07 and 0.13 respectively) and very low Youden Index(ER) (0.04 and 0.07 respectively), although these measures improved using modified cut-off scores. Positive and negative predictive values were moderate for the BHS-FRAT (0.51, 0.64) and TNH-STRATIFY (0.52, 0.61). The falls rate and proportion of recurrent fallers did not change between audit phases. Implementation rates for prevention strategies for key risk factors were higher following implementation of the TNH-STRATIFY. The results indicated that the TNH-STRATIFY, combined with associated nursing care plan falls documentation, improved the targeting of prevention strategies for key risk factors such as cognitive impairment, incontinence and mobility impairment.
