The Psychometric Properties of the Short Physical Performance Battery to Assess Physical Performance in Older Adults: A Systematic Review

BACKGROUND

Maintaining physical performance in older age is critical. The Short Physical Performance Battery (SPPB) is one of many tools available to measure physical performance in older people.

PURPOSE

Describe the psychometric properties of the SPPB.

METHODS

Using a systematic review methodology, quantitative studies addressing the validity, reliability, and sensitivity of the SPPB in populations 60 years or older were included. We searched 8 databases: MEDLINE, CINAHL, Cochrane, Ageline, Amed, Embase, Scopus, and Emcare, as well as gray literature. Two researchers independently screened, appraised, and extracted data from the literature, following which a descriptive synthesis was undertaken.

RESULTS

Twenty-eight studies with varying methodological quality were included. Floor and ceiling effects were reported in 4 studies, generally related to very high or very low functioning adults. Nineteen studies investigated validity with varying correlations between the SPPB and other physical performance assessment tools. Ten studies reported good to excellent reliability (intraclass correlation coefficient ranging 0.82-0.92). Minimum detectable change indicates low sensitivity (ranging 0.7-3.42).

DISCUSSION

Evidence from the literature indicates that the SPPB is a reliable and valid measure of physical performance in adults older than 60 years. However, the SPPB has a narrow scope and is most appropriate for frail older adults who can ambulate and are cognitively able to follow instructions. It has limited applicability for specific populations such as people with dementia who have difficulty following instructions. Targeted training for users may improve its usability and success in clinical practice.

CONCLUSIONS

Clinicians should be mindful that while the SPPB has good validity and reliability, it has limited applicability for people with dementia and is not particularly sensitive to change. In practice, this means that it provides a good snapshot of a client's physical performance compared with the rest of the older population; it is less useful for tracking changes to physical performance over time.

Occupational therapists and physiotherapists weighing up the dignity of risk for people living with a brain injury: grounded theory

PURPOSE

Following a brain injury survivors may have physical, or cognitive changes or behaviours which bring safety risks into play when engaging in activities. Therapists experience tensions in enabling the dignity of participation in the context of managing risk.

MATERIALS AND METHODS

Ten occupational therapists and seven physiotherapists participated in a grounded theory study utilising semi-structured in-depth interviews to explore the tensions between dignity and management of safety risks. Data were analysed using constant comparative method and a process of moving from open coding to categories to theory development.

RESULTS

The process of weighing up was central to the therapists' approach to supporting dignity while managing risk. Respecting dignity itself is placed at risk when preventing harm is weighted higher than living a full life. Therapists who use weighing up as a process that respects dignity place greater value on the principles of respecting autonomy and promotion of justice for people with a brain injury.

CONCLUSION

Rather than taking control and attempting to minimise risk therapists who privilege the perspective of the client, and provide opportunities for learning through failure or success, enable clients to live a full life.IMPLICATIONS FOR REHABILITATIONEnsuring that clients with brain injury are safe often requires therapists to exercise control and remove agency thus removing the rights of the client to the dignity of risk and living a full life.Providing opportunities within rehabilitation for clients to experience failure and success enables learning and thereby support dignity.Privileging the client perspective provides clients the dignity of living a normal life.

Are group identity and sense of belonging relevant for group pain management programmes? An exploratory pilot study

Introduction

Cognitive Behaviour Therapy (CBT)-based programmes for chronic pain are often conducted in groups, most likely for time and cost efficiencies. However, there has been very little investigation of the role that the group itself, and particularly the processes occurring within the group, may play in individual outcomes. The objective of this study was to explore whether social group processes were relevant to key treatment outcomes of group CBT for chronic pain.

Method

Data were collected from 15 groups (N = 118) undertaking a pain management programme in a tertiary setting. Intraclass correlations were computed to determine any clustering of outcomes in groups, and linear mixed modelling analysis explored pre-registered hypotheses of associations between treatment outcomes and the social group processes of Group Identification and Sense of Belonging.

Results

A weak association between early identification with the group and changes in pain-related disability was shown. In addition, an enhanced global Sense of Belonging was associated with increased pain self-efficacy.

Conclusion

These associations, in a programme that had not been designed to address group processes, suggest that their relevance is worth further investigation, particularly in group programmes that do focus on the social consequences of chronic pain. Future studies should investigate whether manipulation of social group processes within a CBT-based pain programme enhances pain-related outcomes and improves the overall well-being of people with chronic pain.

Setting up girls for success in fundamental motor skills: The role of balance in 8-10 year olds

The purpose of this study was to explore the relationship between postural control and fundamental motor skills in girls. An observational cross-sectional study was conducted in 47 girls, aged 8-10 years. Postural control (postural sway centre of pressure) was evaluated during tandem stance, leading with dominant and non-dominant limbs with eyes open and closed, using an AMTI force platform. Fundamental motor skills were assessed using the Test of Gross Motor Development 2nd Edition, examining total, locomotor and object control scores. Data were analysed using linear regression, adjusted for body mass index percentile and household income. For locomotor skills, significant relationships were found with a number of postural sway outcomes for adjusted and unadjusted analyses (r - 0.287 to r - 0.425, p ≤ 0.042). Total motor skill score was significantly related to postural sway in the tandem dominant eyes closed condition for unadjusted and adjusted analyses (r ≥ -0.294, p ≤ 0.04). In conclusion, our findings indicate that postural control may be important for fundamental motor skill proficiency and movement quality in pre-adolescent girls, particularly for locomotor skills. Our study provides evidence supporting the clinical practice of assessing postural control in girls presenting with motor skill deficits.

Improvement in postural alignment is associated with recovery of mobility after complex acquired brain injury: An observational study

PURPOSE

Determine how mobility changes over 6 months in people unable to walk at 8-weeks post-Acquired Brain Injury (ABI); if there is an association over time between postural alignment and mobility post-ABI; and if alignment after ABI becomes closer to healthy alignment over time.

METHODS

Fourteen adults with ABI, evaluated over 6 months, and a reference sample of 30 healthy adults were studied. The primary measure for changes in mobility was the Clinical Outcome Variables Scale (COVS). Secondary measures were sit-to-stand, timed standing holding rails, independent walking speed and number of testing conditions achieved. The Functional Independence Measure (FIM) was scored at rehabilitation admission and discharge. To analyze postural alignment, participants were recorded in sitting and standing, each repeated holding rails, and walking if able. Three-dimensional kinematic data were used to quantify whole-body postural alignment, equal to mean segment displacements from the base of support in the transverse plane. Associations between three-dimensional kinematic alignment scores and COVS scores were calculated using Linear Mixed-Effects Models.

RESULTS

Participants made significant improvements in COVS scores, most secondary mobility scores, and FIM scores over time (p ≤ .001). Relationships between increasing COVS scores and decreasing sitting and standing mal-alignment scores were statistically significant. Visual analysis of graphed segment positions indicated that sitting and standing alignment became more similar to healthy alignment over time; this was not clear for walking.

CONCLUSION

Improvement in postural alignment may be a factor for improving mobility in people with severe impairments after ABI.

Improving physical mobility is critical for wellbeing in people with severe impairment after an acquired brain injury: a qualitative study

OBJECTIVES

1) Understand the experience, and personal significance, of mobility skills for people with severe mobility impairment after brain injury 2) Determine how these evolve over time.

DESIGN

Longitudinal qualitative study.

PARTICIPANTS

Ten adults, unable to walk at 8 weeks post-injury.

METHODS

Participants were interviewed up to three times, at three-month intervals. Semi-structured interviews were transcribed and coded independently by two researchers, then themes developed. Codes were then reviewed longitudinally.

RESULTS

Initial analysis derived six themes: I lost everything overnight; It feels frustrating; Walking is absolutely the most important; I need help; I'm making progress; I can start doing things that I used to be able to do. Participants described overwhelming losses, with loss of mobility affecting many aspects of life. All participants described progress other than walking that was critical for their wellbeing, including assisted standing and transfers without a lifter. Themes from longitudinal analyses: My losses softened by progress; Walking means freedom; Control helps adjustment happen; Challenges keep coming. Over time, participants valued greater control within their lives and progress with mobility was key.

CONCLUSION

Participants saw mobility as crucial to recovering control of life. Mobility achievements other than independent walking matter to individuals after brain injury.

Effect of Individual Nutrition Therapy and Exercise Regime on Gait Speed, Physical Function, Strength and Balance, Body Composition, Energy and Protein, in Injured, Vulnerable Elderly: A Multisite Randomized Controlled Trial (INTERACTIVE)

It is imperative that the surgical treatment of hip fractures is followed up with rehabilitation to enhance recovery and quality of life. This randomized controlled trial aimed to determine if an individualised, combined exercise–nutrition intervention significantly improved health outcomes in older adults, after proximal femoral fracture. We commenced the community extended therapy while in hospital, within two weeks post-surgery. The primary outcome was gait speed and secondary outcomes included physical function, strength and balance, body composition, energy and protein intake. Eighty-six and 89 participants were randomized into six months individualised exercise and nutrition intervention and attention-control groups, respectively. There were no statistically significant differences in gait speed between the groups at six and 12 months. There were no major differences between groups with respect to the secondary outcomes, except estimated energy and protein intake. This may be explained by the sample size achieved. Participants in the intervention group had greater increment in energy (235 kcal; 95% CI, 95 to 375; p = 0.01) and protein intake (9.1 g; 95% CI, 1.5 to 16.8; p = 0.02), compared with those in the control group at six months but not significant at 12 months. This study has demonstrated that providing early, combined exercise and nutrition therapy can improve dietary energy and protein intake in older adults with hip fractures.

Development of autonomy on placement: perceptions of physiotherapy students and educators in Australia and the United Kingdom

Objectives:This paper explores the decision-making processes involved in giving physiotherapy students responsibility on clinical placement and the impact on their developing professional autonomy. Methods: The qualitative study, using semi-structured interviews, involved physiotherapy students and clinical educators (CEs) from two higher education institutions, one in Australia, and the other in the United Kingdom (UK). Findings: Findings led to the development of a heuristic framework of 'graduated supervision,' a process of progressively less direct observation and monitoring of students as clinical proficiency improved. By focusing on the measured exposure of students to increasing complexity and inverse levels of supervision, the framework captures tacit practices, and consistent, yet varied facilitation strategies adopted across specialties, and evident in clinical education settings in both countries. The framework formalizes, for the first time, assumptions and expectations previously unacknowledged. Factors identified as affecting students' progress toward autonomy include the student/CE relationship, the development of mutual trust through ongoing dialogue, and the importance of formal discussions at the commencement of a clinical placement to establish learning goals, preferred supervision styles and learner responsibilities. Conclusion: Insights have significance for the CE community, and students who at times have to second-guess what is required of them and how they might excel on clinical placement.

Is the psychological composition of the therapeutic group associated with individual outcomes in group cognitive behavioural therapy for chronic pain?

This study explored whether the psychological composition of a group, with respect to mood, catastrophising, fear of movement and pain self-efficacy characteristics at baseline, is associated with individuals' treatment outcomes following group cognitive behavioural therapy (CBT)-based programmes for chronic pain. Retrospective analyses of outcomes from two independently run CBT-based pain management programmes (Programme A: N = 317 and Programme B: N = 693) were conducted. Mixed modelling analyses did not consistently support the presence of associations between group median scores of depression, catastrophising or fear avoidance with outcomes for individuals in either programme. These results suggest that the psychological profiles of groups are not robust predictors of individual outcomes in CBT groups for chronic pain. By implication, efforts made to consider group composition with respect to psychological attributes may be unnecessary.

Home-Based Occupational Therapy for Adults With Dementia and Their Informal Caregivers: A Systematic Review

IMPORTANCE

People with dementia require tailored interventions to support participation and performance in their desired occupations, and informal caregivers need interventions that reduce caregiving burden to enable them to continue with their roles.

OBJECTIVE

This systematic review investigated whether home-based occupational therapy interventions for adults with dementia and their informal caregivers optimized care recipients' performance of daily occupations and reduced caregiving burden and improved caregivers' sense of competence.

DATA SOURCES

Eight databases were searched from 1946 to November 2019 using MeSH terms, keywords, and subject headings as appropriate for each database. Inclusion criteria were quantitative studies investigating the effects of home-based therapy provided by a qualified occupational therapist for adults with dementia and their informal caregivers.

STUDY SELECTION AND DATA COLLECTION

Study selection, data collection, and methodological quality assessments using the Critical Appraisal Skills Programme criteria tool were performed independently by two reviewers. Data analysis involved a two-stage process.

FINDINGS

From 1,229 articles identified through searches, 970 titles and abstracts were screened for eligibility after removal of duplicates. Twenty studies reported in 22 articles were included. Moderate evidence supported interventions provided jointly for adults with dementia and their informal caregivers using a combination of intervention strategies. Included studies demonstrated high risk of bias, particularly in blinding of outcome assessments.

CONCLUSIONS AND RELEVANCE

Combining individualized interventions framed in client-centeredness can enhance occupational performance for adults with dementia, reduce caregiving burden, and improve informal caregivers' sense of competence. Further research on leisure and home management occupations is warranted.

WHAT THIS ARTICLE ADDS

The findings provide evidence supporting the effectiveness of home-based occupational therapy for people with dementia and their informal caregivers for consideration by funders of services.

Safe Exercise at Home Website: Keeping Older People Active during COVID-19

Background Physical distancing restrictions, including recommendations to ‘stay home’ during the COVID-19 pandemic has restricted exercise opportunities for older adults. Our group of academic and clinical physiotherapists and a communications expert identified the need to support safe exercise at home to minimise the impact of these restrictions. The project aimed to develop an online, publicly available resource to support older adults to exercise at home. We met virtually and: a) developed home exercise programs for people at three levels of functional ability; b) developed simple advice about exercising safely, exercise intensity, and staying motivated; and c) reviewed and selected online exercise programs and resources for consumers and health professionals to access. Examples of older adults keeping active during the pandemic were sourced to provide motivation. Website content was made available to download and print to increase accessibility. Modifications were made after consumer and international advisor feedback, the website was endorsed by the Australian Physiotherapy Association. Content is updated as restrictions are modified and in response to feedback received. Google Analytics was used to evaluate website usage. The website was launched on 5 May 2020, 35 days after the group’s initial meeting. In the first 9 weeks of website availability 20,608 users accessed the website, with 14.6% being returning users. There were 27,513 sessions and 74,927 page views. Most users were from Australia (80.74%), followed by Denmark (5.15%) and USA (3.85%) We present this example of the benefits of time-critical collaboration to facilitate rapid translation of evidence into practice.

Can student-peers teach using simulated-based learning as well as faculty: A non-equivalent posttest-only study

BACKGROUND

Peer-assisted learning has an important place in the delivery of health care education with benefits for both the learners and the peer teachers. Simulation-based learning (SBL) is evolving in healthcare professions training and academic programs as a modality that conveys realism and fidelity through immersion.

OBJECTIVES

The primary aim was to compare physiotherapy student's motivation to learn between a conventional faculty-led SBL activity and the same SBL activity delivered by trained final year physiotherapy peer tutors.

METHODS

Physiotherapy students from two Universities (n = 226) undertook a SBL learning activity (either faculty led or peer led) and completed the Instructional Materials Motivation Scale questionnaire to assess motivation to learn.

RESULTS

There was a high level of learner motivation in all learning groups, with significantly higher learner satisfaction (p < 0.001) and lower attention (p < 0.001) in student-led SBL than faculty-led SBL.

CONCLUSIONS

This study has highlighted the potential to incorporate peer-assisted and simulation-based learning together in the development of future educational activities in health care training.

Scope of occupational therapy practice for adults with both Down syndrome and dementia: A cross-sectional survey

INTRODUCTION

Dementia in adults with Down syndrome causes a progressive decline in daily occupations impacting both persons with Down syndrome and their informal caregivers. This study aimed to explore the scope of occupational therapy practice for adults with both Down syndrome and dementia and their informal caregivers living in their homes.

METHODS

A survey was conducted with occupational therapists having clinical experience in providing interventions for adults with Down syndrome. A web-based survey was developed to explore occupational therapy practice for this group of people with Down syndrome and their informal caregivers. Responses to closed-ended questions were analysed descriptively, and inductive content analysis was used for open-ended questions.

RESULTS

Forty-three occupational therapists from Australia, Canada, United Kingdom and the United States of America participated in the survey. Two-thirds were from the United Kingdom, most of whom were employed in the public sector and had at least 10 years of clinical experience. Over 90% of respondents received one or more referrals in a typical month for adults with Down syndrome having dementia, 68% of which were for a decline in activities of daily living. Home environment and activities of daily living were frequently assessed areas, and the commonest interventions were compensatory strategies and environmental modifications. Only half the respondents provided interventions for informal caregivers. Risk and safety and manual handling were frequently addressed domains for informal caregivers. Collaboration and developing clinical expertise were the two key perceived enablers for providing effective occupational therapy services. Fragmentation of services and a lack of client-centred care were the common perceived barriers.

CONCLUSION

Occupational therapists often address decline in activities of daily living for individuals with both Down syndrome and dementia. To support participation in meaningful occupations for these people and support the needs of their informal caregivers, it is essential that services are offered in a collaborative approach.

Paediatric flexible flat foot: how are we measuring it and are we getting it right? A systematic review

BACKGROUND

Flexible flat foot is a normal observation in typically developing children, however, some children with flat feet present with pain and impaired lower limb function. The challenge for health professionals is to identify when foot posture is outside of expected findings and may warrant intervention. Diagnoses of flexible flat foot is often based on radiographic or clinical measures, yet the validity and reliability of these measures for a paediatric population is not clearly understood. The aim of this systematic review was to investigate how paediatric foot posture is defined and measured within the literature, and if the psychometric properties of these measures support any given diagnoses.

METHODS

Electronic databases (MEDLINE, CINAHL, EMBASE, Cochrane, AMED, SportDiscus, PsycINFO, and Web of Science) were systematically searched in January 2017 for empirical studies where participants had diagnosed flexible flat foot and were aged 18 years or younger. Outcomes of interest were the foot posture measures and definitions used. Further articles were sought where cited in relation to the psychometric properties of the measures used.

RESULTS

Of the 1101 unique records identified by the searches, 27 studies met the inclusion criteria involving 20 foot posture measures and 40 definitions of paediatric flexible flat foot. A further 18 citations were sought in relation to the psychometric properties of these measures. Three measures were deemed valid and reliable, the FPI-6 > + 6 for children aged three to 15 years, a Staheli arch index of > 1.07 for children aged three to six and ≥ 1.28 for children six to nine, and a Chippaux-Smirak index of > 62.7% in three to seven year olds, > 59% in six to nine year olds and ≥ 40% for children aged nine to 16 years. No further measures were found to be valid for the paediatric population.

CONCLUSION

No universally accepted criteria for diagnosing paediatric flat foot was found within existing literature, and psychometric data for foot posture measures and definitions used was limited. The outcomes of this review indicate that the FPI - 6, Staheli arch index or Chippaux-Smirak index should be the preferred method of paediatric foot posture measurement in future research.

Is there a relationship between postural alignment and mobility for adults after acquired brain injury? A systematic review

PRIMARY OBJECTIVE

To examine the relationship between postural alignment and mobility skills for adults after acquired brain injury (ABI).

METHODS

Systematic review of the literature. Seven electronic databases, grey literature and reference lists of the shortlisted publications were searched. Studies were included if participants were adults with ABI, both postural alignment and mobility were measured and analysis included a relationship between alignment and mobility. Those that met the inclusion criteria were assessed with a critical appraisal tool. The review was registered with PROSPERO, registration number CRD42015019867.

RESULTS

Seven observational studies were included that had examined a relationship between postural alignment and mobility after ABI. Critical appraisal scores were moderate to strong. While some studies reported that improved postural alignment was related to improved mobility after ABI, results varied and there was insufficient evidence to answer the primary question. Heterogeneous study designs did not allow meta-regression.

CONCLUSIONS

A small amount of observational evidence exists for a relationship between postural alignment and mobility after ABI. Results vary, with some studies reporting that a more stable, upright trunk correlates with better mobility, and others providing conflicting or ambiguous results. Further research is needed to establish the relationship between postural alignment and mobility skills after ABI.

Harnessing group composition-related effects in pain management programs: a review and recommendations

Cognitive-behavioral therapy, an effective management strategy for chronic pain, is frequently conducted in groups. Although clinicians often report 'knowing when a group will go well or badly', investigations of the effect that group composition might have on outcomes is lacking. Conceptual models, explanatory theories and experiments have been developed in fields of psychotherapy, organizational, social and educational psychology, but there has been no attempt to take on this issue in our field. The current hypothesis-generating review synthesizes these substantial bodies of literature to identify common themes across fields and integrate them with current concepts of cognitive-behavioral therapy-based pain management. We present a putative conceptual model with testable hypotheses relating to features of each group as a whole, the individuals in that group and the group's leader.

Reconsidering inherent requirements: a contribution to the debate from the clinical placement experience of a physiotherapy student with vision impairment

BACKGROUND

Clinical placements in acute hospitals present challenges for students with vision impairment who are being educated as health care professionals. Legislation in Australia supports reasonable adjustments to education, thus students with vision impairment have completed accredited courses and gained professional registration. However the implementation of inherent requirement statements suggesting that adequate visual acuity is required to complete a physiotherapy program may create barriers to access for such students.

METHODS

We describe features that contributed to a successful physiotherapy clinical placement in an acute hospital setting for a student with vision impairment and use this experience to prompt debate about the use of inherent requirement statements.

FINDINGS

Planning, consultation, collaboration and problem solving commencing from the time of program entry were integral to clinical placement preparation for this student. Individualised adjustments (including a support worker for reading screens and medical records) and the student's specific qualities (professionalism, communication, problem solving, memory, kinaesthetic abilities) contributed to a successful outcome.

DISCUSSION

Reflecting on this experience and published inherent requirements, there is an apparent lack of involvement of people with disability in the development of inherent requirement statements; we question the need for this level of regulation; and discuss the potential impact of inherent requirement statements on the health workforce. This experience demonstrated that an individualised approach to reasonable adjustments for a student with a disability was successful in an acute hospital setting. The implementation of inherent requirement statements may systemically reduce the capacity of education providers to develop such bespoke solutions and deserves further debate.

Improvements in knee biomechanics during walking are associated with increased physical activity after total knee arthroplasty

Total knee arthroplasty (TKA) in people with knee osteoarthritis increases knee-specific and general physical function, but it has not been established if there is a relationship between changes in these elements of functional ability. This study investigated changes and relationships between knee biomechanics during walking, physical activity, and use of time after TKA. Fifteen people awaiting TKA underwent 3D gait analysis before and six months after surgery. Physical activity and use of time were determined in free-living conditions from a high resolution 24-h activity recall. After surgery, participants displayed significant improvements in sagittal plane knee biomechanics and improved their physical activity profiles, standing for 105 more minutes (p=0.001) and performing 64 min more inside chores on average per day (p=0.008). Changes in sagittal plane knee range of motion (ROM) and peak knee flexion positively correlated with changes in total daily energy expenditure, time spent undertaking moderate to vigorous physical activity, inside chores and passive transport (r=0.52-0.66, p=0.005-0.047). Restoration of knee function occurs in parallel and is associated with improvements in physical activity and use of time after TKA. Increased functional knee ROM is required to support improvements in total and context specific physical activity.

Adults with flexible pes planus and the approach to the prescription of customised foot orthoses in clinical practice: A clinical records audit

A clinical records audit of the University of South Australia's podiatry clinic clients attending in 2010 was undertaken to determine prevalence of symptomatic flexible pes planus, presenting reasons and treatment options most frequently used. Analysis of rearfoot measures (resting calcaneal stance position, subtalar joint range of motion) between those prescribed a vertical (heel) or inverted (heel) cast pour and a medial heel (Kirby) skive was undertaken. Of 223 clinical records audited, 50% (111/223) of clients were assessed with flexible pes planus, 77% (86/111) of clients with pes planus presented with back or lower limb pain and 58% (64/111) were prescribed customised foot orthoses. Of 42 prescriptions for customised foot orthoses audited; 64% (27/42) were prescribed a vertical (heel) cast pour, 36% (15/42) an inverted (heel) cast pour and 19% (8/42) received a medial heel (Kirby) skive. Those prescribed a medial heel (Kirby) skive had a more everted resting calcaneal stance position than those that were not (mean -8.6±2.8° vs. -5.5±3.4°, p=0.02). Those prescribed an inverted (heel) cast pour had a greater range of subtalar joint motion than those prescribed a vertical (heel) cast pour (median 36.0±10.0° vs. 29.0±5.0°, p=0.01).

Altered dynamic foot kinematics in people with medial knee osteoarthritis during walking: a cross-sectional study

BACKGROUND

Footwear and insoles are used to reduce knee load in people with medial knee osteoarthritis (OA), despite a limited understanding of foot function in this group. The aim of this study was to investigate the differences in foot kinematics between adults with and without medial knee OA during barefoot walking.

METHODS

Foot kinematics were measured during walking in 30 adults; 15 with medial knee OA (mean age was 67.0 with a standard deviation (SD) of 8.9 years; height was 1.66 with SD of 0.13 m; body mass was 84.2 with SD of 15.8 kg; BMI was 30.7 with SD of 6.2 kg/m(2); K-L grade 3: 5, grade 4: 10) and 15 aged and gender matched control participants with 12 motion analysis cameras using the IOR multi-segment foot model. Motion of the knee joint, hindfoot, midfoot, forefoot and hallux were compared between groups using clustered linear regression.

RESULTS

The knee OA group displayed reduced coronal plane range of motion of the midfoot (mean 3.8° vs. 5.4°, effect size=1.1, p=0.023), indicating reduced midfoot mobility. There was also a reduced sagittal plane range of motion at the hallux in the knee OA group compared to the control group (mean 29.6° vs. 36.3°, effect size=1.2, p=0.008). No statistically significant differences in hindfoot or forefoot motion were observed.

CONCLUSIONS

People with medial knee OA display altered foot function compared to healthy controls. As foot and knee function are related, it is possible that altered foot function in people with knee OA may influence the effects of footwear and insoles.

Consensus-based recommendations of Australian podiatrists for the prescription of foot orthoses for symptomatic flexible pes planus in adults

BACKGROUND

Foot orthoses are commonly used for symptomatic flexible pes planus in adults. However, there are no clinical guidelines for the prescription of customised foot orthoses that are specific to this population. The aim of this study was to investigate prescription habits of Australian podiatrists for customised foot orthoses for symptomatic flexible pes planus in adults and to develop consensus-based practice recommendations for the prescription of these foot orthoses.

METHODS

A four round Delphi survey was undertaken with 24 podiatric experts to establish current use and rationale for individual prescription variables of customised foot orthoses for symptomatic flexible pes planus in adults. Round one determined prescription use (consensus) and rounds two, three and four determined the rationale for use (agreement) of prescription variables across the rearfoot, midfoot, forefoot, as well as accommodation and materials used. For consensus and agreement to be accepted, 70% of the respondents were required to use or agree on the rationale for use of individual prescription variables.

RESULTS

Consensus was reached in round one for two variables, choice of shell material (polyolefin) and when to prescribe a forefoot post balanced to perpendicular. In rounds two, three and four, agreement was reached for 52 statements related to the rationale for use of individual prescription variables, including when to prescribe: an inverted cast pour [heel in an inverted position], an inverted rearfoot post, a medial heel (Kirby) skive, minimal/maximum arch fill, a medial flange, a forefoot post and common orthotic accommodations.

CONCLUSION

This study found consensus or agreement for the use of several prescription variables for customised foot orthoses for symptomatic flexible pes planus in adults. The findings were used to develop the Foot orthosis Prescription Recommendations for symptOmatic flexible Pes planus in adults (FootPROP) proforma, to guide clinicians and researchers in the prescription of customised foot orthoses for this population.

Foot orthoses for adults with flexible pes planus: a systematic review

BACKGROUND

Foot orthoses are widely used in the management of flexible pes planus, yet the evidence to support this intervention has not been clearly defined. This systematic review aimed to critically appraise the evidence for the use of foot orthoses for flexible pes planus in adults.

METHODS

Electronic databases (Medline, CINAHL, Cochrane, Web of science, SportDiscus, Embase) were systematically searched in June 2013 for randomised controlled, controlled clinical and repeated measure trials where participants had identified flexible pes planus using a validated and reliable measure of pes planus and the intervention was a rigid or semi-rigid orthoses with the comparison being a no-orthoses (shoes alone or flat non-posted insert) condition. Outcomes of interest were foot pain, rearfoot kinematics, foot kinetics and physical function.

RESULTS

Of the 2,211 articles identified by the searches, 13 studies met the inclusion criteria; two were randomised controlled trials, one was a controlled trial and 10 were repeated measure studies. Across the included studies, 59 relevant outcome measures were reported with 17 calculated as statistically significant large or medium effects observed with use of foot orthoses compared to the no orthoses condition (SMD range 1.13 to -4.11).

CONCLUSIONS

No high level evidence supported the use of foot orthoses for flexible pes planus. There is good to moderate level evidence that foot orthoses improve physical function (medial-lateral sway in standing (level II) and energy cost during walking (level III)). There is low level evidence (level IV) that foot orthoses improve pain, reduce rearfoot eversion, alter loading and impact forces; and reduce rearfoot inversion and eversion moments in flexible pes planus. Well-designed randomised controlled trials that include appropriate sample sizes, clinical cohorts and involve a measure of symptom change are required to determine the efficacy of foot orthoses to manage adult flexible pes planus.

Differences in foot kinematics between young and older adults during walking

Our understanding of age-related changes to foot function during walking has mainly been based on plantar pressure measurements, with little information on differences in foot kinematics between young and older adults. The purpose of this study was to investigate the differences in foot kinematics between young and older adults during walking using a multi-segment foot model. Joint kinematics of the foot and ankle for 20 young (mean age 23.2 years, standard deviation (SD) 3.0) and 20 older adults (mean age 73.2 years, SD 5.1) were quantified during walking with a 12 camera Vicon motion analysis system using a five segment kinematic model. Differences in kinematics were compared between older adults and young adults (preferred and slow walking speeds) using Student's t-tests or if indicated, Mann-Whitney U tests. Effect sizes (Cohen's d) for the differences were also computed. The older adults had a less plantarflexed calcaneus at toe-off (-9.6° vs. -16.1°, d = 1.0, p = <0.001), a smaller sagittal plane range of motion (ROM) of the midfoot (11.9° vs. 14.8°, d = 1.3, p = <0.001) and smaller coronal plane ROM of the metatarsus (3.2° vs. 4.3°, d = 1.1, p = 0.006) compared to the young adults. Walking speed did not influence these differences, as they remained present when groups walked at comparable speeds. The findings of this study indicate that independent of walking speed, older adults exhibit significant differences in foot kinematics compared to younger adults, characterised by less propulsion and reduced mobility of multiple foot segments.

Repeatability of stance phase kinematics from a multi-segment foot model in people aged 50 years and older

Confidence in 3D multi-segment foot models has been limited by a lack of repeatability data, particularly in older populations that may display unique functional foot characteristics. This study aimed to determine the intra and inter-observer repeatability of stance phase kinematic data from a multi-segment foot model described by Leardini et al. [2] in people aged 50 years or older. Twenty healthy adults participated (mean age 65.4 years SD 8.4). A repeated measures study design was used with data collected from four testing sessions on two days from two observers. Intra (within-day and between-day) and inter-observer coefficient of multiple correlations revealed moderate to excellent similarity of stance phase joint range of motion (0.621-0.975). Relative to the joint range of motion (ROM), mean differences (MD) between sessions were highest for the within-day comparison for all planar ROM at the metatarsus-midfoot articulation (sagittal plane ROM 5.2° vs. 3.9°, MD 3.1°; coronal plane ROM 3.9 vs. 3.1°, MD 2.3°; transverse plane ROM 6.8° vs. 5.16°, MD 3.5°). Consequently, data from the metatarsus-midfoot articulation in the Istituto Ortopedico Rizzoli (IOR) foot model in adults aged over 50 years needs to be considered with respect to the findings of this study.

The journey to total hip or knee replacement

OBJECTIVES

Despite the incidence of joint replacements in Australia, there is a paucity of information regarding how patients progress from their referral to their surgery. The aim of this study was to describe a patient pathway from referral to receipt of total hip replacement (THR) or total knee replacement (TKR) surgery in South Australian public hospitals.

METHODS

Patient perspectives of the pathway to THR and TKR surgery were obtained via a postal survey (n=450) and hospital employee perspectives were attained via semi-structured interviews (n=19). Survey data were analysed using descriptive statistics and interview data were analysed thematically.

RESULTS

A typical patient pathway to THR and TKR surgery can be divided into two distinct phases; referral-to-initial appointment (9-24 months), and initial appointment-to-surgery (12-15 months). This gives an overall waiting period between 2 and 3 years for THR or TKR surgery.

CONCLUSIONS

Waiting times for THR and TKR surgery reported in this study were longer than other reports in the literature. Current Australian health policy does not consider the first (and longest) phase of the patient pathway. Excluding this initial phase could be generating an erroneous perception of the patient pathway to THR or TKR surgery, possibly leading to poorly considered health reforms.

Sociodemographic factors associated with self-reported exercise and physical activity behaviors and attitudes of South Australians: results of a population-based survey

OBJECTIVE

To determine self-reported physical activity barriers, behaviors, and beliefs about exercise of a representative sample and to identify associated sociodemographic factors.

METHOD

Face-to-face interviews conducted between September and December 2008, using a random stratified sampling technique.

RESULTS

Barriers injury and illness were associated with being older, single, and not engaged in full-time work; lack of time was associated with being married, younger, female, and working full-time; and lack of motivation and cost were associated with being younger than 65 years. Advancing age was significantly associated (p < .001) with reduced physical activity. Factors including age, education, marital status, and area of residence were all associated with preferences for environment to exercise in, while all age groups (74%) felt that walking was the most important type of exercise for older adults.

DISCUSSION

A better understanding of these factors may improve uptake of and adherence to exercise programs across the ages.

Walking aid use after discharge following hip fracture is rarely reviewed and often inappropriate: an observational study

QUESTIONS

What walking aid prescription occurs at discharge after hip fracture? What changes in walking aid use occur in the following six months? Who initiates changes in walking aids and why?

DESIGN

Prospective longitudinal observational study.

PARTICIPANTS

95 community-dwelling older adults who had undergone surgical treatment of a hip fracture.

OUTCOME MEASURES

Range of walking aids prescribed at discharge and participants' recall of advice about progression were recorded. Progression of walking aids was observed fortnightly over 6 months. With any change in walking aid use, an independent physiotherapist determined if it was appropriate and participants reported the reason for the change.

RESULTS

Most participants were discharged from their final inpatient setting with a wheeled frame (92%). Eighty-two (86%) participants were not aware of any goals set by the physiotherapist for the first 6 months and 89 (94%) stated that a review time had not been set. Despite this, 78 (82%) participants changed their walking aid, on average 8 weeks (SD 6) after discharge. However, 32% of those who changed their walking aids were using an inappropriate aid or using it incorrectly. Six months after discharge, 40% of participants had not returned to using their pre-morbid indoor aid and 50% their outdoor aid.

CONCLUSION

A review of walking aid by a physiotherapist is rare within six months after discharge following hip fracture. Most patients make their own decision about what walking aid is most appropriate. This has safety implications in a group at high risk of falls.

Does the 'Otago exercise programme' reduce mortality and falls in older adults?: a systematic review and meta-analysis

BACKGROUND

the 'Otago exercise programme' (OEP) is a strength and balance retraining programme designed to prevent falls in older people living in the community. The aim of this review was to evaluate the effect of the OEP on the risk of death and fall rates and to explore levels of compliance with the OEP in older adults.

METHODS

a systematic review with meta-analysis. Clinical trials where the OEP was the primary intervention and participants were community-dwelling older adults (65+) were included. Outcomes of interest included risk of death, number of falls, number of injurious falls and compliance to the exercise programme.

RESULTS

seven trials, involving 1503 participants were included. The mean age of participants was 81.6 (±3.9) years. The OEP significantly reduced the risk of death over 12 months [risk ratio = 0.45, 95% confidence interval (CI) = 0.25-0.80], and significantly reduced fall rates (incidence rate ratio = 0.68, 95% CI = 0.56-0.79). There was no significant difference in the risk of a serious or moderate injury occurring as the result of a fall (risk ratio = 1.05, 95% CI = 0.91-1.22). Of the 747 participants who remained in the studies at 12 months, 274 (36.7%) were still exercising three or more times per week.

CONCLUSION

the OEP significantly reduces the risk of death and falling in older community-dwelling adults.

What works in falls prevention after stroke?: a systematic review and meta-analysis

BACKGROUND AND PURPOSE

Falls are common after stroke. Despite evidence that single and multifactorial interventions can reduce falls in older people, this issue remains relatively underexplored in stroke survivors. Effective fall prevention in this population has the potential to prevent injury, improve quality of life, and decrease the likelihood of subsequent fear of falling and activity restriction. The aim of this article was to review and integrate the research evidence relating to interventions that reduce falls after stroke.

METHODS

Published studies evaluating interventions to reduce falls in stroke survivors were retrieved and screened according to predetermined criteria. Included studies were independently assessed. Quality of trials was assessed using the Physiotherapy Evidence Database score. Pooling of results was undertaken for similar interventions with comparable outcomes using the inverse variance method.

RESULTS

Thirteen studies met the inclusion criteria, with pooling of results possible for only 2 types of intervention. Methodological quality of the included studies was variable with the main bias because of lack of blinding of participants and those administering the intervention. Variability in falls data reporting was seen across the studies. The only intervention shown to be effective in reducing falls was vitamin D for female stroke survivors in an institutional setting. Other interventions were no more effective than usual care.

CONCLUSIONS

Fall risk is high in stroke survivors; however, the only intervention shown to be effective in reducing falls in this review was vitamin D supplementation. Consistency in outcome measurement would enable comparisons across studies. Additionally, further research evaluating a range of single and multifactorial interventions for fall prevention in the stroke population is required.

Acupuncturists' perspectives on outcome measures to evaluate acupuncture care for chronic low back pain

OBJECTIVES

To examine Australian acupuncturists' perspectives of: chronic low back pain outcome domains; their use of outcome measures to assess chronic low back pain; and their attitudes and perceptions of barriers to using the existing measures to evaluate acupuncture care for chronic low back pain.

DESIGN

A postal questionnaire was used in a cross-sectional survey.

PARTICIPANTS

359 randomly selected Australian acupuncturists.

RESULTS

139 questionnaires were returned (response rate: 38.7%). The respondents' demographic characteristics were similar to Australian Bureau of Statistics acupuncturist demographic data. Overall, acupuncturists endorsed a broad approach to assessing acupuncture care for chronic low back pain. However, they had typically used pain severity measures but generally did not use other types of measures. Acupuncturists tended to hold positive attitudes towards using outcome measures. The principal barriers acupuncturists perceived to using outcome measures concerned doubts about whether the concepts which underpin acupuncture practice had been explicitly articulated and whether the available measures capture the specific context and particular outcomes of acupuncture care for chronic low back pain.

IMPLICATIONS

The findings of this study suggest that a broad range of outcome measures are required to adequately assess chronic low back pain acupuncture care outcomes. While numerous outcome measures have been developed that are relevant to chronic low back pain care, whether these measures are appropriate for use by acupuncturists is unclear. Further studies are warranted to explore if established outcome measures are useful to evaluate chronic low back acupuncture care.

Individual nutrition therapy and exercise regime: a controlled trial of injured, vulnerable elderly (INTERACTIVE trial)

Background

Proximal femoral fractures are amongst the most devastating consequences of osteoporosis and injurious accidental falls with 25–35% of patients dying in the first year post-fracture. Effective rehabilitation strategies are evolving however, despite established associations between nutrition, mobility, strength and strength-related functional outcomes; there has been only one small study with older adults immediately following fragility fracture where a combination of both exercise and nutrition have been provided. The aim of the INTERACTIVE trial is to establish whether a six month, individualised exercise and nutrition program commencing within fourteen days of surgery for proximal femur fracture, results in clinically and statistically significant improvements in physical function, body composition and quality of life at an acceptable level of cost and resource use and without increasing the burden of caregivers.

Methods and Design

This randomised controlled trial will be performed across two sites, a 500 bed acute hospital in Adelaide, South Australia and a 250 bed acute hospital in Sydney, New South Wales. Four hundred and sixty community-dwelling older adults aged > 70 will be recruited after suffering a proximal femoral fracture and followed into the community over a 12-month period. Participants allocated to the intervention group will receive a six month individualised care plan combining resistance training and nutrition therapy commencing within 14 days post-surgery. Outcomes will be assessed by an individual masked to treatment allocation at six and 12 months. To determine differences between the groups at the primary end-point (six months), ANCOVA or logistic regression will be used with models adjusted according to potential confounders.

Discussion

The INTERACTIVE trial is among the first to combine nutrition and exercise therapy as an early intervention to address the serious consequence of rapid deconditioning and weight loss and subsequent ability to regain pre-morbid function in older patients post proximal femoral fracture. The results of this trial will guide the development of more effective rehabilitation programs, which may ultimately lead to reduced health care costs, and improvements in mobility, independence and quality of life for proximal femoral fracture sufferers.
