Does an alternative breast support garment provide symptomatic relief for larger breasted women with chronic non-specific back pain?

BACKGROUND: Nonsurgical guidelines recommend implementing a correctly fitted bra when managing back pain among larger breasted women. Achieving this is challenging with current bra solutions, sizing principles, and fitting approaches. Persistent wearing of an ill-fitting bra can cause negative health implications, including non-specific back pain. OBJECTIVES: This study investigated immediate and short-term biomechanical and pain responses to changing breast support garment among larger breasted women with non-specific back pain. METHODS: Participants (n = 24) performed a standing task, drop jumps, and seated typing tasks while bra and spinal kinematic data were recorded. Five breast support conditions were assessed: participants' usual bra (control), a professionally fitted bra in the immediate term (standard) and after 4 weeks wear (standard28), and a bra with an alternative design, measurement, and fitting approach in both the immediate term (alternative) and after 4 weeks wear (alternative28). A bra fit assessment and clinical pain/disability questionnaires were included. RESULTS: All participants failed the bra fit assessment in the control bra, compared with 87.5% (n = 21) in the standard and 4.2% (n = 1) in the alternative bras. The standard28 and alternative28 bras provided symptomatic relief, with the alternative28 bra improving a greater number of outcome measures. Reduced nipple-sternal-notch distance was observed only in the alternative28 bra condition. CONCLUSIONS: Symptomatic relief may be associated with the resting position of the breast tissue on the anterior chest wall. The alternative bra may provide potential clinical benefit if implemented as part of a nonsurgical or conservative pain management strategy. Alternative breast support garments should be considered to provide solutions to the problems associated with traditional bras.

The Ability of Austrian Qualified Physiotherapists to Make Accurate Keep-Refer Decisions and to Detect Serious Pathologies Based on Clinical Vignettes: Protocol for a Cross-sectional Web-Based Survey.

BACKGROUND: The recognition of serious pathologies affecting the musculoskeletal (MSK) system, especially in the early stage of a disease, is an important but challenging task. The prevalence of such serious pathologies is currently low. However, in our progressing aging population, it is anticipated that serious pathologies affecting the MSK system will be on the rise. Physiotherapists, as part of a wider health care team, can play a valuable role in the recognition of serious pathologies. It is at present unknown how accurately Austrian qualified physiotherapists can detect the presence of serious pathologies affecting the MSK system and therefore determine whether physiotherapy management is indicated (keep patients) or not (refer patients to a medical doctor). OBJECTIVE: We will explore the current ability of Austrian qualified physiotherapists to recognize serious pathologies by using validated clinical vignettes. METHODS: As part of an electronic web-based survey, these vignettes will be distributed among a convenience sample of qualified Austrian physiotherapists working in a hospital or private setting. The survey will consist of four sections: (1) demographics and general information, (2) the clinical vignettes, (3) questions concerning the clinical vignettes, and (4) self-perceived knowledge gaps and learning preferences from the perspective of study participants. Results will further be used for (1) international comparison with similar studies from the existing literature and (2) gaining insight into the participants' self-perceived knowledge gaps and learning preferences for increasing their knowledge level about keep-refer decision-making and detecting serious pathologies. RESULTS: Data collection took place between May 2022 and June 2022. As of June 2022, a total of 479 Austrian physiotherapists completed the survey. Data analysis has started, and we aim to publish the results in 2023. CONCLUSIONS: The results of this survey will provide insights into the ability of Austrian physiotherapists to make accurate keep-refer decisions and to recognize the presence of serious pathologies using clinical vignettes. The results of this survey are expected to serve as a basis for future training in this area. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/43028.

Reablement - relevant factors for implementation: an exploratory sequential mixed-methods study design.

BACKGROUND: Reablement is a multi-professional and internationally established home-based health care service for mainly older people with the aim to reduce the need for long-term care and to promote self-determination. However, it is unknown which factors would facilitate the implementation of reablement in health care services. Therefore, the aim of this work was to identify relevant factors for the implementation process and to elucidate their importance based on the perspectives of experts. METHODS: Within an exploratory sequential mixed-methods design, a literature search followed by framework analysis was carried out using the five domains of the Consolidated Framework of Implementation Research (CFIR) to collect potentially relevant factors for implementation of reablement. A survey was then drawn up encompassing the factors identified. Within the survey international reablement - experts were asked to rate the relevance of these factors . RESULTS: The literature search identified 58 publications that served as sources for the framework analysis, where 40 potentially relevant factors were clustered into the five CFIR domains. These 40 factors were rated by experts in an online-survey. Based on the analysis of survey-data, 35 factors were considered as relevant for implementation of reablement services. The CFIR-domain characteristics of individuals, including teamwork and communication skills, was seen as most relevant. CONCLUSIONS: The implementation of reablement services is complex and requires the consideration of numerous factors, especially regarding the CFIR-domain characteristics of individuals. From the perspective of the survey´s participants one important factor of a successful implementation was the engagement of the persons involved. It requires team members with a strong, shared vision. Communication skills are highly important to promote teamwork and intensive training is needed to establish these skills. Further research on the implementation of reablement services is essential to realize its full potential.

The Efficacy of a Newly Developed Cueing Device for Gait Mobility in Parkinson's Disease.

Background: External cues are effective in improving gait in people with Parkinson's disease (PD). However, the most effective cueing method has yet to be determined. Objective: The aim of this study was to compare the immediate effects of using visual, auditory, or somatosensory cues on their own or in combination during walking compared to no cues in people with PD. Methods: This was a single blinded, randomly selected, controlled study. Twenty people with PD with an age range of 46-79 years and Hoehn and Yahr scores of 1-3 were recruited. Participants were studied under 4 cueing conditions; no cue, visual, auditory, or somatosensory cues, which were randomly selected individually or in a combination. Results: A repeated measures ANOVA with pairwise comparisons using Bonferroni correction showed that any single or combination of the cues resulted in an improvement in gait velocity and stride length compared to no cue. Some significant differences were also seen when comparing different combinations of cues, specifically stride length showed significant improvements when additional cues were added to the light cue. The statistically significant difference was set at p < 0.05. Conclusions: Walking using visual, auditory, or somatosensory cues can immediately improve gait mobility in people with PD. Any or a combination of the cues tested could be chosen depending on the ability of the individual to use that cue.

The impact of breast support garments on fit, support and posture of larger breasted women.

Due to current measurement, sizing and fitting approaches, poor bra fit is prevalent amongst larger breasted women. The impact of improving bra fit hasn't yet been explored. This pre-clinical study aimed to explore immediate and short-term biomechanical responses to changing breast support garment. Asymptomatic participants (n=24) performed a static standing task, drop jumps and seated typing whilst kinematic data from the breasts and spine were recorded. Three breast support conditions were assessed: Usual, professionally fitted bra in the immediate term (PFB), and the same professionally fitted bra after four weeks wear (PFB28). Bra fit assessments were included for both bras. All participants failed the bra fit assessment when wearing the Usual bra and 67% (n=16) failed when wearing the PFB. Less bra fit issues were present in the PFB, resulting in immediate biomechanical changes relating to breast support and spinal posture, yet nothing in the short term (PFB28). This research sets the foundations for future work to investigate whether the implementation of better fitting breast support garments can influence musculoskeletal pain amongst larger breasted women, whilst attributing potential improvement of symptoms, objective measures of breast support and spinal posture.

"I'm walking into the unknown": Qualitative insights into how emotions and lived experience related to multiple sclerosis diagnosis impact on decisions to pursue disease modifying treatment.

INTRODUCTION: People with Relapsing Remitting Multiple Sclerosis (RRMS) are increasingly included as active participants in shared decision making around their treatment options. Choosing a first disease modifying treatment (DMT) is a complex process that often takes place soon after a diagnosis has been given. Patients therefore are often required to make difficult decisions at a time when they are still coming to terms with their illness. This study investigated the views and experiences of recently diagnosed patients with RRMS when they were making their initial DMT choice. METHOD: This was a qualitative study involving in-depth semi-structured interviews with patients with RRMS in a National Health Service (NHS) setting in the United Kingdom. Data were collected from 6 patients and analysis was guided by an Interpretive Phenomenological Analysis (IPA) approach. RESULTS: Initial reactions to diagnosis were characterized by strong emotions and a feeling of despair and hopelessness. Subsequently the DMT decision was shaped by multiple considerations around maintaining normality, and restoring hope and control over one's life whilst reconciling uncertainty around efficacy. Considering the future with a DMT elicited reflections around employment and family planning. CONCLUSION: Emotions and lived experience related to recent MS diagnosis can impact on the initial DMT decision in number of ways. Health care professionals need to understand the lived experience of patients making DMT decisions soon after diagnosis when engaging in shared decision making.

Exploring a New Cueing Device in People Who Experience Freezing of Gait: Acceptance of a Study Design.

Background: Freezing of Gait (FoG) is a disabling symptom of Parkinson's Disease (PD) and is defined as a "brief episodic absence or marked reduction of forward progression of the feet despite the intention to walk." Compensatory strategies such as cueing and high frequency vibrotactile stimulation can reduce FoG severity and improve gait parameters. A new Sternal high frequency Vibrotactile Stimulation Device (SVSD) with cueing function has been developed, however the clinical effects of this device are yet to be fully investigated. Objective: The aim of this study was to investigate, if the proposed study design using a SVSD and gait analysis sensor insoles was acceptable for people with PD. Methods: This feasibility study was designed as a randomized cross-over study. Thirteen participants took part in a one off 60-minute data collection session. The acceptability of the study design was assessed with a mixed methods questionnaire considering each step of the study process. Secondary outcome measures were the feasibility of using the 10 Metre Walk Test (10MWT), the Freezing of Gait Score (FoG-Score), and Patient Global Impression of Change (PGI-C) with and without the SVSD. Results: The participants scored all aspects of the study design as very satisfactory. In addition, all participants could perform the secondary outcome measures and were deemed feasible. Feedback from open ended questions provided ideas and considerations for adaptations of future clinical studies. Conclusion: The proposed study design was acceptable for people with PD. Implications. This study design, with small adaptations, can be used for larger studies to evaluate the effect of an SVSD on FoG in people with PD.

Exploring the factors influencing the use of electrically assisted bikes (e-bikes) by stroke survivors: a mixed methods multiple case study.

PURPOSE: E-bikes have the potential to overcome some of the barriers that stroke survivors face with regards to physical activity. This study aims to explore the factors that affect e-bike usage by stroke survivors. METHODS: A mixed methods multiple case studies design, using semi-structured interviews and GPS data. Subject to GP approval, participants loaned an e-bike or e-trike for up to three months. Interviews were undertaken pre and post intervention. The COM-B behaviour change model acted as a framework for analysis. GPS data relating to journey duration and distance travelled was collected fortnightly. RESULTS: Six participants were recruited; only three loaned an e-bike/e-trike (with adaptations as required). Storage, being unable to get GP approval, and safety were withdrawal reasons. Level of impairment was a factor influencing the type of e-bike used, level of support required and the motivation of the participants. CONCLUSION: Stroke survivors can use e-bikes although barriers exist. Electrical assistance was a positive factor in enabling some of the participants to cycle outdoors. Due to the small sample size and the number of participants who were able to loan an e-bike, further research is required to determine whether e-bikes are a feasible and effective intervention to increase physical activity for stroke survivors.IMPLICATIONS FOR REHABILITATIONThe assistance provided by the e-bike/e-trike could provide stroke survivors the opportunity to cycle outdoors.E-bikes/e-trikes could facilitate participation of activities of everyday living such as shopping, hobbies and increase levels of physical activity.Rehabilitation could focus on physical impairment, its effects on self-confidence, and knowledge surrounding the e-bike to overcome barriers to cycling.Social support, the belief that e-bike was an enjoyable mode of physical activity that was good for their health were reported by the participants as important factors for using the e-bike/e-trike.

Response of salivary biomarkers to an empathy triggering film sequence-a pilot study.

Empathy is a multifaceted phenomenon that is difficult to measure. Self-report questionnaires are the most common and well-validated measures while currently no validated protein biomarkers associated with the empathic reaction have been established. Trigger films have been previously used in psychological research to evoke emotions. Thus, in the present randomized cross-over study we investigated the responses of nine salivary biomarkers that have been related to emotions and stress following an empathy triggering and a control film sequence. Additionally, questionnaires for empathy (Saarbrucken Personality Questionnaire (SPQ)) and current mental stress were applied and participants were asked to assess the film protagonists' emotions using the Positive and Negative Affect Schedule. Data from 46 participants were included in the analysis. α-Amylase, IgA, IL-1ß and estradiol showed a significantly different response between the empathy and control intervention. Moreover, normalized levels of these biomarkers significantly correlated with single scales of the SPQ (control film sequence: α-amylase and IgA with personal distress; estradiol with empathic concern; IL-1ß with fantasy; empathy triggering film sequence: IgA with empathic concern, fantasy and the total empathy score). These findings indicated that the observed changes in salivary biomarker levels were reflective of a physiological response to the empathy triggering film sequence. Future studies using different triggers and settings will show if the identified biomarkers can be considered as surrogate markers for empathic reactions in general.

An exploration of normative values in New Zealand to inform the Targeted Interventions for Patellofemoral Pain approach.

BACKGROUND: The Targeted Interventions for Patellofemoral Pain studies (TIPPs) have identified three subgroups exist in United Kingdom and Turkish patellofemoral pain (PFP) populations: Strong; Weak and Tight; and Weak and Pronated, based on six clinical assessments. The thresholds used to develop the subgrouping algorithms were based on normative values sourced from various populations and countries. OBJECTIVES: Explore normative scores from the clinical assessments in a singular non-PFP population whilst considering potential differences between ethnicities and sex (primary aim). Revisit inter-rater reliability of each assessment (secondary aim). DESIGN: Cross-sectional and test-retest. METHOD: The six assessments; rectus femoris length, gastrocnemius length, patellar mobility, hip abductor strength, quadriceps strength, and Foot Posture index (FPI) were measured in 89 New Zealanders (34% Maori, 45% female). Two raters independently assessed 17 participants to examine inter-rater reliability. RESULTS: Significant interactions between ethnic group and sex were noted for rectus femoris length and patella mobility. Maori versus European males exhibited greater rectus femoris tightness (p = 0.001). Maori versus European females demonstrated greater patellar mobility (p = 0.002). Females were significantly weaker than males in normalised strength measures (p < 0.001), and had lower FPIs. Mean differences between testers for all measures were small and not significant, except for FPI which had a 2.0 point median difference (p = 0.021). CONCLUSIONS: Our results indicate that sex is an important factor worth considering within the TIPPs subgrouping approach, more than ethnicity, especially for the normalised strength measures. The sub-optimal reliability of FPI warrant reconsideration of its inclusion within TIPPs.

Hot and cold knees: exploring differences in patella skin temperature in patients with patellofemoral pain.

OBJECTIVES: To investigate the distribution of patella skin temperature (Tsk) measurements and to explore the presence of temperature subgroups in patellofemoral pain (PFP) patients. DESIGN: Cross-sectional observational study design. PARTICIPANTS: One dataset of 58 healthy participants and 232 PFP patients from three different datasets. MAIN OUTCOME MEASURES: Patella skin temperature, measured by physiotherapists using a low cost hand held digital thermometer. The distribution of patella skin temperature was assessed and compared across datasets. To objectively determine the clinically meaningful number of subgroups, we used the average silhouette method. Finite mixture models were then used to examine the presence of PFP temperature subgroups. Receiver operating characteristic curves were used to estimate optimal patella Tsk thresholds for allocation of participants into the identified subgroups. RESULTS: In contrast to healthy participants, the patella skin temperature had an obvious bimodal distribution with wide dispersion present across all three PFP datasets. The fitted finite mixture model suggested three temperature subgroups (cold, normal and hot) that had been recommended by the average silhouette method with discrimination cut-off thresholds for subgroup membership based on receiver operating curve analysis of Cold=<30.0°C; Normal 30.0-35.2°C; Hot ≥35.2°C. CONCLUSION: A low cost hand held digital thermometer appears to be a useful clinical tool to identify three PFP temperature subgroups. Further research is recommended to deepen understanding of these clinical findings and to explore the implications to different treatments.

Factors Influencing the Delivery of Intensive Rehabilitation in Stroke: Patient Perceptions Versus Rehabilitation Therapist Perceptions.

BACKGROUND: Despite increasing evidence regarding the benefit of intensive task-specific practice and aerobic exercise in stroke rehabilitation, implementation remains difficult. The factors influencing implementation have been explored from therapists' perspectives; however, despite an increased emphasis on patient involvement in research, patients' perceptions have not yet been investigated. OBJECTIVE: The study aimed to investigate factors influencing implementation of higher intensity activity in people with stroke and to compare this with therapists' perspectives. DESIGN: The design was a cross-sectional qualitative study. METHODS: The study used semistructured interviews with people with stroke who were part of a randomized clinical trial, the Determining Optimal post-Stroke Exercise study, which delivered a higher intensity intervention. An interview guide was developed and data analyzed using implementation frameworks. Factors emerging from interviews with people with stroke were compared and contrasted with factors perceived by rehabilitation therapists. RESULTS: Ten people with stroke were interviewed before data saturation was reached. Participants had a positive attitude regarding working hard and were satisfied with the graded exercise test, high intensity intervention, and the feedback-monitoring devices. Therapists and patients had contrasting perceptions about their beliefs regarding intensive exercise and the content of the intervention, with therapists more focused on the methods and patients more focused on the personal interactions stemming from the therapeutic relationship. CONCLUSIONS: People with stroke perceived no barriers regarding the implementation of higher intensity rehabilitation in practice and were positive towards working at more intense levels. Contrastingly, from the therapists' perspective, therapists' beliefs about quality of movement and issues around staffing and resources were perceived to be barriers. In addition, therapists and people with stroke perceived the contents of the intervention differently, highlighting the importance of involving patients and clinicians in the development and evaluation of rehabilitation interventions.

Inequalities in access to health and social care among adults with multiple sclerosis: A scoping review of the literature.

Variations in access to health care are known to contribute to differences in life expectancy, morbidity and health-related quality-of-life across population subgroups. We undertook a scoping review to identify what is known about in-country variations in access to services for adults with multiple sclerosis and to identify gaps in the literature to inform future research and national policies. We searched MEDLINE, CINAHL, EMBASE, PSYCHINFO, SocINDEX and Social Science Abstracts from inception to end of December 2016 for quantitative studies which had investigated differences in access to prevention services, healthcare services, treatments and social care between inequality groups, defined using the PROGRESS-PLUS framework. A total of 4959 unique abstracts yielded 36 papers which met our eligibility criteria. Only 3 studies were cohort studies and only 4 were population-based; most were from the United States (n = 27). There were 6 studies on access to MS focused care and 6 on access to Disease Modifying drugs. There were 3 studies on access to prevention/lifestyle programmes and none on access to welfare services or information support. There were no papers examining inequalities in access for 'vulnerable' groups, such as, those with learning disability. In the available studies, there was evidence of inequalities in access to services with a trend for worse access among men, older age groups, those from lower socio-economic groups or the least educated, non-caucasians, those with mental health problems and those from rural areas. In the studies on access to disease modifying treatments, older age and lower socioeconomic status were consistently associated with a lower rate of uptake, while race and gender were not. Inequalities or disparities in access to all levels of services and treatments will need to be addressed through a strategic research agenda with an emphasis on population-based studies and development and evaluation of interventions to reduce inequality.

Effects of a 4-week intervention using semi-custom insoles on perceived pain and patellofemoral loading in targeted subgroups of recreational runners with patellofemoral pain.

OBJECTIVE: Explore the effects of a 4-week intervention using semi-custom insoles in recreational runners with patellofemoral pain. DESIGN: Mixed methods. PARTICIPANTS: Seventeen (10 males and 7 females) recreational runners. SETTING: Laboratory. OUTCOME MEASUREMENTS: Participants were separated into specific subgroups, then provided with a pair of semi-custom insoles, for a period of 4-weeks. Lower extremity kinetics/kinematics during running at 4.0 m/s were obtained. In addition, knee pain was examined using the Knee injury and Osteoarthritis Outcome Score-Patellofemoral scale (KOOS-PF). Data were collected before and after wearing the insoles for 4-weeks. RESULTS: Significant improvements were shown for KOOS-PF in both subgroups (strong: (pre) = 63.84 & (post) = 71.49 and weak and tight: (pre) = 53.03 & (post) = 72.73), although only improvements in the weak and tight group exceeded the minimum clinically important difference (MCID). In addition, significant reductions in peak patellofemoral stress were shown in both subgroups (strong: (pre) = 6.82 & (post) = 6.39KPa/BW and weak and tight: (pre) = 7.66 & (post) = 6.28KPa/BW), although only reductions in the weak and tight group exceeded the MCID. CONCLUSIONS: Semi-custom insoles may be a mechanism to reduce patellofemoral pain symptoms in recreational runners from the weak and tight subgroup. It is proposed that this improvement was mediated through reductions in patellofemoral loading in this subgroup.

Delivering Intensive Rehabilitation in Stroke: Factors Influencing Implementation.

Background: The evidence base for stroke rehabilitation recommends intensive and repetitive task-specific practice, as well as aerobic exercise. However, translating these -evidence-based interventions from research into clinical practice remains a major -challenge. Objective: The objective of this study was to investigate factors influencing implementation of higher-intensity activity in stroke rehabilitation settings. Design: This qualitative study used a cross-sectional design. Methods: Semi-structured interviews were conducted with rehabilitation therapists from 4 sites across 2 Canadian provinces who had experience in delivering a higher-intensity intervention as part of a clinical trial (Determining Optimal post-Stroke Exercise [DOSE]). An interview guide was developed, and data were analyzed using implementation frameworks. Results: Fifteen therapists were interviewed before data saturation was reached. Therapists and patients generally had positive experiences regarding high-intensity interventions. However, therapists felt they would adapt the protocol to accommodate their beliefs about ensuring movement quality. The requirement for all patients to have a graded exercise test and the use of sensors (eg, heart rate monitors) gave therapists confidence to push patients harder than they normally would. Paradoxically, a system that enables routine graded exercise testing and the availability of staff and equipment contribute challenges for implementation in everyday practice. Conclusions: Even therapists involved in delivering a high-intensity intervention as part of a trial wanted to adapt it for clinical practice; therefore, it is imperative that researchers are explicit regarding key intervention components and what can be adapted to help ensure implementation fidelity. Changes in therapists' beliefs and system-level changes (staffing and resources) are likely necessary to facilitate higher-intensity rehabilitation in practice.

Is keep/refer decision making an integral part of national guidelines for the physiotherapy profession within Europe? A review.

BACKGROUND: Keep/refer decision as the ability to independently determine whether a patient's condition is suitable for physiotherapy management (keep) or not (refer), is regarded as an core element in the World Confederation of Physical Therapists' (WCPT) Guideline for Standards of Physical Therapy Practice. However, it is currently unknown how individual European countries have implemented this in their national guidelines. OBJECTIVES: To determine if keep/refer decision making abilities are an integral part of national guidelines for the physiotherapy profession of member countries of the European Network of Physiotherapy in Higher Education (ENPHE). DATA SOURCES: A review was performed including medical databases, the grey literature and personal correspondence with professional ENPHE member associations. To gain the information of interest, all eligible documents were reviewed. RESULTS: 11 national guidelines for the physiotherapy profession could be obtained. Two additional member associations use European guidelines as their national ones. Despite the fact that in the WCPT guidelines keep/refer decision making abilities are clearly described as a core element, there exists huge inconsistency as to how various European (with direct and non direct access systems) countries have included them in their national guidelines. CONCLUSION: Despite the fact that most ENPHE member countries deem a close collaboration between health care professionals important and that physiotherapists should know the limitation of their expertise, keep/refer decision making abilities as explicitly stated in the WCPT guidelines were not included in the majority of guidelines that were reviewed.

Effect of three cueing devices for people with Parkinson's disease with gait initiation difficulties.

BACKGROUND: Freezing of gait (FOG) remains one of the most common debilitating aspects of Parkinson's disease and has been linked to injuries, falls and reduced quality of life. Although commercially available portable cueing devices exist claiming to assist with overcoming freezing; their immediate effectiveness in overcoming gait initiation failure is currently unknown. This study investigated the effects of three different types of cueing device in people with Parkinson's disease who experience freezing. METHODS: Twenty participants with idiopathic Parkinson's disease who experienced freezing during gait but who were able to walk short distances indoors independently were recruited. At least three attempts at gait initiation were recorded using a 10 camera Qualisys motion analysis system and four force platforms. Test conditions were; Laser Cane, sound metronome, vibrating metronome, walking stick and no intervention. RESULTS: During testing 12 of the 20 participants had freezing episodes, from these participants 100 freezing and 91 non-freezing trials were recorded. Clear differences in the movement patterns were seen between freezing and non-freezing episodes. The Laser Cane was most effective cueing device at improving the forwards/backwards and side to side movement and had the least number of freezing episodes. The walking stick also showed significant improvements compared to the other conditions. The vibration metronome appeared to disrupt movement compared to the sound metronome at the same beat frequency. CONCLUSION: This study identified differences in the movement patterns between freezing episodes and non-freezing episodes, and identified immediate improvements during gait initiation when using the Laser Cane over the other interventions.

Are there three main subgroups within the patellofemoral pain population? A detailed characterisation study of 127 patients to help develop targeted intervention (TIPPs).

BACKGROUND: Current multimodal approaches for the management of non-specific patellofemoral pain are not optimal, however, targeted intervention for subgroups could improve patient outcomes. This study explores whether subgrouping of non-specific patellofemoral pain patients, using a series of low cost simple clinical tests, is possible. METHOD: The exclusivity and clinical importance of potential subgroups was assessed by applying à priori test thresholds (1 SD) from seven clinical tests in a sample of adult patients with non-specific patellofemoral pain. Hierarchical clustering and latent profile analysis, were used to gain additional insights into subgroups using data from the same clinical tests. RESULTS: 130 participants were recruited, 127 had complete data: 84 (66%) female, mean age 26 years (SD 5.7) and mean body mass index 25.4 (SD 5.83), median (IQR) time between onset of pain and assessment was 24 (7-60) months. Potential subgroups defined by the à priori test thresholds were not mutually exclusive and patients frequently fell into multiple subgroups. Using hierarchical clustering and latent profile analysis three subgroups were identified using 6 of the 7 clinical tests. These subgroups were given the following nomenclature: (1) 'strong', (2) 'weak and tighter' and (3) 'weak and pronated foot'. CONCLUSIONS: We conclude that three subgroups of patellofemoral patients may exist based on the results of six clinical tests which are feasible to perform in routine clinical practice. Further research is needed to validate these findings in other data sets and, if supported by external validation, to see if targeted interventions for these subgroups improve patient outcomes.

Targeted interventions for patellofemoral pain syndrome (TIPPS): classification of clinical subgroups.

INTRODUCTION: Patellofemoral pain (PFP) can cause significant pain leading to limitations in societal participation and physical activity. An international expert group has highlighted the need for a classification system to allow targeted intervention for patients with PFP; we have developed a work programme systematically investigating this. We have proposed six potential subgroups: hip abductor weakness, quadriceps weakness, patellar hypermobility, patellar hypomobility, pronated foot posture and lower limb biarticular muscle tightness. We could not uncover any evidence of the relative frequency with which patients with PFP fell into these subgroups or whether these subgroups were mutually exclusive. The aim of this study is to provide information on the clinical utility of our classification system. METHODS AND ANALYSIS: 150 participants will be recruited over 18 months in four National Health Services (NHS) physiotherapy departments in England. INCLUSION CRITERIA: adults 18-40 years with PFP for longer than 3 months, PFP in at least two predesignated functional activities and PFP elicited by clinical examination. EXCLUSION CRITERIA: prior or forthcoming lower limb surgery; comorbid illness or health condition; and lower limb training or pregnancy. We will record medical history, demographic details, pain, quality of life, psychomotor movement awareness and knee temperature. We will assess hip abductor and quadriceps weakness, patellar hypermobility and hypomobility, foot posture and lower limb biarticular muscle tightness. The primary analytic approach will be descriptive. We shall present numbers and percentages of participants who meet the criteria for membership of (1) each of the subgroups, (2) none of the subgroups and (3) multiple subgroups. Exact (binomial) 95% CIs for these percentages will also be presented. ETHICS AND DISSEMINATION: This study has been approved by National Research Ethics Service (NRES) Committee North West-Greater Manchester North (11/NW/0814) and University of Central Lancashire (UCLan) Built, Sport, Health (BuSH) Ethics Committee (BuSH 025). An abstract has been accepted for the third International Patellofemoral Pain Research Retreat, Vancouver, September 2013.

Building the research capacity of clinical physical therapists using a participatory action research approach.

BACKGROUND: This 2-year study explored the experiences of clinical physical therapists who used a participatory action research (PAR) approach to learn about the practice of clinical research. OBJECTIVES: The aim of this study was to explore the experiences of physical therapists who were conducting clinical research, facilitated by a PAR approach. DESIGN: A mixed-methods research design was used. METHODS: Physical therapists completed questionnaires, were interviewed, and participated in focus groups prior to and after the 1-year intervention and 1 year later. The research facilitator took field notes. Questionnaire data were analyzed descriptively, and themes were developed from the qualitative data. Twenty-five therapists took part in 4 self-selected groups. RESULTS: Three groups actively participated in the PAR research projects (n=14). The remaining 11 therapists decided not to be involved in clinical research projects but took part in the study as participants. After 1 year, one group completed the data collection phase of their research project, and a second group completed their ethics application. The third group ceased their research project but hosted a journal club session. At completion of the study, the experiences of the physical therapists were positive, and their confidence in conducting research and orientation toward research had increased. The perceptions of physical therapists toward research, relationships among individuals, and how the clinical projects were structured influenced the success of the projects. LIMITATIONS: Only physical therapists of one hospital and no other health care practitioners were included in this study. CONCLUSIONS: Fourteen physical therapists divided among 3 PAR groups were overall positive about their experiences when they conducted a research project together. This finding shows that a PAR approach can be used as a novel tool to stimulate research participation in clinics.
