RESUMO
PURPOSE: The purpose of the study was to investigate perceived determinants of physical activity (PA) maintenance following supervised exercise oncology rehabilitation and the acceptability of a remote coaching intervention during this period. METHODS: A phenomenological qualitative study with semi-structured interviews was conducted. Nineteen participants (16 women, 3 men) were recruited from the intervention (n = 12) and control group (n = 7) of a randomized controlled trial on the effectiveness of remote coaching following hospital-based, supervised exercise oncology rehabilitation. Participants in the intervention group received a 6-month remote coaching intervention after completing the exercise program, aimed at stimulating PA maintenance. The interviews were based on the Capability, Opportunity, and Motivation model of Behaviour (COM-B model) and the framework of acceptability (TFA) and were coded using template analysis. RESULTS: Key themes regarding determinants of PA maintenance were self-efficacy, PA habits, accountability, physical complaints, and facilities. Remote coaching was perceived acceptable because it stimulated PA maintenance by offering a source of structure and social support and thereby increased accountability. Moreover, it improved confidence to perform PA, leading to increased levels of self-efficacy. The remote nature of the intervention was perceived as convenient by some of the participants, while others would have preferred additional physical appointments. CONCLUSIONS: Cancer survivors considered remote coaching acceptable to stimulate PA maintenance following supervised rehabilitation. Interventions should focus on increasing accountability, self-efficacy, forming habits, and helping cancer survivors to overcome barriers. IMPLICATIONS FOR CANCER SURVIVORS: The ability to maintain PA beyond supervised exercise oncology programs depends on many determinants. Remote coaching interventions have potential to target individually relevant determinants following exercise programs in cancer survivors.
RESUMO
BACKGROUND: Older adults admitted with an acute medical illness spent little time active during hospitalisation and this has been associated with negative health outcomes. Understanding which barriers and enablers influence the physical activity behaviour of hospitalised older adults is a first step towards identifying potentially modifiable factors and developing, evaluating and implementing targeted interventions aimed at increasing their physical activity behaviour. Using a theoretical framework has been found to be more successful in changing behaviour than using a non-theory driven approach. This study aimed to explore barriers and enablers to physical activity behaviour in older adults admitted to a hospital with an acute medical illness, as perceived by patients and healthcare professionals, and to categorise them using the Theoretical Domains Framework (TDF). METHODS: A qualitative study was conducted at a combined university and regional hospital in the Netherlands between January 2019 and February 2020. Older adults (≥70 years) admitted with an acute medical illness, and healthcare professionals (nurses, physicians, physiotherapists) were recruited using purposive sampling. Semi-structured interviews were audiotaped, transcribed and analysed using directed qualitative content analysis. Barriers and enablers to physical activity behaviour during hospitalisation were identified and coded using the TDF. RESULTS: Meaning saturation was determined after interviews with 12 patients and 16 healthcare professionals. A large number of barriers and enablers were identified and each categorised to 11 of the 14 domains of the TDF. The 'Environmental Context and Resources' domain in particular yielded many examples, and revealed that the hospital environment exerts an inactivating influence on patients. CONCLUSIONS: The large number of identified barriers and enablers highlights the complexity of influencing older adults' physical activity behaviour during hospitalisation. This overview of barriers and enablers to physical activity behaviour in older adults admitted to a hospital with an acute medical illness represents an initial step towards developing, evaluating and implementing theory-informed behaviour change interventions to improve hospitalised older adults' physical activity levels. It can assist clinicians and researchers in selecting modifiable factors that can be targeted in future interventions.

BACKGROUND: Students perceive reflective writing as difficult. Concept mapping may be an alternative format for reflection, which provides support while allowing students to freely shape their thoughts. We examined (1) the quality of reflection in reflective concept maps created by first-year medical students and (2) students' perceptions about concept mapping as a tool for reflection. METHODS: Mixed-method study conducted within the medical curriculum of Maastricht University, The Netherlands, consisting of: (1) Analysis of the quality of reflection in 245 reflective concept maps created by 40 first-year students. Reflection quality was analysed by assessing focus of reflection (technical/practical/sensitising) and depth of reflection (description/justification/critique/discussion). (2) Semi-structured interviews with 22 students to explore perceived effectiveness of reflective concept mapping. RESULTS: Depth of reflection reached at least the level of critique in 82% of maps. Three factors appeared to affect the perceived effectiveness of concept mapping for reflection: (1) reflective concept map structure; (2) alertness to meaningful experiences in practice and (3) learning by doing. CONCLUSION: These results yielded supportive evidence for concept mapping as a useful technique to teach novice learners the basics of effective reflection. Meaningful implementation requires a delicate balance between providing a supportive structure and allowing flexibility for the student.

OBJECTIVE: To investigate the effect of replacing canes with an elasticated orthotic-garment on balance and gait-function in chronic stroke survivors. DESIGN: Experimental, N-of-1 series with a replicated, ABC design with randomised phase duration in a home setting. PARTICIPANTS: Four cane using chronic stroke survivors (P1-4). INTERVENTIONS: Phase A (9-12 weeks) cane-walking "as usual" to establish baseline values; Phase B (9-16 weeks) intervention: orthotic-garment worn throughout the day with maximal cane-use reduction; Phase C (9-10 weeks) participant-determined follow-up: either no walking-aid, orthotic-garment or cane. OUTCOME MEASURES: Primary: Functional-Gait-Assessment (FGA), Secondary: Trunk-sway during walking measured as Total-Angle-Area (TAA°2) in frontal and sagittal-planes, both measured weekly. RESULTS: Visual and statistical analysis of results showed significant improvements in FGA from phase A to B in all participants. Improvement continued in phase C in P2, stabilized in P1 and P4 and deteriorated in P3. A Minimal-Clinical-Important-Difference of 6 points-change was achieved in P2 & P4. Trunk-sway reduced during walking, indicating increased stability, in two participants from phase A to B and in three participants from A to C but no TAA changes were statistically significant. In phase C participant-selected walking-aids were: P1 cane-usage reduced by 25%, P2 independent-walking with no assistive-device, S3 usual cane-usage, P4 orthotic-garment with reduced cane-usage 2-3 days-a-week, usual cane-usage 4-5 days. CONCLUSIONS: Although walking ability is multifactorial these results indicate that the choice of walking-aids can have a specific and clinically relevant impact on gait following stroke. "Hands-free" assistive-devices may be more effective than canes in improving gait-function in some patients. CLINICALTRIALS. GOV ID: NCT03642444.

Purpose: The purpose of this qualitative study was to explore how stroke patients with unilateral spatial neglect experience; (a) performance in activities of daily living; (b) alterations in bodily perceptions; and (c) personal hopes and expectations, looking at the period between stroke onset and discharge from inpatient rehabilitation.Materials and methods: We conducted individual semi-structured interviews with 7 (5 men, 2 women, mean age 69 years) consecutively sampled participants. All interviews were transcribed verbatim and analyzed using thematic analysis.Findings: Participants' experiences were captured in three over-arching themes: "unawareness of neglect," "emergent awareness for neglect-related difficulties," and "comparing the new life with the old one." Findings showed that participants progressed from initial unawareness to emergent awareness for their neglect-related difficulties over the course of rehabilitation. Comparing their current life situation with the one before their stroke triggered feelings of uncertainty and regret, with associated decreased pleasure in meaningful activities.Conclusions: This study informs health professionals regarding personal experiences of orientation in and reorganization of life of stroke patients with unilateral spatial neglect. The findings highlight that being aware of neglect-related deficits is a prerequisite for using coping strategies and incorporating them in daily life. Possible therapeutic strategies that fit the current stage of recovery and level of awareness are discussed.IMPLICATIONS FOR REHABILITATIONSymptoms of unilateral spatial neglect and anosognosia are most common after right hemispheric stroke, both being predictors of poorer functional outcome during rehabilitation.Patients' regaining some awareness of their impairments is a prerequisite for successful treatment and for engagement in neglect-specific interventions.Health care providers should carefully examine the "state of awareness" of the patient and adapt their therapeutic approach accordingly.This check should frequently be repeated over the course of rehabilitation, as awareness changes at different paces for each patient.

Current knowledge of neural and neuromuscular processes controlling gait and movement as well as an understanding of how these mechanisms change following stroke is an important basis for the development of effective rehabilitation interventions. To support the translation of findings from basic research into useful treatments in clinical practice, up-to-date neuroscience should be presented in forms accessible to all members of the multidisciplinary team. In this review we discuss aspects of cortical control of gait and movement, muscle synergies as a way of translating cortical commands into specific muscle activity and as an efficient means of reducing neural and musculoskeletal redundancy. We discuss how these mechanisms change following stroke, potential consequences for gait rehabilitation, and the prescription and use of walking-aids as well as areas requiring further research.

BACKGROUND: Adherence to an exercise programme impacts the outcome of physiotherapy treatment in patients with non-specific low back pain. OBJECTIVES: The aim of this study was to explore the patients' perspectives on long term adherence to such exercise programmes. DESIGN: This qualitative study was embedded in a randomised controlled trial (RCT) which compared the effectiveness of two types of exercise programme on patients with nonspecific low back pain. METHODS: Answers from 44 participants to three open-ended questions were analysed using thematic analysis. RESULTS/FINDINGS: Patients' perceptions related to the following themes: 1) the role of knowledge in long-term exercise adherence; 2) strategies to support exercise adherence; 3) barriers to exercise adherence 4) the role of perceived effects of exercise. CONCLUSIONS: Adherence to long-term exercise is supported through knowledge of the exercises and correct performance. A self-initiated training strategy is the most successful in the perception of participants. Individually supervised physiotherapy treatment that includes coaching towards strategies for post-treatment long term exercise behaviour is recommended.

BACKGROUND: Many aspects of post-stroke gait-rehabilitation are based on low-level evidence or expert opinion. Neuroscientific principles are often not considered when evaluating the impact of interventions. The use of walking-aids including canes and rollators, although widely used for long periods, has primarily been investigated to assess the immediate kinetic, kinematic or physiological effects. The long-term impact on neural structures und functions remains unclear. METHODS: A literature review of the function of and factors affecting plasticity of spinal interneuronal-networks and central-pattern-generators (CPG) in healthy and post-stroke patients. The relevance of these mechanisms for gait recovery and the potential impact of walking-aids is discussed. RESULTS: Afferent-input to spinal-networks influences motor-output and spinal and cortical plasticity. Disrupted input may adversely affect post-stroke plasticity and functional recovery. Joint and muscle unloading and decoupling from four-limb CPG control may be particularly relevant. CONCLUSIONS: Canes and rollators disrupt afferent-input and may negatively affect the recovery of gait.

PURPOSE: Thoracic paravertebral block (TPVB) may be an alternative to thoracic epidural analgesia. A detailed knowledge of the anatomy of the TPV-space (TPVS), content and adnexa is essential in understanding the clinical consequences of TPVB. The exploration of the posterior TPVS accessibility in this study allows (1) determination of the anatomical boundaries, content and adnexa, (2) description of an ultrasound-guided spread of low and high viscous liquid. METHODS: In two formalin-fixed specimens, stratification of the several layers and the 3D-architecture of the TPVS were dissected, observed and photographed. In a third unembalmed specimen, ultrasound-guided posterolateral injections at several levels of the TPVS were performed with different fluids. RESULTS: TPVS communicated with all surrounding spaces including the segmental dorsal intercostal compartments (SDICs) and the prevertebral space. TPVS transitions to the SDICs were wide, whereas the SDICs showed narrowed transitions to the lateral intercostal spaces at the costal angle. Internal subdivision of the TPVS in a subendothoracic and an extra-pleural compartment by the endothoracic fascia was not observed. Caudally injected fluids spread posteriorly to the costodiaphragmatic recess, showing segmental intercostal and slight prevertebral spread. CONCLUSIONS: Our detailed anatomical study shows that TPVS is a potential space continuous with the SDICs. The separation of the TPVS in a subendothoracic and an extra-pleural compartment by the endothoracic fascia was not observed. Based on the ultrasound-guided liquid spread we conclude that the use of a more lateral approach might increase the probability of intravascular puncture or catheter position.

BACKGROUND CONTEXT: The amount of vertebral rotation in the axial plane is of key importance in the prognosis and treatment of adolescent idiopathic scoliosis (AIS). Current methods to determine vertebral rotation are either designed for use in analogue plain radiographs and not useful in digital images, or lack measurement precision and are therefore less suitable for the follow-up of rotation in AIS patients. PURPOSE: This study aimed to develop a digital X-ray software tool with high measurement precision to determine vertebral rotation in AIS, and to assess its (concurrent) validity and reliability. STUDY DESIGN/SETTING: In this study a combination of basic science and reliability methodology applied in both laboratory and clinical settings was used. METHODS: Software was developed using the algorithm of the Perdriolle torsion meter for analogue AP plain radiographs of the spine. Software was then assessed for (1) concurrent validity and (2) intra- and interobserver reliability. Plain radiographs of both human cadaver vertebrae and outpatient AIS patients were used. Concurrent validity was measured by two independent observers, both experienced in the assessment of plain radiographs. Reliability-measurements were performed by three independent spine surgeons. RESULTS: Pearson correlation of the software compared with the analogue Perdriolle torsion meter for mid-thoracic vertebrae was 0.98, for low-thoracic vertebrae 0.97 and for lumbar vertebrae 0.97. Measurement exactness of the software was within 5° in 62% of cases and within 10° in 97% of cases. Intraclass correlation coefficient (ICC) for inter-observer reliability was 0.92 (0.91-0.95), ICC for intra-observer reliability was 0.96 (0.94-0.97). CONCLUSIONS: We developed a digital X-ray software tool to determine vertebral rotation in AIS with a substantial concurrent validity and reliability, which may be useful for the follow-up of vertebral rotation in AIS patients.

STUDY DESIGN: Diffusion tensor magnetic resonance imaging (DT-MRI) reconstruction of lumbar erector spinae (ES) compared with cadaver dissection. OBJECTIVE: The aim of this study was to reconstruct the human lumbar ES from in vivo DT-MRI measurements and to compare the results with literature and cadaver dissection. SUMMARY OF BACKGROUND DATA: DT-MRI enables 3-dimensional in vivo reconstruction of muscle architecture. Insight in ES architecture may improve the understanding of low back function. Furthermore, DT-MRI reconstructions allow individualized biomechanical modeling, which may serve as a clinical tool in injury evaluation and in improvement of understanding of pathologies like scoliosis. MATERIALS AND METHODS: The lumbar spine of 1 healthy male volunteer was scanned using a 3.0 T clinical MRI scanner. MRI data acquisition consisted of 3 parts: (1) high-resolution T1-weighted turbo spin echo for anatomical reference; (2) DT-MRI measurements for fiber tractography; (3) dual echo gradient echo sequence for signal correction purposes. After processing, DT-MRI data were exported to a custom-built software program for fiber tractography. The resulting reconstructions were anatomically validated by comparison with cadaver dissection and literature. RESULTS: DT-MRI reconstruction of 4 parts of the lumbar ES (thoracic part of iliocostalis lumborum, lumbar part of iliocostalis lumborum, thoracic part of longissimus thoracis, and lumbar part of longissimus thoracis) adequately reflected its complex geometry. Some inaccuracies were found in reconstruction details. DT-MRI reconstructions were generally in agreement with anatomical descriptions from literature and with findings in a dissected cadaver specimen. CONCLUSIONS: DT-MRI enables anatomically valid reconstruction of ES architecture. However, for reliable reconstruction of the smallest fascicles and attachments a higher resolution or application of higher-order models is needed. Reconstructions can be used as input for estimation of muscle architecture parameters in individualized biomechanical modeling. Such models are promising as a tool in clinical evaluation and in research of low back pain mechanisms.

BACKGROUND: Exercise is an effective treatment for patients with sub-acute and chronic low back pain (LBP). Patients with a movement control impairment (MCI) can be diagnosed as a subgroup of patients with LBP. Unknown is which exercise intervention is most beneficial for this subgroup. This study assessed the short-term effect of a specific exercise program targeting movement control impairment versus general exercise treatment on disability in patients with LBP and MCI. METHODS: In a multicentre parallel group randomised controlled pragmatic trial, patients with sub-acute and chronic LBP were included. Further inclusion criteria were disability of ≥5 points on the Roland-Morris Disability Questionnaire and ≥2 positive tests out of a set of 6 movement control impairment tests. A total of 106 patients were randomly assigned to either tailored movement control exercise intervention (MC, n = 52) or a general exercise intervention (GE, n = 54); both 9-18 individual treatment sessions, over a maximum of 12 weeks. The primary outcome was disability measured with the Patient Specific Functional scale (PSFS). Secondary outcome was the Roland-Morris disability scale (RMDQ). Measurements were taken pre- and posttreatment. RESULTS: No significant difference was found following the treatment period. Baseline-adjusted between-group mean difference for the PSFS was 0.5 (SD = 0.5; p = 0.32) in favour of MC exercises. The Roland-Morris Disability Questionnaire revealed a significant, but not clinically relevant, between-group difference of 2.0 points (SD = 0.8; p = 0.01). CONCLUSION: Disability in LBP patients was reduced considerably by both interventions. However, the limited contrast between the two exercise programs may have influenced outcomes.

Accelerated rehabilitation following hip fracture and joint replacement, including early unrestricted weight-bearing and muscle strengthening, has gained importance in hastening functional recovery and hospital discharge. The influence of walking aids on these parameters is sparsely investigated. In this case report, we document the effect of walking with crutches; an orthotic garment and strapping system, TheraTogs; and no walking aids over 3-4-week periods on walking speed, trunk sway, and muscle activity measured with electromyography (EMG). The patient was a 49-year-old female showing delayed healing following a conservatively treated avulsion fracture of the greater trochanter 12 weeks previously with a 14-year history of total hip arthroplasty. EMG analysis showed muscle activity increased with TheraTogs and decreased with crutches compared with walking with no aids. Walking speed improved at a faster rate in the TheraTogs phase than in the crutches phase and reduced in no-walking-aids phase. Mean speed (SD) for each phase was: crutches 1.11 (0.08) m/s, TheraTogs 1.35 (0.11) m/s, and no-aids 1.19 (0.14) m/s. Trunk sway increased in the crutch and no-aids phases, and became more stable in the TheraTogs phase. In this patient, function and recovery rate of all measured parameters increased more in the TheraTogs phase than the crutches or no-aids phase. This may be because muscle activity was facilitated enabling active support of recovering structures.

BACKGROUND: Exercise is an effective treatment for patients with sub-acute and chronic non-specific low back pain (NSLBP). Previous studies have shown that a subgroup of patients with NSLBP and movement control impairment (MCI) can be diagnosed with substantial reliability. However, which type of exercises are most beneficial to this subgroup is still unknown. OBJECTIVES: The effectiveness of a specific exercise treatment to improve movement control was tested in this study. METHODS: Using a multicentre randomised controlled trial (RCT), we compared exercises that targeted MCI (MC) with a general exercise (GE) treatment. After randomisation, patients in both groups n(MC = 52; GE = 54) were treated in eight private physiotherapy practices and five hospital outpatient physiotherapy centres. Follow-up measurements were taken at post-treatment, six months and 12 months. The primary outcome measurement was the Patient Specific Function Scale (PSFS). RESULTS: PSFS showed no difference between groups after treatment, or at six months and 12 months. Secondary outcome analysis for pain and disability, measured with the Graded Chronic Pain scale and the Roland Morris Disability Questionnaire respectively, showed that a small improvement post-treatment levelled off over the long term. Both groups improved significantly (p < 0.001) over the course of one year. CONCLUSION: This study found no additional benefit of specific exercises targeting MCI.

BACKGROUND: Little information exists about the role of fear-avoidance beliefs and catastrophizing in subacromial pain syndrome. OBJECTIVE: The purpose of this study was to investigate the associations among pain, catastrophizing, fear, and disability and the contribution of fear-avoidance beliefs to disability at baseline and at 3-month follow-up. DESIGN: A cross-sectional and longitudinal analysis was conducted. METHODS: Baseline demographic and clinical data, including fear-avoidance beliefs and catastrophizing, of 90 patients were assessed for this analysis. Disability was measured with the Shoulder Pain and Disability Index at baseline and at 3-month follow-up. First, bivariate and partial correlations were calculated among pain, fear-avoidance beliefs, catastrophizing, and disability, based on the fear-avoidance model. Second, the contribution of fear-avoidance beliefs to disability at baseline and at 3-month follow-up was examined with hierarchical regression analyses. RESULTS: Correlations between clinical variables and disability were largely in line with the fear-avoidance model. Regression analyses identified a significant contribution of fear-avoidance beliefs to baseline disability but not to disability at 3 months. LIMITATIONS: Patients with subacromial pain syndrome were studied; therefore, the results should be transferred with caution to other diagnoses. A modified version of the Fear-Avoidance Beliefs Questionnaire was used, which was not validated for this patient group. CONCLUSIONS: Fear-avoidance beliefs contribute significantly to baseline disability but not to disability change scores after 3-month follow-up. Duration of complaints and baseline disability were the main factors influencing disability change scores. Although the results help to improve understanding of the role of fear-avoidance beliefs, further studies are needed to fully understand the influence of psychological and clinical factors on the development of disability in patients with subacromial shoulder pain.

BACKGROUND: Anatomical validation studies of cervical ultrasound images are sparse. Validation is crucial to ensure accurate interpretation of cervical ultrasound images and to develop standardized reliable ultrasound procedures to identify cervical anatomical structures. The aim of this study was to acquire validated ultrasound images of cervical bony structures and to develop a reliable method to detect and count the cervical segmental levels. METHODS: An anatomical model of a cervical spine, embedded in gelatin, was inserted in a specially developed measurement device. This provided ultrasound images of cervical bony structures. Anatomical validation was achieved by laser light beams projecting the center of the ultrasound image on the cervical bony structures through a transparent gelatin. RESULTS: Anatomically validated ultrasound images of different cervical bony structures were taken from dorsal, ventral, and lateral perspectives. Potentially relevant anatomical landmarks were defined and validated. Test/retest analysis for positioning showed a reproducibility with an intraclass correlation coefficient for single measures of 0.99. Besides providing validated ultrasound images of bony structures, this model helped to develop a method to detect and count the cervical segmental levels in vivo at long-axis position, in a dorsolateral (paramedian) view at the level of the laminae, starting from the base of the skull and sliding the ultrasound probe caudally. CONCLUSIONS: Ultrasound bony images of the cervical vertebrae were validated with an in vitro model. Anatomical bony landmarks are the mastoid process, the transverse process of C1, the tubercles of C6 and C7, and the cervical laminae. Especially, the cervical dorsal laminae serve best as anatomical bony landmarks to reliably detect the cervical segmental levels in vivo.

Anatomy education often consists of a combination of lectures and laboratory sessions, the latter frequently including surface anatomy. Studying surface anatomy enables students to elaborate on their knowledge of the cadaver's static anatomy by enabling the visualization of structures, especially those of the musculoskeletal system, move and function in a living human being. A recent development in teaching methods for surface anatomy is body painting, which several studies suggest increases both student motivation and knowledge acquisition. This article focuses on a teaching approach and is a translational contribution to existing literature. In line with best evidence medical education, the aim of this article is twofold: to briefly inform teachers about constructivist learning theory and elaborate on the principles of constructive, collaborative, contextual, and self-directed learning; and to provide teachers with an example of how to implement these learning principles to change the approach to teaching surface anatomy. Student evaluations of this new approach demonstrate that the application of these learning principles leads to higher student satisfaction. However, research suggests that even better results could be achieved by further adjustments in the application of contextual and self-directed learning principles. Successful implementation and guidance of peer physical examination is crucial for the described approach, but research shows that other options, like using life models, seem to work equally well. Future research on surface anatomy should focus on increasing the students' ability to apply anatomical knowledge and defining the setting in which certain teaching methods and approaches have a positive effect.

BACKGROUND: Annually, some 9000 people in Switzerland suffer a first time stroke. Of these 60% are left with moderate to severe walking disability. Evidence shows that rehabilitation techniques which emphasise activity of the hemiplegic side increase ipsilesional cortical plasticity and improve functional outcomes. Canes are commonly used in gait rehabilitation although they significantly reduce hemiplegic muscle activity. We have shown that an orthosis "TheraTogs" (a corset with elasticated strapping) significantly increases hemiplegic muscle activity during gait. The aim of the present study is to investigate the long term effects on the recovery of gait, balance and social participation of gait rehabilitation with TheraTogs compared to gait rehabilitation with a cane following first time acute stroke. METHODS/DESIGN: Multi-centre, single blind, randomised trial with 120 patients after first stroke. When subjects have reached Functional Ambulation Category 3 they will be randomly allocated into TheraTogs or cane group. TheraTogs will be applied to support hip extensor and abductor musculature according to a standardised procedure. Cane walking held at the level of the radial styloid of the sound wrist. Subjects will walk throughout the day with only the assigned walking aid. Standard therapy treatments and usual care will remain unchanged and documented. The intervention will continue for five weeks or until patients have reached Functional Ambulation category 5. Outcome measures will be assessed the day before begin of intervention, the day after completion, 3 months, 6 months and 2 years. PRIMARY OUTCOME: Timed "up and go" test, secondary outcomes: peak surface EMG of gluteus maximus and gluteus medius, activation patterns of hemiplegic leg musculature, temporo-spatial gait parameters, hemiplegic hip kinematics in the frontal and sagittal planes, dynamic balance, daily activity measured by accelerometry, Stroke Impact Scale. Significance levels will be 5% with 95% CI's. IntentionToTreat analyses will be performed. Descriptive statistics will be presented. DISCUSSION: This study could have significant implications for the clinical practice of gait rehabilitation after stroke, particularly the effect and appropriate use of walking aids.The results could be important for the development of clinical guidelines and for the socio-economic costs of post-stroke care.

BACKGROUND: Non-specific low back pain (NSLBP) in subacute and chronic stages can be treated effectively with exercise therapy. Research guidelines recommend evaluating different treatments in defined subgroups of patients with NSLBP. A subgroup of patients with movement control impairment (MCI) improved significantly on patient specific function and disability in a previous case series after movement control exercises. METHODS/DESIGN: In a randomised controlled trial (RCT) we will compare the effectiveness of movement control and general exercise in patients with MCI. 106 participants aged 18 - 75 will be recruited in 5 outpatient hospital departments and 7 private practices.Patients randomly assigned to the movement control exercise group will be instructed to perform exercises according to their MCI. The general exercise group will follow an exercise protocol aimed at improving endurance and flexibility. Patients in both groups will receive 9 - 18 treatments and will be instructed to do additional exercises at home.The primary outcome is the level of disability assessed using the patient specific functional scale (PSFS) which links the perceived pain to functional situations and is measured before treatment and at 6 and 12 months follow-up. Secondary outcomes concern low back pain related disability (Roland Morris questionnaire, RMQ), graded chronic pain scale (GCPS), range of motion and tactile acuity. DISCUSSION: To our knowledge this study will be the first to compare two exercise programs for a specific subgroup of patients with NSLBP and MCI. Results of this study will provide insight into the effectiveness of movement control exercise and contribute to our understanding of the mechanisms behind MCI and its relation to NSLBP. TRIAL REGISTRATION: Current Controlled Trials ISRCTN80064281.

OBJECTIVE: To confirm previous findings that hip abductor activity measured by electromyography (EMG) on the side contralateral to cane use is reduced during walking in stroke patients. To assess whether an orthosis (TheraTogs) or hip abductor taping increase hemiplegic hip abductor activity compared with activity during cane walking or while walking without aids. To investigate the effect of each condition on temporo-spatial gait parameters. DESIGN: Randomized, within-participant experimental study. SETTING: Gait laboratory. SUBJECTS: Thirteen patients following first unilateral stroke. INTERVENTION: Data collection over six gait cycles as subjects walked at self-selected speed during: baseline (without aids) and in randomized order with (1) hip abductor taping, (2) TheraTogs, (3) cane in non-hemiplegic hand. MAIN MEASURES: Peak EMG of gluteus medius and tensor fascia lata and temporo-spatial gait parameters. RESULTS: Cane use reduced EMG activity in gluteus medius from baseline by 21.86%. TheraTogs increased it by 16.47% (change cane use-TheraTogs P = 0.001, effect size = -0.5) and tape by 5.8% (change cane use-tape P = 0.001, effect size = -0.46). In tensor fascia lata cane use reduced EMG activity from baseline by 19.14%. TheraTogs also reduced EMG activity from baseline by 1.10% (change cane use-TheraTogs P = 0.009, effect size -0.37) and tape by 3% (not significant). Gait speed (m/s) at: baseline 0.44, cane use 0.45, tape 0.48, TheraTogs 0.49. CONCLUSION: Hip abductor taping and TheraTogs increase hemiplegic hip abductor activity and gait speed during walking compared with baseline and cane use.
