Patient attitudes and experiences towards exercise during oncological treatment. A qualitative systematic review.

PURPOSE: Exercise and physical activity (PA) during oncological treatment have many benefits. However, PA levels and adherence are often low. This systematic review of qualitative literature aims to explore the experience and the perceived barriers and facilitators to exercise and physical activity during treatment. METHODS: A systematic search of the published literature was carried out in the Embase and Medline databases; full details for the protocol can be found in the Prospero database (CRD42022371206). Studies eligible for inclusion were qualitative and included participants that were either currently undergoing oncological treatment or had finished treatment within the last 6 months. The findings from each study were tabulated and synthesised into analytical themes. RESULTS: Eighteen full texts from 309 studies met inclusion criteria with a total of 420 participants including both curative and palliative treatment intents. Four overarching themes were generated: (1) Facilitators; (2) Barriers; (3) Experience of PA/exercise and (4) Transforming attitudes. Sub-themes that showed perceptions of PA or exercise during treatment were positive, and seeing personal positive change was highly motivating, especially in a group class setting. Barriers included lack of support or guidance from healthcare professionals (HCPs), environmental challenges and disease burden/fear or worsening symptoms. CONCLUSIONS: Despite having positive perceptions of exercise and PA during oncological treatment, there are significant barriers impacting participation. Lack of support from HCPs and fear of worsening symptoms were significant barriers. Future research should focus on impacting these barriers to ultimately improve PA and exercise levels in those undergoing oncological treatment.

Scoping review: Mobility aids for people with sight loss across the ICF domains of functions, activities, and participation.

SIGNIFICANCE: There is little literature linking mobility aids for people with sight loss to the functions, activities, and participation domains of the International Classification of Functioning, Disability and Health (ICF). Future studies on this relationship should be funded and pursued to better understand ways to maximize the benefit of mobility aids. PURPOSE: The ICF domains of functions, activities, and participation are potentially health-supporting aspects of daily living that may be impeded for people with sight loss. Although mobility aids facilitate safely navigating obstacles to optimize independence, it is not clear if they have any effect on functions, activities, or participation. This review explores the current literature to establish the associations between mobility aids and ICF domains. METHODS: An established scoping review methodological framework was used to systematically search, select, and synthesize the existing literature. RESULTS: Of 116 unique retrieved articles, three observational studies were eligible for inclusion with a total of 124 participants. A small experimental study found that blind adults had slower Timed Up and Go times than sighted and better performance with a long cane than without. One observational study found that physical activity was strongly related to level of visual acuity but with no independent impact of mobility aids. A single mixed-methods study explored travel frequency for blind people with assistance dogs and considered constraints to participation. CONCLUSIONS: Despite the included studies involving some aspect of mobility aid use by people with sight loss, to date, no study has focused exclusively on mobility aid intervention for people with sight loss within the physical function, physical activity, and participation domains of the ICF. There is no reliable evidence on the associations between mobility aids and physical function, physical activity, and participation. This is an important knowledge gap for determining the most suitable aids, as well as their use, to best facilitate health-supporting activities.

Efficacy of unsupervised exercise in adults with obstructive lung disease: a systematic review and meta-analysis.

INTRODUCTION: The benefits of unsupervised exercise programmes in obstructive lung disease are unclear. The aim of this systematic review was to synthesise evidence regarding the efficacy of unsupervised exercise versus non-exercise-based usual care in patients with obstructive lung disease. METHODS: Electronic databases (MEDLINE, CINAHL, Embase, Allied and Complementary Medicine Database, Web of Science, Cochrane Central Register of Controlled Trials and Physiotherapy Evidence Database) and trial registers (ClinicalTrials.gov, Current Controlled Trials, UK Clinical Trials Gateway and WHO International Clinical Trials Registry Platform) were searched from inception to April 2020 for randomised trials comparing unsupervised exercise programmes with non-exercise-based usual care in adults with chronic obstructive pulmonary disease (COPD), non-cystic fibrosis bronchiectasis or asthma. Primary outcomes were exercise capacity, quality of life, mortality, exacerbations and respiratory cause hospitalisations. RESULTS: Sixteen trials (13 COPD, 2 asthma, 1 chronic bronchitis: 1184 patients) met the inclusion criteria. Only data on COPD populations were available for meta-analysis. Unsupervised exercise resulted in a statistically but not clinically significant improvement in the 6-Minute Walk Test (n=5, MD=22.0 m, 95% CI 4.4 to 39.6 m, p=0.01). However, unsupervised exercise did lead to statistically significant and clinically meaningful improvements in St. George's Respiratory Questionnaire (n=4, MD=-11.8 points, 95% CI -21.2 to -2.3 points, p=0.01) and Chronic Respiratory Disease Questionnaire domains (dyspnoea: n=4, MD=0.5 points, 95% CI 0.1 to 0.8 points, p<0.01; fatigue: n=4, MD=0.7 points, 95% CI 0.4 to 1.0 points, p<0.01; emotion: n=4, MD=0.5 points, 95% CI 0.2 to 0.7 points, p<0.01; mastery: unable to perform meta-analysis) compared with non-exercise-based usual care. DISCUSSION: This review demonstrates clinical benefits of unsupervised exercise interventions on health-related quality of life in patients with COPD. High-quality randomised trials are needed to examine the effectiveness of prescription methods.

Development and Content Validity of the Clinical Assessment of Body Alignment for Children With Cerebral Palsy.

PURPOSE: The purpose of this study is to describe the development and content validity of the clinical assessment of body alignment (CABA) to measure body alignment in children with cerebral palsy. METHODS: Content validity and clinical utility were examined through expert opinion of 283 pediatric physical therapists. Participants reviewed items as matching or not to the domain of body alignment. Clinical utility was evaluated on a 5-point scale. Means and standard deviation were calculated for each attribute. Fleiss' kappa examined interrater reliability of expert responses. RESULTS: Percentage agreement was high for 19 items and good for 1 item. Clinicians' ratings showed overall fair to good agreement. Four clinical utility attributes had a net importance score of more than 90%, although interrater reliability was low. CONCLUSION: Content validity of the CABA was supported. Construct validity, reliability, and responsiveness require further study. What this adds to the evidence: The CABA has potential to offer clinicians and researchers a clinically practical measure of postural alignment for children with cerebral palsy. Preliminary investigation of CABA shows good content validity. However, more studies to assess the assessments' psychometrics including construct validity, reliability, and responsiveness are required.

Medical day hospital care for older people versus alternative forms of care.

BACKGROUND: The proportion of the world's population aged over 60 years is increasing. Therefore, there is a need to examine different methods of healthcare provision for this population. Medical day hospitals provide multidisciplinary health services to older people in one location. OBJECTIVES: To examine the effectiveness of medical day hospitals for older people in preventing death, disability, institutionalisation and improving subjective health status. SEARCH METHODS: Our search included the Cochrane Effective Practice and Organisation of Care (EPOC) Group Register of Studies, CENTRAL (2013, Issue 7), MEDLINE via Ovid (1950-2013 ), EMBASE via Ovid (1947-2013) and CINAHL via EbscoHost (1980-2013). We also conducted cited reference searches, searched conference proceedings and trial registries, hand searched select journals, and contacted relevant authors and researchers to inquire about additional data. SELECTION CRITERIA: Randomised and quasi-randomised trials comparing medical day hospitals with alternative care for older people (mean/median > 60 years of age). DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial eligibility and risk of bias and extracted data from included trials. We used standard methodological procedures expected by the Cochrane Collaboration. Trials were sub-categorised as comprehensive care, domiciliary care or no comprehensive care. MAIN RESULTS: Sixteen trials (3689 participants) compared day hospitals with comprehensive care (five trials), domiciliary care (seven trials) or no comprehensive care (four trials). Overall there was low quality evidence from these trials for the following results.For the outcome of death, there was no strong evidence for or against day hospitals compared to other treatments overall (odds ratio (OR) 1.05; 95% CI 0.85 to 1.28; P = 0.66), or to comprehensive care (OR 1.26; 95% CI 0.87 to 1.82; P = 0.22), domiciliary care (OR 0.97; 95% CI 0.61 to 1.55; P = 0.89), or no comprehensive care (OR 0.88; 95% CI 0.63 to 1.22; P = 0.43).For the outcome of death or deterioration in activities of daily living (ADL), there was no strong evidence for day hospital attendance compared to other treatments (OR 1.07; 95% CI 0.76 to 1.49; P = 0.70), or to comprehensive care (OR 1.18; 95% CI 0.63 to 2.18; P = 0.61), domiciliary care (OR 1.41; 95% CI 0.82 to 2.42; P = 0.21) or no comprehensive care (OR 0.76; 95% CI 0.56 to 1.05; P = 0.09).For the outcome of death or poor outcome (institutional care, dependency, deterioration in physical function), there was no strong evidence for day hospitals compared to other treatments (OR 0.92; 95% CI 0.74 to 1.15; P = 0.49), or compared to comprehensive care (OR 1.05; 95% CI 0.79 to 1.40; P = 0.74) or domiciliary care (OR 1.08; 95% CI 0.67 to 1.74; P = 0.75). However, compared with no comprehensive care there was a difference in favour of day hospitals (OR 0.72; 95% CI 0.53 to 0.99; P = 0.04).For the outcome of death or institutional care, there was no strong evidence for day hospitals compared to other treatments overall (OR 0.85; 95% CI 0.63 to 1.14; P = 0.28), or to comprehensive care (OR 1.00; 95% CI 0.69 to 1.44; P = 0.99), domiciliary care (OR 1.05; 95% CI 0.57 to1.92; P = 0. 88) or no comprehensive care (OR 0.63; 95% CI 0.40 to 1.00; P = 0.05).For the outcome of deterioration in ADL, there was no strong evidence that day hospital attendance had a different effect than other treatments overall (OR 1.11; 95% CI 0.68 to 1.80; P = 0.67) or compared with comprehensive care (OR 1.21; 0.58 to 2.52; P = 0.61), or domiciliary care (OR 1.59; 95% CI 0.87 to 2.90; P = 0.13). However, day hospital patients showed a reduced odds of deterioration compared with those receiving no comprehensive care (OR 0.61; 95% CI 0.38 to 0.97; P = 0.04) and significant subgroup differences (P = 0.04).For the outcome of requiring institutional care, there was no strong evidence for day hospitals compared to other treatments (OR 0.84; 95% CI 0.58 to 1.21; P = 0.35), or to comprehensive care (OR 0.91; 95% CI 0.70 to 1.19; P = 0.49), domiciliary care (OR 1.49; 95% CI 0.53 to 4.25; P = 0.45), or no comprehensive care (OR 0.58; 95% CI 0.28 to 1.20; P = 0.14). AUTHORS' CONCLUSIONS: There is low quality evidence that medical day hospitals appear effective compared to no comprehensive care for the combined outcome of death or poor outcome, and for deterioration in ADL. There is no clear evidence for other outcomes, or an advantage over other medical care provision.

Patient Decision Aids for Aortic Stenosis and Chronic Coronary Artery Disease: A Systematic Review and Meta-Analysis.

AIM: Shared decision-making is recommended for patients considering treatment options for severe aortic stenosis (AS) and chronic coronary artery disease (CAD). This review aims to systematically identify and assess patient decision aids (PtDAs) for chronic CAD and AS and evaluate the international evidence on their effectiveness for improving the quality of decision-making. METHODS AND RESULTS: Five databases (Cochrane, CINAHL, Embase, MEDLINE, PsycInfo), clinical trial registers and 30 PtDA repositories/websites were searched from 2006 to March 2023. Screening, data extraction and quality assessments were completed independently by multiple reviewers. Meta-analyses were conducted using Stata statistical software. Eleven AS and 10 CAD PtDAs were identified; seven were less than five years old. Over half the PtDAs were web-based and the remainder paper-based. One AS and two CAD PtDAs fully/partially achieved international PtDA quality criteria. Ten studies were included in the review; four reported on the development/evaluation of AS PtDAs and six on CAD PtDAs. Most studies were conducted in the USA with White, well-educated, English-speaking participants. No studies fulfilled all quality criteria for reporting PtDA development and evaluation. Meta-analyses found that PtDAs significantly increased patient knowledge compared to 'usual care' (mean difference:0.620; 95%CI 0.396, 0.845, p < 0.001) but did not change decisional conflict. CONCLUSION: Patients who use PtDAs when considering treatments for AS or chronic CAD are likely to be better informed than those who do not. Existing PtDAs may not meet the needs of people with low health literacy levels as they are rarely involved in their development.

An investigation into the hypoalgesic effects of transcutaneous piezoelectric current on experimentally induced thermal stimuli in healthy participants.

OBJECTIVES: To investigate the effects of transcutaneous piezoelectric currents on experimentally induced thermal pain in healthy human participants. MATERIALS AND METHODS: A repeated measure cross-over study recorded sensory detection and pain thresholds to contact thermal stimuli during active and placebo (no current) transcutaneous piezoelectric current in 15 pain-free healthy human volunteers. Active transcutaneous piezoelectric current (6 µA) was delivered as 35 high voltage single rectangular pulses (1 Hz) at the LI4 (Hegu) acupuncture point. RESULTS: Repeated measures ANOVA found that active and placebo transcutaneous piezoelectric current elevated thresholds for warm sensation, heat pain, and cold sensation. However, there were no statistically significant effects for active piezoelectric current compared with placebo for any outcome measure. CONCLUSIONS: Reductions in experimentally induced pain were not due to piezoelectric currents per se. These findings challenge claims about the efficacy of transcutaneous piezoelectric currents for pain relief. A clinical trial is needed.

An experimental study on the self-report of acupuncture needle sensation during deep needling with bi-directional rotation.

BACKGROUND: Traditionally, acupuncturists manipulate needles to enhance sensations referred to as de qi or 'acupuncture needle sensation'. Acupuncture needle sensations are complex and quantifying the experience has been difficult. The aim of this crossover study was to measure self-reported needle sensation during deep and bi-directional rotated needling in 15 healthy volunteers. METHODS: Each participant received an experimental intervention consisting of superficial needling followed by deep needling and then deep needling with bi-directional rotation. The control intervention consisted of superficial needling, followed by mock deep needling and then mock bi-directional rotation of the needle. The intensity of overall needle sensation was measured using a visual analogue scale (VAS). The subjective acupuncture sensation scale was used to capture component sensations. RESULTS: VAS scores were higher during 'deep' needle penetration when compared to superficial needling with mock deep insertion (p=0.0002). VAS scores were also higher during deep needling with bi-directional rotation compared to superficial needling with mock bi-directional rotation (p<0.0001). There were higher scores for total component sensation scores and for the sensation of throbbing during the deep needling with bi-directional rotation (p=0.001) when compared to superficial needling with mock bi-directional rotation. Tentative evidence that bi-directional needle rotation generated stabbing, tingling, heaviness, soreness and aching was also found. CONCLUSION: Bi-directional rotation of a needle inserted into deep soft tissue produced higher acupuncture needle sensation intensities when compared to superficial needle insertion with mock deep penetration and bi-directional rotation.

Reflections on mirror therapy: a systematic review of the effect of mirror visual feedback on the brain.

BACKGROUND: Mirror visual feedback (MVF), a phenomenon where movement of one limb is perceived as movement of the other limb, has the capacity to alleviate phantom limb pain or promote motor recovery of the upper limbs after stroke. The tool has received great interest from health professionals; however, a clear understanding of the mechanisms underlying the neural recovery owing to MVF is lacking. OBJECTIVE: We performed a systematic review to assess the effect of MVF on brain activation during a motor task. METHODS: We searched PubMed, CINAHL, and EMBASE databases for neuroimaging studies investigating the effect of MVF on the brain. Key details for each study regarding participants, imaging methods, and results were extracted. RESULTS: The database search yielded 347 article, of which we identified 33 suitable for inclusion. Compared with a control condition, MVF increases neural activity in areas involved with allocation of attention and cognitive control (dorsolateral prefrontal cortex, posterior cingulate cortex, S1 and S2, precuneus). Apart from activation in the superior temporal gyrus and premotor cortex, there is little evidence that MVF activates the mirror neuron system. MVF increases the excitability of the ipsilateral primary motor cortex (M1) that projects to the "untrained" hand/arm. There is also evidence for ipsilateral projections from the contralateral M1 to the untrained/affected hand as a consequence of training with MVF. CONCLUSION: MVF can exert a strong influence on the motor network, mainly through increased cognitive penetration in action control, though the variance in methodology and the lack of studies that shed light on the functional connectivity between areas still limit insight into the actual underlying mechanisms.

Effect of bidirectional rotation of an acupuncture needle at LI10 on acupuncture needle sensation and experimentally-induced contact heat pain in healthy human volunteers.

INTRODUCTION: There is insufficient evidence of a relationship between acupuncture needle sensations (de qi) and hypoalgesia. The aim of this study was to investigate the effects of bidirectional needle rotation at LI10 on acupuncture needle sensations and heat pain thresholds. METHODS: Twenty-two healthy participants received one acupuncture needle at LI10 with bidirectional rotation of the needle in one experimental session and one acupuncture needle at LI10 with mock rotation in a separate session, in a randomised order. Measurements of heat pain thresholds were taken before needle insertion, during needle retention and 15 min after needle removal. At each measurement time point, participants rated needle sensations using the Massachusetts Acupuncture Sensation Scale (MASS) and a visual analogue scale (VAS) of overall intensity of needle sensation. RESULTS: Bidirectional needle rotation produced significantly higher scores for VAS, MASStotal, MASSpain and MASSsensation compared with mock rotation (all p<0.001). There were significantly higher pain thresholds relative to pre-intervention baseline during (p=0.014) and after (p<0.001) bidirectional needle rotation but not during (p=0.1) or after (p=0.62) mock bidirectional needle rotation. Bidirectional needle rotation increased the pain threshold relative to baseline 15 min after the needles were removed (p=0.009). A significant but low correlation between needle sensation and change in pain threshold after needling was only found when data from mock and rotation interventions were combined. CONCLUSIONS: Needle rotation increases the magnitude of hypoalgesia. There is tentative evidence that needle sensation may be associated with the amount of change in pain threshold.

Intra-individual variations in the bifurcation of the radial nerve and the length of the posterior interosseous nerve.

Anatomical literature on the radial nerve predominantly features inter-individual variations, with comparatively few studies investigating intra-individual variations. The radial nerve has a complex and variable course, particularly in relation to the location at which the nerve bifurcates to form the superficial branch of the radial nerve and the posterior interosseous nerve. Variations of the radial nerve may change the way the nerve and its branches, their blood supply and nerve transmission respond to forces. This study investigated the presence of intra-individual differences in the bifurcation point of the radial nerve and the length of the posterior interosseous nerve from the bifurcation to the radial tunnel. Eighteen embalmed human cadavers were dissected to reveal the radial nerve. Measurements were taken from the level of the lateral humeral epicondyle to the bifurcation of the radial nerve, and from the bifurcation to the radial tunnel. All cadavers presented with intra-individual variations between the left and right limbs. Significant differences were found between the left and right limbs for the measurement from the lateral humeral epicondyle to the bifurcation (median difference = 18.0 mm; p = 0.016) but not for the measurement from the bifurcation to the radial tunnel (median difference = 7.0 mm; p = 0.396). In conclusion, the location of the radial nerve bifurcation is subject to both intra- and inter-individual variations. Its specific relationship to the lateral humeral epicondyle also varies, occurring both distal and proximal to the level of the epicondyle. Clinical implications of these findings warrant further investigation.

Could acupuncture needle sensation be a predictor of analgesic response?

During acupuncture some patients experience distinct sensations which are often referred to as needle sensation. Needle sensation may be related to treatment outcome, although what constitutes adequate acupuncture needle sensation is not known. In this paper, we debate the possibility of using the self-report of the overall intensity of needle sensation as a predictor of analgesic outcome to acupuncture. We describe how our approach to establish criteria to determine adequacy of transcutaneous electrical nerve stimulation interventions in clinical trials has been used to inform our search for markers of adequacy of procedural technique for acupuncture. We describe previous research which has focused on developing tools to capture the nature of the descriptors used by patients when they self-report needle sensation and reveal that little attention has been given to its role in outcome. We demonstrate that needle sensation is a complex phenomenon with subjects using multiple descriptors to report their experience. We argue that the intensity of the overall experience of needle sensation may prove useful as a gross marker of the adequacy of acupuncture. We briefly describe our research which isolates individual components of needling technique, such as depth of needle penetration and bidirectional needle rotation, in order to assess their contribution to overall needle sensation intensity.
