RESUMO
BACKGROUND AND AIMS: Uncertainty exists over whether multiple arterial grafting has a sex-related association with survival after coronary artery bypass grafting. This study aims to compare the long-term survival of using multiple arterial grafting vs. single arterial grafting in women and men undergoing coronary artery bypass grafting. METHODS: The retrospective study used the Australian and New Zealand Society of Cardiothoracic Surgical Database with linkage to the National Death Index. Patients from 2001 to 2020 were identified. Sex-stratified, inverse probability weighted Cox proportional hazard model was used to facilitate survival comparisons. The primary outcome was all-cause mortality. RESULTS: A total number of 54 275 adult patients receiving at least two grafts in primary isolated bypass operations were analysed. The entire study cohort consisted of 10 693 (19.7%) female patients and 29 711 (54.7%) multiple arterial grafting procedures. At a median (interquartile range) postoperative follow-up of 4.9 (2.3-8.4) years, mortality was significantly lower in male patients undergoing multiarterial than single arterial procedures (adjusted hazard ratio 0.82; 95% confidence interval 0.77-0.87; P < .001). The survival benefit was also significant for females (adjusted hazard ratio 0.83; 95% confidence interval 0.76-0.91; P < .001) at a median (interquartile range) follow-up of 5.2 (2.4-8.7) years. The interaction model from Cox regression suggested insignificant subgroup effect from sex (P = .08) on the observed survival advantage. The survival benefits associated with multiple arterial grafting were consistent across all sex-stratified subgroups except for female patients with left main coronary disease. CONCLUSIONS: Compared to single arterial grafting, multiple arterial revascularization is associated with improved long-term survival for women as well as men.

OBJECTIVE: To review the effectiveness of different physical therapies for acute and sub-acute low back pain supported by evidence, and create clinical recommendations and expert consensus for physiotherapists on clinical prescriptions. DATA SOURCES: A systematic search was conducted in PubMed and the Cochrane Library for studies published within the previous 15 years. REVIEW METHODS: Systematic review and meta-analysis, randomized controlled trials assessing patients with acute and sub-acute low back pain were included. Two reviewers independently screened relevant studies using the same inclusion criteria. The Physiotherapy Evidence Database and the Assessment of Multiple Systematic Reviews tool were used to grade the quality assessment of randomized controlled trials and systematic reviews, respectively. The final recommendation grades were based on the consensus discussion results of the Delphi of 22 international experts. RESULTS: Twenty-one systematic reviews and 21 randomized controlled trials were included. Spinal manipulative therapy and low-level laser therapy are recommended for acute low back pain. Core stability exercise/motor control, spinal manipulative therapy, and massage can be used to treat sub-acute low back pain. CONCLUSIONS: The consensus statements provided medical staff with appliable recommendations of physical therapy for acute and sub-acute low back pain. This consensus statement will require regular updates after 5-10 years.

OBJECTIVE: Significant variations exist in the use of respiratory muscle ultrasound in intensive care with no society-level consensus on the optimal methodology. This systematic review aims to evaluate, synthesize, and compare the clinimetric properties of different image acquisition and analysis methodologies. DATA SOURCES: Systematic search of five databases up to November 24, 2021. STUDY SELECTION: Studies were included if they enrolled at least 50 adult ICU patients, reported respiratory muscle (diaphragm or intercostal) ultrasound measuring either echotexture, muscle thickness, thickening fraction, or excursion, and evaluated at least one clinimetric property. Two independent reviewers assessed titles, abstracts, and full text against eligibility. DATA EXTRACTION: Study demographics, ultrasound methodologies, and clinimetric data. DATA SYNTHESIS: Sixty studies, including 5,025 patients, were included with 39 studies contributing to meta-analyses. Most commonly measured was diaphragm thickness (DT) or diaphragm thickening fraction (DTF) using a linear transducer in B-mode, or diaphragm excursion (DE) using a curvilinear transducer in M-mode. There are significant variations in imaging methodology and acquisition across all studies. Inter- and intrarater measurement reliabilities were generally excellent, with the highest reliability reported for DT (ICC, 0.98; 95% CI, 0.94-0.99). Pooled data demonstrated acceptable to excellent accuracy for DT, DTF, and DE to predicting weaning outcome after 48 to 72 hours postextubation (DTF AUC, 0.79; 95% CI, 0.73-0.85). DT imaging was responsive to change over time. Only three eligible studies were available for intercostal muscles. Intercostal thickening fraction was shown to have excellent accuracy of predicting weaning outcome after 48-hour postextubation (AUC, 0.84; 95% CI, 0.78-0.91). CONCLUSIONS: Diaphragm muscle ultrasound is reliable, valid, and responsive in ICU patients, but significant variation exists in the imaging acquisition and analysis methodologies. Future work should focus on developing standardized protocols for ultrasound imaging and consider further research into the role of intercostal muscle imaging.

Traditional risk factors used for predicting poor postoperative recovery have focused on postoperative complications, adverse symptoms (nausea, pain), length of hospital stay, and patient quality of life. Despite these being traditional performance indicators of patient postoperative "status," they may not fully define the multidimensional nature of patient recovery. The definition of postoperative recovery is thus evolving to include patient-reported outcomes that are important to the patient. Previous reviews have focused on risk factors for the above traditional outcomes after major surgery. Yet, there remains a need for further study of risk factors predicting multidimensional patient-focused recovery, and investigation beyond the immediate postoperative period after patients are discharged from the hospital. This review aimed to appraise the current literature identifying risk factors for multidimensional patient recovery. METHODS: A systematic review without meta-analysis was performed to qualitatively summarize preoperative risk factors for multidimensional recovery 4-6 weeks after major surgery (PROSPERO, CRD42022321626). We reviewed three electronic databases between January 2012 and April 2022. The primary outcome was risk factors for multidimensional recovery at 4-6 weeks. A GRADE quality appraisal and a risk of bias assessment were completed. RESULTS: In total, 5150 studies were identified, after which 1506 duplicates were removed. After the primary and secondary screening, nine articles were included in the final review. Interrater agreements between the two assessors for the primary and secondary screening process were 86% (k = 0.47) and 94% (k = 0.70), respectively. Factors associated with poor recovery were found to include ASA grade, recovery tool baseline score, physical function, number of co-morbidities, previous surgery, and psychological well-being. Mixed results were reported for age, BMI, and preoperative pain. Due to the observational nature, heterogeneity, multiple definitions of recovery, and moderate risk of bias of the primary studies, the quality of evidence was rated from very low to low. CONCLUSION: Our review found that there were few studies assessing preoperative risk factors as predictors for poor postoperative multidimensional recovery. This confirms the need for higher quality studies assessing risk for poor recovery, ideally with a consistent and multi-dimensional definition of recovery.
RESUMO
The ability of the lumbar extensor muscles to accurately control static and dynamic forces is important during daily activities such as lifting. Lumbar extensor force control is impaired in low-back pain patients and may therefore explain the variances in lifting kinematics. Thirty-three chronic low-back pain participants were instructed to lift weight using a self-selected technique. Participants also performed an isometric lumbar extension task where they increased and decreased their lumbar extensor force output to match a variable target force within 20-50% lumbar extensor maximal voluntary contraction. Lifting trunk and lower limb range of motion and angular velocity variables derived from phase plane analysis in all planes were calculated. Lumbar extensor force control was analyzed by calculating the Root-Mean-Square Error (RMSE) between the participants' force and the target force during the increasing (RMSEA), decreasing (RMSED) force portions and for the overall force error (RMSET) of the test. The relationship between lifting kinematics and RMSE variables was analyzed using multiple linear regression. Knee angular velocity in the sagittal and coronal planes were positively associated with RMSEA (R2 = 0.10, ß = 0.35, p = 0.046 and R2 = 0.21, ß = 0.48, p = 0.004, respectively). Impaired lumbar extensor force control is associated with increased multiplanar knee movement velocity during lifting. The study findings suggest a potential relationship between lumbar and lower limb neuromuscular function in people with chronic low-back pain.

BACKGROUND: The COVID-19 pandemic has accelerated the demand for utilising telehealth as a major mode of healthcare delivery, with increasing interest in the use of tele-platforms for remote patient assessment. In this context, the use of smartphone technology to measure squat performance in people with and without femoroacetabular impingement (FAI) syndrome has not been reported yet. We developed a novel smartphone application, the TelePhysio app, which allows the clinician to remotely connect to the patient's device and measure their squat performance in real time using the smartphone inertial sensors. The aim of this study was to investigate the association and test-retest reliability of the TelePhysio app in measuring postural sway performance during a double-leg (DLS) and single-leg (SLS) squat task. In addition, the study investigated the ability of TelePhysio to detect differences in DLS and SLS performance between people with FAI and without hip pain. METHODS: A total of 30 healthy (nfemales = 12) young adults and 10 adults (nfemales = 2) with diagnosed FAI syndrome participated in the study. Healthy participants performed DLS and SLS on force plates in our laboratory, and remotely in their homes using the TelePhysio smartphone application. Sway measurements were compared using the centre of pressure (CoP) and smartphone inertial sensor data. A total of 10 participants with FAI (nfemales = 2) performed the squat assessments remotely. Four sway measurements in each axis (x, y, and z) were computed from the TelePhysio inertial sensors: (1) average acceleration magnitude from the mean (aam), (2) root-mean-square acceleration (rms), (3) range acceleration (r), and (4) approximate entropy (apen), with lower values indicating that the movement is more regular, repetitive, and predictable. Differences in TelePhysio squat sway data were compared between DLS and SLS, and between healthy and FAI adults, using analysis of variance with significance set at 0.05. RESULTS: The TelePhysio aam measurements on the x- and y-axes had significant large correlations with the CoP measurements (r = 0.56 and r = 0.71, respectively). The TelePhysio aam measurements demonstrated moderate to substantial between-session reliability values of 0.73 (95% CI 0.62-0.81), 0.85 (95% CI 0.79-0.91), and 0.73 (95% CI 0.62-0.82) for aamx, aamy, and aamz, respectively. The DLS of the FAI participants showed significantly lower aam and apen values in the medio-lateral direction compared to the healthy DLS, healthy SLS, and FAI SLS groups (aam = 0.13, 0.19, 0.29, and 0.29, respectively; and apen = 0.33, 0.45, 0.52, and 0.48, respectively). In the anterior-posterior direction, healthy DLS showed significantly greater aam values compared to the healthy SLS, FAI DLS, and FAI SLS groups (1.26, 0.61, 0.68, and 0.35, respectively). CONCLUSIONS: The TelePhysio app is a valid and reliable method of measuring postural control during DLS and SLS tasks. The application is capable of distinguishing performance levels between DLS and SLS tasks, and between healthy and FAI young adults. The DLS task is sufficient to distinguish the level of performance between healthy and FAI adults. This study validates the use of smartphone technology as a tele-assessment clinical tool for remote squat assessment.

This prospective study aimed to determine which specific mobility tests were the most accurate for predicting falls in physically active older adults living in the community. Seventy-nine physically active older adults who met the American College of Sports Medicine physical activity guidelines volunteered. Participants were assessed and followed up for 12 months. Mobility assessments included the 30-s sit-to-stand test, five times sit-to-stand test, single-task timed-up-and-go test (TUG), motor dual-task TUG (Mot-TUG), and cognitive dual-task TUG (Cog-TUG). Mot-TUG and Cog-TUG performances were moderately correlated with number of falls (r = .359, p < .01 and r = .372, p < .01, respectively). When Mot-TUG, Cog-TUG, or Age were included as fall predictors, discrimination scores represented by the area under the receiver operating characteristic curve (AUC) were AUC (Mot-TUG) = 0.843 (p < .01), AUC (Cog-TUG) = 0.856 (p < .01), and AUC (Age) = 0.734 (p < .05). The cutoff point for Cog-TUG was 10.98 s, with test sensitivity of 1.00 and specificity of 0.66. Fall predictors for different populations may be based on different test methods. Here, the dual-task TUG test more accurately predicted falls in older adults who met American College of Sports Medicine's physical activity guidelines.

PURPOSE: The objective of this study was to compare the effects of 12 weeks of resistance training combined with either 5:2 intermittent fasting or continuous energy restriction on body composition, muscle size and quality, and upper and lower body strength. METHODS: Untrained individuals undertook 12 weeks of resistance training plus either continuous energy restriction [20% daily energy restriction (CERT)] or 5:2 intermittent fasting [~ 70% energy restriction 2 days/week, euenergetic consumption 5 days/week (IFT)], with both groups prescribed a mean of ≥ 1.4 g of protein per kilogram of body weight per day. Participants completed 2 supervised resistance and 1 unsupervised aerobic/resistance training combination session per week. Changes in lean body mass (LBM), thigh muscle size and quality, strength and dietary intake were assessed. RESULTS: Thirty-four participants completed the study (CERT = 17, IFT = 17). LBM was significantly increased (+ 3.7%, p < 0.001) and body weight (- 4.6%, p < 0.001) and fat (- 24.1%, p < 0.001) were significantly reduced with no significant difference between groups, though results differed by sex. Both groups showed improvements in thigh muscle size and quality, and reduced intramuscular and subcutaneous fat assessed by ultrasonography and peripheral quantitative computed tomography (pQCT), respectively. The CERT group demonstrated a significant increase in muscle surface area assessed by pQCT compared to the IFT group. Similar gains in upper and lower body strength and muscular endurance were observed between groups. CONCLUSION: When combined with resistance training and moderate protein intake, continuous energy restriction and 5:2 intermittent fasting resulted in similar improvements in body composition, muscle quality, and strength. ACTRN: ACTRN12620000920998, September 2020, retrospectively registered.

BACKGROUND: Tele-health has become a major mode of delivery in patient care, with increasing interest in the use of tele-platforms for remote patient assessment. The use of smartphone technology to measure hip range of motion has been reported previously, with good to excellent validity and reliability. However, these smartphone applications did not provide real-time tele-assessment functionality. We developed a novel smartphone application, the TelePhysio app, which allows the clinician to remotely connect to the patient's device and measure their hip range of motion in real time. The aim of this study was to investigate the concurrent validity and between-sessions reliability of the TelePhysio app. In addition, the study investigated the concurrent validity, between-sessions, and inter-rater reliability of a second tele-assessment approach using video analysis. METHODS: Fifteen participants (nfemales = 6) were assessed in our laboratory (session 1) and at their home (session 2). We assessed maximum voluntary active hip flexion in supine and hip internal and external rotation, in both prone and sitting positions. TelePhysio and video analysis were validated against the laboratory's 3-dimensional motion capture system in session 1, and evaluated for between-sessions reliability in session 2. Video analysis inter-rater reliability was assessed by comparing the analysis of two raters in session 2. RESULTS: The TelePhysio app demonstrated high concurrent validity against the 3D motion capture system (ICCs 0.63-0.83) for all hip movements in all positions, with the exception of hip internal rotation in prone (ICC = 0.48, p = 0.99). The video analysis demonstrated almost perfect concurrent validity against the 3D motion capture system (ICCs 0.85-0.94) for all hip movements in all positions, with the exception of hip internal rotation in prone (ICC = 0.44, p = 0.01). The TelePhysio and video analysis demonstrated good between-sessions reliability for hip external rotation and hip flexion, ICC 0.64 and 0.62, respectively. The between-sessions reliability of hip internal and external rotation for both TelePhysio and video analysis was fair (ICCs 0.36-0.63). Inter-rater reliability ICCs for the video analysis were 0.59 for hip flexion and 0.87-0.95 for the hip rotation range. CONCLUSIONS: Both tele-assessment approaches, using either a smartphone application or video analysis, demonstrate good to excellent concurrent validity, and moderate to substantial between-sessions reliability in measuring hip rotation and flexion range of motion, but less in internal hip rotation in the prone position. Thus, it is recommended that the seated position be used when assessing hip internal rotation. The use of a smartphone to remotely assess hip range of motion is an appropriate, effective, and low-cost alternative to the face-to-face assessments. This method provides a simple, cost effective, and accessible patient assessment tool with no additional cost. This study validates the use of smartphone technology as a tele-assessment tool for remote hip range of motion assessment.

AIMS: To investigate the effects of a 12-week early moderate-intensity resistance training program compared to aerobic-based rehabilitation on postoperative cognitive recovery following cardiac surgery via median sternotomy. METHODS: This was a multicentre, prospective, pragmatic, non-blinded, pilot randomised controlled trial (1:1 randomisation) of two parallel groups that compared a 12-week early moderate-intensity resistance training group to a control group, receiving aerobic-based rehabilitation. English-speaking adults (≥18 years) undergoing elective cardiac surgery via median sternotomy were randomised using sealed envelopes, with allocation revealed before surgery. The primary outcome was cognitive function, assessed using the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog), at baseline, 14 weeks and 6 months postoperatively. RESULTS: The ADAS-cog score at 14 weeks was significantly better for the resistance training group (n=14, 7.2±1.4; 95% CI 4.3, 10.2, vs n=17, 9.2±1.3; 95% CI 6.6, 11.9, p=0.010). At 14 weeks postoperatively, 53% of the aerobic-based rehabilitation group (n=9/17) experienced cognitive decline by two points or more from baseline ADAS-cog score, compared to 0% of the resistance training group (n=0/14; p=0.001). CONCLUSION: Early resistance training appears to be safe and may improve cognitive recovery compared to standard, aerobic-based rehabilitation following cardiac surgery via median sternotomy, however as this was a pilot study, the sample size was small and further research is needed to determine a causal relationship.

BACKGROUND: Neck pain is common in dancers, especially female dancers, and the injury pattern varies in different genres of dance. Among dancesport performers, intensive neck left rotation is required in female International Standard dancers, but it is unknown whether neck pain is associated with neck rotation range of motion and proprioception. OBJECTIVES: To explore the associations between neck pain, cervical rotation range of motion, and proprioception in female International Standard dancers. METHODS: Twelve dancers with dance-related neck pain (age 19.9±1.9 yrs) volunteered, matched with 12 not reporting neck pain (age 22.2±2.4 yrs). A 100-mm visual analog scale (VAS) was used to record neck pain. Active rotation range of motion (AROM) of the cervical spine was measured using a tape measure. A cervical rotation reposition test that used a head-mounted laser projector on a linear scale was employed to measure the cervical spine proprioception, and the absolute error (AE) and variable error (VE) were calculated as proprioceptive acuity scores. RESULTS: Nine of 12 participants in the group with neck pain declared left side pain, with 2 reporting pain on both sides. The group with neck pain had significantly lower left rotation AROM (p<0.05). For proprioceptive acuity, mixed model ANOVA only showed that repositioning of the right side of the neck is more accurate and consistent than that of the left (both AE and VE p<0.05). Linear regression analysis indicated that left rotation AROM was significantly influenced by left neck pain (t=3.061, p=0.006, adjusted R2 = 0.267, and Durbin-Watson value = 1.776). CONCLUSIONS: Most participants in the group with neck pain showed left side pain, associated with decreased left rotation AROM. Early screening on cervical rotation mobility may be necessary to reduce future dance-related injury after the onset of neck pain. Proprioceptive acuity of the left side neck was significantly impaired compared with that of the right, indicating future proprioceptive intervention on the left side neck.

Quadriceps atrophy and morphological change is a known phenomenon that can impact significantly on strength and functional performance in patients with acute or chronic presentations conditions. Real-time ultrasound (RTUS) imaging is a noninvasive valid and reliable method of quantifying quadriceps muscle anatomy and architecture. To date, there is a paucity of normative data on the architectural properties of superficial and deep components of the quadriceps muscle group to inform assessment and evaluation of intervention programs. The aims of this study were to (1) quantify the anatomical architectural properties of the quadriceps muscle group (rectus femoris, vastus intermedius, and vastus lateralis) using RTUS in healthy older adults and (2) to determine the relationship between RTUS muscle parameters and measures of quadriceps muscle strength. Thirty middle aged to older males and females (age range 55-79 years; mean age =59.9 ± 7.08 years) were recruited. Quadriceps muscle thickness, cross-sectional area, pennation angle, and echogenicity were measured using RTUS. Quadriceps strength was measured using hand-held dynamometry. For the RTUS-derived quadriceps morphological data, rectus femoris mean results; circumference 9.3 cm; CSA 4.6 cm2 ; thickness 1.5 cm; echogenicity 100.2 pixels. Vastus intermedius mean results; thickness 1.8 cm; echogenicity 99.1 pixels. Vastus lateralis thickness 1.9 cm; pennation angle 17.3°; fascicle length 7.0 cm. Quadriceps force was significantly correlated only with rectus femoris circumference (r = 0.48, p = 0.007), RF echogenicity (r = 0.38, p = 0.037), VI echogenicity (r = 0.43, p = 0.018), and VL fascicle length (r = 0.43, p = 0.019). Quadriceps force was best predicted by a three-variable model (adjusted R2 = 0.46, p < 0.001) which included rectus femoris echogenicity (B = 0.43, p = 0.005), vastus lateralis fascicle length (B = 0.33, p = 0.025) and rectus femoris circumference (B = 0.31, p = 0.041). Thus respectively, rectus femoris echogenicity explains 43%, vastus lateralis fascicle length explains 33% and rectus femoris circumference explains 31% of the variance of quadriceps force. The study findings suggest that RTUS measures were reliable and further research is warranted to establish whether these could be used as surrogate measures for quadriceps strength in adults to inform exercise and rehabilitation programs.

OBJECTIVES: To investigate the specific clinical features of pain following cardiac surgery and evaluate the information derived from different pain measurement tools used to quantify and describe pain in this population. METHODS: A prospective observational study was undertaken at two tertiary care hospitals in Australia. Seventy-two (72) adults (mean age, 63±11 years) were included following cardiac surgery via a median sternotomy. Participants completed the Patient Identified Cardiac Pain using numeric and visual prompts (PICP), the McGill Pain Questionnaire-Short Form version 2 (MPQ-2) and the Medical Outcome Study 36-item version 2 (SF-36v2) Bodily Pain domain (BP), which were administered prior to hospital discharge, 4 weeks and 3 months postoperatively. RESULTS: Participants experienced a high incidence of mild (n=45, 63%) to moderate (n=22, 31%) pain prior to discharge, which reduced at 4 weeks postoperatively: mild (n=28, 41%) and moderate (n=5, 7%) pain; at 3 months participants reported mild (n=14, 20%) and moderate (n=2, 3%) pain. The most frequent location of pain was the anterior chest wall, consistent with the location of the surgical incision and graft harvest. Most participants equated "pressure/weight" to "aching" or a "heaviness" in the chest region (based on descriptor of pain in the PICP) and the pain topography was persistent at 4 weeks and 3 months postoperatively. Each pain measurement tool provided different information on pain location, severity and description, with significant change (p<0.005) over time. CONCLUSION: Mild-to-moderate pain was frequent after sternotomy, improved over time and was mostly located over the incision and mammary (internal thoracic) artery harvest site. Persistent pain at 3 months remained a significant problem in the community within this surgical population.

BACKGROUND: The MacNew heart disease health related quality of life tool is used widely in the cardiac populations to evaluate the impact of disease and intervention including rehabilitation. In addition to the English version, it is also available for several other languages except the Indonesian language. Therefore, the purpose of this study were 1) to translate the MacNew questionnaire from the English version to the Indonesian language and 2) to estimate the preliminary validity and reliability of the Indonesian MacNew for patients with coronary artery disease. METHODS: Forward and backward translation procedure was used to develop the Indonesian MacNew. The Indonesian MacNew was administered to 24 patients after one week of revascularization surgery. Reliability was assessed by internal consistency and test-retest reliability. To evaluate concurrent validity, the correlation of the compatible domain of the Indonesian MacNew and SF-36 was assessed. RESULTS: Internal consistency reliability of the Indonesian MacNew was confirmed with Cronbach's α of the global scale and all three subscales exceeding 0.95. Test- retest reliability was acceptable with intraclass correlation coefficient of 0.66 for the global score. Furthermore, an acceptable concurrent validity was established with statistically significant correlation between Indonesian MacNew and SF-36 (pearson correlation ranging from 0.47 to 0.71). CONCLUSION: The first results of the Indonesian MacNew indicate acceptable validity and reliability as a measurement tool to assess health related quality of life of Indonesian patients with coronary artery disease.

OBJECTIVE: The aim of this study was to investigate the psychometric properties of the shortened version of the Functional Difficulties Questionnaire (FDQ). DESIGN: This is a multisite observational study. SETTING: The study was conducted in four tertiary care hospitals in Australia. SUBJECTS: A total of 225 participants, following cardiac surgery, were involved in the study. INTERVENTION: Participants completed the original 13-item FDQ and other measures of physical function, pain and health-related quality of life. METHOD: Item reduction was utilized to develop the shortened version. Reliability was evaluated using intraclass correlation coefficients (ICCs), the smallest detectable change and Bland-Altman plots. The validity and responsiveness were evaluated using correlation. Anchor and distribution-based calculation was used to calculate the minimal clinical important difference (MCID). RESULTS: Item reduction resulted in the creation of a 10-item shortened version of the questionnaire (FDQ-s). Within the cohort of cardiac surgery patient, the mean (SD) for the FDQ-s was 38.7 (19.61) at baseline; 15.5 (14.01) at four weeks and 7.9 (12.01) at three months. Validity: excellent internal consistency (Cronbach's α > 0.90) and fair-to-excellent construct validity (>0.4). Reliability: internal consistency was excellent (Cronbach's α > 0.8). The FDQ-s had excellent test-retest reliability (ICC = 0.89-0.92). Strong responsiveness overtime was demonstrated with large effect sizes (Cohen's d > 1.0). The MCID of the FDQ-s was calculated between 4 and 10 out of 100 (in cm). CONCLUSION: The FDQ-s demonstrated robust psychometric properties as a measurement tool of physical function of the thoracic region following cardiac surgery.

BACKGROUND: Despite a paucity of evidence, patients following cardiac surgery via median sternotomy are routinely prescribed sternal precautions that restrict upper limb and trunk movements, with the rationale of reducing postoperative sternal complications such as sternal wound dehiscence, instability, infection and/or pain. The primary aim of this study was to measure motion at the sternal edges during dynamic upper limb and trunk tasks to better inform future sternal precautions and optimise postoperative recovery. Motion at the sternal edges was measured using ultrasound, which has been demonstrated to be a clinically valid and reliable measure in patients following cardiac surgery. METHODS: Seventy-five (75) patients following cardiac surgery via median sternotomy with conventional stainless steel wire closure were recruited. Motion at the sternal edges in the lateral (coronal plane) and anterior-posterior (sagittal plane) directions was measured at the level of the fourth intercostal space (mid-sternum) using ultrasound. Ultrasound measures were taken at rest and during five dynamic upper limb and trunk tasks (deep inspiration, cough, unilateral and bilateral upper limb elevation and sit to stand), over the first 3 postoperative months (3 to 7 days, 6 weeks and 3 months postoperatively). Sternal pain, functional status and sternal healing were also observed over the same postoperative period. RESULTS: The magnitude of overlap of the sternal edges in the lateral direction, and separation of the sternal edges in the anterior-posterior direction, both significantly decreased by 0.01cm, over the first 3 postoperative months (p<0.01). Coughing, however, produced a significant increase in separation of the sternal edges in the lateral direction (0.01-0.02cm) and pain (12-63%), compared to rest and all other tasks, at each postoperative time point (p<0.01). Additionally, there was a significant decrease in sternal pain (81%) and increase in postoperative function (79%) over the same postoperative period (p<0.01). At 3 months postoperatively, five (7%) participants demonstrated radiological sternal union and one (1%) participant was diagnosed with clinical sternal instability. CONCLUSIONS: A small magnitude of multi-planar motion at the sternal edges, at the mid-sternum, was demonstrated during dynamic upper limb and trunk tasks in a cohort of cardiac surgery patients post-sternotomy, over the first 3 postoperative months. Future research investigating motion at different levels of the sternum, with varying methods of sternal closure, and over a longer postoperative period is warranted to better inform sternal precautions and optimise postoperative recovery.

OBJECTIVE: Despite no evidence to support weight limitations following median sternotomy, sternal precautions continue to be routinely prescribed. Moreover, international cardiac rehabilitation guidelines lack sufficient detail for the implementation of resistance training. This systematic review and meta-analysis aimed to determine what the literature defines as resistance training; how resistance training is applied, progressed and evaluated; and, whether resistance training improves physical and functional recovery postoperatively in the cardiac surgical population. DATA SOURCES: Five (5) electronic databases were searched from inception to 28 September 2018 for studies published in English that investigated the effects of a resistance training intervention on physical and functional recovery following median sternotomy. RESULTS: Eighteen (18) trials (n=3,462) met eligibility criteria and were included in the analysis. Seven (7) randomised controlled trials shared common outcome measures, allowing meta-analysis. The performance of resistance training appears to be safe and feasible, and resulted in similar improvements in both cardiopulmonary capacity and anthropometry, when compared to aerobic training alone. However, the definition and application of resistance training is frequently a lower intensity and volume than recommended by the American College of Sports Medicine. Furthermore, sternal precautions are not reflective of the kinematics and weights used when performing many activities of daily living. For this reason, resistance training needs to be task-specific, reflecting functional tasks to promote recovery. CONCLUSION: Resistance training, in isolation or when combined with aerobic training, may lead to greater improvements in physical and functional recovery following cardiac surgery via median sternotomy; however, further research is required to inform clinical guidelines.

OBJECTIVE: The aim of this systematic review was to identify exercise parameters and outcome measures used in cardiac rehabilitation programs following median sternotomy, in the elderly cardiac population. DATA SOURCES: Five (5) electronic databases were searched for relevant studies published in English after 1997. STUDY SELECTION: The screening process was completed by two independent researchers, with a third independent reviewer for overall agreement. Studies were selected if they included only cardiac patients aged ≥65 years who had undergone valve surgery and/or coronary artery bypass grafting via median sternotomy, and who had undertaken a postoperative cardiac rehabilitation exercise intervention assessing physical function and/or cognitive recovery as outcomes. DATA EXTRACTION: Two researchers independently completed the data extraction and quality assessment. Quality was assessed using a modified Downs and Black tool. DATA SYNTHESIS: In total, 11 articles were included for appraisal with respect to the quality of the study. Only two randomised controlled trials were suitable for meta-analysis. A higher volume of exercise was shown to have a positive effect on functional recovery, assessed using the 6-minute walk test (6MWT) (mean difference=26.97m; 95% confidence interval [CI], 6.96-46.97; p=0.008; I2=0%). No significant improvement was shown between additional exercise compared to standard care in improving VO2peak, maximal power output or quality of life. No studies evaluated the effect of exercise on cognitive recovery. CONCLUSIONS: Exercise significantly improves functional recovery in the post-surgical elderly cardiac population, however uncertainty still exists with regard to which modes of exercise and their specific parameters are most effective in improving cognitive recovery.

OBJECTIVE: To investigate the effect of a supervised upper limb (UL) program (SULP) compared to no supervised UL program (NULP) after lung transplantation (LTx). DESIGN: Randomized controlled trial. SETTING: Physiotherapy gym. PARTICIPANTS: Participants (N=80; mean age, 56±11y; 37 [46%] men) were recruited after LTx. INTERVENTIONS: All participants underwent lower limb strength thrice weekly and endurance training. Participants randomized to SULP completed progressive UL strength training program using handheld weights and adjustable pulley equipment. MAIN OUTCOME MEASURES: Overall bodily pain was rated on the visual analog scale. Shoulder flexion and abduction muscle strength were measured on a hand held dynamometer. Health related quality of life was measured with Medical Outcomes Study 36-item Short Form health Survey and the Quick Dash. Measurements were made at baseline, 6 weeks, 12 weeks, and 6 months by blinded assessors. RESULTS: After 6 weeks of training, participants in the SULP (n=41) had less overall bodily pain on the visual analog scale than did participants in the NULP (n=36) (mean VAS bodily pain score, 2.1±1.3cm vs 3.8±1.7cm; P<.001) as well as greater UL strength than did participants in the NULP (mean peak force, 8.4±4.0Nm vs 6.7±2.8Nm; P=.037). At 12 weeks, participants in the SULP better quality of life related to bodily pain (76±17 vs 66±26; P=.05), but at 6 months there were no differences between the groups in any outcome measures. No serious adverse events were reported. CONCLUSIONS: UL rehabilitation results in short-term improvements in pain and muscle strength after LTx, but no longer-term effects were evident.

STUDY DESIGN: Psychometric. OBJECTIVES: Assess the validity of bioimpedance-based measures of fat-free mass (FFM) in acute SCI and of current definitions of obesity based on body mass index (BMI). SETTING: Australia. METHODS: All admissions within eight weeks of a new traumatic SCI were screened. 29% were eligible. 71% of those consented. Twenty participants (18 male) completed deuterium dilution (DD) and bioimpedance-based measurements of FFM. Thirteen also underwent dual-energy x-ray absorptiometry. Strength of relationships and agreement were examined using Lin's concordance coefficient and limits of agreement analysis, respectively. Sensitivity and specificity were calculated for three BMI cutoffs for obesity, using percentage fat mass (%FM) obtained from DD as reference. RESULTS: Median time since injury was 41 days (IQR 28-48). FFM from DD and DXA were highly correlated but not identical. Concordance and agreement between DD and seven bioimpedance-based predictive equations are presented. The best-fitting equation demonstrated a low bias (+0.6 kg) and moderate dispersion (±5.2 kg). The cutoff for overweight in able-bodied people (BMI ≥25 kg/m2) provided sensitivity of 43.8%, compared to 25% for the cut-off for obesity (BMI ≥30 kg/m2). FM from bioimpedance gave the highest sensitivity (88.9%). CONCLUSIONS: BMI demonstrates poor specificity to classify obesity in acute SCI. Present findings support the utility of bioimpedance-based measurements for estimating FFM in acute SCI for group comparisons. These results are generalizable to traumatic SCI 4-8 weeks post injury; however, the present data reflect a high proportion of high cervical injuries. Further research is indicated to establish validity for assessment of individuals and for longitudinal monitoring.
