Review
BACKGROUND
Exergame-based training is currently considered a more promising training approach than conventional physical and/or cognitive training.
OBJECTIVES
This study aimed to provide quantitative evidence on dose-response relationships of specific exercise and training variables (training components) of exergame-based training on cognitive functioning in middle-aged to older adults (MOA).
METHODS
We conducted a systematic review with meta-analysis including randomized controlled trials comparing the effects of exergame-based training to inactive control interventions on cognitive performance in MOA.
RESULTS
The systematic literature search identified 22,928 records of which 31 studies were included. The effectiveness of exergame-based training was significantly moderated by the following training components: body position for global cognitive functioning, the type of motor-cognitive training, training location, and training administration for complex attention, and exercise intensity for executive functions.
CONCLUSION
The effectiveness of exergame-based training was moderated by several training components that have in common that they enhance the ecological validity of the training (e.g., stepping movements in a standing position). Therefore, it seems paramount that future research focuses on developing innovative novel exergame-based training concepts that incorporate these (and other) training components to enhance their ecological validity and transferability to clinical practice. We provide specific evidence-based recommendations for the application of our research findings in research and practical settings and identified and discussed several areas of interest for future research.

Review
BACKGROUND
Sagittal imbalance can be caused by various etiologies and is among the most important indicators of spinal deformity. Sagittal balance can be restored through surgical intervention based on several radiographic measures. The purpose of this study is to review the normal parameters in the sitting position, which are not well understood and could have significant implications for non-ambulatory patients.
METHODS
A systematic review was performed adhering to PRISMA Guidelines. Using R-software, the weighted means and 95% confidence intervals of the radiographic findings were calculated using a random effect model and significance testing using unpaired t-tests.
RESULTS
10 articles with a total of 1066 subjects reported radiographic measures of subjects with no spinal deformity in the sitting and standing position. In the healthy individual, standing sagittal vertical axis -16.8°was significantly less than sitting 28.4° (p < 0.0001), while standing lumbar lordosis 43.3°is significantly greater than sitting 21.3° (p < 0.0001). Thoracic kyphosis was not significantly different between the two groups (p = 0.368). Standing sacral slope 34.3° was significantly greater than sitting 19.5° (p < 0.0001) and standing pelvic tilt 14.0° was significantly less than sitting 33.9° (p < 0.0001).
CONCLUSIONS
There are key differences between standing and sitting postures, which could lead to undue stress on surgical implants and poor outcomes, especially for non-ambulatory populations. There is a need for more studies reporting sitting and standing radiographic measures in different postures and spinal conditions.

OBJECTIVES
This systematic literature review and meta-analysis aimed to determine the effect of body position on the measurement of pelvic floor muscle (PFM) contractility and to analyze the influential factors.
DATA SOURCES
Five databases (PubMed, Web of Science, EMBASE, Cochrane Library and Scopus) were searched for relevant studies published up to 12nd October 2023.
STUDY SELECTION OR ELIGIBILITY CRITERIA
Included cross-sectional studies had to involve the assessment of pelvic floor muscle function in at least two positions.
STUDY APPRAISAL AND SYNTHESIS METHODS
We calculated standardized mean difference (SMD) with 95% confidence intervals (CI) to ascertain the potential effect of body position on outcomes.
RESULTS
In total, we included 11 cross-sectional studies to ascertain the potential effect of body position on outcomes. There was no statistical difference in the results of maximum voluntary contraction (MVC) of the pelvic floor muscles when assessed in between supine and standing positions (SMD -0.22; 95% CI -0.72 to 0.28; = 0.38). The results of the meta-analysis showed significantly larger values of resting voluntary contractions (RVC) measured in the standing position compared to the supine position (SMD -1.76; 95% CI -2.55 to -0.97; < 0.001). Moreover, pelvic floor muscle movement during pelvic floor muscle contraction in the standing position was significantly better than that measured in the supine position (SMD -0.47; 95% CI -0.73 to 0.20; < 0.001).
CONCLUSION
The results of this study showed that the RVC and PFM movement varied with the position of the assessment. In contrast, MVC values are independent of the assessment position and can be selected according to clinical needs.

Review
The rise of ultraendurance sports in the past two decades warrants evaluation of the impact on the heart and vessels of a growing number of athletes participating. Blood pressure is a simple, inexpensive method to evaluate one dimension of an athlete's cardiovascular health. No systematic review or meta-analysis to date has chronicled and delineated the effects of ultraendurance races, such as ultramarathons, marathons, half-marathons, and Ironman triathlon events, specifically on heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), and mean arterial pressure (MAP) measurements in supine and standing positions before and after the event. This meta-analysis reviews the effects of ultraendurance events on positional and calculated hemodynamic values. Data were extracted from 38 studies and analyzed using a random effects model with a total of 1,645 total blood pressure measurements. Of these, 326 values were obtained from a standing position, and 1,319 blood pressures were taken supine. Pre-race and post-race measurements were evaluated for clinical significance using established standards of hypotension and orthostasis. HR and calculated BP features, such as PP and MAP, were evaluated. Across all included studies, the mean supine post-race HR increased by 21±8 beats per minute (bpm) compared to pre-race values. The mean standing post-race HR increased by 23±14 bpm when compared with pre-race HR. Overall, there was a mean SBP decrease of 19±9 mmHg and a DBP decrease of 9±5 mmHg post-race versus pre-race values. MAP variations reflected SBP and DBP changes. The mean supine and standing pre-race blood pressures across studies were systolic (126±7; 124±14) and diastolic (76±6; 75±12), suggesting that some athletes may enter races with existing hypertension. The post-race increase in the mean HR and decline in mean blood pressure across examined studies suggest that during long-term events, ultramarathon athletes perform with relatively asymptomatic hypotension.

Meta-Analysis
Background Rapidly consuming water may offer practical orthostatic hypotension therapy. However, its efficacy across disorders remains uncertain. This study aims to assess the impact of rapid 350- to 500-mL water intake on systolic and diastolic blood pressure (BP) and heart rate (HR) through a systematic review and meta-analysis. Methods and Results We systematically reviewed MEDLINE and Embase up to June 2023, including randomized controlled trials and prospective cohort studies. Using random-effects meta-analysis, we calculated pooled mean differences (MDs) for maximum hemodynamic effects of rapid 350- to 500-mL water bolus consumption. Participants with orthostatic hypotension experienced increased systolic BP (MD, 24.18 [95% CI, 15.48-32.88]) and diastolic BP (MD, 11.98 [95% CI, 8.87-15.09]) with decreased HR (MD, -3.46 [95% CI, -5.21 to -1.71]). Similar results were observed in multiple system atrophy and pure autonomic failure subgroup analysis. Healthy participants showed modest increases in systolic BP (MD, 2.33 [95% CI, 1.02-3.64]) and diastolic BP (MD, 2.73 [95% CI, 1.15-4.30]), but HR changes were not significant (MD, -2.06 [95% CI, -5.25 to 1.13]). Water had no significant hemodynamic effects in patients with seated or supine postural tachycardia syndrome, although standing effects were unassessed. Our data do not exclude water's potential standing effect in postural tachycardia syndrome. Conclusions In patients with orthostatic hypotension, rapid water intake elevated short-term systolic BP and diastolic BP, with mild HR reduction when seated or supine. Healthy participants exhibited similar but milder effects. However, patients with postural tachycardia syndrome did not experience these changes in seated or supine positions. Further research is needed to evaluate the promising impact of rapid water ingestion on patients with postural tachycardia syndrome in a standing position, which was not addressed in our study.

Comparative Study Meta-Analysis
IMPORTANCE
There are ongoing concerns about the benefits of intensive vs standard blood pressure (BP) treatment among adults with orthostatic hypotension or standing hypotension.
OBJECTIVE
To determine the effect of a lower BP treatment goal or active therapy vs a standard BP treatment goal or placebo on cardiovascular disease (CVD) or all-cause mortality in strata of baseline orthostatic hypotension or baseline standing hypotension.
DATA SOURCES
Individual participant data meta-analysis based on a systematic review of MEDLINE, EMBASE, and CENTRAL databases through May 13, 2022.
STUDY SELECTION
Randomized trials of BP pharmacologic treatment (more intensive BP goal or active agent) with orthostatic hypotension assessments.
DATA EXTRACTION AND SYNTHESIS
Individual participant data meta-analysis extracted following PRISMA guidelines. Effects were determined using Cox proportional hazard models using a single-stage approach.
MAIN OUTCOMES AND MEASURES
Main outcomes were CVD or all-cause mortality. Orthostatic hypotension was defined as a decrease in systolic BP of at least 20 mm Hg and/or diastolic BP of at least 10 mm Hg after changing position from sitting to standing. Standing hypotension was defined as a standing systolic BP of 110 mm Hg or less or standing diastolic BP of 60 mm Hg or less.
RESULTS
The 9 trials included 29 235 participants followed up for a median of 4 years (mean age, 69.0 [SD, 10.9] years; 48% women). There were 9% with orthostatic hypotension and 5% with standing hypotension at baseline. More intensive BP treatment or active therapy lowered risk of CVD or all-cause mortality among those without baseline orthostatic hypotension (hazard ratio [HR], 0.81; 95% CI, 0.76-0.86) similarly to those with baseline orthostatic hypotension (HR, 0.83; 95% CI, 0.70-1.00; P = .68 for interaction of treatment with baseline orthostatic hypotension). More intensive BP treatment or active therapy lowered risk of CVD or all-cause mortality among those without baseline standing hypotension (HR, 0.80; 95% CI, 0.75-0.85), and nonsignificantly among those with baseline standing hypotension (HR, 0.94; 95% CI, 0.75-1.18). Effects did not differ by baseline standing hypotension (P = .16 for interaction of treatment with baseline standing hypotension).
CONCLUSIONS AND RELEVANCE
In this population of hypertension trial participants, intensive therapy reduced risk of CVD or all-cause mortality regardless of orthostatic hypotension without evidence for different effects among those with standing hypotension.

Review
Dysfunctions of the lumbosacral area and related pain syndromes, such as chronic low back pain (CLBP), are among the most common musculoskeletal problems in modern society. The purpose of this study was to evaluate the effectiveness of isolated myofascial release techniques (MFR) in the treatment of CLBP in adults. PubMed, Web of Science, Scopus, and Cochrane Library databases were searched for studies published from 1 January 2013 to 1 March 2023. We included English-language randomized controlled trials evaluating the effect of isolated MFR performed by a specialist on adults with CLBP. Only studies with a comparison group without treatment or with sham MFR were included. A total of 373 studies were detected, of which 6 studies were finally included in this review. There was a total of 397 CLBP patients aged 18-60 in all study groups. The studies evaluated the effects of a series of MFR treatments as well as a single intervention. After applying a series of treatments, a statistically significant reduction in pain intensity, improvement in the range of motion, reduction in the level of functional disability and fear-avoidance beliefs, as well as a decrease in the activity of paraspinal muscles at maximum trunk flexion were demonstrated. A single, 40-min complex intervention involving tissues at various depths significantly reduced the level of pain, improved the range of motion, and reduced the resting activity of paraspinal muscles in the standing position, but did not affect postural stability. The use of a single 5 min MFR technique did not affect pain intensity and sensitivity and functional disability. The findings suggest that the use of a series of isolated MFR improves the condition of patients with CLBP by reducing the intensity of pain, improving functional efficiency, and reducing the activity of the paraspinal muscles in the position of maximum forward bend. The use of a single intervention containing a set of techniques covering superficial and deep tissue also reduces the intensity of pain, improves mobility, and reduces the resting activity of the paraspinal muscles in a standing position. Given the small number of eligible studies with limitations, conclusions should be interpreted with caution and avoid overgeneralizing the benefits of isolated MFR based on limited or mixed evidence.

Meta-Analysis
OBJECTIVES
The association between occupational mechanical exposures and low-back pain (LBP) has been studied in several systematic reviews. However, no systematic review addressing chronic LBP exists. The aim of this systematic review and meta-analysis was to examine the association between occupational mechanical exposures and chronic LBP.
METHODS
The study was registered in PROSPERO. We used an existing systematic review to identify articles published before January 2014. For studies published between January 2014 and September 2022, a systematic literature search was conducted in six databases. Two authors independently excluded articles, extracted data, and assessed risk of bias and level of evidence (GRADE). Meta-analyses were conducted using random-effects models comparing highest versus lowest exposure group with sensitivity analyses based on study quality (low/moderate versus high risk of bias), study design (cohort versus case-control), and outcome definition (non-specific LBP versus specific chronic LBP).
RESULTS
Twenty-six articles were included. Highest pooled odd ratios (OR) were found for combined mechanical exposures [OR 2.2, 95% confidence interval (CI) 1.4-3.6], lifting/carrying loads (OR 1.7, 95% CI 1.4-2.2), and non-neutral postures (OR 1.5, 95% CI 1.2-1.9). For the remaining mechanical exposures (ie, whole-body vibrations, standing/walking, and sitting), OR ranged between 1.0 and 1.4. In the sensitivity analyses, generally, higher pooled OR were found in low/moderate risk of bias studies, case-control studies, and studies of specific chronic LBP.
CONCLUSIONS
Moderate evidence of an association was found for lifting/carrying loads, non-neutral postures, and combined mechanical exposures. Low or very low evidence was found for whole-body vibrations, standing/walking, and sitting. Studies using standardized exposure definition, metric, and technical measurements are highly warranted.

PURPOSE
To report accuracy, repeatability, and agreement of Cobb angle measurements on radiographs and/or stereo-radiographs (EOS) compared against one another or against other imaging modalities.
METHODS
This review follows Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. A literature search was conducted on 21 July 2021 using Medline, Embase, and Cochrane. Two researchers independently performed title/abstract/full-text screening and data extraction. Studies were eligible if they reported Cobb angles, and/or their repeatability and agreement, measured on radiographs and/or EOS compared against one another or against other imaging modalities.
RESULTS
Of the 2993 records identified, 845 were duplicates and 2212 were excluded during title/abstract/full-text screening. Two more relevant studies were identified from references of eligible studies, leaving 14 studies for inclusion. Two studies compared Cobb angles from EOS vs CT, while 12 compared radiographs vs other imaging modalities: EOS, CT, MRI, digital fluoroscopy, or dual-energy x-ray absorptiometry. Angles from standing radiographs tended to be higher than those from supine MRI and CT, and angles from standing EOS tended to be higher than those from supine or prone CT. Correlations across modalities were strong (R = 0.78-0.97). Inter-observer agreement was excellent for all studies (ICC = 0.77-1.00), except one (ICC = 0.13 radiographs and ICC = 0.68 for MRI).
CONCLUSION
Differences of up to 11º were found when comparing Cobb angles across combinations of imaging modalities and patient positions. It is not possible, however, to determine whether the differences observed are due to the change of modality, position, or both. Therefore, clinicians should be careful when utilizing the thresholds for standing radiographs across other modalities and positions for diagnosis and assessment of scoliosis.

Meta-Analysis
BACKGROUND
Incomplete spinal cord injury (iSCI) often results in impaired balance leading to functional impairments. Recovery of standing balance ability is an important aim of rehabilitative programs. However, limited information is available on effective balance training protocols for individuals with iSCI.
OBJECTIVES
To assess the methodological quality and effectiveness of various rehabilitation interventions for improving standing balance in individuals with iSCI.
METHODS
A systematic search was performed in SCOPUS, PEDro, PubMed, and Web of Science from inception until March 2021. Two independent reviewers screened articles for inclusion, extracted data, and evaluated methodological quality of the trials. PEDro Scale was used to assess the quality of randomized controlled trials (RCT) and crossover studies while pre-post trials were assessed using the modified Downs and Black tool. A meta-analysis was performed to quantitatively describe the results. The random effects model was applied to present the pooled effect.
RESULTS
Ten RCTs with a total of 222 participants and 15 pre-post trials with 967 participants were analyzed. The mean PEDro score and modified Downs and Black score was 7/10 and 6/9, respectively. The pooled standardized mean difference (SMD) for controlled and uncontrolled trials of body weight-supported training (BWST) interventions was -0.26 (95% CI, -0.70 to 0.18; = .25) and 0.46 (95% CI, 0.33 to 0.59; < .001), respectively. The pooled effect size of -0.98 (95% CI, -1.93 to -0.03; = .04) indicated significant improvements in balance after a combination of BWST and stimulation. Pre-post studies analyzing the effect of virtual reality (VR) training interventions on Berg Balance Scale (BBS) scores in individuals with iSCI reported a mean difference (MD) of 4.22 (95% CI, 1.78 to 6.66; = .0007). Small effect sizes were seen in pre-post studies of VR+stimulation and aerobic exercise training interventions indicating no significant improvements after training on standing balance measures.
CONCLUSION
This study demonstrated weak evidence to support the use of BWST interventions for overground training for balance rehabilitation in individuals with iSCI. A combination of BWST with stimulation however showed promising results. There is a need for further RCTs in this field to generalize findings. Virtual reality-based balance training has shown significant improvement in standing balance post iSCI. However, these results are based on single group pre-post trials and lack appropriately powered RCTs involving a larger sample size to support this intervention. Given the importance of balance control underpinning all aspects of daily activities, there is a need for further well-designed and appropriately powered RCTs to evaluate specific features of training interventions to improve standing balance function in iSCI.
