Variable Resistance Training Combined With Static Traction Computer Vision Applied in Neck and Shoulder Rehabilitation Training for College Students

This study evaluates the effectiveness of static traction combined with variable resistance training in rehabilitating college students with neck and shoulder diseases. Ninety students were randomly assigned to receive either static traction alone or combined therapy. Visual analogue scale (VAS), neck disability index (NDI), cervical range of motion, electromyography (EMG), and soft tissue parameters were assessed pre- and post-treatment. Both groups showed improved VAS and NDI scores post-treatment, with greater enhancements in the combined therapy group. Cervical range of motion, EMG values, and soft tissue parameters also favored the combined therapy. Statistical analysis revealed significant differences (P<0.05) between groups. Static traction combined with variable resistance training effectively improves neck and shoulder function, reduces pain, and enhances rehabilitation outcomes compared to static traction alone. This approach shows promise for optimizing rehabilitation in college students with similar musculoskeletal conditions.

Effectiveness of Transforaminal Epidural Steroid Injection and Lumbar Traction in Lumbar Radiculopathy Due to Intervertebral Disc Herniation: A Comparative Study

Background: Lumbar radiculopathy, commonly caused by intervertebral disc herniation, leads to severe pain and disability. Various non-surgical treatments, including Transforaminal Epidural Steroid Injection (TESI) and lumbar traction, are employed to alleviate pain and improve functionality. Objective: The study aimed to compare the effectiveness of TESI and lumbar traction in managing lumbar radiculopathy. Methods: This study was designed as a prospective, randomized, comparative trial conducted over 12 months at a tertiary care center, involving 100 patients diagnosed with lumbar radiculopathy due to intervertebral disc herniation (IDH). Eligible patients, aged 18 to 65 years with MRI-confirmed disc herniation causing radiculopathy, were randomly assigned to either the TESI group (n=50) or the lumbar traction group (n=50). Exclusion criteria included patients with prior lumbar surgery, spinal infections, or tumors. The TESI group received a single transforaminal epidural steroid injection under fluoroscopic guidance, while the lumbar traction group underwent mechanical traction therapy for 30 minutes per session, three times a week for six weeks. Outcome measures included pain intensity, assessed using the Visual Analog Scale (VAS) at baseline, two weeks, and six months post-intervention, functional outcome using the Oswestry Disability Index (ODI) at the same time points, and patient satisfaction using a five-point Likert scale at six months. Statistical analyses were conducted using SPSS software, with significance set at p-values <0.05. Results: The results of this study demonstrated that both the TESI and lumbar traction groups experienced significant improvements in pain and functional outcomes; however, the TESI group showed more pronounced results. In terms of pain reduction, the TESI group’s mean VAS score decreased from 7.5 at baseline to 3.2 at two weeks and 2.8 at six months, while the lumbar traction group saw a decrease from 7.6 to 5.1 at two ........

Synergistic chemical traction and pre-intercalation strategies enable high-quality MnO2 composites for efficient ammonium capture

The δ-MnO2 exhibits an ideal capacitive deionization (CDI) electrode for the efficient removal of ammonium ions (NH4+), owing to its unique layered structure that facilitates effective insertion and extraction of ions. However, MnO2 is constrained by self-aggregation, inadequate electrical conductivity, and sluggish reaction kinetics in practical applications, leading to subpar ammonium removal performance. Here, the polyaniline (PANI) intercalated MnO2 and carbon nanotubes (CNTs) composites (P/M-C-X) were synthesized by a straightforward and swift one-step inorganic/organic interface reaction using the chemical traction effect of aniline. The synergistic effect of the increased layer spacing and the introduced oxygen vacancy after PANI intercalated and the 1D/2D conductive interconnect structure constructed by CNTs can effectively improve the electrical conductivity, promote ions/electrons diffusion, and enhance the charge reaction kinetics. As results, P/M-C-50 exhibits excellent NH4+ removal performance, including the maximum salt adsorption capacity (SAC) (160.0 mg g−1), ultra-high salt adsorption rate (SAR) (1.07 mg g−1 s−1), and good cyclic stability. Furthermore, the comprehension of NH4+ storage mechanism has been enhanced through structural characterization, electrochemical analysis, and theoretical calculation. This study shows that P/M-C-50 has broad potential as a CDI ammonium removal electrode, and lays a solid foundation for the effective recovery and reuse of ammonium resources.

Effect of cervical traction on cervicogenic headache in patients with cervical radiculopathy: a preliminary randomized controlled trial

BackgroundCervical radiculopathy (CR) is a common condition, often associated with cervicogenic headache (CGH), a secondary headache arising from cervical spine disorders. Mechanical intermittent cervical traction (MICT) is frequently prescribed to treat CR symptoms. The purpose of the study was to make a preliminary estimate of efficacy of adding MICT to conventional rehabilitation on CGH in patients with cervical radiculopathy.MethodsA total of 36 CR patients with CGH were randomly allocated to 3 equally sized groups (A, B and C). The treatment consisted of twelve sessions of conventional rehabilitation (4 weeks) combined with MICT (2 kg for group A, 8 kg for group B and 12 kg for group C). Primary outcomes were CGH intensity (visual analog scale) and frequency (days per week). Secondary outcomes were radicular pain intensity (visual analog scale), cervical range of motion (cervical range of motion instrument), proprioception (cervical range of motion instrument) and muscle strength (MicroFET2 dynamometer), handgrip strength (handheld dynamometer), function (Neck Disability Index), kinesiophobia (Tampa Scale for KInesiophobia), anxiety and depression (Hospital Anxiety and Depresion questionnaire), and quality of life (World Health Organization Quality of Life). Patients were assessed at baseline, one, three and six months after the beginning of treatment. The post hoc Dunn testing was used to determine which traction load had the better effect on CGH symptoms.ResultsAt one, three and six months follow-ups, Group C exhibited the highest improvement in CGH intensity and frequency compared to the other groups (p = 0.021 and p = 0.023; p = 0.012 and p = 0.01; p = 0.005 and p = 0.005). Both groups C and B showed a significant improvement in radicular pain compared to group A at one month follow-up (p = 0.05).The improvement in group C was significantly better in terms of function (p = 0.049) and anxiety (p = 0.011) at three months and quality of life at six months (Psychological p = 0.046 and Environment p = 0.006).ConclusionsThe blend of conventional rehabilitation alongside 12 kg MICT seems to be efficacious in diminishing both the intensity and frequency of CGH in patients with CR. These advantages appear to last for up to six months following the treatment period, potentially leading to decreased CGH severity and occurrence rates, heightened functionality, reduced anxiety levels, and an overall enhancement in quality of life. These findings are preliminary and require confirmation in larger trials.Trial registrationThe study protocol was retrospectively registered at the Pan African Clinical Trial Registry (PACTR202401838955948). Date of registration is 16/01/2024.

Impact of retinal traction induced by epiretinal membrane on aniseikonia

We investigated the effect of retinal traction caused by epiretinal membranes (ERMs) on aniseikonia and retinal microstructures in 81 unilateral ERMs. Retinal traction was quantified by measuring the maximum depth of the retinal fold (MDRF) using en face optical coherence tomography (OCT) images. Measurements included the mean inner nuclear layer (INL), outer plexiform layer (OPL), outer nuclear layer (ONL), central retinal thickness (CRT), and interocular ratios of the foveal avascular zone (FAZ) area (FAZ ratio). Significant correlations were found between the preoperative MDRF and preoperative aniseikonia (P < 0.001), INL thickness (P < 0.001), CRT (P < 0.001), and FAZ ratio (P = 0.003). Preoperative aniseikonia was significantly correlated with preoperative INL and OPL-ONL thicknesses (P < 0.001 and P = 0.020, respectively) and CRT (P = 0.003). Multiple regression analysis revealed that preoperative aniseikonia was significantly associated with preoperative MDRF, INL, and OPL-ONL thicknesses (P = 0.029, 0.006, and 0.006, respectively). Twenty-nine eyes underwent membrane peeling, resolving all retinal folds 6 months postoperatively. A significant correlation was observed between preoperative MDRF and postoperative aniseikonia (P = 0.011). Our findings suggest that retinal traction by ERM is significantly associated with aniseikonia both pre- and postoperatively, alongside other OCT parameters.

Design and Test of Hydraulic Bottom Seal Fracturing Tool for Coiled Tubing

Abstract As the main tool for reservoir reconstruction of Longdong shale reservoir in Changqing Oilfield, the coiled tubing bottom seal drag-segment fracturing tool is currently in the stage of scale promotion, providing tool support for the efficient development of Longdong shale oil. However, in the process of horizontal construction with large water vertical ratio and super long horizontal section, there are construction problems such as natural depth limitation of the tool and difficulty in setting the bottom packer, which seriously affect the construction efficiency and quality. In view of the above problems, this paper carried out the development of pumped coiled tubing hydraulic bottom seal drag-segment fracturing tool. With the technical ideas of pumping cup deepening and hydraulic setting bottom packer, the hydraulic setting type bottom packer, soluble cup pumping sub and supporting tools were designed and developed. By using the method of annular pumping and tubing accompanying injection, the tail cup pumping sub was used to generate throttle and larger cup outer diameter, forming a large hydraulic traction force to carry the tool string to break the depth limit. Without applying drilling pressure, the bottom packer was set by oil injection and displacement, and the setting state was lifted and lifted after the fracturing construction, providing a reliable tool scheme for solving the above engineering problems. The indoor evaluation results show that the traction effect of the bowl pumping short joint with small displacement of water is good, the bottom packer is smooth in the setting and unpacking action at 120°C, and the sealing is reliable under 70MPa pressure. The overall test of the tool string can realize the setting and unpacking action without the intervention of drill pressure. Six well tests were carried out in the field. The pumping depth was 430m under the condition of 740L/min water pumping displacement, and the oil injection displacement was increased to 550L/min. The hydraulic setting was fast and reliable, which effectively improved the construction capacity of the coiled tubing fracturing tool in the ultra-long horizontal well, greatly shortened the time consumption of interlayer conversion, and improved the speed and efficiency significantly.

Traction MRI of the Elbow: Age-Based Effects and Implications.

We previously reported that traction magnetic resonance imaging (MRI) of the elbow without arthrography increases the width of the radiocapitellar joint (RC) and improves articular cartilage visibility. However, the effects of axial traction on different age groups have not yet been evaluated. We hypothesized that the effect of traction would decrease as the participants' age increased. We enrolled 30 healthy volunteers, ten each in their 20s, 30s, and 40s. The male-to-female ratio in each age group was 1:1. Elbow MRI was performed without traction and with 3, 5, and 7 kg axial traction. We evaluated joint space width (JW), humeral articular cartilage visibility, and intraprocedural pain/discomfort. We measured JW and cartilage visibility at the RC and the lateral and medial thirds of the ulnohumeral joint. The older age groups exhibited narrower JWs without traction. Axial traction increased the JW and improved the visibility of the RC in all age groups. No significant differences were observed in the ulnohumeral joint's lateral or medial thirds, but pain and discomfort increased with heavier traction weights. For participants in their 20s and 30s, axial traction of 3 kg seemed appropriate, while 7 kg traction was considered for those in their 40s.

Investigation of aerodynamic loss mechanism on turbine leading edge with slot film cooling based on entropy analysis

Discrete film holes are a widely used cooling structure, with increasing cooling performance demands making their optimization increasingly complex. The structure of slot cooling is simpler compared to discrete holes, but it results in greater flow losses while improving cooling performance. To elucidate the sources and mechanisms of losses in slot cooling, this study employs numerical simulations based on the Reynolds-averaged Navier-Stokes (RANS) method. The investigation focuses on the leading-edge cooling of high-pressure turbine guide vanes, using entropy analysis to thoroughly examine the effects of blowing ratio (M) and slot spacing on loss location, composition, characteristics, and mechanisms. The results indicate that the losses associated with hole structures are not sensitive to changes in blowing ratio, while the entropy generation in slot structures generally increases with higher blowing ratios. Near the corner region, the traction effect of the horseshoe vortex expands the thermal loss region of the coolant, weakening the heat exchange in hole structures but significantly enhancing it in slot structures. The hole/slot structures have a minimal impact on the location of the passage vortex core, reducing the cross-flow velocity and cross-flow layer thickness. The greater flow losses are primarily due to increased passage vortex intensity. Slot cooling can achieve superior cooling performance at low M compared to hole structures at high M, with both having similar total pressure loss. However, the thermal losses for slot structures increase by approximately 55 % compared to hole structures on the pressure side of the leading edge, with even more significant increases on the suction side, while the maximum increase in viscous losses is only about 10 %.

Effectiveness and side effects of orthodontic traction of impacted maxillary incisors in a labially inverted position: A systematic review

Treatment of impacted upper incisors in a labially inverted position is challenging for orthodontists, and its prognosis has not been established in the literature. Thus, this systematic review aimed to determine the effectiveness and side effects of orthodontic traction of impacted maxillary incisors in a labially inverted position. A comprehensive search was conducted in multiple databases, including MEDLINE (via PubMed), Scopus, Embase, Science Direct, and LILACS, up to June 30, 2024. Initially, 1640 articles were identified, and after applying specific selection criteria, 11 articles were selected for full-text evaluation. Following the review, only six studies were deemed relevant, comprising one before-and-after study, two longitudinal retrospective studies, and three cross-sectional studies. Newcastle-Ottawa and Risk of Bias (ROB-2) tools were used to assess the risk of bias in the selected studies. The average duration of traction for maxillary labially inverted impacted central incisors ranged from 8.60±1.26months to 18±6.0months, with all cases being successfully treated. Following traction, the clinical crown height of the incisors was significantly higher compared to the control group (P<0.01). Similarly, the root length of the impacted incisors after traction was shorter in the impaction group (approximately 2mm) compared to the control group. Likewise, the thickness of the alveolar bone varied among different studies. Some authors noted that the treatment group had a smaller thickness (about 0.5mm) compared to the control group (P<0.05), while other authors found similar thickness after treatment. Although there are few reported studies with a low risk of bias, it is clear that it is possible to successfully treat labially inverted impacted maxillary central incisors with apparently few side effects. Following traction, the clinical crown height of these incisors increased, while the root length was shorter than their normally erupted contralateral teeth.

Effectiveness of vacuum-assisted wound closure and mesh-mediated fascial traction in open abdomen management.

To determine the effectiveness of vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) in patients undergoing open abdomen management (OAM). Data from cases with OAM for at least five days who were admitted to our institution between January 2011 and December 2020 were included. We compared the patient's age, sex, medical history, indication for initial surgery, APACHE II scores, indication for OAM, operative time, intraoperative blood loss, intraoperative transfusion, success of primary fascial closure (rectus fascial closure and bilateral anterior rectus abdominis sheath turnover flap method), success of planned ventral hernia, duration of OAM, and in-hospital mortality between patients undergoing VAWCM (VAWCM cases, n = 27) and vacuum-assisted wound closure (VAWC) alone (VAWC cases, n = 25). VAWCM cases had a significantly higher success rate of primary fascial closure (70% vs. 36%, p = 0.030) and lower in-hospital mortality (26% vs. 72%, p = 0.002) than VAWC cases. A multivariate logistic regression analysis showed that VAWCM was an independent factor influencing in-hospital mortality (odds ratio, 0.14; 95% confidence interval: 0.04-0.53; p = 0.004). VAWCM is associated with an increased rate of successful primary fascial closure and may reduce in-hospital mortality.

A comparative study of a two-stage surgical approach combining coronectomy with microimplant anchorage traction for extraction of impacted mandibular third molars with different traction angles

Objective: To establish a two-stage surgical procedure of impacted mandibular third molars (IMTMs) extractions assisted by coronectomy and microimplant anchorage traction and to investigate the influencing factors of root movement and the effects of different traction angles on the clinical outcomes. Methods: Fifty-three IMTM in contact with inferior alveolar nerve (IAN) that underwent tooth extraction in the Peking University School of Stomatology from January 2022 to June 2023 were included, with coronectomy and microimplant anchorage implantation in the first stage of the surgery, root traction was achieved with orthodontic elastic and microimplant anchorages by about 600 g of force, when the IMTM root was detached from IAN, a second surgery was performed to extract the residual root. The basic information of patients and M3M, data on the microimplant anchorage implantation and traction, imaging measurements, and complications were recorded and analyzed. Results: The movement distance of the residual roots was (1.80±0.92) mm, and the duration of traction was (32.9±7.9) d. Multiple linear regression analysis showed that the residual root movement distance was significantly correlated with age, gender, number of roots, traction angle, and depth of the distal bone defect of the second molar (P<0.05). The smaller the traction angle, the more significant the movement of the residual roots (P=0.044). In one case (1.9%, 1/53), the patient experienced abnormal sensation in the lower lip 16 days after traction. Conclusions: The two-stage surgical method of combined coronectomy with rapid traction technique to extract the IMTM allows for rapid movement of the residual root and reduces the risk of IAN injury. The efficiency of root movement can be accelerated by appropriately reducing the traction angle during surgery. The traction effect can be predicted based on indicators such as age, gender, number of roots and depth of distal bone defects of second molar.

The effect of cervical traction on stabilometric parameters in cervical radiculopathy patients: A randomized crossover study.

Cervical traction is effective on pain and function in patients with cervical radiculopathy but its effectiveness on balance disorders has not yet been studied. To evaluate the effect of mechanical intermittent cervical traction (MICT) on stabilometric parameters in patients with cervical radiculopathy. This randomized crossover study assigned 20patients with cervical radiculopathy to one of the two groups: Group effective traction (ET)/sham traction (ST) (n= 10) treated firstly with ET (traction force of 12Kg) then with ST (traction force of 2Kg) with one-week interval and group ST/ET (n= 10) treated invertedly with a ST then ET. Each traction procedure was maintained for 10minutes twice separated by 5minutes of rest. Patients were assessed before and immediately after MICT procedure. Main outcome measures were stabilometric parameters: center of pressure, sway area and lateral and anteroposterior displacements using a force platform. Secondary outcome measures were pain intensity, grip strength and dizziness. ET has provided a significantly greater improvement in both groups and in the total population in terms of stabilometric parameters (p< 0.01), pain intensity, and grip strength (p< 0.05), compared to ST. MICT seems to have an immediate beneficial effect on stabilometric parameters, pain and grip strength in patients with cervical radiculopathy.

Time-series traction prediction of surrounding rock deformation in tunnel construction based on mechanical parameter inversion

The deformation of the surrounding rock serves as a macroscopic representation of the stability status of the tunnel, and is also an important indicator for stability evaluation. To address the difficulty of accurately predicting long-term deformation in tunnel surrounding rock with limited monitoring data, a time-series traction prediction method based on the inversion of mechanical parameters was proposed. Employing the adaptive vigilance chaotic sparrow search algorithm (ACSSA) to optimize initial parameters in extreme learning machines (ELM) and long short-term memory (LSTM) neural networks. It then constructed two deformation time-series prediction models and a rock mechanics parameter inversion model based on the ACSSA-ELM and ACSSA-AMLSTM algorithms. Based on the mechanical parameter inversion model and numerical simulation, the value of the surrounding rock deformation at the key construction nodes of the tunnel was calculated as the traction point, and the traction interval and traction control equation were defined. Cubic spline interpolation and wavelet decomposition were employed to preprocess the measured deformation data of the surrounding rock. Subsequently, the proposed time-series prediction model was utilized for prediction. The predicted results within the traction interval undergo correction based on the traction points, thereby achieving a more precise and intelligent prediction of the tunnel surrounding rock deformation. Based on literature cases and data from the Huayang Tunnel project in Chongqing, the proposed method was validated and applied. The model's accuracy has been validated and successfully guided construction and production. Finally, the impact of different methods on traction effectiveness and the distribution pattern of traction points on model performance was discussed.

Size/Shape-Controllable Carbonized Wood Electrodes Enabled by an MXene Shell with Spatial Confinement and a Traction Effect on the Wood Cell Wall for Shape-Customizable Energy Storage Devices.

The shrinkage and collapse of wood cell walls during carbonization make it challenging to control the size and shape of carbonized wood (CW) through pre- or postprocessing (e.g., sawing, cutting, and milling). Herein, a shape-adaptive MXene shell (MS) is created on the surface of the wood cell walls. The MS limits the deformation of wood cell walls by spatial confinement and traction effects, which is supported by the inherent dimensional stability of the MS and the formation of new C-O-Ti covalent bonds between the wood cell wall and MS. Consequently, the volumetric shrinkage ratio of CW encapsulated by the MS (CW-MS) is significantly reduced from 54.8% for CW to 2.6% for CW-MS even at 800 °C. The harnessing of this collapse enables the production of CW-MS with prolonged stability and high electric conductivity (384 S m-1). These properties make CW-MS suitable for energy storage devices with various designed shapes, matching the increasingly compact and complex structures of electronic devices.

Traction modifies the contact area and the vertical and horizontal stress distributions beneath the tyre

Improving the prediction accuracy of the risk of soil structure deformation during wheeling requires a better understanding of the effects of traction on the vertical and horizontal stress distributions beneath tyres. In this study, these distributions were assessed for a rear wheel of a pulled (i.e., passive) and pulling (i.e., active) tractor during wheeling. The total load of the tractor was 85.2 kN, with a static rear wheel load of 33.0 kN on a 650/60 R38-tyre, inflated to 80 kPa. The 4WD was disabled in the active configuration. Vertical and horizontal contact stresses were measured at a frequency of 1 kHz using pressure transducers at 0.10 m depth of a sandy loam agricultural soil, covering a width of about 0.75 m, thereby capturing the entire stress distribution beneath the tyre. With these data, the contact characteristics (apparent wheel load, contact area, mean ground pressure) were calculated, the stress distributions characterised, and the ratio of horizontal to vertical stress for numerous positions beneath the rear tyre obtained. The results show that traction modifies the tyre-soil interaction significantly. The tyre-soil contact area was larger and the magnitude of vertical stress was lower for the active than for the passive tyre. On the other hand, the magnitude of horizontal stress was higher for the active than for the passive tyre. Consequently, the ratio of horizontal over vertical stress was higher beneath the active than beneath the passive tyre (P < 0.001), with median values of 1.0 and 0.5, respectively. Vertical and horizontal stress peak values did not spatially align but occurred in different positions beneath the active tyre. These findings thus contradict the assumption that horizontal stress near the tyre-soil interface is simply a function of vertical stress. Traction changed the distribution of vertical stress at the tyre-soil interface, with vertical stress peaking in different positions beneath the tyres, whilst the effects of traction on the horizontal stress was primarily related to the magnitude. The results of this study highlight the importance of incorporating different drive modes in predictions of the stress-state beneath a tyre and thus the assessment of the risk of soil deformation induced by wheeling.

Dynamic performance analysis of ball bearings with multi-factor coupling excitation

Skidding behavior and unstable cage whirling of bearings are key factors limiting the service performance of a spindle-bearing system. This study proposes an improved dynamic model of ball bearings focusing on structure deformations and poor lubrication conditions. The ring deformations induced by the radial preload for the spindle-bearing-pedestal mechanical system are first discussed, and the asperity contact and starved lubrication conditions on the traction effect are further considered. Then, the cage flexibility induced by the centrifugal effect is determined by the lumped mass method, and cage clearance deformations are analyzed. On this basis, the dynamic equations are derived by investigating the motions and stress states among the bearing components, and the calculations are compared with experimental data to verify their accuracy and reliability. Finally, the regulatory mechanism of bearing skidding and cage motion stability from the perspective of bearing preload and structural parameters is revealed. The results show that although surface roughness and starved lubrication weaken the lubrication conditions of the ball-race, the traction effect is enhanced to reduce bearing skidding. Compared with the curvature radius of inner race, the groove diameter decreases the cage guiding effect, and ensures cage motion stability by suppressing the collision behavior of the ball-pocket. The system preload is more effective for improving the bearing service performance, which can optimize the collision force of the ball-pocket and increase the cage guiding effect.

INTRAOPERATIVE FASCIAL TRACTION FOR TREATMENT OF W2 AND W3 VENTRAL HERNIAS

Abstract Background Component separation techniques are increasingly employed in abdominal wall reconstruction surgery. The use of adjuvant techniques, such as intraoperative vertical dynamic fascial traction, enhances the compliance of the abdominal wall. This facilitates closure of the abdominal wall using less disruptive techniques without compromising effective treatment. Our aim is to retrospective review our results regarding the effectiveness and complication rate of intraoperative fascial traction for the treatment of complex ventral hernias. Method Conducted a retrospective analysis of 10 patients who underwent surgery using intraoperative fascial traction for W2 and W3 ventral hernias. Results Preoperatively, fascial distances measured ranged from 55 cm to 145 cm, with the majority of patients (70%) having a fascial distance greater than 10 cm. Most patients received other adjuvant treatments (nine cases with botulinum toxin injection and one with pre-operative progressive pneumoperitoneum). Posterior component techniques were employed in 40% of patients (half with W2 hernias and the other half with W3 hernias). The complication rate was 10%, with one case of hemorrhage requiring percutaneous embolization. During the average 6-month follow-up period (ranging from 1 to 17 months), one recurrence was observed. Conclusion Intraoperative fascial traction is a feasible and safe adjuvant technique for abdominal wall reconstruction. The use of adjuvants in complex abdominal wall hernia surgery may, in some patients, downstage the hernia, thereby avoiding the need for component separation techniques. This approach enables tension-free closure of the abdominal wall in a less invasive manner.

Manual traction is effective in alleviating lumbosacral spine pain: Evidence from a randomized controlled trial

BackgroundManual traction, a therapeutic technique frequently employed in healthcare, involves applying controlled pulling force by hand, usually to the spine, to stretch muscles and decompress joints, thereby alleviating pain. This method can be particularly beneficial for addressing lumbosacral spine pain exacerbated by radicular symptoms, characterized by pain radiating from the lower back due to compression or irritation of spinal nerves. PurposeThis study aimed to compare the effects of manual traction against control group in alleviating the lumbosacral spine pain caused by radicular symptoms. MethodsA randomized controlled study design was utilized with a sample of 60 patients experiencing lumbosacral spine pain, evenly distributed between an experimental group (n = 30; receiving manual traction) and a control group (n = 30). Patients underwent assessments before and after six treatment sessions, which included the Straight Leg Raise test, modified Bragard's test, Kernig's test, and the visual analogue scale for pain perception. ResultsBetween-group significant differences were found at post-intervention, favoring the experimental group on SLR – Left (°) (p = 0.004; medium effect size), SLR – Right (°) (p = 0.004; medium effect size), Modified Bragard test – Left (°) (p = 0.024; small effect size), Modified Bragard test – Right (°) (p = 0.003; medium effect size), Kernig's Test – Left (°) (p = 0.013; medium effect size) and Kernig's Test – Right (°) (p = 0.010; medium effect size). Additionally, between-group significant differences were found at post-intervention, favoring the experimental group on VAS scores at SLR left (p < 0.001; medium effect size), and right (p < 0.001); medium effect size, Modified Bragard test left (p < 0.001; medium effect size) and right (p < 0.001; medium effect size) and at Kernig's Test left (p < 0.001; medium effect size) and right (p < 0.001; medium effect size). ConclusionsIn conclusion, manual traction is recommended as an effective approach for alleviating lumbosacral spine pain in patients experiencing symptoms resulting from irritation or compression of a spinal nerve root.

Evaluation of the Effect of Halo Gravity Traction on Lung Volume in Advanced and Severe Kyphoscoliosis Patients in Chest Radiography

Aim: To evaluate the effect of preoperative halo gravity traction on lung volume in patients with advanced and rigid kyphoscoliosis using planimetric measurements from chest radiography. Method: Ten patients with a mean age of 20.5±0.9 with a diagnosis of severe and severe kyphoscoliosis who underwent halo gravity traction between 2019 and 2021 were included in our study. Direct chest radiographs taken before and after traction were analyzed retrospectively. In order to evaluate the effectiveness of traction, planimetric evaluations were made on radiographs. Results: In the evaluation of radiological parameters, mean thoracic coronal cobb angle, lumbar cobb angle, thoracic kyphosis angle, lumbar lordosis angle, C1-S1 distance and lung volume before and after the procedure were 96.670°±8.4535°, 88,090°±4.5989°, 37.020°±11.5893°, 38.540°±11.1269°, 73.150°±7.0412°, 65.590°±7.3927°, 59.100°±9.5467°, 55.100°±9.0238°, It was 371.590mm± 64.2410mm, 408.330 mm±80.8229 mm and 967.730 mm3±318.404 mm3, 1155.180mm3±332.868 mm3. The decrease in thoracic kyphosis, lumbar lordosis, thoracic cobb and lumbar cobb angles and the increase in lung volume and distance between C1-S1 were statistically significant (p&amp;lt;0.05). Conclusion: Traction application is a safe method for deformities. It is effective in correcting sagittal and coronal curvatures. It is a method that is effective in pulmonary functions as well as increasing the lung volume radiologically.
