The change of pain and lumbosacral sagittal alignment after sling exercise therapy for patients with chronic low back pain.

[Purpose] This study was conducted to quantify the effect of sling exercise therapy in the recovery of lumbosacral sagittal alignment (LSA) and in the control of low back pain. [Subjects and Methods] A total of 102 chronic low back pain patients were divided into two groups, a physical therapy group and a sling exercise group. In both groups, programs were conducted thrice a week for twelve weeks. With respect to LSA, pelvic tilt (PT), sacral slope (SS), and pelvic incidence (PI) were measured with plain radiography. Pain was measured on a visual analogue scale (VAS). [Results] Differences were found in visual analogue scale, delta score of visual analogue scale, pelvic tilt, delta score of pelvic tilt, and delta score of pelvic incidence between sling exercise therapy and physical therapy groups. VAS, pelvic tilt, and pelvic incidence was positively changed after sling exercise. However, only the visual analogue scale was found to be improved after physical therapy. [Conclusion] Sling exercise therapy and physical therapy were effective in reducing pain. However, pelvic tilt and pelvic incidence were positively changed after sling exercise therapy for Lumbosacral Sagittal Alignment, but were unchanged after physical therapy. Therefore, sling exercise therapy is more effective than physical therapy for the recovery of Lumbosacral Sagittal Alignment in patients with chronic low back pain.

An analysis on muscle tone and stiffness during sling exercise on static prone position.

[Purpose] The purpose of this study was to examine changes in the muscle tone and stiffness of the lumbar region while individuals adopted the static prone position using sling suspension. [Subjects and Methods] The subjects were 30 healthy women in their 20s. The muscle tone and stiffness of the upper and lower lumbar regions of the sling suspension group and a control group were measured using myotonmetory as they maintained the static prone positon. [Results] The sling suspension group showed statistically significant declines in the muscle tone and stiffness of the upper lumbar region 5–10 min after adopting the initial prone position. They also showed statistically significant declines in the muscle tone and stiffness of the lower lumbar region immediately after being suspended in the slings and a statistically significant decline in the muscle tone of the lower lumbar region 5–10 min after adopting the initial prone position during which the sling suspension was applied. In contrast, the muscle tone and stiffness of the lumbar region of the control group increased while maintaining the static prone position. [Conclusion] The static prone position performed on a treatment table using sling suspension can be an effective intervention for reducing the muscle tone and stiffness of the lumbar region.

Effect of core muscle thickness and static or dynamic balance on prone bridge exercise with sling by shoulder joint angle in healthy adults.

[Purpose] To date, core muscle activity detected using ultrasonography during prone bridge exercises has not been reported. Here we investigated the effects of core muscle thickness and balance on sling exercise efficacy by shoulder joint angle in healthy individuals. [Subjects and Methods] Forty-three healthy university students were enrolled in this study. Ultrasonography thickness of external oblique, internal oblique, and transversus abdominis during sling workouts was investigated. Muscle thickness was measured on ultrasonography imaging before and after the experiment. Dynamic balance was tested using a functional reaching test. Static balance was tested using a Tetrax Interactive Balance System. [Results] Different muscle thicknesses were observed during the prone bridge exercise with the shoulder flexed at 60°, 90° or 120°. Shoulder flexion at 60° and 90° in the prone bridge exercise with a sling generated the greatest thickness of most transversus abdominis muscles. Shoulder flexion at 120° in the prone bridge exercise with a sling generated the greatest thickness of most external oblique muscles. [Conclusion] The results suggest that the prone bridge exercise with shoulder joint angle is an effective method of increasing global and local muscle strength.

The effects of stabilization exercises using a sling and stretching on the range of motion and cervical alignment of straight neck patients.

[Purpose] The purpose of this study was to assess how stretching exercise training and sling exercise training for stabilization influences the cervical spine angles and cervical range of motion of straight neck patients. [Subjects and Methods] Twenty straight neck patients were selected as subjects and they were randomly divided into two groups, the stretching and sling stabilization exercise groups which 60 minutes of exercise three times a week for 6weeks. All the subjects in each of the two respective study groups received an X-ray and had their cervical range of motion measured, both before and after the exercise. [Results] When differences in the cervical spine angle between the pre- and the post-test were checked, it was found that only the stretching exercise group showed statistically significant decreases in the craniovertebral angle and the cranial rotation angle. When differences in the range of motion between pre- and post-test were checked, the sling stabilization exercise group showed a significant change in flexion, right rotation, left lateral bending, right lateral bending, and the stretching exercise group showed a significant change in left rotation, left lateral bending, and right lateral bending. [Conclusion] These results indicate that both types of exercises are effective at improving the cervical range of motion of straight neck patients, and that the stretching exercise was more effective than the sling stabilization exercise at improving cervical spine angles.

Sling Suspension Therapy Utilization in Musculoskeletal Rehabilitation

The development of an effective and inexpensive device to restore and enhance the human musculoskeletal functions is of particular interest. Sling exercise therapy (SET) is one of the most effective developed tools in rehabilitation of musculoskeletal disorders, which has been successfully used in various applications ranging from diagnosis to treatment. To the best of our knowledge, SET has never been comprehended and reviewed previously. Therefore, it was highly required to further understand the role of SET in various therapeutic applications. Inspired by this herein, this study is dedicated to emphasize the advancement in utilization of the SET in both diagnosis and treatment as well as their related challenges. This would be concluded by future perspectives of the SET.

Using ultrasound to assess the thickness of the transversus abdominis in a sling exercise.

BackgroundActivation of the deep stabilizing trunk muscle transversus abdominis (TrA) is important for trunk stabilization and spine stability. Sling exercises are used for the activation of trunk muscles, therefore we determined the thickness of the TrA in a standardized sling exercise in comparison to rest and abdominal press. Furthermore we propose a standardized measurement method, which can be used to compare relative muscle thickness levels in different exercises.MethodsThe main objective of the study was to assess and to compare the thickness of the TrA during different conditions; resting condition, sling exercise condition (non-voluntary contraction), and abdominal press condition (voluntary contraction) using a non-invasive ultrasound-based measurement method.Ultrasound measurement (USM; 8.9 MHz, B-mode) was employed to measure the thickness of the TrA in twenty healthy volunteers (13 m, 7 f), each one measured three times with breaks of 48 h. On each measurement day, the subjects were measured on three different conditions: resting condition (RC), sling condition (SC), and abdominal press condition (APC). The USM images were analyzed using a custom-made MatLab script, to determine the thickness of the TrA.ResultsA two-way repeated-measurements ANOVA was performed with a significant effect of the factor condition [F(2,38) = 47.82, p < 0.0001, η2 = 0.72], no significant effect of the factor time [F(2.38) = 2.45, p = 0.1, η2 = 0.11], and no significant interaction effect [F(4,76) = 0.315, p = 0.867, η2 = 0.02]. Statistically corrected post-hoc t-tests revealed significant differences in TrA thickness showing that RC < SC (p < 0.001; η2 = 0.19; d = 0.96), SC < APC (p < 0.0001; η2 = 0.23; d = 1.10), RC < APC (p < 0.0001; η2 = 0.53; d = 2.11). As for the test-retest reliability the intra-class correlation coefficient (ICC) yielded a value of 0.71, 0.54, and 0.29, on the conditions RC, SC, and APC, respectively.ConclusionsWe showed that the investigated sling exercise can be used to significantly increase the TrA thickness, and that the TrA thickness was significantly different on the three conditions (RC, SC, APC) using the ultrasound-based method.

Comparison of physical function according to the lumbar movement method of stabilizing a patient with chronic low back pain.

[Purpose] The purpose of this study was to examine the changes caused by lumbar stabilization exercises in chronic low back pain patients. [Subjects and Methods] Swiss ball exercise regimen group and sling exercise regimen group exercised for 30 minutes a day, 5 days a week, for 12 weeks. The control group was to continue performing their usual daily living activities. [Results] We obtained significant results in both the Swiss ball and sling exercise groups, but not in the control group. The best effect was obtained in the sling exercise group. [Conclusion] The Oswestry Low Back Pain Disability Index and visual pain scale scores of the patients with low back pain decreased in both the Swiss ball exercise group and the sling exercise group, and these patients experienced an increase in waist isometric muscular strength after 12 weeks of exercise compared with those doing no exercise (the control group).

Isolated Two Non-Displaced Coracoid Fracture Treated with Conservative Means: Report of Two Cases

Coracoid fractures are usually seen with other shoulder injuries. Isolated fractures of this prominence are rare conditions. Herein we present two isolated coracoid fractures after a motorcycle accident and a fall onto the shoulder respectively. Conservative treatment with sling and passive-active shoulder exercises is accepted approach in these fractures. We also prefer conservative treatment at our cases and both of them have good results.

The effect of six weeks of sling exercise training on trunk muscular strength and endurance for clients with low back pain.

[Purpose] The purpose of this study was to investigate the effects of 6 weeks sling exercise training for clients with low back pain on the levels of pain, disability, muscular strength and endurance. [Subjects and Methods] Twelve chronic LBP subjects participated in this study. Subjects were randomly divided into a control group and a training group. Subjects in the training group performed sling exercise training for six weeks, and participants in the control group did not perform any exercise. [Results] Pain, disability levels and muscular strength significantly improved in the training group, but not in the control group. The left multifidus showed a significant improvement in muscular endurance, measured as the slope of the median frequency after training. [Conclusion] Six weeks of sling exercise training was effective at reducing pain intensity, and improving the disability level and trunk muscular strength of subjects with low back pain.

The effects of respiratory muscle strengthening exercise using a sling on the amount of respiration.

[Purpose] The purpose of this study was to present aerobic exercise that can be performed together with respiratory muscle strength training and examine whether the vital capacity of individuals can be enhanced when respiratory muscle strength training is conducted together with aerobic exercise. [Subjects and Methods] The subjects were 10 male students and 8 female students. The sling exercise method was used to conduct three types of training to strengthen the muscles around the shoulder joints. A maximal respiratory quotient measurement device was used to measure the vital capacity of the subjects five times. [Results] There was a significant difference in each respiratory training time point compared with before the performance of respiratory training. [Conclusion] This study presented respiratory muscle strength training using a sling as a training method for respiratory training.

Comparison of Abdominal Muscle Activity after Sling and Swiss-ball Exercises in Asymptomatic Adults

【PURPOSE: The purpose of this study was to investigate any changes in abdominal muscle activity after curl-up and jack-knife exercisse using a sling and swiss-ball. METHODS: Sixteen asymptomatic subjects were randomly assigned into either a sling exercise group (SG) or swiss-ball exercise group (SBG). Subjects performed curl-up and jack-knife exercise using sling and swiss ball. Activity of abdominal muscles (rectus abdominis and external oblique) was assessed using surface electromyography (EMG) and normalized maximal voluntary isometric contraction (MVIC) before and after exercises. The significance of differences between the SG and the SBG was evaluated by analysis of covariance (ANCOVA). RESULTS: There was an increase in activity of all abdominal muscles after the curl-up and jack-knife exercises for 6 weeks. However, there was not a significant difference between the SG and the SBG after curl-up exercise (p>.05). There was also not a significant difference between the SG and the SBG after Jack-knife exercise (p>.05) except for the right external oblique muscle (p】

Sling Exercise for Chronic Low Back Pain: A Systematic Review and Meta-Analysis

BackgroundTrials on sling exercise (SE), commonly performed to manage chronic low back pain (LBP), yield conflicting results. This study aimed to review the effects of SE on chronic LBP.MethodsThe randomized controlled trials comparing SE with other treatments or no treatment, published up to August 2013, were identified by electronic searches. Primary outcomes were pain, function, and return to work. The weighted mean difference (WMD) and 95% confidence interval (CI) were calculated, using a random-effects model.ResultsRisk of bias was rated as high in 9 included trials, where some important quality components such as blinding were absent and sample sizes were generally small. We found no clinically relevant differences in pain or function between SE and other forms of exercise, traditional Chinese medical therapy, or in addition to acupuncture. Based on two trials, SE was more effective than thermomagnetic therapy at reducing pain (short-term: WMD –13.90, 95% CI –22.19 to –5.62; long-term: WMD –26.20, 95% CI –31.32 to –21.08) and improving function (short-term: WMD –10.54, 95% CI –14.32 to –6.75; long-term: WMD –25.75, 95% CI –30.79 to –20.71). In one trial we found statistically significant differences between SE and physical agents combined with drug therapy (meloxicam combined with eperisone hydrochloride) but of borderline clinical relevance for pain (short-term: WMD –15.00, 95% CI –19.64 to −10.36) and function (short-term: WMD −10.00; 95% CI −13.70 to −6.30). There was substantial heterogeneity among the two trials comparing SE and thermomagnetic therapy; both these trials and the trial comparing SE with physical agents combined with drug therapy had serious methodological limitations.InterpretationBased on limited evidence from 2 trials, SE was more effective for LBP than thermomagnetic therapy. Clinically relevant differences in effects between SE and other forms of exercise, physical agents combined with drug therapy, traditional Chinese medical therapy, or in addition to acupuncture could not be found. More high-quality randomized trials on the topic are warranted.

슈로스(Schroth)운동치료와 슬링운동치료가 척추측만증 환자의 유연성, 균형능력, 척추각 및 흉곽 확장에 미치는 효과 비교

The subjects were 16 patients who were diagnosed with scoliosis. They were randomly assigned either to a Schroth exercise group (n=8) that received Schroth exercise program or to a sling exercise group (n=8) that received sling exercise program. Flexibility, static balance, dynamic balance, and spinal angles were measured by using the modified sit and reach test, one leg standing with closed eyes, functional reach test, and Cobb’s angle, respectively. The chest expansion were calculated using differences of chest circumference between maximum inspiration and maximum expiration measured under armpits, at the junction between the sternum and xiphoid process, and at the waist.

New aspects of physical therapy for osteoporosis

SummaryFractures due to osteoporosis are among the leading causes of functional limitation, chronic pain, and greater morbidity in advanced age. Apart from bone, risk factors for osteoporotic fractures include non-osseous causes such as falls or reduced neuromuscular capacity. Muscle and coordination exercises enhance the patient’s abilities in daily life and prevent falls. In view of recent conclusions drawn from competitive sports, which stress the significance of muscles of the trunk with regard to reducing back pain and optimizing posture, we used sling exercises to determine whether they benefit patients with osteoporosis and are more useful than traditional physiotherapy. A stable ceiling construction was installed for sling exercise; slings were suspended from this construction. Fifty patients were randomized into two groups. Group A received traditional physiotherapy while group B was given sling exercises, in each case twice a week for a period of three months. The exercises were similar in the two groups. Both performed chair-rising exercises and pelvic lift in supine position; the sling exercise group used the slings for this purpose. The results of treatment (pre-post) were analyzed in terms of pain levels, mobility, trunk strength, and the shape of the back. For the latter we used the spine scanner Diers®Formetric 4D to measure the spine surface of the patients with low radiation. After a further three months with no specific exercise treatment, we re-tested the patients to establish the long-term effects of the two types of exercises. Forty-four patients (88 %) completed the study. Patients were assigned to small groups for the exercises (a maximum of 5 patients each), and thus received individual attention and motivation. Positive training effects were achieved in both groups. Significantly better results in regard of improved mobility (8.2 ± 1.9 vs. 6.7 ± 1.4; p = 0.005) and pain at rest (3.1 ± 1.7 vs. 1.9 ± 1.4; p = 0.011) were registered in the sling exercise group. A comparison of the baseline values for these parameters to those reported at follow-up, without specific stabilization or strengthening exercises, it was found that the effect lasted for a minimum period of 3 months (p &lt; 0.001). The results of the investigation confirm the known positive effects of physical therapy with regard to back pain in patients with osteoporosis. Simultaneously, sling exercise proved to be a treatment alternative that improves trunk strength and posture as well as provides greater mobility, thus improving quality of life in patients with osteoporosis.

Effectiveness of sling exercise for chronic low back pain: a systematic review.

[Purpose] This study investigated effects of sling exercise for patients with chronic low back pain. [Methods] We reviewed all relevant papers indexed in PubMed, SCOPUS, and the Cochrane Registered Trials. Eligible trials were randomized controlled trials that compared sling exercise with any type of treatment. We extracted data on muscle thickness, muscle activation, pain, and disability, and assessed the methodological quality of the data. Seven studies met our inclusion criteria. [Results] When sling exercise had an impact on activation of the trunk muscles, increasing the trunk muscle thickness, and the reduction in pain and disability had been assessed shortly after the final exercise session, it was more effective than general exercise at activating trunk muscles, but not more effective at increasing trunk muscle thickness and improving pain and disability than general exercise. [Conclusion] As sling therapy studies are based on a small number of trials, we cannot draw conclusions about the therapeutic effects of sling exercise. When segmental stabilizing exercise and individually designed programs are added to sling exercise, it increases the effectiveness of sling exercise at improving low back pain. This should be the focus of future studies.

The effect of continuous passive motion and sling exercise training on clinical and functional outcomes following total knee arthroplasty: a randomized active-controlled clinical study.

BackgroundThe parallel-group randomized active-controlled clinical study was conducted to compare the effectiveness of two in-hospital range of motion (ROM) exercise programs following total knee arthroplasty (TKA). Continuous passive motion (CPM) is frequently used to increase ROM and improve postoperative recovery despite little conclusive scientific evidence. In contrast, a new active sling-based ROM therapy requires the activation of the knee joint muscles and dynamic joint stabilization. It was hypothesized that higher demands on muscle strength and muscle coordination during sling exercise training (ST) might be advantageous for early recovery following TKA.MethodsA total of 125 patients undergoing primary TKA were assessed for eligibility. Thirty-eight patients were randomly assigned to receive ST or CPM (control intervention) during hospital stay. Patients were assessed before TKA for baseline measurement (pretest), 1 day before discharge (posttest) and 3 months after TKA (follow-up). The passive knee flexion range of motion (pFL) was the primary outcome measure. Secondary outcome measures included active knee flexion range of motion, active and passive knee extension ROM, static postural control, physical activity, pain, length of hospital stay as well as clinical, functional and quality-of-life outcomes (SF-36, HSS and WOMAC scores). Data were analyzed according to the intention-to-treat principle. Differences between the groups were tested for significance by the unpaired Student’s t test or an analysis of covariance (ANCOVA) adjusted for baseline, weight, sex, age, pain and physical activity.ResultsA between-group difference could be determined at posttest. The pFL was significantly higher by 6.0° (95% CI 0.9 to 11.2°; P = 0.022) in the ST group. No difference between groups in pFL was documented at follow-up. Furthermore, no significant differences could be observed for any secondary outcome measure at posttest and follow-up.ConclusionsST seems to have a clinically relevant beneficial short-term effect on pFL compared to CPM. The results support the implementation of ST in rehabilitation programs following TKA.Level of evidenceTherapy, level 2b
