Abstract: BACKGROUND: Exercise training after lumbar fusion surgery (LFS) is important for regaining the strength in the spinal muscles, pain management, and minimizing dysfunction. It may be prudent to evaluate technologies such as web-based chat and social media apps for increasing the efficacy of post-surgery interventions in LFS patients. OBJECTIVE: To explore the effectiveness of a WeChat-based individualized post-discharge rehabilitation program in patients with LFS. METHODS: Seventy-two eligible discharged LFS patients were enrolled from October 2018 to February 2019. The experimental group (36 cases) received a 10-week WeChat-based individualized rehabilitation program, while the control …group (36 cases) received routine follow-up guidance. The outcomes were measured using the Exercise Compliance Questionnaire, Numerical Rating Scale, Oswestry Disability Index and Chinese version of the self-efficacy for exercise scale. RESULTS: The analysis using generalized estimation equations method shows significant differences in the interaction effect of group*time in exercise compliance (Wald c 2 = 7.459, P < 0.05), group effect in pain (Wald c 2 = 5.811, P < 0.05) and self-efficacy (Wald c 2 = 16.383, P < 0.05). However, there was no significant difference between the experimental and control groups in the group effect in dysfunction improvement (Wald c 2 = 2.289, P > 0.05). CONCLUSIONS: The WeChat-based rehabilitation intervention can improve exercise compliance and self-efficacy, and help achieve greater pain relief compared to the routine intervention. However, the WeChat-based intervention did not offer better improvement in the self-dysfunction in the post-discharge LFS patients. Show more

Abstract: BACKGROUND: Facet joint syndrome (FJS) pain is a significant contributor to back pain and has a high rate of opioid prescription. Unfortunately, there are a limited number of therapeutic options for these patients. OBJECTIVE: To evaluate the safety and effectiveness of amniotic membrane/umbilical cord particulate (AM/UC) in managing FJS pain. METHODS: A single-center, investigator-initiated, retrospective study was performed on consecutive patients with FJS pain who received intra- or peri-articular injection of AM/UC between July 1, 2018 and July 26, 2019. Primary outcome was change in Patient Global Impression of Change (PGIC) at 6 …weeks, 3 months, 6 months, and 12 months to assess the self-reported percent improvement relative to baseline. Safety was assessed by AM/UC- and procedure-related complications. Paired t -tests were used to determine whether there is a statistically significant improvement of pain post-injection compared to baseline. RESULTS: There were a total of 54 patients (69.7 ± 13.4 years; 31 female) presenting baseline pain score of 9.2 ± 1.0 despite prior treatments of activity modification (66.7%), NSAIDs (61.1%), opioids (37.0%), and physical therapy (35.2%). Mean GPIC improvement was 65.3%, 67.5%, 56.9%, and 56.7% among responders 30 , respectively. There were no complications. CONCLUSION: This study supports the safety and effectiveness of AM/UC particulate injection in managing FJS pain. Show more

Abstract: BACKGROUND: Knee osteoarthritis (OA) impairs postural control and may affect how the lower limb joints are used for postural control. OBJECTIVE: To investigate how individuals with knee OA use lower limb joints for static postural control. METHODS: Ten patients with knee OA and thirteen healthy controls performed quiet standing for 30 s. The standard deviation of the center of mass (COM) and lower limb joint motions in the anterior-posterior (AP) and medial-lateral (ML) planes were calculated from three-dimensional marker trajectories. Pearson’s correlation analysis and independent t -tests were conducted to investigate the relationship between …COM and lower limb joint motion and to compare group difference, respectively. RESULTS: The AP hip angular velocity alone in the knee OA group and the AP hip and knee angular velocity in the control group were significantly correlated with the AP COM velocity. The ML hip angular velocity was significantly correlated with the ML COM velocity in both groups. The knee OA group exhibited a significantly larger standard deviation of AP COM velocity than the control group. CONCLUSIONS: Individuals with knee OA depended solely on the contribution of the hip to the AP COM velocity, which could not be successfully controlled by the knee. Show more

Abstract: BACKGROUND: Adolescents with idiopathic scoliosis present postural instability when compared with healthy subjects. Although Schroth exercises therapy (SET) is broadly utilized, its effect on postural stability is still not clear. OBJECTIVES: To compare the two treatment periods of the SET for improving the postural stability indices and Cobb angle, and to examine the correlation between the Cobb angle and stability indices in adolescent idiopathic scoliosis (AIS). METHODS: Twenty girls aged 10–16 years with AIS (study group) and 20 age-matched girls without AIS (control group) were examined. The Biodex Balance System was used to …evaluate the overall stability index (OSI), anteroposterior index (APSI), and mediolateral stability index (MLSI) in the study group before SET and one and three months after the therapy. A plain X-ray was used to measure the Cobb angle before and three months after SET. Stability indices and Cobb angle were measured only once for the control group. RESULTS: One-way repeated-measures ANOVA revealed that the three-month duration of SET was the most effective for improving OSI, APSI, and MLSI (p < 0.001). The significant proximities of OSI, APSI, and MLSI to the normal values post three months of SET were 29.65%, 24.07, and 20% respectively. The MLSI was robust and correlated with the Cobb angle (r = 0.85) three months post intervention. CONCLUSION: Stability indices and Cobb angles were highly improved after three months of SET compared to one month among AIS patients. The MLSI is the most substantial index correlated with the Cobb angle. Show more

Abstract: BACKGROUND: Many patients complain of chronic cervical radicular pain, and pulsed radiofrequency (PRF) is known to have a positive effect for alleviating neuropathic pain. OBJECTIVES: In the present study, we used ultrasound (US) guidance and compared the effects of monopolar PRF with those of bipolar PRF in patients with chronic cervical radicular pain refractory to repeated transforaminal epidural steroid injections. METHODS: Sixty-six patients with chronic cervical radicular pain were included in this study. Patients were randomly assigned to one of the two groups: monopolar or bipolar PRF group (n = …33 per group). Pain intensity was evaluated using a numeric rating scale (NRS) at pretreatment, and at 1 and 3 months after the treatment. Target stimulation site was the extraforaminal nerve root. RESULTS: Compared to the pretreatment NRS scores, patients in both groups showed a significant decrease in NRS scores at 1 and 3 months after the treatment. Reductions in the NRS scores over time were significantly larger in the bipolar PRF group. Three months after the treatment, 18 patients (54.5%) in the monopolar PRF group and 27 (81.8%) in the bipolar PRF group reported successful pain relief (pain relief of ⩾ 50%). CONCLUSIONS: US-guided PRF can be an effective interventional technique for the management of chronic refractory cervical radiculopathy. Moreover, bipolar PRF has better treatment outcome than monopolar PRF. Show more

Abstract: BACKGROUND: Abdominal bracing is effective in strengthening the trunk muscles; however, assessing performance can be challenging. We created a device for performing abdominal trunk muscle exercises. The effectiveness of this device has not yet been evaluated or compared OBJECTIVE: We aimed to quantify muscle activity levels during exercise using our innovative device and to compare them with muscle activation during abdominal bracing maneuvers. METHODS: This study included 10 men who performed abdominal bracing exercises and exercises using our device. We measured surface electromyogram (EMG) activities of the rectus abdominis (RA), external oblique, internal oblique …(IO), and erector spinae (ES) muscles in each of the exercises. The EMG data were normalized to those recorded during maximal voluntary contraction (%EMGmax). RESULTS: During the bracing exercise, the %EMGmax of IO was significantly higher than that of RA and ES (p < 0.05), whereas during the exercises using the device, the %EMGmax of IO was significantly higher than that of ES (p < 0.05). No significant difference was observed in the %EMGmax of any muscle between bracing exercises and the exercises using the device (p = 0.13–0.95). CONCLUSIONS: The use of our innovative device results in comparable activation to that observed during abdominal bracing. Show more

Abstract: BACKGROUND: Cervicogenic headache (CGH) is a common condition that results in significant disability. To treat this dysfunction, Mulligan described sustained natural apophyseal glides (SNAGs) as a manual therapy approach. However, only inconclusive short-term evidence exists for treating CGH with SNAGs. OBJECTIVE: The present study aims to investigate the effect of SNAGs in the treatment of CGH. METHODS: Fourty female patients ranging from 20 to 40 years with CGH were randomly assigned to two groups: 20 in a treatment group and 20 in a control group. SNAGs were applied to the treatment group while …the control group received placebo treatment. Both groups received their respective treatment for 20 minutes, alternately three times per week, for a total of 12 times in four weeks. The outcome measures were the Neck Disability Index (NDI) and the Visual Analogue Scale (VAS). Participants were assessed at baseline and at the end of each week. The data was analyzed using SPSS version 20. Independent t-testing was used to reveal changes between groups. One-way ANOVA was used to determine changes within groups. The level of significance was P < 0.05. RESULTS: Twenty participants (100%) in the treatment group and 17 (85%) in the control group had a history of headache aggravation with active movements or passive head positioning. There was no significant difference at baseline (p > 0.05), indicating that both groups were homogeneous at the time of recruitment. The p value (p < 0.05) showed a significant difference in pain and level of disability at three and four weeks (p < 0.05) in patients treated with SNAGs. However, the cervical range of motion (ROM) showed a statistically significant improvement in flexion and extension in the treatment group (p < 0.05) while there was no significant improvement in side flexion and rotation ROM in both groups (p > 0.05). CONCLUSION: This study found that SNAGs were effective in reducing pain and neck disability and improved ROM in females with CGH. Show more

Abstract: BACKGROUND: Given the characteristics of the superficial trunk muscles that cross the chest and pelvis, their excessive contraction might limit chest mobility. OBJECTIVE: To examine the immediate effects of two types of trunk muscle exercises on chest mobility and trunk muscle activities. METHODS: Fourteen healthy men (age: 21.1 ± 1.0 years, height: 172.7 ± 5.6 cm, weight: 61.0 ± 7.1 kg, body mass index: 20.4 ± 1.7 kg/m 2 ; mean ± SD) randomly performed …trunk side flexion and draw-in exercises using a cross-over design. The chest kinematic data and trunk muscle activities were measured before and after each intervention during the following tasks: maximum inspiration/expiration and maximum pelvic anterior/posterior tilt while standing. Two-way repeated measures analysis of variance was used for statistical analysis (P < 0.05). RESULTS: After the side flexion, upper and lower chest mobility significantly decreased, and superficial trunk muscle activity significantly increased during the maximum pelvic anterior tilt (P < 0.05). Additionally, after the draw-in, upper chest mobility significantly increased during the maximum pelvic anterior tilt (P < 0.05). CONCLUSIONS: Increased activity of the superficial abdominal muscles might limit chest mobility during maximum pelvic anterior tilt. Conversely, the facilitation of deep trunk muscles might increase upper chest mobility during the maximum pelvic anterior tilt. Show more

Abstract: BACKGROUND: Although there are a few studies on the seasonality of facial paralysis, no studies have utilized internet data for this purpose. The use of internet data to investigate diseases and user-contributed health-related content is increasingly prevalent, and has earned the name “infodemiology”. OBJECTIVE: This study aims to use Google Trends data to investigate whether there is a seasonal variation in facial paralysis. METHODS: In this observational study, the search volume for the terms “facial paralysis” and “Bell’s palsy” for a total of 19 countries was queried from Google Trends, selecting the time …interval between January 2004 and October 2020. RESULTS: In the Cosinor analysis of data from a total of 19 countries, from both northern and southern hemisphere, a statistically significant seasonality was found in the search volume of facial paralysis. It was observed that facial paralysis searches peaked in spring in the northern hemisphere and in winter in the southern hemisphere. CONCLUSION: Internet search query data showed that facial paralysis has a seasonal variation, with peaks in spring for the northern hemisphere and winter for the southern hemisphere. Further studies are needed to understand the deviation between hemispheres and the cause of the peak in winter-spring season. Show more

Abstract: BACKGROUND: Worldwide, chronic low back pain (CLBP) is one of the most common causes of physical and psychological disabilities. The factors that affect low back pain (LBP) between Western and Eastern countries are different. OBJECTIVE: We assessed the factors associated with LBP and their impact in German and Thai CLBP participants. METHODS: This cross-sectional study was conducted in 100 Thai and 100 German CLBP participants. Data were collected before the participants received treatment in the outpatient rehabilitation clinic. We used standardized questionnaires to assess the demographic and socioeconomic data, clinical features of the …pain, the impact of pain during daily activities, and psychological consequences. RESULTS: We found a statistically significant difference between the two groups for minimal pain intensity (NRS German = 3.01, Thai = 1.83), and the participants’ acceptable pain intensity (NRS German = 1.97, Thai = 3.88). The German participants had a higher negative impact score in their daily living compared to the Thai participants (German = 23.5, Thai = 10). Also, the German participants suffered more often from depression (CES-D score; German = 17, Thai = 4). However, the average back pain intensity was the same for both groups. CONCLUSION: German CLBP participants had significantly more depressive symptoms and pain-related impairments compared to the Thai participants. On the other hand, there were no differences in maximum and average pain severities. Show more

Abstract: BACKGROUND: Piriformis syndrome (PS) is the common entrapment neuropathy causing buttock pain. Patients are conventionally treated with lifestyle modification, exercise, non-steroidal anti-inflammatory drugs, corticosteroid or botulinum toxin injections. However, some patients may not respond to these conventional treatment methods. Platelet rich plasma (PRP) injection has been shown to be beneficial in various muscular injuries, but its effects have not yet been investigated in PS. OBJECTIVE: The aim of this study was to explore the effect of PRP on pain and functional status in patients with PS, and to identify any correlations between clinical changes and demographic …features. METHODS: A total of 60 patients with PS were randomly separated into two groups (PRP and control groups). All patients received one session of either PRP or saline injection performed under ultrasound guidance. The pain was measured with a visual analog scale (VAS) and Oswestry Disability Index (ODI) scores were noted at three intervals in both groups: before treatment, 1 week after treatment and 1 month after treatment. RESULTS: The VAS and ODI scores were improved in both groups. The improvement was more obvious in the PRP group in the first week, and the results were similar for both groups when measured 1 month after the treatment. CONCLUSION: Ultrasound-guided PRP injection provided greater improvements in both pain and functional status in patients with PS, starting in the early period after treatment. A repeat injection might be needed for a long-term effect. Show more

Abstract: BACKGROUND: Low back pain (LBP) causes disability in daily life, and presents not only a health but also a socio-economic problem. New treatment options need to be tested and confirmed. OBJECTIVE: Compare the effect of the McKenzie method and spiral stabilization in patients with LBP. METHODS: Sixty patients with an average age of 47 years, which were included in our prospective, comparative study were randomly divided into two 30-member groups. One group exercised according to the McKenzie method (MDT), the other one according to the Spiral Stabilization Method (SPS). During the initial examination the …Aberdeen Back Pain Scale was used to determine the degree of managing with daily activities and functionality, and the Roland-Morris Disability Questionnaire was used to determine the degree of disability. Check- up was performed after 2 and 6 weeks of treatment. RESULTS: In both groups, there was a significant improvement in results after 2 and 6 weeks of treatment (p < 0.05). When comparing the effect of 2 and 6 weeks of treatment of both therapeutic procedures (MDT and SPS), the difference was insignificant (p > 0.05). CONCLUSIONS: None of these two treatment methods achieved better results, as they both have a comparable effect on reducing disability and improving the management of daily activities and physical functions. Therefore, both are equally effective in patients with LBP. Show more

Abstract: BACKGROUND: Flexible flatfoot is associated with altered plantar pressure distribution, but it is not clear how muscle fatigue affects plantar pressure characteristics in flexible flatfoot and normal foot. OBJECTIVE: To investigate the effects of calf muscles fatigue on plantar pressure variables in flexible flatfoot and normal foot. METHODS: Twenty-five people with flexible flatfoot and twenty-five people with normal foot were included. The unilateral heel-rise test was used to induce calf muscles fatigue. Plantar pressure variables were collected during preferred walking immediately before and after fatigue. The two-way mixed-design ANOVA was used to determine …the main effect of fatigue and the interaction between foot posture and fatigue. RESULTS: Fatigue caused medialization of the contact area under the forefoot and the maximum force under the heel and forefoot (p < 0.05). When examining the differences in the effects of fatigue between groups, the contact area under the medial heel increased with fatigue in flexible flatfoot but decreased in normal foot; moreover, the contact area and maximum force under the midfoot and the maximum force under the third metatarsal decreased with fatigue in flexible flatfoot but increased in normal foot (p < 0.05). CONCLUSIONS: Calf muscles fatigue caused medialization of the maximum force and contact area. Especially the midfoot was affected differently by fatigue in flexible flatfoot and normal foot.

Abstract: BACKGROUND: In order to administer the International Knee Documentation Committee Subjective Knee Form (IKDC) questionnaire to Arabic speakers, a rigorous process of cross-cultural adaptation and validation is required in order to reach equivalence between the original publication and target version of the questionnaire. OBJECTIVES: The main aim of this study is to translate and culturally adapt the IKDC into Arabic to suit the Arabic population. The secondary aim is to assess the Arabic version of the IKDC in order to test the psychometric characteristics (reliability, validity and dimensionality). METHODS: The translation process has …been carried out according to cross-cultural adaptation guidelines in accordance with the American Orthopaedic Society for Sports Medicine guidelines with forward/backward translations and pre-testing. The Arabic IKDC, Knee injury and Osteoarthritis Outcome Score (KOOS), RAND-36-Item Health Survey (RAND-36) questionnaire, and visual analogue scales (VAS) of pain were tested in 105 ACLR patients. Test-retest reliability, internal consistency, construct validity and content validity were evaluated. RESULTS: The test-retest reliability proved excellent with a high value for the intraclass correlation coefficient (r = 0.95). The internal consistency was strong (Cronbach’s α = 0.91). Good construct validity by the strong correlations between similar component of the KOOS subscales, Rand-36 subscales and VAS, and good content validity with absence of floor and ceiling effects. CONCLUSIONS: The Arabic version of the IKDC is a valid and reliable instrument for Arabic patients with ACLR. However, further research is required with a more varied knee sample in order to enable generalisation to a wider population. Show more

Abstract: BACKGROUND: The gold standard in the clinical assessment of the extent of scoliosis is the Cobb method but the analysis also covers the changes that occur within the spine and trunk in relation to the transverse and sagittal planes. OBJECTIVE: The study aimed to estimate changes in the sagittal plane of the spine in girls with right-sided thoracic adolescent idiopathic scoliosis. METHODS: The study involved 29 girls with scoliosis (13.6 ± 0.6 years) and 36 healthy girls as the comparison group. The tests included an interview, clinical examination (with the …use of Adam’s test and the Cobb angle), and examination of shape of the spine surface with the use of the photogrammetric method and the projection moire effect. RESULTS: Lower values of the thoracic kyphosis parameters were found in the scoliosis group. Significant differences were noted for the parameters of the lumbosacral section α (p = 0.02), thoracolumbar section β (p < 0.001), the upper thoracic section γ (p < 0.001), thoracolumbar and upper thoracic section β + γ (p < 0.001) and the total size of α + β + γ (p < 0.001) curvatures. CONCLUSIONS: The study showed that with an increase in the angular value of the thoracic curvature, the thoracic kyphosis decreased. Show more

Abstract: BACKGROUND: Scoliosis causes changes in the thorax, but it is unclear what type of changes occur in the thoracic profile after scoliosis surgery. OBJECTIVE: To investigate changes in rib cage deviation in the postoperative period after adolescent idiopathic scoliosis (AIS) surgery. METHODS: Forty-four patients with AIS with a main right thoracic curvature underwent posterior surgical fusion (PSF), and radiological parameters of the spine and thorax were evaluated. RESULTS: The correction rates of main thoracic curve (MT)-Cobb angle at immediate after surgery and postoperative follow-up (2 years) were 64% and 66%, …respectively. At these two postoperative time points, the correction rates of height of thoracic vertebrae 1 to 12 (T1T12) were 10% and 12%; the correction rates of Rib-vertebra angle difference (RVAD) were 59% and 52%; the correction rates of Apical rib hump prominence (RH) were 58% and 76%; while the correction rates of Apical vertebral body-rib ratio (AVB-R) were 23% and 25%, respectively. Statistical analysis showed that all these radiological parameters at the two postoperative time points were significantly different from the preoperative values (p < 0.001). There were significant correlations between MT-Cobb angle and T1-T12 height (p < 0.001), RVAD (p < 0.001), RH (p < 0.001), and AVB-R (p < 0.001). CONCLUSIONS: Posterior spinal fusion appears to be effective at correcting scoliosis, and the correction of rib cage deviation also plays an important role. Show more
