Effects of telerehabilitation-based respiratory and corrective exercises among the elderly with thoracic hyper-kyphosis: a clinical trial.

BACKGROUND: Aging is associated with changes in the musculoskeletal system, including increased susceptibility to spine malalignments. Utilizing corrective exercises with a therapeutic emphasis can be beneficial in the elderly with thoracic spine hyperkyphosis. OBJECTIVE: This study aimed to investigate the effects of six weeks of telerehabilitation-based respiratory and corrective exercises on quality of life, disability, thoracic kyphosis, craniovertebral angle, shoulder angle, cranial angle, and chest expansion in the elderly with thoracic spine hyperkyphosis. METHODS: In this clinical trial, a total of 40 participants aged 60 and above with thoracic hyperkyphosis were randomly divided into the control (N = 20) and experimental (N = 20) groups. The experimental group performed the corrective exercises for six weeks (3 sessions per week). The control group performed general stretching exercises during the same time period. We measured the outcomes of quality of life, disability, thoracic kyphosis, craniovertebral angle, shoulder angle, cranial angle, and lung expansion before and after the intervention. Analysis of covariance (ANCOVA) was employed to analyze the data. A P-value ≤ 0.05 was considered statistically significant. RESULTS: Quality of life (P < 0.001, Effect Size (ES): 0.44), chest expansion (P < 0.001, ES: 0.56), thoracic kyphosis angle (P < 0.001, ES: 0.31), craniovertebral (P < 0.001, ES: 0.33), cranial (P < 0.001, ES: 0.38), and shoulder (P = 0.005, ES: 0.20) angles were significantly improved in the experimental group as compared with controls. However, no statistically significant difference was observed between the two groups in terms of physical ability (P = 0.251, ES: 0.04). CONCLUSION: It is therefore recommended that online corrective exercises be used in the rehabilitation protocol to improve the quality of life, posture, chest expansion, and disability in the elderly with thoracic kyphosis.

An affordable and immersive virtual reality-based exercise therapy in forward head posture.

Forward Head Posture (FHP) is one of the most commonly occurring musculoskeletal abnormalities. Despite exercise therapy being an effective approach for FHP treatment, it can be long, monotonous, and tedious. Virtual reality (VR) can be used as an innovative solution to address these challenges. We designed an affordable and immersive VR-based exercise therapy (VRET) system for FHP correction. The VRET contents (i.e., exercises and VR scenarios) were determined by physiotherapists and game designers at the focus group meetings. Hardware requirements include a VR box, smartphone, and sensors (i.e., a smartphone accelerometer and an affordable Inertial Measurement Unit (IMU)) to measure head motions and transfer them via Wi-Fi to the VRET system. The IMU was designed using the MPU6050, Arduino Nano, and ESP8266-01S. Gwet's AC1, Game Experience Questionnaires (GEQ), and System Usability Scale (SUS) were used to measure intra-rater reliability, user experience, and system usability, respectively. The determined exercises, including Capital Flexion-Extension and Chin Tuck, were designed in the form of a shooting game. A physiotherapist and twenty-one FHP individuals took part in evaluating the system. High precision was obtained for the designed IMU (i.e., pitch and roll < 0.1° and yaw < 1.3 °). Gwet's AC1 and SUS results showed very good intra-rater reliability (coefficient = 0.892) and excellent usability (score = 87.14), respectively. According to the mean scores of the GEQ, participants were confident about competence, immersion, flow, and positive affect components. The development of low-cost VRET systems for FHP correction is a step towards facilitating rehabilitation challenges by providing positive experiences for users as well as helping them perform therapeutic exercises correctly.

Oswestry Disability Index, Roland-Morris Disability Questionnaire, and Quebec Back Pain Disability Scale: Responsiveness and Minimal Clinically Important Changes in Iranian People with Lumbar Disc Herniation Following Physiotherapy.

Objectives: The present study aimed to investigate the responsiveness of the Persian version of the Oswestry Disability Index (ODI), Roland-Morris Disability Questionnaire (RMDQ), and Quebec Back Pain Disability Scale (QBPDS) and detect minimal clinically important changes (MCICs) of these questionnaires in people with lumbar disc herniation. Methods: Ninety-two patients with lumbar herniated disc completed the Persianversion of the ODI, RMDQ, and QBPDS before and after the physiotherapy intervention. Additionally, they completed a global rating of change scale after the final physiotherapy session to give an account of non-improved and improved outcomes. The responsiveness of these three disability questionnaires was represented by Receiver Operating Characteristic (ROC) and correlation analyses. The MCIC was defined as the best cut-off when sensitivity and specificity were optimally balanced. Results: Area under the ROC curves are in the acceptable range for ODI and QBPDS (0.78 and 0.70, respectively). Moreover, ODI, RMDQ, and QBPDS have significant positive fair to moderate correlation with the external anchor (P<0.001). The MCIC values for ODI, RMDQ, and QBPDS were 13, 5.5, and 14.5 points, respectively. Conclusion: Our results revealed that the ODI and QBPDS questionnaires have adequate responsiveness to detect improvements in the functional status of lumbar herniated disc patients following a physiotherapy treatment. Therefore, the ODI and QBPDS seem to be superior to the RMDQ for use in randomized clinical trials and clinical settings in patients with herniated lumbar discs. The MCIC scores of 13 and 14.5 obtained for the ODI and QBPDS can help to identify important changes in the clinical status of an individual patient and treatment efficacy.

The effect of a childbirth preparation program including posture correction and stretching movements on lordosis and lumbar pain.

AIM: The study aimed at evaluating the effect of posture correction and stretching movements on lordosis and lumbar pain in pregnant women. BACKGROUND: An increased lumbar lordosis during pregnancy is considered one of the most common causes of lumbar pain. METHODS: This quasi-experimental study was performed on 66 pregnant women referred to health centers in Tabriz, Iran, from November 2020 to June 2021. The participants were randomly assigned to the intervention and control groups. The intervention group received training of posture correction movements and stretching exercises during pregnancy from 16 to 18 to 35-37 weeks of pregnancy in six sessions for 45-60 min. The data were collected using a flexible ruler and a visual analog scale. Independent t-tests, repeated measures ANOVA, and ANCOVA tests were used. RESULTS: The mean (standard deviation: SD) of lumbar lordosis increased from 45.12 (2.07) to 54.97 (2.20) in the intervention group at 35-37 weeks and changed from 44.28 (2.03) to 55.54 (3.39) in the control group at 35-37 weeks (adjusted mean difference: -1.24, 95% confidence interval: -2.48 to -0.005, P = 0.04). The mean (SD) of lumbar pain at 28-30 weeks was 2.80 (1.72) in the intervention group and 3.74 (2.23) in the control group (P = 0.09). However, the mean (SD) of lumbar pain at 35-37 weeks in the intervention group 4.38 (2.45) was significantly lower than that in the control group 5.83 (2.96) (P = 0.04). CONCLUSION: This study provides evidence for the potential health benefits of training posture correction and stretching movements on controlling lumbar lordosis and reducing lumbar pain during pregnancy.

Validity and Reliability of Persian Version of Henry Ford Hospital Headache Disability Inventory Questionnaire.

BACKGROUND: A limited number of headache disability indices exist that can evaluate and manage different disabilities related to headache among Iranian patients. OBJECTIVE: This study aimed to translate and validate the Persian version of the Henry Ford headache disability inventory (HDI). METHODS: The original questionnaire was translated and culturally adapted to the Persian setting. A total of 250 patients with chronic headache were enrolled in this study. The questionnaire's face validity, content validity, and convergent validity with Short-Form Health Survey (SF-36) were evaluated and a confirmatory factor analysis (CFA) was conducted. Its internal consistency was also assessed and its short- and long-term test-retest reliability were examined by intraclass correlation coefficient (ICC). RESULTS: The content validity indices were 0.85, 0.99, and 0.97 for simplicity, relevance, and clarity, respectively. The content validity ratio was calculated as one for all items. The findings of CFA confirmed that this index had a good fit. Cronbach's alpha was 0.91, 0.82, and 0.86 for the entire questionnaire as well as its functional and emotional subscales, respectively. The ICC was also calculated as 0.97 for the total inventory. The convergent validity showed significant negative correlations between HDI and short-form health survey items. CONCLUSION: The validity and reliability of the Persian version of the HDI were confirmed. This questionnaire can explore the disabilities of Persian-speaking people with headache disorders.

A mechatronics data collection, image processing, and deep learning platform for clinical posture analysis: a technical note.

Static and dynamic posture analysis was a critical clinical examination in physiotherapy and rehabilitation. It was a time-consuming task for clinicians, so a semi-automatic method can facilitate this process as well as provide well-documented medical records and strong infrastructure for deep learning scenarios. The current research presents a mechatronics platform for static and real-time dynamic posture analysis, which consisted of hybrid computational modules. Our study was a developmental and applied research according to a system development life cycle. The designed modules are as follows: (1) a mechanical structure includes patient place, 360-degree engine, mirror, laser, distance meter, and cams; (2) a software module includes data collection, electronic medical record, semi-automatic image analysis, annotation, and reporting, and (3) a network to exchange raw data with deep learning server. Patients were informed about the research by their healthcare provider and all data were transformed into a Fourier format, in which the patients remained autonomous without a bit of information. The results show acceptable reliability and validity of the instruments. Also, a telerehabilitation application was designed to cover the patients after diagnosis. We suggest a longer time for data acquisition. It will lead to a more accurate and fully automated dynamic posture analysis. The result of this study suggest that the designed mechatronics device used in conjunction with smartphone application is a valid tool that can be used to obtain reliable measurements.

Comparison of lumbar segmental stabilization and general exercises on clinical and radiologic criteria in grade-I spondylolisthesis patients: A double-blind randomized controlled trial.

OBJECTIVES: The effects of different physiotherapy protocols on patients suffering from grade-I spondylolisthesis have been thus far examined in a limited number of clinical trials. Therefore, the main purpose of this study was to compare the effects of lumbar segmental stabilization and general exercises on clinical and radiologic criteria in grade-I spondylolisthesis patients. METHODS: This study was a double-blind randomized controlled trial (RCT) with a test-retest design and parallel groups. A total of 26 patients with grade-I spondylolisthesis were thus randomly assigned to experimental group (13 patients, lumbar segmental stabilization exercises) and control group (13 patients, general exercises). Subsequently, pain, functional disability, kinesiophobia, translational motion, angular motion and slip percentage of the vertebra were investigated. RESULTS: Of the 120 people recruited in this study, only 26 patients were eligible. According to pre/post-intervention comparison, a statistically significant decrease was observed in the experimental group in terms of pain (p = 0.000), functional disability (p = 0.004), kinesiophobia (p = 0.002), translational motion (p = 0.043) and angular motion (p = 0.011), but not for slip percentage (p = 0.122). Considering the control group, a statistically significant decline was reported for pain (p = 0.043) and functional disability (p = 0.002). However, no significant differences were found for other variables in the control group. With regard to inter-group comparison, there was no statistically significant difference between the two groups regarding the given variables except for kinesiophobia (p = 0.040). CONCLUSION: Both lumbar segmental stabilization and general exercises led to reduction in pain and functional disability of patients with grade-I spondylolisthesis. Therefore, lumbar segmental stabilization exercises seemed to be better than general ones with reference to improving kinesiophobia and intervertebral movements.

The effects of shock wave and dry needling on active trigger points of upper trapezius muscle in patients with non-specific neck pain: A randomized clinical trial.

BACKGROUND: Chronic neck pain is associated with various myofascial trigger points (MTrPs). OBJECTIVE: A single-blind randomized clinical trial was designed to compare the effects of extracorporeal shock wave therapy (ESWT) with dry needling (DN) techniques on the upper trapezius muscle trigger point in patients with non-specific neck pain (NSNP). METHODS: Seventy patients with NSNP and active MTrPs of the upper trapezius muscle were randomly divided into two groups: an ESWT group (n= 35) and a DN group (n= 35). Treatment sessions were performed for three weeks and all participants received related intervention once a week. The outcome measures were pain intensity, measured by a numeric pain rating scale (NPRS), pain pressure threshold (PPT), measured with a digital algometer, and functional disability, evaluated by using the neck disability index (NDI). RESULTS: NPRS and NDI were significantly decreased in the DN group and ESWT group (P< 0.05). Also, the PPT was significantly increased in the DN group and ESWT. However, there was no significant difference in pain intensity, NDI, and the PPT between the two groups (P⩾ 0.05). CONCLUSION: Both ESWT and DN can be employed to treat MTrPs of the upper trapezius muscle in patients with NSNP.

Newfangled Procedures Using X-ray to Determine the Cobb Angle in Patients with Scoliosis: An Updated Systematic Review.

BACKGROUND: Scoliosis is a three-dimensional deformity of the spine. It is usually assessed by measuring Cobb angle. Nowadays, due to increasing effectiveness of image processing and machine vision, willingness to apply these methods has improved considerably in determining scoliosis of Cobb angle. METHODS: In accordance with the PRISMA guideline, a broad electronic search of all English language literature was conducted on the topic through four databases, including MEDLINE, Web of Science, Scopus, and the Cochrane Library from 2012 (last search date from earlier review) to 30 March 2017. RESULTS: Twelve studies were included. 90% labeled high-quality were selected for analysis. Eighty percent of the selected studies were published in the period between 2012 and 2017. Three new procedures were used to measure the Cobb angle. One study used automated procedure (7%), two studies used smartphone procedure (14%), and nine studies used the semiautomatic procedure of Cobb measurement (79%). Seven studies reported reproducibility and repeatability. Reproducibility range was 0.72 to 1 in reporting of ICC. Repeatability has a high range in three separated methods. CONCLUSION: Computerized assessment method (Automatic and Semi-automatic) is most commonly performed in Cobb measurement. Semi-automatic is an effective measurement option for computerized assessment Cobb angle. There is no significant difference between manual, computer- based, and smartphone-based methods in described measures.

Effects of McGill stabilization exercises and conventional physiotherapy on pain, functional disability and active back range of motion in patients with chronic non-specific low back pain.

[Purpose] The aim of this study was to compare the effects of "McGill stabilization exercises" and "conventional physiotherapy" on pain, functional disability and active back flexion and extension range of motion in patients with chronic non-specific low back pain. [Subjects and Methods] Thirty four patients with chronic non-specific low back pain were randomly assigned to McGill stabilization exercises group (n=17) and conventional physiotherapy group (n=17). In both groups, patients performed the corresponding exercises for six weeks. The visual analog scale (VAS), Quebec Low Back Pain Disability Scale Questionnaire and inclinometer were used to measure pain, functional disability, and active back flexion and extension range of motion, respectively. [Results] Statistically significant improvements were observed in pain, functional disability, and active back extension range of motion in McGill stabilization exercises group. However, active back flexion range of motion was the only clinical symptom that statistically increased in patients who performed conventional physiotherapy. There was no significant difference between the clinical characteristics while compared these two groups of patients. [Conclusion] The results of this study indicated that McGill stabilization exercises and conventional physiotherapy provided approximately similar improvement in pain, functional disability, and active back range of motion in patients with chronic non-specific low back pain. However, it appears that McGill stabilization exercises provide an additional benefit to patients with chronic non-specific low back, especially in pain and functional disability improvement.

Hip joint torques in type II diabetes with and without neuropathy.

BACKGROUND: Patients with diabetes and peripheral neuropathy demonstrate significantly reduced peak torques at the peripheral joints. OBJECTIVES: The aim of this study was to assess isometric and concentric peak torques of the hip joint in people with type II diabetes with and without peripheral neuropathy in comparison with healthy participants. METHODS: 27 patients with type II diabetes including 15 patients without peripheral neuropathy, 12 patients with diabetes and peripheral neuropathy and 15 healthy people participated. Isometric and concentric peak torques of hip flexion, extension, adduction and abduction of the non-dominant leg were measured by motorized dynamometer. RESULTS: Peak and average peak concentric torques of the hip extension and abduction in patients with diabetes and peripheral neuropathy were lower than those patients with diabetes and control group. Angle of extension peak torque was significantly greater in patients with diabetes and peripheral neuropathy compared with other groups. Angle of flexion peak torque was lower in the patients with diabetes and peripheral neuropathy. CONCLUSIONS: Torque related parameters in patients with type II diabetes with or without peripheral neuropathy, are different from healthy subjects. As a result, patients with diabetes especially with peripheral neuropathy are more susceptible of injury and disability in lower limbs.

Assessment of forward head posture in females: observational and photogrammetry methods.

BACKGROUND: There are different methods to assess forward head posture (FHP) but the accuracy and discrimination ability of these methods are not clear. OBJECTIVES: Here, we want to compare three postural angles for FHP assessment and also study the discrimination accuracy of three photogrammetric methods to differentiate groups categorized based on observational method. METHOD: All Seventy-eight healthy female participants (23 ± 2.63 years), were classified into three groups: moderate-severe FHP, slight FHP and non FHP based on observational postural assessment rules. Applying three photogrammetric methods - craniovertebral angle, head title angle and head position angle - to measure FHP objectively. RESULTS: One - way ANOVA test showed a significant difference in three categorized group's craniovertebral angle (P< 0.05, F=83.07). There was no dramatic difference in head tilt angle and head position angle methods in three groups. According to Linear Discriminate Analysis (LDA) results, the canonical discriminant function (Wilks'Lambda) was 0.311 for craniovertebral angle with 79.5% of cross-validated grouped cases correctly classified. CONCLUSION: Our results showed that, craniovertebral angle method may discriminate the females with moderate-severe and non FHP more accurate than head position angle and head tilt angle. The photogrammetric method had excellent inter and intra rater reliability to assess the head and cervical posture.

Clinical care improvement with use of health information technology focusing on evidence based medicine.

OBJECTIVES: Healthcare institutions need timely patient information from various sources at the point-of-care. Evidence-based medicine (EBM) is a tool for proper and efficient incorporation of the results of research in decision-making. Characteristics of medical treatment processes and practical experience concerning the effect of EBM in the clinical process are surveyed. METHODS: A cross sectional survey conducted in Tehran hospitals in February-March 2012 among 51 clinical residents. The respondents were asked to apply EBM in clinical decision-making to answer questions about the effect of EBM in the clinical process. A valid and reliable questionnaire was used in this study. RESULTS: EBM provides a framework for problem solving and improvement of processes. Most residents (76%) agreed that EBM could improve clinical decision making. Eighty one percent of the respondents believed that EBM resulted in quick updating of knowledge. They believed that EBM was more useful for diagnosis than for treatment. There was a significant association between out-patients and in-patients in using electronic EBM resources. CONCLUSIONS: Research findings were useful in clinical practice and decision making. The computerized guidelines are important tools for improving clinical process quality. When learning how to use IT, methods of search and evaluation of evidence for diagnosis, treatment and medical education are necessary. Purposeful use of IT in clinical processes reduces workload and improves decision-making.
