    STUDY DESIGN: A prospective study.

    OBJECTIVE: The aim of this study was to analyze the proximal thoracic (PT) flexibility and its compensatory ability above the "potential UIV."

    SUMMARY OF BACKGROUND DATA: Shoulder and neck imbalance can be caused by overcorrection of the main thoracic (MT) curve due to inability of PT segment to compensate.

    METHODS: Cervical supine side bending (CSB) radiographs of 100 Lenke 1 and 2 patients were studied. We further stratified Lenke 1 curves into Lenke 1-ve: PT side bending (PTSB) 80.0% of cases of the PT segment were unable to compensate at T3-T6. In Lenke 1+ve curves, 78.4% were unable to compensate at T6, followed by T5 (75.7%), T4 (73.0%), T3 (59.5%), T2 (27.0%), and T1 (21.6%). In Lenke 1-ve curves, 36.4% of cases were unable to compensate at T6, followed by T5 (45.5%), T4 (45.5%), T3 (30.3%), T2 (21.2%), and T1 (15.2%). A significant difference between Lenke 1-ve and Lenke 1+ve was observed from T3 to T6. The difference between Lenke 1+ve and Lenke 2 curves was significant only at T2.

    CONCLUSION: The compensation ability and the flexibility of the PT segments of Lenke 1-ve and Lenke 1+ve curves were different. Lenke 1+ve curves demonstrated similar characteristics to Lenke 2 curves.

    OBJECTIVE: The systematic review and meta-analysis aims to determine the efficacy and safety of droxidopa in the treatment of orthostatic hypotension, following its recent approvals in the United States.

    METHODS: MEDLINE, EMBASE, PubMed, Cochrane Controlled Trials Register, Web of Science, ProQuest, and the WHO Clinical Trials Registry were searched. Studies were included if they randomized adults with orthostatic hypotension to droxidopa or to control, and outcomes related to symptoms, daily activity, blood pressure, or adverse events. Data were extracted independently by two reviewers. Risk of bias was judged against the Cochrane risk of bias tool and quality of evidence measured using Grading of Recommendations Assessment, Development and Evaluation criteria. A fixed-effects model was used for pooled analysis.

    RESULTS: Of 224 identified records, four studies met eligibility, with a pooled sample size of 494. Study duration was between 1 and 8 weeks. Droxidopa was effective at reducing dizziness [mean difference -0.97 (95% confidence interval -1.51, -0.42)], overall symptoms [-0.52 (-0.98, -0.06)] and difficulty with activity [-0.86 (-1.34, -0.38)]. Droxidopa was also effective at improving standing SBP [3.9 (0.1, 7.69)]. Rates of adverse events were similar between droxidopa and control groups, including supine hypertension [odds ratio 1.93 (0.87, 4.25)].

    CONCLUSION: Droxidopa is well tolerated and effective at reducing the symptoms associated with neurogenic orthostatic hypotension without increasing the risk of supine hypertension.

    Conclusion: The obtained results conclude piano players are highly prone to the risk of developing PRMSD in the upper body.

    Results: The findings showed piano players have a higher NDI, lower CVA, and RSP when compared with the non-piano players at a statistically significant level of p-value <0.05.

    Objective: Playing-related musculoskeletal disorders (PRMSD) are a common problem for the pianist. The poor upper body ergonomics influences the natural positioning of the neck and shoulders, which involves forward head posture (FHP) and rounded shoulder posture (RSP). This misaligned position could produce a sensation of pain over the upper body, which affects the piano player and computer users with similar ergonomic posture. Recently, photogrammetry methods are commonly applied in a clinical setting to assess posture. The goal of this research is to compare the upper body playing-related muscu-loskeletal disorders between the piano and the non-piano players by applying photogrammetry.

    Materials and Methods: This causal-comparative study includes 70 participants with 35 piano and 35 non-piano players. The participant's FHP was assessed using a digitized photo to record the Craniovertebral angle (CVA) with the support of Kinovea software. Besides, digital Vernier Calliper used to assess the scapular index on the RSP and Neck disability indices (NDI) used to measure neck pain and functional disability of the participants.

    BACKGROUND AND AIM: Variations in the Chicago 3.0 normative metrics may exist with different postures and with different provocative swallow materials in a healthy Asian population.

    METHOD: Eligible healthy Malay volunteers were invited to undergo the high-resolution esophageal manometry (inSIGHT Ultima, Diversatek Healthcare, Milwaukee, WI, USA). In recumbent and standing positions, test swallows were performed using liquid, viscous, and solid materials. Metrics including integrated relaxation pressure 4 s (IRP-4 s, mmHg), distal contractile integral (DCI, mmHg s cm), distal latency (DL, s), and peristaltic break (PB, cm) were reported in median and 95th percentile.

    RESULTS: Fifty of 57 screened participants were recruited, and 586 saline, 265 viscous, and 261 solid swallows were analyzed. Per-patient wise, in the recumbent position, 95th percentile for IRP-4 s, DCI, DL, and PB were 16.5 mmHg, 2431 mmHg s cm, 8.5 s, and 7.2 cm, respectively. We observed that with each posture, the use of viscous swallows led to changes in DL, but the use of solid swallows led to more changes in the metrics including DCI and length of PB. Compared with a recumbent posture, anupright posture led to lower IRP-4 s and DCI values. Both per-patient analysis and per-swallow analyses yielded almost similar results when comparing the different postures and types of swallows. No major motility disorders were observed in this cohort of asymptomatic population. However, more motility disorders were reported in the upright position.

    CONCLUSIONS: Variations in metrics can be observed in different postures and with different provocative swallow materials in a healthy population. The normative Chicago 3.0 metrics are also determined for the Malay population.

    STUDY OBJECTIVES: Patients suspected to have sleep-disordered breathing underwent an overnight polysomnography using a divided nasal cannula to gain additional information about the nasal cycle during sleep.

    METHODS: This was a prospective, observational cohort study replacing the undivided nasal cannula with a divided nasal cannula during routine polysomnography (n = 28).

    RESULTS: Integration of the divided nasal cannula pressure transducer system into routine polysomnography was easy and affordable. Most patients (89%) demonstrated nasal cycle changes during the test. Nasal cycle changes tended to occur during body position changes (62%) and transitions from non-rapid eye movement sleep to rapid eye movement sleep (41%). The mean nasal cycle duration was 2.5 ± 2.1 hours. Other sleep study metrics did not reveal statistically significant findings in relation to the nasal cycle.

    CONCLUSIONS: Replacing an undivided nasal cannula with a divided nasal cannula is easy to implement, adding another physiologic measure to polysomnography. Although the divided nasal cannula did not significantly affect traditional polysomnographic metrics such as the apnea-hypopnea index or periodic limb movement index based on this small pilot study, we were able to replicate past nasal cycle findings that may be of interest to sleep clinicians and researchers. Given the ease with which the divided nasal cannula can be integrated, we encourage other sleep researchers to investigate the utility of using a divided nasal cannula during polysomnography.

    BACKGROUND: Evidence on the health risks of sitting is accumulating. However, research identifying factors influencing sitting time in adults is limited, especially in Asian populations. This study aimed to identify socio-demographic and lifestyle correlates of occupational, leisure and total sitting time in a sample of Singapore working adults.

    METHODS: Data were collected between 2004 and 2010 from participants of the Singapore Multi Ethnic Cohort (MEC). Medical exclusion criteria for cohort participation were cancer, heart disease, stroke, renal failure and serious mental illness. Participants who were not working over the past 12 months and without data on sitting time were excluded from the analyses. Multivariable regression analyses were used to examine cross-sectional associations of self-reported age, gender, ethnicity, marital status, education, smoking, caloric intake and moderate-to-vigorous leisure time physical activity (LTPA) with self-reported occupational, leisure and total sitting time. Correlates were also studied separately for Chinese, Malays and Indians.

    RESULTS: The final sample comprised 9384 participants (54.8% male): 50.5% were Chinese, 24.0% Malay, and 25.5% Indian. For the total sample, mean occupational sitting time was 2.71 h/day, mean leisure sitting time was 2.77 h/day and mean total sitting time was 5.48 h/day. Sitting time in all domains was highest among Chinese. Age, gender, education, and caloric intake were associated with higher occupational sitting time, while ethnicity, marital status and smoking were associated with lower occupational sitting time. Marital status, smoking, caloric intake and LTPA were associated with higher leisure sitting time, while age, gender and ethnicity were associated with lower leisure sitting time. Gender, marital status, education, caloric intake and LTPA were associated with higher total sitting time, while ethnicity was associated with lower total sitting time. Stratified analyses revealed different associations within sitting domains for Indians compared to Chinese and Malays.

    CONCLUSION: Our findings highlight the need to focus on separate domains of sitting (occupational, leisure or total) when identifying which factors determine this behavior, and that the content of intervention programs should be tailored to domain-specific sitting rather than to sitting in general. Finally, our study showed ethnic differences and therefore we recommend to culturally target interventions.

    BACKGROUND: Proprioception is the ability to sense the body position, muscle sense, joint stability and posture. As balance decreases during the process of aging, knee proprioception has a critical role in body balance and daily activities. Exergaming has shown to be a potentially effective and more enjoyable form of exercise delivery.

    OBJECTIVE: The purpose of this study was to determine the effect of an 8-week Xbox Kinect exercise program on knee proprioception in healthy older adults.

    METHODOLOGY: Thirty-two elderly men who were 65 years of age or older were randomly allocated to either a control or experimental group (allocation ratio 1:1). The experimental group received an exergame intervention that included Xbox Kinect with games focusing on movements of the knee joint for 8 weeks (three times per week and 40min per sessions). A Biodex Isokinetic Dynamometer was used to measure knee joint position sense before and after the exercise program.

    RESULTS: After eight weeks of training, knee proprioception significantly improved in the intervention group for several knee joint angles: 30° (3.5±1.1), 45° (3.1±0.9), and 60° (3.0±0.6) compared to the control group 30° (5.2±0.8), 45° (5.2±0.8), and 60° (6.2±0.9) (dominant leg F1, 28=23.469, p=0.001. ƞ2=0.456; non-dominant leg F1, 28=23.076, p=0.001. ƞ2=0.452).

    CONCLUSION: The results from this study indicate that exergame intervention can enhance knee proprioception in elderly men.

    Prolonged standing can cause discomfort on the body of the workers and can lead to injury and occupational disease. One of the ergonomic intervention is through improving the work-rest scheduling. The purpose of this study are to identify the fatigue level from the perception of the worker and to investigate the impact of the work-rest scheduling to the standing workers for 12 h working time with a different gender. This study involved two methods which are self-assessment of the worker and direct measurement by using electromyography (EMG). For self-assessment, 80 workers have been interviewed using questionnaire in order to identify the fatigue level. For direct measurement, EMG was attached to the 15 selected workers at their respective leg and lower back to analyse the muscle efforts. In terms of perception, the results show the discomfort and fatigue level at the lower body region in the following order as foot ankle, lower back and leg. There is a significant difference between gender on discomfort pain for foot ankle and leg. The results show short frequent break by 10 min can reduce the fatigue at the leg and infrequent long break is preferable in order to reduce the fatigue at the lower back. In conclusion, it was found that prolonged standing affect the muscle fatigue and discomfort especially lower extremities such as foot ankle, lower back and leg. Besides that, different type of work rest scheduling and gender have significant result towards the muscle fatigue development.

    Many species from several different families of fishes perform mouthbrooding, where one of the sexes protects and ventilates the eggs inside the mouth cavity. This ventilation behaviour differs from gill ventilation outside the brooding period, as the normal, small-amplitude suction-pump respiration cycles are alternated with actions including near-simultaneous closed-mouth protrusions and high-amplitude depressions of the hyoid. The latter is called churning, referring to its hypothetical function in moving around and repositioning the eggs by a presumed hydrodynamic effect of the marked shifts in volume along the mouth cavity. We tested the hypothesis that churning causes the eggs located posteriorly in the mouth cavity to move anteriorly away from the gill entrance. This would prevent or clear accumulations of brood at the branchial basket, which would otherwise hinder breathing by the parent. Dual-view videos of female Nile tilapias (Oreochromis niloticus) during mouthbrooding showed that churning involves a posterior-to-anterior wave of expansion and compression of the head volume. Flow visualisation with polyethylene microspheres revealed a significant inflow of water entering the gill slits at the zone above the pectoral fin base, followed by a predominantly ventral outflow passing the ventrolaterally flapping branchiostegal membranes. X-ray videos indicated that particularly the brood located close to the gills is moved anteriorly during churning. These data suggest that, in addition to mixing of the brood to aid its oxygenation, an important function of the anterior flow through the gills and buccal cavity during churning is to prevent clogging of the eggs near the gills.

    Traffic police riders are exposed to prolonged static postures causing significant angular deviation of the musculoskeletal, including the lumbar angle (L1-L5). This postural alteration contributes to awkward posture, musculoskeletal disorders and spinal injury, especially in the lower back area, as it is one of the most severe modern diseases nowadays. Thus, the study aimed to evaluate the effect of lumbar support with a built-in massager system on spinal angle profiles among traffic police riders. A randomised controlled trial (pre-testpost-test control design) was used to assess spinal angle pattern while riding the high-powered motorcycle for 20 minutes. Twenty-four traffic police riders were randomly selected to participate and 12 riders were assigned to the control group and 12 riders to the experimental group. The pre-test and post-test were conducted at a one-week interval. Each participant was required to wear a TruPosture Smart Shirt (to monitor spinal posture). The TruPosture Apps recorded the spinal angle pattern. The data indicated that the police riders using motorcycle seat with lumbar support and built-in massager system showed a huge improvement in maintaining posture which only involves slight spinal angle deviation changes from the spinal reference angle throughout the 20 minutes ride. The data collected then were analysed using the Mann-Whitney test and Wilcoxon signed-ranked test to verify a statistically significant difference between and within the control and experimental groups. There were significant differences in all sensors between the control group and experimental groups (p<0.05) and within the experimental group. According to the findings, it can be said that the ergonomic intervention prototype (lumbar support with built-in massager system) successfully helps to maintain and improve the natural curve of the spinal posture. This indirectly would reduce the risk of developing musculoskeletal disorders and spinal injury among traffic police riders.

    Human motion is a daily and rhythmic activity. The exoskeleton concept is a very positive scientific approach for human rehabilitation in case of lower limb impairment. Although the exoskeleton shows potential, it is not yet applied extensively in clinical rehabilitation. In this research, a fuzzy based control algorithm is proposed for lower limb exoskeletons during sit-to-stand and stand-to-sit movements. Surface electromyograms (EMGs) are acquired from the vastus lateralis muscle using a wearable EMG sensor. The resultant acceleration angle along the z-axis is determined from a kinematics sensor. Twenty volunteers were chosen to perform the experiments. The whole experiment was accomplished in two phases. In the first phase, acceleration angles and EMG data were acquired from the volunteers during both sit-to-stand and stand-to-sit motions. During sit-to-stand movements, the average acceleration angle at activation was 11°-48° and the EMG varied from -0.19 mV to +0.19 mV. On the other hand, during stand-to-sit movements, the average acceleration angle was found to be 57.5°-108° at the activation point and the EMG varied from -0.32 mV to +0.32 mV. In the second phase, a fuzzy controller was designed from the experimental data. The controller was tested and validated with both offline and real time data using LabVIEW.

    INTRODUCTION: Cognitive stress (CS) changes the peripheral attributes of a muscle, but its effect on multi-head muscles has not been investigated. The objective of the current research was to investigate the impact of CS on the three heads of the triceps brachii (TB) muscle.

    METHODS: Twenty-five young and healthy university students performed a triceps push-down exercise at 45% one repetition maximum (1RM) with and without CS until task failure, and the rate of fatigue (ROF), endurance time (ET) and number of repetitions (NR) for both exercises were analyzed. In addition, the first and last six repetitions of each exercise were considered non-fatiguing (NF) and fatiguing (Fa), respectively, and the root mean square (RMS), mean power frequency (MPF) and median frequency (MDF) for each exercise repetition were evaluated.

    RESULTS: The lateral and long head showed significant differences (P<0.05) in the ROF between the two exercises, and all the heads showed significant (P<0.05) differences in the RMS between the two exercises under NF conditions. Only the long head showed a significant difference (P<0.05) in the MPF and MDF between the two exercises. CS increases the ET (24.74%) and NR (27%) of the exercise. The three heads showed significant differences (P<0.05) in the RMS, MPF and MDF under all exercise conditions.

    CONCLUSION: A lower ROF was obtained with CS. In addition, the RMS was found to be better approximator of CS, whereas MPF and MDF were more resistant to the effect of CS. The results showed that the three heads worked independently under all conditions, and the non-synergist and synergist head pairs showed similar behavior under Fa conditions. The findings from this study provide additional insights regarding the functioning of each TB head.

    PURPOSE: Goal-directed movements tend to resemble the characteristics of previously executed actions. Here we investigated whether a single bout of strength training, which typically involves stereotyped actions requiring strong neural drive, can bias subsequent aiming behavior toward the direction of trained forces.

    METHODS: In experiment 1 (n = 10), we tested the direction of force exerted in an isometric aiming task before and after 40 repetitions of 2-s maximal-force ballistic contractions toward a single directional target. In experiment 2 (n = 12), each participant completed three training conditions in a counterbalanced crossover design. In two conditions, both the aiming task and the training were conducted in the same (neutral) forearm posture. In one of these conditions, the training involved weak forces to determine whether the level of neural drive during training influences the degree of bias. In the third condition, high-force training contractions were performed in a 90° pronated forearm posture, whereas the low-force aiming task was performed in a neutral forearm posture. This dissociated the extrinsic training direction from the pulling direction of the trained muscles during the aiming task.

    RESULTS: In experiment 1, we found that aiming direction was biased toward the training direction across a large area of the work space (approximately ±135°; tested for 16 targets spaced 22.5° apart), whereas in experiment 2, we found systematic bias in aiming toward the training direction defined in extrinsic space, but only immediately after high-force contractions.

    CONCLUSION: Our findings suggest that bias effects of training involving strong neural drive generalize broadly to untrained movement directions and are expressed according to extrinsic rather than muscle-based coordinates.

    The proper diagnosis of parkinsonian disorders usually involves three steps: identifying core features of parkinsonism; excluding other causes; and collating supportive evidence based on clinical signs or investigations. While the recognition of cardinal parkinsonian features is usually straightforward, the appreciation of clinical features suggestive of specific parkinsonian disorders can be challenging, and often requires greater experience and skills. In this review, we outline the clinical features that are relevant to the differential diagnosis of common neurodegenerative parkinsonian disorders, including Parkinson's disease, multiple system atrophy, progressive supranuclear palsy, and corticobasal degeneration. We aim to make this process relatable to clinicians-in-practice, therefore, have categorised the list of clinical features into groups according to the typical sequence on how clinicians would elicit them during the examination, starting with observation of facial expression and clinical signs of the face, spotting eye movement abnormalities, examination of tremors and jerky limb movements, and finally, examination of posture and gait dysfunction. This review is not intended to be comprehensive. Rather, we have focused on the most common clinical signs that are potentially key to making the correct diagnosis and those that do not require special skills or training for interpretation. Evidence is also provided, where available, such as diagnostic criteria, consensus statements, clinicopathological studies or large multi-centre registries. Pitfalls are also discussed when relevant to the diagnosis. While no clinical signs are pathognomonic for certain parkinsonian disorders, certain clinical clues may assist in narrowing a differential diagnosis and tailoring focused investigations for the individual patient.

    The prevalence of Musculoskeletal Symptoms (MSS) rapidly increases and it is recognized as a significant health outcome in agricultural sector. Agricultural ergonomics risk factor is one of hazards constantly arising from all job task activities including awkward postures and heavy lifting. Job hazard analyses (JHA) were conducted to assess the exposure of ergonomics risk factors in Malaysia Pineapple Plantation. The analyses performed involved two steps. They were: 1) guidelines and manual book Malaysia Pineapple Plantation as references; and 2) conducting walkthrough observation based on checklist approaches at the plantation. The identified risk factors were prolonged exposure of standing, squatting, stooping and kneeling, highly repetitive motion on the lower limbs, deviation and twisting of wrist and lastly, heavy lifting. The analyses confirmed that the exposure to ergonomics risk factors in pineapple plantation is high. It would be desirable to reduce the risk factors by educating and training the pineapple workers to perform their task with strong consideration of occupational safety and health.

    Introduction: Low back pain (LBP) is a common symptom among working population worldwide. Foggers prone to have LBP because there are exposed to physical factors such as lifting heavy object, awkward body posture and vibration. However, LBP had never been studied among the fogger. The objective of this study was to determine the prevalence and the factors associated with LBP. Methods: A cross-sectional study was carried out in all District Health Office in Johor, Malaysia by using a validated self-administered questionnaire and anthropometric measure-ments. Chi-square or Fisher’s exact test was used for inferential statistic and multiple logistic regression was used to determine the associated factors. The significance level was determined at p < 0.05. Results: The response rate was 83.9%. Majority of them are male (99.6%), Malay (95.8%), married (85.8%) and educated up to secondary school (53.5%). Majority of respondents do not have part time job (89.6%) but they work overtime everyday (62.7%). Most of them do four hours overtime daily (77.3%). The prevalence of LBP was 68.5% among respondents. There was a significant association between doing part time job, duration of doing overtime per week, body mass index (BMI) and duration of fogging activities. Finally, the associated factors of LBP were doing overtime for more than 20 hours per week (adjusted OR=1.914, 95% CI [1.102, 3.324], p = 0.021), BMI of more than 23.00 kg/m2 (adjusted OR=2.066, 95% CI [1.090, 3.916], p = 0.026) and having no part time job (adjusted OR=0.135, 95% CI [0.031, 0.599], p = 0.021). Conclusion: Prevention needs to be initiated to change the modifiable factors of LBP in order to reduce the prevalence of LBP among them.

    INTRODUCTION: The aim of this study was to determine the concurrent validity and reliability of telerehabilitation (TR)-based evaluation of the cervical spine among adults with non-specific neck pain (NS-NP).

    METHODS: A total of 11 participants with NS-NP were recruited. Pain intensity, active range of motion (AROM), posture, deep neck flexor (DNF) endurance, combined neck movements and disability were measured using face-to-face and TR methods, with a one-hour break in between. TelePTsys, an image-based TR system, was used for TR assessment.

    RESULTS: A high degree of concurrent validity for pain (bias = 0.90), posture (bias = 0.96°), endurance (bias = -2.3 seconds), disability (bias = 0.10), AROM (extension bias = -0.60 cm, flexion bias = 1.2 cm, side flexion bias = -1.00, rotation bias = -0.30 cm) was found. Standard error of measurement and coefficient of variation (CV) values were within the acceptable level for concurrent validity, except the CV for cervical flexion and endurance. There was a high degree of reliability demonstrated for pain, posture, AROM, endurance and disability measurements. The average-measure interclass correlation coefficient (ICC(3,1)) ranged from 0.96 to 0.99 for inter-rater, and 0.93 to 0.99 for intra-rater reliabilities. There was moderate agreement for combination movement for validity (78.5%, p

    Objective. Limited models are available to predict work-relatedness of musculoskeletal disorders (MSDs) among semiconductor back-end workers. This study aims to develop a model to predict the MSDs development among back-end workers. Method. Potential MSD risk factors were extracted from 277 work compensation investigation reports conducted between 2011-2019. Binary logistic regression approach was used to determine significant predictors. Results. Significant predictors (p

    Introduction Children with cerebral palsy (CP) are often prescribed Rehabilitation and Seating Systems (RSS) to assist in daily activities, posture improvement and prevention of muscular-skeletal complications. In Sarawak, a special project to produce RSS was started under a partnership of a Japanese physiotherapist, health department and the community using local material.Aim To document the RSS project and to determine usefulness and costaffordability of these systems for cerebral palsy children and their families.
    Methods The details of RSS manufactured were retrieved from the clinic notes and secretary file. Parents of children who received the seating systems between July 2004 and September 2008 were invited to complete a 5-point Global Parental Perception Questionnaire (GPPQ) between December 2008 and January 2009.
    Results 277 RSS were manufactured between July 2004 and February 2011 (which included modified wheel chair, wooden chair, corner chair, buggy chair and standing frame), and used by children all over Sarawak. Parents of 73 children who used the seating systems completed the 5-points GPPQ. Ten families required full sponsorship. Children spent more time sitting up and brought outdoor more often after the systems became available. Majority of parents reported positive experience in their children with sitting ability, smiles, interaction with people, learning skills and easiness of doing physiotherapy. No change was noted with passing of motion drooling / oral secretion. Most parents agreed that the cost was affordable and worth paying.
    Conclusions A community based initiative to manufacture RSS by using locally available material and skill, at affordable price for the parents was feasible and useful for the family/children with CP.
