Mokhtar S, Azizi ZA, Govindarajanthran N

Asian J Surg, 2008 Jul;31(3):124-9.
PMID: 18658010

OBJECTIVE: This study investigated the effects of posture and also intermittent foot and calf compression on peak systolic flow of the popliteal artery in a normal population.
METHODS: This was a prospective study carried out in normal subjects at the Vascular Laboratory, Department of Surgery, Hospital Kuala Lumpur, from March 2006 to September 2006. The study compared the popliteal artery blood flow during change of posture from the horizontal (supine) to the sitting position and the effect of intermittent pneumatic compression (IPC) of the foot and calf on popliteal artery blood flow immediately and 10 minutes after cessation of compression.
RESULTS: A total of 15 subjects involving 30 limbs were examined in this study. On comparing flows between the horizontal and sitting position, there was a mean reduction in blood flow of 23% (p < 0.005). Immediately after compression of the foot and calf, there was an increase in blood flow of between 4% and 35% with a mean of 15% (p < 0.05). Peak systolic flows at 10 minutes postcompression were 536 +/- 95 mL/min, which was still significantly higher than precompression measurements.
CONCLUSION: There is a significant reduction in popliteal artery blood flow on changing from the supine to the sitting position. Popliteal artery blood flow is higher than baseline after 15 minutes of intermittent pneumatic foot and calf compression. The increase in popliteal artery blood flow is still present 10 minutes after cessation of IPC.

Lope RJ, Kong WK, Lee VW, Tiew WT, Wong SY

Med J Malaysia, 2010 Mar;65(1):45-8.
PMID: 21265248 MyJurnal

Several modifiable risk factors for sudden infant death syndrome (SIDS) have been identified such as sleeping prone or on the side, sleeping on a soft surface, bed-sharing, no prenatal care and maternal ante-natal smoking. A cross-sectional survey of infant sleep and care practices was conducted among parents of babies aged below 8 months to determine the prevalence and predictors of non-supine sleep position and the prevalence of other high-risk infant care practices for SIDS. Of 263 infants, 24.7% were placed to sleep in the non-supine position and age of infants was a factor positively associated with this (adjusted odds ratio 1.275, 95% CI=1.085, 1.499). The most common modifiable risk factor was the presence of soft toys or bedding in the infants' bed or cot (89.4%). Results from this study indicate that although the predominant sleep position of Malaysian infants in this population is supine, the majority of infants were exposed to other care practices which have been shown to be associated with SIDS.

Study design: A cross-sectional study among health care providers working at one hospital. Objective: To investigate the prevalence, the consequences and the risk factors associated with low back pain (LBP) among hospital staff. Materials and Methods: The study sample consisted of 931 health care providers who answered a pre-established questionnaire including 30 items in two languages. Results: The cumulative life-prevalence of LBP was 72.5% and the yearly prevalence was 56.9%. Chronic LBP prevalence was noted 5.1% of the cases. Treatment was sought in 34.1% of LBP sufferers and 7.3% required sick leave or absence from work due to LBP. Risk factors associated with LBP were professional categories, bad body posture, lifting objects or patients and the increased levels of lifting, levels of job satisfaction and stressful job demands. Conclusion: There was a high prevalence of LBP among hospital staff, resulting in significant medical and socio-professional consequences. Many risk factors were identified that would necessitate multidisciplinary involvement to reduce the LBP incidence and related costs.

Gopalai AA, Senanayake SM, Gouwanda D

IEEE Trans Inf Technol Biomed, 2011 Jul;15(4):608-14.
PMID: 21478080 DOI: 10.1109/TITB.2011.2140378

A force-sensing platform (FSP), sensitive to changes of the postural control system was designed. The platform measured effects of postural perturbations in static and dynamic conditions. This paper describes the implementation of an FSP using force-sensing resistors as sensing elements. Real-time qualitative assessment utilized a rainbow color scale to identify areas with high force concentration. Postprocessing of the logged data provided end-users with quantitative measures of postural control. The objective of this research was to establish the feasibility of using an FSP to test and gauge human postural control. Tests were conducted in eye open and eye close states. Readings obtained were tested for repeatability using a one-way analysis of variance test. The platform gauged postural sway by measuring the area of distribution for the weighted center of applied pressure at the foot. A fuzzy clustering algorithm was applied to identify regions of the foot with repetitive pressure concentration. Potential application of the platform in a clinical setting includes monitoring rehabilitation progress of stability dysfunction. The platform functions as a qualitative tool for initial, on-the-spot assessment, and quantitative measure for postacquisition assessment on balance abilities.

J Bodyw Mov Ther, 2011 Oct;15(4):453-64.
PMID: 21943619 DOI: 10.1016/j.jbmt.2010.10.005

A method for assessing balance, which was sensitive to changes in the postural control system is presented. This paper describes the implementation of a force-sensing platform, with force sensing resistors as the sensing element. The platform is capable of measuring destabilized postural perturbations in dynamic and static postural conditions. Besides providing real-time qualitative assessment, the platform quantifies the postural control of the subjects. This is done by evaluating the weighted center of applied pressure distribution over time. The objective of this research was to establish the feasibility of using the force-sensing platform to test and gauge the postural control of individuals. Tests were conducted in Eye Open and Eye Close states on Flat Ground (static condition) and the balance trainer (dynamic condition). It was observed that the designed platform was able to gauge the sway experienced by the body when subject's states and conditions changed.

MyJurnal

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.

Malaysia has adopted various strategies in developing its space sector. Indigenous space technologies would enable a sustainable growth of the space field and at the same time develop the strategic space technologies. Therefore, issues related to the current space research level are fundamentally crucial to be highlighted. Subsequently, the space focus areas can be derived in order to meet the expectations of the national and international space technology growth requirements, which are moving on to a stronger posture in R&D. In the absence of a strong R&D national space industry leadership, the Malaysian space sector remains in a traditional downstream mode of the world space technology supply chain ever since. The space technology supply chain can be divided into the ground segment and the space segment. This paper examines the current space research activities in Malaysia within the framework of the space technology supply chain. As a result, a preliminary gap in the overview of space research in Malaysia is established.

Biomechanical evaluation of the relationship between postural control and body mass index

Ku PX, Abu Osman NA, Yusof A, Wan Abas WA

J Biomech, 2012 Jun 1;45(9):1638-42.
PMID: 22507349 DOI: 10.1016/j.jbiomech.2012.03.029

Postural stability is crucial in maintaining body balance during quiet standing, locomotion, and any activities that require a high degree of balance performance, such as participating in sports and dancing. Research has shown that there is a relationship between stability and body mass. The aims of this study were to examine the impact that two variables had on static postural control: body mass index (BMI) and gender. Eighty healthy young adults (age=21.7±1.8 yr; height=1.65±0.09 m; mass=67.5±19.0 kg) participated in the study and the static postural control was assessed using the Biodex Balance System, with a 20 Hz sampling rate in the bipedic stance (BLS) and unipedic stance (ULS) for 30s. Five test evaluations were performed for each balance test. Postural control was found to be negatively correlated with increased adiposity, as the obese BMI group performed significantly poorer than the underweight, normal weight and overweight groups during BLS and ULS tests. The underweight, normal weight and overweight groups exhibited greater anterior-posterior stability in postural control during quiet stance. In addition, female displayed a trend of having a greater postural sway than male young adults, although it was evidenced in only some BMI groups. This study revealed that BMI do have an impact on postural control during both BLS and ULS. As such, BMI and gender-specific effects should be taken into consideration when selecting individuals for different types of sporting activities, especially those that require quiet standing.

Fulltext A report on an unusual presentation of autonomic dysreflexia

Suhaida SS, Engkasan JP

Med J Malaysia, 2012 Dec;67(6):616-7.
PMID: 23770957 MyJurnal

A 48-year-old male with complete tetraplegia C6 presented with sweating and flushing of the right half of the face and neck that recurred when lying in supine and left lateral positions. The symptoms subsided immediately upon sitting upright or lying in a right lateral position. The symptoms were associated with occasional mild head discomfort rather than headache and were accompanied by marked elevation of blood pressure, which was 190-200/120-130 mmHg compared to his previous baseline blood pressure of 80-90/50-70 mmHg, and he had a heart rate of 60-70 beats per minute. We believe that post-traumatic syringomyelia, found upon further investigation, was the cause of the Autonomic dysreflexia (AD) in this patient. He was advised to avoid the positions causing the symptoms and the progression of symptoms was monitored regularly. AD might not have been diagnosed in this patient because of the atypical and unusual presentations. Therefore, knowledge and a heightened level of awareness of this possible complication are important when treating individuals with spinal cord injury (SCI).

Development of prolonged standing strain index to quantify risk levels of standing jobs

Halim I, Omar AR

Int J Occup Saf Ergon, 2012;18(1):85-96.
PMID: 22429532

Many occupations in industry such as metal stamping workers, electronics parts assembly operators, automotive industry welders, and lathe operators require working in a standing posture for a long time. Prolonged standing can contribute to discomfort and muscle fatigue particularly in the back and legs. This study developed the prolonged standing strain index (PSSI) to quantify the risk levels caused by standing jobs, and proposed recommendations to minimize the risk levels. Risk factors associated with standing jobs, such as working posture, muscles activity, standing duration, holding time, whole-body vibration, and indoor air quality, were the basis for developing the PSSI. All risk factors were assigned multipliers, and the PSSI was the product of those multipliers. Recommendations for improvement are based on the PSSI; however, extensive studies are required to validate their effectiveness. multipliers, and the PSSI was the product of those multipliers. Recommendations for improvement are based on the PSSI; however, extensive studies are required to validate their effectiveness.

Muthupalaniappen L, Rosdinom R, Suguna M

Clin Ter, 2012;163(1):31-2.
PMID: 22362231

Pisa syndrome or pleurothotonus is the persistent flexion of the body and head to one side giving the appearance of the leaning tower of Pisa. It is most commonly caused by typical and atypical antipsychotic drugs. We report a case of Pisa Syndrome caused by prolonged use of high dose cholinesterase inhibitor, rivastigmine. Symptoms subsided when rivastigmine was withdrawn and did not reappear when a different cholinesterase inhibitor, donepezil was introduced. Physicians should be aware of Pisa syndrome and should alert patient of this possibility when starting and stepping up medications. The purpose of reporting this case is to create awareness among general practitioners as it is a reversible condition which responds to removal of the offending drug.

Ergonomic evaluation of postural stress in school workshop

Hashim AM, Dawal SZ, Yusoff N

Work, 2012;41 Suppl 1:827-31.
PMID: 22316824 DOI: 10.3233/WOR-2012-0249-827

The objective of this study is to compare the evaluation of postural analysis between a self-report questionnaire and physical assessments methods for students aged 13 to 15 years old in school workshop. 336 students were volunteered as participants to fill in the questionnaire and being observed in the workshop. Total of 104 positions were selected and analyzed while students performing their tasks. Questionnaire data was examined to specify the prevalence of postural stress symptoms. The relationship of postural stress by physical assessment methods (RULA and REBA methods) was defined to identify the risk level of students' working posture. From the results, comparison of four factors categorized from total of 22 questions among ages, the mean values were lower for 13 years old students meaning that they were faced higher posture problems while using the workstation. The obtained results from both physical assessment methods and questionnaire analysis have identified 13 years old students faced higher risk exposure. Analysis results emphasized the fact that self-reports questionnaire method has almost accurate as postural evaluation methods to identify physical risks in workplace. The result also shows that an intervention is needed to overcome the posture problems.
