Split Tummy Exercise Program for Reducing Diastasis Recti in Postpartum Primigravidae: A Randomized Controlled Trial.

BACKGROUND: Diastasis rectus abdominis (DRA) involves the separation of the midline abdominal muscles and linea alba and affects more than half of postpartum women. This study aimed to assess the effect of a split tummy exercise program (STEP) on DRA closure in postpartum mothers. METHODS: A randomized controlled trial was conducted from 2008 to 2020 at the Obstetrics and Gynaecology Clinic of the Universiti Kebangsaan Malaysia Medical Centre. Primigravida mothers diagnosed with DRA were selected and randomly assigned to the intervention (n=21) or control (n=20) group. The intervention group underwent a home-based STEP consisting of three phases of nine abdominal exercises. DRA size was assessed at baseline and at 8 weeks postpartum using two-dimensional ultrasound. RESULTS: The mean age of the participants was 28 years (standard deviation, 3.6), with the majority of Malay ethnicity (87.8%) and working mothers (78%). After 8 weeks, the intervention group showed a significant reduction in DRA size of up to 27% (mean difference, 6.17 mm; 95% confidence interval, 3.7-8.7; P<0.001). No significant intergroup DRA changes were observed after 8 weeks of follow-up. CONCLUSION: Early postpartum screening for DRA should be advocated to allow early STEP intervention to ensure favorable outcomes. STEP intervention is an effective postnatal training program for managing DRA.

Musculoskeletal complications of hand-arm vibration syndrome among tyre shop workers in Kelantan, Malaysia.

Objectives. Exposure to hand-arm vibration (HAV) is associated with hand-arm vascular syndrome (HAVS), which is characterized by musculoskeletal complications. However, evidence on this matter has been inconclusive. Therefore, this study aimed to determine and compare the prevalence of musculoskeletal complications of HAVS between a high-exposure (≥5 m·s-2) group and a low-moderate-exposure (<5 m·s-2) group and to explore the factors associated with the musculoskeletal complications of HAVS among tyre shop workers in Kelantan, Malaysia. Methods. A cross-sectional study involving 200 tyre shop workers was carried out. HAV was measured by a vibration meter. The workers were divided into two exposure groups - according to their 8-h time-weighted average, A(8), of vibration exposure - and compared. Results. Almost half of the workers reported musculoskeletal complications of the upper limbs and neck. Only the lifetime vibration dose (LVD) was significantly associated with the development of musculoskeletal complications. Conclusion. The high-exposure group had a higher prevalence of musculoskeletal complications. Only the LVD was significantly associated with complications. However, all factors of the work system, such as ergonomics, handgrip force and posture, might contribute to the development of musculoskeletal complications of HAVS and should be included in assessments.

Lifetime vibration dose correlates with severity of the neurological component of hand-arm vibration syndrome among tyre shop workers in Kelantan, Malaysia.

Introduction. Cumulative lifetime exposure to vibration is believed to contribute to more severe complications of hand-arm vibration syndrome (HAVS). Objectives. To determine prevalence of the neurological component of HAVS and the correlation between lifetime vibration dose (LVD) and neurological severity of HAVS among tyre shop workers in Kelantan. Methods. The cross-sectional study involved 200 tyre shop workers from two districts in Kelantan. Part one data were collected in the field using a questionnaire and hand-arm vibration was measured. Part two involved a set of hand clinical examinations (Purdue pegboard, Semmes-Weinstein monofilament and two-point discrimination tests) carried out for neurological component severity staging. LVD for each worker was calculated from data gathered in part one. For workers who had neurological symptoms, staging according to Stockholm workshop scales was done according to part two data. The strength of correlation between LVD and neurological stages was then determined using Spearman correlation. Results. Prevalence of neurological component was 37%. Spearman correlation between LVD and the neurological stages showed a moderate positive correlation. Conclusion. Cumulative lifetime exposure to hand-transmitted vibration is likely to be related to neurological severity of HAVS and therefore must be considered when assessing workers' exposure to hand-arm vibration.

The Effects of Wet Cupping Therapy on Fasting Blood Sugar, Renal Function Parameters, and Endothelial Function: A Single-arm Intervention Study.

OBJECTIVES: Despite being recognized worldwide as an alternative therapy in treating various chronic diseases and pain, the mechanism of wet cupping is still not well understood. The purpose of this study was to evaluate fasting blood sugar (FBS), renal function parameters, and endothelial function changes following wet cupping in healthy individuals. METHODS: We conducted a single-arm intervention study at the Clinical Lab of Community Medicine, Universiti Sains Malaysia, and included 31 healthy individuals aged between 30 and 60 years old. Wet cupping therapy was performed at five treatment points at the beginning of the study and repeated after three months. Health outcomes at baseline, one, three, and four months were assessed for FBS, renal function parameters (urea, creatinine, and uric acid), systolic blood pressure (SBP), and von Willebrand factor (vWF). RESULTS: Forty-five percent of participants were female, and the mean age of study participants was 44.9±6.4 years. Wet cupping therapy significantly reduced FBS, serum urea, and serum creatinine at one, three, and four months compared with baseline values. Serum uric acid and SBP showed a significant reduction at one and four months compared with baseline. The vWF (a measure of endothelial function) had a 4.0% reduction at four months compared to baseline, with a mean difference of 5.3 (95% confidence interval (CI): 2.20 = 8.55; p = 0.002). CONCLUSIONS: This study provides preliminary support that repeated wet cupping therapy enhances body health status; thus, it could be an effective complementary medicine in disease prevention.

Pelvic Floor Muscle Exercise Education and Factors Associated with Implementation among Antenatal Women in Hospital Universiti Sains Malaysia.

BACKGROUND: Pelvic floor muscle exercise is effective for pelvic floor muscle dysfunction. Despite the high prevalence of pelvic floor muscle dysfunction in women in the community, pelvic floor muscle exercise recognition is low in Malaysian society; thus, this intervention is not frequently used . This study assessed the knowledge of, attitudes towards, and use of pelvic floor muscle exercise among antenatal women before and after educational classes. The study also determined factors associated with exercise practice. METHODS: An interventional study was conducted in 121 antenatal women selected through systematic random sampling between June and December 2010. Baseline knowledge of, attitude towards, and practice of pelvic floor muscle exercise were assessed using self-administered validated questionnaires at first visit and at 2 months postpartum. All participants attended two exercise education classes on their next two visits before delivery. A paired ttest and multivariate analysis were used for data evaluation. RESULTS: The mean pre-intervention scores for knowledge, attitudes, and practice were 24.98, 24.25, and 3.51, respectively, with statistically significant mean score increments after intervention (P<0.001). The mean differences were 4.67 (95% confidence interval [CI], 3.86-5.49), 3.77 (95% CI, 3.05-4.50) and 3.45 (95% CI, 2.90-4.00) for knowledge, attitudes, and practice, respectively. Lack of baseline information on pelvic floor muscle exercise was significantly associated with practice change following an educational class. CONCLUSION: Education is effective in improving knowledge of, attitude towards, and practice of pelvic floor muscle exercise. There is a need for greater effort to increase exercise awareness in our community, especially during antenatal class.

The Effectiveness of a Voice Care Program Among Primary School Teachers in Northeastern Malaysia.

OBJECTIVES: We sought to determine the effectiveness of a voice care program among primary school teachers in a northeastern district in Malaysia. METHODS: We conducted a randomized community trial in eight primary schools in a northeastern district in Malaysia. The self-administered and validated Malay-Voice Handicap Index-10 (M-VHI-10) questionnaire was used to assess overall voice handicap scores pre-intervention and eight weeks post-intervention. Teachers with a score of five or more (n = 86) were randomized into intervention (n = 41) and control groups (n = 45). The intervention group received portable voice amplifiers and vocal hygiene instruction, which was delivered by lectures and a booklet. The control group was not prescribed any intervention. RESULTS: The sociodemographic, lifestyle, and occupational characteristics of the teachers (except maximum number of students per class) were similar between both groups. The baseline M-VHI-10 scores between both groups were also comparable. After the intervention phase, there was a significant effect observed in the total M-VHI-10 scores (p = 0.021, F-stat (df): 5.33 (1,79)) between both groups after controlling for the maximum number of students per class. CONCLUSIONS: Our results support the use of voice amplification in adjunct with vocal hygiene instruction as a prevention and treatment modality to reduce voice handicap among teachers. Our study demonstrated encouraging evidence on the low-cost voice care program as well as the success of group and workplace-based approaches in the school setting.
