The street vendors in Malaysia are at an increased risk of developing respiratory symptoms owing to the continuous exposure to road dust, vehicle emissions, extreme weather conditions, and air pollutants from industrial sites. Hence, the current study aimed to establish the prevalence of respiratory symptoms and the risk factors associated with it among street food vendors in Klang Valley, Malaysia through a cross-sectional study among 237 street food vendors. The socio-demographic data, work characteristics, and information on respiratory symptoms were collected using a self-administered questionnaire. The data analysis was done by using the Chi-square test of association and frequency distribution. The study results revealed that the most frequently reported respiratory symptoms among the street food vendors were sore throat (30.8%), followed by cough (29.1%). No significant association was found between age, gender, duration of job and cough, sputum production, breathing difficulty, chest pain, irritated nose, and sore throat. A statistically significant association was found between working hours and sputum production (p=0.014). Further, the working hours were significantly associated with breathing difficulty (p=0.011). A significant association was also found between the type of cooking fuel used and the presence of cough (p=0.001). Results of this study demonstrated a positive association between work-related risk factors such as working hours with breathlessness and sputum production, and also between cough and the type of cooking fuel used. Based on the aforementioned findings, various control measures such as regular monitoring of lung functions and health education programs can be undertaken. Moreover, vendors need to consider using clean fuels instead of charcoal.

AIMS: Based on the limited evidence available about the intrinsic factors causing lower extremity injuries among Malaysian badminton players, this study was aimed to determine the relationship of demographic and physical characteristics to lower extremity injuries in young badminton players.METHODS: A cross-sectional study included badminton players between 14 and 24 years of age, categorized into case and control groups. Participants diagnosed with lower limb injuries were designated as cases, and those with no reported injuries were designated as controls. Personal information including demographic data, level of athlete and injury history was collected using a questionnaire. Independent t-test was used to analyze the differences between intrinsic characteristics in cases and controls. Pearson's χ2 was applied to evaluate the association between risk factors and general lower limb injuries, knee injuries and ankle injuries, with 95% confidence interval (CI). A p value of ≤0.05 was considered significant.RESULTS: A total of 106 young badminton players (83 males, 23 females) were recruited, of whom 42 participants were allocated as the case group, and 64 participants were allocated as the control group. A total of 60 lower extremity injuries were reported among the 42 players of the case group. The overall mean age of the sample was 18.7±5 years (minimum 14 years and maximum 24 years). Mean age of the participants in the case group was 16.92±2.99 years. The most common injuries reported were ankle joint injuries, followed by knee and hip injuries. Participants of the younger age group (14-19 years old) were found to have a higher risk for lower extremity injures compared to those of the older age group (20-24 years old) (odds ratio [OR], 3.39; 95%CI, 1.15-10.01; p=0.023). Increased true limb length discrepancy was identified among the participants with lower extremity injuries (OR, 4.57, 95%CI, 1.2-17.24; p=0.016) and this discrepancy was strongly associated with ankle injuries (OR, 7.25; 95%CI, 1.85-28.57; p=0.002). There was no significant relationship between lower extremity injuries and gender, limb dominance or Q-angle.CONCLUSIONS: Lower extremity injuries in young badminton players were predominantly located in ankle and knee joints. Younger age and increase in true limb length discrepancy were identified as risk factors for lower extremity injuries in the study sample.

BACKGROUND: Athletes with chronic ankle pain (CAP) are more inclined to suffer from physical and psychological pain depending on the severity of the injuries, which might trigger the powerless feeling on future sports participation. Therefore, an efficient and simple method is useful to integrate into conventional physiotherapy (CP) for maintaining mental wellness. OBJECTIVE: This research aimed to verify the effects and progress of video-guided deep breathing (DB) integrated into CP through study on the changes of alpha waves and pain scale. METHODS: Alpha waves were recorded using an electroencephalogram (EEG) and a visual analogue scale (VAS) to assess pain intensity before and after the intervention (6 weeks). Thirty CAP participants were recruited and randomly assigned to two groups: group A for video-guided DB integration into their CP and group B for CP. The effects of pre and post intervention were analyzed using a paired t-test with statistical significance set at p< 0.05. RESULTS: Profound results from the research have shown that the participants who received both the DB+CP revealed a significant increase in alpha wave (p< 0.05) at occipital region. CONCLUSION: The significant result reveals an increase in alpha waves in the occipital region after 6 weeks and indicates that the video-guided DB with a smartphone application is able to produce a change in CAP participants. This supports the DB integration to the CP for altering the pain perception.
