The COVID-19 pandemic has intensified the use of screens, especially among students. This study aimed to find the association between screen time and the level of perceived stress among students of University of Peradeniya during COVID-19 pandemic. Methods: In this cross-sectional study, a pretested questionnaire consisting of the 18-item screen time questionnaire and perceived stress scale (PSS) questionnaire was distributed among all the undergraduate students of the University of Peradeniya at the time of the study, via email, and a representative sample (N = 387, mean age = 22.964 ± 1.818 years) was selected from the responses received. Results: Mean screen time was found to be 13h 27 min± 4h 52 min, and the most used screen type among males was laptop/computer, and among females, smartphone. The mean perceived stress of the sample was 20.499 ± 5.393. Spearman correlation for screen time an...

Research paper thumbnail of Effect of balance training on footwork performance in badminton: An interventional study

Efficient movement in badminton court entails reaching the shuttlecock in as few steps as possible while maintaining good balance. Balance training is an unexplored component in badminton training protocol, though balance is important in injury prevention and performance enhancement. We aimed to investigate the effectiveness of balance training on sport-specific footwork performance of school-level competitive badminton players. We conducted a controlled trial involving 20 male badminton players (age 12.85±0.67 years). Participants were stratified according to their level of performance in the game, and payers from each stratum were randomly assigned to control and intervention groups. The control group (n = 8) engaged in 2 hours of ordinary badminton training, whereas the intervention group (n = 12) underwent 30 minutes of balance training followed by 1 hour and 30 minutes of ordinary badminton training, 2 days per week for 8 weeks. We tested the participants at baseline and after 8 weeks for static balance (Unipedal Stance Test), dynamic balance (Star Excursion Balance Test) and sport-specific footwork performance (shuttle run time and push-off times during stroke-play). On pre-vs. post-intervention comparisons, both groups improved in static balance (eyes opened) (p<0.05), but only the intervention group improved in dynamic balance (p = 0.036) and shuttle-run time (p = 0.020). The intervention group also improved push-off times for front forehand (p = 0.045), side forehand (p = 0.029) and rear around-the-head shots (p = 0.041). These improvements in push-off times varied between 19-36% of the baseline. None of the footwork performance measures significantly improved in the control group. Our findings indicate that incorporating a 30-minute balance training program into a regular training schedule improves dynamic balance, and on-court sport-specific footwork performance in adolescent competitive badminton players, after 8 weeks of training.

Previous studies have found that many factors are associated with flatfoot. The objective of the present study was to investigate the prevalence of flatfoot and its association with age, gender and BMI in group of 6-10 aged children in Central province of Sri Lanka. Method: A total of 722 children aged 6 to 10 were used to assess normalize navicular height using two clinical measurements (navicular height, truncated foot length). Weight and height of the subjects were measured to calculate body mass index. Age and gender of the children were also recorded. Calculated normalize navicular heights were plotted in a distribution curve and area under the curve between +1SD and-1SD was considered as normal foot. Area under the curve which is left to the-1SD was considered as flatfoot. Results: Overall prevalence of flatfoot among 6-10 aged children in the present sample was 16.06%. The prevalence of flatfoot in 6,7,8,9 and 10 aged children were 26.35%, 16.19%, 12.75%, 13.57% and 11.1%, respectively. Prevalence of flatfoot was high in overweight children (21.05%). Prevalence of flatfoot among males and females were 47% and 53%, respectively. Conclusion: This study suggests that there is a significant association between flatfoot and age (p<0.05). Prevalence of flat foot decreases with advancing age. Furthermore, there is a significant association between flatfoot and body mass index (p<0.05). Prevalence of flatfoot is higher in overweight children than normal weight and underweight children. There is no significant association between flatfoot and gender.

Pathophysiology of badminton injuries is reported to be dominated by overuse injuries and upper limb accounts for approximately one third of overuse injuries mainly to tendons, which are known as tendinopathies. A descriptive cross sectional study was conducted including 25 badminton players, to investigate occurrence and associated factors of elbow, wrist and hand tendinopathies in badminton players. A interviewer administered questionnaire was used to obtain descriptive data (age, sex, level of the player, standards of warm up and cool down, components of training schedule (ex. strengthening exercises, flexibility exercises), intensity of practice (Duration, frequency), duration of playing of the racquet sport and previous injuries to upper limb) from the players. Player’s height, weight, pain response, palm length, finger length, thumb length, palm width, grip strength, active/passive and painful/ pain free Range of motions o...

The high physical demands for badminton suggest that badminton players may have frequent occurrences of badminton related injuries. The present study aimed to investigate the pattern of badminton related injuries among elite junior badminton players of Kandy district, Sri Lanka. A descriptive cross sectional study was conducted using an assessment form which consisted of two parts. Sixty two badminton players were included in the study. Among them, 34 players were males and 28 players were females. Age of the players was distributed from 8 years to 17 years. An overall injury prevalence of 33.87% was recorded. Injury prevalence among males was 44.12% and injury prevalence among females was 39.29%. When considering the injury pattern according to location of injuries, lower limb was reported as the most susceptible part for injuries (62.5%). Most of the injuries among males were ankle injuries (40%) and most of the injuries among...

In Sri Lanka the concept of community physiotherapy has not emerged yet. The present study aimed to identify the need for ‘community physiotherapy service’ in Kandy district, Sri Lanka. Methods: A community service projection community based rehabilitation, of three years was conducted by the department of physiotherapy, faculty of allied health sciences, University of Peradeniya, Sri Lanka in 2017-2019 in collaboration with department of social service and social welfare of Kandy district secretariat, Sri Lanka.Results: One hundred and seventy participants with physical disabilities were included in the study 94 (55.29%) were males (mean age; 33.57 (SD ±23.17) and 76 (44.71%) were females (mean age; 33.14 (SD ±24.98). The pediatric population was 41.76% (N=71) followed by 38.82% of adults (N=66) and 19.41% of elderly patients (N=33) of the total population. The high...

These high physical demands for badminton suggest that injuries related to badminton among players may have a frequent occurrence. Therefore, the epidemiology of badminton related injuries had been studied among competitive (elite and sub elite) players and recreational players of all ages in many countries. Therefore, the current review discusses the literature on epidemiology (incidence/prevalence, severity, location, type, competition/practice injuries) of badminton related injuries among competitive badminton players in diverse populations. The search strategy included PubMed, Science Direct and Google Scholar search from the year 1979. Fourteen (14) studies which have investigated epidemiology of badminton injuries were found. Injury incidence/prevalence was diverse in different populations. Majority of badminton related injuries are recoded as mild injuries. Lower limb was recorded as the most susceptible region for badminton related injuries. Overuse injuries have been recorded as the dominant type of injury. Dominance of competition/practice injuries was diverse in different populations. It is evident that the epidemiology of badminton related injuries shows a population difference. Investigating the epidemiology of injuries in a given population is required to understand the extent of injuries and identify the priority areas to implement specific injury prevention progammes.
