Paediatric injuries due to home treadmill use: an emerging problem

Recommendations for Resuming PA after Prolonged Rest in Children and Adolescents: A Systematic Integrative Review of Relevance for Immunity

This systematic integrative review aims to summarize the protective effect of PA on children and adolescents, with special reference to the immune system. Periods of prolonged inactivity in children and adolescents are rare and due to exceptional events, such as illness or environmental circumstances, e.g., natural disasters, wars, or epidemics. The recent COVID-19 pandemic forced billions of children in developmental ages into inactivity. This exceptional event was the reason for studying the compensational behavioral strategies adopted by children and adolescents to counteract physical inactivity. Several studies showed the rise of spontaneous physical activity (PA) among children and adolescents to compensate for sedentarism. However, for some children, sedentarism could in turn foster other sedentarism. With the restart of "normal daily life" worldwide, a question is posed on both how to resume PA without causing damage and how to improve the immune response. Some key points emerged from the literature. Children must resume PA gradually using different methods, considering age, sex, health status, and the presence of overweight conditions. Immunity can be stimulated with PA by aerobic exercise, resistance training, flexibility exercise, relaxation, and coordinative exercises.

Early wound repair versus later scar repair in children with treadmill hand friction burns

The incidence of pediatric treadmill hand friction burns has been increasing every year. The injuries are deeper than thermal hand burns, the optimal treatment remains unclear. This was a retrospective study of children who received surgery for treadmill hand friction burns from January 1, 2015, to December 31, 2019, in a single burn center. A total of 22 children were surveyed. The patients were naturally divided into two groups: the wound repair group (13 patients), which was admitted early to the hospital after injury and received debridement and vacuum sealing drainage initially, and a full-thickness skin graft later; and the scar repair group (9 patients), in which a scar contracture developed as a result of wound healing and received scar release and skin grafting later. The Modified Michigan Hand Questionnaire score in the wound repair group was 116.31 ± 10.55, and the corresponding score in the scar repair group was 117.56 ± 8.85 (P>0.05), no statistically significant difference. The Vancouver Scar Scale score in the wound repair group was 4.15 ± 1.21, and the corresponding score in the scar repair group was 7.22 ± 1.09 (P<0.05). Parents were satisfied with the postoperative appearance and function of the hand. None in the two groups required secondary surgery. If the burns are deep second degree, third degree, or infected, early debridement, vacuum sealing drainage initially, and a full-thickness skin graft can obviously relieve pediatric pain, shorten the course of the disease, and restore the function of the hand as soon as possible.

Treadmill Hand Injuries Among Children: A Retrospective Case Series From Hospitalized Patients

Background: With the progress of modernization, treadmill hand injury in pediatric population is taking on a global trend in recent years. The purpose of this study was to investigate the epidemiology and clinical features in a developing country, thereby providing some experience in the treatment and prevention of this particular type of injury. Methods: A 5-year retrospective review of patients with treadmill hand injury in Burn and Plastic Surgery ward at Children' Hospital of Chongqing Medical University was conducted. Demographics, injury details, therapy performed, length of hospital stay, complications, and outcome were analyzed. Results: Forty-six patients were surveyed, with a mean age of 3.5 ± 2.0 years old, including 24 males and 22 females. Injuries (77.8%) occurred between dinner to bedtime, and 95.7% happened indoors. Fingers were the most vulnerable part, of which the middle finger, ring finger, and index finger were the top three ones. The mean body surface area (BSA%) was 0.3 ± 0.2, but at least in deep dermal. Dressing changes, full-thickness skin grafts (FTSG), and Negative Pleasure Wound Therapy (NPWT) assisted FTSG were performed. The scar contracture, as the most severe complication, occurred in 26 patients, of which 22 originally received dressing changes at the time of injury. Conclusion: Treadmill hand injury in children should be highly regarded. Compared with conservative dressing changes, surgical intervention from a professional team may achieve more satisfactory prognosis and fewer complications. A prevention strategy based on "Time-Space-Person" was summarized according to its epidemiological characteristics, may help to decrease the incidence of this specific type of injury theoretically.

Treadmill associated head injuries on the rise: an 18 year review of U.S. emergency room visits

OBJECTIVE

The treadmill is the most commonly used aerobic exercise equipment with studies showing many gym-related injuries are attributed to treadmills. The purpose of this study is to examine the incidence of treadmill-associated head injuries within the US.

METHODS

Retrospective data from 1997 to 2014 was collected via the National Electronic Injury Surveillance System, which provides annual es7timates of injuries associated with consumer products. Patients over 18 years who sustained treadmill-associated head injuries were included, and the estimated annual incidence was determined.

RESULTS

An estimated 4929 patients presented to US emergency departments with a head injury while exercising on a treadmill between 1997 and 2014. A >1000% increase in the number of head injuries was observed over the study period (p-value <0.001). Patients over 50 had a 14 times greater risk of admission than younger patients (p-value <0.001). Injuries were greater in women than men.

CONCLUSION

Our study demonstrates a significant increase treadmill-associated head injuries from 1997 to 2014. This phenomenon is most pronounced in older and female populations. The exact etiology of this large increase remains unclear. Education on the proper use of treadmills as well as further investigation into the cause of the increase are warranted.

Emergency department-reported injuries associated with mechanical home exercise equipment in the USA

The goal of this study was to generate national estimates of injuries associated with mechanical home exercise equipment, and to describe these injuries across all ages. Emergency department (ED)-treated injuries associated with mechanical home exercise equipment were identified from 2007 to 2011 from the National Electronic Injury Surveillance System. Text narratives provided exercise equipment type (treadmill, elliptical, stationary bicycle, unspecified/other exercise machine). Approximately 70 302 (95% CI 59 086 to 81 519) mechanical exercise equipment-related injuries presented to US EDs nationally during 2007-2011, of which 66% were attributed to treadmills. Most injuries among children (≤4 years) were lacerations (34%) or soft tissue injuries (48%); among adults (≥25 years) injuries were often sprains/strains (30%). Injured older adults (≥65 years) had greater odds of being admitted, held for observation, or transferred to another hospital, compared with younger ages (OR: 2.58; 95% CI 1.45 to 4.60). Mechanical exercise equipment is a common cause of injury across ages. Injury awareness and prevention are important complements to active lifestyles.
