The effect of rapid weight loss on sports injury in elite taekwondo athletes.

OBJECTIVES: The purpose of this study was to reveal the relationship of injury patterns between normal training period and weight loss period in Korea elite taekwondo athletes. METHODS: Since 2021, data for elite taekwondo athletes have been collected prospectively by the Korean Training Institute, there were 102 male and 95 female. The data were classified by sex, weight class, injury location, injuries during the normal training and weight loss periods. The χ2 test was used to compare groups. The injury incidence rates were calculated as the number of injuries per 1,000 hours of training. RESULTS: A total of 703 injuries were recorded during normal training, and total of 149 injuries were recorded during the weight loss period. Taekwondo athletes showed a higher incidence of during the weight loss period than during the normal training period (3.66 VS 6.88; p < 0.001). The body parts affected by injury differed significantly between the normal training period and weight loss period (p = 0.033). Injury to the lower extremities or to the head and neck was relatively higher during the normal training period, while injury to the trunk and upper extremities was relatively higher during the weight loss period. Muscle, ligament, and bone injuries were common during both the normal training and weight loss periods. Level I injuries were relatively more frequent during normal training, while level II and III injuries were relatively more frequent during weight loss (p < 0.001). CONCLUSION: Rapid weight loss is related to the injury patterns in taekwondo athletes. Injury incidence rate increases during rapid weight loss periods. Moreover, the injury site and injury severity depend on during normal training and during the weight loss period.

Auxetic structures used in kinesiology tapes can improve form-fitting and personalization.

Each year 65% of young athletes and 25% of physically active adults suffer from at least one musculoskeletal injury that prevents them from continuing with physical activity, negatively influencing their physical and mental well-being. The treatment of musculoskeletal injuries with the adhesive elastic kinesiology tape (KT) decreases the recovery time. Patients can thus recommence physical exercise earlier. Here, a novel KT based on auxetic structures is proposed to simplify the application procedure and allow personalization. This novel KT exploits the form-fitting property of auxetics as well as their ability to simultaneously expand in two perpendicular directions when stretched. The auxetic contribution is tuned by optimizing the structure design using analytical equations and experimental measurements. A reentrant honeycomb topology is selected to demonstrate the validity of the proposed approach. Prototypes of auxetic KT to treat general elbow pains and muscle tenseness in the forearm are developed.

Extracorporeal Shockwave Therapy in the Management of Sports Medicine Injuries.

ABSTRACT: Treatment of musculoskeletal conditions in athletes with extracorporeal shockwave therapy (ESWT) is gaining popularity as greater evidence supports its use. ESWT protocols (describing energy flux density, number of impulses, type of shockwave (focused or radial), number/frequency/duration of treatment session, area of application, and postprocedural therapy protocols) can be adjusted in the clinical setting. Protocols vary across studies, and optimal protocols for most indications are yet to be determined. ESWT can safely be used to treat various musculoskeletal conditions in athletes, including rotator cuff tendinopathy, lateral elbow epicondlyopathy, greater trochanteric pain syndrome, hamstring tendinopathy, patellar tendinopathy, Achilles tendinopathy, other tendinopathies, plantar fasciopathy, bone stress injuries, and medial tibial stress syndrome. ESWT can be used to treat in-season athletes, as it often requires no/minimal time away from sport and may result in rapid benefits. ESWT should be used in conjunction with physical therapy to facilitate longer-term gains in function and to optimize healing.

Five-Year Management of Vascular Injuries of the Extremities in the "Real-World" Setting in Northeastern Greece: The Role of Iatrogenic Traumas.

BACKGROUND: Vascular trauma comprises a diagnostic and surgical challenge. Aim of this study was to present the vascular traumas treated in our Tertiary Hospital during the last 5 years. METHODS: We retrospectively reviewed the surgical records of our vascular department and documented the site and type of vascular injuries of the extremities along with the concurrence of musculoskeletal injuries. The type and outcome of surgical interventions were also recorded. RESULTS: Fifty-eight cases of vascular trauma were recorded (39 in the upper and 19 in the lower extremities). Overall, iatrogenic traumas accounted for 41.3% of cases. The arterial injuries of the upper limb were blunt and penetrating in 27% and 67%, respectively. The most affected artery in the upper limb was the radial artery (37.8%), followed by the ulnar artery (27%) and the brachial artery (24.3%). Orthopedic injuries were recorded in 19% of patients. Management involved simple revascularization, bypass operations, patch arterioplasty and endovascular management in 48.7%, 33.3%, 5.1%, and 5.1%, respectively. The most affected site in the lower extremity was the common femoral artery (36.8%) followed by the popliteal artery (21%). Bone fractures were reported in 5 cases (26.3%). The surgical management involved bypass, simple revascularization, patch arterioplasty in 42.1%, 26.3%, and 21%, respectively. Endovascular management was performed in 10.5%. CONCLUSIONS: A considerable percentage of iatrogenic vascular injuries was recorded, affecting both the upper and lower limbs. Despite the trend toward centralization of vascular services, a basic service of vascular surgery should be available in most sites to ensure that patients with vascular injuries receive fast and appropriate care.

Nonpharmacologic and Pharmacologic Management of Acute Pain From Non-Low Back, Musculoskeletal Injuries in Adults: A Clinical Guideline From the American College of Physicians and American Academy of Family Physicians.

DESCRIPTION: The American College of Physicians (ACP) and American Academy of Family Physicians (AAFP) developed this guideline to provide clinical recommendations on nonpharmacologic and pharmacologic management of acute pain from non-low back, musculoskeletal injuries in adults in the outpatient setting. The guidance is based on current best available evidence about benefits and harms, taken in the context of costs and patient values and preferences. This guideline does not address noninvasive treatment of low back pain, which is covered by a separate ACP guideline that has also been endorsed by AAFP. METHODS: This guideline is based on a systematic evidence review on the comparative efficacy and safety of nonpharmacologic and pharmacologic management of acute pain from non-low back, musculoskeletal injuries in adults in the outpatient setting and a systematic review on the predictors of prolonged opioid use. We evaluated the following clinical outcomes using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system: pain (at ≤2 hours and at 1 to 7 days), physical function, symptom relief, treatment satisfaction, and adverse events. TARGET AUDIENCE AND PATIENT POPULATION: The target audience is all clinicians, and the target patient population is adults with acute pain from non-low back, musculoskeletal injuries. RECOMMENDATION 1: ACP and AAFP recommend that clinicians treat patients with acute pain from non-low back, musculoskeletal injuries with topical nonsteroidal anti-inflammatory drugs (NSAIDs) with or without menthol gel as first-line therapy to reduce or relieve symptoms, including pain; improve physical function; and improve the patient's treatment satisfaction (Grade: strong recommendation; moderate-certainty evidence). RECOMMENDATION 2A: ACP and AAFP suggest that clinicians treat patients with acute pain from non-low back, musculoskeletal injuries with oral NSAIDs to reduce or relieve symptoms, including pain, and to improve physical function, or with oral acetaminophen to reduce pain (Grade: conditional recommendation; moderate-certainty evidence). RECOMMENDATION 2B: ACP and AAFP suggest that clinicians treat patients with acute pain from non-low back, musculoskeletal injuries with specific acupressure to reduce pain and improve physical function, or with transcutaneous electrical nerve stimulation to reduce pain (Grade: conditional recommendation; low-certainty evidence). RECOMMENDATION 3: ACP and AAFP suggest against clinicians treating patients with acute pain from non-low back, musculoskeletal injuries with opioids, including tramadol (Grade: conditional recommendation; low-certainty evidence).

Musculoskeletal injuries in taekwondo athletes: a nationwide study in Portugal.

OBJECTIVE: Taekwondo is a martial art that emphasizes blows using the feet and fists, and it is characterized by direct and continuous body contact, which subjects their practitioners to a higher number of injuries. This study aimed to determine the incidence of musculoskeletal injuries in Portuguese taekwondo athletes and analyze its associated factors. METHODS: The sample included 341 taekwondo athletes, aged between 4 and 62 years (18.77±12.77 years), 237 (69.5%) were male, and 104 (30.5%) female. A questionnaire was administered at a national level in taekwondo training and competitions via interview. RESULTS: One hundred and thirty-two (38.7%) taekwondo athletes reported having suffered an injury since they began their practice, totaling 294 injuries. Seventy-six (22.3%) athletes had an injury in the previous 12-months period, with a total of 112 injuries. There were 2.15 injuries per 1,000 hours of taekwondo training. The most common of all injuries was muscle injury (strain, contusion) (58.6%), in the foot and fingers (18.9%). The attack technique (28.8%) was the most prevalent injury mechanism. Adult athletes presented a higher risk of sustaining taekwondo-related injuries than adolescents (odds ratio = 3.91; 95%CI: 1.13-13.55; p=0.032), and athletes who trained more than 1 hour had a risk 4.20 times greater (95%CI: 1.44-12.29; p=0.009) than those who trained up to 1 hour per session. CONCLUSIONS: Injuries were frequent among Portuguese taekwondo athletes, with specific body areas affected, mainly caused by the attack technique. It is necessary to create injury prevention strategies, including specific training and the use of protective equipment.

Can an Integrative Care Approach Improve Physical Function Trajectories after Orthopaedic Trauma? A Randomized Controlled Trial.

BACKGROUND: Orthopaedic trauma patients frequently experience mobility impairment, fear-related issues, self-care difficulties, and work-related disability []. Recovery from trauma-related injuries is dependent upon injury severity as well as psychosocial factors []. However, traditional treatments do not integrate psychosocial and early mobilization to promote improved function, and they fail to provide a satisfying patient experience. QUESTIONS/PURPOSES: We sought to determine (1) whether an early psychosocial intervention (integrative care with movement) among patients with orthopaedic trauma improved objective physical function outcomes during recovery compared with usual care, and (2) whether an integrative care approach with orthopaedic trauma patients improved patient-reported physical function outcomes during recovery compared with usual care. METHODS: Between November 2015 and February 2017, 1133 patients were admitted to one hospital as orthopaedic trauma alerts to the care of the three orthopaedic trauma surgeons involved in the study. Patients with severe or multiple orthopaedic trauma requiring one or more surgical procedures were identified by our orthopaedic trauma surgeons and approached by study staff for enrollment in the study. Patients were between 18 years and 85 years of age. We excluded individuals outside of the age range; those with diagnosis of a traumatic brain injury []; those who were unable to communicate effectively (for example, at a level where self-report measures could not be answered completely); patients currently using psychotropic medications; or those who had psychotic, suicidal, or homicidal ideations at time of study enrollment. A total of 112 orthopaedic trauma patients were randomized to treatment groups (integrative and usual care), with 13 withdrawn (n = 99; 58% men; mean age 44 years ± 17 years). Data was collected at the following time points: baseline (acute hospitalization), 6 weeks, 3 months, 6 months, and at 1 year. By 1-year follow-up, we had a 75% loss to follow-up. Because our data showed no difference in the trajectories of these outcomes during the first few months of recovery, it is highly unlikely that any differences would appear months after 6 months. Therefore, analyses are presented for the 6-month follow-up time window. Integrative care consisted of usual trauma care plus additional resources, connections to services, as well as psychosocial and movement strategies to help patients recover. Physical function was measured objectively (handgrip strength, active joint ROM, and Lower Extremity Gain Scale) and subjectively (Patient-Reported Outcomes Measurement Information System-Physical Function [PROMIS®-PF] and Tampa Scale of Kinesiophobia). Higher values for hand grip, Lower Extremity Gain Scale (score range 0-27), and PROMIS®-PF (population norm = 50) are indicative of higher functional ability. Lower Tampa Scale of Kinesiophobia (score range 11-44) scores indicate less fear of movement. Trajectories of these measures were determined across time points. RESULTS: We found no differences at 6 months follow-up between usual care and integrative care in terms of handgrip strength (right handgrip strength ß = -0.0792 [95% confidence interval -0.292 to 0.133]; p = 0.46; left handgrip strength ß = -0.133 [95% CI -0.384 to 0.119]; p = 0.30), or Lower Extremity Gain Scale score (ß = -0.0303 [95% CI -0.191 to 0.131]; p = 0.71). The only differences between usual care and integrative care in active ROM achieved by final follow-up within the involved extremity was noted in elbow flexion, with usual care group 20° ± 10° less than integrative care (t [27] = -2.06; p = 0.05). Patients treated with usual care and integrative care showed the same Tampa Scale of Kinesiophobia score trajectories (ß = 0.0155 [95% CI -0.123 to 0.154]; p = 0.83). CONCLUSION: Our early psychosocial intervention did not change the trajectory of physical function recovery compared with usual care. Although this specific intervention did not alter recovery trajectories, these interventions should not be abandoned because the greatest gains in function occur early in recovery after trauma, which is the key time in transition to home. More work is needed to identify ways to capitalize on improvements earlier within the recovery process to facilitate functional gains and combat psychosocial barriers to recovery. LEVEL OF EVIDENCE: Level II, therapeutic study.

RESUMO INTRODUÇÃO O Taekwondo consiste numa arte marcial que enfatiza os golpes com os pés e punhos, sendo caracterizada pelo contato corporal direto e contínuo, fatores que podem ocasionar lesões. O objetivo do estudo foi determinar a incidência de lesões musculoesqueléticas em atletas portugueses de taekwondo e analisar os fatores associados. MÉTODOS A amostra foi constituída por 341 atletas de taekwondo, com idades entre 4 e 62 anos (18,77±12,77), sendo 237 (69,5%) do sexo masculino. O instrumento de medida consistiu num questionário, aplicado sob a forma de entrevista, em nível nacional. RESULTADOS Cento e trinta e dois (38,7%) atletas relataram terem sofrido lesões desde que iniciaram a prática, totalizando 294 lesões. Setenta e seis (22,3%) atletas referiram presença de lesões no período de 12 meses, totalizando 112 lesões. Foram registradas 2,15 lesões por 1.000 horas de treinamento de taekwondo. O tipo de lesão mais frequente foi a lesão muscular (57,7%) e as localizadas no pé e dedos (18,9%). A técnica de ataque (28,8%) foi o mecanismo de lesão mais prevalente. Os adultos apresentaram maior risco de sofrer lesões comparados aos adolescentes (odds ratio = 3,91; IC 95%: 1,13-13,55; p=0,032), e os atletas que treinaram mais de uma hora tiveram um risco de 4,20 (IC 95%: 1,44-12,29; p=0,009) do que aqueles que treinaram até uma hora por sessão. CONCLUSÕES Os dados do estudo revelaram que as lesões foram frequentes em atletas portugueses de taekwondo, com áreas corporais específicas afetadas, e causadas principalmente pela técnica de ataque. Torna-se necessário elaborar estratégias de prevenção de lesões, incluindo treinamentos específicos e uso de material de proteção.

Hyperbaric Oxygen Therapy in Sports Musculoskeletal Injuries.

Hyperbaric oxygen therapy (HBOT) is a well-established treatment for a variety of conditions. Hyperbaric oxygen therapy is the administration of 100% oxygen breathing in a pressure vessel at higher than atmospheric pressure (1 atmosphere absolute = 101 kPa). Typically, treatment is given daily for between 1 and 2 h at pressures of 2.0 to 2.8 ATA, depending on the indication. Sporting injuries are often treated over 3 to 10 sessions. Hyperbaric oxygen therapy has been documented to be effective and is approved in 14 medical indications by the Undersea and Hyperbaric Medical Society, including, but not limited to, carbon monoxide poisoning, compromised skin grafts and flaps, crush injuries, necrotizing soft tissue infections, and nonhealing ulcers with arterial insufficiencies. Recently, HBOT for sports musculoskeletal injuries is receiving increased attention. Hyperbaric oxygen therapy may allow injured athletes to recover faster than normal rehabilitation methods. Any reduction in collegiate and professional athletes' rehabilitation period can be financially significant for top-level sports teams; however, further research is required to confirm HBOT's benefits on sports musculoskeletal injuries. The purpose of this review to discuss the current understanding of HBOT as a treatment modality for common musculoskeletal injuries in sport medicine. Moreover, we will highlight the advantages and disadvantages of this modality, as well as relevant clinical and research applications.

Current Evidence for Acute Pain Management of Musculoskeletal Injuries and Postoperative Pain in Pediatric and Adolescent Athletes.

OBJECTIVE: Sports-related injuries in young athletes are increasingly prevalent with an estimated 2.6 million children and adolescents sustaining a sports-related injury annually. Acute sports-related injuries and surgical correction of sports-related injuries cause physical pain and psychological burdens on pediatric athletes and their families. This article aims to evaluate current acute pain management options in pediatric athletes and acute pain management strategies for postoperative pain after sports-related injuries. This article will also elucidate which areas of pain management for pediatric athletes are lacking evidence and help direct future clinical trials. DATA SOURCES: We conducted a literature search through PubMed and the Cochrane Central Register of Controlled Trials to provide an extensive review of initial and postoperative pain management strategies for pediatric sports-related musculoskeletal injuries. MAIN RESULTS: The current knowledge of acute pain management for initial sports-related injuries, postoperative pain management for orthopedic surgeries, as well as complementary and alternative medical therapies in pediatric sports-related injuries is presented. Studies evaluating conservative management, enteral and nonenteral medications, regional anesthesia, and complementary medical therapies are included. CONCLUSIONS: Adequate pain management is important for sports injuries in children and adolescents for emotional as well as physical healing, but a balance must be achieved to provide acceptable pain relief while minimizing opioid use and side effects from analgesic medications. More studies are needed to evaluate the efficacy of nonopioid analgesic medications and complementary therapies in pediatric patients with acute sports-related injuries.

A prospective field study of U.S. Army trainees to identify the physiological bases and key factors influencing musculoskeletal injuries: a study protocol.

BACKGROUND: Musculoskeletal injuries (MSKIs) are common in military trainees and present a considerable threat to occupational fitness, deployability, and overall military readiness. Despite the negative effects of MSKIs on military readiness, comprehensive evaluations of the key known and possible risk factors for MSKIs are lacking. The U.S. Army Research Institute of Environmental Medicine (ARIEM) is initiating a large-scale research effort, the ARIEM Reduction in Musculoskeletal Injury (ARMI) Study, to better understand the interrelationships among a wide range of potential MSKI risk factors in U.S. Army trainees in order to identify those risk factors that most contribute to MSKI and may be best targeted for effective mitigation strategies. METHODS: This prospective study aims to enroll approximately 4000 (2000 male and 2000 female) U.S. Army trainees undergoing Basic Combat Training (BCT). Comprehensive in-person assessments will be completed at both the beginning and end of BCT. Participants will be asked to complete surveys of personal background information, medical history, physical activity, sleep behaviors, and personality traits. Physical measurements will be performed to assess anthropometrics, tibial microarchitecture and whole body bone mineral density, muscle cross-sectional area, body composition, and muscle function. Blood sampling will be also be conducted to assess musculoskeletal, genetic, and nutritional biomarkers of risk. In addition, participants will complete weekly surveys during BCT that examine MSKI events, lost training time, and discrete risk factors for injury. Participants' medical records will be tracked for the 2 years following graduation from training to identify MSKI events and related information. Research hypotheses focus on the development of a multivariate prediction model for MSKI. DISCUSSION: Results from this study are expected to inform current understanding of known and potential risk factors for MSKIs that can be incorporated into solutions that optimize Soldier health and enhance military readiness.

The epidemiology of work-related musculoskeletal injuries among chiropractors in the eThekwini municipality.

Background: Chiropractors are a unique group of health care professionals who are at risk for developing work-related musculoskeletal injuries. Diversity of daily practice imposes different physical demands on the chiropractor. This study aimed to determine the prevalence of work-related musculoskeletal injuries in chiropractors in eThekwini municipality and selected risk factors associated with these work-related musculoskeletal injuries. Methods: The design was a quantitative, cross-sectional, descriptive study utilising a self-administered questionnaire, developed specifically for this research. The questionnaire contained sections on personal and practice demographics, with questions pertaining to the single most severe work-related musculoskeletal injury, as well as the second and third most severe work-related musculoskeletal injury. Results: A response rate of 64% was obtained (n = 62). The life-time prevalence of work-related musculoskeletal injuries was 69% with a predominance of injuries to the upper extremity (50%) and lower back (28.3%). The hand/wrist was the most common anatomical site of injury (31.5%) followed by the lower back (28.3%). Number of years in practice was considered a risk factor as most injuries occurred within the first five years of practice (41.6%). The majority of injuries affected the soft tissue, including ligament sprains (27.5%) and muscle strains (26.6%) and occurred while the practitioner was performing manipulation (38.2%) of the lumbosacral (80.8%) area with the patient in the side posture (61.5%). Conclusions: The results concur with other studies on work-related musculoskeletal injuries in chiropractors and add insight into risk factors predisposing this population to injury.

Musculoskeletal and head injuries in the Ultimate Fighting Championship (UFC).

OBJECTIVES: Mixed martial arts (MMA) has witnessed a surge in popularity worldwide. This study explores the musculoskeletal and head injuries sustained in the professional fights of the Ultimate Fighting Championship (UFC), and establishes associations between injury profiles and impactful contributory factors. METHODS: The Nevada State Athletic Commission database was screened for ringside physician reports of UFC fights between January 2016 and July 2018. Information on the fighter's gender, weight, injury, way of finish, and match result were collected. Injury rates were calculated and statistical analyses were conducted to determine significant associations among variables. P-values <0.05 were considered significant (95% CI). RESULTS: A total of 291 injuries were recorded in 285 fights from nine weight divisions. The overall injury rate was 51 per 100 athletic exposures (AE). Males predominantly partook in 249 matches (87%) and had higher injury rates (54 injuries per 100 AE) than females (30 injuries per 100 AE). Decision was the most common way a match ended. Knockouts (KOs) were significantly higher in males (36%) than in females (14%, P = 0.0007). Submissions were significantly higher in females (36%) than in males (16%, P = 0.001). Head injuries (67%) were the most common injuries reported with a rate of 34 per 100 AE. Upper limb injuries were significantly higher in females (40%) than in males (14%, P = 0.0003). Lower limb injuries were significantly higher in males (19%) than in females (5%, P = 0.01). Head injuries were significantly associated with KOs (P < 0.0001). Upper limb injuries (P = 0.032) and lower limb injuries (P = 0.034) were significantly associated with matches that ended with Decision. Trend-line analyses showed that as weight division increases, overall injury rates, head injuries, lower limb injuries, and KOs' frequency increase, whereas upper limb injuries, Submission frequency, and Decision frequency decrease. CONCLUSION: MMA has a high injury rate. Gender, way of finish, and weight play an important role in predicting fight outcomes and injury profiles. Injury prevention policies must be entertained to limit injury risk in MMA.

Self-Reported Marijuana Use Is Associated with Increased Use of Prescription Opioids Following Traumatic Musculoskeletal Injury.

BACKGROUND: Cannabinoids are among the psychoactive substances considered as alternatives to opioids for the alleviation of acute pain. We examined whether self-reported marijuana use was associated with decreased use of prescription opioids following traumatic musculoskeletal injury. METHODS: Our analysis included 500 patients with a musculoskeletal injury who completed a survey about their marijuana use and were categorized as (1) never a user, (2) a prior user (but not during recovery), or (3) a user during recovery. Patients who used marijuana during recovery indicated whether marijuana helped their pain or reduced opioid use. Prescription opioid use was measured as (1) persistent opioid use, (2) total prescribed opioids, and (3) duration of opioid use. Persistent use was defined as the receipt of at least 1 opioid prescription within 90 days of injury and at least 1 additional prescription between 90 and 180 days. Total prescribed opioids were calculated as the total morphine milligram equivalents (MME) prescribed after injury. Duration of use was the interval between the first and last opioid prescription dates. RESULTS: We found that 39.8% of patients reported never having used marijuana, 46.4% reported prior use but not during recovery, and 13.8% reported using marijuana during recovery. The estimated rate of persistent opioid use ranged from 17.6% to 25.9% and was not associated with marijuana use during recovery. Marijuana use during recovery was associated with increases in both total prescribed opioids (regression coefficient = 343 MME; 95% confidence interval [CI] = 87 to 600 MME; p = 0.029) and duration of use (coefficient = 12.5 days; 95% CI = 3.4 to 21.5 days; p = 0.027) compared with no previous use (never users). Among patients who reported that marijuana decreased their opioid use, marijuana use during recovery was associated with increased total prescribed opioids (p = 0.008) and duration of opioid use (p = 0.013) compared with never users. CONCLUSIONS: Our data indicate that self-reported marijuana use during injury recovery was associated with an increased amount and duration of opioid use. This is in contrast to many patients' perception that the use of marijuana reduces their pain and therefore the amount of opioids used. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Do Technical Aids for Patient Handling Prevent Musculoskeletal Complaints in Health Care Workers?-A Systematic Review of Intervention Studies.

The physical load ensuing from the repositioning and moving of patients puts health care workers at risk of musculoskeletal complaints. Technical equipment developed to aid with patient handling should reduce physical strain and workload; however, the efficacy of these aids in preventing musculoskeletal disorders and complaints is still unclear. A systematic review of controlled intervention studies was conducted to examine if the risk of musculoskeletal complaints and disorders is reduced by technical patient handling equipment. MEDLINE®/PubMed®, EMBASE®, Allied and Complementary Medicine Database (AMED), and Cumulative Index of Nursing and Allied Health Literature (CINAHL®) were searched using terms for nursing, caregiving, technical aids, musculoskeletal injuries, and complaints. Randomized controlled trials and controlled before-after studies of interventions including technical patient handling equipment were included. The titles and abstracts of 9554 publications and 97 full-texts were screened by two reviewers. The qualitative synthesis included one randomized controlled trial (RCT) and ten controlled before-after studies. A meta-analysis of four studies resulted in a pooled risk ratio for musculoskeletal injury claims (post-intervention) of 0.78 (95% confidence interval 0.68-0.90). Overall, the methodological quality of the studies was poor and the results often based on administrative injury claim data, introducing potential selection bias. Interventions with technical patient handling aids appear to prevent musculoskeletal complaints, but the certainty of the evidence according to GRADE approach ranged from low to very low.

Musculoskeletal Injuries in Yoga.

While yoga has been widely studied for its benefits to many health conditions, little research has been performed on the nature of musculoskeletal injuries occurring during yoga practice. Yoga is considered to be generally safe, however, injury can occur in nearly any part of the body-especially the neck, shoulders, lumbar spine, hamstrings, and knees. As broad interest in yoga grows, so will the number of patients presenting with yoga-related injuries. In this literature review, the prevalence, types of injuries, forms of yoga related with injury, specific poses (asanas) associated with injury, and preventive measures are discussed in order to familiarize practitioners with yoga-related injuries.

Patient Perceptions of the Use of Medical Marijuana in the Treatment of Pain After Musculoskeletal Trauma: A Survey of Patients at 2 Trauma Centers in Massachusetts.

OBJECTIVE: To evaluate musculoskeletal trauma patients' beliefs regarding the usefulness of marijuana as a valid medical treatment for postinjury and postoperative pain and anxiety. DESIGN: Prospective survey. SETTING: Two academic Level 1 trauma centers. PATIENTS/PARTICIPANTS: Five hundred patients in an orthopedic outpatient clinic. INTERVENTION: Survey. MAIN OUTCOME MEASUREMENTS: (1) Do patients believe that marijuana can be used as medicine? (2) Do patients believe that marijuana can help treat postinjury pain? (3) Are patients comfortable speaking with their health care providers about medical marijuana? RESULTS: The majority of patients felt that marijuana could be used to treat pain (78%, 390) and anxiety (62%, 309). Most patients (60%, 302) had used marijuana at least once previously, whereas only 14% reported using marijuana after their injury. Of those who used marijuana during their recovery, 90% (63/70) believed that it reduced symptoms of pain, and 81% (57/70) believed that it reduced the amount of opioid pain medication they used. CONCLUSIONS: The majority of patients in this study believed that medical marijuana is a valid treatment and that it does have a role in reducing postinjury and postoperative pain. Those patients who used marijuana during their recovery felt that it alleviated symptoms of pain and reduced their opioid intake. Our results help inform clinicians regarding the perceptions of patients with trauma regarding the usefulness of marijuana in treating pain and support further study into the utility of medical marijuana in this population.

Work related musculoskeletal injuries sustained by Australian osteopaths: qualitative analysis of effects on practitioner health, clinical practice, and patient care.

BACKGROUND: There is limited literature that explores the experiences of osteopaths injured while engaging in clinical practice. Evidence from other similar health professions has described the numerous effects of work-related musculoskeletal injuries (WRMI). Work-related musculoskeletal injury refers to trauma to joints, ligaments, muscles and tendons resulting from injury sustained while undertaking work duties. This research aimed to gain a contextualised understanding of the experiences of osteopaths who have sustained a work-related musculoskeletal injury while performing clinical practice. METHOD: This research used a descriptive qualitative design. Participants were recruited as part of a larger cross-sectional study. Thirteen Australian osteopaths who had sustained a work-related musculoskeletal injury consented to participate in semi-structured interviews during May and June 2016. Thematic analysis was used to elicit important themes from the interview transcripts that had been recorded and transcribed verbatim. The qualitative accounts provided by the participants were coded for the impacts of their injuries on work, home life and leisure activities. RESULTS: The participants provided detailed, contextual information about their injuries, including the contributing factors and the experience of living with a WRMI. The findings indicate that injured osteopaths often continue working because of financial commitments and their dedication to patient care. The participants offered insights into the challenges they faced due to the injury and the management strategies they used to deal with the impact on their work and personal life. The injuries were mostly unreported, the burden being carried by the participants and their families. CONCLUSION: This is the first research that explores the experiences of osteopaths who have sustained a WRMI. We anticipate that this research will encourage a broad and constructive discussion within the profession of the issues associated with WRMIs, including risk minimisation and injury prevention. Further research is warranted to understand the relationship between osteopaths training in ergonomics and injury prevention. This would lead to the development of guidelines and educational curricula addressing safe work for osteopaths.

Associations between community-based physiotherapy for musculoskeletal injury and health related quality of life (EQ-5D): a multi-centre retrospective analysis.

BACKGROUND: Community-based musculoskeletal physiotherapy is used to improve function and health related quality of life (HRQoL). The purpose of this retrospective, multi-centre observational study was to determine the association between community-based physiotherapy management for musculoskeletal disorders and changes in HRQoL. METHODS: Four thousand one hundred twelve patients' data were included in the study. Patients were included if they received a single period of treatment for a musculoskeletal injury or disorder. Patients were only included if they were being treated for a single morbidity. Patients received standard physiotherapy appropriate to their specific disorder, which could include health education/advice, exercise therapy, manual therapy, taping, soft tissue techniques, electrotherapy and/or acupuncture. Health related quality of life was assessed using the EQ-5D index. RESULTS: EQ-5D improved by 0.203 across all patients (d = 1.10). When grouped by anatomical site of symptom, the largest increases in EQ-5D was in foot pain (0.233; d = 1.29) and lumbar pain (0.231; d = 1.13). Improvements in EQ-5D greater than the minimum clinically important difference (MCID) were seen in 68.4% of all patients. The highest proportion of patients with positive responses to treatment were in ankle pain (74.2%) and thoracic pain (73.4%). The hand (40.5%), elbow (34.7%), and hip (33.9%) showed the greatest proportion of patients that did not respond to treatment. CONCLUSIONS: Community-based musculoskeletal physiotherapy is associated with improved health related quality of life. A randomised controlled trial is needed to determine any causal relationship between community-based physiotherapy and health related quality of life improvements.
