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.

Musculoskeletal anatomy knowledge in Australian chiropractors.

Anatomy is a key knowledge area in chiropractic and is formally offered in the undergraduate component of chiropractic education. There is the potential for loss of anatomy knowledge before the opportunity to apply it in a clinical setting. This study aimed to determine whether chiropractic clinicians retain a level of anatomy knowledge comparable to that of chiropractic students and to compare chiropractors' self-rating of their anatomical knowledge against an objective knowledge assessment tool. A previously validated multiple-choice test was utilized to measure retention of limb musculoskeletal (MSK) knowledge in Australian chiropractors. One hundred and one registered chiropractors completed the questionnaire and responses were scored, analyzed, and compared to scores attained by undergraduate and postgraduate chiropractic students who had previously completed the same questionnaire. The results indicated that practitioners retained their anatomy knowledge, with a significantly higher total mean score than the undergraduate group [total mean score = 36.5% (±SD 13.6%); P < 0.01] but not significantly different to the postgraduate group [total mean score = 52.2% (±SD 14.1%); P = 0.74]. There was a weak positive correlation between chiropractors' self-rated knowledge and test performance scores indicating the effectiveness of this Australian chiropractic group in self-assessing their anatomy knowledge. This study found that Australian chiropractors' knowledge of MSK anatomy was retained during the transition from university to clinical practice and they accurately evaluated their own test performance.

The effects of body position and actual execution on motor imagery of locomotor tasks in people with a lower-limb amputation.

Motor imagery (MI) is usually facilitated when performed in a congruent body position to the imagined movement, as well as after actual execution (AE). A lower-limb amputation (LLA) results in important structural and functional changes in the sensorimotor system, which can alter MI. In this study, we investigated the effects of body position and AE on the temporal characteristics of MI in people with LLA. Ten participants with LLA (mean age = 59.6 ± 13.9 years, four females) and ten gender- and age-matched healthy control participants (mean age = 60.1 ± 15.4 years, four females) were included. They performed two locomotor-related tasks (a walking task and the Timed Up and Go task) while MI times were measured in different conditions (in congruent/incongruent positions and before/after AE). We showed that MI times were significantly shorter when participants imagined walking in a congruent-standing position compared to an incongruent-sitting position, and when performing MI after actual walking compared to before, in both groups. Shorter MI times in the congruent position and after AE suggest an improvement of MI's temporal accuracy (i.e. the ability to match AE time during MI) in healthy individuals but not in the LLA group.

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.

Non-Musculoskeletal Benefits of Vitamin D beyond the Musculoskeletal System.

Vitamin D, a fat-soluble prohormone, is endogenously synthesized in response to sunlight or taken from dietary supplements. Since vitamin D receptors are present in most tissues and cells in the body, the mounting understanding of the role of vitamin D in humans indicates that it does not only play an important role in the musculoskeletal system, but has beneficial effects elsewhere as well. This review summarizes the metabolism of vitamin D, the research regarding the possible risk factors leading to vitamin D deficiency, and the relationships between vitamin D deficiency and numerous illnesses, including rickets, osteoporosis and osteomalacia, muscle weakness and falls, autoimmune disorders, infectious diseases, cardiovascular diseases (CVDs), cancers, and neurological disorders. The system-wide effects of vitamin D and the mechanisms of the diseases are also discussed. Although accumulating evidence supports associations of vitamin D deficiency with physical and mental disorders and beneficial effects of vitamin D with health maintenance and disease prevention, there continue to be controversies over the beneficial effects of vitamin D. Thus, more well-designed and statistically powered trials are required to enable the assessment of vitamin D's role in optimizing health and preventing disease.

The study on the clinical effectiveness and safety of traditional Chinese medicine acupoint catgut embedding guided by musculoskeletal ultrasound in the treatment of nerve root sciatica: A protocol for systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Nerve root sciatica (NRS) is a common orthopedic disease, which usually occurs between 20 and 40 years of age, and the incidence rate is increasing year by year and is being younger. The disease has no special effect of treatment, clinically generally taking the symptomatic treatment, such as taking short-term glucocorticoids, sedatives, analgesics, and so on. Long-term use of drugs will adversely affect the patient's gastrointestinal tract, liver, and kidney function. The surgical treatment has a high risk of surgery, high cost, side effects, and other problems, so the choice of treatment method has always been a difficult problem in clinical and scientific research. The study shows that 90% of patients with sciatica can be cured by non-surgical treatment, so conservative therapy is often used in the treatment of sciatica, traditional Chinese medicine treatment methods in the treatment of NRS has been widely used, which has achieved good results, but there is no evidence of evidence-based medicine. Therefore, this study uses systematic evaluation to conduct the scientific evaluation of the clinical effectiveness and safety of traditional Chinese medicine acupoint catgut embedding guided by musculoskeletal ultrasound in the treatment of NRS, and provide evidence-based medical evidence support for the treatment of NRS. METHODS: Using the computer to retrieve the PubMed, ScienceDirect, Web of Science, Embase, Cochrane Library, CNKI, VIP, WANFANG Database, and CBM. Using the subject words and terminology words to retrieve the Chinese-English database and retrieve a randomized controlled study on the clinical effectiveness and safety of traditional Chinese medicine acupoint catgut embedding guided by musculoskeletal ultrasound in the treatment of NRS, and the range of search time is January 1990 to January 2021. The searched literature is screened and evaluated by two researchers respectively according to the inclusion and exclusion criteria. If there is disagreement, discussing it with the third researcher to determine the final inclusion of the literature. Using the RevMan 5.3 software to conduct the meta-analysis. RESULTS: This study will compare the effectiveness and safety of traditional Chinese medicine acupoint catgut embedding guided by musculoskeletal ultrasound in the treatment of NRS. CONCLUSION: The results of this study will be published in internationally influential academic journals to provide evidence-based medical evidence for the clinical effectiveness and safety of traditional Chinese medicine acupoint catgut embedding in the treatment of NRS. ETHICS AND DISSEMINATION: This study does not involve specific patients, and all research data comes from publicly available professional literature, so an ethics committee is not required to conduct an ethical review and approval of the study.

El guaco: un agente vegetal utilizado en el Nuevo Reino de Granada contra los síntomas generados por afecciones del sistema músculo-esquelético / Guaco: A plant agent used in the New Kingdom of Granada against symptoms generated by disorders of the musculoskeletal system

RESUMEN Objetivo: Contextualizar una receta médica de comienzos del siglo XIX en el Nuevo Reino de Granada, en la cual se prescribe el guaco para disminuir síntomas generados por afecciones del sistema músculo-esquelético. De igual forma, analizar, en función de los conocimientos actuales, cómo actúa la fórmula sobre mecanismos fisiopatológicos de la enfermedad, explicando la reducción del dolor y las secuelas asociadas. Material y método: Búsqueda documental en el Archivo Histórico Cipriano Rodríguez Santamaría, de la Biblioteca Octavio Arizmendi Posada, de la Universidad de La Sabana. Se analizó el documento denominado Reumatismo. Posteriormente se realizó una revisión de la literatura entre 1999-2018, en las bases de datos ScienceDirect/ClinicalKey/Scielo. Conclusiones: Existe evidencia científica que podría explicar la efectividad del guaco, usado en el Nuevo Reino de Granada por sus propiedades antiinflamatorias y analgésicas aportadas por componentes como la cumarina y los flavonoides. Sin embargo, una descripción vaga en la posología del guaco, signos, síntomas y comorbilidades que no se mencionan en la receta, dificulta analizar la eficacia del tratamiento y cómo lograba disminuir o controlar específicamente los síntomas dados por afecciones del sistema musculoesquelético con su aplicación. Esta tradición, en consecuencia, carece de sustento propiamente científico para el tratamiento médico de enfermedades osteomusculares.

ABSTRACT Objective: To contextualize a medical prescription of the early 19th century in the New Kingdom of Granada, in which guaco was prescribed to reduce symptoms caused by musculoskeletal system disorders, which were ill-defined at the time. Similarly, based on current knowledge, to analyse the manner in which the formula acts on pathophysiological mechanisms of rheumatic diseases, in order to explain the reduction of pain, and associated sequelae. Material and method: Documentary research into the Cipriano Rodríguez Santamaría Historical Archive of the Octavio Arizmendi Library of the University of La Sabana, in Chía, Colombia. The document analysed was called Rheumatism. Subsequently, a review of the literature was carried out in Science Direct / Clinical Key / Scielo databases in the period from 1999 to 2018. Conclusions: There is scientific evidence that supports the efficiency of guaco used in the Kingdom of New Granada due its anti-inflammatory and analgesic properties. However, a vague description of the dosage of the guaco, signs, symptoms, and comorbidities, which are not mentioned in the prescription, hinders the understanding of its application and the thorough effectiveness of the treatment in order to control the symptoms of musculoskeletal system conditions. This tradition, consequently, lacks proper scientific support for the medical treatment of musculoskeletal disorders.

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.

Impact of musculoskeletal degradation on cancer outcomes and strategies for management in clinical practice.

The prevalence of malnutrition in patients with cancer is one of the highest of all patient groups. Weight loss (WL) is a frequent manifestation of malnutrition in cancer and several large-scale studies have reported that involuntary WL affects 50-80% of patients with cancer, with the degree of WL dependent on tumour site, type and stage of disease. The study of body composition in oncology using computed tomography has unearthed the importance of both low muscle mass (sarcopenia) and low muscle attenuation as important prognostic indications of unfavourable outcomes including poorer tolerance to chemotherapy; significant deterioration in performance status and quality of life (QoL), poorer post-operative outcomes and shortened survival. While often hidden by excess fat and high BMI, muscle abnormalities are highly prevalent in patients with cancer (ranging from 10 to 90%). Early screening to identify individuals with sarcopenia and decreased muscle quality would allow for earlier multimodal interventions to attenuate adverse body compositional changes. Multimodal therapies (combining nutritional counselling, exercise and anti-inflammatory drugs) are currently the focus of randomised trials to examine if this approach can provide a sufficient stimulus to prevent or slow the cascade of tissue wasting and if this then impacts on outcomes in a positive manner. This review will focus on the aetiology of musculoskeletal degradation in cancer; the impact of sarcopenia on chemotherapy tolerance, post-operative complications, QoL and survival; and outline current strategies for attenuation of muscle loss in clinical practice.

Tissue selective effects of bazedoxifene on the musculoskeletal system in female mice.

The actions of selective estrogen receptor modulators are tissue dependent. The primary objective of the current study was to determine the tissue selective effects of bazedoxifene (BZA) on the musculoskeletal system of ovariectomized (OVX) female mice, focusing on the strengths of muscle-bone pairs in the lower hindlimb. Treatment with BZA after ovariectomy (OVX+BZA) did not prevent body or fat mass gains (P < 0.05). In vivo plantarflexor muscle isometric torque was not affected by treatment with BZA (P = 0.522). Soleus muscle peak isometric, concentric and eccentric tetanic force production were greater in OVX+BZA mice compared to OVX+E2 mice (P ≤ 0.048) with no effect on maximal isometric specific force (P = 0.228). Tibia from OVX+BZA mice had greater cortical cross-sectional area and moment of inertia than OVX mice treated with placebo (P < 0.001), but there was no impact of BZA treatment on cortical bone mineral density, cortical thickness, tibial bone ultimate load or stiffness (P ≥ 0.086). Overall, these results indicate that BZA may be an estrogen receptor agonist in skeletal muscle, as it has previously been shown in bone, providing minor benefits to the musculoskeletal system.

The emerging role of miR-128 in musculoskeletal diseases.

MicroRNA-128 (miR-128) is associated with cell proliferation, differentiation, migration, apoptosis, and survival. Genetic analysis studies have demonstrated that miR-128 participates in bone metabolism, which involves bone marrow-derived mesenchymal stem cells, osteoblasts, osteoclasts, and adipocytes. miR-128 also participates in regeneration of skeletal muscles by targeting myoblast-associated proteins. The deregulation of miR-128 could lead to a series of musculoskeletal diseases. In this review, we discuss recent findings of miR-128 in relation to bone metabolism and muscle regeneration to determine its potential therapeutic effects in musculoskeletal diseases, and to propose directions for future research in this significant field.

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).

Cholecalciferol or Calcifediol in the Management of Vitamin D Deficiency.

Vitamin D deficiency is a global health problem due to its high prevalence and its negative consequences on musculoskeletal and extra-skeletal health. In our comparative review of the two exogenous vitamin D supplementation options most used in our care setting, we found that cholecalciferol has more scientific evidence with positive results than calcifediol in musculoskeletal diseases and that it is the form of vitamin D of choice in the most accepted and internationally recognized clinical guidelines on the management of osteoporosis. Cholecalciferol, unlike calcifediol, guarantees an exact dosage in IU (International Units) of vitamin D and has pharmacokinetic properties that allow either daily or even weekly, fortnightly, or monthly administration in its equivalent doses, which can facilitate adherence to treatment. Regardless of the pattern of administration, cholecalciferol may be more likely to achieve serum levels of 25(OH)D (25-hydroxy-vitamin D) of 30-50 ng/mL, an interval considered optimal for maximum benefit at the lowest risk. In summary, the form of vitamin D of choice for exogenous supplementation should be cholecalciferol, with calcifediol reserved for patients with liver failure or severe intestinal malabsorption syndromes.

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.

EURO-MUSCULUS/USPRM Global Report on Musculoskeletal Ultrasound Publications.

The developments in technology have improved access to the use of musculoskeletal ultrasound (MSUS) in different clinical settings. Accordingly, MSUS has been applied to a wide range of musculoskeletal problems including inflammatory and degenerative diseases, sport injuries, and regional pain syndromes both for clinical practice and research. In this report, the authors aimed to globally examine the publications on MSUS among different specialties, countries, and topics. Sixteen reviewers under the umbrella of the European Musculoskeletal Ultrasonography Society Group and the Ultrasound Study Group of International Society of Physical and Rehabilitation Medicine have evaluated approximately 15,000 publications on MSUS. The authors believe that the results of this comparative analysis may provide a holistic snapshot with regard to the utility of MSUS, not only for clinicians/academicians but also for the industry. Accordingly, while aiming to further increase their awareness, this article would possibly guide future investments as well.

Influence of combined vitamin D3 supplementation and resistance exercise training on musculoskeletal health in older men and women (EXVITD): protocol for a randomised controlled trial.

INTRODUCTION: Sarcopenia is a progressive loss in muscle mass, strength and function, the adverse consequences of which are severe, affecting quality of life and placing an increasing burden on social and healthcare systems. Vitamin D status is known to be associated with markers of sarcopenia, namely muscle mass, strength and function. Also, resistance exercise training (RET) is currently the only proven intervention to treat sarcopenia. However, very little data exist on the influence of combining the two interventions of vitamin D supplementation and resistance exercise training, although a recent systematic review provides tentative support for the current study's hypothesis that the combined intervention may further improve musculoskeletal function above exercise training alone. The aim of the present study is to determine whether vitamin D3 supplementation is any more effective in improving musculoskeletal function when combined with RET compared with exercise training alone in older adults. METHODS AND ANALYSIS: This double-blinded randomised placebo-controlled trial will recruit a target of 127 eligible men and women aged ≥65 years living independently or in sheltered housing within the Birmingham area to two groups: (1) 6 months RET and placebo or (2) 6 months RET and 800 IU/d vitamin D3. Measures of muscle power (Nottingham Power Rig), body composition (dual energy X-ray absorptiometry), muscle function (short physical performance battery, timed up and go), falls and fractures as events will be assessed. Assessments will take place at baseline and postintervention, with intermittent monitoring of bone turnover, calcium and vitamin D. The primary outcome will be lower limb extensor power output. Analyses of within-group changes and between-group differences in outcome measures are planned. ETHICS AND DISSEMINATION: The EXVITD study has ethical approval granted by the Black Country National Health Service Research Ethics Committee (14/WM/1220). Results of this trial will be submitted for publication in peer-reviewed journals and presented at conferences. The study is being conducted according to the principles of the Declaration of Helsinki.Trial registration numberNCT02467153; Post-results.

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.
