RESUMO
BACKGROUND: Despite the well-known benefits of physical activity, physical inactivity is presently a global health pandemic. Allied healthcare providers, such as chiropractors, knowingly recognise the importance of physical activity and are prepared to routinely discuss and/or counsel patients on this topic; however, little is known about Australian chiropractors in the physical activity setting. Our aim was to explore and identify factors associated with physical activity promotion among Australian chiropractors, including their knowledge of the physical activity and sedentary behaviour guidelines and their own levels of physical activity. METHODS: From February to May 2021, a convenience sample of Australian chiropractors completed an online survey. Items assessed by Likert scale included: physical activity promotion frequency, with the type, quantity, barriers, perceptions, and feasibility. We asked questions about their familiarity with, and knowledge of, Australian Physical Activity and Sedentary Behaviour Guidelines, chiropractors' own physical activity, and whether the chiropractors met activity guidelines. Survey responses were descriptively reported. Univariable logistic regression models explored factors explaining frequent physical activity promotion. RESULTS: Of 217 respondents, 64% reported that they frequently (≥ 70%) recommended a more physically active lifestyle. Only 15% often performed pre-exercise screening, 73% frequently prescribed resistance exercise, 19% reported time as the most frequent barrier, while 37% reported being not at all familiar with the guidelines. Univariable logistic regression models found male chiropractors were more likely to promote physical activity, [odds ratio (OR) = 2.33; 95% confidence interval (CI): 1.32-4.12)], while chiropractors who frequently treat children 0-3 years (OR = 0.5; 95% CI: 0.28-0.87), children 4-18 years (OR = 0.42; 95% CI: 0.21-0.86), and pregnant women (OR = 0.5; 95% CI: 0.26-0.94) were less likely. Chiropractors were more likely to promote physical activity if they were familiar with the activity guidelines (OR = 2.9; 95% CI: 1.32-6.41), were confident promoting (OR = 11.6; 95% CI: 1.37-98.71) and prescribing physical activity programs (OR = 4.5; 95% CI: 2.03-9.99). CONCLUSION: Most chiropractors confidently and regularly integrate physical activity into practice. Yet, despite acknowledging its importance, one third of chiropractors reported poor knowledge of the Physical Activity and Sedentary Behaviour Guidelines. Identifying barriers to the awareness, and implementation of physical activity guidelines should be further explored within chiropractic clinical settings.

Atezolizumab (anti-PD-L1), combined with carboplatin and etoposide (CE), is now a standard of care for extensive-stage small-cell lung cancer (ES-SCLC). A clearer understanding of therapeutically relevant SCLC subsets could identify rational combination strategies and improve outcomes. We conduct transcriptomic analyses and non-negative matrix factorization on 271 pre-treatment patient tumor samples from IMpower133 and identify four subsets with general concordance to previously reported SCLC subtypes (SCLC-A, -N, -P, and -I). Deeper investigation into the immune heterogeneity uncovers two subsets with differing neuroendocrine (NE) versus non-neuroendocrine (non-NE) phenotypes, demonstrating immune cell infiltration hallmarks. The NE tumors with low tumor-associated macrophage (TAM) but high T-effector signals demonstrate longer overall survival with PD-L1 blockade and CE versus CE alone than non-NE tumors with high TAM and high T-effector signal. Our study offers a clinically relevant approach to discriminate SCLC patients likely benefitting most from immunotherapies and highlights the complex mechanisms underlying immunotherapy responses.

BACKGROUND: Physical inactivity is a global health pandemic. Allied healthcare providers, including chiropractors, are well placed to integrate individual physical activity (PA) promotion into routine care. A previous systematic review identified that approximately 90% of chiropractors held a positive opinion towards healthier patient lifestyles; however, the extent to which chiropractors promote PA to their patients within routine care is unclear. This systematic review aimed to describe chiropractors' attitudes towards and current practice in advising, counselling, discussing, supporting, or recommending PA to patients. METHODS: Five databases were searched from inception to December 2021 for cross-sectional surveys that explored PA promotion by chiropractors in practice. We assessed the risk of bias of the included studies with the 'Risk of Bias in Cross-Sectional Surveys of Attitudes and Practices' tool. Descriptive data were extracted, grouping similar survey questions and responses into emerging categories. Chiropractors' views regarding the perceived importance and/or their preparedness to counsel and provide PA or exercise information are reported. RESULTS: From 661 studies, 15 met the selection criteria. Surveys included 7999 chiropractors primarily from the USA, UK, Australia, and Sweden. All studies were rated as moderate-to-high risk of bias, with methodological weaknesses characterised by inconsistent reporting of missing data, non-representative samples, low response rates (i.e., less than 60%), and unknown validity of survey instruments. Chiropractors frequently recognised the importance of PA promotion, as demonstrated by the proportion of respondents reporting that they: (1) support the importance of providing PA or exercise information and counselling (64% to 100%); (2) are prepared to provide PA or exercise information and/or counselling to patients (91% to 92%,); (3) frequently obtain PA or exercise information from patients (87% to 97%,); 4) frequently discuss PA or exercise and/or provide PA or exercise information to patients (68% to 99%); and 5) frequently provide PA counselling to patients (50% to 81%.). CONCLUSION: A large majority of practising chiropractors actively engage with PA promotion. However, the results should be interpreted with caution owing to the moderate-to-high risk of bias of the included studies. Forthcoming research initiatives should explore unbiased surveys, further PA education and training as well as capitalising on chiropractors' own PA participation.

BACKGROUND: Practice-based guidelines recommend patient education and exercise as first-line care for low back pain (LBP); however, these recommendations are not routinely delivered in practice. GLA:D® Back, developed in Denmark to assist clinicians to implement guideline recommendations, offers a structured education and supervised exercise program for people with LBP in addition to a clinical registry to evaluate patient outcomes. In this study we evaluated the feasibility of implementing the GLA:D® Back program in Australia. We considered clinician and patient recruitment and retention, program fidelity, exploring clinicians' and patients' experiences with the program, and participant outcome data collection. METHODS: Clinicians (chiropractors and physiotherapists) were recruited and participated in a 2-day GLA:D® Back training course. Patients were eligible to participate if they had persistent or recurrent LBP. Feasibility domains included the ability to: (1) recruit clinicians to undergo training; (2) recruit and retain patients in the program; (3) observe program fidelity; and (4) perceive barriers and facilitators for GLA:D® Back implementation. We also collected data related to: (5) clinician confidence, attitudes, and behaviour; and (6) patient self-reported outcomes related to pain, disability, and performance tests. RESULTS: Twenty clinicians (8 chiropractors, 12 physiotherapists) participated in the training, with 55% (11/20) offering GLA:D® Back to their patients. Fifty-seven patients were enrolled in the program, with 67% (38/57) attending the final follow-up assessment. Loss to follow up was mainly due to the effects of the COVID-19 pandemic. We observed program fidelity, with clinicians generally delivering the program as intended. Interviews revealed two clinician themes related to: (i) intervention acceptability; and (ii) barriers and facilitators to implementation. Patient interviews revealed themes related to: (i) intervention acceptability; and (ii) program efficacy. At 3 months follow-up, clinicians demonstrated high treatment confidence and biomedical orientation. Patient outcomes trended towards improvement. CONCLUSION: GLA:D® Back implementation in Australia appears feasible based on clinician recruitment, program acceptability and potential benefits for patient outcomes from the small sample of participating clinicians and patients. However, COVID-19 impacted patient recruitment, retention, and data collection. To scale-up GLA:D® Back in private and public settings, further work is warranted to address associated barriers, and to leverage facilitators.

BACKGROUND: A variety of treatments aim to reduce thoracic hyperkyphosis in adults, thereby improving posture and reducing possible complications. OBJECTIVE: To investigate the effectiveness of treatments to reduce thoracic hyperkyphosis. DESIGN: Systematic review and meta-analysis. METHODS: MEDLINE, EMBASE, CINAHL, and CENTRAL were searched from inception to March 2021. Two authors independently selected randomised controlled trials assessing the effectiveness of treatments to reduce thoracic hyperkyphosis in adults. Raw data on mean change in thoracic kyphosis were extracted and standardised mean differences (SMD) calculated. Meta-analysis was performed on studies homogenous for study population and intervention. Strength of evidence was assessed using GRADE. RESULTS: Twenty-eight studies were included, with five meta-analyses performed. Low to moderate-quality evidence found structured exercise programs of three-months duration or less effective in reducing thoracic hyperkyphosis in younger (SMD -2.8; 95%CI -4.3 to -1.3) and older populations (SMD -0.3; 95%CI -0.6 to 0.0). Low-quality evidence found bracing for three months or more effective in older participants (SMD -1.0, 95%CI -1.3 to -0.7). A single study demonstrated the effectiveness of multimodal care in younger participants. The available evidence suggests multimodal care, structured exercise programs over three months duration, and taping in older adults, and biofeedback and muscle stimulation in younger adults, are ineffective in reducing thoracic hyperkyphosis. CONCLUSION: Low to moderate-quality evidence indicates that structured exercise programs are effective to reduce thoracic hyperkyphosis. Low-quality evidence indicates that bracing is effective to reduce thoracic hyperkphosis in older adults.

OBJECTIVE: To explore the self-perceived preparedness and clinical proficiency in headache diagnosis and management of Australian chiropractic students in senior years of study. METHODS: Australian chiropractic students in the 4th (n = 134) and 5th year (n = 122) of 2 chiropractic university programs were invited to participate in an online cross-sectional survey. Descriptive analyses were conducted for all variables. Post hoc analyses were performed using simple linear regression to evaluate the relationship between self-perceived preparedness and correctness of headache diagnosis and management scores. RESULTS: Australian chiropractic students in senior years demonstrated moderate overall levels of self-perceived preparedness and proficiency in their ability to diagnose and manage headache disorders. Final-year students had a slightly higher self-perceived preparedness and proficiency in headache diagnosis and management compared to those students in the 4th year of study. There was no relationship between self-perceived preparedness and correctness of headache diagnosis and management for either 4th- or 5th-year chiropractic students. CONCLUSION: Our findings suggest that there may be gaps in graduate chiropractic student confidence and proficiency in headache diagnosis and management. These findings call for further research to explore graduate chiropractic student preparedness and proficiency in the diagnosis and management of headache disorders.
RESUMO
The Chiropractic Academy for Research Leadership (CARL) was formed in 2016 in response to a need for a global network of early career researchers and leaders in the chiropractic profession. Thirteen fellows were accepted competitively and have since worked together at residentials and virtually on many research and leadership projects. In 2020, the CARL program ended for this first cohort, and it is now timely to take stock and reflect on the achievements and benefits of the program. In this paper we present the structure of CARL, the scientific and leadership outputs as well as the personal value of CARL for the participating fellows. As a result of the success of the first CARL cohort, organizations from Europe, North America, and Australia have supported a second cohort of 14 CARL fellows, who were competitively accepted into the program in early 2020.

BACKGROUND: Spinal manipulative therapy (SMT) is frequently used to manage cervicogenic headache (CGHA). No meta-analysis has investigated the effectiveness of SMT exclusively for CGHA. OBJECTIVE: To evaluate the effectiveness of SMT for CGHA. DATABASES AND DATA TREATMENT: Five databases identified randomized controlled trials comparing SMT with other manual therapies. The PEDro scale assessed the risk-of-bias. Pain and disability data were extracted and converted to a common scale. A random effects model was used for several follow-up periods. GRADE described the quality of evidence. RESULTS: Seven trials were eligible. At short-term follow-up, there was a significant, small effect favouring SMT for pain intensity (mean difference [MD] -10.88 [95% CI, -17.94, -3.82]) and small effects for pain frequency (standardized mean difference [SMD] -0.35 [95% CI, -0.66, -0.04]). There was no effect for pain duration (SMD - 0.08 [95% CI, -0.47, 0.32]). There was a significant, small effect favouring SMT for disability (MD - 13.31 [95% CI, -18.07, -8.56]). At intermediate follow-up, there was no significant effects for pain intensity (MD - 9.77 [-24.21 to 4.68]) and a significant, small effect favouring SMT for pain frequency (SMD - 0.32 [-0.63 to - 0.00]). At long-term follow-up, there was no significant effects for pain intensity (MD - 0.76 [-5.89 to 4.37]) and for pain frequency (SMD - 0.37 [-0.84 to 0.10]). CONCLUSION: For CGHA, SMT provides small, superior short-term benefits for pain intensity, frequency and disability, but not pain duration, however, high-quality evidence in this field is lacking. The long-term impact is not significant. SIGNIFICANCE: CGHA are a common headache disorder. SMT can be considered an effective treatment modality, with this review suggesting it providing superior, small, short-term effects for pain intensity, frequency and disability when compared with other manual therapies. These findings may help clinicians in practice better understand the treatment effects of SMT alone for CGHA.

BACKGROUND: Approximately one in four adults do not meet the World Health Organisation physical activity recommendations. While health promotion (i.e., physical activity) is common within chiropractic settings, little is known about chiropractors discussing this public health issue with their patients. The aim of our study is to examine the prevalence and characteristics of Australian chiropractors who frequently discuss patient physical activity. METHODS: A national cross-sectional survey of chiropractors focusing upon practitioner characteristics, practice settings and clinical management characteristics. Regression analyses were conducted on 1924 survey respondents to identify factors associated with practitioners who frequently discuss physical activity with patients. RESULTS: Eighty-five percent of Australian chiropractors reported 'often' discussing physical activity as part of their patient management. The strongest factors associated with chiropractors who frequently discuss physical activity obtained from the multivariate analysis include: often discussing occupational health and safety (odds ratio [OR]â¯=â¯6.10; 95%CI: 3.88, 9.59), often discussing diet/nutrition (ORâ¯=â¯4.56; 95%CI: 3.12, 6.66), often discussing smoking/drugs/alcohol (ORâ¯=â¯4.41; 95%CI: 2.06, 9.40), often use of specific exercise therapy/rehabilitation/injury taping (ORâ¯=â¯3.76; 95%CI: 2.62, 5.39) and often caring for athletes or sports people (ORâ¯=â¯2.18; 95%CI: 1.56, 3.06) within their practice setting. CONCLUSION: Discussing physical activity is a frequent feature of patient management among most chiropractors in Australia. The association between these practitioners and discussion of other costly public health burdens could suggest chiropractors have a valuable role to play in chronic disease prevention. Given the growing need for practitioner-led promotion of patient physical activity further research examination of the role and contribution of chiropractors in promoting this important public health topic among patients and communities is needed.

OBJECTIVE: To examine the prevalence and profile of chiropractors who frequently manage people aged 65 years and older. METHODS: A national cross-sectional survey collected practitioner characteristics, practice settings and clinical management characteristics. Multiple logistic regression was conducted on 1903 chiropractors to determine the factors associated with the frequent treatment of people 65 years and older. RESULTS: In total, 73.5% of participants report "often" treating those aged 65 years and older. These chiropractors were associated with treating degenerative spine conditions (OR [odds ratio] 2.25; 95% [confidence interval] CI 1.72-2.94), working in a non-urban area (OR 1.85; 95% CI 1.35-2.54), treating low back pain (referred/radicular) (OR 1.74; 95% CI 1.26-2.40) and lower limb musculoskeletal disorders (OR 1.50; 95% CI 1.15-1.96). CONCLUSIONS: The majority of chiropractors report often providing treatment to older people. Our findings call for more research to better understand older patient complaints that are common to chiropractic practice and the care provided by chiropractors for this patient group.

Background: Approximately 60% of people with low back pain also have associated leg pain symptoms. Guidelines for low back pain recommend non-pharmacological approaches, including spinal manipulation - a therapy provided by chiropractors. However, limited empirical data has examined the characteristics of chiropractors managing patients with low back-related leg pain (LBRLP). Our objective is to describe the prevalence, profile and practice characteristics of Australian chiropractors who often treat LBRLP, compared to those who do not often treat LBRLP. Methods: This is a cross-sectional analysis of a nationally representative sample from the Australian Chiropractic Research Network (ACORN). This study investigated the demographic and practice characteristics as well as clinical management of chiropractors who 'often' treated patients with LBRLP compared to those who treated LBRLP 'never/rarely/sometimes'. Multiple logistic regression models identified independent factors associated with chiropractors who 'often' treated patients with LBRLP. Results: A total of 1907 chiropractors reported treating patients experiencing LBRLP, with 80.9% of them 'often' treating LBRLP. Chiropractors who 'often' treated LBRLP were more likely to manage patients with multi-site pain including axial low back pain (OR = 21.1), referred/radicular neck pain (OR = 10.8) and referred/radicular thoracic pain (OR = 3.1). While no specific management strategies were identified, chiropractors who 'often' treated LBRLP were more likely to discuss medication (OR = 1.8), manage migraine (OR = 1.7) and degenerative spine conditions (OR = 1.5), and treat women during pregnancy (OR = 1.6) and people with work-related injuries (OR = 1.5), compared to those not treating LBRLP frequently. Conclusions: Australian chiropractors frequently manage LBRLP, although the nature of specific management approaches for this condition remains unclear. Further research on the management of LBRLP can better inform policy makers and educators interested in upskilling chiropractors to deliver safe and effective treatment of LBRLP.

Background: Musculoskeletal pain frequently occurs in more than one body region, with up to 80% of adults reporting more than one joint pain site in the last 12 months. Older people and females are known to be more susceptible to multiple joint pain sites, however the association of multisite joint pain with physical and psychosocial functions in this population are unknown. Methods: Cross-sectional data from 579 women were analyzed. Women were asked "Which of your joints have been troublesome on most days of the past month?" Pain qualities were measured using the McGill Pain Questionnaire (Short Form) and PainDETECT, and health was assessed using the SF-36 and sociodemographic variables. Statistical analysis using generalized ordinal logistic regression included comparison of three joint pain groups: no joint pain, 1-4 sites of joint pain and ≥ 5 sites of joint pain. Results: Two thirds of respondents had multisite pain (>1 site), and one third had ≥5 joint pain sites. Compared to women with fewer joint pain sites, women with >5 joint pain sites (multisite joint pain) had significantly poorer physical and emotional health-related quality of life, more severe pain, a higher probability of neuropathic pain, and a longer duration of pain. More than half of women in the multisite joint pain group were still employed, statistically significantly more than women with no joint pain. In the final model, pain duration, the number of medications, pain intensity (discomforting and distressing) and the physical component of health-related quality of life were significantly associated with increased number of joint pain sites. Conclusions: Over one-third of older women in our sample had >5 painful joints in the last month. These women demonstrated significantly poorer psychosocial health, and increased medication use, than women with no or fewer sites of joint pain. Many women with multisite joint pain were still in the workforce, even when nearing retirement age. This study has important implications for future research into musculoskeletal pain, particularly in regards to womens health and wellbeing, and for clinical practice where there should be increased awareness of the implications of concurrent, multisite joint pain.

OBJECTIVE:: To evaluate Australian and New Zealand chiropractic students' opinions regarding the identity, role setting, and future of chiropractic practice. METHODS:: An online, cross-sectional survey was administered to chiropractic students in all chiropractic programs in Australia and New Zealand. The survey explored student viewpoints about the identity, role/scope, setting, and future of chiropractic practice as it relates to chiropractic education and health promotion. Associations between the number of years in the program, highest degree preceding chiropractic education, institution, and opinion summary scores were evaluated by multivariate analysis of variance tests. RESULTS:: A total of 347 chiropractic students participated in the study. For identity, most students (51.3%) hold strongly to the traditional chiropractic theory but also agree (94.5%) it is important that chiropractors are educated in evidence-based practice. The main predictor of student viewpoints was a student's chiropractic institution (Pillai's trace =.638, F[16, 1368] = 16.237, p < .001). Chiropractic institution explained over 50% of the variance around student opinions about role/scope of practice and approximately 25% for identity and future practice. CONCLUSIONS:: Chiropractic students in Australia and New Zealand seem to hold both traditional and mainstream viewpoints toward chiropractic practice. However, students from different chiropractic institutions have divergent opinions about the identity, role, setting, and future of chiropractic practice, which is most strongly predicted by the institution. Chiropractic education may be a potential determinant of chiropractic professional identity, raising concerns about heterogeneity between chiropractic schools.
RESUMO
In an evidence-based health care environment, healthcare professions require a sustainable research culture to remain relevant. At present however, there is not a mature research culture across the chiropractic profession largely due to deficiencies in research capacity and leadership, which may be caused by a lack of chiropractic teaching programs in major universities. As a response to this challenge the Chiropractic Academy for Research Leadership, CARL, was created with the aim of develop a global network of successful early-career chiropractic researchers under the mentorship of three successful senior academics from Australia, Canada, and Denmark. The program centres upon an annual week-long program residential that rotates continental locations over the first three-year cycle and between residentials the CARL fellows work on self-initiated research and leadership initiatives. Through a competivite application process, the first cohort was selected and consists of 13 early career researchers from five professions in seven countries who represent diverse areas of interests of high relevance for chiropractic. The first residential was held in Odense, Denmark, with the second being planned in April 2018 in Edmonton, Canada, and the final residential to be held in Sydney, Australia in 2019.

PURPOSE: To investigate whether depression symptomatology is associated with low back pain (LBP) in twins aged 70+ and whether this effect depends on a person's physical activity (PA) status. METHODS: This prospective cohort and nested case-control study used a nationally representative sample of twins. Data on depression symptomatology (modified Cambridge Mental Disorders Examination) and self-reported PA were obtained from the Longitudinal Study of Aging Danish Twins using twins without LBP at baseline. Associations between depression symptomatology (highest quartile) at baseline and LBP two years later were investigated using logistic regression analyses adjusted for sex. To examine the moderating effect of PA, we tested its interaction with depression. Associations were analysed using the complete sample of 2446 twins and a matched case-control analysis of 97 twin pairs discordant for LBP at follow-up. Odds ratios (OR) with 95% confidence intervals (CI) were calculated. RESULTS: Using the whole sample, high depression scores were associated with an increased probability of LBP (OR 1.56, 95% CI 1.22-1.99, P ≤ 0.01). There was no statistically significant interaction of light PA and depression symptomatology (OR 0.78, 95% CI 0.46-1.35, P = 0.39) and strenuous PA and depression symptomatology (0.84, 95% CI 0.50-1.41, P = 0.51). The case-control analysis showed similar ORs, although statistically insignificant. CONCLUSIONS: High depression symptomatology predicted incident LBP. This effect is supposedly not attributable to genetic or shared environmental factors. Physical activity did not moderate the effect of depression symptomatology on LBP.

PURPOSE: Previous reviews have compared surgical to non-surgical management of sciatica, but have overlooked the specific comparison between surgery and physical activity-based interventions. METHODS: Systematic review using MEDLINE, CINAHL, Embase and PEDro databases was conducted. Randomised controlled trials comparing surgery to physical activity, where patients were experiencing the three most common causes of sciatica-disc herniation, spondylolisthesis and spinal stenosis. Two independent reviewers extracted pain and disability data (converted to a common 0-100 scale) and assessed methodological quality using the PEDro scale. The size of the effects was estimated for each outcome at three different time points, with a random effects model adopted and the GRADE approach used in summary conclusions. RESULTS: Twelve trials were included. In the short term, surgery provided better outcomes than physical activity for disc herniation: disability [WMD -9.00 (95 % CI -13.73, -4.27)], leg pain [WMD -16.01 (95 % CI -23.00, -9.02)] and back pain [WMD -12.44 (95 % CI -17.76, -7.09)]; for spondylolisthesis: disability [WMD -14.60 (95 % CI -17.12, -12.08)], leg pain [WMD -35.00 (95 % CI -39.66, -30.34)] and back pain [WMD -20.00 (95 % CI -24.66, -15.34)] and spinal stenosis: disability [WMD -11.39 (95 % CI -17.31, -5.46)], leg pain [WMD, -27.17 (95 % CI -35.87, -18.46)] and back pain [WMD -20.80 (95 % CI -25.15, -16.44)]. Long-term and greater than 2-year post-randomisation results favoured surgery for spondylolisthesis and stenosis, although the size of the effects reduced with time. For disc herniation, no significant effect was shown for leg and back pain comparing surgery to physical activity. CONCLUSION: There are indications that surgery is superior to physical activity-based interventions in reducing pain and disability for disc herniation at short-term follow-up only; but high-quality evidence in this field is lacking (GRADE). For spondylolisthesis and spinal stenosis, surgery is superior to physical activity up to greater than 2 years follow-up. Results should guide clinicians and patients when facing the difficult decision of having surgery or engaging in active care interventions. PROSPERO registration number : CRD42013005746.

OBJECTIVE: The purpose of this case report is to describe the evaluation and conservative management of an isolated posterior cruciate ligament (PCL) tear. CLINICAL FEATURES: A 32-year-old man with a traumatic right knee injury after tripping was initially diagnosed with medial patellar retinaculum tear at a multidisciplinary clinic. The patient received physiotherapy but reinjured the knee after returning to the sports field 3 weeks later. Subsequent clinical testing and magnetic resonance imaging confirmed a grade II isolated PCL tear. INTERVENTION AND OUTCOME: Following the PCL tear diagnosis, a multimodal treatment approach over the course of 8 weeks consisting of chiropractic lumbopelvic manipulation, physiotherapy, and an exercise program emphasizing eccentric muscle action was implemented. Lunges, 1-leg squats, and trunk stabilization exercises were extensively used. Three months postinjury, the patient successfully returned to sports activity with no further complications. CONCLUSION: The patient in this case report demonstrated successful return to preinjury functional status. This case highlights a multidisciplinary approach through the utilization of chiropractic, physiotherapy, and exercise therapies.
RESUMO
OBJECTIVE: The objective of this article is to present and discuss a case of deep vein thrombosis in a chiropractic clinic setting. CLINICAL FEATURES: A 33-year-old male patient presented for follow-up chiropractic care for a long-term low back complaint. A working diagnosis of facet joint syndrome was made. Despite improvement of low back symptoms, the patient experienced right-sided groin pain. The patient was referred to the hospital with a provisional diagnosis of deep vein thrombosis. INTERVENTIONS AND OUTCOMES: The patient consulted a physician, and within 2 hours of chiropractic consultation, his entire leg had become painful. Doppler ultrasound revealed extensive thrombosis. He was placed on heparin and was hospitalized for 8 days. On discharge, a full-length right leg stocking and moderate exercise were recommended. Consecutive checkups were scheduled with the clot almost resolved at 19 months postdiagnosis. CONCLUSION: This case report highlights the importance for the manipulative therapist to be aware of cardiovascular disease mechanisms and associated risk factors, so comanagement via referral to the appropriate specialist can occur.
