ABSTRACT

INTRODUCTION: The 6 min walk test (6MWT) is a widely used, safe and effective submaximal exercise test. The primary outcome is the distance walked, but additional physiological and patient-reported metrics can be recorded. It is used to assess function and is commonly used within UK Defence Rehabilitation. However, there are no published British military 6MWT data in a non-injured population. This study reports the 6MWT procedure and results from healthy British service personnel. METHODS: A convenience sample of 46 individuals (male n=40) undertook 95 6MWTs over three study visits throughout a year. They were performed on a 20 m straight-line route, administered by an exercise rehabilitation instructor and preceded by anthropometric measurements (height, weight). Physiological measures (HR, oxygen saturations (SpO2)) and patient-reported measures (Borg shortness of breath (SoB), rate of perceived exertion (RPE) and fatigue) were taken before and after the assessment. Statistical tests were performed between pre-test and post-test measures, and sex and body mass, and concurrent cardiopulmonary exercise tests (CPET) with 6MWT distance. RESULTS: The mean 6MWT distance was 705.5±86 m; males 709.4±86.9 m and females 685.9±81.9 m (p=0.32), with a median Borg SoB of 1 (IQR: 0-2) and RPE 9 (IQR: 7-11), and a negative correlation between body mass index and 6MWT distance, p=0.007. There were no significant differences between pre-test and post-test measures. Peak workload and VO2 Max correlated weakly with 6MWT distance (0.336, p=0.01 and 0.375, p=0.09, respectively), but submaximal CPET measures did not. CONCLUSION: These results provide a benchmark for British military 6MWT data to guide clinical and research use. However, a larger dataset is required for validation and normative values.

ABSTRACT

A key research theme identified during the 2021 Strategic Delivery Plan (SDP) for Defence Medical Services (DMS) Research was preventing and treating musculoskeletal injury (MSKI). MSKI is a significant burden to military populations globally, reducing both operational strength and force readiness. It is therefore essential that research is conducted to gain a greater understanding of the epidemiology, aetiology and risk factors associated with MSKI to develop targeted prevention strategies and rehabilitation interventions. The Academic Department of Military Rehabilitation (ADMR) and the recently established MSKI research-theme working group must use a combination of balance and flexibility when coordinating research priorities to ensure they align and reflect both higher level DMS and UK Defence Rehabilitation practitioner-driven priorities. This article describes the response ADMR have taken to meet and align with the requirements of the 2021 SDP.

ABSTRACT

BACKGROUND: Significant numbers of individuals struggle to return to work following acute coronavirus disease 2019 (COVID-19). The UK Military developed an integrated medical and occupational pathway (Defence COVID-19 Recovery Service, DCRS) to ensure safe return to work for those with initially severe disease or persistent COVID-19 sequalae. Medical deployment status (MDS) is used to determine ability to perform job role without restriction ('fully deployable', FD) or with limitations ('medically downgraded', MDG). AIMS: To identify which variables differ between those who are FD and MDG 6 months after acute COVID-19. Within the downgraded cohort, a secondary aim is to understand which early factors are associated with persistent downgrading at 12 and 18 months. METHODS: Individuals undergoing DCRS had comprehensive clinical assessment. Following this, their electronic medical records were reviewed and MDS extracted at 6, 12 and 18 months. Fifty-seven predictors taken from DCRS were analysed. Associations were sought between initial and prolonged MDG. RESULTS: Three hundred and twenty-five participants were screened, with 222 included in the initial analysis. Those who were initially downgraded were more likely to have post-acute shortness of breath (SoB), fatigue and exercise intolerance (objective and subjective), cognitive impairment and report mental health symptoms. The presence of fatigue and SoB, cognitive impairment and mental health symptoms was associated with MDG at 12 months, and the latter two, at 18 months. There were also modest associations between cardiopulmonary function and sustained downgrading. CONCLUSIONS: Understanding the factors that are associated with initial and sustained inability to return to work allows individualized, targeted interventions to be utilized.

ABSTRACT

INTRODUCTION: COVID-19 infection can precede, in a proportion of patients, a prolonged syndrome including fatigue, exercise intolerance, mood and cognitive problems. This study aimed to describe the profile of fatigue-related, exercise-related, mood-related and cognitive-related outcomes in a COVID-19-exposed group compared with controls. METHODS: 113 serving UK Armed Forces participants were followed up at 5, 12 (n=88) and 18 months (n=70) following COVID-19. At 18 months, 56 were in the COVID-19-exposed group with 14 matched controls. Exposed participants included hospitalised (n=25) and community (n=31) managed participants. 43 described at least one of the six most frequent symptoms at 5 months: fatigue, shortness of breath, chest pain, joint pain, exercise intolerance and anosmia. Participants completed a symptom checklist, patient-reported outcome measures (PROMs), the National Institute for Health cognitive battery and a 6-minute walk test (6MWT). PROMs included the Fatigue Assessment Scale (FAS), Generalised Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9) and Patient Checklist-5 (PCL-5) for post-traumatic stress. RESULTS: At 5 and 12 months, exposed participants presented with higher PHQ-9, PCL-5 and FAS scores than controls (ES (effect size) ≥0.25, p≤0.04). By 12 months, GAD-7 was not significantly different to controls (ES <0.13, p=0.292). Remaining PROMs lost significant difference by 18 months (ES ≤0.11, p≥0.28). No significant differences in the cognitive scales were observed at any time point (F=1.96, p=0.167). At 5 and 12 months, exposed participants recorded significantly lower distances on the 6MWT (ηp 2≥0.126, p<0.01). 6MWT distance lost significant difference by 18 months (ηp 2<0.039, p>0.15). CONCLUSIONS: This prospective cohort-controlled study observed adverse outcomes in depression, post-traumatic stress, fatigue and submaximal exercise performance up to 12 months but improved by 18-month follow-up, in participants exposed to COVID-19 compared with a matched control group.

ABSTRACT

Within the UK Armed Forces, musculoskeletal injuries account for over half of all medical downgrades and discharges. Data from other Armed Forces show that osteoarthritis (OA), more common in military personnel, is likely to contribute to this, both in its primary form and following injury (post-traumatic OA, PTOA), which typically presents in the third or fourth decade. OA is not a progressive 'wear and tear' disease, as previously thought, but a heterogenous condition with multiple aetiologies and modulators, including joint damage, abnormal morphology, altered biomechanics, genetics, low-grade inflammation and dysregulated metabolism. Currently, clinical diagnosis, based on symptomatic or radiological criteria, is followed by supportive measures, including education, exercise, analgesia, potentially surgical intervention, with a particular focus on exercise rehabilitation within the UK military. Developments in OA have led to a new paradigm of organ failure, with an emphasis on early diagnosis and risk stratification, prevention strategies (primary, secondary and tertiary) and improved aetiological classification using genotypes and phenotypes to guide management, with the introduction of biological markers (biomarkers) potentially having a role in all these areas. In the UK Armed Forces, there are multiple research studies focused on OA risk factors, epidemiology, biomarkers and effectiveness of different interventions. This review aims to highlight OA, especially PTOA, as an important diagnosis to consider in serving personnel, outline current and future management options, and detail current research trends within the Defence Medical Services.

ABSTRACT

INTRODUCTION: Combat-related traumatic injury (CRTI) has been linked to an increased cardiovascular disease (CVD) risk. The long-term impact of CRTI on heart rate variability (HRV)-a robust CVD risk marker-has not been explored. This study investigated the relationship between CRTI, the mechanism of injury and injury severity on HRV. METHODS: This was an analysis of baseline data from the ArmeD SerVices TrAuma and RehabilitatioN OutComE (ADVANCE) prospective cohort study. The sample consisted of UK servicemen with CRTI sustained during deployment (Afghanistan, 2003-2014) and an uninjured comparison group who were frequency matched to the injured group based on age, rank, deployment period and role in theatre. Root mean square of successive differences (RMSSD) was measured as a measure of ultrashort term HRV via <16 s continuous recording of the femoral arterial pulse waveform signal (Vicorder). Other measures included injury severity (New Injury Severity Scores (NISS)) and injury mechanism. RESULTS: Overall, 862 participants aged 33.9±5.4 years were included, of whom 428 (49.6%) were injured and 434 (50.3%) were uninjured. The mean time from injury/deployment to assessment was 7.91±2.05 years. The median (IQR) NISS for those injured was 12 (6-27) with blast being the predominant injury mechanism (76.8%). The median (IQR) RMSSD was significantly lower in the injured versus the uninjured (39.47 ms (27.77-59.77) vs 46.22 ms (31.14-67.84), p<0.001). Using multiple linear regression (adjusting for age, rank, ethnicity and time from injury), geometric mean ratio (GMR) was reported. CRTI was associated with a 13% lower RMSSD versus the uninjured group (GMR 0.87, 95% CI 0.80-0.94, p<0.001). A higher injury severity (NISS ≥25) (GMR 0.78, 95% CI 0.69-0.89, p<0.001) and blast injury (GMR 0.86, 95% CI 0.79-0.93, p<0.001) were also independently associated with lower RMSSD. CONCLUSION: These results suggest an inverse association between CRTI, higher severity and blast injury with HRV. Longitudinal studies and examination of potential mediating factors in this CRTI-HRV relationship are needed.

ABSTRACT

Coronavirus disease 2019 (COVID-19) causes significant mortality and morbidity, with an unknown impact in the medium to long term. Evidence from previous coronavirus epidemics indicates that there is likely to be a substantial burden of disease, potentially even in those with a mild acute illness. The clinical and occupational effects of COVID-19 are likely to impact on the operational effectiveness of the Armed Forces. Collaboration between Defence Primary Healthcare, Defence Secondary Healthcare, Defence Rehabilitation and Defence Occupational Medicine resulted in the Defence Medical Rehabilitation Centre COVID-19 Recovery Service (DCRS). This integrated clinical and occupational pathway uses cardiopulmonary assessment as a cornerstone to identify, diagnose and manage post-COVID-19 pathology.

ABSTRACT

INTRODUCTION: Establishing research priorities help to address knowledge gaps and exploit emerging opportunities to develop a clinical evidence base. The previous clinical engagement exercise to determine UK Defence Rehabilitation practitioner-based research priorities was conducted in 2014. The aim of this article is to (1) describe how research priorities are established for UK Defence Rehabilitation; (2) review, reassess and rate the priorities highlighted and set by rehabilitation practitioners following the 2014 survey and (3) identify new rehabilitation research themes and topics reflecting 2020 priorities. METHODS: Stage 1: delegates (n=72) at the October 2019 Defence Medical Services Rehabilitation Conference participated in a series of focus group workshops. Stage 2: an online survey circulated through the military chain of command to all Defence Primary Health Care clinical rehabilitation staff. Stage 3: a thematic analysis of all survey submissions yielding a ranked order of priority by topic. RESULTS: 165 clinical rehabilitation staff completed an online survey. 'Rehabilitation outcomes', 'Psychological factors in rehabilitation' and 'Residential/Inpatient treatment paradigm' emerged as three clear research priorities across all three tiers of UK Defence Rehabilitation. New research priorities emerging from the 2020 survey were 'lifestyle factors during rehabilitation', 'management of pain during rehabilitation' and 'anterior knee pain'. CONCLUSION: It is essential that funding directed to musculoskeletal rehabilitation focuses on the highest research priorities in the field to ensure optimum health return on investment. The results of this survey will assist in guiding the clinical research being conducted within UK Defence Rehabilitation over the next five years.

ABSTRACT

INTRODUCTION: Correcting adverse biomechanics is key in rehabilitating musculoskeletal injuries. Verbal instruction remains the primary method for correcting biomechanics and therefore a patient's understanding of these instructions is believed to directly influence treatment outcomes. The aim of this study was to establish the patients' perceptions of virtual reality-based gait education (VR-GEd) and to assess its influence on the standard military rehabilitation outcomes. METHODS: A retrospective analysis using routinely collected data was performed. Twenty patients with lower-limb musculoskeletal injuries undertook a VR-GEd session on the commencement of a 3-week, multidisciplinary, inpatient course of rehabilitation. Patient outcomes were compared with a group of matched controls, completing the same standardised course of inpatient treatment. RESULTS: The VR-GEd group exhibited greater reductions the interference pain had on their mood (p=0.022). Improvements in generalised anxiety (p=0.029) were greater in the VR-GEd group but were not large enough to be clinically meaningful. VR-GEd did not influence functional outcomes. Patients rated the sessions highly in terms of enjoyment and perceived value. Patient feedback highlighted that they understood their injury better and felt the session could positively influence their recovery. CONCLUSION: VR-GEd was proven to be an enjoyable and valued means of educating military inpatients about their injury mechanics. This study found no contraindications for the inclusion of VR-GEd in current rehabilitation programmes. However, current evidence suggests a single VR-GEd session cannot act as a replacement for biofeedback interventions, due to the lack of enhanced improvement across rehabilitation outcomes.

ABSTRACT

INTRODUCTION: Despite the high prevalence of musculoskeletal injuries, there is a shortage of data quantifying the risk factors attributable to cumulative occupational demands among UK Military personnel. We developed a new comprehensive questionnaire that examines occupational and operational physical loading during military service. The aim of this study was to examine the test-retest reliability of the Military Physical Loading Questionnaire (MPLQ). METHODS: Intraclass correlation coefficients (ICC) were used to evaluate the test-retest reliability (4-week interval) of the MPLQ on 18 occupational and 18 operational items in 50 male (mean age: 36 years; SD ±7.9) UK military personnel. A stratified analysis based on duration of Service (0-10 years, 11-20 years and ≥21 years) was conducted to assess whether stability of task items was dependent on participant length of recall. Internal consistency was assessed by Cronbach's alpha (α) coefficients. RESULTS: Reliability of individual operational items ranged from fair to almost perfect agreement (ICC range: 0.37-0.89; α range: 0.53-0.94) with most items demonstrating moderate to substantial reliability. Overall scores related to occupational items showed substantial to almost perfect agreement between administrations (ICC range: 0.73-0.94; α range: 0.84-0.96). Stratifying by duration of Service showed similar within group reliability to the entire sample and no pattern of decreasing or increasing reliability with length of recall period was observed. CONCLUSIONS: It is essential that data used in planning UK military policy and health services are as accurate as possible. This study provides preliminary support for the MPLQ as a reliable self-report instrument for assessing the cumulative lifelong effects of occupational loading in UK military personnel. Further validation studies using larger and more demographically diverse military populations will support its interpretation in future epidemiological research.

ABSTRACT

INTRODUCTION: Hip and groin related pain is a common complaint among the military population across UK Defence Rehabilitation and addressing associated biomechanical dysfunction is a key treatment goal. Personnel are exposed to complex occupational loads, therefore assessing movement during demanding tasks may expose biomechanical deficits. Observing biomechanical and clinical outcomes in response to treatment is therefore an important consideration. The aims were to examine clinical and biomechanical outcomes prior to (T1) and 12 weeks post (T2) inpatient rehabilitation and explore the influence of pathological subgroup. METHODS: Prospective cohort study as part of a clinical service evaluation of 25 patients undergoing treatment for hip and groin related pain. Three-dimensional motion capture (3DM) during a single-leg squat, hip strength and patient-reported outcome measures were collected at T1 and T2. RESULTS: Increased abductor and external rotator strength with reductions in contralateral pelvic drop (1.9°; p=0.041) at T2 on the injured side. Pain reduced by 9.6 mm (p=0.017) but no differences were found for Non-Arthritic Hip Score (NAHS). No statistically significant differences were found between pathological subgroups. Kinematic profiles display variation between diagnostic subgroups and response to treatment. CONCLUSION: Strength and pain improved with treatment in this service evaluation although biomechanical adaptation and NAHS remain inconclusive. Small and uneven sample size prevents a firm conclusion regarding the effect of pathological subgroupings, however, the data can be considered hypothesis generating for future, larger studies to integrate 3DM for monitoring response to rehabilitation in pathological subgroups to support clinical decision making.

ABSTRACT

INTRODUCTION: Low back pain (LBP) has been reported as the most common reason for presentation to the Medical Centre in the British Military, and the most common re-referral for the same condition. In 2015, the UK Defence Medical Rehabilitation Centre (DMRC) adopted a cognitive functional therapy (CFT) approach to spinal rehabilitation in line with National Institute for Health and Care Excellence and military best practice guidelines. The aim of this study is to evaluate the functional and psychosocial outcomes of all patients with chronic LBP treated with CFT-based multidisciplinary rehabilitation at DMRC, Headley Court. METHODS: A prospective observational service evaluation of British Military patients (n=238) with LBP who attended 3 weeks of inpatient multidisciplinary CFT-based programme from 2015 to the end of 2017 at DMRC was analysed. Functional outcomes include: multistage locomotion test (MSLT) and sit and reach test. Psychosocial outcomes include: Tampa Scale of Kinesiophobia, Oswestry Disability Index, Brief Pain Inventory (BPI), General Anxiety Disorder-7 and Patient Health Questionnaire-9. RESULTS: There were significant improvements in endurance (MSLT), range of motion, kinesiophobia, pain-related lifestyle interference (BPI-Lifestyle), anxiety and depression (p≤0.001). However, no improvements in pain intensity (BPI-Intensity) were demonstrated (p>0.05). CONCLUSION: After 3 weeks of CFT-based multidisciplinary rehabilitation, function and psychosocial health improved with symptoms of pain being less obtrusive to activities of daily activity. There were however no patient-reported reductions in pain intensity. The improvements demonstrated are indicative of outcomes that facilitate greater integration back to work or into society.

ABSTRACT

INTRODUCTION: Individuals with delayed below-knee amputation have previously reported superior clinical outcomes compared with lower limb reconstruction. The UK military have since introduced a passive-dynamic ankle-foot orthosis (PDAFO) into its rehabilitation care pathway to improve limb salvage outcomes. The aims were to determine if wearing a PDAFO improves medium-term clinical outcomes and what influence does multidisciplinary team (MDT) rehabilitation have after PDAFO fitting? Also, what longitudinal changes in clinical outcomes occur with MDT rehabilitation and how do these results compare with patients with previous lower extremity trauma discharged prior to PDAFO availability? METHODS: We retrospectively evaluated levels of mobility, activities of daily living, anxiety, depression and pain in a heterogeneous group of 23 injured UK servicemen 34±11 months after PDAFO provision. We also retrospectively analysed 16 patients across four time points (pre-PDAFO provision, first, second and final inpatient admissions post-PDAFO provision) using identical outcome measures, plus the 6 min walk test. RESULTS: Outcomes were compared with previous below-knee limb salvage and amputees. Before PDAFO, 74% were able to walk and 4% were able to run independently. At follow-up, this increased to 91% and 57%, respectively. Mean depression and anxiety scores remained stable over time (p>0.05). After 3 weeks, all patients could walk independently (pre-PDAFO=31%). Mean 6 min walk distance significantly increased from 440±75 m (pre-PDAFO) to 533±68 m at last admission (p=0.003). The ability to run increased from 6% to 44% after one admission. CONCLUSIONS: All functional and most psychosocial outcomes in PDAFO users were superior to previous limb salvage and comparable to previous below-knee amputees. The PDAFO facilitated favourable short-term and medium-term changes in all clinical outcome measurements.

ABSTRACT

Amputees are known to walk with greater metabolic cost than able-bodied individuals and establishing predictors of metabolic cost from kinematic measures, such as centre of mass (CoM) motion, during walking are important from a rehabilitative perspective, as they can provide quantifiable measures to target during gait rehabilitation in amputees. While it is known that vertical CoM motion poorly predicts metabolic cost, CoM motion in the medial-lateral (ML) and anterior-posterior directions have not been investigated in the context of gait efficiency in the amputee population. Therefore, the aims of this study were to investigate the relationship between CoM motion in all three directions of motion, base of support and walking speed, and the metabolic cost of walking in both able-bodied individuals and different levels of lower limb amputee. 37 individuals were recruited to form groups of controls, unilateral above- and below-knee, and bilateral above-knee amputees respectively. Full-body optical motion and oxygen consumption data were collected during walking at a self-selected speed. CoM position was taken as the mass-weighted average of all body segments and compared to each individual's net non-dimensional metabolic cost. Base of support and ML CoM displacement were the strongest correlates to metabolic cost and the positive correlations suggest increased ML CoM displacement or Base of support will reduce walking efficiency. Rehabilitation protocols which indirectly reduce these indicators, rather than vertical CoM displacement will likely show improvements in amputee walking efficiency.

ABSTRACT

Reduced capacity and increased metabolic cost of walking occurs in amputees, despite advances in prosthetic componentry. Joint powers can quantify deficiencies in prosthetic gait, but do not reveal how energy is exchanged between limb segments. This study aimed to quantify these energy exchanges during amputee walking. Optical motion and forceplate data collected during walking at a self-selected speed for cohorts of 10 controls, 10 unilateral trans-tibial, 10 unilateral trans-femoral and 10 bilateral trans-femoral amputees were used to determine the energy exchanges between lower limb segments. At push-off, consistent thigh and shank segment powers were observed between amputee groups (1.12W/kg vs. 1.05W/kg for intact limbs and 0.97W/kg vs. 0.99W/kg for prosthetic limbs), and reduced prosthetic ankle power, particularly in trans-femoral amputees (3.12W/kg vs. 0.87W/kg). Proximally-directed energy exchange was observed in the intact limbs of amputees and controls, while prosthetic limbs displayed distally-directed energy exchanges at the knee and hip. This study used energy flow analysis to show a reversal in the direction in which energy is exchanged between prosthetic limb segments at push-off. This reversal was required to provide sufficient energy to propel the limb segments and is likely a direct result of the lack of push-off power at the prosthetic ankle, particularly in trans-femoral amputees, and leads to their increased metabolic cost of walking.

ABSTRACT

BACKGROUND: Femoroacetabular impingement (FAI) is common with an estimated prevalence of 10-15% among young active individuals. The natural history of the disorder is progression to early osteoarthritis. Hip arthroscopy is recommended if conservative treatments fail; however, outcomes are unclear, particularly in highly active populations. AIM: To evaluate the functional and vocational outcome of hip arthroscopy, as part of an evidence-based rehabilitation hip pain pathway, for the treatment of FAI in an active military population. METHODS: All patients in the defence rehabilitation hip pain pathway, with a confirmed diagnosis of FAI who failed conservative treatment, were assessed prior to surgery and at 2, 6 and 12 months postsurgery. Outcome measures included the Visual Analogue Scale (VAS) for hip pain, Non-Arthritic Hip Score (NAHS) for function, and vocational assessments including functional activity assessment (FAA) and Joint Medical Employment Standard for military employability and deployability. RESULTS: 101 patients completed the study (mean age=33 years) (male:female:75:26) (Royal Navy/British Army/Royal Air Force: 13%/48%/39%). Outcomes demonstrated significant improvements with large effect size. Preoperative NAHS mean=62.9 (SD 16.4), 12-month postoperative NAHS mean=78.8 (18.3), mean improvement in NAHS=15.9 (95% CI 12.3 to 19.5, p<0.001). Preoperative VAS pain mean=51.3 (20.9), 12-month postoperative VAS pain=25.6 (24.5). Mean improvement 25.7 (95% CI 19.4 to 31.99, p<0.001). 73% of patients had a deployable medical category at 12 months postoperative. CONCLUSIONS: These data confirm that hip arthroscopy as part of a structured evidence-based multidisciplinary care pathway produces significant and continued symptomatic, functional and vocational improvements over a 12-month period in a military population exposed to high intensity, weight-bearing exercise in uncontrolled and unforgiving environments.

ABSTRACT

BACKGROUND: Recent military operations in Afghanistan have resulted in considerable lower limb trauma. Associated with this trauma have been serious injuries to the genitalia. No previous study has looked at the effect of traumatic genital injury on the individual. This study expresses the impact of these injuries. METHODS: A qualitative evaluation, interviewing 13 male patients with extensive genital injuries, including 11 patients with orchidectomies. RESULTS: Patients attach a very high importance to their genital injury, rating this injury as having more impact than lower limb amputations. They also have a high expectation for the recovery of sexual function. Psychological outcomes are better when an individual's future fertility is known at an early stage. CONCLUSION: Better outcomes are achieved for the patient when psychological and surgical support if provided throughout the long treatment and recovery process It is important that every effort is made to preserve fertility right from the point of injury.

ABSTRACT

OBJECTIVES: The British military has a cohort of patients with ankylosing spondylitis (AS) characterised by young age and short disease duration. Many of the most severely affected AS patients have been treated since 2005 at Headley Court with anti-tumour necrosis factor (anti-TNF) therapy in accordance with National Institute of Health and Care Excellence guidance. We wanted to prospectively determine both the safety and efficacy of this new treatment in our British military population and compare this with relevant civilian study outcome data. METHODS: All AS patients commenced on anti-TNF therapy at Headley Court were prospectively monitored for treatment efficacy and side effects. Outcome measures used included the Bath Ankylosing Spondylitis Disease Activity Index. Our results were compared with a civilian comparison group (NHS) and relevant landmark clinical trial data. RESULTS: Our patients were younger (mean age 34.7 years) and had a shorter duration (mean disease duration 6.9 years) than the civilian (NHS) comparison group. Our safety data were extremely benign with only two patients suffering minor side effects (local injection site reaction). Furthermore, our outcome data were superior to both NHS routine care and to landmark clinical studies. DISCUSSION: Prior to this study, there were no data on military AS populations receiving anti-TNF therapy. The study confirms British military patients tolerate this therapy extremely well and receive greater benefit from this treatment than that seen in any published study to date. We believe that this confirms that young age and short disease duration are good prognostic factors in the treatment of AS with anti-TNF therapy.
