Comparison of surgical or non-surgical management for non-acute anterior cruciate ligament injury: the ACL SNNAP RCT.

Background: Anterior cruciate ligament injury of the knee is common and leads to decreased activity and risk of secondary osteoarthritis of the knee. Management of patients with a non-acute anterior cruciate ligament injury can be non-surgical (rehabilitation) or surgical (reconstruction). However, insufficient evidence exists to guide treatment. Objective(s): To determine in patients with non-acute anterior cruciate ligament injury and symptoms of instability whether a strategy of surgical management (reconstruction) without prior rehabilitation was more clinically and cost-effective than non-surgical management (rehabilitation). Design: A pragmatic, multicentre, superiority, randomised controlled trial with two-arm parallel groups and 1:1 allocation. Due to the nature of the interventions, no blinding could be carried out. Setting: Twenty-nine NHS orthopaedic units in the United Kingdom. Participants: Participants with a symptomatic (instability) non-acute anterior cruciate ligament-injured knee. Interventions: Patients in the surgical management arm underwent surgical anterior cruciate ligament reconstruction as soon as possible and without any further rehabilitation. Patients in the rehabilitation arm attended physiotherapy sessions and only were listed for reconstructive surgery on continued instability following rehabilitation. Surgery following initial rehabilitation was an expected outcome for many patients and within protocol. Main outcome measures: The primary outcome was the Knee Injury and Osteoarthritis Outcome Score 4 at 18 months post randomisation. Secondary outcomes included return to sport/activity, intervention-related complications, patient satisfaction, expectations of activity, generic health quality of life, knee-specific quality of life and resource usage. Results: Three hundred and sixteen participants were recruited between February 2017 and April 2020 with 156 randomised to surgical management and 160 to rehabilitation. Forty-one per cent (n = 65) of those allocated to rehabilitation underwent subsequent reconstruction within 18 months with 38% (n = 61) completing rehabilitation and not undergoing surgery. Seventy-two per cent (n = 113) of those allocated to surgery underwent reconstruction within 18 months. Follow-up at the primary outcome time point was 78% (n = 248; surgical, n = 128; rehabilitation, n = 120). Both groups improved over time. Adjusted mean Knee Injury and Osteoarthritis Outcome Score 4 scores at 18 months had increased to 73.0 in the surgical arm and to 64.6 in the rehabilitation arm. The adjusted mean difference was 7.9 (95% confidence interval 2.5 to 13.2; p = 0.005) in favour of surgical management. The per-protocol analyses supported the intention-to-treat results, with all treatment effects favouring surgical management at a level reaching statistical significance. There was a significant difference in Tegner Activity Score at 18 months. Sixty-eight per cent (n = 65) of surgery patients did not reach their expected activity level compared to 73% (n = 63) in the rehabilitation arm. There were no differences between groups in surgical complications (n = 1 surgery, n = 2 rehab) or clinical events (n = 11 surgery, n = 12 rehab). Of surgery patients, 82.9% were satisfied compared to 68.1% of rehabilitation patients. Health economic analysis found that surgical management led to improved health-related quality of life compared to non-surgical management (0.052 quality-adjusted life-years, p = 0.177), but with higher NHS healthcare costs (£1107, p < 0.001). The incremental cost-effectiveness ratio for the surgical management programme versus rehabilitation was £19,346 per quality-adjusted life-year gained. Using £20,000-30,000 per quality-adjusted life-year thresholds, surgical management is cost-effective in the UK setting with a probability of being the most cost-effective option at 51% and 72%, respectively. Limitations: Not all surgical patients underwent reconstruction, but this did not affect trial interpretation. The adherence to physiotherapy was patchy, but the trial was designed as pragmatic. Conclusions: Surgical management (reconstruction) for non-acute anterior cruciate ligament-injured patients was superior to non-surgical management (rehabilitation). Although physiotherapy can still provide benefit, later-presenting non-acute anterior cruciate ligament-injured patients benefit more from surgical reconstruction without delaying for a prior period of rehabilitation. Future work: Confirmatory studies and those to explore the influence of fidelity and compliance will be useful.

The study aimed to find out whether it is better to offer surgical reconstruction or rehabilitation first to patients with a more long-standing injury of their anterior cruciate ligament in their knee. This injury causes physical giving way of the knee and/or sensations of it being wobbly (instability). The instability can affect daily activities, work, sport and can lead to arthritis. There are two main treatment options for this problem: non-surgical rehabilitation (prescribed exercises and advice from physiotherapists) or an operation by a surgeon to replace the damaged ligament (anterior cruciate ligament reconstruction). Although studies have highlighted the best option for a recently injured knee, the best management was not known for patients with a long-standing injury, perhaps occurring several months previously. Because the surgery is expensive to the NHS (around £100 million per year), it was also important to look at the costs involved. We carried out a study recruiting 316 non-acute anterior cruciate ligament-injured patients from 29 different hospitals and allocated each patient to either surgery or rehabilitation as their treatment option. We measured how well they did with special function and activity scores, patient satisfaction and costs of treatment. Patients in both groups improved substantially. It was expected that some patients in the rehabilitation group would want surgery if non-surgical management was unsuccessful. Forty-one per cent of patients who initially underwent rehabilitation subsequently elected to have reconstructive surgery. Overall, the patients allocated to the surgical reconstruction group had better results in terms of knee function and stability, activity level and satisfaction with treatment than patients allocated to the non-operative rehabilitation group. There were few problems or complications with either treatment option. Although the surgery was a more expensive treatment option, it was found to be cost-effective in the UK setting. The evidence can be discussed in shared decision-making with anterior cruciate ligament-injured patients. Both strategies of management led to improvement. Although a rehabilitation strategy can be beneficial, especially for recently injured patients, it is advised that later-presenting non-acute and more long-standing anterior cruciate ligament-injured patients undergo surgical reconstruction without necessarily delaying for a period of rehabilitation.

Subjective assessment reported by patients shows differences between single-bundle and double-bundle anterior cruciate ligament reconstruction, systematic review and meta-analysis.

To determine the functional recovery, active reincorporation, and anteroposterior and rotational stability of patients undergoing anterior cruciate ligament (ACL) reconstruction using arthroscopy techniques with simple-bundle (SB) or double-bundle (DB). The following databases were searched: PubMed, Embase (Elsevier platform), the Cochrane Central Register of Controlled Trials (Wiley platform), Web of Science, and CINAHL. Level I and II studies involving anterior cruciate ligament arthroscopy were included in the search. Records were screened by title and abstract and assessed the risk of bias of selected studies. Meta-analyses using RevMan 5.3 software were conducted on the following outcomes: knee functionality, objective measurements of knee stability, rotational knee stability and knee anterior stability, sports reincorporation, and subjective assessments. Twenty-four studies of patients undergoing ACL reconstruction were included in the qualitative and quantitative synthesis (1707 patients) for Lysholm score, Subjective International Knee Documentation Committee (IKDC) score, Tegner score, KT-1000/2000, Lachman test, Objective IKDC score, and Pivot-Shift test. A return to pre-injury level showed a significant decrease in the Lysholm score (mean difference, - 0.99; 95% CI - 1.71 to - 0.40; P = 0.007) and Tegner score (mean difference, - 0.07; 95% CI, - 0.13 to - 0.01; P = 0.02) at DB reconstruction, similar to the knee functionality outcome of the subjective IKDC score (mean difference - 1.42; 95% CI - 2.46 to - 0.38; P = 0.007). There is no clear or significant difference in clinical stability and knee function or in sports incorporation with the true difference occurring in the subjective assessment.

Orthotic management of instability of the knee related to neuromuscular and central nervous system disorders: qualitative interview study of patient perspectives.

OBJECTIVES: Adults with knee instability related to neuromuscular disorders or central nervous conditions often experience mobility problems and rely on orthoses to improve function and mobility. Patient views of device effectiveness and acceptability are underexplored. Our study aimed to elicit device users' perspectives regarding fitting, acceptability, effectiveness and use of orthoses, and identify important treatment outcomes. DESIGN: Qualitative descriptive study using in-depth semistructured interviews. Interview transcriptions were coded and thematically analysed, using 'Framework'. SETTING AND PARTICIPANTS: A purposive sample of 24 adult users of orthotic devices. Nineteen patients were recruited across three National Health Service sites, and five people through charities/patient support groups in England. Half of the participants had been diagnosed with poliomyelitis, and the remainder with multiple sclerosis, Charcot-Marie-Tooth disease, spinal injury or spina bifida, and stroke. The median age of participants was 64.5 years (range 36-80 years). RESULTS: Patients' medical condition impacted significantly on daily life. Participants relied on orthotic devices to enable engagement in daily activities. Patient goals for mobility were linked to individual circumstances. Desired treatment outcomes included reduction in pain, trips and falls, with improved balance and stability. Effectiveness, reliability, comfort and durability were the most valued features of orthoses and associated with reported use. Obtaining suitable footwear alongside orthotic devices was a significant concern. Time pressures during device fitting were viewed negatively. CONCLUSIONS: Orthotic devices for knee instability play a crucial role in promoting, maintaining and enhancing physical and psychological health and well-being, enabling patients to work, engage in family life and enjoy social activities. Future research should consider how best to measure the impact of orthotic devices on patient quality of life and daily functioning outside the clinic setting, as well as device use and any adverse effects. TRIAL REGISTRATION NUMBER: This qualitative study was retrospectively registered as Current Controlled Trials ISRCTN65240228.

Current Trends in the Management of Lateral Ankle Sprain in the United States.

OBJECTIVE: To characterize trends in the acute management (within 30 days) after lateral ankle sprain (LAS) in the United States. DESIGN: Descriptive epidemiology study. PATIENTS: Of note, 825 718 ankle sprain patients were identified; 96.2% were patients with LAS. Seven percent had an associated fracture and were excluded from the remaining analysis. SETTING: Primary and tertiary care settings. INTERVENTIONS: We queried a database of national health insurance records for 2007 to 2011 by ICD-9 codes for patients with LAS while excluding medial and syndesmotic sprains and any LAS with an associated foot or ankle fracture. MAIN OUTCOME MEASURES: The percentage of patients to receive specific diagnostic imaging, orthopedic devices, or physical therapy treatments within 30 days of the LAS diagnosis and the associated costs. RESULTS: Over two-thirds of patients with LAS without an associated fracture received radiographs, 9% received an ankle brace, 8.1% received a walking boot, 6.5% were splinted, and 4.8% were prescribed crutches. Only 6.8% received physical therapy within 30 days of their LAS diagnosis, 94.1% of which performed therapeutic exercise, 52.3% received manual therapy, and 50.2% received modalities. The annual cost associated with physician visits, diagnostic imaging, orthopedic devices, and physical therapy was 152 million USD, 81.5% was from physician evaluations, 7.9% from physical therapy, 7.2% from diagnostic imaging, and 3.4% from orthopedic devices. CONCLUSIONS: Most patients with LAS do not receive supervised rehabilitation. The small proportion of patients with LAS to receive physical therapy get rehabilitation prescribed in accordance with clinical practice guidelines. The majority (>80%) of the LAS financial burden is associated with physician evaluations.

Orthotic management of instability of the knee related to neuromuscular and central nervous system disorders: systematic review, qualitative study, survey and costing analysis.

BACKGROUND: Patients who have knee instability that is associated with neuromuscular disease (NMD) and central nervous system (CNS) conditions can be treated using orthoses, such as knee-ankle-foot orthoses (KAFOs). OBJECTIVES: To assess existing evidence on the effectiveness of orthoses; patient perspectives; types of orthotic devices prescribed in the UK NHS; and associated costs. METHODS: Qualitative study of views of orthoses users - a qualitative in-depth interview study was undertaken. Data were analysed for thematic content. A coding scheme was developed and an inductive approach was used to identify themes. Systematic review - 18 databases were searched up to November 2014: MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, Cumulative Index to Nursing and Allied Health, EMBASE, PASCAL, Scopus, Science Citation Index, BIOSIS Previews, Physiotherapy Evidence Database, Recal Legacy, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Health Technology Assessment database, Cochrane Central Register of Controlled Trials, Conference Proceedings Citation Index: Science, Health Management Consortium, ClinicalTrials.gov, International Clinical Trials Registry Platform and National Technical Information Service. Studies of adults using an orthosis for instability of the knee related to NMD or a CNS disorder were included. Data were extracted and quality was assessed by two researchers. Narrative synthesis was undertaken. Survey and costing analysis - a web survey of orthotists, physiotherapists and rehabilitation medicine physicians was undertaken. Telephone interviews with orthotists informed a costing analysis. RESULTS: Qualitative study - a total of 24 people participated. Potential for engagement in daily activities was of vital importance to patients; the extent to which their device enabled this was the yardstick by which it was measured. Patients' prime desired outcome was a reduction in pain, falls or trips, with improved balance and stability. Effectiveness, reliability, comfort and durability were the most valued features of orthoses. Many expressed frustration with perceived deficiencies in service provision relating to appointment and administrative systems and referral pathways. Systematic review - a total of 21 studies (478 participants) were included of people who had post-polio syndrome, inclusion body myositis, were post stroke or had spinal cord injury. The studies evaluated KAFOs (mainly carbon fibre), stance control KAFO and hip KAFOs. All of the studies were at risk of bias and, in general, were poorly reported. Survey and costing analysis - in total, 238 health-care professionals responded. A range of orthoses is prescribed for knee instability that is related to NMD or CNS conditions, approximately half being custom-made. At least 50% of respondents thought that comfort and confidence in mobility were extremely important treatment outcomes. The cost of individual KAFOs was highly variable, ranging from £73 to £3553. CONCLUSIONS: Various types of orthoses are used in the NHS to manage patients with NMD/CNS conditions and knee instability, both custom-made and prefabricated, of variable cost. Evidence on the effectiveness of the orthoses is limited, especially in relation to the outcomes that are important to orthoses users. LIMITATIONS: The population included was broad, limiting any in-depth consideration of specific conditions. The response rate to the survey was low, and the costing analysis was based on some assumptions that may not reflect the true costs of providing KAFOs. FUTURE WORK: Future work should include high-quality research on the effectiveness and cost-effectiveness of orthoses; development of a core set of outcome measures; further exploration of the views and experiences of patients; and the best models of service delivery.

The feasibility of a randomised controlled trial of physiotherapy for adults with joint hypermobility syndrome.

BACKGROUND: Joint hypermobility syndrome (JHS) is a heritable disorder associated with laxity and pain in multiple joints. Physiotherapy is the mainstay of treatment, but there is little research investigating its clinical effectiveness. OBJECTIVES: To develop a comprehensive physiotherapy intervention for adults with JHS; to pilot the intervention; and to conduct a pilot randomised controlled trial (RCT) to determine the feasibility of conducting a future definitive RCT. DESIGN: Patients' and health professionals' perspectives on physiotherapy for JHS were explored in focus groups (stage 1). A working group of patient research partners, clinicians and researchers used this information to develop the physiotherapy intervention. This was piloted and refined on the basis of patients' and physiotherapists' feedback (stage 2). A parallel two-arm pilot RCT compared 'advice' with 'advice and physiotherapy' (stage 3). Random allocation was via an automated randomisation service, devised specifically for the study. Owing to the nature of the interventions, it was not possible to blind clinicians or patients to treatment allocation. SETTING: Stage 1 - focus groups were conducted in four UK locations. Stages 2 and 3 - piloting of the intervention and the pilot RCT were conducted in two UK secondary care NHS trusts. PARTICIPANTS: Stage 1 - patient focus group participants (n = 25, three men) were aged > 18 years, had a JHS diagnosis and had received physiotherapy within the preceding 12 months. The health professional focus group participants (n = 16, three men; 14 physiotherapists, two podiatrists) had experience of managing JHS. Stage 2 - patient participants (n = 8) were aged > 18 years, had a JHS diagnosis and no other musculoskeletal conditions causing pain. Stage 3 - patient participants for the pilot RCT (n = 29) were as for stage 2 but the lower age limit was 16 years. INTERVENTION: For the pilot RCT (stage 3) the advice intervention was a one-off session, supplemented by advice booklets. All participants could ask questions specific to their circumstances and receive tailored advice. Participants were randomly allocated to 'advice' (no further advice or physiotherapy) or 'advice and physiotherapy' (an additional six 30-minute sessions over 4 months). The physiotherapy intervention was supported by a patient handbook and was delivered on a one-to-one patient-therapist basis. It aimed to increase patients' physical activity through developing knowledge, understanding and skills to better manage their condition. MAIN OUTCOME MEASURES: Data from patient and health professional focus groups formed the main outcome from stage 1. Patient and physiotherapist interview data also formed a major component of stages 2 and 3. The primary outcome in stage 3 related to the feasibility of a future definitive RCT [number of referrals, recruitment and retention rates, and an estimate of the value of information (VOI) of a future RCT]. Secondary outcomes included clinical measures (physical function, pain, global status, self-reported joint count, quality of life, exercise self-efficacy and adverse events) and resource use (to estimate cost-effectiveness). Outcomes were recorded at baseline, 4 months and 7 months. RESULTS: Stage 1 - JHS is complex and unpredictable. Physiotherapists should take a long-term holistic approach rather than treating acutely painful joints in isolation. Stage 2 - a user-informed physiotherapy intervention was developed and evaluated positively. Stage 3 - recruitment to the pilot RCT was challenging, primarily because of a perceived lack of equipoise between advice and physiotherapy. The qualitative evaluation provided very clear guidance to inform a future RCT, including enhancement of the advice intervention. Some patients reported that the advice intervention was useful and the physiotherapy intervention was again evaluated very positively. The rate of return of questionnaires was low in the advice group but reasonable in the physiotherapy group. The physiotherapy intervention showed evidence of promise in terms of primary and secondary clinical outcomes. The advice arm experienced more adverse events. The VOI analysis indicated the potential for high value from a future RCT. Such a trial should form the basis of future research efforts. CONCLUSION: A future definitive RCT of physiotherapy for JHS seems feasible, although the advice intervention should be made more robust to address perceived equipoise and subsequent attrition.

Diagnosis, Management and Assessment of Adults with Joint Hypermobility Syndrome: A UK-Wide Survey of Physiotherapy Practice.

Joint hypermobility syndrome (JHS) is a heritable disorder associated with excessive joint range of motion and pain in the absence of inflammatory joint disease. It is a relatively common cause of musculoskeletal pain but is generally understood to be under-recognized and poorly managed in clinical practice. The present study therefore aimed to identify how JHS is diagnosed, managed and assessed in routine physiotherapy practice. A survey tool was developed from similar physiotherapy surveys of musculoskeletal practice, a review of the literature, and consultation with researchers and clinicians. Paper copies of the final survey were sent to 201 randomly selected secondary care organizations across the UK and an electronic version was advertised through physiotherapy professional networks. A total of 66 responses (80% women) were received from physiotherapists, with a wide range of clinical experience. Only 32% of respondents reported that they had received formal training in JHS management. The Brighton diagnostic criteria for JHS were not often used (only 31% of respondents). The stated aims of physiotherapy and the specific interventions employed seem well matched, with a focus on advice, education, exercise and self-management. Although pain relief was not reported as a high priority in terms of treatment aims, pain was most often assessed as an outcome, suggesting a mismatch between what clinicians aim to achieve and what they measure. The results suggest that reported management strategies are broadly appropriate to long-term musculoskeletal conditions but additional training specific to JHS may be required, particularly in diagnosis and assessment.

Application of the sit-to-stand movement for the early assessment of functional deficits in patients who underwent anterior cruciate ligament reconstruction.

OBJECTIVE: The aims of this study were to identify and quantify functional deficits between the involved and the uninvolved limb as early as 1 mo after ACL reconstruction by means of a sit-to-stand movement on two force platforms. DESIGN: Ground reaction forces were measured in 73 patients who underwent ACL reconstruction, 47 with patellar tendon autograft and 26 with hamstring tendon autograft (ACL-H), and in 22 controls, who stood up from a seat as fast as possible. Side-to-side limb symmetry index (LSI) was calculated for peak force and rate of force development. RESULTS: The LSI of vertical peak force was 59% in the patellar tendon autograft group and 68% in the ACL-H group, which were both lower than the 95% LSI of the controls (P < 0.001). The LSI of rate of force development was 27% in the patellar tendon autograft group and 48% in the ACL-H group, which were both lower than the 97% LSI of the controls (P < 0.001). After 2 mos, only in the ACL-H group, the LSI of both vertical peak force and rate of force development reached 88% and 80%, respectively, thus approaching the 96% and 92% LSI of the controls. CONCLUSIONS: Sit-to-stand is effective for measuring functional deficits as early as 1 mo after ACL reconstruction. After 2 mos from surgery, the ACL-H group but not the patellar tendon autograft group approached the LSI of the control group, which may be attributed to differences in the graft.

The effect of stance control orthoses on gait characteristics and energy expenditure in knee-ankle-foot orthosis users.

Stance Control knee-ankle foot orthoses (SCO) differ from their traditional locked knee counterparts by allowing free knee flexion during swing while providing stability during stance. It is widely accepted that free knee flexion during swing normalizes gait and therefore improves walking speed and reduces the energy requirements of walking. Limited research has been carried out to evaluate the benefits of SCOs when compared to locked knee-ankle foot orthoses (KAFOs). The purpose of this study was to evaluate the effectiveness of SCOs used for patients with lower limb pathology. Energy expenditure and walking velocity were measured in 10 subjects using an orthosis incorporating a Horton Stance Control knee joint. A GAITRite walkway was used to measure temporospatial gait characteristics. A Cosmed K4b2 portable metabolic system was used to measure energy expenditure and heart rate during walking. Two conditions were tested: Walking with stance control active (stance control) and walking with the knee joint locked. Ten subjects completed the GAITRite testing; nine subjects completed the Cosmed testing. Walking velocity was significantly increased in the stance control condition (p < 0.001). There was no difference in the energy cost of walking (p = 0.515) or physiological cost index (PCI) (p = 0.093) between conditions. This study supports previous evidence that stance control knee-ankle foot orthoses increase walking velocity compared to locked knee devices. Contrary to expectation, the stance control condition did not decrease energy expenditure during walking.

Evaluation of the lateral instability of the ankle by inversion simulation device and assessment of the rehabilitation program.

OBJECTIVES: To assess the correctibility of the muscle atrophy, proprioceptive loss, and slowing of the reflex arc around the ankle after ankle sprain with rehabilitation. METHODS: The study group consisted of 20 cases with chronic instability who had at least two episodes of ankle sprains (mean 20.6 years, range 16-32 years); control group consisted of 20 patients with same demographic characteristics but without instability. Isokinetic muscle strength measurements and proprioceptive evaluations were made using the Cybex device before and 1.5-month after rehabilitation period. Additionally, the inversion simulation device, which was developed together with the mechanical engineering department of our university, was correlated with the EMG device, and response periods of muscles to stimulation were measured. RESULTS: The proprioceptive loss present in all cases with ankle instability before treatment significantly improved after effective rehabilitation (p=0.001). It was detected that lengthened peroneal latent periods shortened with effective rehabilitation (p=0.001). Cross-interaction of rehabilitation was shown with the preservation of the difference between the pathologic and normal sides regarding proprioception and peroneal latent periods before and after treatment, without any difference between the control group and the pathologic sides. CONCLUSION: After ankle sprains, especially in patients with chronic instability, strengthening of the muscles around the ankle with well-planned proprioceptive exercises helps the patients return to normal living and sports activities, and prevents unnecessary surgery, especially in cases with functional instability.

Hypermobility and the hypermobility syndrome, part 2: assessment and management of hypermobility syndrome: illustrated via case studies.

Joint hypermobility syndrome (JHS) is a largely under-recognised and poorly understood multi-systemic hereditary connective tissue disorder which manifests in a variety of different clinical presentations. The assessment and management of patients with the syndrome is often complicated, requiring a comprehensive patient-centred approach and co-ordinated input from a range of medical, health and fitness professionals. The functional rehabilitation process is frequently lengthy, with education of the patient and family, sensitively prescribed and monitored physical therapy interventions and facilitation of lifestyle and behaviour modifications being the mainstay of the plan. Two typical but very different case studies are presented, each illustrating key aspects of the assessment and highlighting the variety of management strategies and techniques required by therapists to facilitate successful outcomes.

Factors associated with physiotherapists' confidence during assessment of clinical cervical and lumbar spine instability.

BACKGROUND AND PURPOSE: Physiotherapists commonly encounter patients with complaints of vague, indistinguishable neck and back pain, such as clinical spine instability. Since confidence is a component of expert clinical practice, we were interested in measuring expert clinicians' confidence in diagnosing and assessing clinical spine instability. The aims of the present study were to factor out the common 'identifiers' associated with physiotherapists' objective, physical diagnosis and assessment of clinical spine instability, and to determine the association of reported diagnostic confidence to these identifiers. METHOD: The study used data from a Delphi instrument for the factor analysis and a survey of APTA Board-certified orthopaedic specialists for report of confidence. Using an ologit regression analysis, the identifier themes and clinical background characteristics were associated with confidence in diagnosis of clinical spine instability. RESULTS: Only clinical cervical spine instability obtained significant findings. The identifier 'observable or palpable abnormalities of motion during movement assessment in clinical practice' was positively associated with reported confidence in diagnosis, as was the influence of manual therapy background models: Cyriax, Maitland, McKenzie, NAIOMPT, Osteopathic, Paris and other. Male gender yielded negative association with reported confidence. No factors were associated with reported lumbar confidence. CONCLUSIONS: Multiple backgrounds of physiotherapists demonstrate confidence in detecting clinical spine instability using observable or palpable methods to detect abnormal movements.

Functional anterior cruciate ligament bracing: a survey of current brace prescription patterns.

This study surveyed orthopedic surgeons regarding anterior cruciate ligament (ACL) bracing practices. Surveys were mailed to 1194 members of the American Orthopaedic Society for Sports Medicine. The return rate was 24% (n = 287). Descriptive analysis revealed that 13% of physicians never brace ACL-reconstructed patients, whereas only 3% never brace ACL-deficient patients. Physicians prescribe off-the-shelf braces more frequently for ACL-deficient patients than ACL-reconstructed patients (P = .000). Half reported bracing less frequently than 5 years ago. The wide range of responses reflects the lack of scientific basis for bracing decisions. Continued research efforts are encouraged. In the interim, the physician's clinical judgment provides the basis for bracing decisions.

Clinical assessment and rehabilitation of shoulder and knee sensorimotor control.

The orthopedic surgeon must perform a thorough evaluation of an unstable joint to derive the accurate diagnosis. One component of this examination is evaluation of the sensorimotor system. This article provides an overview of techniques and methodology used to assess the sensorimotor system. Rehabilitation concepts are presented to assist the physician during patient consultation following injury or surgery.

Measurement of scapular asymetry and assessment of shoulder dysfunction using the Lateral Scapular Slide Test: a reliability and validity study.

BACKGROUND AND PURPOSE: The Lateral Scapular Slide Test (LSST) is used to determine scapular position with the arm abducted 0, 45, and 90 degrees in the coronal plane. Assessment of scapular position is based on the derived difference measurement of bilateral scapular distances. The purpose of this study was to assess the reliability of measurements obtained using the LSST and whether they could be used to identify people with and without shoulder impairments. Subjects. Forty-six subjects ranging in age from 18 to 65 years (X=30.0, SD=11.1) participated in this study. One group consisted of 20 subjects being treated for shoulder impairments, and one group consisted of 26 subjects without shoulder impairments. METHODS: Two measurements in each test position were obtained bilaterally. From the bilateral measurements, we derived the difference measurement. Intraclass correlation coefficients (ICC [1,1]) and the standard error of measurement (SEM) were calculated for intrarater and interrater reliability of the difference in side-to-side measures of scapular distance. Sensitivity and specificity of the LSST for classifying subjects with and without shoulder impairments were also determined. RESULTS: The ICCs for intrarater reliability were .75, .77, and .80 and .52, .66, and .62, respectively, for subjects without and with shoulder impairments in 0, 45, and 90 degrees of abduction. The ICCs for interrater reliability were .67, .43, and .74 and .79, .45, and .57, respectively, for subjects without and with shoulder impairments in 0,45 and 90 degrees of abduction. The SEMs ranged from 0.57 to 0.86 cm for intrarater reliability and from 0.79 to 1.20 cm for interrater reliability. Using the criterion of greater than 1.0 cm difference, sensitivity and specificity were 35% and 48%, 41% and 54%, and 43% and 56%, respectively, for 0, 45, and 90 degrees of abduction. Sensitivity and specificity based on the criterion of greater than 1.5 cm difference were 28% and 53%, 50% and 58%, and 34% and 52%, respectively, for the 3 scapular positions. CONCLUSION AND DISCUSSION: Our results suggest that measurements of scapular positioning based on the difference in side-to-side scapular distance measures are not reliable. Furthermore, the results suggest that sensitivity and specificity of the LSST measurements are poor and that the LSST should not be used to identify people with and without shoulder dysfunction.

The effects of the number and frequency of physical therapy treatments on selected outcomes of treatment in patients with anterior cruciate ligament reconstruction.

Health care reform will quite possibly change the delivery of physical therapy by demanding physical therapists to be more accountable for providing appropriate, yet cost-effective treatment. The purpose of this study was to retrospectively compare the results after anterior cruciate ligament (ACL) reconstruction between two groups of patients with different numbers and frequencies of physical therapy visits postoperatively. Two random samples of 100 patients from a total of 1,345 patients identified as undergoing ACL reconstruction from 1990 through 1993 were included. Group A patients attended physical therapy regularly and participated in a home exercise program, while patients in Group B attended limited physical therapy visits and also performed a prescribed home exercise program. Both groups followed the same postoperative rehabilitation program for early range of motion, early weight bearing, and muscle control. The outcome variables measured 1, 6, and 12 months postoperatively included the number of structured visits to physical therapy, range of motion, isokinetic strength testing, and subjective rating. Group A averaged 20 visits in the first 6 months while Group B averaged seven visits. The results revealed no significant difference for flexion, isokinetic strength, or subjective rating. There was a significant difference for hyperextension (Group A, 2 degrees; Group B, 6 degrees). The results of this investigation indicated that by following a structured physical therapy program postoperatively, it is possible for patients to achieve a successful outcome with a limited number of routine physical therapy visits.
