Examining online international health professions education: a mixed methods review of barriers, facilitators, and early outcomes☠.

BACKGROUND: Access to quality healthcare education across the world is disproportionate. This study explores the potential for Cardiovascular Perfusion education to be delivered online to reach international students. METHODS: Exploratory mixed methods were used to identify the barriers, facilitators, and early outcomes of online international health professions education. RESULTS: Qualitative analysis yielded four primary and nine subthemes. Multiple interventions were implemented in the planning of a novel online international Extracorporeal Science (ECS) program based on these themes. Quantitative data from the first semester of the new ECS program was collected along with data from the traditional entry-level program and historic data from previous entry-level cohorts. No significant correlations or differences were found between students. Student satisfaction surveys were determined to be equivalent for each group. Mixed data analysis revealed exceptional student satisfaction in areas where qualitative feedback was incorporated into the program design. CONCLUSIONS: Online international education may be a viable option in the health professions. Barriers and facilitators to this mode of education were identified and utilized in designing one such program. Early outcomes from the novel ECS program reveal that student performance and satisfaction are equivalent to those of a traditional in-person training program.

Physical Therapy versus Glucocorticoid Injection for Osteoarthritis of the Knee.

BACKGROUND: Both physical therapy and intraarticular injections of glucocorticoids have been shown to confer clinical benefit with respect to osteoarthritis of the knee. Whether the short-term and long-term effectiveness for relieving pain and improving physical function differ between these two therapies is uncertain. METHODS: We conducted a randomized trial to compare physical therapy with glucocorticoid injection in the primary care setting in the U.S. Military Health System. Patients with osteoarthritis in one or both knees were randomly assigned in a 1:1 ratio to receive a glucocorticoid injection or to undergo physical therapy. The primary outcome was the total score on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at 1 year (scores range from 0 to 240, with higher scores indicating worse pain, function, and stiffness). The secondary outcomes were the time needed to complete the Alternate Step Test, the time needed to complete the Timed Up and Go test, and the score on the Global Rating of Change scale, all assessed at 1 year. RESULTS: We enrolled 156 patients with a mean age of 56 years; 78 patients were assigned to each group. Baseline characteristics, including severity of pain and level of disability, were similar in the two groups. The mean (±SD) baseline WOMAC scores were 108.8±47.1 in the glucocorticoid injection group and 107.1±42.4 in the physical therapy group. At 1 year, the mean scores were 55.8±53.8 and 37.0±30.7, respectively (mean between-group difference, 18.8 points; 95% confidence interval, 5.0 to 32.6), a finding favoring physical therapy. Changes in secondary outcomes were in the same direction as those of the primary outcome. One patient fainted while receiving a glucocorticoid injection. CONCLUSIONS: Patients with osteoarthritis of the knee who underwent physical therapy had less pain and functional disability at 1 year than patients who received an intraarticular glucocorticoid injection.

Are Exercise and Physical Therapy Common Forms of Conservative Management in the Year Before Lumbar Spine Surgery?

OBJECTIVE: To quantify and compare utilization of opioids, exercise therapy, and physical therapy in the year before spine surgery. DESIGN: A retrospective cohort of surgical and claims data. SETTING: Beneficiaries of the Military Health System seen at Brooke Army Medical Center PARTICIPANTS: Patients (N=411) undergoing surgery between January 1, 2014, and December 31, 2015, identified retrospectively through the Surgical Scheduling System (S3) based on procedure type (fusion, laminectomy, arthroplasty, vertebroplasty, and diskectomy). INTERVENTIONS: Elective lumbar spine surgery. MAIN OUTCOME MEASURES: Health care utilization variables present during the full 12 months before surgery, which included physical therapy services and visits for exercise therapy or manual therapy procedures and opioid prescriptions. RESULTS: The mean age of participants was 44.8±11.7 years and 32.4% were female. In the year before surgery, 143 (34.8%) patients had a physical therapy plan of care, 140 (34.1%) had at least 1 visit that included exercise therapy, and only 60 (14.6%) had a minimum of 6 exercise therapy visits. However, 347 (84.4%) patients received at least 1 opioid prescription fill (mean of 6.1 unique fills). CONCLUSIONS: Before elective lumbar spine surgery, opioid prescriptions were common but physical therapy services and exercise therapy utilization occurred infrequently.

Manual physical therapy combined with high-intensity functional rehabilitation for severe lower extremity musculoskeletal injuries: a case series.

OBJECTIVES: Severe lower extremity trauma accounts for large healthcare costs and often results in elective amputation and poor long-term outcomes. The purpose of this case series is to describe an orthopedic manual physical therapy (OMPT) approach combined with a return to run (RTR) clinical pathway consisting of high-intensity functional rehabilitation with a custom energy-storing orthosis. METHODS: Three consecutive male patients, aged 21-23 years, with severe lower extremity musculoskeletal injuries were treated with a combined intervention that included a mean (SD) of 12 (2·1) OMPT sessions and 24 (8·7) functional rehabilitation sessions over a mean of 6 weeks (1·0). Additional training with a custom energy-storing orthosis consisted of a mean of 15 (1·2) additional sessions over 4 weeks. Patient self-report outcome measures and a variety of physical performance tests captured change in function. RESULTS: Baseline lower extremity functional scale (LEFS) and foot and ankle ability measure activities of daily living subscale (FAAM-ADL) scores indicated severe disability. All patients exceeded the minimal clinically important difference (MCID) in at least one self-report outcome or physical performance test without a brace. Two of three patients exceeded the MCID for at least two physical performance tests after training with and utilizing a custom energy-storing orthosis. DISCUSSION: Clinically meaningful changes in self-reported function or physical performance were observed in all patients. A multi-modal approach, including manual therapy and functional exercise, may address the entire spectrum of impairments in patients with severe lower extremity trauma, resulting in improvements in both braced and un-braced function.

Assessment of Surgical Complications Strengthen the Relationship Between Spine Surgery Procedure Intensity and Chronic Opioid use After Surgery.

STUDY DESIGN: Prospective cohort using routinely-collected health data. OBJECTIVE: To compare opioid use based on surgery intensity (low or high). SUMMARY OF BACKGROUND DATA: Many factors influence an individual's experience of pain. The extent to which post-surgical opioid use is influenced by the severity of spine surgery is unknown. METHODS: The participants were individuals undergoing spine surgery in a large military hospital. Procedures were categorized as low-intensity (e.g., microdiscectomy and laminectomy) and high-intensity (e.g., fusion and arthroplasty). The Surgical Scheduling System and Military Health System Data Repository were queried for healthcare utilization the 1 year before and after surgery. We compared opioid use after surgery between groups, adjusting for prior opioid use and surgical complications. RESULTS: 342 individuals met the inclusion criteria, mean age 45.4 years (SD 10.9), 33.0% female. Of these, 221(64.6%) underwent a low-intensity procedure and 121(35.4%) underwent a high-intensity procedure. Mean postoperative opioid prescription fills were greater in the high- versus low-intensity group (9.0 vs. 5.7;P<0.001), as were the mean total days' supply (158.9 vs. 81.8;P<0.001). Median morphine milligram equivalents were not significantly different (MME; 40.2 vs. 42.7;P=0.287). 26.3% of the cohort were chronic opioid users after surgery. Adjusted rates of long-term opioid use were not different between groups when only accounting for prior opioid use, but significantly higher for the high-intensity group when adjusting for surgical complications (OR=2.08;95CI 1.09,3.97). 52.5% of the entire cohort was still filling opioid prescriptions after six months. CONCLUSION: Higher-intensity procedures were associated with greater postoperative opioid use than lower-intensity procedures. Chronic opioid use was not significantly different between surgical intensity groups when considering only prior opioid use. Chronic opioid use was significantly higher among higher intensity procedures when accounting for surgical complications. The prresence of surgical complications is a stronger predictor of post-surgical long-term opioid use in high intensity surgeries than history of opioid use alone.

Joint mobilization forces and therapist reliability in subjects with knee osteoarthritis.

OBJECTIVES: This study determined biomechanical force parameters and reliability among clinicians performing knee joint mobilizations. METHODS: Sixteen subjects with knee osteoarthritis and six therapists participated in the study. Forces were recorded using a capacitive-based pressure mat for three techniques at two grades of mobilization, each with two trials of 15 seconds. Dosage (force-time integral), amplitude, and frequency were also calculated. Analysis of variance was used to analyze grade differences, intraclass correlation coefficients determined reliability, and correlations assessed force associations with subject and rater variables. RESULTS: Grade IV mobilizations produced higher mean forces (P<0.001) and higher dosage (P<0.001), while grade III produced higher maximum forces (P = 0.001). Grade III forces (Newtons) by technique (mean, maximum) were: extension 48, 81; flexion 41, 68; and medial glide 21, 34. Grade IV forces (Newtons) by technique (mean, maximum) were: extension 58, 78; flexion 44, 60; and medial glide 22, 30. Frequency (Hertz) ranged between 0.9-1.1 (grade III) and 1.4-1.6 (grade IV). Intra-clinician reliability was excellent (>0.90). Inter-clinician reliability was moderate for force and dosage, and poor for amplitude and frequency. DISCUSSION: Force measurements were consistent with previously reported ranges and clinical constructs. Grade III and grade IV mobilizations can be distinguished from each other with differences for force and frequency being small, and dosage and amplitude being large. Intra-clinician reliability was excellent for all biomechanical parameters and inter-clinician reliability for dosage, the main variable of clinical interest, was moderate. This study quantified the applied forces among multiple clinicians, which may help determine optimal dosage and standardize care.

Well-tolerated strategies for managing knee osteoarthritis: a manual physical therapist approach to activity, exercise, and advice.

The orthopedic manual physical therapist approach to knee osteoarthritis (OA) is an effective, well-tolerated, and comprehensive strategy that provides a spectrum of intervention measures, which include guidance on activity selection, as well as selection of manual treatment and exercises to systematically address impairments and increase strength and movement in the knee and other related body regions. This approach integrates manually applied treatment while reinforcing exercise and functional activities that are tailored in scope and dose to each patient. Concepts used in the careful design of this exercise program include emphasizing minimal dosing, avoiding exacerbation, using exercises with multiple effects, effective functional positioning, emphasizing the importance of mid-range movements and end-range challenges, and strategic timing of exercises. Focusing on motion and strength gains through range of motion, along with functional or reinforcing activities, such as walking or biking to maintain motion and strength gains, are keys to long-term success. The overarching theme is that well-tolerated strategies using manual treatment, exercise, and activity require deliberate design and targeting of the most common impairments and functional limitations seen in the knee OA population and, more importantly, tailoring to the individual patient.

Short- and long-term clinical outcomes following a standardized protocol of orthopedic manual physical therapy and exercise in individuals with osteoarthritis of the hip: a case series.

OBJECTIVES: Describe short- and long-term outcomes observed in individuals with hip osteoarthritis (OA) treated with a pre-selected, standardized set of best-evidence manual therapy and therapeutic exercise interventions. METHODS: Fifteen consecutive subjects (9 males, 6 females; mean age: 52±7.5 years) with unilateral hip OA received an identical protocol of manual therapy and therapeutic exercise interventions. Subjects attended 10 treatment sessions over an 8-week period for manual therapy interventions and performed the therapeutic exercise as a home program. RESULTS: Baseline to 8-week follow-up outcomes were as follows: Harris Hip Scale (HHS) scores improved from 60.3(±10.4) to 80.7(±10.5), Numerical Pain Rating Scale (NPRS) scores improved from 4.3(±1.9) to 2.0(±1.9), hip flexion range of motion (ROM) improved from 99 degrees (±10.6) to 127 degrees (±6.3) and hip internal rotation ROM improved from 19 degrees (±9.1) to 31 degrees (±11.5). Improvements in HHS, NPRS, and hip ROM measures reached statistical significance (P<0.05) at 8-weeks and remained significant at the 29-week follow-up. Mean changes in NPRS and HHS scores exceeded the minimal clinically important difference (MCID) at 8-weeks and for the HHS scores alone at 29 weeks. The 8 and 29 week mean Global Rating of Change scores were 5.1(±1.4) and 2.1(±4.2), respectively. Improved outcomes observed following a pre-selected, standardized treatment protocol were similar to those observed in previous studies involving impairment-based manual therapy and therapeutic exercise for hip OA. Future studies might directly compare the two approaches.

Engaging Education About Risks of Opioid Use With Patients Before Elective Surgery of the Lower Extremity Did Not Reduce Postoperative Opioid Utilization: A Randomized Controlled Trial.

INTRODUCTION: After elective orthopaedic surgery, many individuals go on to become long-term opioid users. Mitigating this risk has become a priority for surgeons, other members of the medical care team, and healthcare systems. The purpose of this study was to compare opioid utilization after lower extremity orthopaedic surgery between patients who received an interactive video education session highlighting the risks of opioid use and those who did not. METHODS: Patients undergoing elective surgery of the lower extremity in the orthopaedic clinic at the Brooke Army Medical Center between July 2015 and February 2017 were recruited at their preoperative appointment and randomized in a 1:1 ratio to receive a one-time interactive opioid education session or usual care education. Unique days' supply of opioids and unique prescriptions were compared using a generalized linear model. Individuals were also grouped by whether they had become long-term opioid users after surgery, and frequencies within each intervention group were compared. RESULTS: There were 120 patients, 60 randomized to each group and followed for 1 year. There were no significant differences between opioid days' supply (mean diff = 8.33, 95% confidence interval -4.21 to 20.87) and unique prescriptions after surgery (mean diff = 0.45, 95% confidence interval -0.25 to 1.15). Most participants did not have any opioids past the initial 30 days after surgery, regardless of intervention (n = 77), and only three became long-term opioid users (one in usual care and two in interactive education). Sixteen in usual education and 18 in enhanced education filled at least one prescription in 6 months or later after the surgical procedure. CONCLUSION: Opioid use beyond 30 days of surgery was no different for participants who received enhanced education compared with usual education. Few became long-term opioid users after surgery (2.5%), although 28.3% were still filling opioid prescriptions 6 months after surgery.

Does Engaging Patients with Relevant Education About Long-Term Opioid Use Before Spine Surgery Affect Long-term Opioid Use? A Randomized Controlled Trial.

STUDY DESIGN: Parallel-arm randomized controlled trial. OBJECTIVE: To assess the effectiveness of an enhanced video education session highlighting risks of opioid utilization on longterm opioid utilization after spine surgery. SUMMARY OF BACKGROUND DATA: Long-term opioid use occurs in more than half of patients undergoing spine surgery and strategies to reduce this use are needed. METHODS: Patients undergoing spine surgery at Brooke Army Medical Center between July 2015 and February 2017 were recruited at their preoperative appointment, receiving the singlesession interactive video education or control at that same appointment. Opioid utilization was tracked for the full year after surgery from the Pharmacy Data Transaction Service of the Military Health System Data Repository. Self-reported pain also collected weekly for 1 and at 6months. RESULTS: A total of 120 participants (40 women, 33.3%) with a mean age of 45.9 ±â€Š10.6 years were randomized 1:1 to the enhanced education and usual care control (60 per group). In the year following surgery the cohort had a mean 5.1 (standard deviation [SD] 5.9) unique prescription fills, mean total days' supply was 88.3 (SD 134.9), and mean cumulative morphine milligrams equivalents per participant was 4193.0 (SD 12,187.9) within the year after surgery, with no significant differences in any opioid use measures between groups. Twelve individuals in the standard care group and 13 in the enhanced education group were classified with having long-term opioid utilization. CONCLUSION: The video education session did not influence opioid use after spine surgery compared to the usual care control. There was no significant difference in individuals classified as long-term opioid users after surgery based on the intervention group. Prior opioid use was a strong predictor of future opioid use in this cohort. Strategies to improve education engagement, understanding, and decision- making continue to be of high importance for mitigating risk of long-term opioid use after spine surgery.Level of Evidence: 1.

Hook of the hamate fracture.

The patient was a 44-year-old man who reported palmar/ulnar-sided right wrist pain after injuring his wrist while playing golf. Although pain and function were improved at 6 months following the injury with conservative treatment measures and golfing with a modified grip, the patient was still limited during golf. This prompted the ordering of additional wrist radiographs, which included a carpal tunnel view, that revealed a fracture at the base of the hook of the hamate. The patient was referred to an orthopaedic surgeon and underwent a hook of hamate excision, and at 12 weeks following surgery, he had returned to full golfing activities without limitations.

Medical screening and evacuation: cauda equina syndrome in a combat zone.

STUDY DESIGN: Resident's case problem. BACKGROUND: Cauda equina syndrome (CES) is a rare, potentially devastating, disorder and is considered a true neurologic emergency. CES often has a rapid clinical progression, making timely recognition and immediate surgical referral essential. DIAGNOSIS: A 32-year-old male presented to a medical aid station in Iraq with a history of 4 weeks of insidious onset and recent worsening of low back, left buttock, and posterior left thigh pain. He denied symptoms distal to the knee, paresthesias, saddle anesthesia, or bowel and bladder function changes. At the initial examination, the patient was neurologically intact throughout all lumbosacral levels with negative straight-leg raises. He also presented with severely limited lumbar flexion active range of motion, and reduction of symptoms occurred with repeated lumbar extension. At the follow-up visit, 10 days later, he reported a new, sudden onset of saddle anesthesia, constipation, and urinary hesitancy, with physical exam findings of right plantar flexion weakness, absent right ankle reflex, and decreased anal sphincter tone. No advanced medical imaging capabilities were available locally. Due to suspected CES, the patient was medically evacuated to a neurosurgeon and within 48 hours underwent an emergent L4-5 laminectomy/decompression. He returned to full military duty 18 weeks after surgery without back or lower extremity symptoms or neurological deficit. DISCUSSION: This case demonstrates the importance of continual medical screening for physical therapists throughout the patient management cycle. It further demonstrates the importance of immediate referral to surgical specialists when CES is suspected, as rapid intervention offers the best prognosis for recovery. LEVEL OF EVIDENCE: Differential diagnosis, level 4. J Orthop Sports Phys Ther 2009;39(7):541-549, Epub 24 February 2009. doi: 10.2519/jospt.2009.2999.

Effectiveness of translational manipulation under interscalene block for the treatment of adhesive capsulitis of the shoulder: A nonrandomized clinical trial.

Study Design: Nonrandomized controlled trial. Objective: To determine whether translational manipulation under anesthesia/local block (TMUA) adds to the benefit of mobilization and range of motion exercise for improving pain and functional status among patients with adhesive capsulitis of the shoulder (AC). Background: TMUA has been shown to improve pain and dysfunction in patients with AC. This intervention has not been directly compared to physical therapy treatment without TMUA in a prospective trial. Methods: Sixteen consecutive patients with a primary diagnosis of AC were divided into two groups. Patients in the first (TMUA) group received a session of translational manipulation under interscalene block, followed by six sessions of manipulation and exercise. Patients in the comparison group received seven sessions of manipulation and exercise. Outcome measures taken at baseline and 3, 6, 12 months and 4 years included Shoulder Pain and Disability Index (SPADI) scores. Four-year outcomes included percent of normal ratings, medication use, and activity limitations. Results: Both groups showed improved SPADI scores across all follow-up times compared to baseline. The TMUA group showed a greater improvement in SPADI scores than the comparison group at 3 weeks, with no significant differences in SPADI scores at other time points. However, at 4 years, significantly more subjects in the comparison group (5 of 8) had activity limitations versus subjects in the TMUA group (1 of 8). No subject experienced a complication from either intervention protocol. Conclusion: Physical therapy consisting of manual therapy and exercise provides benefit for patients with AC. Translational manipulation under local block may be a useful adjunct to manual therapy and exercise for patients with AC.

Effect of multilevel lumbar disc arthroplasty on the operative- and adjacent-level kinematics and intradiscal pressures: an in vitro human cadaveric assessment.

BACKGROUND CONTEXT: With lumbar arthroplasty gaining popularity, limited data are available highlighting changes in adjacent-level mechanics after multilevel procedures. PURPOSE: Compare operative- and adjacent-segment range of motion (ROM) and intradiscal pressures (IDPs) after two-level arthroplasty versus circumferential arthrodesis. STUDY DESIGN: Cadaveric biomechanical study. METHODS: Ten human cadaveric lumbar spines were used in this investigation. Biomechanical testing was performed according to a hybrid testing protocol using an unconstrained spine simulator under axial rotation (AR), flexion extension (FE), and lateral-bending (LB) loading. Specimens were tested in the following order: 1) Intact, 2) L3-L5 total disc replacement (TDR), 3) L3-L5 anterior interbody cages+pedicle screws. IDP was recorded at proximal and distal adjacent levels and normalized to controls (%intact). Full ROM was monitored at the operative and adjacent levels and reported in degrees. RESULTS: Kinematics assessment revealed L3-L5 ROM reduction after both reconstructions versus intact controls (p < .05). However, global quality of segmental motion distributed over L2-S1 was preserved in the arthroplasty group but was significantly altered after circumferential fixation. Furthermore, adjacent-level ROM was increased for the arthrodesis group under LB at both segments and during AR at L2-L3 relative to controls (p < .05). FE did not reveal any intergroup statistical differences. Nonetheless, after arthrodesis IDPs were increased proximally under all three loading modalities, whereas distally a significant IDP rise was noted during AR and LB (p < .05). No statistical differences in either biomechanical parameter were recorded at the adjacent levels between intact control and TDR groups. CONCLUSIONS: Our results indicate no significant adjacent-level biomechanical changes between arthroplasty and control groups. In contrast, significant alterations in ROM and IDP were recorded both proximally (ROM=LB & AR; IDP=AR, FE, LB) and distally (ROM=LB; IDP=AR & LB) after circumferential arthrodesis. Therefore, two-level lumbar arthroplasty maintains a more favorable biomechanical environment at the adjacent segments compared with the conventional transpedicular fixation technique. This, in turn, may have a positive effect on the rate of the transition syndrome postoperatively.

Characterization of lateral abdominal muscle thickness in persons with lower extremity amputations.

STUDY DESIGN: Retrospective review. OBJECTIVES: To describe bilateral thickness of the lateral abdominal muscles at baseline and during an abdominal drawing-in maneuver (ADIM) in individuals with unilateral transtibial (TTA) or transfemoral (TFA) amputations. BACKGROUND: Although side-to-side symmetry of lateral abdominal muscle thickness has been established in healthy individuals, the degree of symmetry in those with unilateral lower extremity amputations remains unknown. Differences in lateral abdominal muscle thickness may exist based on prior findings of asymmetry and differences measured based on level of amputation in both the size and function of the iliopsoas and back extensor muscles. METHODS AND MEASURES: Seventy patients (69 males, 1 female) with traumatic unilateral lower extremity amputations (TTA, n = 39; TFA, n = 31) received a rehabilitative ultrasound imaging examination. Absolute thickness of the transversus abdominis (TrA) and the external and internal oblique muscles combined (EO+IO) were assessed bilaterally at baseline and during the ADIM. Symmetry was assessed using relative muscle thickness values at baseline. Percent increase in muscle thickness during the ADIM was used to investigate muscle function. Separate 2-by-2 mixed-model ANOVAs were used to compare both within-group (side of amputation versus nonamputated side) and between-group (TTA versus TFA) differences for thickness and function of the TrA and the EO+IO muscles. RESULTS: On the side of the amputation, the relative baseline thickness of the EO+IO measurement was greater (P < .05), while the relative baseline thickness of the TrA muscle was smaller (P < .05). But the mean differences side to side were small (1.3%) and unlikely to be clinically significant. Further, there were no differences in baseline muscle thickness between groups for the TrA (P = .95) or the EO+IO (P = .94) muscles. For thickness measurements during the ADIM, the TrA showed no side-to-side (P = .74) or group (P = .07) differences. Similarly, no side-to-side (P = .60) or group (P = .09) differences were found in the EO+IO thickness during the ADIM. CONCLUSIONS: Despite the limitations of retrospective review, these findings provide an initial reference data set for future studies. Bilateral symmetry of the lateral abdominal wall muscle thicknesses at baseline and during the ADIM for those with unilateral lower extremity amputations is comparable to healthy individuals. Future studies should consider the potential influences of low back pain and gait training on symmetry of muscle thickness and muscle function based on level of amputation.

Improved activation of lumbar multifidus following spinal manipulation: a case report applying rehabilitative ultrasound imaging.

STUDY DESIGN: Case report. BACKGROUND: The use of spinal manipulation as a treatment to facilitate neuromuscular control of the paraspinal musculature is not well described in the literature. The use of rehabilitative ultrasound imaging (RUSI) may offer a convenient way to investigate and document possible changes occurring in the lumbar multifidus associated with manipulation intervention. CASE DESCRIPTION: The patient was a 33-year-old male with a 21-year history of low back pain and left posterior thigh pain who presented with lumbar hypomobility and met a previously published clinical prediction rule for spinal manipulation. During examination, the patient was asked to perform a prone upper extremity lifting task to assess activation in the lumbar multifidus during an automatic task. Through palpation the examiner noted a decreased contraction of the left multifidus between L4-S1 compared to the right. To explore this further, a decision was made to assess the multifidus with RUSI, which confirmed the activation deficit noted during palpation. A lumbar regional manipulation was performed with the intention of reducing spinal hypomobility and of assessing changes in multifidus activation. Imaging of the multifidus muscles at the L4-5 and L5-S1 levels were obtained premanipulation, immediately postmanipulation, and 1 day after manipulation. OUTCOMES: An increased ability to thicken the multifidus during a prone upper extremity lifting task was noted immediately and 1 day after manipulation. Average percent change in thickness at the L4-5 and L5-S1 levels with the prone arm lift was 3.6% premanipulation, 17.2% immediately postmanipulation, and 20.6% approximately 24 hours postmanipulation. Improvements in the thickening of the multifidus muscle during the upper extremity lifting task were greater than 3 standard errors of the measurement. Other changes included immediate palpable improvement in the contraction of the multifidus during the upper extremity lifting task, along with the patient report of increased ease of lifting. DISCUSSION: In this case report we quantified the short-term influence of spinal manipulation on multifidus muscular activation using RUSI. No cause-and-effect claims can be made; however, the results provide preliminary evidence to suggest that spinal manipulation may influence multifidus muscle function. RUSI offers a convenient way to investigate and document these changes.

Rehabilitative ultrasound imaging of the abdominal muscles.

Rehabilitative ultrasound imaging (RUSI) of the abdominal muscles is increasingly being used in the management of conditions involving musculoskeletal dysfunctions associated with the abdominal muscles, including certain types of low back and pelvic pain. This commentary provides an overview of current concepts and evidence related to RUSI of the abdominal musculature, including issues addressing the potential role of ultrasound imaging in the assessment and training of these muscles. Both quantitative and qualitative aspects associated with clinical and research applications are considered, as are the possible limitations related to the interpretation of measurements made with RUSI. Research to date has utilized a range of methodological approaches, including different transducer placements and imaging techniques. The pros and cons of the various methods are discussed, and guidelines for future investigations are presented. Potential implications and opportunities for clinical use of RUSI to enhance evidence-based practice are outlined, as are suggestions for future research to further clarify the possible role of RUSI in the evaluation and treatment of abdominal muscular morphology and function.

Normative values for the unipedal stance test with eyes open and closed.

PURPOSE: Limited normative data are available for the unipedal stance test (UPST), making it difficult for clinicians to use it confidently to detect subtle balance impairments. The purpose of this study was to generate normative values for repeated trials of the UPST with eyes opened and eyes closed across age groups and gender. METHODS: This prospective, mixed-model design was set in a tertiary care medical center. Healthy subjects (n= 549), 18 years or older, performed the UPST with eyes open and closed. Mean and best of 3 UPST times for males and females of 6 age groups (18-39, 40-49, 50-59, 60-69, 70-79, and 80+) were documented and inter-rater reliability was tested. RESULTS: There was a significant age dependent decrease in UPST time during both conditions. Inter-rater reliability for the best of 3 trials was determined to be excellent with an intra-class correlation coefficient of 0.994 (95% confidence interval 0.989-0.996) for eyes open and 0.998 (95% confidence interval 0.996-0.999) for eyes closed. CONCLUSIONS: This study adds to the understanding of typical performance on the UPST. Performance is age-specific and not related to gender. Clinicians now have more extensive normative values to which individuals can be compared.

Effects of technique-focused training in conjunction with physical readiness training on Army physical fitness test performance.

The Army Physical Fitness Test (APFT) is a semiannual requirement. While conducting physical readiness training (PRT) is a requirement for all Soldiers, there is no requirement to train Soldiers on techniques that may help to optimize their performance on the APFT. A cohort of 34 officers that attended the Army Medical Department Basic Officer Leadership Course completed a technique-focused training program in conjunction with their required PRT program subsequent to failing one or more events on their initial APFT. The training consisted of a 30-minute video lesson and an individualized performance assessment completed by an Army physical therapist. Upon retest 10 days after the initial test, 27 (79.4%) participants passed the APFT with a mean improvement of 22.3 points on their overall APFT score. When evaluating change in performance by event based on failing the event initially, the observed improvement was an increase of over 9 push-ups, over 11 sit-ups, and nearly 2 minutes on the run event. The addition of a technique-focused training program to an existing PRT program can result in significant short-term improvement for those with substandard APFT performance.
