Is There a Difference in Abdominal Wall Muscle Strength, Endurance, and Motor Control Following Bilateral DIEP and TRAM Flaps for Breast Reconstruction?

Background: Abdominal donor site complications in bilateral pedicled transverse rectus abdominis muscle (TRAM) have been a concern when compared with bilateral deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study aimed to assess the strength, endurance, and motor control in patients undergoing DIEP and TRAM flaps. Methods: A prospective, cohort study was performed at a single institution including patients who underwent pedicled TRAM and DIEP flap reconstruction after mastectomy from August 2017 to August 2018. Patients underwent pre- and postoperative testing involving rectus abdominis, prone plank, side bridge, and trunk flexor tests. Descriptive analyses and multivariate linear regressions were performed. Results: The final analysis included a total of 9 patients, 4 of whom underwent TRAM flap reconstruction while 5 underwent DIEP flap reconstruction. The tests were not statistically significant between the TRAM versus DIEP groups, including rectus abdominis mean time decrease (0.25 vs 0.60 sec, P = .51), prone plank time increase (1.38 vs 1.38 sec, P = .51), right side bridge time increase (7.54 sec vs 32.15 sec, P = 1.00), left side bridge time increase (2.14 vs 44.5 sec, P = .37), and trunk flexor time decrease (4.68 vs 1.68 sec, P = .44). Overall complications were similar between the 2 groups. Conclusions: No significant difference in abdominal donor site morbidity was found when comparing the 2 groups. This article provides a point of conversation with patients when discussing available reconstruction options.

Development of a Novel Evidence-Based Practice-Specific Competency for Doctor of Physical Therapy Students in Clinical Education: A Modified Delphi Approach.

INTRODUCTION: Evidence-based practice (EBP) results in high-quality care and decreases unwarranted variation in practice. REVIEW OF THE LITERATURE: Few performance criteria related to EBP are included in physical therapy clinical education (CE) performance measures, despite EBP requirements in Doctor of Physical Therapy education. The purpose of this study was to develop EBP-specific competencies that may be used for Doctor of Physical Therapy students for use throughout CE. SUBJECTS: Thirteen subject matter experts (SME) participated in this study. METHODS: Subject matter experts were asked to rank each core EBP competency, from a previously described framework, using a 3-point Likert scale, which included "Not Essential," "Essential," and "Not Sure." A consensus of 70% or greater for the "Essential" rating advanced the competency to the final Delphi round, whereas a consensus of 70% or greater for the "Not Essential" rating was required for competency elimination. Subject matter experts voted to either "Accept" or "Modify" the competencies that had reached the inclusion consensus threshold. All competencies that reached consensus for inclusion after all 3 rounds were included in the final EBP Domain of Competence. RESULTS: Consensus was achieved in round one for 38% (n = 26) of items. In round 2, a consensus was achieved for 20% (n = 8) of items. Of the items remaining after rounds 1 and 2, 6 overarching competencies were identified, and all remaining items served as descriptions and specifications in the final EBP Domain of Competence. DISCUSSION AND CONCLUSIONS: The 6 competencies developed from this study constitute the EBP Domain of Competence and may be used throughout CE to assess students' EBP competency in clinical practice.

Body Mass Index and Thoracic Expansion in Post-COVID Dyspnea: A Secondary Analysis.

Dyspnea secondary to lung impairment can persist following the acute phase of COVID-19. Thoracic expansion measurements have been used as a diagnostic tool to evaluate chest wall mobility, respiratory function, and the effects of respiratory muscle strength training. Changes in chest wall mobility may occur because of altered chest biomechanics in individuals with respiratory diseases and an elevated body mass index (BMI). The purpose of this secondary analysis was to evaluate whether BMI influences thoracic expansion or forced expiratory volume over 1 second (FEV1) in individuals with persistent dyspnea following COVID-19. This study assessed the relationship between BMI and thoracic expansion, pulmonary symptoms, and exercise capacity following a home-based pulmonary rehabilitation intervention. A secondary data analysis was conducted with a sample of 19 adults with persistent dyspnea following COVID-19 infection who participated in a 12-week, home-based pulmonary rehabilitation study. Participants received expiratory muscle strength training devices and were instructed to perform pulmonary rehabilitation exercises three times per week over the study period. Pulmonary function, pulmonary symptoms, exercise capacity, and BMI measurements were collected. For analysis, study participants were divided into obese (BMI > 30 kg/m2) or nonobese (BMI < 30 kg/m2) categories. Correlations using the change scores from baseline to 12 weeks between thoracic expansion, FEV1, pulmonary symptoms, and exercise capacity were assessed. In addition, the minimal detectable change (MDC) in thoracic expansion was explored. Thoracic expansion was significantly improved after 12 weeks of training (p = .012) in the nonobese group. There was a significant correlation between the change in walking distance and pulmonary symptoms (r = -.738, p < .001) and in thoracic expansion (r = .544, p = .020), and walking distance, when controlling for BMI, but no change in FEV1. Average MDC was 1.28 for inspiration and 0.91 for expiration. Measurements of thoracic expansion were significantly lower in post-COVID individuals with an increased BMI. Individuals with persistent dyspnea and a higher BMI may require additional measures to increase chest mobility or to detect pulmonary changes following COVID-19.

Assessing gait, balance, and muscle strength among breast cancer survivors with chemotherapy-induced peripheral neuropathy (CIPN): study protocol for a randomized controlled clinical trial.

BACKGROUND: Chemotherapy-induced peripheral neuropathy (CIPN) is a common and understudied consequence of taxane chemotherapy for breast cancer treatment. CIPN symptoms include numbness combined with tingling sensations, persistent shooting, stabbing, or burning pain even in the absence of painful stimuli, lower extremity muscle weakness, and impaired balance. CIPN symptoms often persist for a long time after completion of chemotherapy, causing significant loss of functional abilities and increased risk of falls. Persistent CIPN caused by taxanes represents a therapeutic challenge due to the limited treatment options. Resistance exercise has shown promising results; however, the effect of exercise on CIPN remains understudied. This study aims to assess the effects of exercise on gait, balance, and lower extremity muscle strength after a 16-week home-based exercise program compared to an educational attention control condition. METHODS: A sample of 312 women who completed taxane-based chemotherapy for breast cancer and have symptomatic neuropathy is recruited from a community-dwelling sample. Participants are randomized to either a 16-week Home-Based Physical Activity Intervention or an Educational Attention control group. The home-based intervention protocol consists of targeted lower extremity stretches, followed by 10 min each of gait/balance and 10 min of resistive training accessed by hyperlink or DVD. An Exercise Diary records quantitative exercise data. The gait assessment includes temporospatial parameters and lower extremity joint angles using APDM motion sensors. Participants' balance is assessed using the Sensory Organization Test (SOT) performed using a NeuroCom Balance Master. Isometric strength of hip, knee, and ankle flexor and extensor muscles is assessed using an isokinetic dynamometer, Biodex BX Advantage. In addition, we assess neuropathy symptoms using the FACT-Taxane Additional Concerns Subscale and nerve conduction velocity of the sural and peroneal nerve action potentials. Outcomes are assessed at baseline (prior to randomization) and 16 weeks. DISCUSSION: There are currently no evidence-based interventions that address the functional declines associated with CIPN. If successful, this program is simple and easy to implement in the standard of care for individuals with CIPN. Gait and balance training have the potential to reduce physical dysfunction associated with CIPN and reduce the burden of disease in cancer survivors.

Goal Attainment Scaling in Outpatient Physical Therapy for Chronic Low Back Pain: Protocol for a Mixed Methods Study.

BACKGROUND: Patient engagement in decisions regarding their health care may lead to improved outcomes and improved adherence to treatment plans. While there are several options for involving patients in their health care, goal setting is a readily accessible method for physical therapists to increase the involvement of patients in health care decisions. Physical therapy goals are often generated by health care providers based on subjective information or standardized, fixed-item, patient-reported outcome measures. However, these outcome measures may not fully reveal the activity and participation limitations of individual patients. Goal attainment scaling (GAS) is a patient-centered approach that allows patients to set meaningful goals. While GAS has been shown to be reliable, valid, and sensitive to change in various populations, there is limited evidence in the United States on utilizing GAS in physical therapy for patients with chronic low back pain (LBP). OBJECTIVE: The purpose of this paper is to describe the protocol for a study to (1) develop a way to apply GAS procedures for physical therapists treating patients with chronic LBP in the United States and (2) test the feasibility of applying GAS procedures for chronic LBP in an outpatient physical therapy setting. METHODS: This study used a mixed methods design with 2 phases: qualitative and quantitative. The qualitative phase of the study employed focus groups of patients with chronic LBP to identify an inventory of goals that were important and measurable. A series of prompts was developed from this inventory to assist physical therapists in collaboratively establishing goals with patients in a clinical setting. The quantitative phase of the study pilot-tested the inventory developed in the qualitative phase in patients with chronic LBP to determine feasibility, reliability, validity, and responsiveness. We also plan to compare how well GAS reveals change over time relative to traditional, fixed-item, patient-reported measures. RESULTS: Phase 1 data collection was completed in June 2020, while data collection for phase 2 was performed between March 2021 and December 2021. We anticipate that this study will demonstrate that GAS can be implemented successfully by outpatient physical therapists, and that it will demonstrate clinically important changes in patients with chronic LBP. CONCLUSIONS: GAS represents an opportunity for patient-centered care in the physical therapy management of chronic LBP. While GAS is not new, it has never been studied in real-world physical therapy for chronic LBP in a clinical setting. Due to unique time and productivity constraints, for GAS to be successfully implemented in this environment, we must demonstrate that clinicians can be trained efficiently and reliably, that GAS can be implemented in a clinical setting in under 15 minutes, and that GAS is able to detect clinically meaningful changes in patient outcomes.

Goal attainment scaling for patients with low back pain in rehabilitation: A systematic review.

BACKGROUND AND AIMS: Goal attainment scaling (GAS) has been widely applied to chronic conditions; however, only recently has it been used for patients with low back pain (LBP). The objectives of this systematic review were to (a) examine the characteristics and rigor of published studies of GAS in the rehabilitation of patients with LBP, (b) describe how GAS has been applied in patients with LBP, and (c) evaluate the responsiveness and validity of GAS as an outcome measure in patients with LBP. METHODS: A systematic search of the CINAHL, PubMed, and MEDLINE databases was performed (1968 and 1 September 2020) in addition to hand searching. Studies including GAS procedures in patients with LBP during rehabilitation were included in the review. Two authors independently selected studies for inclusion and determined levels of evidence using the Oxford Levels of Evidence and rated each study for quality using the Newcastle-Ottawa scale and reporting transparency using the STROBE statement checklist. RESULTS: Six Level IV and one Level III/IV study were included in this review (search produced 248 studies for review). These studies assessed GAS feasibility, validity, sensitivity, and association with other outcome measures in patients with LBP. Findings suggest that patients with LBP are able to identify and set individualized goals during GAS, while GAS may be more sensitive to change and may measure different aspects of the patient experience as compared with fixed-item patient-reported measures. Additionally, GAS may have a therapeutic effect while improving patient outcomes and may be associated with patient satisfaction. CONCLUSION: Based on this review, GAS shows promise as a feasible patient-centered measure that may be more responsive to change than traditional outcome measures. However, GAS has been inadequately developed and validated for use during rehabilitation in patients with LBP.

The effects of a laser-guided postural reeducation program on pain, neck active range of motion, and functional improvement in a 75-year-old patient with cervical dystonia.

Background and Purpose: Limited research exists regarding physical therapy management for patients with cervical dystonia (CD). The purpose of this case report is to describe the clinical management of a patient with CD using manual techniques, cervical traction, and laser-guided postural reeducation. Case Description: The patient was a 75-year-old female with CD, diagnosed 40 years prior, with a 10-year history of botulinum neurotoxin injections. She reported a 1-year history of worsening neck pain and cervical range of motion loss which was significantly affecting her ability to sleep and drive. The patient was seen for 12 visits over a 6-week period. Outcomes: Discharge scores indicated marked improvements in active range of motion, neck disability index, and the CDIP-58 questionnaire. Improvement in motor control as measured during the SenMorCor™ Laser Functional Error Assessment was demonstrated in the motions of "looking right" (53%) and up (48%). Discussion: This case report indicates that a physical therapy program consisting of a daily laser-guided home program for head postural reeducation in conjunction with classic physical therapy techniques may be an option for patients with CD; however, further research is needed prior to adoption of these techniques as standard of care for patients with CD.

Pilates-based exercise in the treatment of a patient with persistent low back pain following transforaminal lumbar interbody fusion.

Background: Low back pain (LBP) is the most commonly reported cause of disability in people under the age of 45 and is estimated to occur in 60-70% of the adult population in the industrialized world. This case report describes the use of Pilates-based exercise (PBE) in the physical therapy management of a patient with persistent chronic low back pain (CLBP) following transforaminal lumbar interbody fusion.Case Description: The patient was a 24-year-old female with a 7-year history of LBP presenting 17 months following surgery. The patient remained with constant LBP and right hip pain at 8/10 on the Numeric Pain Rating Scale (NPRS) after completing a course of physical therapy following the lumbar fusion.Outcomes: The PBE intervention lasted for 22 sessions during which the patient demonstrated complete resolution of right hip pain and remained with intermittent LBP (2/10 NPRS) at discharge. Minimally Clinically Important Difference levels for all self-reported outcome measure instruments were exceeded at discharge. The patient returned to work with lifting restrictions.Discussion: Patients following spine surgery are often excluded in studies of spine stabilization and PBE interventions. This case report describes the use of PBE in the treatment of a patient following spine fusion. Research to elucidate the impact of PBE on patients with CLBP is needed.

Electromyographic and kinetic analysis of two abdominal muscle performance tests.

BACKGROUND: In order to accurately assess the abdominal muscles, clinicians need valid clinical measures. The double leg lowering test (DLLT) and lower abdominal muscle progression (LAMP) are two common tests of abdominal muscle performance. The purposes of this study were to determine the relation between surface electromyographic (EMG) activity during the DLLT and LAMP levels; hip joint resultant moments and DLLT and LAMP levels; and the two measures of DLLT and LAMP. METHODS: Ten healthy participants were tested under both conditions. Surface EMG activity of the abdominal muscles was obtained, while pelvic movement was detected simultaneously. RESULTS: A moderate to strong association was found between rectus abdominus muscle activity and a moderate association with the external obliques with both test levels. For the internal oblique/transversus abdominus, a moderate and weak association was found with the DLLT and LAMP, respectively. A very strong association existed between the hip resultant joint moments (RJM) and the DLLT, while there was a weak correlation between hip RJM and the LAMP. No significant correlation was found between the DLLT and LAMP grades. CONCLUSIONS: This finding suggests that these tests may measure different qualities of muscle performance and provides preliminary support for their use. Further evaluation of these assessments with clinical populations is necessary.

Responsiveness of the double limb lowering test and lower abdominal muscle progression to core stabilization exercise programs in healthy adults: a pilot study.

Low back pain (LBP) is one of the most prevalent and expensive health care problems in the United States. Studies suggest that stabilization exercise may be effective in the management of people with LBP. To accurately assess the effect of stabilization programs on muscle performance, clinicians need an objective measure that is both valid and reliable. The purpose of this study was to determine whether the double limb lowering test (DLLT) and lower abdominal muscle progression (LAMP) can detect a change in abdominal muscle performance after stabilization exercises. Eleven healthy participants (4 men and 7 women) were randomly assigned to either a specific stabilization exercise (SSE) or general stabilization exercise (GSE) group and were evaluated by the DLLT and LAMP before, during, and at the end of 8 weeks of training. Subjects attended exercise sessions twice per week over 8 weeks. No significant difference in pretest performance existed between the 2 groups. No significant difference was detected with the DLLT for either the SSE or GSE over time or when groups were combined. The LAMP detected a significant difference for the combined groups and GSE but not SSE over time. These data indicate that the LAMP is sensitive to change after a spinal stabilization program, whereas the DLLT does not detect a change after these programs. Furthermore, the GSE was more effective in producing these changes. Additional testing of these assessments is necessary to further validate these tests and to identify specific populations for which these tests may be most appropriate.

Quality of systematic reviews on specific spinal stabilization exercise for chronic low back pain.

STUDY DESIGN: Systematic literature review. OBJECTIVE: To evaluate the quality of systematic reviews (SRs) on specific stabilization exercises for chronic low back pain (LBP). BACKGROUND: Multiple SRs regarding the effectiveness of lumbar stabilization exercises for people with chronic LBP have been published. As more SRs are published, the more it is recognized that, like other forms of research, methodological quality affects the validity of, and conclusions drawn from, the data. METHODS: A search of MEDLINE, CINAHL, and Embase was completed. Additionally, the PEDro database was screened and hand searching was completed. Included SRs had to contain randomized controlled trials examining a specific stabilization exercise program for the treatment of chronic LBP. Additionally, the assessed outcome measures had to include pain and/or disability measures. Literature reviews and clinical practice guidelines were excluded. Three reviewers independently assessed each SR for methodological quality. RESULTS: The search produced 665 SRs for review, of which 8 fulfilled the inclusion criteria. Consensus quality assessment scores ranged from 13/26 to 26/26, with an average of 20.7 points. Percent agreement and kappa values for individual criteria scores ranged from 50% to 92% and 0.25 to 0.85, respectively. Agreement was moderate to substantial across individual items, except for criterion 1. The intraclass correlation coefficient for overall score was 0.98 (95% confidence interval: 0.96, 0.99). CONCLUSION: This review of SRs identified several high-quality reviews that indicated some benefit of specific stabilization exercise programs for patients with nonspecific chronic LBP. LEVEL OF EVIDENCE: Therapy, level 1a.

Back pain among health care workers in Pennsylvania 2002-2006.

UNLABELLED: While back pain is common among health care workers in the United States, the epidemiology of back pain is unclear. OBJECTIVE: The purpose of this study was to estimate the incidence and trend of back pain from work-related injuries among health care workers. METHODS: Data from the Pennsylvania Work Injuries and Illnesses Reports from 2002 to 2006 were analyzed. RESULTS: Estimated back injuries account for 24.6% of all reported injuries in healthcare workers in Pennsylvania. From 2002 to 2006, there was a 22.5% increase in the incidence of reported back pain in this population. CONCLUSIONS: Due to a lack of detailed reports regarding the incidence of back pain among Pennsylvania healthcare workers, it is recommended that a survey of healthcare workers who perform patient handling be completed.

Clinical assessment of low-back-pain treatment outcomes in athletes.

PATIENT SCENARIO: A 21-year-old male rodeo athlete complains of acute low back pain (LBP) after a bareback event. The athlete wishes to compete in a rodeo event in 4 d. CLINICAL OUTCOMES ASSESSMENT: Given the questionable validity and reliability of traditional clinical examination techniques for LBP, a treatment subgroup classification system combined with clinical outcomes assessment provides greater insight into suitable clinical interventions and patient response to treatment. Four LBP treatment subgroups based on the patient's clinical presentation and symptoms have been established: manipulation, stabilization, specific exercise, and traction. Manipulation subgroup research has produced a valid clinical prediction rule (CPR). The Visual Analog Scale, Numeric Rating Scale (NRS), Oswestry Low Back Pain Disability Index (ODI), Roland Morris Disability Questionnaire, Short Form 36 (SF-36), and Global Rating of Change Scale are valid, reliable, and responsive outcomes instruments with established values for minimum clinically important difference (MCID). These instruments document important changes in disablement and health-related quality of life in patients with low back injury, as well as demonstrate treatment outcomes. CLINICAL DECISION MAKING: On examination the athlete presents with moderate pain and disability as measured by the NRS, ODI, and SF-36 and meets all 5 criteria for the manipulation subgroup, indicating a high likelihood of success with manipulative therapy when following the guidelines presented in the CPR. Expected outcomes values, based on MCID values, were met after 1 treatment. Preferred outcomes, based on physical activity requirements for sport, were met on day 4. CLINICAL BOTTOM LINE: LBP generators are difficult to establish using traditional clinical examination techniques. The combined use of clinical criteria, using an LBP subgroup system, and baseline outcomes measures should guide treatment. Benchmarks should be guided by established MCID values for each instrument.
