Thoracic hyperkyphosis may adversely influence physical function in older adults, but the literature is mixed and confounded by possible sex differences. This systematic review and meta-analysis aimed to examine the association between hyperkyphosis and physical function in older females. Scopus, ISI Web of Science, Cochrane Library, PubMed, CINAHL, and PEDro databases were searched through 2021 for studies that included measures of thoracic hyperkyphosis and physical function with extractable data for women older than 60 years. Studies were excluded if they were qualitative, case reports, case series, ecological studies, reviews, or were not published in English. The study quality and risk of bias were assessed using checklists from the National Heart, Lung, and Blood Institute. Data were synthesized using Cohen's d effect size and 95% confidence interval (CI), and random-effects models were used for the meta-analyses. Three cohort and 22 cross-sectional studies of fair to good quality met the inclusion criteria. Eight studies reporting single-group data showed a moderate association between greater kyphosis angles and lower physical function ( d = -0.57; 95% CI -0.73, -0.40). Fourteen studies reporting 2-group data showed a large negative effect on physical function for groups with greater kyphosis angles ( d = -1.16; 95% CI -1.53, -0.78). Three studies that reported multivariate data also tended to show negative associations between physical function and hyperkyphosis. Limitations include a relative lack of causal evidence; confirming causation requires additional longitudinal studies. Studies have assessed various physical function categories, including strength, gait, and balance. Future studies could determine the categories of function most affected so that preventive interventions could target hyperkyphosis appropriately. Hyperkyphosis was associated with lower physical function in older women. Three cohort studies suggest that greater kyphosis angles may predict greater loss of physical function over time. These results imply that therapies that help to minimize hyperkyphosis may help preserve function in older women.

Surgical reconstruction of the anterior cruciate ligament (ACL) and subsequent physical therapy can help athletes return to competition; however, re-injury rates remain disproportionately high due, in part, to lingering biomechanical and neurological factors that are not fully addressed during rehabilitation. Prior reports indicate that individuals exhibit altered electrical activity in both brain and muscle after ACL reconstruction (ACLR). In this investigation, we aimed to extend existing approaches by introducing a novel non-linear analysis of corticomuscular dynamics, which does not assume oscillatory coupling between brain and muscle: Corticomuscular cross-recurrence analysis (CM-cRQA). Our findings indicate that corticomuscular dynamics vary significantly between involved (injured) and uninvolved legs of participants with ACLR during voluntary isometric contractions between the brain and both the vastus medialis and lateralis. This finding points to a potential lingering neural deficit underlying re-injury for athletes after surgical reconstruction, namely the dynamical structure of neuromuscular (brain to quad muscle) coordination, which is significantly asymmetric, between limbs, in those who have ACLR.

Background and Purpose. Growing evidence supporting the effectiveness of pediatric experiential learning (EL) in physical therapist education programs suggests that EL can aid in the development of students' clinical reasoning (CR) and self-efficacy (SE). Previous studies indicate that pediatric EL provides students with structured learning opportunities that may lead to meaningful gains in psychomotor skills, self-confidence, communication, and CR. Whether gains can be achieved during a pediatric intensive course rather than a semester-long course is unknown. The purpose of this research was to evaluate the change in perceived CR and SE experienced by physical therapist students who completed a high-dose (at least 15 hours) EL pediatric-intensive (1 week). Case Description. Second-year physical therapist students (n = 18) enrolled in the Advanced Pediatric Elective Intensive completed the Self-Assessment of Clinical Reflection and Reasoning (SACRR) and the Physical Therapy Self-Efficacy Scale (PTSE) on the first and last day of the course. Outcomes. A paired-samples t test revealed a statistically significant increase in SACRR scores from pre-test (M = 91.29, SD = 8.04) to post-test (M = 102.88, SD = 7.06), t (16) = 7.30, P < .001, as well as PTSE scores from pre-test (M = 13.44, SD = 2.64) to post-test (M = 19.00, SD = 2.06), t (17) = 9.70, P < .001. The results of this research suggest that active teaching methods, such as EL, may contribute to improvements in physical therapist students' perceived CR and SE. Discussion and Conclusion. Educators could consider a week-long EL intensive as a feasible and effective option to increase physical therapist students' perceived CR and SE related to pediatric physical therapy practice.

ObjectiveThe purpose of this case is to describe an outpatient treatment course using previously published systemic manual therapy protocol to treat a 65-year-old patient who, after prolonged COVID-related intubation, presented with polyneuropathy, organ failure and other residuals. DesignA single-subject case study. MethodsReview of clinical records and follow-up interview. ResultsThe patient identified problem scale (PIP) had improved from a high score of 52 to 11; QUICKDASH score improved from 68 to 16. All individual problems had either resolved or remained at a minimal level and the patient had generally returned to his prior level of function including return to work. Discussion and conclusionIt appears that Despite factors such as age, length of ICU stay, length of symptoms before initiation of physical therapy, and complicated hospital stay including multiple organ failure, after receiving physical therapy consists of the systemic manual therapy protocols, the patient rapidly improved during the outpatient episode.

Despite the extensive evidence supporting physical activity (PA) for managing chronic low back pain (CLBP), little is known about PA prescription by physical therapists treating patients with CLBP. 1) Explore how PA prescriptions provided by outpatient physical therapists treating patients with CLBP align with PA guidelines. 2) Examine the barriers and facilitators of PA prescription among physical therapists working with patients with CLBP. We conducted a qualitative study with outpatient physical therapists who treat CLBP. Semi-structured interviews provided an understanding of physical therapist experience with PA prescription among patients with CLBP. The interviews were transcribed, coded, and analyzed thematically. The 18 participants had an average of 13.4 (6.4) years of clinical experience in outpatient physical therapy. Thematic analysis revealed: 1) Physical therapists' articulate knowledge of PA guidelines and importance of physical activity; 2) Patient factors take priority over the PA guidelines for people with CLBP; and 3) The importance of building and maintaining a strong patient-therapist relationship influences physical therapist prescription of PA for patients with CLBP. When providing PA recommendations for patients with CLBP, general movement recommendations are emphasized in place of explicit PA prescriptions. Our findings highlight factors for consideration when prescribing movement and PA for patients with CLBP.

Humans and mice with mutations in COL4A1 and COL4A2 manifest hallmarks of cerebral small vessel disease (cSVD). Mice with a missense mutation in Col4a1 at amino acid 1344 (Col4a1+/G1344D) exhibit age-dependent intracerebral hemorrhages (ICHs) and brain lesions. Here, we report that this pathology was associated with the loss of myogenic vasoconstriction, an intrinsic vascular response essential for the autoregulation of cerebral blood flow. Electrophysiological analyses showed that the loss of myogenic constriction resulted from blunted pressure-induced smooth muscle cell (SMC) membrane depolarization. Furthermore, we found that dysregulation of membrane potential was associated with impaired Ca2+-dependent activation of large-conductance Ca2+-activated K+ (BK) and transient receptor potential melastatin 4 (TRPM4) cation channels linked to disruptions in sarcoplasmic reticulum (SR) Ca2+ signaling. Col4a1 mutations impair protein folding, which can cause SR stress. Treating Col4a1+/G1344D mice with 4-phenylbutyrate, a compound that promotes the trafficking of misfolded proteins and alleviates SR stress, restored SR Ca2+ signaling, maintained BK and TRPM4 channel activity, prevented loss of myogenic tone, and reduced ICHs. We conclude that alterations in SR Ca2+ handling that impair ion channel activity result in dysregulation of SMC membrane potential and loss of myogenic tone and contribute to age-related cSVD in Col4a1+/G1344D mice.

Delays in initiation of advanced therapies, which include biologics and targeted synthetic disease-modifying antirheumatic drugs, contribute to poor patient outcomes. The objective of this quality improvement project was to identify factors that lead to a delay in the initiation of advanced therapy and to perform plan-do-study-act cycles to decrease the time to start advanced therapy. A retrospective chart review identified factors involved in delay to start advanced therapy. The primary outcome of the study was the number of days to advanced therapy start as measured by the date of rheumatologist recommendation to the date advanced therapy was initiated by the patient. An Advanced Therapy Coordinator role was created to standardize the workflow, optimize communication, and ensure a safety checklist was instituted. A total of 125 patients were reviewed for the study with 18 excluded. Preintervention median wait time was 82.0 (IQR 46.0-80.5) days. Median wait time during the intervention improved to 49.5 (IQR 34.0-69.5) days (April 2021 to January 2022), with nonrandom variation post intervention. Nonrandom variation was also noted in the latter baseline data (March 2020 to March 2021). This study demonstrates improved wait time to advanced therapy initiation through the role of an Advanced Therapy Coordinator to facilitate communication pathways.

The Dystonia Medical Research Foundation organized an expert virtual workshop in March 2023 to review the evidence on non-motor symptoms across the spectrum of dystonia, discuss existing assessment methods, need for their harmonisation and roadmap to achieve this, and evaluate potential treatment approaches. Albeit the most investigated non-motor domains, experts highlighted the need to identify the most accurate screening procedure for depression and anxiety, clarify their mechanistic origin and quantify their response to already available therapies. Future exploration of sleep disruption in dystonia should include determining the accuracy and feasibility of wearable devices, understanding the contribution of psychotropic medication to its occurrence, and defining the interaction between maladaptive plasticity and abnormal sleep patterns. Despite recent advances in the assessment of pain in dystonia, more research is needed to elucidate the relative importance of different mechanisms called into play to explain this impactful sensory feature and the most appropriate treatments. Amongst the different non-motor features investigated in dystonia, cognitive dysfunction and fatigue require an in-depth observation to evaluate their functional impact, their clinical profile and assessment methods and, in the case of cognition, whether impairment represents a prodrome of dementia. Finally, experts identified the development and field validation of a self-rated screening tool encompassing the full spectrum of non-motor symptoms as the most urgent step towards incorporating the management of these features into routine clinical practice.

Resistance training with low loads in combination with blood flow restriction (BFR) facilitates increases in muscle size and strength comparable with high-intensity exercise. We investigated the effects of BFR on single motor unit discharge behavior throughout a sustained low-intensity isometric contraction. Ten healthy individuals attended two experimental sessions: one with, the other without, BFR. Motor unit discharge rates from the tibialis anterior (TA) were recorded with intramuscular fine-wire electrodes throughout the duration of a sustained fatigue task. Three 5-s dorsiflexion maximal voluntary contractions (MVC) were performed before and after the fatigue task. Each participant held a target force of 20% MVC until endurance limit. A significant decrease in motor unit discharge rate was observed in both the non-BFR condition (from 13.13 ± 0.87Hz to 11.95 ± 0.43Hz, P = 0.03) and the BFR condition (from 12.95 ± 0.71Hz to 10.9 ± 0.75Hz, P = 0.03). BFR resulted in significantly shorter endurance time and time-to-minimum discharge rates and greater end-stage motor unit variability. Thus, low-load BFR causes an immediate steep decline in motor unit discharge rate that is greater than during contractions performed without BFR. This shortened neuromuscular response of time-to-minimum discharge rate likely contributes to the rapid rate of neuromuscular fatigue observed during BFR.

Context Although interprofessional education (IPE) is not a new concept in health profession programs, the integration of this collaborative approach into athletic training education is still relatively new. Interprofessional education learning experiences can be embedded in a current course, presented in a stand-alone course, or integrated into service learning, simulation, or clinical education. Regardless of implementation strategy, IPE learning experiences should be adapted to each institution in response to program needs and resources available. Objective To describe the development of an IP course that includes 10 health profession programs. Background Although athletic training programs are required to implement IP collaborative practices, some institutions may experience challenges in developing strategies to meet this goal. Opportunities to engage in IPE initiatives may be present within your own college, institution, and community. Description We will describe the implementation of an IP course that included 10 health profession programs. The paper will outline the course design, course delivery, outcomes/data, and lessons learned along the way to support the continued advancement of IPE in athletic training programs. This course, through revisions, also included foundational understanding for concepts of cultural humility and the competence continuum along with strategies for respectful and effective team building in a diverse and IP environment. Clinical Advantage(s) Through this course, athletic training students are able to interact and collaborate with students from varied health profession programs, which leads to an increased level of rapport among students as well as discussions and integration of diversity, equity, and inclusion. The course also provides athletic training students with opportunities to educate future health professionals about athletic training. Conclusion(s) When contemplating implementing an IPE course, administrators should consider other health programming and students in their respective colleges, campuses, and communities. Other considerations for successful course development include administrative support and buy-in.
