Background: The use of Pilates in various fields of sport sciences and rehabilitation is increasing; however, little is known about the muscle adaptations induced by this training method. Hypothesis: A standardized Pilates training program for beginners (9 months; 2 sessions of 55 minutes per week) will increase the muscle volume and reduce potential side-to-side asymmetries of the quadratus lumborum, iliopsoas, piriformis, and gluteus muscles (gluteus maximus, medius, and minimus). Study Design: Controlled laboratory study. Level of Evidence: Level 3. Method: A total of 12 inactive, healthy women (35.7 ± 5.4 years) without previous experience in Pilates were randomly selected to participate in a supervised Pilates program (36 weeks, twice weekly). Muscle volume (cm3) was determined using magnetic resonance imaging at the beginning and end of the intervention program. Side-to-side asymmetry was calculated as [(left – right volume) × 100/right volume]. Results: Small, nonsignificant ( P > 0.05) differences in the volume of the quadratus lumborum, iliopsoas, piriformis, and gluteus muscles were observed between pre– and post–Pilates program timepoints. Before and after Pilates, side-to-side asymmetry was less than 6% and nonsignificant in all muscles analyzed. Conclusion: Modern Pilates performed twice weekly for 9 months did not elicit substantial changes in the volume and degree of asymmetry of the selected lumbopelvic muscles in inactive women. Clinical Relevance: The benefits of Pilates in rehabilitation or training are likely elicited by neuromuscular rather than morphological adaptations. Pilates has no significant impact on muscle volume and does not alter side-to-side ratios in muscle volume (degree of asymmetry) of the lumbopelvic muscles.

This study reports a pre-experimental research on the impact of metacognitive instruction on EFL learners’ metacognitive awareness and their listening performance. To obtain the goal of the study, a group of 30 Iranian intermediate EFL learners, including 14 males and 16 females, were selected randomly. Their ages range from 20 to 24. The participants took part in 16 weeks’ intervention program based on metacognitive pedagogical sequence consisted of five stages. The metacognitive awareness listening questionnaire (MALQ), and a listening test were also used to find changes in metacognitive awareness and listening performance before and after the treatment. The results of comparing pre and posttests scores revealed that metacognitive instruction raised the learners’ metacognitive awareness and helped them improve their listening comprehension ability.

Paroxysmal Positional Vertigo

Background: Dizziness after concussion is primarily attributed to effects on the brain, but traumatic inner ear disorders can also contribute. Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder that can result from minor head trauma and can be easily diagnosed and rapidly treated in an office setting. The role of BPPV in pediatric postconcussive dizziness has not been well-studied. Purpose: To evaluate the prevalence and clinical features of BPPV in a group of pediatric patients with concussion and prolonged dizziness after concussion. Study Design: Case-control study. Level of Evidence: Level 3. Methods: Retrospective review of 102 patients seen within the past 3 years in a pediatric multidisciplinary concussion clinic for evaluation of postconcussive dizziness. Results: BPPV was diagnosed in 29.4% (30/102) of patients with postconcussion syndrome and dizziness. All patients with BPPV were treated with repositioning maneuvers, except for 5 patients who had spontaneous resolution of symptoms. Patients were evaluated at an average of 18.8 weeks (SD, 16.4 weeks) after the injury. BPPV was diagnosed at similar rates regardless of gender or age group (children vs adolescents). The mean Post-Concussion Symptom Scale (PCSS) score did not differ significantly between patients with (58.3 [SD, 22.5]) or without BPPV (55.8 [SD, 29.4]; P = 0.39). The PCSS “balance problems or dizziness” subscore also did not differ between patients with (3.3 [SD, 1.7]) or without BPPV (2.8 [SD, 1.6]; P = 0.13). Conclusion: BPPV is fairly common in pediatric concussion, occurring in one-third of the patients studied. BPPV is often not diagnosed and treated until many weeks after the injury. Increased awareness of the evaluation and management of BPPV among pediatric concussion providers may help expedite resolution of dizziness and hasten overall recovery in affected patients. Clinical Relevance: BPPV is a treatable cause of dizziness caused by minor head injuries and is more common than previously reported in pediatric patients with concussion. Improved awareness of BPPV by concussion providers may expedite recovery.

Abstract Background Oxymetazoline hydrochloride 0.1% ophthalmic solution has recently been approved in the United States for the treatment of ptosis. Objectives The aim of this study was to assess the upper and lower eyelid position as well as the brow position and the color of the sclera following the ophthalmic administration of oxymetazoline hydrochloride 0.1%. Methods In this prospective cohort study, consecutive patients presenting with ptosis received topical oxymetazoline 0.1%. The primary outcome was measurement of the upper eyelid height (margin-to-reflex distance 1 [MRD1]) and lower eyelid height (MRD2) relative to the center of pupil, along with assessment of brow height, measured on photographs at baseline and 2 hours after instillation of oxymetazoline. The secondary outcome was the assessment of the color of the sclera (eye whiteness) before and after treatment with a novel color space algorithm. Results Twenty-nine patients participated in the study. The mean [SD] MRD1 at baseline was 2.3 [0.6] mm. At 2 hours following oxymetazoline treatment, the mean MRD1 significantly increased to 4.2 [0.9] mm (P < 0.01). The mean MRD2 also significantly increased from 5.3 [0.9] mm to 5.7 [1.0] mm (P < 0.01). Brow position did not change with treatment (P = 0.4). Following treatment, the eye sclera became significantly whiter, with a mean ΔEab (color change) of 9.7 [3.9], with 57 out of 58 eyes experiencing a significant change in color. A change of ΔEab ≥2 is considered visually perceptible to the human eye. Conclusions Within 2 hours of use, oxymetazoline significantly improves the size of the palpebral aperture (MRD1 + MRD2) and also makes the eye appear significantly whiter. Level of Evidence: 4

Counts were made of the number of motoneurons innervating the hind limbs of 10-day normal and paralysed chick embryos whose right hind limb buds had been subjected to varying degrees of amputation prior to innervation. The number of motoneurons on the intact sides of the paralysed embryos was found to be similar to the number present in normal embryos prior to the major period of motoneuron death. Since it has previously been shown that paralysis does not increase the number of motoneurons generated, this means that normal motoneuron death was largely prevented in the paralysed embryos. There were differences in the distributions of motoneurons in the rostrocaudal axis of the spinal cord between normal and paralysed embryos. Therefore, cell death does not eliminate a uniform fraction of motoneurons throughout the rostrocaudal extent of the chick embryo lumbar lateral motor column. It is also argued that there are differences in the relative contribution of the various lumbosacral levels to different parts of the limb, e.g. the shank, before and after the period of cell death. In both normal and paralysed embryos there was a linear relationship between the volume of limb muscle which developed after amputation and the number of motoneurons surviving in the spinal cord. There was no evidence of a ‘compression’ of motoneurons into the remaining muscle either after amputation alone or after amputation combined with paralysis. Motoneurons are therefore rigidly specified for certain parts of the limb. The relationship between motoneuron number and muscle volume on the amputated side differed from that of the intact side. For a similar increase in muscle volume there was a smaller increase in motoneuron number on the intact sides. This suggested a parallel to the paradoxically small increase in motoneuron number that occurs on the addition of a supernumerary limb.

Objective: to investigate the relationship between adiponectin level and metabolic syndrome (MS) after weight loss in patients with abdominal obesity (AO). Method: A 3-year randomized lifestyle intervention trial performed in 153 patients with AO, age 43,2±0,8 yrs, BMI 32,1±1,9 kg/m 2 . 74 patients keep hypocaloric diet (gr.1), 79 patients keep diet and performed aerobic exercise (gr.2). Adiponectin concentration, body mass (BM), waist circumference (WC), body fat (BF), BMI, the levels of BP, glucose, insulin, HOMA-IR, TC, HDL-C, LDL-C, TG, CRP were measured before and after a 3-years outpatient intervention program. Results. 100% patients with AO had some metabolic disorders and 38% had MS before the treatment. The adiponectin levels and others parameters didn’t differ between the groups before intervention (p>0,05). In 3 years 53 (71,6%) and 58 (73,4%) patients from 1 and 2 groups reduced weight. The rate of improving BM, BMI, BF, WC, HDL-C, TG and insulin was grater in patients gr.2 (p<0,05). The favorable dynamics of MS (MS didn’t appeared at the end of study or didn’t registered in patients who had it before) didn’t differ between the groups 1 and 2 (81,1% and 91,4%, p>0,05). The increasing of adiponectin level occurred more often in patients gr.2, than gr.1 (93,1% and 58,5%, p=0,001, respectively). Adiponectin level increased only in patients gr.2 (18,0±1,1mcg/ml and 23,8±1,3 mcg/ml, p= [[Unable to Display Character: &#1088;]]=0,0001), didn’t changed in gr.1 (p>0,05). It was established that in patients with combination of weight loss and increasing of adiponectin level favorable dynamics of MS occurred more often than in patients who lost weight without increasing of adiponectin level (91,7% and 69,2%, p=0,0001). In patients with favorable dynamics of MS increasing of adiponectin level had met more often, than in patients with unfavorable dynamics of MS (MS continued or appeared) (88,6% and 11,4%, p=0,0001). Increasing of adiponectin level associated with positive dynamics of the MS - OR=9,1 (4,0-20,6). Conclusion. Combination of weight loss and increasing of adiponectin level associated with favorable dynamics of the metabolic syndrome.

ABSTRACT Introduction: Resistance exercise (RE) training is widely recommended for increasing muscle strength and mass in older adults. RE is also a potential stimulus to improve cognitive functions (CF), but the best protocol for this purpose is unknown. Objective: To compare the effects of different RE protocols on CF in the same group of individuals. Methods: Twenty-four older adults were randomized (cross over) to control (CON) and lower limb RE protocols with high load (HL - 80% of 1RM), low load (LL - 30% of 1RM) and LL with blood flow restriction (LL-BFR - 30% of 1RM and 50% BFR). For CF assessment, participants underwent the Stroop test before and after each RE protocol. Results: Reduction in response time for Stroop neutral stimuli was greater after LL (effect size (ES) = -0.92) compared to CON (ES = -0.18) and HL (ES = -0.03), but was not different from LL-BFR (ES = -0.24). The reduced response time was associated with reduced parasympathetic modulation and increased cardiac output across protocols. Conclusion: LL was the most effective RE protocol to improve CF of older adults and a potential beneficial effect of LL-BFR on CF (non-significant) was identified. Therefore, LL resistance exercise appears to stimulate acute cognitive improvements in healthy older adults, probably through exercise-induced optimal autonomic modulation changes.

ABSTRACT BACKGROUND: On 11 March 2020 the World Health Organization (WHO) declared COVID-19 a worldwide pandemic and a threat to global public health. In this paper we aim to describe the measures implemented to combat the COVID-19 pandemic in the Department of Orthopaedic Surgery at Chris Hani Baragwanath Academic Hospital (CHBAH), Soweto, Johannesburg, the largest hospital in Africa with approximately 3 200 beds and about 6 760 staff members. At the time of writing this report, we have transitioned from level 5 to level 3 lockdown METHODS: We performed a literature review and drew on the experiences of previous pandemic response plans worldwide. A working group comprising all relevant disciplines was created to develop standard operating procedures in line with governmental policy RESULTS: We found that by developing a multi-phase plan, we were able to maintain service delivery to all emergent patients while protecting medical staff and patients alike. This plan also allowed coordination with other disciplines and made provision for staff from within the Department of Orthopaedic Surgery to be made available to work within other departments as and when required. The implementation of this plan had to evolve constantly, adjusting to the changes in the national lockdown level and the demands of the developing situation CONCLUSION: We hope that by sharing our plan with our colleagues domestically and abroad, we can promote discussion and improve our ability to better prepare and deal with this unprecedented healthcare scenario. In order for us to win as individuals, we must fight as a team Level of evidence: Level 5 Keywords: COVID-19, orthopaedics, plan, response, Baragwanath

Purpose The development of new computer-assisted navigation technologies in total knee arthroplasty (TKA) has attracted great interest; however, the debate remains open as to the real reliability of these systems. We compared conventional TKA with last generation computer-navigated TKA to find out if navigation can reach better radiographic and clinical outcomes. Methods Twenty patients with tricompartmental knee osteoarthritis were prospectively selected for conventional TKA (n = 10) or last generation computer-navigated TKA (n = 10). Data regarding age, gender, operated side, and previous surgery were collected. All 20 patients received the same cemented posterior-stabilized TKA. The same surgical instrumentation, including alignment and cutting guides, was used for both the techniques. A single radiologist assessed mechanical alignment and tibial slope before and after surgery. A single orthopaedic surgeon performed clinical evaluation at 1 year after the surgery. Wilcoxon's test was used to compare the outcomes of the two groups. Statistical significance was set at p < 0.05. Results No significant differences in mechanical axis or tibial slope was found between the two groups. The clinical outcome was equally good with both techniques. At a mean follow-up of 15.5 months (range, 13–25 months), all patients from both groups were generally satisfied with a full return to daily activities and without a significance difference between them. Conclusion Our data showed that clinical and radiological outcomes of TKA were not improved by the use of computer-assisted instruments, and that the elevated costs of the system are not warranted. Level of Evidence This is a Level II, randomized clinical trial.

Poor Health Literacy

Background: Active participation in patients’ own care is essential for success after Lapidus procedure. Poor health literacy, comprehension, and retention of patient instructions may be correlated with patient participation. Currently, there is no objective measure of how well patients internalize and retain instructions before and after a Lapidus procedure. We performed this study to assess how much of the information given to patients preoperatively was able to be recalled at the first postoperative visit. Methods: All patients between ages 18 and 88 years undergoing a Lapidus procedure for hallux valgus by the senior author between June 2016 and July 2018 were considered eligible for inclusion. Patients were excluded if they had a history of previous bunion surgery or if the procedure was part of a flatfoot reconstruction. Patients were given written and verbal instructions at the preoperative visit. Demographic and comprehension surveys were administered at their first visit approximately 2 weeks postoperatively. A total of 50 patients, of which 42 (84%) were female and 43 (86%) had a bachelor’s degree or higher, were enrolled. Results: Mean overall score on the comprehension survey was 6.2/8 (±1.2), mean procedure subscore was 1.8/3 (±0.64), and mean postoperative protocol subscore was 4.4/5 (±0.8). The most frequently missed question asked patients to identify the joint fused in the procedure. Conclusion: Although comprehension and retention of instructions given preoperatively was quite high in our well-educated cohort, our findings highlight the importance of delivering clear instructions preoperatively and reinforcing these instructions often. Level of Evidence: Level II, prospective cohort study.
