Abstract
To date, there is a paucity of information in the literature regarding the association between cervical range of motion (CROM) and skin caliper measures (SCM) and swallowing outcomes in post-RT individuals with head and neck cancer. Also lacking in the literature are reports of the effect of swallowing exercises and neck stretches on changes in CROM and SCM and their associations with swallowing outcomes. The aim of this study was to assess the associations between CROM and SCM before initiation of a neck stretching and swallowing exercise program and to determine if 12 weeks of twice daily practice changes in CROM and SCM were associated with changes in swallowing outcomes in a cohort of 119 head and neck cancer survivors. Primary results revealed that at baseline, greater right and left CROM were associated with lower penetration aspiration scale (PAS) scores (r = - 0.321, p = < 0.001; r = - 0.203, p = 0.026, respectively). Improved skin pliability revealed lower PAS scores (r = - 0.210, p = 0.022). After 12 weeks, there were no significant correlations between changes in CROM and SCM and PAS scores. Changes in left CROM and CROM extension had positive associations with the Head and Neck Cancer Inventory eating score (r = 0.210, p = 0.026; r = 0.245, p = 0.009, respectively). Findings appear to indicate that any improvement was not associated with changes in swallowing outcomes. Head and neck cancer survivors may perceive improved diet and swallowing skills through exercise, with respect to improved CROM extension.

Physical therapy in sport : official journal of the Association of Chartered Physiotherapists in Sports Medicine. 2020;:1-7
Abstract
OBJECTIVE The purpose of this study was to determine if WBV performed concurrently with static stretching was more effective than static stretching alone to increase dorsiflexion ROM (DFROM) in individuals with chronic ankle instability (CAI). DESIGN Controlled laboratory study. PARTICIPANTS Thirty-nine participants with CAI (history of ankle sprain, a feeling of "giving way" during activity, and a qualifying Foot and Ankle Ability Measure Ankle score) were divided into 3 groups (normative (N), static stretch (SS), and static stretch with vibration (SV)). Participants stretched the triceps surae 4 days/wk for 3 wks. Vibration was imposed at 34 Hz and 1.8 mm. MAIN OUTCOME MEASURES DFROM was assessed in a straight and bent-leg position. RESULTS No differences were detected at any time in the N or SS group, however SS did exhibit large effect sizes with 95% confidence intervals (CI) that did not cross zero from baseline to 3 weeks for both measures. The SV group demonstrated increased DFROM from baseline for both time points and a large effect size with 95% CI that did not cross zero from post tx-1 to post tx-2. CONCLUSIONS Static stretching with WBV increases DFROM in participants with CAI more effectively than static stretching alone.

Abstract
PURPOSE To compare and evaluate knee laxity and functional outcomes between autologous bone graft and silicate-substituted calcium phosphate (Si-CaP) in the treatment of tunnel defects in 2-stage revision anterior cruciate ligament reconstruction (ACLR). METHODS This prospective, randomized controlled trial was conducted between 2012 and 2015 with a total of 40 patients who underwent 2-stage revision ACLR. The tunnels were filled with autologous iliac crest cancellous bone graft in 20 patients (control group) and with Si-CaP in the other 20 patients (intervention group). After a minimum follow-up period of 2 years, functional outcomes were assessed by KT-1000 arthrometry (side-to-side [STS] difference), the Tegner score, the Lysholm score, and the International Knee Documentation Committee score. RESULTS A total of 37 patients (follow-up rate, 92.5%) with an average age of 31 years were followed up for 3.4 years (range, 2.2-5.5 years). The KT-1000 measurement did not show any STS difference between the bone graft group (0.9 ± 1.5 mm) and the Si-CaP group (0.7 ± 2.0 mm) (P = .731). One patient in the intervention group (5%) had an STS difference greater than 5 mm. Both groups showed significant improvements in the Tegner score, Lysholm score, and International Knee Documentation Committee score from preoperative assessment to final follow-up (P ≤ .002), without any difference between the 2 groups (P ≥ .396). Complications requiring revision occurred in 4 control patients (22%) and in 2 patients in the intervention group (11%) (P = .660). No complications in relation to Si-CaP were observed. CONCLUSIONS Equivalent knee laxity and clinical function outcomes were noted 3 years after surgery in both groups of patients. Si-CaP bone substitute is therefore a safe alternative to autologous bone graft for 2-stage ACLR. LEVEL OF EVIDENCE Level I, prospective, randomized controlled clinical trial.

Abstract
PURPOSE Restricted shoulder mobility is a major upper extremity dysfunction associated with lower quality of life and disability after breast cancer surgery. We hypothesized that a poloxamer and sodium alginate mixture (Guardix-SG®) applied after axillary lymph node dissection (ALND) would significantly improve shoulder range of motion (ROM) in patients with breast cancer. METHODS We conducted a double-blind, randomized, prospective study to evaluate the clinical efficacy and safety of Guardix-SG® for the prevention of upper extremity dysfunction after ALND. The primary outcome measure was shoulder ROM at baseline (T0) and 3 (T1), 6 (T2), and 12 months (T3) after surgery. Secondary outcome measures were the Disabilities of the Arm, Shoulder, and Hand score(DASH), pain associated with movement, which was assessed using a numeric rating scale, and lymphedema assessed using body composition analyzer. RESULTS A total of 83 women with breast cancer were randomly assigned to either the Guardix-SG® group or the control group. In the Guardix-SG® group (n = 37), Guardix-SG® was applied to the axillary region after ALND. In the control group (n = 46), ALND was performed without using Guardix-SG®. Comparing ROM for shoulder flexion before surgery (178.2°) and 12 months after surgery (172.3°), that was restored 12 months after surgery in the Guardix-SG® group, and there was no statistically significant difference between that at before surgery and 12 months after surgery (p = 0.182). No adverse effect was observed in either group. CONCLUSIONS The results of this study have shown that Guardix-SG® help improve shoulder ROM without causing adverse effects in patients who underwent breast cancer surgery. However, there was no statistically significant difference from the control group. A further large-scale study is needed to obtain a more conclusive conclusion.

Abstract
BACKGROUND Osteoarthritis (OA) is a major degenerative disease that affects the elderly. The global prevalence of OA is increasing annually. However, current treatments are unable to halt the progress of OA. At present, pharmacological treatments such as non-steroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase-2 (COX-2) inhibitors control the pain; however, there may be side effects to these medications. We hypothesized that Cortex Eucommiae (CE; Eucommia ulmoides Oliver) extract, which is used as a dietary supplement, may slow down or prevent OA. METHODS This is a protocol for a 12-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of CE extract in subjects with mild OA. One-hundred subjects with mild OA will be recruited and randomly divided in a 1:1 ratio into 2 groups. One group will receive CE extract for 12 weeks and the other group will receive placebo for 12 weeks. Outcomes will be evaluated by using the visual analog scale (VAS), Korean-Western Ontario and McMaster Universities index (K-WOMAC), Korean-Short Form health survey-36 score (KSF-36), and laboratory test results. DISCUSSION This clinical trial is expected to provide evidence of the efficacy and safety of CE extract as a treatment for mild OA.

Abstract
BACKGROUND Progressive weight gain and changes in its distribution following pregnancy may be challenging for the gravidas' ability to move in a stable way. RESEARCH QUESTION How is gait kinematics changing throughout pregnancy and to what extend is it affected by physical activity level and energy balance? METHODS 30 women were enrolled. Three experimental sessions were arranged according to the same protocol in the first, second and third trimesters of pregnancy. Walking kinematics at a self-selected speed was registered. The total physical activity (TPA) was assessed from the subjects' questionnaires. Energy balance ('positive', 'balanced' or 'negative') was estimated as the difference between dietary energy intake and energy expenditure during 7 days. RESULTS No significant differences were found in the spatiotemporal variables between experimental sessions. However, the gait analysis revealed significant increments in the single support and base of support (BoS) measures. Generally, the sagittal plane mobility of the lower limb joints did not differ, however, the pelvic tilt increased in late pregnancy. The hip and pelvis angles were significantly different over the gait cycle throughout gestation. The 'balanced' energy was dominant in the first trimester although the relative number of participants with negative balance increased over pregnancy. Overall, gait parameters were independent of the energy balance. However, significant correlation was found between gait parameters, such as BoS, velocity, stride length, and TPA in the advanced pregnancy. SIGNIFICANCE The longitudinal assessment of walking kinematics demonstrates few changes adopted to accommodate for pregnancy. The enlargement of BoS is considered as a strategy to provide safety and stability. The increased pelvic tilt is likely to compensate for changes in the body mass distribution. The physical activity correlates with the BoS measures and stride length and thus may be important for enhancing gait stability.

Arnold, JB, Marshall, M, Thomas, MJ, Redmond, AC, Menz, HB, Roddy, E
Osteoarthritis and cartilage. 2019;(4):659-666
Abstract
OBJECTIVE To investigate the demographic, symptomatic, clinical and structural foot characteristics associated with potential phenotypes of midfoot osteoarthritis (OA). DESIGN Cross-sectional study of 533 community-dwelling adults aged ≥50 years with foot pain in the past year. Health questionnaires and clinical assessments of symptoms, foot structure and function were undertaken. Potential midfoot OA phenotypes were defined by the pattern of radiographic joint involvement affecting either the medial midfoot (talonavicular, navicular-1st cuneiform, or cuneiform-1st metatarsal joint), central midfoot (2nd cuneiform-metatarsal joint), or both medial and central midfoot joints. Multivariable regression models with generalised estimating equations were used to investigate the associations between patterns of midfoot joint involvement and symptomatic, clinical and structural characteristics compared to those with no or minimal midfoot OA. RESULTS Of 879 eligible feet, 168 had medial midfoot OA, 103 central midfoot OA, 76 both medial and central midfoot OA and 532 no/minimal OA. Having both medial and central midfoot OA was associated with higher pain scores, dorsally-located midfoot pain (OR 2.54, 95%CI 1.45, 4.45), hallux valgus (OR 1.76, 95%CI 1.02, 3.05), flatter foot posture (β 0.44, 95%CI 0.12, 0.77), lower medial arch height (β 0.02, 95%CI 0.01, 0.03) and less subtalar inversion and 1st MTPJ dorsiflexion. Isolated medial midfoot OA and central midfoot OA had few distinguishing clinical characteristics. CONCLUSIONS Distinct phenotypes of midfoot OA appear challenging to identify, with substantial overlap in symptoms and clinical characteristics. Phenotypic differences in symptoms, foot posture and function were apparent in this study only when both the medial and central midfoot were involved.

Gretebeck, KA, Blaum, CS, Moore, T, Brown, R, Galecki, A, Strasburg, D, Chen, S, Alexander, NB
Journal of physical activity & health. 2019;(6):461-469
Abstract
Background: Diabetes-related disability occurs in approximately two-thirds of older adults with diabetes and is associated with loss of independence, increased health care resource utilization, and sedentary lifestyle. The objective of this randomized controlled trial was to determine the effect of a center-based functional circuit exercise training intervention followed by a 10-week customized home-based program in improving mobility function in sedentary older adults with diabetes. Methods: Participants (n = 111; mean age 70.5 [7.1] y; mean body mass index 32.7 [5.9] kg/m2) were randomized to either a moderate-intensity functional circuit training (FCT) plus 10-week home program to optimize physical activity (FCT-PA) primary intervention or one of 2 comparison groups (FCT plus health education [FCT-HE] or flexibility and toning plus health education [FT-HE]). Results: Compared with FT-HE, FCT-PA improvements in comfortable gait speed of 0.1 m/s (P < .05) and 6-minute walk of 80 ft were consistent with estimates of clinically meaningful change. At 20 weeks, controlling for 10-week outcomes, improvements were found between groups for comfortable gait speed (FCT-PA vs FT-HE and FCT-HE vs FT-HE) and 6-minute walk (FCT-PA vs FCT-HE). Conclusions: Functional exercise training can improve mobility in overweight/obese older adults with diabetes and related comorbidities. Future studies should evaluate intervention sustainability and adaptations for those with more severe mobility impairments.

The Acute Effects of a "Reduced Sitting Preschool Day" on Executive Function and Musculoskeletal Health in Preschoolers: A Randomized Cross-Over Study.
Ellis, YG, Cliff, DP, Howard, SJ, Okely, AD
Pediatric exercise science. 2019;(4):505-513
Abstract
PURPOSE To examine the acute effects of a reduced sitting day on executive function (EF) and musculoskeletal health in preschoolers. METHODS A sample of 29 children (54% boys; 4-5 y) participated in a randomized cross-over trial. Each child completed 2 protocols, which simulate a day at childcare in random order for 2.5 hours; a typical preschool day (50% sitting) and a reduced preschool day (25% sitting) where most sitting activities were replaced with standing activities. Sitting, standing, and stepping time were objectively assessed using an activPAL accelerometer. EF was evaluated using tablet-based EF assessments (inhibition, working memory, and task shifting). Musculoskeletal health was assessed using a handheld dynamometer and goniometer. RESULTS Compared with the typical preschool day, the reduced sitting day showed no significant differences for EF scores. Effect sizes for inhibition (d = 0.04), working memory (d = 0.02), and shifting (d = 0.11) were all small. For musculoskeletal health, no significant differences were reported after the reduced preschool day. The effect sizes for the hip extension force, hamstring flexibility, gastrocnemius length, and balancing on 1 leg were all small (d = 0.21, d = 0.25, d = 0.28, and d = 0.28). CONCLUSIONS This study suggests that reducing sitting time is unlikely to result in acute changes in EF and musculoskeletal health among preschoolers.

Milk-Fat Globule Membrane Plus Glucosamine Improves Joint Function and Physical Performance: A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study.
Suzukamo, C, Ishimaru, K, Ochiai, R, Osaki, N, Kato, T
Journal of nutritional science and vitaminology. 2019;(3):242-250
Abstract
Care of the musculoskeletal system, including the muscles, joints, and bones, is important for a healthy life expectancy in today's aging society. The aim of this randomized, double-blind, placebo-controlled study was to investigate the effect of consumption of milk-fat globule membrane (MFGM) and glucosamine on joint function and physical performance. Participants were healthy Japanese men and women, aged 60-74 y, with a history of mild knee or low back pain at rest. They were randomized to receive tablets containing MFGM 1.0 g+glucosamine 1.5 g or placebo tablets for 8 wk. We assessed passive range of motion, active range of motion (self-reported VAS score), JKOM and JLEQ, and physical performance. Data were available for analysis for 25 participants in the active treatment group and 28 in the placebo group. The active group showed significant improvements in passive range of motion at the knee and active range of motion at both the knee and low back. The active group also showed significant improvements in some physical performance, including obstacle walking speed and speed of ascending stairs. The findings of this study suggest that consumption of a combination of MFGM and glucosamine may improve joint function and physical performance.
