ItemPhysical Therapists' Perceptions of Telephone- and Internet Video-Mediated Service Models for Exercise Management of People With Osteoarthritis(WILEY, 2018-03-01)OBJECTIVE: To investigate physical therapists' perceptions of, and willingness to use, telephone- and internet-mediated service models for exercise therapy for people with knee and/or hip osteoarthritis. METHODS: This study used an internet-based survey of Australian physical therapists, comprising 3 sections: 1 on demographic information and 2 with 16 positively framed perception statements about delivering exercise via telephone and video over the internet, for people with hip and/or knee osteoarthritis. Levels of agreement with each statement were evaluated. Logistic regression models were used to determine therapist characteristics influencing interest in delivering telerehabilitation. RESULTS: A total of 217 therapists spanning metropolitan, regional, rural, and remote Australia completed the survey. For telephone-delivered care, there was consensus agreement that it would not violate patient privacy (81% agreed/strongly agreed) and would save patient's time (76%), but there was less than majority agreement for 10 statements. There was consensus agreement that video-delivered care would save a patient's time (82%), be convenient for patients (80%), and not violate patient privacy (75%). Most agreed with all other perception statements about video-delivered care, except for liking no physical contact (14%). Low confidence using internet video technologies, and inexperience with telerehabilitation, were significantly associated with reduced interest in delivering telephone and/or video-based services. CONCLUSION: Physical therapists agree that telerehabilitation offers time-saving and privacy advantages for people with osteoarthritis and perceive video-delivered care more favorably than telephone-delivered services. However, most do not like the lack of physical contact with either service model. These findings may inform the implementation of telerehabilitation osteoarthritis services and the training needs of clinicians involved in delivering care.

ItemInternet Cognitive-Behavioral Therapy for Depression in Older Adults With Knee Osteoarthritis: A Randomized Controlled Trial(WILEY, 2018-01-01)OBJECTIVE: To determine the efficacy of an internet-based cognitive-behavioral therapy (iCBT) program for depression in older adults with osteoarthritis (OA) of the knee and comorbid major depressive disorder (MDD). METHODS: We conducted a randomized controlled trial in 69 adults (ages ≥50 years) meeting criteria for MDD and OA of the knee with 1-week postintervention (week 11) and 3-month followup (week 24) end points. Patients were allocated to either a 10-week iCBT program for depression added to treatment as usual (TAU) or to a TAU control group. Primary outcomes were depression symptoms (9-Item Patient Health Questionnaire [PHQ-9]) and psychological distress (Kessler-10 [K-10]). Secondary outcomes included arthritis self-efficacy (Arthritis Self-Efficacy Scale [ASES]), OA pain, stiffness, physical function (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]), and physical and mental health (Short Form 12-Item health survey physical component and mental component summaries). Depression status was assessed by blinded diagnostic interview (the Mini-International Neuropsychiatric Interview) at intake and followup. RESULTS: Intent-to-treat analyses indicated between-group superiority of iCBT over TAU on the primary outcomes (PHQ-9: Hedges g = 1.01, 95% confidence interval [95% CI] 0.47, 1.54; K-10: Hedges g = 0.75, 95% CI 0.23, 1.28), at postintervention and 3-month followup (PHQ-9: Hedges g = 0.90, 95% CI 0.36, 1.44; K-10: Hedges g = 0.94, 95% CI 0.41, 1.48), and on secondary OA-specific measures (ASES: Hedges g = -0.81, 95% CI -0.29, -1.33; WOMAC: Hedges g = 0.56-0.65, 95% CI 0.04, 1.18) at the 3-month followup. The majority of iCBT participants (84%) no longer met diagnostic criteria at 3-month followup. CONCLUSION: Results support the efficacy of an iCBT program (requiring no face-to-face contact) for depression in individuals with comorbid depression and OA of the knee. Importantly, the benefits of the program extended beyond reduced depressive symptoms and distress to include increased self-efficacy and improved pain, stiffness, and physical function at followup.

ItemMagnetic resonance imaging of the upper airway in patients with quadriplegia and obstructive sleep apnea(WILEY, 2018-08-01)The aim of this study was to investigate upper airway anatomy in quadriplegics with obstructive sleep apnea. Fifty subjects were recruited from three hospitals in Australia: people with quadriplegia due to spinal cord injury and obstructive sleep apnea (n = 11), able-bodied people with obstructive sleep apnea (n = 18), and healthy, able-bodied controls (n = 19). All underwent 3-Tesla magnetic resonance imaging of their upper airway. A subgroup (n = 34) received a topical vasoconstrictor, phenylephrine and post-phenylephrine magnetic resonance imaging. Mixed-model analysis indicated no significant differences in total airway lumen volume between the three groups (P = 0.086). Spinal cord injury-obstructive sleep apnea subjects had a significantly larger volume of soft palate (P = 0.020) and retroglossal lateral pharyngeal walls (P = 0.043) than able-bodied controls. Able-bodied-obstructive sleep apnea subjects had a smaller mandible volume than spinal cord injury-obstructive sleep apnea subjects and able-bodied control subjects (P = 0.036). No differences were seen in airway length between groups when controlling for height (P = 0.055). There was a marginal increase in velopharyngeal volume across groups post-phenylephrine (P = 0.050), and post hoc testing indicated the difference was confined to the able-bodied-obstructive sleep apnea group (P < 0.001). No other upper airway structures showed significant changes with phenylephrine administration. In conclusion, people with obstructive sleep apnea and quadriplegia do not have a structurally smaller airway than able-bodied subjects. They did, however, have greater volumes of soft palate and lateral pharyngeal walls, possibly due to greater neck fat deposition. The acute response to upper airway topical vasoconstriction was not enhanced in those with obstructive sleep apnea and quadriplegia. Changes in upper airway anatomy likely contribute to the high incidence in obstructive sleep apnea in quadriplegic subjects.

ItemThe role of social risk in an early preventative care programme for infants born very preterm: a randomized controlled trial(WILEY, 2018-01-01)AIM: To examine the differential effects of an early intervention programme for infants born preterm on neurodevelopment and parental mental health according to family social risk. METHOD: One hundred and twenty infants born earlier than 30 weeks' gestation were randomized to early intervention (n=61) or control groups (n=59). Cognitive, language, and motor outcomes were assessed by blinded assessors at 2 years, 4 years, and 8 years, and primary caregivers completed questionnaires on their anxiety and depression. Outcomes at each time point were compared between groups using linear regression with an interaction term for social risk (higher/lower). RESULTS: There was evidence of interactions between intervention group and social risk for cognition at 2 years and 4 years, motor function at 4 years, and language at 8 years, with a greater intervention effect in children from higher social risk environments. In contrast, the impact of early intervention on parental depressive symptoms was greater for parents of lower social risk than for those of higher social risk. INTERPRETATION: Effects of early intervention on outcomes for children born preterm and their caregivers varied according to family social risk. Family social risk should be considered when implementing early intervention programmes for children born preterm and their families. WHAT THIS PAPER ADDS: Intervention is associated with better early cognitive functioning for children in higher social risk families. Positive effects of intervention for the high risk group were not sustained at school-age. Intervention has a greater effect on primary caregiver mental health in the lower social risk group compared with higher social risk.

ItemPreterm and term-equivalent age general movements and 1-year neurodevelopmental outcomes for infants born before 30weeks' gestation(WILEY, 2018-01-01)AIM: To examine the associations between Prechtl's General Movements Assessment (GMA), conducted from birth to term-equivalent age, and neurodevelopmental outcomes at 12 months corrected age, in infants born very preterm. METHOD: One hundred and thirty-seven infants born before 30 weeks' gestation had serial GMA (categorized as 'normal' or 'abnormal') before term and at term-equivalent age. At 12 months corrected age, neurodevelopment was assessed using the Alberta Infant Motor Scale (AIMS); Neurological, Sensory, Motor, Developmental Assessment (NSMDA); and Touwen Infant Neurological Examination (TINE). The relationships between GMA at four time points and 12-month neurodevelopmental assessments were examined using regression models. RESULTS: Abnormal GMA at all time points were associated with worse continuous scores on the AIMS, NSMDA, and TINE (p<0.05). Abnormal GMA before term and at term-equivalent age were associated with increased odds of mild-severe dysfunction on the NSMDA (odds ratio [OR] 4.26, 95% confidence interval [CI] 1.55-11.71, p<0.01; and OR 4.16, 95% CI 1.55-11.17, p<0.01 respectively) and abnormal GMA before term with increased odds of suboptimal-abnormal motor function on the TINE (OR 2.75, 95% CI 1.10-6.85, p=0.03). INTERPRETATION: Abnormal GMA before term and at term-equivalent age were associated with worse neurodevelopment at 12 months corrected age in children born very preterm. WHAT THIS PAPER ADDS: Abnormal general movements before term predict developmental deficits at 1 year in infants born very preterm. General Movements Assessment before term identifies at-risk infants born very preterm.

ItemHip abductor muscle activity during walking in individuals with gluteal tendinopathy(WILEY, 2018-02-01)The external hip adduction moment during walking is greater in individuals with gluteal tendinopathy (GT) than pain-free controls. Although this likely represents a greater demand on the hip abductor muscles implicated in GT, no study has investigated activation of these muscles in GT. For this purpose, fine wire electrodes were inserted into the segments of the gluteus minimus and medius muscles, and surface electrodes placed on the tensor fascia lata, upper gluteus maximus, and vastus lateralis muscles of eight individuals with, and eight without, GT. Participants underwent six walking trials. Individual muscle patterns were compared between groups using a wavelet-based linear effects model and muscle synergy analysis performed using non-negative matrix factorization to evaluate muscle activation patterns, within- and between-participant variability. Compared to controls, individuals with GT exhibited a more sustained initial burst of the posterior gluteus minimus and middle gluteus medius muscle segments. Two muscle synergies were identified; Synergy-1 activated in early-mid stance and Synergy-2 in early stance. In GT participants, posterior gluteus minimus and posterior gluteus medius and tensor fascia lata contributed more to Synergy-1 active during the period of single leg support. Participants with GT exhibited reduced within-participant variability of posterior gluteus medius and reduced between-participant variability of anterior gluteus minimus and medius and upper gluteus maximus. In conclusion, individuals with GT exhibit modified muscle activation patterns of the hip abductor muscles during walking, with potential relevance for gluteal tendon loading.

ItemModerators of Effects of Internet-Delivered Exercise and Pain Coping Skills Training for People With Knee Osteoarthritis: Exploratory Analysis of the IMPACT Randomized Controlled Trial(JMIR PUBLICATIONS, INC, 2018-05-01)BACKGROUND: Internet-delivered exercise, education, and pain coping skills training is effective for people with knee osteoarthritis, yet it is not clear whether this treatment is better suited to particular subgroups of patients. OBJECTIVE: The aim was to explore demographic and clinical moderators of the effect of an internet-delivered intervention on changes in pain and physical function in people with knee osteoarthritis. METHODS: Exploratory analysis of data from 148 people with knee osteoarthritis who participated in a randomized controlled trial comparing internet-delivered exercise, education, and pain coping skills training to internet-delivered education alone. Primary outcomes were changes in knee pain while walking (11-point Numerical Rating Scale) and physical function (Western Ontario and McMaster Universities Osteoarthritis Index function subscale) at 3 and 9 months. Separate regression models were fit with moderator variables (age, gender, expectations of outcomes, self-efficacy [pain], education, employment status, pain catastrophizing, body mass index) and study group as covariates, including an interaction between the two. RESULTS: Participants in the intervention group who were currently employed had significantly greater reductions in pain at 3 months than similar participants in the control group (between-group difference: mean 2.38, 95% CI 1.52-3.23 Numerical Rating Scale units; interaction P=.02). Additionally, within the intervention group, pain at 3 months reduced by mean 0.53 (95% CI 0.28-0.78) Numerical Rating Scale units per unit increase in baseline self-efficacy for managing pain compared to mean 0.11 Numerical Rating Scale units (95% CI -0.13 to 0.35; interaction P=.02) for the control group. CONCLUSIONS: People who were employed and had higher self-efficacy at baseline were more likely to experience greater improvements in pain at 3 months after an internet-delivered exercise, education, and pain coping skills training program. There was no evidence of a difference in the effect across gender, educational level, expectation of treatment outcome, or across age, body mass index, or tendency to catastrophize pain. Findings support the effectiveness of internet-delivered care for a wide range of people with knee osteoarthritis, but future confirmatory research is needed.

ItemNo Additive Effects of Polyphenol Supplementation and Exercise Training on White Adiposity Determinants of High-Fat Diet-Induced Obese Insulin-Resistant Rats.(Hindawi Limited, 2018)One of the major insulin resistance instigators is excessive adiposity and visceral fat depots. Individually, exercise training and polyphenol intake are known to exert health benefits as improving insulin sensitivity. However, their combined curative effects on established obesity and insulin resistance need further investigation particularly on white adipose tissue alterations. Therefore, we compared the effects on different white adipose tissue depot alterations of a combination of exercise and grape polyphenol supplementation in obese insulin-resistant rats fed a high-fat diet to the effects of a high-fat diet alone or a nutritional supplementation of grape polyphenols (50 mg/kg/day) or exercise training (1 hr/day to 5 days/wk consisting of treadmill running at 32 m/min for a 10% slope), for a total duration of 8 weeks. Separately, polyphenol supplementation and exercise decreased the quantity of all adipose tissue depots and mesenteric inflammation. Exercise reduced adipocytes' size in all fat stores. Interestingly, combining exercise to polyphenol intake presents no more cumulative benefit on adipose tissue alterations than exercise alone. Insulin sensitivity was improved at systemic, epididymal, and inguinal adipose tissues levels in trained rats thus indicating that despite their effects on adipocyte morphological/metabolic changes, polyphenols at nutritional doses remain less effective than exercise in fighting insulin resistance.
