ObjectiveTo determine the effect of prophylactic dextrose gel for prevention of neonatal hypoglycaemia on neurodevelopment and executive function at 2 years’ corrected age.DesignProspective follow-up of a randomised trial.SettingNew Zealand.PatientsParticipants from the pre-hypoglycaemia Prevention with Oral Dextrose (pre-hPOD) trial randomised to one of four dose regimes of buccal 40% dextrose gel or equivolume placebo.Main outcome measuresCoprimary outcomes were neurosensory impairment and executive function. Secondary outcomes were components of the primary outcomes, neurology, anthropometry and health measures.ResultsWe assessed 360 of 401 eligible children (90%) at 2 years’ corrected age. There were no differences between dextrose gel dose groups, single or multiple dose groups, or any dextrose and any placebo groups in the risk of neurosensory impairment or low executive function (any dextrose vs any placebo neurosensory impairment: relative risk (RR) 0.77, 95% CI 0.50 to 1.19, p=0.23; low executive function: RR 0.50, 95% CI 0.24 to 1.06, p=0.07). There were also no differences between groups in any secondary outcomes. There was no difference between children who did or did not develop neonatal hypoglycaemia in the risk of neurosensory impairment (RR 1.05, 95% CI 0.68 to 1.64, p=0.81) or low executive function (RR 0.73, 95% CI 0.34 to 1.59, p=0.43).ConclusionProphylactic dextrose gel did not alter neurodevelopment or executive function and had no adverse effects to 2 years’ corrected age, but this study was underpowered to detect potentially clinically important effects on neurosensory outcomes.

Background Children and young people make up an age group most vulnerable to falls. Various stability disorders may become instrumental in sustaining more frequent falls and resultant fractures. Correct morphological structure impacts overall efficiency of the foot, as well as offers significant diagnostic potential. Even minor foot disorders may affect the entire bio kinematic chain, also impacting the foot’s motility. Structural alterations within a foot may also impair balance in the standing position, and contribute to more frequent injuries. The study aimed to assess the relationship between feet deformities and postural stability deficits in schoolchildren prone to sustain accidental falls. Methods The study involved 200 children (101 girls and 99 boys) aged 10–15 years, randomly selected from primary schools. A 2D podoscan was used to assess the plantar part of the foot, while stabilometric examination was aided by the FreeMed dynamometric platform. Results Correlation between respective variables was reflected by Spearman’s rank coefficient. The subjects’ age negatively correlated with the COP range of movement along the Y axis, and the COP surface area, while their BMI negatively correlated with the COP trajectory’s length. Step regression analysis indicated that the width of the left foot, the left foot Wejsflog index, the left foot Clark’s angle, the hallux valgus angle were the essential predictors of stabilometric variables in girls. In boys, though, predictive value was associated with Clarke’s angle of the left and right foot, Wejsflog index of the right foot, and the width of both the left and right foot. Conclusions There is a statistically significant correlation between morphological variables of the foot and postural stability. When assessing the key variables of the foot and their interrelationship with postural stability, the Clarke’s angle, Wejsflog index, hallux valgus angle, and foot width, should be granted due prominence in the girls. As regards the boys, the following variables were established as predictive in assessing postural stability: Clarke’s angle, Wejsflog index, and foot width.

Background Complaints of imbalance are common non-resolving signs in individuals with post-concussive syndrome. Yet, there is no consensus rehabilitation for non-resolving balance complaints following mild traumatic brain injury (mTBI). The heterogeneity of balance deficits and varied rates of recovery suggest varied etiologies and a need for interventions that address the underlying causes of poor balance function. Our central hypothesis is that most chronic balance deficits after mTBI result from impairments in central sensorimotor integration that may be helped by rehabilitation. Two studies are described to 1) characterize balance deficits in people with mTBI who have chronic, non-resolving balance deficits compared to healthy control subjects, and 2) determine the efficacy of an augmented vestibular rehabilitation program using auditory biofeedback to improve central sensorimotor integration, static and dynamic balance, and functional activity in patients with chronic mTBI. Methods Two studies are described. Study 1 is a cross-sectional study to take place jointly at Oregon Health and Science University and the VA Portland Health Care System. The study participants will be individuals with non-resolving complaints of balance following mTBI and age- and gender-matched controls who meet all inclusion criteria. The primary outcome will be measures of central sensorimotor integration derived from a novel central sensorimotor integration test. Study 2 is a randomized controlled intervention to take place at Oregon Health & Science University. In this study, participants from Study 1 with mTBI and abnormal central sensorimotor integration will be randomized into two rehabilitation interventions. The interventions will be 6 weeks of vestibular rehabilitation 1) with or 2) without the use of an auditory biofeedback device. The primary outcome measure is the daily activity of the participants measured using an inertial sensor. Discussion The results of these two studies will improve our understanding of the nature of balance deficits in people with mTBI by providing quantitative metrics of central sensorimotor integration, balance, and vestibular and ocular motor function. Study 2 will examine the potential for augmented rehabilitation interventions to improve central sensorimotor integration.

Somatosensory function declines with age, and such changes have been associated with diminished motor performance. Input noise can enhance sensory and motor function. We asked young and elderly participants to stand quietly on vibrating gelbased insoles, and calculated sway parameters and random-walk variables. In our 27 participants, application of noise resulted in a reduction in seven of eight sway parameters in young participants and all of the sway variables in elderly participants. Elderly participants showed greater improvement than young people in two variables, mediolateral range (p=0·008), and critical mean square displacement (p=0·012). Noise-based devices, such as randomly vibrating insoles, could ameliorate age-related impairments in balance control.

Background After open thyroidectomy, patients usually complain of voice, sensory, and swallowing symptoms. We approached the thyroid via the subfascial method to reduce these symptoms and compared postthyroidectomy symptoms with the conventional subplatysmal method. Methods Eighty-six patients undergoing thyroidectomy were recruited and randomized into either a conventional subplatysmal approach group (subplatysmal, 42 patients) group or a subanterior fascia of strap muscle approach group (subfascial, 44 patients). Voice symptoms were assessed using the Voice Handicap Index questionnaire and acoustic voice analysis. Sensory alterations were evaluated by the light touch and pain touch methods. Swallowing symptoms were assessed using the Swallowing Impairment Score (SIS) questionnaire, barium swallowing time, and hyoid bone movement range. Each variable was measured preoperatively, and at 2 weeks and 3 months after thyroidectomy. Results In both groups, the subjective symptoms of voice, sensation, and swallowing were significantly worsened at 2 weeks after operation, but improved 3 months after operation. Patients in the subplatysmal group had worse SIS scores than patients in the subfascial group ( p  = 0.016) and delayed barium swallowing time 2 weeks after operation ( p  = 0.008 compared to preoperative level). In the cohort over 50 years of age, SIS score did not recover to preoperative levels in the subplatysmal group 3 months after operation ( p  = 0.005 compared to preoperative level). Conclusions The subfascial approach may be an effective method for reducing postthyroidectomy swallowing symptoms based on swallowing impairment score, especially in patients over 50 years of age.

Background and Purpose. Traditionally, rehabilitation programs emphasize training balance under single-task conditions to improve balance and reduce risk for falls. The purpose of this case report is to describe 3 balance training approaches in older adults with impaired balance. Case Descriptions. Three patients were randomly assigned to 1 of 3 interventions: (1) single-task balance training, (2) dual-task training under a fixed-priority instructional set, and (3) dual-task training under a variable-priority instructional set. Outcomes. The patients who received balance training under dual-task conditions showed dual-task training benefits; these training benefits were maintained for 3 months. The patient who received variable-priority training showed improvement on novel dual tasks. Discussion. Older adults may be able to improve their balance under dual-task conditions only following specific types of balance training. This case report gives insight on how this intervention might be combined with more traditional physical therapy intervention. [Silsupadol P, Siu KC, Shumway-Cook A, Woollacott MH.

Balance impairment is a frequent and undertreated manifestation in ankylosing spondylitis, leading to increased risk of falls and lower quality of life. Our aim was to assess supervised training and home-based rehabilitation efficacy on balance improvement in ankylosing spondylitis subjects on biologic agents. This was a single-blinded, quasi-randomized parallel study in a single outpatient Rehabilitation Clinic of a tertiary referral center. Subjects with ankylosing spondylitis on biologic agents were assigned either to supervised training and home-based rehabilitation program (rehabilitation group) plus educational–behavioral therapy, or to educational–behavioral therapy alone (educational groups). The same therapist provided therapy. Outcome measures were assessed at baseline (T0), end of treatment (T1) and at 7-month follow-up (T2). Rheumatologic outcomes were Bath Ankylosing Spondylitis Metrology Index, Bath Ankylosing Spondylitis Functional Index and Bath Ankylosing Spondylitis Disease Activity Index. Balance parameters (anterior–posterior oscillation, latero-lateral oscillation, sway area, sway density and sway path) were evaluated by stabilometry in a condition of open and closed eyes. Forty-six subjects (36 M, 10 F) were enrolled. Demographic data and clinical status at baseline were comparable between the two groups (22 rehabilitation group, 20 educational group). Primary outcome was sway density that improved both at T1 (SDy: open eyes p  = 0.003, closed eyes p  = 0.004) and at T2 (SDx: open eyes p  = 0.0015, closed eyes p  = 0.032). A trend toward improvement in the rehabilitation group rather than in the educational group emerged for balance parameters, especially those measured with closed eyes (0.004 <  p  < 0.048 at T1 and 0.004 <  p  < 0.036 at T2). Supervised training and home exercise lead to balance improvement in people with ankylosing spondylitis. Eyes-closed trials show a more marked trend toward improvement, and this may suggest a positive effect of rehabilitation on proprioception.

Background Cervicogenic dizziness is a disabling condition characterised by postural unsteadiness that is aggravated by cervical spine movements and associated with a painful and/or stiff neck. Two manual therapy treatments (Mulligan’s Sustained Natural Apophyseal Glides (SNAGs) and Maitland’s passive joint mobilisations) are used by physiotherapists to treat this condition but there is little evidence from randomised controlled trials to support their use. The aim of this study is to conduct a randomised controlled trial to compare these two forms of manual therapy (Mulligan glides and Maitland mobilisations) to each other and to a placebo in reducing symptoms of cervicogenic dizziness in the longer term and to conduct an economic evaluation of the interventions. Methods Participants with symptoms of dizziness described as imbalance, together with a painful and/or stiff neck will be recruited via media releases, advertisements and mail-outs to medical practitioners in the Hunter region of NSW, Australia. Potential participants will be screened by a physiotherapist and a neurologist to rule out other causes of their dizziness. Once diagnosed with cervciogenic dizziness, 90 participants will be randomly allocated to one of three groups: Maitland mobilisations plus range-of-motion exercises, Mulligan SNAGs plus self-SNAG exercises or placebo. Participants will receive two to six treatments over six weeks. The trial will have unblinded treatment but blinded outcome assessments. Assessments will occur at baseline, post-treatment, six weeks, 12 weeks, six months and 12 months post treatment. The primary outcome will be intensity of dizziness. Other outcome measures will be frequency of dizziness, disability, intensity of cervical pain, cervical range of motion, balance, head repositioning, adverse effects and treatment satisfaction. Economic outcomes will also be collected. Discussion This paper describes the methods for a randomised controlled trial to evaluate the effectiveness of two manual therapy techniques in the treatment of people with cervicogenic dizziness for which there is limited established evidence-based treatment.

Sensory processing abnormalities, anxiety and restricted and repetitive behaviours (RRBs) frequently co-occur in Autism Spectrum Disorders (ASD). Though the relationship between these phenomena is not well understood, emerging evidence indicates intolerance of uncertainty (IU) may play an important role. This study aimed to determine pathways between sensory abnormalities and RRBs, and the role anxiety and IU may have. We gathered caregiver report data for 53 children with ASD aged 8–16 years. We found sensory under responsiveness and sensory over responsiveness were significantly associated with repetitive motor and insistence on sameness behaviours, and the relationships significantly mediated by IU and anxiety. Our findings indicate different mechanisms may underpin repetitive motor and insistence on sameness RRBs, which can inform treatment interventions.

Patients undergoing radiation therapy for the head and neck are susceptible to a significant and often abrupt deterioration in their oral health. The oral morbidities of radiation therapy include but are not limited to an increased susceptibility to dental caries and periodontal disease. They also include profound and often permanent functional and sensory changes involving the oral soft tissue. These changes range from oral mucositis experienced during and soon after treatment, mucosal opportunistic infections, neurosensory disorders, and tissue fibrosis. Many of the oral soft tissue changes following radiation therapy are difficult challenges to the patients and their caregivers and require life‐long strategies to alleviate their deleterious effect on basic life functions and on the quality of life. We discuss the presentation, prognosis, and management strategies of the dental structure and oral soft tissue morbidities resulting from the administration of therapeutic radiation in head and neck patient. A case for a collaborative and integrated multidisciplinary approach to the management of these patients is made, with specific recommendation to include knowledgeable and experienced oral health care professionals in the treatment team. Oral complications of radiation therapy to the head and neck can result in acute and long‐term deterioration in oral soft tissues and dentition. The presentation, prognosis, and strategies to manage the dental and nondental morbidities of radiation therapy to the head and neck are discussed in this manuscript.
