In vertebrates ageing is characterised by reduced viscoelasticity of the ligamentous and tendineous structures and fibre changes in muscle. Also, some vertebral joint degeneration develops with ageing. The aim of this study was to apply dynamic time warping to compare the temporal characteristics of the surface electromyography (sEMG) data and to illustrate the differences in the pattern of muscle use during tasks of daily life in old and mature horses. In vivo kinematics (24 skin markers) and sEMG measurements of neck extensors and flexors were taken in five mature horses (aged 10±2 years, half of mean life expectancy) and five old horses (aged 25±5 years, older than the mean life expectancy). All horses had the same level of activity in the 12 months prior to the measurement. Tasks measured were neck flexion and neck extension as well as neutral neck position. Muscle activation, minimum and maximum muscle activation were collected. Quartiles of muscle activity based on the maximum observed activity of each muscle were calculated to document the relative increase of activity level during the task. Kinematics as well as overall muscle activity patterns were similar across horses and age groups. However, in the neutral position old horses showed increased extensor activity compared to mature horses, indicating that old equine muscle requires more activity to counteract gravity. Dynamic time warping specified optimal temporal alignments of time series, and different temporal performances were identified. The age groups differed during the flexion task, while neck extension and neutral neck position were more similar. The results of this study show that even in the second half of life and in the absence of muscle disuse the muscular strategy employed by horses continues to be adapted.

Masticatory Muscle Activity

Introduction: It is considered now-a-days that patients with transverse craniofacial deformity might have differences in masticatory muscle activity between both sides; and as masticatory muscle activity takes place throughout the usual daily life; therefore, it might have some relation with the transverse craniofacial morphology. The present study was carried out to find out any association between balance of masticatory  muscle activity during usual daily life and transverse craniofacial morphology or tooth contact area in patients with transverse jaw deformity.Subjects and Methods: All the controls and patients for the study were selected from our staffs and patients coming to Orthodontic Clinic, Hiroshima University Dental Hospital, respectively. Thirteen males and two females (mean and s.d. of ages: 28.6 ± 1.9 years) served as the controls. They had Angle’s Class I molar relationship, no severe malocclusion, no complaints of temporomandibular disorder (TMD).The patient group was consisted of 10 males and five females (mean and s.d. of ages: 19.9 ± 5.3 years) with lateral shift of the mandible. They had malocclusion such as cross-bite and severe crowding, but no complaints of TMD. Portable digital EMG recording device were used to record the EMG from the bilateral masster and anterior temporal muscles. The diurnal recording was carried out for consecutive 142 minutes and divided into two periods of usual daytime and mealtime for analysis. After the diurnal recording, the subjects were allowed to go back home with the electrodes in position and then nocturnal EMG recording was performed again at night with the usual sleeping posture for 142 minutes. Posteroanterior cephalometric analysis and tooth contact area were measured for all the subjects.Result: No significant correlations were found for both the muscles neither with transverse craniofacial morphology nor with the tooth contact area for all the three periods of usual daily life, although a significant correlation was detected between the A-B distance and AI of the anterior temporal muscle during usual daytime.Conclusion: It is suggested that masticatory muscle activity during usual daily life in patients with transverse craniofacial deformity may not be related only to such factors as skeletal deformity or tooth contact area but governed by other important factors like occlusal interference, premature contacts, instability and so on.Ban J Orthod & Dentofac Orthop, October 2012; Vol-3, No.1

Electromyography Signals

Due to a sedentary lifestyle, the amount of people suffering from musculoskeletal back diseases has increased over the last few decades. To monitor and cure these disabilities, sensors able to monitor the patient for long-term measurement during daily life and able to provide real-time feedback are required. There are only a few wearable systems that are capable to acquire muscle activity (sEMG) and posture at the same time. Moreover, previously reported systems do not target back sensor and typically comprise bulky uncomfortable solutions. In this paper, we present a new wearable sensor network that is designed to measure muscle activity and posture specialized for back measurement. Special care was taken to propose a discrete and comfortable solution. The prototype only measures 3.1 mm in thickness on the spine, making this sensor system the thinnest and lightest one in the literature to our best knowledge. After testing, it was shown that the sensor system is able to acquire two surface electromyography signals concurrently, to gather acceleration and rotation speed from the patient’s lower back, and to transmit data to a computer or a smartphone via serial communication or Bluetooth low energy for a few hours for later processing and analysis.

Counseling Adolescents

Abstract Audiologists have a responsibility to counsel patients with auditory concerns on methods to manage the inherent challenges associated with hearing loss at every point in the process: evaluation, hearing aid fitting, and follow-up visits. Adolescents with hearing loss struggle with the typical developmental challenges along with communicative challenges that can erode one's self-esteem and self-worth. The feeling of “not being connected” to peers can result in feelings of isolation and depression. This article advocates the use of a Narrative Therapy approach to counseling adolescents with hearing loss. Adolescents with hearing loss often have problem-saturated narratives regarding various components of their daily life, friendships, amplification, academics, etc. Audiologists can work with adolescents with hearing loss to deconstruct the problem-saturated narratives and rebuild the narratives into a more empowering message. As the adolescent retells their positive narrative, they are likely to experience increased self-esteem and self-worth.

Lower Variability

Abstract. Most research in health psychology is based on retrospective self reports, which are distorted by recall biases and have low ecological validity. To overcome such limitations we developed computer assisted diary approaches to assess health related behaviours in individuals’, couples’ and families’ daily life. The event- and time-sampling-based instruments serve to assess appraisals of the current situation, feelings of physical discomfort, current emotional states, conflict and emotion regulation in daily life. They have proved sufficient reliability and validity in the context of individual, couple and family research with respect to issues like emotion regulation and health. As examples: Regarding symptom reporting curvilinear pattern of frequencies over the day could be identified by parents and adolescents; or psychological well-being is associated with lower variability in basic affect dimensions. In addition, we report on preventive studies to improve parental skills and enhance their empathic competences towards their baby, and towards their partner.
