Abstract:
Three main objectives are pursued with this study. The first is to summarise some current ideas about the origin and nature of stereotypic movements. The second is to present some music-therapeutic approaches to the phenomenon: different examples with a behaviouristic background are given; an educational approach is touched on; and Nordoff-Robbins' work is represented with a practical example. Thirdly, I discuss a case from my personal experience. My practical experience with stereotypies in music therapy was at the time of writing limited to one child.

Abstract:
Stereotypies stand out as the most debated aspect within the spectrum of repetitive behaviors observed in childhood, which encompass mannerisms,habits, compulsions, tics, and other sudden movements. Stereotypies refer to a repetitive, persistent, often rhythmic pattern of non-purposeful motor actions that may disrupt social interaction, academic performance, or other daily activities, and can potentially lead to physical harm. Many young children exhibit stereotyped behaviors, such as thumb sucking. In older children and adults, repetitive behaviors like finger tapping or drumming, self-stimul

Insects are capable of efficient locomotion in a spatially complex environment, such as walking on a forest floor or climbing in a bush. One behavioural mechanism underlying such adaptability is the searching movement that occurs after loss of ground contact. Here, the kinematic sequence of leg searching movements of the stick insect Carausius morosus is analysed. Searching movements are shown to be stereotypic rhythmic movement sequences consisting of several loops. The typical loop structure allows the mean tarsus trajectory to be calculated using a feature-based averaging procedure. Thus, i

AbstractThe effects of age and context on the stereotypies of caged mink were examined in order to assess the developmental changes undergone by the behaviour, and to find context-specificity that might suggest its motivational bases. Caged mink perform stereotypies consisting of a variety of movements, most commonly pacing and rearing, running in and out of the nestbox, and stationary head-twirling or nodding. Stereotypies are largely performed as feeding-time approaches, and many mink do not show them at all once fed. Stereotypies become more frequent and less variable with age; and in adult

AbstractThe motor deficits observed in patients following some lesions of the central nervous system may be viewed as falling at one extreme of the continuum of possible motor behaviours. They are usually associated with an impaired ability to select and control specific movements from the available repertoire. Such movements may not be viewed as abnormal. However, it is unlikely that the primary motor deficits can all be considered adaptive.

Abstract:
Background: Some typical and atypical Rett syndrome patients lack known genetic mutations. Mutations in the P/Q type calcium channel CACNA1A have been implicated in epileptic encephalopathy, familial hemiplegic migraine, episodic ataxia 2, and spinocerebellar ataxia 6, but not Rett syndrome. Patient Description: The authors describe a female patient with developmental regression and a de novo, likely pathogenic mutation in CACNA1A who meets 3 of 4 main criteria (stereotypic hand movements, loss of purposeful hand movements, gait disturbance), and 6 of 11 supportive criteria (impaired sleep, ab

Abstract:
To maintain tissue architecture, epithelial cells divide in a planar fashion, perpendicular to their main polarity axis. As the centrosome resumes an apical localization in interphase, planar spindle orientation is reset at each cell cycle. We used three-dimensional live imaging of GFP-labeled centrosomes to investigate the dynamics of spindle orientation in chick neuroepithelial cells. The mitotic spindle displays stereotypic movements during metaphase, with an active phase of planar orientation and a subsequent phase of planar maintenance before anaphase. We describe the localization of the

Abstract:
Herbivorous fishes form a keystone component of reef ecosystems, yet the functional mechanisms underlying their feeding performance are poorly understood. In water, gravity is counter-balanced by buoyancy, hence fish are recoiled backwards after every bite they take from the substrate. To overcome this recoil and maintain contact with the algae covered substrate, fish need to generate thrust while feeding. However, the locomotory performance of reef herbivores in the context of feeding has hitherto been ignored. We used a three-dimensional high-speed video system to track mouth and body kinema

For conducting the experiment under laboratory conditions, a dedicated workplace was designed to simulate the activity of lifting / lowering a 20 kg load to a height of 0.7 m in the “Squat” and “Stoop” styles. To implement this study, the following methods were employed: “motion capture” to assess the mechanics of movements in the lumbar spine; a non-invasive method for measurement of the key biological indicators as a comprehensive assessment of the state of the cardiorespiratory system; electromyography (EMG) as the main method for assessing the bioelectrical activity of muscles; interviewin

Abstract:
The acoustic startle response is an evolutionarily conserved avoidance behavior. Disruptions in startle behavior, particularly startle magnitude, are a hallmark of several human neurological disorders. While the neural circuitry underlying startle behavior has been studied extensively, the repertoire of genes and genetic pathways that regulate this locomotor behavior has not been explored using an unbiased genetic approach. To identify such genes, we took advantage of the stereotypic startle behavior in zebrafish larvae and performed a forward genetic screen coupled with whole genome analysis.

AbstractForty-eight budgerigars (Melopsittacus undulatus) were pairwise housed in small (80 × 40 × 50 cm) and large (160 × 40 × 50 cm) (length × breadth × height) boxes, as well as in 2.0 × 1.0 × 2.0 m aviaries. All boxes and aviaries had two or three (aviaries) perches and food was offered on the bottom. The body masses of female budgerigars increased significantly when they were housed in boxes instead of aviaries. The size of the box did not influence body mass. The frequency of flying was adjusted to the size of the box as both males and females flew approximately twice as often from perch

Along with domestication, various changes in nutrition and digestion have occurred in horses as well as in all species. Our review aims to compile existing studies examining the role of nutrition and digestion in the emergence of undesirable behaviours in domestic horses. The success achieved in species with high adaptability has not been sustained by the change in breeding purposes over the years. Welfare, defined as the physical and mental health of animals. The responses of animals to various stimuli are defined as behaviour. Since the behaviour of animals plays a primary role in monitoring
