Ataxia is a neurological sign consisting of lack of voluntary coordination of muscle movements that can include gait abnormality, speech changes, abnormalities in eye movements. Ataxia is a clinical manifestation indicating dysfunction of the parts of the nervous system that coordinate movement, such as the cerebellum. Ataxia can be limited to one side of the body, referred to as hemiataxia. Several possible causes exist for these patterns of neurological dysfunction. Dystaxia is a mild degree of ataxia. Friedreich's ataxia has gait abnormality as the most presented symptom; the word is from Greek α- + -τάξις = "lack of order". The term cerebellar ataxia is used to indicate ataxia, due to dysfunction of the cerebellum; the cerebellum is responsible for integrating a significant amount of neural information, used to coordinate smoothly ongoing movements and to participate in motor planning. Although ataxia is not present with all cerebellar lesions, many conditions affecting the cerebellum do produce ataxia.
People with cerebellar ataxia may have trouble regulating the force, direction and rhythm of muscle contractions. This results in a characteristic type of irregular, uncoordinated movement that can manifest itself in many possible ways, such as asthenia, delayed reaction time, dyschronometria. Individuals with cerebellar ataxia could display instability of gait, difficulty with eye movements, dysphagia, hypotonia and dysdiadochokinesia; these deficits can vary depending on which cerebellar structures have been damaged, whether the lesion is bilateral or unilateral. People with cerebellar ataxia may present with poor balance, which could be demonstrated as an inability to stand on one leg or perform tandem gait; as the condition progresses, walking is characterized by a widened base and high stepping, as well as staggering and lurching from side to side. Turning is problematic and could result in falls; as cerebellar ataxia becomes severe, great assistance and effort are needed to walk. Dysarthria, an impairment with articulation, may be present and is characterized by "scanning" speech that consists of slower rate, irregular rhythm and variable volume.
There may be slurring of speech, tremor of the voice and ataxic respiration. Cerebellar ataxia could result with incoordination of movement in the extremities. There is overshooting with finger to nose testing, heel to shin testing. Impairments with alternating movements, as well as dysrhythmia, may be displayed. There may be tremor of the head and trunk in individuals with cerebellar ataxia, it is thought that dysmetria is caused by a deficit in the control of interaction torques in multijoint motion. Interaction torques are created at an associated joint. For example, if a movement required reaching to touch a target in front of the body, flexion at the shoulder would create a torque at the elbow, while extension of the elbow would create a torque at the wrist; these torques increase as the speed of movement increases and must be compensated and adjusted for to create coordinated movement. This may, explain decreased coordination at higher movement velocities and accelerations. Dysfunction of the vestibulocerebellum impairs the control of eye movements.
This presents itself with postural instability, in which the person tends to separate his/her feet upon standing, to gain a wider base and to avoid titubation. The instability is therefore worsened when standing with the feet together, regardless of whether the eyes are open or closed; this is a negative Romberg's test, or more it denotes the individual's inability to carry out the test, because the individual feels unstable with open eyes. Dysfunction of the spinocerebellum presents itself with a wide-based "drunken sailor" gait, characterised by uncertain starts and stops, lateral deviations, unequal steps; as a result of this gait impairment, falling is a concern in patients with ataxia. Studies examining falls in this population show that 74–93% of patients have fallen at least once in the past year and up to 60% admit to fear of falling. Dysfunction of the cerebrocerebellum presents as disturbances in carrying out voluntary, planned movements by the extremities; these include: intention tremor.
Inability to perform alternating movements, known as dysdiadochokinesia. This could involve switching from pronation to supination of the forearm. Movements become more irregular with increases of speed. Inability to judge distances or ranges of movement; this is known as dysmetria and is seen as undershooting, hypometria, or overshooting, the required distance or range to reach a target. This is sometimes seen when a patient is asked to reach out and touch someone's finger or touch his or her own nose; the rebound phenomenon known as the loss of the check reflex is sometimes seen in patients with cerebellar ataxia. For example, when a patient is flexing his or her elbow isometrically against a resistance; when the resistance is remo
The Geneva International Motor Show is an annual auto show held in March in the Swiss city of Geneva. The show is hosted at the Palexpo, a convention centre located next to the Geneva Cointrin International Airport; the Salon is organised by the Organisation Internationale des Constructeurs d'Automobiles, is considered an important major international auto show. First held in 1905, the Salon has hosted all major internal combustion engined models in the history of the automobile, along with benzene- and steam-powered cars from the beginning of the century. Exotic supercars steal the spotlight during their debuts at the show. Prototypes, new equipment, technical breakthroughs, international partnerships, as well as political and social debates, have been announced at the exhibition; the show is regarded as a level playing field for the world's automakers, aided by the fact Switzerland lacks an auto industry of its own. Areas of the show: Motor cars 3 or 4 or more wheels. Electric cars and alternative powered cars.
Special bodywork for motor cars, car design, engineering. Converted cars. Accessories and parts for motor cars OEM: original equipment manufacturers Workshop installations for the repair and maintenance of motor cars Miscellaneous products and services related to the car industry Animation / Attractions; the International Advanced Mobility Forum is the Geneva Motor Show forum on the mobility of the future.

The 2004 European Athletics Indoor Cup was held on 14 February 2004 at the Arena Leipzig in Leipzig, Germany. It was the second edition of the indoor track and field meeting for international teams, which featured the eight top performing nations from the 2003 European Cup, it was the second consecutive year that the event was held at the venue, following on from a successful hosting of the 2003 European Athletics Indoor Cup. The competition featured nine for men and ten for women; the 400 metres race were held in a dual final format due to size constraints, with athletes' being assigned final positions through their finishing times. The international team points totals were decided by their athletes' finishing positions, with each representative's performance contributing towards their national overall score; the Russian women's team retained their title from the previous year, taking a comprehensive victory – seven of the ten women's events were won by Russians and the team was eighteen points clear of runner-up Germany.
The men's side was a much more contested affair. The title was decided in the final Swedish medley relay event, with France just managing to maintain its lead and beat the Russian men by two points in the final rankings.

John Beach is a beach on the west side of the entrance to Walker Bay on the south coast of Livingston Island, in the South Shetland Islands. The ice-free area is around 109 hectares; the beach was charted and named "Black Point" by Robert Fildes in 1820–22. As there was a Black Point on Livingston Island, this name was rejected and a new one substituted by the UK Antarctic Place-Names Committee in 1958. John Beach is named after the brig John of London, sealing in the South Shetland Islands in 1820–21 and 1821–22. L. L. Ivanov et al.
