It consists of a box that contains two small displays for stereoscopic visualization cheap 30 gm acticin fast delivery, thus one for each eye discount acticin 30gm otc. The user views the scene through this optic and sees the 3-D computer-generated world. The resolution of the BOOM depends naturally on the reso- lution of the used CRT, and it could be also monochrome. The SimStim is a head-coupled, monochrome, CRT-based stereoscopic viewing device with optics and tactile feedback. The Logitech US head tracker for sensing position and orientation has been integrated. Among its limitations is a disturbing image distortion caused by optics is perceivable. The Responsive Work- bench (German National Research Centre for Computer Science) belongs to this class (18). It is aimed at showing the possibilities for future cooperative work within a VR environment. The viewer walks into the SID environment and has the ``you are there' experience in the virtual world. The CAVE (CAVE Virtual Reality Theater) is a projection-based VR system (http://evlweb. Created by scientists at the Elec- tronic Visualization Laboratory in 1992, the CAVE is a 10 ft. It is a room with an open side and no ceiling in which the user can walk around wearing a pair of CrystalEyes glasses. The reproduction of a stationary or freely moveable sound source in space has to be exactly positioned. The acoustics parameters of the environ- ment should be changeable so that rooms of di¨erent sizes or outside environ- ments with all the involved re¯ections and transmissions can be modeled. The Acoustetron II of Crystal River Engineering is an interactive 3-D audio sound server that provides the full spectrum of 3-D sound to high-end graphics workstations, such as Silicon Graphics computers (http://www. It is controlled from a central simulation computer (the audio client) over a communication line (RS 232 by default).

It is specific to gait best acticin 30gm, and incorporates a patient database proven acticin 30 gm, a gait cycles window, and a report generator program called RGEN. The inputs to VCM are C3D files while the outputs are the GCD (gait cycle data) files based on the CAMARC standard. Oxford Metrics also manufactures a general purpose software package called BodyBuilder which enables the user to customise the biomechani- cal model to his or her own application.

The temporal resolution of Peak Systems is variable de- pending on the video recording system being used. The standard system arrangement uses 60 frames/s, although the Peak System is compatible with video recording equipment that can record at a rate of up to 200 frames/s. The advantages of these systems are as follows: Markers are not always required; movement can be cap- tured on videotape (even under adverse field and lighting condi- tions) and then processed by the computer at a later time; the soft- ware to process and display the kinematic information is very flex- ible, creating animated stick figures for quantitative analysis. The major disadvantages are that the video-based systems require con- siderable “hands-on” from the operator to digitise the data, and so the time from capturing the movement of interest to the availability of data can be quite lengthy. Peak Motus, which can accommodate up to 6 cameras, overcomes this disadvantage when passive retro- reflective targets are attached to the subject. An analogue acquisi- tion module enables the user to gather force plate, EMG and other data that are synchronised with the kinematic data. Passive retro-reflective targets are attached to the subject and these are illuminated by infra-red diodes that surround the lens in the MCU. The light is reflected back to the MCU and the 2D locations of up to 150 targets are calculated in real time. The ProReflex systems come in two versions, the MCU 240 (operating between 1 and 240 Hz) and the MCU 1000 (oper- ating between 1 and 1000 Hz). Up to 32 MCUs can be connected in a ring-type topology, thus providing complete coverage of any complex 3D movement, including gait. The spatial resolution is claimed to be 1:60,000 of the field of view, and the range of the MCUs is up to 75m. This system would therefore appear to be approaching the ideal device described by Lanshammer (1985) al- though there are still problems with unique target identification.

Anchor the perceptual range cheap 30 gm acticin fast delivery, which includes relating to the fact that no exertion at all is sitting still acticin 30gm line, and maximal exertion is a theoretical concept of pushing the body to its absolute physical limits. Patients should then be exposed to differing levels of exercise intensity (as in an incremental test or during an exercise session) so as to understand what the various levels on the scale feel like. Just giving them one or two points on the scale to aim for will probably result in a great deal of variability. Use the above points to explain the nature of the scale and explain that the patient should consider both the verbal descriptor and the numerical value. They should first concentrate on the sensations arising from the activity, look at the scale to see which verbal descriptor relates to the effort they are experiencing and then link it to the numerical value. Make sure the patient is not just concentrating on singular sensations, known as differentiated ratings (see Figure 3. Differentiated ratings can be used during muscular strength activity or where exercise is limited more by breathlessness or leg pain, and not cardiac limitations, as in the case pulmonary or peripheral vascular disease, respectively. There are three important cases where the patient may give an incorrect rating: a. When the patient already has a preconceived idea about what exertion level is elicited by a specific activity (Borg, 1998). He/she is not aware that what is required is to rate the amount of effort at this very moment, not what they think a typical level of exertion is for that activity. Similar to heart rate, RPEs should be taken while the patient is actually engaged in the movements, not after they have finished or in the break between stations. Simply pleasing the exercise practitioner by stating what should be the appropriate level is a regular observation in the author’s experience. In the early stages of rehabilitation, the patient’s exercise inten- sity should be set by HR or workrate (e. Once it has been established that the patient’s rating concurs with the target heart rate or MET level reliably, moving them on to production mode can be considered. It is known that endurance athletes in a race situation work very hard mentally to concentrate (cognitively associate) on their sen- sations in order to regulate their pace effectively (Morgan, 2000). ESTIMATED METABOLIC EQUIVALENTS The metabolic equivalent (MET) is widely used in cardiovascular population exercise guidelines as a means of quantifying the energy demands of physical activity.
