For example, in order for a person to get their arm through a shirt, the clinician may perform weightbearing to relax the biceps and the use electrical stimulation on the triceps. The goal of a skilled clinician is to assist a person return to a normal movement pattern by activating and strengthening the weaker muscles and turning off or inhibiting the spastic muscles. Moving the weakened muscle voluntarily or with use of electrical stimulation will help prevent muscle atrophy. Other treatments such as Botox injections or oral medications can also help to decrease the abnormal tone and movement patterns. Regular stretching, weightbearing, and splinting can be beneficial and help to maintain a good position of the affected limb. These predictable changes in movement and tone are described in the Brunnstrom Stages of Recovery.ĭuring stroke recovery, it is important to prevent the overactive muscle from getting to tight and the soft tissue from shortening. After a stroke, muscle tone often starts to increase slowly, continues to increases, then, with time and treatment tone can decrease again. The predictable movement patterns include tight flexor muscles and weak extensor muscles. Neurologist Vladimar Janda suggests that muscle imbalances and movement impairments follow predictable movement patterns, especially following an upper motor neuron lesion such as a stroke. This abnormal tone and movement often affects all activities of daily living. Some of the shoulder muscles are now more active, whereas others are much weaker now. An example we often see after a stroke is a stroke survivor lifting the entire shoulder toward the ear to elevate the affected arm when reaching forward or getting dressed. For example when the hand is closing into a fist.Ībnormal muscle tone also affects the ability to perform voluntary movements. A decrease in range of motion can lead to joint contractures and soft tissue shortening. Weakness or loss of movement in a limb are usually immediately apparent following a stroke and often contribute to decrease in active and passive range of motion. This abnormal tone usually occurs in the side of the body opposite to the side of the brain lesion. This is known as hypotonic or flaccid or a muscle may increase in muscle tone. A single muscle or a muscle group may become completely paralyzed. Following a stroke, abnormal muscle tone is a common complication.

Depending on the difficulty, monsters spawn in darker areas outside a certain radius of the character, requiring players to build a shelter at night. In this mode, players have to gather natural resources such as wood and stone found in the environment in order to craft certain blocks and items. The original and core gameplay element of the game. Survival Main article: Survival (Game Mode) Players are then allowed to teleport back to their original spawn point in the Overworld and continue the game indefinitely. There is also another portal that access the outer islands of The End, in which players could access the outer islands. Killing the dragon opens access to an exit portal, which upon entering cues the game's ending credits and a poem written by Irish novelist Julian Gough. A boss dragon called the Ender Dragon dwells on the main island. The End is a barren land consisting of many islands. The player can build an optional boss mob called the Wither out of materials found in the Nether. The Nether is a hell-like dimension accessed via player-built portals it contains many unique resources and can be used to travel great distances in the Overworld. Minecraft has two alternate dimensions besides the Overworld (the main world): the Nether and the End. There are also variants of mobs that spawn in different conditions for example, Zombies have Husk variants that spawn in deserts. Other creatures unique to Minecraft include the Creeper (an exploding creature that sneaks up on the player) and the Enderman (a creature with the ability to teleport, pick up, and place blocks). Some hostile mobs, such as the Zombie, Skeleton, and Drowned (underwater versions of Zombies), burn under the sun if they have no headgear. They spawn in the daytime, while hostile mobs, including large spiders, skeletons, and zombies-spawn during nighttime or in dark places such as caves. Passive mobs, such as cows, pigs, and chickens, can be hunted for food and crafting materials. Players encounter various non-player characters known as mobs, such as animals, villagers, and hostile creatures. Players can select any customized skin whenever they want to, but new players start with the default character skin of either Steve or Alex. The game also contains a material known as redstone, which can be used to make mechanical devices, electrical circuits, and logic gates, allowing for the construction of many complex systems. The gameplay is in the first-person perspective by default, but players have the option for a third-person perspective. In Creative mode, players are free to roam in the world wherever they want, and just simply build anything that comes within their imagination, like cities, redstone machines, etc. The most prominent objective in Survival mode, is to get precious stuff to upgrade certain weapons or tools or make convenient armors that would help them throughout their journeys. In Survival mode, players must gather resources from the Overworld, hunt for food to replenish health and hunger, and protect themselves from the deadly hostile mobs that attack them during nighttime, or in cave systems. There are two game modes in the game: Survival and Creative. There is no right or wrong way to play the game, players can play the game however they want it to be. While the gameplay revolves through the players' experiences, the game encourages many players to choose their own way of "adventure". Minecraft is a game that has no specific goals to accomplish, allowing players a large amount of freedom in choosing how to play it. The face of a block is 16 by 16 pixels, and each block is proportionately one cubic meter. They can be used in crafting and manipulated in many other ways. They can be broken, collected, and placed in an infinite number of arrangements. Blocks make up the Minecraft landscape and are integral to gameplay. |
