Olfactory and gustatory impairment: damage of the sense of smell and taste.

Somatosensory impairment: Is a lack of sensitivity to stimuli such as touch, heat, cold, and pain.

Balance disorder: Is a disturbance that causes an individual to feel unstable, for example when standing or walking.

3) Mental disability Intellectual disability or also well known as mental retardation is a inability characterized by significant restriction in intellectual functioning and adaptive behavior as expressed in practical skills and social. In this type of impairment is also including:

- Mental health and emotional disabilities that is a psychological or behavioral illness.

- Developmental disability that is a mentally or physically impairment that is develop in the early age and has an indefinite duration.

Into physical disability we can include:

Intellectual Disability: Is a broad concept encompassing various intellectual deficits.

Types of Intellectual disability include: Mental retardation, Specific learning disability, Acquired brain injury, Neuro-degeneration, Dementia.

Causes:

a) Genetic conditions: Sometimes disability is caused by abnormal genes inherited from parents, errors when genes combine, or other reasons.

b) Problems during pregnancy. Mental disability can result when the fetus does not develop properly. For example, there may be a problem with the way the fetus' cells divide as it grows.

c) Problems at birth. If a baby has problems during labor and birth, such as not getting enough oxygen, he or she may have developmental disability due to brain damage.

d) Malnutrition is a common cause of reduced intelligence in parts of the world affected by famine, such as Ethiopia.

e) Heredity – Learning disabilities often run in the family.

The IPC primarily serves athletes with physical disabilities, but the disability group Intellectual Disability has been added to some Paralympic Games. This includes only elite athletes with intellectual disabilities, where few qualify. The IOC recognized Special Olympics World Games however, are open to all persons with intellectual disabilities, also persons with severe and profound levels of intellectual disabilities.

Cerebral Palsy: Is an umbrella term encompassing a group of non-progressive, non-contagious motor conditions that cause physical disability in human development, chiefly in the various areas of body movement. Cerebral refers to the cerebrum, which is the affected area of the brain (although the disorder most likely involves connections between the cortex and other parts of the brain such as the cerebellum), and palsy refers to disorder of movement.

Types of Cerebral Palsy include: Spastic, Ataxia, and Athetoid/Dyskinetic.

Causes In certain cases there is no identifiable cause, typical causes include problems in intrauterine development (e.g. exposure to radiation, infection), asphyxia before birth, hypoxia of the brain, and birth trauma during labor and delivery, and complications in the perinatal period or during childhood. Athletes with non-progressive brain damage, for example cerebral palsy, traumatic brain injury, stroke or similar disabilities affecting muscle control, balance or coordination.

Exist also a group of disability that is not included in the groups above. This group is called:



Les Autres: From the French for the others, this includes persons with mobility impairment or other loss of physical function that does not fall strictly into one of the other five categories. Participants include those with dwarfism, multiple sclerosis or other disabilities. Athletes with a physical disability that does not fall strictly under one of the other five categories, such as dwarfism, multiple sclerosis or congenital deformities of the limbs such as that caused by thalidomide (the name for this category is the French for "the others").

2.2.1. Sports classes

Each Paralympic Sport has a different classification system, because each sport requires different abilities. Impairments therefore do not affect activity in different sports to the same extent. Athletes with one of these physical disabilities are able to compete in the Paralympics though not every sport can allow for every disability category. These categories apply to both Summer and Winter Paralympics (Table 1).

Archery: Included impairment types: physical impairment. Archery has historically been used for hunting and combat. Is the art, practice, or skill of propelling arrows with the use of a bow, from Latin arcus. Sport Classes: Paralympic archers are divided into three sport classes:

ARW1: Archers in this sport class compete in a wheelchair because their impairment includes the loss of leg and trunk function. Also, their arms show a loss of muscle strength, co-ordination or range of movement (spinal cord and cerebral palsy athletes with impairment in all four limbs). For example, one condition that might fit this sport class profile is tetraplegia2.

ARW2: Archers in this sport class have a strong activity limitation in their trunk and legs and compete in a wheelchair. Their arms however, show normal function (wheelchair users with full arm function). This profile would likely apply to paraplegic3 archers.

ARST: Includes athletes competing in a standing position and those who require some standing support because of poor balance. They either have a leg-length difference, limb deficiency or impairments that also affect their arms and trunk (athletes who have no disabilities in their arms but who have some disability in their legs). This group also includes amputees, les autres and cerebral palsy standing athletes.

Athletics: Included impairment types: physical impairment, visual impairment and intellectual impairment Is an exclusive collection of sporting events that involve competitive running, jumping, throwing, and walking. The most common types of athletics competitions are track and field, road running, cross country running, and race walking. All disability groups can compete in athletics but a system of letters and numbers is used to distinguish between them. A letter F is for field athletes, T represents those who compete on the track, and the number shown refers to their disability. Sport Classes: Paralympic athletics are divided into three sport classes:

T/F11-13: visual impairment: The three sport classes 11, 12 and 13 are allocated to athletes with varying degrees of visual impairment, with sport class 11 including athletes with the lowest vision and sport class 13 including athletes with the best vision meeting the minimum disability criteria. All athletes in the T11 sport class run with a guide runner and are blindfolded. Athletes in sport class T12 may also chose to run with a guide.

T/F 20: Intellectual impairment: Athletes in this class are diagnosed with intellectual impairment and meet sport specific minimum disability criteria in 1,500m, long jump or shot put, respectively.

T32-38 and F31-38: The 30s sport classes are allocated to athletes with athetosis, ataxia and/or hypertonia. The impairments typically affect the ability to control legs, trunk, arms and hands. The lower the number is, the more significant the activity limitation.

F40: Athletes with short stature compete in the sport class F40.

T/F42-46: These sport classes are designated for athletes with limb deficiencies, such as amputations. In the sport classes 42-44 the legs are affected by impairment and in the sport classes 45-46 the arms are affected, for example by above or below elbow amputations.

T51-54 and F51-58: The 50s sport classes only include athletes competing in a wheelchair. Again, a lower number indicates a higher activity limitation. Athletes competing in wheelchair racing events for T51-54 sport classes differ in regards to their arm and shoulder functions, which are pertinent for pushing a wheelchair. Athletes in classes T51-52 have activity limitations in both lower and upper limbs, for example, due to tetraplegia. Unlike athletes in the sport classes T51-53, athletes competing in T54 have partial trunk and leg function.

Boccia: Included impairment types: physical impairment. Is a traditional recreational sport, similar to bocce. The name Boccia is derived from the Latin word for boss – bottia. Boccia is open to athletes with cerebral palsy and other severe physical disabilities (eg, muscular dystrophy) that compete from a wheelchair, Sport Classes: Paralympic boccia are divided into three sport classes:

BC1: Athletes may compete with the help of an assistant, who must remain outside the athlete's playing box. The assistant can only stabilize or adjust the playing chair and give a ball to the player on his request.

BC2: Athletes have poor functional strength in their extremities, but can propel a wheelchair and are not eligible for assistance.

BC3: For players with a very severe physical disability. Players use an assistive device and may be assisted by a person, who will remain in the player's box but who must keep his/her back to the court and eyes averted from play.

BC4: For players with other severe physical disabilities - not necessarily cerebral palsy. Players are not eligible for assistance.

Cycling: Included impairment types: physical impairment, visual impairment. Is a competition sport in which various types of bicycles are used. There are several categories of bicycle racing including road bicycle racing, cyclo-cross, mountain bike racing, track cycling, BMX, bike trials, and cycle speedway. Cycling is open to amputees, les autres, athletes with cerebral palsy and visually impaired athletes, competing in individual road race and track events. Athletes with cerebral palsy are split into four divisions according to the level of their disability, where class four comprises the more physically able. Visually impaired athletes compete together with no separate classification system. They ride in tandem with a sighted guide. Sport Classes: Paralympic cycling is divided into three sport classes:

Handcycle H1-4: There are four different sport classes for handcycle racing and lower numbers indicate a more severe activity limitation. Cyclists in the sport classes H1-3 compete in a reclined position. While athletes competing in the H1 class have a complete loss of trunk and leg function and have limited arm function, e.g. because of spinal-cord injuries, athletes in the H3 class have no leg function but good trunk and arm function. Cyclists in the H4 sport class sit on their knees and can thus use their arms and trunk to accelerate the handcycle. Athletes in this sport class might have leg amputations, paraplegia or mild to moderate athetosis or ataxia.

Tricycle T1-2: Tricycle athletes are divided into two classes, T1 and T2. Due to an impairment affecting their balance and coordination they cannot ride a bicycle. The sport class T1 is allocated to athletes with more significant coordination problems or loss of muscle power than athletes competing in sport classT2.

Bicycle C1-5: Athletes who are able to use a standard bicycle compete in the 5 sport classes C1-5. The sport class profiles include amputations, impaired muscle power or range of motion and also impairments affecting coordination, such as ataxia and athetosis. Sport class C1 is allocated to athletes with the most severe activity limitation, while the sport class C5 is allocated to athletes who meet the minimum disability criteria. For example, cyclists with a double below-the-knee amputation who use a prosthesis are likely to compete in the sport class C3, while an athlete with a below knee amputation and a prosthesis on one leg would compete in the sport class C4.

Tandem TB: Cyclists with visual impairment race on a tandem with a sighted cycler sitting in the front. Cyclists with visual impairment either have a low visual acuity or a visual field restricted to a diameter of 40 degrees.

Equestrian: Included impairment types: physical impairment, visual impairment. More often known as riding, horseback riding (American English) or horse riding (British English) refers to the skill of riding, driving, or vaulting with horses. Sport Classes: Paralympic equestrian is divided into three sport classes:

Grade Ia: Physical impairments Athletes have severe impairments of all limbs and poor trunk control, which usually necessitate the athlete to use a wheelchair in daily life.

Grade Ib: Physical impairments Athletes have either severely reduced trunk control and minimally impaired upper limbs or moderate impairments of the upper and lower limbs and the trunk. Most riders in this class use a wheelchair in daily life.

Grade II: Physical impairments Athletes have a very limited ability in both lower limbs and a good trunk balance, or milder limitations in upper and lower limbs with reduced trunk control. For example, an athlete with a severe impairment in one arm and one leg on opposite sides and good trunk and hip control is likely to compete in Grade II. Some riders in this class use a wheelchair in daily life.

Grade III: Physical and visual impairment Athletes are able to walk, but have a severe impairment in both arms or have no arms, a moderate impairment of all four limbs or short stature. This grade also includes athletes with no sight.

Grade IV: Physical and visual impairment Comprises athletes with impaired range of motion or muscle strength, deficiency on one limb or mild deficiency on two limbs. Moreover, riders with reduced vision or a restricted visual field compete in this grade.

Football: Included impairment types: physical impairment, visual impairment. Consists of adaptations of the sport of association football for athletes with a physical disability. These sports are typically played using International Federation of Association Football (FIFA) rules, with modifications to the field of play, equipment, numbers of players, and other rules as required to make the game suitable for the athletes.

Football 5-a-side is an adaptation of football for athletes with visual impairments including blindness. Sport Classes: Paralympic Football 5-a-side is divided into three sport classes:

B1 - Totally or almost totally blind; from no light perception up to light perception but inability to recognize the shape of a hand.

B2 - Partially sighted; able to recognize the shape of a hand up to a visual acuity of 2/60 or a visual field of less than 5 degrees.

B3 - Partially sighted; visual acuity from 2/60 to 6/60 or visual field from 5 to 20 degrees.

Football 7-a-side is an adaptation of association football for athletes with cerebral palsy and other neurological disorders, including stroke and traumatic brain injury. Sport Classes: Paralympic Football 7-a-side is divided into four sport classes:

C5: Athletes with difficulties when walking and running, but not in standing or when kicking the ball.

C6: Athletes with control and co-ordination problems of their upper limbs, especially when running.

C7: Athletes with hemiplegia.

C8: Minimally disabled athletes; they must meet eligibility criteria and have an obvious impairment that has impact on the sport of football.

Goalball is a team sport designed for blind athletes. Goalball is played by visually impaired athletes and a special rule means there is no need for classification. Participants wear "black out" masks to ensure everyone competes equally.

Judo: Included impairment types: physical impairment, visual impairment. Is an adaptation of the Japanese martial art of judo. Judo is contested by visually impaired athletes only, so there is no specific categorization as competitors are divided by weight in the same way as able-bodied athletes; except with the visual impairment category.

Visual impairment category:

B1: Judoka in this sport class are diagnosed with visual impairment and are either blind or have very low visual acuity. By way of explanation, their level of visual acuity is such that the athlete cannot recognize the letter “E” (15x15cm in size) from a distance of 25cm.

B2: The B2 sport class profile includes athletes with a higher visual acuity than athletes competing in the B1 class, but they are unable to recognize the letter “E” from a distance of 4m. Moreover, athletes with a visual field of less than 10 degrees diameter are eligible for this sport class.

B3: The B3 sport class profile describes the least severe visual impairment eligible for Judo. Eligible athletes either have a restricted visual field of less than 40 degrees diameter or a low visual acuity.

Powerlifting: Included impairment types: physical impairment. Is an adaptation of the sport of powerlifting for athletes with disabilities. The only discipline in Paralympic powerlifting is the bench press. Powerlifting is open to all athletes with a physical disability and is classified by weight alone. Powerlifters competing at the Paralympics have disabilities including paralysis, cerebral palsy and lower limb amputation. Both male and female competitors take part in 10 weight classes.

Rowing: Included impairment types: physical impairment, visual impairment. Is a special category of rowing. Rowing, new for the 2008 Paralympic programme. Sport Classes: Paralympic rowing is divided into four sport classes:

AS: Athletes in sport class AS primarily use their arms and shoulders to accelerate the boat, as they have minimal or no leg and trunk function, which can be caused by spinal cord injuries, for example.

TA: Sport Class TA comprises athletes who can use their arms and trunk when rowing, but are not able to use their legs or a sliding seat when performing the strokes. These athletes typically have good trunk and arm function. For example, athletes with a double around the knee amputation would fit this sport class profile.

LTA-PD: This sport class includes athletes, who can use their legs, trunk and arms to accelerate the boat and can use the sliding seat. Athletes who miss three fingers on one hand or have a foot amputation might be eligible to compete in this class.

LTA-VI B1, B2 and B3: Rowers in this sport class have varying degrees of visual impairment. Athletes in sport class B1 are nearly or completely blind. Athletes in the B3 sport class have the least severe eligible visual impairment. Fairness between the teams: To ensure that races are fair, rowers compete only against rowers in the same sport class. Consequently, there are four different events in adaptive rowing:

LTA Mixed coxed four: Two male and two female rowers from the sport classes LTA-PD and LTAB1/ 2/3 form a team. Due to their physical strength, only two rowers in the team may have a visual impairment and no more than one may have the sport class LTA-VI B3. All athletes with visual impairment are blindfolded during training and competition.

TA Mixed double sculls: One female and one male rower of sport class TA form a team.

AS Women’s single sculls and AS Men’s single sculls: In sport class AS there are separate events for men and women and the athletes compete in single boats.

Sailing: Included impairment types: physical impairment, visual impairment. Is the propulsion of a vehicle and the control of its movement with large (usually fabric) foils called sails. Sport Classes: Paralympic sailing is divided into three sport classes:

Three-Person Keelboat: The sailors are classified with a sport class from 1 to 7, with 7 indicating the least severe and 1 indicating he most severe eligible impairment. For example, a sailor with complete tetraplegia is likely to compete in sport class 1 and a sailor with a single above knee amputation is likely to compete in sport class 7. Moreover, athletes with visual impairment are also classified with the same sport classes. Depending on their visual ability, they compete in sport class 3, 5 or 7, with 7 indicating the highest eligible visual ability. To make sure that no crew has an advantage or disadvantage in the competition due to impairment, each crew is only allowed a maximum of 14 points.

Two-Person Keelboat: One sailor has to be allocated the sport class “TPA” and the other one has to be classified as “TPB.” The sport class TPA includes athletes with more severe impairments, which are equivalent to a sport class 1 or 2 on a Three-Person Keelboat. Examples for impairments included in this sport class profile would be complete quadriplegia or a double above-the-elbow amputation. The sport class TPB means that an athlete only has to meet the minimum impairment criteria for sailing. Athletes of all seven sport classes of the Three- Person Keelboat could compete in the TPB sport class, including athletes with visual impairment.
