CP4 (classification)

CP4 is a disability sport classification specific to cerebral palsy. In many sports, it is grouped inside other classifications to allow people with cerebral palsy to compete against people with other different disabilities but the same level of functionality. Compared lower number CP classes, they have fewer issues with head movement and trunk function. They tend to use wheelchairs on a daily basis though they may be ambulant with the use of assistive devices.

Sports that CP4 athletes are eligible to participate in include athletics, cycling, skiing, slalom, swimming, wheelchair tennis, wheelchair fencing, wheelchair curling, wheelchair basketball, table tennis, sledge hockey, shooting, sailing, rowing, powerlifting, para-equestrian, race running and archery. In some of these sports, different classification systems or names for CP4 are used. When they attend a classifying event, they go with their wheelchair to avoid being put into an ambulatory class.

Cerebral Palsy-International Sports and Recreation Association (CP-ISRA) defined this class in January 2005 as, "Diplegic - Moderate to Severe involvement. Good functional strength with minimal limitation or control problems noted in upper limbs and trunk. Lower Extremities-Moderate to severe involvement in both legs Spasticity Grade 4 to 3 usually rendering them non-functional for ambulation over long distances without the use of assistive devices. A wheelchair is usually the choice for sport. Trunk-Spasticity grade 2 to 1. Minimal limitation of trunk movements when wheeling and throwing. In some athletes fatigue can increase spasticity which can be overcome with proper positioning. When standing, poor balance is obvious even using assistive devices. Upper Extremities-The upper limbs often show normal functional strength. Minimal limitation of range of movement may be present but a close to normal follow through and propulsion is observed when throwing or wheeling."

On a daily basis, CP4 sportspeople in this class are likely to use a wheelchair. Some may be ambulant with the use of assistive devices. They have minimal control problems in upper limbs and torso, and good upper body strength. Head movement and trunk function differentiate this class from CP3. Lack of symmetry in arm movement are another major difference between the two classes, with CP3 competitors having less symmetry.

In athletics events, CP4 competitors participate in T34/F34 classes. In some cases, CP4 athletes may be classified as F54, F55 or F56. Events that may be on the program for CP4 competitors include the club, discus throw, shot put and javelin. While they may be able to walk with assistance, competitors throw from a fixed seated position.
