Every registry must collect the motor function status with respect to each of the following abilities. These items are intended to be feasible for all registries (both clinician and patient-reported) to collect.

• Hold head up without support: Able to support weight of own head without assistance or resting head against an object.
• Roll onto side: From a supine position, able to roll onto (either left or right) side without assistance.
• Sit without support (WHO): Sits up straight with the head erect for at least 10 seconds. Does not use arms or hands to balance body or support position.
• Crawl on hands and knees (WHO): Alternately moves forward or backward on hands and knees. The stomach does not touch the supporting surface. There are continuous and consecutive movements, at least three in a row.
• Stand with assistance (WHO): Stands in upright position on both feet, holding onto a stable object (e.g. furniture) with both hands without leaning on it. The body does not touch the stable object, and the legs support most of the body weight. Thus stands with assistance for at least 10 seconds.
• Stand without assistance (WHO): Stands in upright position on both feet (not on the toes) with the back straight. The legs support 100% of the body weight. There is no contact with a person or object. Stands alone for at least 10 seconds.
• Walk with assistance (WHO): Upright position with the back straight. Makes sideways or forward steps by holding onto a stable object (e.g. furniture) with one or both hands. One leg moves forward while the other supports part of the body weight. Takes at least 5 steps in this manner.
• Walk without assistance (WHO): Takes at least 5 steps independently in upright position with the back straight. One leg moves forward while the other supports most of the body weight. There is no contact with a person or object.
• Walk 10 metres without assistance: As “Walk without assistance”, but walks in this manner for at least 10 meters.
• Climb stairs: Climbs at least 4 stairs independently. Contact with a railing is permitted but there is no additional help from a person or other object.
• Useful function of hands (RULM): Can use hands to hold pencil or pick up a token or drive a powered chair, use phone key pad. Corresponds to a score of 1 of the RULM entry item.
• Reach overhead in a sitting position (RULM): Can raise both arms simultaneously above head whilst in a sitting position. Corresponds to a score of 5 or 6 on the RULM entry item.
• Raise hands to mouth in a sitting position (RULM): Can raise one or two hands to mouth whilst in a sitting position. Corresponds to a score of 2 on the RULM entry item.

Abilities marked with “WHO” are taken from the WHO Motor Milestones; those marked with “RULM” are contained in the Revised Upper Limb Module.

For each ability, the present and past status of the individual must be collected. Since the type of information to be collected is the same for each ability, this group contains only two records. For every individual, at least one instance of each record must be provided for each of the abilities.
