Their awareness of the parts of the body makes a pat on the leg or arm an effective command to lift that part of the body.

Different fabrics cut into different shapes can be used for rubbing on the person's skin or with hand-over-hand rubbing.

The ordinary items listed in ACL 1.6 may be held and moved when placed in their hand for a short and measurable period of time.

Habitual lifting of hands and feet may be stimulated by sleeves and pant legs. The garment must be held so that they can see the hole where their hand or foot should go. These habits are probably stored in procedural memories because directing a hand or a foot toward other objects is not expected until ACL 3.0.

The person can acknowledge and respond to verbal commands to move body parts. Carers should use three words or less, which are repeated. The most frequent may be buns up, bum up or butt up. Carers should use a calm clear and firm voice to gain cooperation. The person's response is so slow that patience is a necessity. Hurrying up is not an option because startle and combative reactions are highly likely.

The person is aware of their body in relation to their position in space. The may startle if moved quickly without a word of warning and waiting 20 seconds for the person to take in the information.

They can move their whole arm when cued but using their hands intentionally is limited. The feeling of keeping a limb up against gravity is pleasant for the person for a few seconds.

The ability to lift the hands up against gravity is quite an achievement and is enjoyed by the person.

Roll over and hold still is connected to ACL 1.6; lift and hold still is connected to ACL 1.8.

While in bed, they can lift their buttocks for bridging. During a transfer, they can supply about 50% of the effort to sit up or lie down. While sitting, they can imitate range of motion exercises for their upper extremities.

The difficulty with ACL 1.8 is that the effect of gravity is an internal cue. Careful observation is required to verify their awareness of the effects of gravity on their own body.

Two measures of sustained attention may be possible. One measure is the length of time attention can be sustained to a specific cue. The other is the length of a sensory stimulation session. The session could include several cues / responses. Within ACL 1.8, the session may last five or ten minutes.

The response time is about 20 seconds and attention fades away in less than a minute.

A verbal and / or tactile cue to lift and hold captures attention, which can be sustained with constant cuing.

With head support, the person is able to sit up for 3 to 4 hours and engage in pleasant activities.

Without head support, the person has enough head control to sit up for a few minutes, but the rest of the body requires support.

Nursing care is much easier because the person can bridge, which is lifting and holding their buttocks up.
