How low level are we talking? Are the majority no longer able to initiate meaningful movement?
I am the activity director in a ninety bed facility. The majority of my clients are mid to high functioning but the small percent that aren't tend to be difficult to program for.
Balloon ball is the number one success. Punch balls work really good because they don't pop as easy. We get good movement, laughter and increased self esteem from all the cheers and encouragement they get from staff. We do groups with mixed functional levels like balloon volley ball, paddle ball and parachute toss and we play 1:1 around the facility.
Music is another one. 1:1 while holding their hand, sing alongs with lots of the oldies and spiritual songs and mixed functional groups where peers can assist and encourage the others.
The third successful one is person specific. We use pictures of when they were young adults or former tools they once used or crafts they once did, sewing projects etc and visit 1:1. For some we made personal boxes of memorabilia.
We have two activity staff, myself and my assistant. On Monday and Friday around 3:30 in the afternoon when people begin to sundown we each have a 1:1 cart with books, magazines, easy puzzles, newspapers and sensory tools for tactile, olfactory etc., and we go out to visit those people who can't or won't come out into the facility community and our very low functioning residents who can't enjoy larger group activities.
Hope this helps some.
