young girl with unusual muscular condition showing improvment

we met a young girl who cannot walk normally due to a rare muscular condition where she lacks strength and coordination. We prayed one day and invited the mother to bring her to our meeting. Last week she came and we got to pray for the girl for a long time. We just got the report that she is able to do things that she couldn't do before - like walk up and down stairs without assistance! Needless to say, the mother is bringing her daughter back for more prayer!
