hiiiii dear
here i will give you some guid lines to add it to your rehab. programm

1-Regardin the shoulder apply electric stimulation for posterion fibers of deltoid + the supraspinatus to reduce the chance of sublaxation and pain

2-Encourage the TURNNING ACTIVITIES as early as possible

3-Focus On stretching of Latissmus dorsi mucsle as it tend to get tight affecting trunk stability and gait pattern

Regarding locking of knee joint i have a point of view here ,, the spastisty have positive feature in locking the knee joint and it will appear sooner ar later . ..But u can stimulate the locking action by:

1-try to apply approximation from knelling Position as it stimulat the locking by quadriceps muscle

2-Also try to teach the patient how to stand from sitting to stimulat the knee locking

3-Apply electric stimulation for the VMO (Vustus Medialis Oblicus) muscle on the medial aspect of thigh

finally you can use the knee orthosis for locking the knee during gait training


I HOPE U GET GOOD RESULT
my regards
THE THERAPIST ('',)
