I just finished intense rounds of rehab:
Continued home therapy includes: writing some each day, reading a page of anything aloud each day while concentrating on my articulation and breathing....
Continued home therapy includes: leg exercises with theraband, standing/sitting/walking... but, also to continue with the Orthopedic Physical Therapist and try and get my hip/pelvis/skeletal issues resolved.
