Perhaps you should try some spelling variations:
motor improvement » motor impairment (Expand search), motor movements (Expand search)
decreases disease » diseases disease (Expand search), decreases adipose (Expand search), decreases breast (Expand search)
decrease motor » decreases motor (Expand search), decreases mtor (Expand search), increase motor (Expand search)
toc decreases » c decreases (Expand search), oic decreases (Expand search), co2 decreases (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease _ decrease motor improvement ) OR ( decrease toc decreases disease after ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease motor improvement ) OR ( decrease toc decreases disease after ))*.
