Recovering after surgery

The rules state “Characters surviving surgery cannot use any skills (including weapon skills) for 15 minutes after their surgery, while they recover.” At first I thought that “weapon skills” here meant weapon calls, but someone pointed out that technically even wielding a weapon or gun at all is a skill. With that in mind the “including weapon skills” seems more likely to be meant as “including wielding any weapon,” but I wanted to make sure: can you swing uncalled weapon hits/block blows during this period, or not?
