Labuschagne was twice caught behind in near-identical fashion off Broad in the first Ashes Test, playing at balls well outside off stump for a first-ball duck and 13.
His struggles came as Steve Smith also failed twice in the Edgbaston win, the pair's overall contribution of 35 their lowest in a game in which they have both batted twice.
The duo returned to training on Saturday and batted for close to two hours ahead of the start of the second Test at Lord's on Wednesday, in a session initially meant for reserve players.
Labuschagne, in particular, looked much more settled at the crease, after he was guilty of shuffling across in last week's dismissals to Broad.
"What happened in the first Test, I hadn't seen that (before)," batting coach Michael Di Venuto said.
"And it certainly didn't happen the week before at The Oval (in the World Test Championship final).
"Whatever it was, hopefully it was brief and he can get back to normal this week.
"It was pretty much normal (in training on Saturday). And that is all we have seen in the nets in the build-up as well.
"It can be a bit strange, sometimes things happen in the game. He nicked two balls he normally leaves quite regularly. Hopefully, he bounces back this week."
Labuschagne caused a brief scare at training when he wore a side-arm throw-down to the finger after being battered regularly in the Test Championship final.
However, he was able to keep batting on Saturday after being inspected by team medical staff.
Di Venuto said it was likely Smith and Labuschagne would have trained regardless of their low scores, joking the two had probably got bored of shadow-batting in their rooms.
But he was confident big changes were not necessary for the 29-year-old.
"He can probably leave a couple of balls on 12th-stump line, that would be nice," Di Venuto said.
"Marnus is always working on his game. You have all seen him train before, he is meticulous in how he goes about his preparation.
"He is always fidgeting around with different things technically. That is all pretty normal for Marn.
"He has a few other reasons why he thinks he played at the ball which he thinks he has fixed up. As we saw today, hopefully he is back on track."
Di Venuto said he had been buoyed by the batting of David Warner, who has shown glimpses of promise in four innings on the tour after arriving as the man under most pressure.
"He is a little bit back more into the Davey we know. Moving into the ball, lots of energy at the crease, looking to attack," Di Venuto said.
"Some really good signs there for him to potentially have success around the corner."
