One article was a review study that looked at active video games for patients with chronic pulmonary diseases - yes a very specific niche which in the end only had 6 articles included in the review.
The other article was a pilot study for patients with Parkinson's disease and the exergaming group did improve their walking gait speed after using Microsoft Kinect.

It's been a while since I've updated my list of studies but you can always check My Diiigo Group - Exergames which has a more up to date list of studies I find.
