PMID 27942145WHAT IT FOUND
Eight weeks of proprioceptive training on one leg improved the untrained leg's position sense and single-leg balance in healthy adults.
The study did not test injured patients.
Key findings
01Training the dominant leg only significantly reduced repositioning error and stability indices compared with the control group.
02The training group also significantly reduced repositioning error and stability indices after training compared with its own pre-training values, while the control group did not change significantly.
03In the training group, mean repositioning error was 4.8 degrees before training and 2.8 degrees after training, and the control group's post-training mean was 4.1 degrees.

What it does not show
Participants were healthy subjects aged 18 to 30, not patients with injury or surgery. The assessor knew which group each participant was in, and the same person trained and measured the participants. The paper does not report how many participants completed the 8-week program. Outcomes were measured before and immediately after 8 weeks, not at a later follow-up. Activity level was not homogeneous among participants. Participant motivation may have influenced assessments, although the assessor used verbal encouragement.
The easy way to misread this
Do not conclude that this training improves balance in injured patients. It was tested only in healthy adults, and outcomes were measured immediately after 8 weeks.
