Equally surprise the authors also failed to discuss this confounder, considering that physical activity/exercise is generally recommended as first line treatment for OA (and since the data is apparently available in the Osteoarthritis Initiative).

(Although I've since stoped using the term subacromial impingement as it's unprecise and misleading.)

TL;DR: Low to moderate evidence suggests that taping might reduce bowstringing of the finger flexor tendons. Moderate evidence suggests that taping has no effect on MVC or muscle activation in uninjured climbers. For other outcomes more studies evaluating the effects of taping are needed.

Then again, when climbing interventions were compared to waitlist or individual interventions, it proved superior - and when it was compared to other group interventions, there were no between group differences - clearly highlighting the importance of group interactions and feelings of belonging.

Hard to say, in general, being part of open supportive community clearly has therapeutic merit -we discuss this confunder of group cohesiveness in discussions-section- but in included trials, the climbing intervention was delivered by medical personnel & exposure to climbing community might be less.

TL;DR: Indoor rock climbing, particularly bouldering (combined with mindfulness exercises), appears to be an effective, clinically meaningful, safe, and sustainable adjunctive intervention for adults with moderate depression.
