During the Coronavirus disease (COVID-19) pandemic, millions of people were forced to self-isolate and halt regular exercise and clinical visits. Several studies recently highlighted the impact of the pandemic on people with Parkinson’s disease (PD), including worsening motor symptoms, mood, anxiety, and insomnia [Successful balance telerehabilitation requires the ability to perform both virtual assessment and virtual treatment. Balance is particularly challenging to assess virtually because a thorough and detailed in-person balance assessment typically involves measuring performance across multiple domains of balance (e.g., anticipatory postural adjustment [APA], postural sway, trunk range of motion, and turning) and with enough challenge to evoke imbalance, but this is difficult to carry out safely with virtual visits. Previous studies have demonstrated the feasibility of virtually assessing fall-related measures such as 5 times sit-to-stand [Although telerehabilitation is becoming more common for people with PD, it remains to be seen whether it is feasible and efficacious for improving balance control [Balance telerehabilitation for neurologic patients lacks strong evidence-based trials and it presents unique safety concerns [How an exercise program is delivered is important. We previously compared the Agility Boot Camp (ABC) exercise intervention executed via one-on-one, delivery with the physical therapist in the clinic versus at-home, unsupervised exercises (standard of care) [Another major focus in rehabilitation care is the advancement of using objective measures to quantify movement. Our group [The present trial has three aims: I)
