After my diagnosis 6 year ago. Ì steered clear of meds altogether for 5 year focusing on natural interventions. Probably the most beneficial for my balance, stiffness and meditative calming was tai chi and qi gong.
This study shows others benefit also

However, for the first time in 6 years, last week, my instructor showed me tai chi walking.
Although it might seem simple , if correctly followed it's useful for improving gait and balance as well as focusing the mind on movement and weight shifting.
Im lucky to have a teacher guiding me through it but I found this detailed YouTube video should you wish to try at home.
