Partnered Rhythmic Rehabilitation in Prodromal Alzheimer's Disease

Partnered Rhythmic Rehabilitation (PRR) is moderate intensity, cognitively-engaging social dance that targets postural control systems. PRR involves learning complex stepping patterns and fosters tactile communication of motor goals between partners, enhancing social interaction's effect on cognition. Class sizes will consist of 10 or fewer pairs of participants with pAD and partners to maximize safety. Participants will engage in partnering exercises on how to interpret motor goals through touch, exercises to develop understanding of temporal relationship of movement to music, novel step introduction, connecting previously learned and novel step elements. Classes include practicing previously-learned steps, a 20-minute standing warm-up, and partnering and rhythmic enhancement exercises.

WALK sessions consist of 10 minutes of warm-up, and evaluation/tips for practicing safe walking form mechanics (i.e., head up, shoulders relaxed, abdominals engaged, heel strike, roll and toe off; keep natural stride length, and speed up cadence if increased speed is desired), 55 minutes of walking with breaks, and 20 minutes of balance and stretching. WALK will take place in small groups with research assistants and trained family members and/or caregivers to control for social effects/contact of intervention. Participants of similar walking abilities will be 'buddied' with research assistants and trained physical therapy students who will act as group backmarkers, although participants will lead the pace. WALK participants will keep walking logs documenting their progress. WALK is expected to expend 3 metabolic equivalents (METs), like that of PRR.
