Ai Chi in guideline

The Dutch Clinical Practice Guideline for Physical Therapy in patients with stroke (2014) has included a paragraph on hydrotherapy/aquatic therapy, mentioning in particular Halliwick and Ai Chi.


Stating that there is level 1 evidence for chronic stroke patients that hydrotherapy increases muscle strength of the paretic leg of patients. The guideline development team recommends considering aquatic therapy to increase muscle strength. This may involve aerobic training, functional gait training, or exercises using the Halliwick and Ai Chi methods.


Note: The recommendation is based on literature till 2012, including a publication from Noh at al in Clinical Rehabilitation, and from Lambeck & Gamper , Lambeck & Bommer about Halliwick Aquatic Therapy (HAT) and Clinical Ai Chi (CAC) in Comprehensive Aquatic Therapy. The guideline development team expects a need for an update within 2 years in view of the increasing amount of publications, which also holds true for HAT and CAC. Since 2012 at least 15 moderate to high level studies have been published about HAT or CAC in various patient groups.
