Effects of an aquatic therapy approach (Halliwick-Therapy) on functional mobility in subacute stroke patients: a randomized controlled trial

Objective: To evaluate the effects of an aquatic physiotherapy method (Halliwick-Therapy) upon mobility in the post-acute phase of stroke rehabilitation. Design: Randomized controlled trial. Setting: Hospital for neurological rehabilitation. Participants: Adult patients after first-ever stroke in post-acute inpatient rehabilitation at least two weeks after the onset of stroke ( n = 30). Interventions: In the Halliwick-Therapy group ( n = 14) the treatment over a period of two weeks included 45 minutes of aquatic therapy three times per week and a conventional physiotherapeutic treatment twice a week. Subjects in the control group ( n = 16) received conventional physiotherapeutic treatment over a period of two weeks five times per week. Outcome measures: The primary outcome variable was postural stability (Berg Balance Scale). Secondary outcome variables were functional reach, functional gait ability and basic functional mobility. Results: Compared to the control group, significantly more subjects in the Halliwick-Therapy group (83.3% versus 46.7%) attained significant improvement of the Berg Balance Scale ( P < 0.05). Improvement of the functional gait ability was significantly higher in the Halliwick-Therapy group (mean (SD) 1.25(0.86)) than in the control group (mean (SD) 0.73 (0.70)) ( P < 0.1). The mean differences of improvements in functional reach and basic functional mobility were not statistically significant between groups. Conclusions: This study indicates that Halliwick-Therapy is safe and well tolerated in stroke patients in post-acute rehabilitation and has positive effects upon some aspects of mobility.
