The Effects of a Motorized Aquatic Treadmill Exercise Program on Muscle Strength, Cardiorespiratory Fitness, and Clinical Function in Subacute Stroke Patients

The aim of this study was to assess whether the effects of a motorized
aquatic treadmill exercise program improve the isometric strength of the knee
muscles, cardiorespiratory fitness, arterial stiffness, motor function, balance,
functional outcomes, and quality of life in subacute stroke patients. DESIGN:
Thirty-two patients were randomly assigned to 4-wk training sessions of either
aquatic therapy (n = 19) or land-based aerobic exercise (n = 18). Isometric
strength was measured using an isokinetic dynamometer. Cardiopulmonary fitness
was evaluated using a symptom-limited exercise tolerance test and by measuring
brachial ankle pulse wave velocity. Moreover, motor function (Fugl-Meyer
Assessment [FMA] and FMA-lower limb [FMA-LL]), balance (Berg Balance Scale
[BBS]), Activities of daily living (Korean version of the Modified Barthel Index
[K-MBI]), and quality of life (EQ-5D index) were examined. RESULTS: There were no
intergroup differences between demographic and clinical characteristics at
baseline (P > 0.05). The results shows significant improvements in peak oxygen
consumption (P = 0.02), maximal isometric strength of the bilateral knee
extensors (P < 0.01) and paretic knee flexors (P = 0.01), FMA (P = 0.03), FMA-LL
(P = 0.01), BBS (P = 0.01), K-MBI (P < 0.01), and EQ-5D index (P = 0.04) after
treatment in the aquatic therapy group. However, only significant improvements in
maximal isometric strength in the knee extensors (P = 0.03) and flexors (P =
0.04) were found within the aquatic therapy group and control group. CONCLUSIONS:
Water-based aerobic exercise performed on a motorized aquatic treadmill had
beneficial effect on isometric muscle strength in the lower limb. TO CLAIM CME
