Effects of Unstable Exercise Using the Inertial Load of Water on Lower Extremity Kinematics and Center of Pressure During Stair Ambulation in Middle-Aged Women with Degenerative Knee Arthritis
Stair ambulation requires precise lower extremity control and postural stability. Middle-aged women with degenerative knee arthritis (DKA) are at an increased risk of falls, yet the effects of unstable load training on their postural stability remain underexplored.

| description | Stair ambulation requires precise lower extremity control and postural stability. Middle-aged women with degenerative knee arthritis (DKA) are at an increased risk of falls, yet the effects of unstable load training on their postural stability remain underexplored. This study investigated the effects of a 10-week Aqua Vest-based unstable load training program on postural stability and pain during stair ambulation in middle-aged women with DKA. Thirty participants were randomly assigned to an exercise group (EG) or a control group (CG), with 15 participants in each group. The EG completed a 10-week Aqua Vest training program, while the CG received no intervention. Pre- and post-assessments included spatiotemporal parameters, lower extremity kinematics, and center of pressure (CoP) trajectories during stair descent, as well as knee pain evaluated by a visual analog scale (VAS). After training, the EG demonstrated significant improvements in spatiotemporal and kinematic parameters, reduced ML displacement, lower VAS scores, as well as significant changes in AP CoP parameters. These findings suggest that Aqua Vest-based unstable load training may enhance ML postural stability and alleviate pain in DKA patients, potentially contributing to enhanced balance function and improved stair ambulation safety. |
