물의 관성 부하를 이용한 동적 안정성 훈련이 퇴행성 무릎 관절염 여성 노인의 계단보행에 미치는 영향

다국어 초록 (Multilingual Abstract)

Purpose: This study examined whether land-based dynamic stability training using a water-filled inertial vest (Aquavest) improves stair ambulation control, pain, and functional mobility in elderly women with degenerative knee osteoarthritis (KOA). Because stair ascent and descent impose different postural control demands, we focused on the leading limb during ascent (anterior–posterior control) and descent (medio–lateral control).
Methods: Sixteen elderly women with radiographic and clinical KOA were randomly assigned to an experimental group (Aquavest training; n = 8) or a control group (fixed-weight vest training; n = 8). Both groups trained twice weekly for 12 weeks. Pain was assessed with the Visual Analogue Scale (VAS), functional mobility with the manual Timed Up and Go (TUG) test, and dynamic balance with center-of-pressure (COP) variables from two force plates embedded in a 3-step mock staircase. Analysis was limited to the entire stance phase of the leading limb (non-dominant limb during ascent; dominant limb during descent). Primary COP outcomes were velocity and root mean square (RMS), with AP/ML displacement range as a secondary measure.
Results: Compared with the control group, the Aquavest group showed greater reductions in VAS scores and TUG time, along with decreased AP velocity and RMS during stair ascent and decreased ML velocity and RMS during stair descent. Secondary AP/ML displacement range tended to decrease only in the experimental group.
Conclusion: Aquavest-based dynamic stability training improved stair-specific COP control, reduced pain, and enhanced functional mobility in elderly women with degenerative KOA, suggesting water-inertial wearables as a practical and safe option for stair gait rehabilitation and fall-risk reduction.
