The study comprised 20 postoperative ACLR patients in a pilot randomized controlled trial. Participants were divided into 2 groups: an aquatic therapy group (n\u2009=\u200910) and a land-based rehabilitation group (n\u2009=\u200910). Both rehabilitation programs were tailored to individual patient needs. Gait parameters were assessed using a high-speed camera before and after the intervention, while muscle tone and stiffness were measured using MyotonPRO. The study findings reveal a significant difference in step length symmetry between the 2 groups postintervention. Within-group analysis showcased noteworthy improvements in the aquatic therapy group, including enhanced single-support phase duration symmetry, reduced vastus lateralis muscle tone on the affected side, and enhanced hamstring muscle tone on the affected side. Conversely, the land-based rehabilitation group demonstrated significant increases in stiffness solely within the affected vastus lateralis. The study suggests aquatic therapy as a viable postoperative option following ACLR. While land-based rehabilitation has its benefits, aquatic therapy shows superior effectiveness in normalizing gait symmetry and restoring muscle properties.<\/jats:p>","DOI":"10.1123\/jsr.2024-0128","type":"journal-article","created":{"date-parts":[[2025,7,23]],"date-time":"2025-07-23T16:01:50Z","timestamp":1753286510000},"page":"207-216","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Aquatic Therapy on Gait Symmetry and Muscle Properties Following Anterior Cruciate Ligament Reconstruction: A Pilot Randomized Controlled Trial"],"prefix":"10.1123","volume":"35","author":[{"given":"Zekun","family":"Liu","sequence":"first","affiliation":[{"name":"School of Sports Medicine and Rehabilitation, Beijing Sport University, Beijing, BJ, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Sports Medicine and Rehabilitation, Beijing Sport University, Beijing, BJ, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuyuan","family":"Yan","sequence":"additional","affiliation":[{"name":"School of Sports Medicine and Rehabilitation, Beijing Sport University, Beijing, BJ, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chi","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Biomedical Sciences, Beijing City University, Beijing, BJ, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donghui","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Intelligent Rehabilitation, Beijing Noitom Technology Ltd, Beijing, BJ, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ting","family":"Zhang","sequence":"additional","affiliation":[{"name":"International Aquatic Therapy Association of China, Beijing, BJ, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiang","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, United Family Women\u2019s & Children\u2019s Hospital, Beijing, BJ, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Ultrasound, Peking University Third Hospital, Beijing, BJ, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ligang","family":"Cui","sequence":"additional","affiliation":[{"name":"Department of Ultrasound, Peking University Third Hospital, Beijing, BJ, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shilun","family":"Hou","sequence":"additional","affiliation":[{"name":"School of Sports Medicine and Rehabilitation, Beijing Sport University, Beijing, BJ, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-0053-3343","authenticated-orcid":true,"given":"Lin","family":"Song","sequence":"additional","affiliation":[{"name":"School of Sports Medicine and Rehabilitation, Beijing Sport University, Beijing, BJ, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"12","key":"r1","series-title":"Am J Sports Med","doi-asserted-by":"publisher","first-page":"2805","DOI":"10.1177\/0363546513502309","article-title":"Patient-reported knee function, quality of life, and activity level after bilateral anterior cruciate ligament injuries","volume":"41","author":"F\u00e4ltstr\u00f6m A","year":"2013","unstructured":"F\u00e4ltstr\u00f6m A, H\u00e4gglund M, Kvist J.
