Abstract
Purpose Retrospective analysis of the effect of portable 3D gait analysis as an innovative evaluation method in the treatment with MTT on chronic ankle instability patient. Methods From January 1, 2019, to December 31, 2019, 56 cases of chronic ankle instability (CAI) were extracted from the medical record system of Shenzhen Longhua District Central Hospital. All the patients of 56 cases accepted the medical training therapy (MTT). As outcome parameters, the alterations of the Cumberland ankle instability tool (CAIT), foot and ankle ability measure (FAAM), were used before the treatment and after treatment; meanwhile, the portable apparatus 3D gait analysis was used to measure the gait parameters. Conclusion The results showed only ankle angle parameters Y-axis, maximum dorsiflexion during support period (°) had a significant difference, and the p value is 0.039. Meanwhile, the CAIT, FAAM, and most 3D gait analysis data had no significant difference. This particular statistical difference shows that CAI can be measured scientifically and objectively, although most measurement parameters have no change. These results make further reveal that the CAI patients are suffering with dynamic abnormality of ankle motion angle; this also provides us with a measurable and systematic evaluation reference plan for CAI treatment in the future.
Highlights
Ankle sprain is one of the most common musculoskeletal injuries in physical activities
Patients with ankle sprain will suffer from decreased ankle stability and recurrent sprain several months and years after the initial ankle injury, which is the characteristic of chronic ankle instability (CAI) [1]
foot and ankle ability measure (FAAM) consists of two subscales, among which 21 items of the FAAM-ADL scale are related to activities of daily living, and 8 items of the FAAM-sport scale are related to sports
Summary
Ankle sprain is one of the most common musculoskeletal injuries in physical activities. Patients with ankle sprain will suffer from decreased ankle stability and recurrent sprain several months and years after the initial ankle injury, which is the characteristic of chronic ankle instability (CAI) [1]. About 40% of the patients with first-time ankle sprain developed CAI symptoms during the 12-month follow-up, repeated sprains caused by CAI can lead to injuries of soft tissues such as ligaments and tendons of the ankle joint, and severe ankle sprains may induce ankle osteoarthritis [2]. The main nonsurgical intervention methods of rehabilitation medicine for CAI are exercise therapy, ankle protectors, intramuscular patches, etc. Medical training therapy (MTT) is a comprehensive medical sports rehabilitation technology, which is mainly used in sports injuries, postoperative rehabilitation, bone and joint diseases, limb motor dysfunction, pain, and other fields. Our group retrospectively analyzed the medical records of MTT of CAI, in order to further evaluate its clinical efficacy
