This study examined strength training, combined with acupuncture for their effects on balance ability, ankle motion perception, and muscle strength on chronic ankle instability among college students.Methods: Forty-six chronic ankle instability college students were randomly divided into the experimental group (n = 24, strength training + acupuncture) and control group (n = 22, strength training) for an 8-week intervention.For the results at eight weeks compared with the baseline, experimental group: CAI Tool (CAIT) score, ankle dorsiflexion, plantar flex and eversion peak torque (60°/s) and plantar flex peak torque (180°/s) increased by 13.7%, 39.4%, 13.7%, 14.2% and 12.3%, respectively. Dorsiflexion, plantar flexion, inversion and eversion kinesthetic sensation test angle decreased by 17.4%, 20.6%, 15.0% and 17.2%, respectively. Anterior-posterior and medial lateral displacement, anteriorposterior and medial lateral velocity decreased by 28.9%, 31.6%, 33.3% and 12.4%, respectively. Anterior-posterior and medial lateral displacement, anterior-posterior and medial lateral mean velocity decreased by 28.9%, 31.6%, 33.3% and 12.4%, respectively. Control group: CAIT score and the ankle dorsiflexion peak torque (60°/s) increased by 13.8% and 17.9%, respectively. Inversion kinesthetic sensation test angle decreased by 15.2%, whereas anterior-posterior and medial lateral displacement, and anterior-posterior and medial lateral mean velocity decreased by 17.1%, 29.4%, 12.3% and 16.8%, respectively. 2) For the comparison between the groups after eight weeks, the ankle dorsiflexion and plantar flex peak torque (60°/s) in the experimental group was greater than that in control group. Ankle plantar flex kinesthetic sensation test angle, the anterior-posterior displacement and anterior-posterior mean velocity experimental group were lower than those in control group.: Acupuncture treatment in conjunction with muscle strength training can further improve the balance ability of anterior-posterior, ankle dorsiflexion and plantar flex strength and plantar flex motion perception in chronic ankle instability participants.
