Background: Hyperopia is a common blurred vision phenomenon that affects postural control in gait; however, current research has focused on the alteration and correction of hyperopia’s physiological characteristics, ignoring the effect of hyperopia on gait kinematic characteristics. The effect of hyperopia on the basic form of movement walking is a worthy concern.Objective: To investigate the gait kinematic characteristics of male college students with varying degrees of visual acuity (normal vision, hyperopia 150°, and hyperopia 450°), as well as to provide a theoretical foundation for the effect of visual acuity on gait and fall risk reduction.Methods: Twenty-two male college students with normal visual acuity were chosen. Their vision was tested using a standard visual acuity logarithm table at normal and with 150° and 450° concave lenses. Gait kinematic data were collected under normal vision and hyperopic conditions using the PN3 Pro advanced inertial motion capture system and Axis Studio application program.Results and conclusion: 1. The change of center of gravity in Pre-double support was smaller than normal vision; Late-single support and Late-swing was larger than normal vision; 2. The percentage of the double-leg support decreased; the percentage of the single-leg support and the Late-swing increased; 3. For the joints’ range of motion, Trunk flexion and extension range of motion in Pre-single support, Late-double support and Pre-swing smaller than normal visual acuity, and Late-swing larger than normal; hip internal abduction and adduction and internal and external rotation are larger than normal vision in Late-single support; knee and ankle in abduction and adduction direction are larger than normal vision in the swing stage; hip flexion and extension, internal external rotation are larger than normal vision in the swing stage. Hyperopic interventions have an impact on the kinematic characteristics of gait in male college students, mainly in terms of altered balance, increased instability, increased difficulty in maintaining trunk stability, and increased risk of injury.

Objective: To study the correlation between dynamic balance ability and lower limb muscle strength of university students. Methods: 50 students of Zunyi Medical University (23 boys and 27 girls) were selected as the subjects. The dynamic balance ability of university students was tested by the YBT test system. Isokinetic muscle strength tester tests knee flexion and extension muscle strength under different angular velocity conditions. Results: 1) At different angular velocities, there was a moderate positive correlation between knee flexion and extension muscle strength and YBT reaching all directions. Only when the angular velocity was set to 200° / s, there was a low positive correlation between knee flexion muscle strength and the front side of the YBT test. 2) There is a more significant correlation between the maximum distance of each direction of dynamic balance and the peak torque of knee extensor than that of flexor. Research conclusions: For university students, there is a significant indigenous correlation between the directions of YBT arrival, and the correlation between the posterolateral and the posterolateral is stronger. The stronger the lower limb muscle strength is, the better the dynamic balance ability is, and the correlation between dynamic ability and knee extensor muscle strength is higher, which may be related to the fact that knee flexion control balance can more effectively activate knee extensor muscle group. University students generally have bilateral asymmetry of the lower limbs.

Objective: To explore the therapeutic effect of acupuncture combined with joint mobilization in the treatment of periarthritis of the shoulder. Methods: According to the random number table method, 46 patients with periarthritis of the shoulder were randomly divided into two groups, with 23 patients in each group. Acupuncture combined with joint mobilization (combination group) and acupuncture alone (control group) were used respectively. The visual analogue scale (VAS), range of motion (ROM), and efficacy were evaluated before treatment, 4 weeks after treatment, and 8 weeks after treatment in each group. The therapeutic effect, pain, and changes in shoulder joint function were compared between the two groups. Results: After 4 weeks of treatment, the VAS scores of patients in both groups were lower than before treatment and the combination group improved better than the control group (P<0.05); the ROM scores of patients in both groups were higher than before treatment and the combination group scored higher than the control group in the forward flexion, back extension and abduction directions (P<0.05); after 8 weeks of treatment, the VAS scores of patients in both groups were lower than before treatment and 4 weeks of treatment and the combination group improved better than the control group (P<0.05); the ROM scores of patients in both groups were higher than those before and at 4 weeks of treatment, and the scores in all directions in the combination group were higher than those in the control group (P<0.05). Conclusion: Acupuncture combined with joint mobilization can better alleviate the pain of patients with periarthritis of the shoulder, and can also more effectively improve the limitation of shoulder joint activity and improve its function
