ConclusionsThe psychological intervention for cataract patients can improve their visual acuity,quality of life and satisfaction degree with nurse-patient relationship,and it is worthy of wide application.

BACKGROUND:The biomechanical analysis of scoliosis cases is limited,with only independent analysis focusing on the spine or lower limbs,thus lacking a comprehensive evaluation of the multidimensional body.As a result,it becomes challenging to reflect the movement relationship between the trunk and lower limbs during daily activities,which hinders comprehensive clinical treatment guidance. OBJECTIVE:To explore the relationship between different segments of the spine and the kinematics/kinetics of the lower limbs during gait activities by measuring spinal kinematics in scoliosis patients,to provide a comprehensive and multi-level assessment of the biomechanical differences between scoliosis patients and the normal population,consequently offering evidence-based guidance for the prevention and treatment of scoliosis. METHODS:A cross-sectional study was conducted from July 2020 to June 2021 at the Rehabilitation Hospital Affiliated to Fujian University of Traditional Chinese Medicine in Fuzhou University City.A total of 28 scoliosis patients and 28 normal individuals in the same age group were included.Three-dimensional motion capture system was used to capture gait kinematic data at a sampling frequency of 100 Hz.Two force plates(AMTI 400600,sampling frequency 1 500 Hz)were embedded in a 10-meter-long 2.4-meter-wide level ground walkway(with an effective data collection length of 4 m)to collect kinetic data.The differences in spatial-temporal parameters,kinematics,and kinetics of gait between the two groups were compared.Immediately after inclusion,all subjects underwent full spinal X-ray measurements to compare the differences between the scoliosis and normal groups. RESULTS AND CONCLUSION:(1)Patients with scoliosis exhibited reduced relative rotational range of motion between the shoulder and trunk,as well as between the thorax and pelvis,compared to the normal group(P<0.05).However,the rotational range of motion in the pelvis was larger in patients with scoliosis compared to the normal group(P<0.05).(2)Patients with scoliosis showed decreased range of motion in the hip and knee joints,as well as reduced peak torque in hip joint flexion and extension,and lower peak values of ground reaction forces in the concave and convex directions,in comparison to the normal group(P<0.05).(3)Patients with scoliosis demonstrated greater asymmetry indices in knee joint range of motion,relative rotational range of motion between the shoulder and trunk,and between the thorax and pelvis,when compared to the normal group(P<0.05).(4)These findings illustrate a rigid movement pattern among the shoulder,thorax,and pelvis in patients with scoliosis during level walking.There is a reduction in range of motion in the hip and knee joints,as well as decreased peak torque values in hip joint flexion and extension,and ground reaction forces in the concave and convex directions.These characteristics can serve as foundational elements for assessing rehabilitation and developing treatment plans.

OBJECTIVETo evaluate the clinical efficacy of warm-needling moxibustion for knee osteoarthritis (KOA), and to explore its effects on isokinetic strength of lower limb muscle.

METHODSFifty cases of KOA were randomly divided into an observation group (25 cases) and a control group (21 cases), but 4 cases lost contact. The observation group was treated with warm-needling moxibustion at Dubi (ST 35), Neixiyan (EX-LE 4), Xuehai (SP 10), Liangqiu (ST 34), Yinlingquan (SP 9), Yanglingquan (GB 34), Weizhong (BL 40), Heyang (BL 55) and Fengshi (GB 31) for 40 min per treatment. The first 6 treatments were given once a day, and the last 6 treatments were given once every other day. 12 treatments were taken as one course, and totally 3-week treatment was given. No treatment was given in the control group for 3 weeks. The isokinetic strength of extensor muscle and flexor muscle, including the total work, absolute peak torque (aPT) and relative peak torque (rPT), and Western Ontario and McMaster Universities Arthritis Index (WOMAC), and comprehensive efficacy were observed and compared in the two groups.

RESULTSCompared before treatment, the total work, aPT and rPT of the extensor and flexor muscle increased significantly after treatment in the observation group (<0.01,<0.05), but the flextion/extention ratio was lowered (<0.05). In the control group, aPT and rPT of flexor muscle were reduced after treatment (<0.05,<0.01). The total work, aPT and rPT of the extensor muscle in the observation group were higher than those in the control group after treatment (<0.05,<0.01), but the flextion/extention ratio was lowered (<0.05). The item score and total score of WOMAC were reduced in the observation group after treatment (all<0.01), but no significant change was observed in the control group (all>0.05). The pain score, stiffness scores and total score of WOMAC in the observation group were lower than those in the control group (<0.01,<0.05); the score of daily function activities was declined in the observation group, but not significantly different from that in the control group (>0.05). The total effective rate was 88.0% (22/25) in the observation group.

CONCLUSIONSWarm-needling moxibustion could relieve pain, improve function and muscle balance, strengthen extensor and flexor muscle power, especially extensor, which has superior clinical efficacy.

Objective:To quantify the kinematic changes in the gait cycle among youths with chronic, nonspecific low back pain (CNLBP).Methods:A Qualisys 3D optical motion capture system was used to document the gait kinematics of 11 youths with CNLBP and 11 healthy counterparts. Gait profile scores and movement analysis profiles were then calculated.Results:The young CNLBP subjects exhibited gait abnormalities, as reflected by the significant difference of the gait variable the range of motion of the dominant knee between the CNLBP and healthy groups [(5.66±1.83)° vs (3.64±1.13)°]. Gait profile scores and movement analysis profiles are applicable to evaluating them.Conclusions:There manifested gait abnormalities in youth CNLBP patients. Gait profile scores and movement analysis profiles are applicable to evaluating them.

OBJECTIVETo observe the kinetic change that reflects joint loading in different planes during stair climbing in knee osteoarthritis (KOA) after electroacupuncture (EA) by three-dimensional motion analysis, so as to provide reference for its biomechanical mechanism treated with acupuncture.

METHODSForty KOA patients, in accordance with the random number table, were assigned into an observation group and a control group, 20 cases in each one and finally 18 cases completed. Acupoints in the observation group were Neixiyan (EX-LE 4), Dubi (ST 35), Yanglingquan (GB 34), Yinlingquan (SP 9), Xuehai (SP 10), Liangqiu (ST 34) and Zusanli (ST 36); points in the control groups were located about 2 cm next to the above acupoints with shallow acupuncture. EA was connected at Neixiyan (EX-LE 4) and Yinlingquan (SP 9), Liangqiu (ST 34) and Yanglingquan (GB 34). The frequency was 2 Hz with continuous wave in the observation group and there was no current in the control group for the corresponding points. All the treatment was given for 3 weeks, totally 11 times. Climbing stairs gait was measured before and after treatment. Velocities and kinetic parameters during ascending and descending stairs were analyzed, including flexion and extension peak torques of hip, knee, ankle on the vertical plane, external knee adduction moment on the coronal plane.

RESULTSAfter treatment in the observation group, velocities during ascending and descending stairs significantly increased (<0.05,<0.01); maximal ankle plantar flexor moments during ascending and descending stairs and the second peak external knee adduction moment (PEKAM2) during ascending stairs significantly increased (<0.05,<0.01). After treatment in the control group, the first peak external knee adduction moment (PEKAM1) and PEKAM2 during descending stairs were less than those before treatment (<0.05,<0.01). In the observation group, the difference value (DV) of velocity before and after treatment was positively correlated to DV in the torque of ankle plantar flexors during ascending stairs in the observation group (=0.598，<0.01). Excluding the impact of velocity, the DV of the maximal torque of ankle plantar flexors during ascending stairs didn't show difference in the observation group (>0.05).

CONCLUSIONEA can increase the velocities of ascending and descending stairs of KOA patients. It improves the loading capacity of knee joint on both sagittal and coronary planes. But its effect during ascending may be correlated with the increase of velocity. The mechanism of different effects between EA and minimal acupuncture on joint moments is still unclear and warrants further study.

Objective To observe the effects of electro-acupuncture on loading of lower limb joints in patients with knee osteoarthritis (KOA) during stair climbing and explore the related biomechanical mechanism. Methods Forty patients with KOA were randomly assigned, with 20 patients in observation group (electro-acupuncture group, EA group) and 20 patients in control group (superficial acupuncture group, SA group). Finally 18 patients in each group completed the study. In observation group, seven knee acupuncture points were chosen and patients were connected with electro-acupuncture instrument; while in control group, the electro-acupuncture instrument was connected but not electrified after superficial acupuncture at non-acupoint points. The three-dimensional gait analysis system was used to assess the biomechanical characteristics during stair climbing before and after treatment, including peak vertical force (PFz), vertical impulse (IFz) and symmetry index (SI%). Results After 3 weeks of treatment in EA group, PFz of the right foot during stair ascent and PFz of the left foot during stair descent increased (P＜0.05); IFz of both feet during stair ascent and IFz of the right foot during stairs descent significantly decreased (P＜0.05); no significant differences were found in SI% of peak and impulse (P＞0.05). In SA group, only SI of impulse during stairs ascent increased (P＜0.05). There was no significant difference between two groups before and after treatment (P＞0.05). Conclusions Electro-acupuncture can effectively improve the joint load capacity and reduce the dynamic cumulative load of patients w
