BACKGROUND:Three-dimensional (3D) motion analysis system combined with electromyograph cannot only objectively analyze movement function of the upper limb, but also exert an important role in exploring the exercise-related factors and the underlying mechanism.
OBJECTIVE:To explore the influence of movement velocity and target location on kinematics and muscle activity in upper limb reaching.
METHODS:Twelve healthy young adults reached for three different location targets (frontal, ipsilateral and contralateral) at self-selected and fast speeds to with the dominant right hand, respectively. Kinematic parameters and muscle activity were recorded by Vicon 3D motion analysis system and Noraxon wireless electromyograph, synchronously.
RESULTS AND CONCLUSION:Reach path ratio became smal er when moving faster (P<0.001), while mean velocity, peak velocity and the time percentage of peak velocity increased (P<0.001). Posterior deltoid, biceps brachi and triceps brachi activation was higher during fast speed movement (P<0.001). Muscle activation of anterior deltoid was lower in ipsitralateral reaching than contralateral (P=0.001) and frontal reaching (P<0.001), and posterior deltoid was higher than contralateral reaching (P=0.019). Biceps brachi (P=0.039) and triceps brachi (P<0.001) activation was also higher in ipsitralateral reaching than frontal reaching. These results suggest that moving fast can contribute to more muscle activation, high velocity, smooth trajectory and increased movement quality. Posterior deltoid, elbow extension and flexion muscle activation are high in ipsitralateral reaching, while high anterior deltoid activation in contralateral reaching;therefore, target location result in muscle synergies.

Objective To investigate any correlation between walking capacity, center of mass, and pelvic and hemiparetic lower limb motions in stroke survivors. Methods The kinematic variables studied included maximum walking speed, center of mass ( CoM ), pelvic movements and lower-limb movements on the paretic side. These were examined using a three-dimension motion analysis system as thirty-two post-stroke hemiparetic patients walked without aids. Results Average walking capacity was significantly correlated with lateral shifting of the CoM, with paretic limb hip extension, and with deficient knee flexion motions. There was a significant correlation between lateral CoM shifting and paretic limb hip extension and also deficient knee movement. Conclusions Walking capacity after stroke is associated with the lateral shifting of the CoM, paretic limb hip extension and deficient knee flexion. The lateral CoM shifting was associated with paretic limb hip extension and deficient knee movements.

ObjectiveTo evaluate the relationship between the level of thoracic complete spinal cord injury(SCI) and ambulatory function wearing Reciprocating Gait Orthosis(RGO) through three dimentional gait analysis, and to explore the quantitative indicators of reconstructing walking capacity of thoracic complete SCI patients.Methods10 patients with thoracic complete spinal cord injury of lesion level from T4 to T12 who had experienced RGO gait training for at least 3 months. Three dimentional gait analysis system of Vicon Nexus 1.2 was used to test and examine the gait speed, cadence, stride length, pelvic angle of rotation, hip range of motion(ROM), crutch force, angular velocity of hip flexion and extension phases, etc. Pearson's product moment correlation coefficient and Spearman rank correlation coefficient were used to examine the relationship between the level of spinal cord injury and the kinematic and kinetic values.ResultsThe mean cadence and stride length were (37.4±2.15) steps/min and (91.6±9.09) cm. The mean hip ROM, angular velocity of hip flexion and extension phases were (42.57 °±5.43 °), (20.88 °±2.18 °)/s and (124.75 °±9.31 °)/s respectively. The gait speed, stride length, peak crutch force, hip ROM, mean crutch force and angular velocity of hip extension phase all had significant pertinence with the level of spinal cord injury.ConclusionThe limitation of hip ROM and excessive load of upper limbs mainly result in ambulatory disorder in higher thoracic complete SCI patients who should be undertaken some rehabilitation training to reduce excessive physiological load in order to improve their ambulatory capacity.

Nine patients who have preceded total replacement of the hip are treated with early rehabilitational program. The patients were measured with the criteria of Hip Joint Functional Evaluation(HJFE)and Functional independent Measure (FIM). The result shows that early rehabilitational program greatlyadvanced the patients'walking ability and level of ADL.

BACKGROUND:Most stroke patients affected walking dysfunction. Virtual reality-enhanced body weight-supported treadmil training has been proposed as a strategy for gait training of cerebral infarction subjects.
OBJECTIVE:To evaluate the effectiveness of virtual reality-enhanced body weight-supported treadmil training on lower limb motor function in subacute cerebral infarction patients.
METHODS:Twenty cerebral infarction patients (within 3 months of onset) were randomly divided into experiment group (virtual reality-enhanced body weight-supported treadmil training) and control group (conventional physiotherapy). Three-dimensional gait analysis in lower limb motor function was carried out before and after 3-week gait training. Intergroup and intragroup comparisons in the fol owing parameters were done before and after training:walking speed, cadence, step time, single limb support time (%), double limb support time (%), nonparetic swing (%), step length, pace, range of motion in the lower limb, functional ambulation category, Fugl-Meyer Assessment of the lower limbs and Brunel Balance Assessment.
RESULTS AND CONCLUSION:No significant differences in patient’s gender, age, course of disease, affected. side, walking speed, functional ambulation category, Fugl-Meyer Assessment of the lower limbs and Brunel Balance Assessment were detected between the two groups before training (P>0.05). Fugl-Meyer Assessment and functional ambulation category were improved in patients of the two groups after training (P<0.05). The improvement in walking speed, cadence, step time in affected side, step time in healthy side, single limb support time in affected side (%), nonparetic swing (%), pace, step lengths in affected and healthy sides were better in the experimental group than those in the control group.

BACKGROUND:Total hip arthroplasty is known to be a successful surgical procedure to al eviate hip pain and to regain gait ability, but there are many debates on whether patients’ gait could reach a normal level several years later. OBJECTIVE:To investigate spatiotemporal parameter characters of lower extremities in patients during walking in sequela period fol owing unilateral total hip arthroplasty, and to probe into patients’ walking abilities.
METHODS:In accordance with the method of Case Database Data Analysis detected by Motion Reconstruction Laboratory, 14 patients at 5-10 years after total hip arthroplasty served as the experimental group, and 14 matched healthy persons served as the control group. Gait parameters of lower extremities during walking were col ected by Vicon Nexus. Spatiotemporal parameter characters of lower extremities during gait cycle were analyzed by using Polygon.
RESULTS AND CONCLUSION:Compared with the control group, walking speed, cadence, stride length and step length decreased, but double support and opposite foot off increased on both affected and unaffected sides in the experimental group (P<0.05). Both stride time and step time of the operated lower extremities increased (P<0.05). Foot off of non-operated lower extremities increased (P<0.05). There was no significant difference in al spatiotemporal parameters between operated and non-operated lower extremities (P>0.05). The results suggested that gaits of patients showed good gait symmetry at 5-10 years after surgery. However, they do not reach the level that observed in healthy subjects, and walking ability was poorer than normal persons. Systematic rehabilitation training is needed to improve walking ability.

Objective To explore the outcome of body-weight-supported treadmill training on the kinetic data of lower limb in early stage of stroke.Methods Twenty-seven hemiplegic stroke patients at early stage were recruited and randomized to an experimental group(n =15) and a control group (n =12).Both groups were administered with routine neurological interventions.In addition,the control group was treated with conventional physiotherapy and over-ground walking training,while the experimental group was treated with body-weight-supported treadmill training.The speed of the treadmill walking was started at 0.22 m/s and increased to 0.60 ～ 0.80 m/s gradually.The percentage of the body-weight being supported was not more than 30％,the training time was 5 min per session at the beginning and was increased gradually to 20 ～ 40 min.Kinetic parameters were measured by using two force plates (AMT) and six cameras capture svstem (Vicon Nexus),and motor function was evaluated using Fugl-Meyer Assessment (FMA) at baseline and after three-week's therapy.Peak moment of lower limb joints,ground reaction force and motor function were analyzed.Results FMA scores were significantly improved (P ＜ 0.05) in both groups after treatment,but there was no significant differences (P ＜ 0.05) between the two group.Ground reaction force was significantly increased (P ＜ 0.05) after treatment in the experiment group,but not in control group (P ＞ 0.05).It showed that the hip extension moment at the affected side was significantly lower (P ＜ 0.05) in experiment group than in the control group,the ankle joint flexion and extension moment peak were improved to a significantly larger extend in the experimental group (P ＜ 0.05) than in the control group.In addition,the peak flexion and extension moment of the hip-knee joint and peak flexion and extension moment of the knee-ankle joint were also significantly different from those of the control group (P ＜ 0.05).Conclusion Body-weight-supported treadmill training can facilitate motor recovery of paretic extremity by increasing ground reaction force and load support of the affected lower limb,and help normalize the abnormal gait pattern of lower extremity of stroke patients.
