Effect of simple knee trainer on knee active flexion for hemiplegics after stroke / 中国康复理论与实践

@#Objective To observe the clinical efficacy of simple knee trainer on active knee flexion in patients with hemiplegia after stroke.Methods From March, 2020 to May, 2021, 46 hemiplegics after stroke in Beijing Bo'ai Hospital were randomly divided into control group (n = 23) and experimental group (n = 23). Both groups accepted routine rehabilitation training, and the experimental group accepted knee flexion exercise training in sitting position through the simple knee trainer, for eight weeks. They were measured active knee flexion angle in sitting position and maximum flexion angle in walking before and after training, as well as Holden Functional Ambulation Category (FAC).Results Both active knee flexion angle in sitting position and maximum flexion angle in walking significantly increased in both groups after training (|t| > 6.991, P < 0.001), and increased more in the experimental group than in the control group (t > 2.185, P < 0.05). The grade of FAC also improved in both groups (|Z| > 2.828, P < 0.01), and no significant difference was found between groups (Z = -0.821, P = 0.412).Conclusion The application of simple knee trainer can effectively improve the active range of motion of knee, which may be used in clinic- and community-based rehabilitation.

Magnetic resonance imaging of active, passive and imaginary movement / 中华物理医学与康复杂志

Objective To assess any differences in brain activation during active,passive and imaginary movement of the hands using blood oxygen level-dependent functional magnetic resonance imaging (fMRI),and to provide references for the cortical reorganization in patients with brain injuries.Methods Twenty healthy,righthanded,adult volunteers were studied,fMRI was performed during active,passive and imaginary fist clutching.Whole brain analysis and group analysis were applied to get the voxels,the volume of activation,the peak t-score and its coordinates.Results Active and passive movement both produced significant activation in the contralateral sensorimotor cortex,the contralateral supplementary motor area and the ipsilateral cerebellum.The sensorimotor cortex was the most frequently and most strongly activated brain area.Imaginary movement produced significant bilateral activation in the supplementary motor area.Conclusions Active and passive movement induce similar brain activation patterns.This indicates that passive might replace active movement when observing activation of the brain's cortex during the rehabilitation of patients with hemiplegia.

Active and passive movement of the affected hand after ischemic stroke / 中华物理医学与康复杂志

Objective To study the effects of active and passive movement of the affected hand after ischemic stroke on brain activity patterns using blood oxygenation level-dependent functional magnetic resonance imaging (BOLD-fMRI) and to explore the central mechanism of movement treatment for hand disability.Methods Five pa-tients with subcortical cerebral infarction in Brunnstrom stages 1 to 3 (both upper limb and hand affected) were investigated using BOLD-fMRI during active and passive clenching and relaxing of the affected hand.Statistical parametric mapping software (SPM5) was used to integrate the activity data and display them in one standard brain map.The activated areas were then compared.Results The BOLD-fMRI signals aroused by both active and passive move-ment were enhanced in the contralateral sensorimotor cortex,the contralateral premotor cortex,bilaterally in the sup-plementary motor area and in the bilateral cerebellum.Both movements also activated the ipsilateral sensorimotor cor-tex and premotor cortex,which are not normally activated during such movements in healthy people.The areas were more extensive and the activation was stronger during passive movement.Moreover,the activated brain areas induced by active movement were mainly on the contralateral side,while passive movement induced activation distributed over both hemispheres almost evenly.Conclusions Both active and passive movement significantly activate the brain areas responsible for movement of the affected hand.Both are useful for boosting brain reorganization after stroke.

Functional magnetic resonance imaging of active and passive hand movement / 中华物理医学与康复杂志

Objective To assess differences in brain activation between active and passive movement of the right hand using blood oxygen level-dependent functional magnetic resonance imaging (BOLD-fMRI). Methods Nine healthy adult right handed volunteers were studied. fMRI was performed with active and passive finger-to-finger movement. Results Right hand active and passive movement produced significant activation in the contralateral sensorimotor cortex ( SMC ), the contralateral premotor cortex ( PMC ), bilaterally in the supplementary motor area (SMA) and in the ipsilateral cerebellum. The activated brain areas were centered on the contralateral SMC and PMC and located more forward during active movement than during passive movement. The contralateral SMC was the most strongly and the most frequently activated brain area. The contralateral posterior parietal cortex (PPC) was less relevant to the hand movements. Unlike active movement, passivemovement activated more areas in the posterior central gyrus than in the anterior central gyrus. Conclusions Both active and passive movement significantly activate the brain areas which are responsible for hand movement, but there are some differences in the locations of the cortex areas activated and in the incidence activation except in the contralateral SMC.

Prognostic value and influencing factors of active movement of hemiplegic limbs in patients with acute stroke / 国际脑血管病杂志

Limb rehabilitation is one of the key issues for improving the quality of life in patients with stroke. Studies have demonstrated that the retention and recovery of active movement of hemiplegic limb have predictive value for the prognosis in acute stroke. The responsible lesion sites and rehabilitation training in the acute phase may be an important factor in influencing the recovery of active movement ability of hemiplegie upper limb. However, there is still lack of a large, multi-center study, and further related studies are needed.

Operative Management of Metacarpal and Phalangeal Fractures.

Fractures of metacarpals and phalanges are probably the most common fractures in the skeletal system and are often neglected as minor injuries. Most of the fractures are treated conservatively but some form of fixation is often indicated in unstable fractures, intra-articular fractures, open fractures and multiple fractures. Various implants ranging from K-wires to mini-plates are used. A retrospective analysis of 50 cases of metacarpal and phalangeal fractures treated by different methods over a period of one year was undertaken. The study showed that right hand was more commonly involved. Most common mechanism of injury was fall and second ray was most commonly involved. Most common fracture pattern was transverse and K-wires were frequently used as mode of fixation followed by mini-plates. The patients were followed up at regular intervals and union was achieved in 98% of fractures. From our study we would emphasize that operative management of metacarpal and phalangeal fractures has definitely an advantage over the closed methods of treatment especially in displaced, unstable, comminuted, intraarticular, open and multiple fractures. Operative management of hand fractures should be undertaken only if a definite indication exists. Indiscriminate use of it should be avoided. The operative management of metacarpal and phalangeal fractures results in accurate reduction of the fracture and joints should be mobilised early following fixation to prevent stiffness of the fingers and regain the desired range of motion at the joint.

Effective analysis of active movement treatment on prolapse of lumber intervertebral disc / 中国康复理论与实践

@#ObjectiveTo study the necessity of treating prolapse of lumbar intervertebral disc by active movement treatment. Methods68 patients with prolapse of lumbar intervertebral disc were divided into the group of active movement treatment (31 cases) and the control group (37 cases). One year later, the recurrence rate and F wave motor nerve conduction velocity of two groups were compared. ResultsThere is a lower recurrence rate (P<0.05) and a faster F wave motor nerve conduction velocity (P<0.01) in the group of active movement treatment compared with the control group. F wave motor nerve conduction velocity of the group of active movement treatment is also faster than that of 1 year ago (P<0.001). Conclusions It is necessary for patients with prolapse of lumbar intervertebral disc doing active movement.
