There a...As one of the clinical manifestations in patients with hemiplegia after stroke,most of the patients with foot drop suffer from gait disturbance and balance dysfunction, generally accompanied by strephenopodia. There are relatively few researches on the balance ability of patients with foot drop worldwide,while the balance ability will directly affect the walking ability for recovery,so the research is significant in the rehabilitation of foot drop. In the experiment,the Cordura material ankle-foot orthosis (AFO),one of the world leading technology products,is chosen as the experimental equipment because of its well-known durability and strength. The experiment studied the balance performance of patients with foot drop before and after wearing Cordura material AFO. The Berg scale was evaluated to discuss the effect of the orthosis on balance ability in patients with foot drop. It has been found that the wearing equipment BBS scores were significantly improved. There were significant differences comparing with the control group( P<0.05).But in the course of treatment the Berg balance scale (BBS) scores reduced individually,mainly in terms of leg flexibility.展开更多

Methods: Based on the ancient Chinese Daoyin technique, a six-step method was developed including: 1) motion imagination and imitation;2) mental and breathing regulation;3) target point determination;4) motion percussion;5) motion persistence;6) relaxation. Sixty drop-foot patients who suffered from hemiparesis after a stroke were randomly divided into the experimental group and the control group. Functional evaluation including Fugl-Meyer assessment score, Lovett manual muscle test (MMT), active range of motion of the ankle joint and electromyography were performed before and after the training course. The data were analyzed using the statistical software SPSS 12.0. Results: The differences between the two groups were significant. The effectiveness of the six-step group was significantly better than the effectiveness of the control group. Conclusion: The six-step method of the Chinese Daoyin technique is an effective rehabilitation training method for drop-foot in stroke patients with hemiparesis.展开更多

The onset of foot-drop could not be detected until symptoms could be observed visually, patient falling or patient experiencing painful gait issues and expensive medical tests. This research showed that by utilizing the plantar-pressure characteristics of DPN drop-foot gait, a set of index could be developed for the severity of DPN.展开更多

Poor recovery of this nerve after repair or decompression gives great importance to tendon transfer in these situations. Material and Methods: This study was conducted in Neurosurgery Department of Mansoura University from 2015 to 2018 on twenty-six patients (16 males and 10 females). Their age ranged from 6 - 58 years. All of them presented with persistent foot drop at least for one year after injury with no signs of improvement clinically or in electrophysiological studies. All patients underwent tibialis posterior tendon transfer through the interosseous membrane to the tendons of the leg anterior compartment. All of them were put in a plaster cast for four weeks postoperative. A physiotherapeutic program was applied for all patients as preoperative preparation and postoperative rehabilitation. Results: Twenty-two patients showed satisfactory results, three patients fair improvement and one patient no improvement. Two patients had wound infection and there was no mortality in this study. Conclusion:?Tendon transfer is an effective valid solution to be considered in the management of foot drop in these patients.展开更多

Therefore, in this randomized controlled trial, we explored the safety and efficacy of two concentrations and two doses of BTXA in the treatment of spastic toot after stroke to optimize this treatment in these patients. Eligible patients (n = 104) were randomized into four groups. The triceps surae and tibialis posterior on the affected side were injected with BTXA at one of two doses (200 U or 400 U) and two concentrations (50 U/mL or 100 U/mL). 2he following assessments were conducted before as well as 4 days and 1, 2, 4, and 12 weeks after treatment: spasticity, assessed using the modified Ashworth scale; basic functional mobility, assessed using a timed up and go test; pace, assessed using a 10-meter timed walking test; and the ability to walk, assessed using Holden's graded scale and a visual analog scale. The reported results are based on the 89 patients that completed the study. We found significant differences for the two doses and concentrations of BTXA to improve the ability of patients to walk independently, with the high-dose/low-concentration combination providing the best effect. Onset and duration of the ameliorating effects of BTXA were 4-7 days and 12 weeks, respectively. Thus, BTXA effectively treated foot spasms after stroke at an optimal dose of 400 U and concentration of 50 U/mL.展开更多
