ABSTRACT
Objective:To explore the effect of the pharyngeal pressure feedback training on pharyngeal constriction in persons with swallowing disorders caused by brainstem lesions.Methods:Twenty patients with disordered swallowing caused by a brainstem lesion were randomly divided into a control group and an intervention group, each of 10. Both groups received routine swallowing training including oral sensorimotor training, neuromuscular stimulation and balloon catheter dilation, while the intervention group was additionally provided with two weeks of pharyngeal pressure feedback training. Before and after the treatment, both groups were evaluated in terms of the peak pressure of superior and inferior pharyngeal constriction, endoscopically and also using the functional oral intake scale.Results:There was no significant difference between the two groups in any measure before the intervention. Afterward, both groups had improved significantly by all of the measurements, but the average peak upper pharyngeal pressure, the average intake scale score and the endoscopy results of the intervention group were all significantly better than the control group′s averages.Conclusions:Pharyngeal pressure feedback training can significantly relieve swallowing disorders caused by brainstem lesions.
ABSTRACT
OBJECTIVE@#To compare the efficacy of scalp acupuncture combined with lower-limb intelligent feedback training and lower-limb intelligent feedback training alone for lower-limb motor dysfunction after stroke.@*METHODS@#A total of 154 patients with lower-limb motor dysfunction after stroke were randomly divided into an observation group (76 cases, 6 cases dropped off) and a control group (78 cases, 8 cases dropped off). The patients in both groups were treated with conventional medication and exercise rehabilitation training. In addition, the patients in the observation group were treated with scalp acupuncture combined with lower-limb intelligent feedback training. The scalp acupuncture was given at upper 1/5 of the anterior oblique line of parietal temporal area and upper 1/5 of the posterior oblique line of parietal temporal area. The patients in the control group were treated with lower-limb intelligent feedback training alone. All the treatment was given once a day, 6 days a week, totaling for 8 weeks. The affected-side lower-limb Brunnstrom stage and modified Ashworth scale (MAS) grade, 6-minute walk test (6MWT), Berg balance scale (BBS) score and modified Barthel index (MBI) score were evaluated before and after treatment in the two groups. The plantar pressure was measured by gait function evaluation system.@*RESULTS@#Compared before treatment, the Brunnstrom stage in the two groups was improved after treatment (@*CONCLUSION@#The scalp acupuncture combined with lower-limb intelligent feedback training could reduce the muscle tension of lower limbs, promote the separation movement mode of lower limbs, improve the plantar pressure distribution, and improve the balance ability and walking ability in stroke patients, and the curative effect is better than lower-limb intelligent feedback training alone.

Background: Patients often need to use their arms to assist with functional activities, but after open heart surgery pushing with the arms is limited to minimize force across the healing sternum. Objectives: The main purposes of this study were to determine: 1) how accurately patients can estimate arm weight bearing with 10 lb or less of force and 2) if feedback training is effective for improving ability to estimate arm force and reduce pectoralis major muscle contraction during functional activities. Materials and Methods: An instrumented walker was used to measure arm force during functional mobility tasks including walker ambulation and sit-stand transfers. Pectoralis major muscle electromyography (EMG) activity was measured simultaneously in study participants (n = 21). After baseline testing, study participants underwent a brief session of visual and auditory concurrent feedback training. Data analyses included t-tests, ANOVA, and Pearson correlations (P<0.05). Results: Results showed that self-selected arm force was greater than 10 lb for all tasks (11.7-19.0 lb) but after feedback training, it was significantly lower (8.3-9.8 lb). During most trials (67%), study participants used more than 12 lb of arm force. Pectoralis major muscle EMG values were less than 10% of maximal voluntary contractions and were reduced (2.7-3.3%) after feedback training. Conclusions: Results indicate that patients may not be able to accurately estimate upper extremity force used during weight bearing activities, and that visual and auditory feedback improves accuracy. Activation of the pectoralis major muscle during arm weight bearing is minimal, suggesting minor force occurs across the sternum. An instrumented walker and feedback training appear to be very clinically useful for patients recovering from open heart surgery.

ResultsThere was no significant difference between groups before treatment in both BBS and Holden Walking Classification (P>0.05). The visual feedback group improved more than the balance board training group (P<0.01). ConclusionThe balancer visual feedback training is more effective on balance function and walking ability in stroke patients with hemiplegia.
ABSTRACT
Objective To study the best method for myoelectric feedback training and evaluate the effectiveness of myoelectric artificial hand. Methods Fourteen cases of upper limb amputees (11 male, 3 female, aged 25?8.69 years, right side 13, left side 3,totally 16 myoelectric artificial hands) were recruited for this study. The biofeedback training process was divided into three steps: basic signal of myoelectric feedback training, visible feedback training, and ADL function training. Results After the training, 16 myoelectric artificial hands could grasp, pinch and rotate wrist, and could perform ADL such as dressing, eating, cleaning. Conclusion To achieve the goal set for the myoelectric artificial hand, emphasis should be on locating the most stronger myoelectric signal of the stump and strengthening the feedback training.
