Biofeedback Training for Partial Weight Bearing in Patients After Total Hip Arthroplasty

Pataky Z, De León Rodriguez D, Golay A, Assal M, Assal J-P, Hauert C-A. Biofeedback training for partial weight bearing in patients after total hip arthroplasty.

Objective

To evaluate a new biofeedback training method based on visual delivery of information in patients after total hip arthroplasty (THA).

Design

Intervention study with prepost design.

Setting

Hospitalized care in a university referral center.

Participants

Patients (N=11) (age 56.1±9.0y) shortly after THA.

Intervention

A mobile system has been used for biofeedback training with the predefined partial weight bearing (PWB) threshold of 20kg. After the learning period, 4 retention tests, consisting of 3 successive walking cycles without feedback, were recorded for each patient: (1) acquisition test, (2) early retention test (after 30min), (3) the day after, and (4) after 2 days.

Main Outcome Measure

The pressure error and the maximum pressure force at each step before and after biofeedback training.

Results

A significant difference of pressure errors between the beginning and the end of the learning period has been measured (42.5±22.5N vs 3.7±11.4N, P<.001). However, there was no difference between the beginning of the learning period and different retention tests (after 30 minutes, after 1 day, after 2 days). In terms of maximal pressure force, there was a difference between the beginning and the end of learning (251N vs 195N, P<.05). The retention tests did not show significant differences compared with the baseline values.

Conclusions

THA patients were able to use the defined PWB during a short period of time and shortly after stopping the training; both the pressure errors and the maximal pressure force attended the values before training. These results confirm the difficulties to achieve PWB in patients after THA.     

产前宣教对产妇盆底肌力影响及康复疗效观察

目的探讨产前宣教对产妇盆底肌力影响以及电刺激联合生物反馈治疗的临床效果。方法选取产后42d来本院进行产后检查的妇女300例,产前进行盆底肌康复方法宣教的为宣教组。未宣教的为对照组,每组各150例。均给予个体化的电刺激及生物反馈治疗,治疗前后进行盆底肌肉压力检测,评价分析两组的治疗效果。结果产后42 d宣教组的阴道静息压、盆底收缩压及Ⅰ类肌纤维持续收缩压、Ⅱ类肌纤维的快速收缩压均明显高于对照组（P〈0.05）。经电刺激联合生物反馈治疗后,两组各项检测指标较治疗前均有显著提高,但检测指标两组间差异均无统计学意义。结论产前宣教对产后妇女盆底肌恢复有促进作用;两组产妇经电刺激联合生物反馈治疗后盆底肌功能均有显著提高。     

Functional Benefits of Dysphagia Therapy Using Adjunctive sEMG Biofeedback

This article describes a retrospective analysis of functional outcome, time in therapy, and cost per unit of functional change in patients who received therapy for pharyngeal dysphagia. Twenty-five patients presenting dysphagia following stroke and 20 patients with dysphagia following treatment for head/neck cancer completed a systematic therapy program supplemented with surface electromyographic (sEMG) biofeedback. Eighty-seven percent (39/45) of all patients increased their functional oral intake of food/liquid including 92% of stroke patients and 80% of head/neck cancer patients. Patients with dysphagia following stroke demonstrated greater improvement than those in the head/neck cancer group. Patients in the stroke group completed more therapy sessions thus increasing the total cost of therapy, but they made more functional progress resulting in lower costs per unit of functional change than patients in the head/neck cancer group. Limitations of this study are described in reference to implications for future clinical research on the efficacy of this therapy approach.     

Combined biofeedback, physiotherapy and electrostimulation for fecal incontinence

Different outcomes are reported in the literature following pelvic floor rehabilitation for fecal incontinence, possibly due to the type of procedure employed, whether biofeedback or physiotherapy or electrostimulation. The aim of the present study is to analyze the results achieved in a group of patients treated with a combination of the three procedures. Thirty-two patients (24 females) affected by fecal incontinence underwent a course of combined rehabilitation (CR); 23 of them had anal surgery prior to CR, for rectal mucosal prolapse and hemorrhoids in most cases. Eighteen had anal manometry before and after CR. Sixteen underwent anal ultrasound prior to treatment. Patients were taught perineal exercises, biofeedback was either sensory or electromyographic, and electrostimulation was performed with a 10–20 MHz endoanal probe. Twenty-seven patients were available for follow-up. The mean incontinence score improved from 4.0±0.8 to 2.1±1.7 (mean±sd) (p<0.001); 19 patients (70%) were satisfied after CR, and 11 (44%) were fully continent. Post-treatment manometry showed an increased amplitude of squeeze pressure in 50% of the cases, whereas 61% had an increase in duration, but only 27% of them had a positive clinical outcome. Rectal evacuation thresholds improved in 55% of the cases and 86% of them had a corresponding positive clinical outcome. At ultrasound, 6 patients showed intact anal sphincters and had a positive outcome following CR. Pelvic floor rehabilitation seems to be effective for the management of fecal incontinence when carried out combining different types of procedures. No significant correlation was found between manometric and clinical response to the treatment. An increase of rectal sensation may be responsible for the clinical improvement.

Rehabilitation of Fecal Incontinence After Sphincter-Saving Surgery for Rectal Cancer: Encouraging Results

Purpose  Some patients, having undergone sphincter-saving operations for rectal cancer, may suffer from fecal incontinence. This study was designed to evaluate the results of rehabilitative treatment in patients with fecal incontinence after sphincter-saving operations and to identify the negative factors that influence therapeutic success. Methods  Between January 2000 and June 2007, 88 incontinent patients (54 women; age range, 47–73 years; 69 had received a low anterior rectal resection; 19 a straight coloanal anastomosis) were included in the study. After a preliminary clinical evaluation, including the Wexner Incontinence Scale score, anorectal manometry was performed. All 88 patients underwent rehabilitative treatment according to the “multimodal rehabilitative program” for fecal incontinence. At the end of program, all 88 patients were reassessed by means of a clinical evaluation and anorectal manometry; their results were compared with the clinical and manometric data from ten healthy control subjects. Postrehabilitative Wexner Incontinence Scale scores were used for an arbitrary schedule of patients divided into three classes: Class I, good (score ≤3); Class II, fair (score >3 to ≤6); Class III, poor (score >6). Results  After rehabilitation, there was a significant improvement in the overall mean Wexner Incontinence Scale score (P < 0.03) for both surgical operation types (low anterior rectal resection: P < 0.05; coloanal anastomosis: P < 0.02). Only 21 patients (23.8 percent) were symptom-free, and 37 (42 percent) were considered Class III. A significant postrehabilitative direct correlation was found between: 1) Wexner Incontinence Scale score and degree of genital relaxation (rρ _s 0.78; P < 0.001); 2) Wexner Incontinence Scale score and irradiation (rρ _s 0.72; P < 0.01); and 3) Wexner Incontinence Scale score and pelvic (rρ _s 0.65; P < 0.01) or anal surgery (rρ _s 0.68; P < 0.01). No significant differences were found between prerehabilitative and postrehabilitative anal pressures in low anterior rectal resection and coloanal anastomosis patients. Conclusions  After rehabilitation, some patients become symptom-free, many patients show an improvement in the Wexner Incontinence Scale score, and others exhibit the highest grades of fecal incontinence. Genital relaxation, radiotherapy, and previous pelvic, and/or anal surgery are impeding factors to rehabilitative success.
