Dynamic thigh muscle strength after auditory feedback training of body weight distribution in stroke patients

Background: Non-hemorrhagic stroke patients experience hemiparesis, an improper handling results in joint contractures. Discharge planning combined with a range of motion (ROM) training given to patients and their families are expected to improve muscle strength in patients after returning from the hospital. Aims: This study is to identify the effectiveness of discharge planning in increasing muscle strength. Methods: This is a quasi-experimental study with a pre-posttest design. A total of 34 respondents were selected by cluster random sampling technique, from RAA Soewondo Pati General Hospital of Pati, Central Java, Indonesia. The respondents were divided equally into two groups; an intervention group (N = 17) was given a discharge planning program together with stroke information and range of motion (ROM) training while the control group (N = 17) received a standard discharge planning available in the hospital. Further, Muscle Rating Scale (MRS) was employed to assess the muscle strength on the 2nd, 7th, and 14th day after discharge planning presented to the nonhemorrhagic stroke patients. Results: This present study clearly acknowledges the standard discharge planning program available in the hospital improve the muscle strength of the upper and lower extremity in the nonhemorrhagic stroke patients just 2nd day after the care (pretest), and the significant improvement was observed until the day 14. Moreover, combining the care with ROM training at the intervention group faster the recovery and the muscle strength improved significantly at the 7th day and continue increase at the day 14. Looking to the muscle strength since the 2nd day to the day 14, respectively the muscle strength of upper and lower limb at the control group improved at the point of 0.588 and 0.882, while at the group received the ROM training reached the value of 1.472 and 1.412. Conclusions: The ROM training combined to the current discharge planning program will faster the muscle strength recovery of the nonhemorrhagic stroke patients. This research provide insight how family plays important role to the success in monitoring the rehabilitation and recovery progress.

Purpose: Based on conventional and quantitative magnetic resonance imaging (MRI), texture analysis (TA) has shown encouraging results as a biomarker for tissue structure. Chemical shift encoding-based water–fat MRI (CSE-MRI)-derived proton density fat fraction (PDFF) of thigh muscles has been associated with musculoskeletal, metabolic, and neuromuscular disorders and was demonstrated to predict muscle strength. The purpose of this study was to investigate PDFF-based TA of thigh muscles as a predictor of thigh muscle strength in comparison to mean PDFF. Methods: 30 healthy subjects (age = 30 ± 6 years; 15 females) underwent CSE-MRI of the lumbar spine at 3T, using a six-echo 3D spoiled gradient echo sequence. Quadriceps (EXT) and ischiocrural (FLEX) muscles were segmented to extract mean PDFF and texture features. Muscle flexion and extension strength were measured with an isokinetic dynamometer. Results: Of the eleven extracted texture features, Variance(global) showed the highest significant correlation with extension strength (p < 0.001, R2adj = 0.712), and Correlation showed the highest significant correlation with flexion strength (p = 0.016, R2adj = 0.658). Multivariate linear regression models identified Variance(global) and sex, but not PDFF, as significant predictors of extension strength (R2adj = 0.709; p < 0.001), while mean PDFF, sex, and BMI, but none of the texture features, were identified as significant predictors of flexion strength (R2adj = 0.674; p < 0.001). Conclusions: Prediction of quadriceps muscle strength can be improved beyond mean PDFF by means of TA, indicating the capability to quantify muscular fat infiltration patterns.

AbstractThe present randomized controlled study aims to evaluate whether tourniquet application during total knee arthroplasty (TKA) has an effect on (1) thigh muscle strength (quadriceps and hamstring muscle strength) and (2) clinical outcomes (postoperative knee range of motion [ROM], postoperative pain level, and Knee Society Score [KSS]). The effects of tourniquet application during TKA were investigated in 65 patients randomly allocated to one of two groups: TKA with a tourniquet and TKA without a tourniquet. Patients in both groups were comparable in terms of the demographic and clinical data (p > 0.05 for age, number of patients, sex, radiographic gonarthrosis grade, American Society of Anesthesiologists [ASA] classification, and body mass index [BMI]). All patients in both groups were operated by the same surgeon using one type of prosthesis. Isokinetic muscle strength (peak torque and total work) of knee extensors (quadriceps) and flexors (hamstrings) was measured in Newton meters (Nm) using a CYBEX 350 isokinetic dynamometer (HUMAC/CYBEX 2009, Stoughton, MA). The combined KSS (knee score + function score), visual analog scale (VAS), and knee ROM were measured preoperatively and at 1 and 3 months postoperatively to evaluate clinical outcomes. There were no significant differences between the two groups in preoperative and postoperative values of isokinetic muscle strength (peak torque and total work) and aforementioned clinical outcomes (p < 0.05). The present study has shown that quadriceps strength and clinical outcomes were not improved in the early postoperative period (3 months) when a tourniquet was not used during TKA.
