Respiratory Muscle Strength in Chronic Stroke Survivors and Its Relation With the 6-Minute Walk Test

OBJECTIVE: To evaluate respiratory muscle strength and six-minute walk test (6MWT) variables in patients with uncontrolled severe asthma (UCSA). METHODS: This was a cross-sectional study involving UCSA patients followed at a university hospital. The patients underwent 6MWT, spirometry, and measurements of respiratory muscle strength, as well as completing the Asthma Control Test (ACT). The Mann-Whitney test was used in order to analyze 6MWT variables, whereas the Kruskal-Wallis test was used to determine whether there was an association between the use of oral corticosteroids and respiratory muscle strength. RESULTS: We included 25 patients. Mean FEV1 was 58.8 ± 21.8% of predicted, and mean ACT score was 14.0 ± 3.9 points. No significant difference was found between the median six-minute walk distance recorded for the UCSA patients and that predicted for healthy Brazilians (512 m and 534 m, respectively; p = 0.14). During the 6MWT, there was no significant drop in SpO2. Mean MIP and MEP were normal (72.9 ± 15.2% and 67.6 ± 22.2%, respectively). Comparing the patients treated with at least four courses of oral corticosteroids per year and those treated with three or fewer, we found no significant differences in MIP (p = 0.15) or MEP (p = 0.45). CONCLUSIONS: Our findings suggest that UCSA patients are similar to normal subjects in terms of 6MWT variables and respiratory muscle strength. The use of oral corticosteroids has no apparent impact on respiratory muscle strength.

Training Protocol

Background: Although the progressive nature of pulmonary hypertension (PH), including the impairment of respiratory muscle function, studies have demonstrated beneficial effects of physical exercise on the functional limitations caused by the disease in this population, being an important ally to the conventional drug therapy. There is no training protocol focused exclusively on respiratory musculature that is performed without supervision, since these patients have low adherence to the rehabilitation programs performed in an outpatient setting. Respiratory muscle training (RMT) improves functional capacity and quality of life (QoL) in patients with chronic diseases such as heart failure and COPD. However, the effects of an unsupervised RMT protocol on PH are not yet known. Objective: To developed an unsupervised, home-based RMT protocol for patients with PH. Methods: A double-blind, controlled, randomized clinical trial to evaluate the effectiveness of this protocol on respiratory muscle strength and endurance, functional capacity, by the six-minute walk test and QoL with the questionnaire The Medical Outcomes Study 36- item Short Form Health Survey (Sf-36) before and after an unsupervised training protocol and performed in a home environment with POWERbreathe. Two groups (IMT and SHAM) will be followed for 12 weeks with training performed 30 minutes daily. Results: We hope the intervention idealized by the protocol may will increase the respiratory muscle strength and endurance, the walk distance in six-minute walk test and QoL. Conclusions: Patients with PH who perform the intervention with inspiratory muscle training protocol may will be increase the respiratory muscle strength, functional capacity and QoL.

Abstract Introduction Patients on hemodialysis (HD) improve functional capacity after physical training. However, little is discussed about these effects in elderly patients, since these are usually excluded of studies, due to their physical disabilities and other deficits. Objective To analyze the effects of aerobic and resistance training in the functional capacity of elderly patients submitted to HD. Methods Studied participants were 15 patients, of both genders, and aged over 60 years. Aerobic and resistance training was carried out during the hemodialysis session, three times per week, during four months. Patients were distributed into control (CG) and experimental (EG) groups. Functional capacity was assessed by six-minute walk (6MW), sit-to-stand (STS) and respiratory muscle strength tests. Results After the physical training, EG presented a significant increase in the distance covered in 6MW (Z = 2.521, p < .012), respiratory muscle strength (inspiratory pressure: Z = 2.533, p < .011; expiratory pressure: Z = 2.536, p < .011); and in number of STS repetitions (2.54; p <.001). Conclusion The training modified the functional capacity of the HD patients, contributing to their rehabilitation.

PURPOSE: This study aimed to investigate the level of physical function, lower body strength, and muscle activation during various types of muscle contraction in participants with and without Parkinson’s disease (PD).METHODS: Twelve participants with PD (mean age=63.17±6.24 years) and 12 age- and sex-matched healthy adults (mean age = 58.67±6.39 years) were recruited. An isokinetic dynamometer was used to measure the length- and velocity-dependent maximum voluntary force and the rate of torque development (RTD) of the knee extensor muscles. Muscle activation of the vastus lateralis (VL), vastus medialis (VM), and rectus femoris (RF) muscles of both legs was examined using surface electromyography. The 6-minute walk test, chair stand test, timed up-and-go test, sit-and-reach test, and back-scratch test were performed to assess physical function.RESULTS: Compared to healthy individuals, participants with PD showed significantly lower maximum voluntary force and RTD (p<.05), performed fewer repetitions in the chair stand test (11.64±1.75 vs. 17.08±2.27, p<.001), were slower in the timed up-andgo test (8.36±1.42 vs. 5.65±1.07, p<.001), and walked shorter distances in the 6-minute walk test (424.17±65.97 vs. 539.47±63.18, p<.001). However, activation of the three different muscles during isometric and isokinetic muscle contraction was not different between participants with and without PD.CONCLUSIONS: Preserved muscle activation and significantly lower muscle strength during various types of muscle contractions may suggest lower muscle strength and efficiency. The lower physical function seen in participants with mild PD could be due to disease and low physical activity-related muscle atrophy rather than lower muscle activation.

Abstract Background Motor impairments caused by stroke result in impaired diaphragmatic and respiratory muscle function, changes in thoracic biomechanics on the hemiparetic side ultimately resulting in decreased efficiency of lung ventilation. This study aimed to examine the efficacy of chest expansion resistance exercise (CERE) on respiratory function, trunk control ability, and balance in patients with chronic stoke. Following a purposive sampling, thirty-five patients with chronic stroke were randomly allocated into two groups, i.e., the experimental group receiving CERE with conventional therapy and the control group receiving conventional therapy alone. Both the groups received therapy four times per week for a period of four weeks (total 16 sessions). Following assessments were done before and after treatment in both the groups: chest expansion ( axillary, nipple, xiphisternal levels) using measure tape, respiratory muscle strength using micro-respiratory pressure meter, trunk control using the Trunk Impairment Scale, and balance using mini-Balance Evaluation Systems Test. Results Both groups had 17 participants each (n = 34, drop-outs = 1) consisting of 12 males and 5 females having a mean age of 56.5 ± 12.98 years and 59.7 ± 10.2 years, respectively. Intra-group analysis showed a statistically significant increase in mean values of chest expansion, respiratory muscle strength, trunk control ability, and balance in the experimental group whereas the control group showed improvement only in trunk control ability and balance. Inter-group comparison revealed a better improvement in all the outcome variables in experimental group compared to the control group. Conclusions Based on these results, this study proved that CERE was more effective in improving respiratory function, trunk control, and balance in patients with chronic stroke.
