Relationships of Balance, Gait Performance, and Functional Outcome in Chronic Stroke Patients: A Comparison of Left and Right Lesions

Introduction. This study compared the balance by center of pressure (COP) and its relationship with gait parameters and functional independence in left (LH) and right (RH) chronic stroke patients. Methods. In this cross-sectional study, twenty-one hemiparetic stroke patients were assessed for Functional Independence Measure (FIM), balance with a force platform, and gait in the Motion Analysis Laboratory. Results. The amplitudes of the COP in the anteroposterior and mediolateral directions were similar in both groups. The anteroposterior direction was greater than the mediolateral direction. Only the temporal parameters showed any statistically significant differences. The LH showed a significant correlation between stride length, step length, and gait velocity with COP velocity sway for the healthy and paretic lower limbs. In both groups, the area of COP was significantly correlated with stride length. Motor FIM was significantly correlated with the COP in the LH group. Conclusion. There was no difference in the performance of balance, gait, and functional independence between groups. The correlation of the COP sway area with stride length in both groups can serve as a guideline in the rehabilitation of these patients where training the static balance may reflect the improvement of the stride length.

Bone Loss in Chronic Hemiplegia: A Longitudinal Cohort Study

The purpose of this study was to evaluate hemiplegic stroke patients in terms of long-term changes in bone mineral density and related factors. We conducted a longitudinal cohort study, involving 57 first-stroke patients (40 males) with chronic hemiplegia (for more than 12mo), at a university rehabilitation center in the city of São Paulo, Brazil. Bone loss, body composition, lean mass, and fat mass were evaluated at 2 time points (mean interval, 16mo). Bone loss was significantly greater in paretic forearms than in nonparetic forearms (p=0.001) and in patients having suffered strokes more recently (p=0.015). We found no difference between paretic and nonparetic femurs. Femoral bone loss was significantly greater in patients using anticoagulants or anticonvulsants (p=0.025) and in those with greater spasticity (p=0.040), regardless of the time since stroke. Our results provide additional evidence that hemiplegic stroke patients have progressive bone loss and that such bone loss is more common in the arms than in the legs. Patients with poststroke hemiplegia should be densitometric monitored mainly in paretic arm and treated for bone loss, with attention to the determinants identified in this study.

Unidirectional Expiratory Valve Method to Assess Maximal Inspiratory Pressure in Individuals without Artificial Airway.

Introduction Maximal Inspiratory Pressure (MIP) is considered an effective method to estimate strength of inspiratory muscles, but still leads to false positive diagnosis. Although MIP assessment with unidirectional expiratory valve method has been used in patients undergoing mechanical ventilation, no previous studies investigated the application of this method in subjects without artificial airway. Objectives This study aimed to compare the MIP values assessed by standard method (MIPsta) and by unidirectional expiratory valve method (MIPuni) in subjects with spontaneous breathing without artificial airway. MIPuni reproducibility was also evaluated. Methods This was a crossover design study, and 31 subjects performed MIPsta and MIPuni in a random order. MIPsta measured MIP maintaining negative pressure for at least one second after forceful expiration. MIPuni evaluated MIP using a unidirectional expiratory valve attached to a face mask and was conducted by two evaluators (A and B) at two moments (Tests 1 and 2) to determine interobserver and intraobserver reproducibility of MIP values. Intraclass correlation coefficient (ICC[2,1]) was used to determine intraobserver and interobserver reproducibility. Results The mean values for MIPuni were 14.3% higher (-117.3 ± 24.8 cmH2O) than the mean values for MIPsta (-102.5 ± 23.9 cmH2O) (p<0.001). Interobserver reproducibility assessment showed very high correlation for Test 1 (ICC[2,1] = 0.91), and high correlation for Test 2 (ICC[2,1] = 0.88). The assessment of the intraobserver reproducibility showed high correlation for evaluator A (ICC[2,1] = 0.86) and evaluator B (ICC[2,1] = 0.77). Conclusions MIPuni presented higher values when compared with MIPsta and proved to be reproducible in subjects with spontaneous breathing without artificial airway.

Functional evolution of critically ill patients undergoing an early rehabilitation protocol

Objective Evaluation of the functional outcomes of patients undergoing an early rehabilitation protocol for critically ill patients from admission to discharge from the intensive care unit. Methods A retrospective cross-sectional study was conducted that included 463 adult patients with clinical and/or surgical diagnosis undergoing an early rehabilitation protocol. The overall muscle strength was evaluated at admission to the intensive care unit using the Medical Research Council scale. Patients were allocated to one of four intervention plans according to the Medical Research Council score, the suitability of the plan’s parameters, and the increasing scale of the plan expressing improved functional status. Uncooperative patients were allocated to intervention plans based on their functional status. The overall muscle strength and/or functional status were reevaluated upon discharge from the intensive care unit by comparison between the Intervention Plans upon admission (Planinitial) and discharge (Planfinal). Patients were classified into three groups according to the improvement of their functional status or not: responsive 1 (Planfinal > Planinitial), responsive 2 (Planfinal = Planinitial) and unresponsive (Planfinal < Planinitial). Results In total, 432 (93.3%) of 463 patients undergoing the protocol responded positively to the intervention strategy, showing maintenance and/or improvement of the initial functional status. Clinical patients classified as unresponsive were older (74.3 ± 15.1 years of age; p = 0.03) and had longer lengths of intensive care unit (11.6 ± 14.2 days; p = 0.047) and hospital (34.5 ± 34.1 days; p = 0.002) stays. Conclusion The maintenance and/or improvement of the admission functional status were associated with shorter lengths of intensive care unit and hospital stays. The results suggest that the type of diagnosis, clinical or surgical, fails to define the positive response to an early rehabilitation protocol.

Identification of relevant categories for inpatient physical therapy care using the International Classification of Functioning, Disability and Health: a Brazilian survey

BACKGROUND Hospitalized patients are at risk for the loss of function and impairment. Physical therapists aim to improve functionality and prevent disabilities. The International Classification of Functioning, Disability and Health (ICF) propose a universal language to classify the functionality of patients across different health care settings and over diverse health conditions. OBJECTIVES To identify the International Classification of Functioning, Disability and Health categories that describe most common and relevant patient problems managed by physical therapists in Brazilian hospitals in the acute and post-acute care settings. SUBJECTS The participants were physical therapists who worked in hospitals with a minimum work experience of two years. METHODS A consensus-building, two-round, emailed survey was conducted using the Delphi technique. RESULTS For the development of an ICF short list, 47 physical therapists from the acute care setting and 30 physical therapists from the post-acute care setting responded to the Delphi exercise. Most of the professionals were from the cardiorespiratory physical therapy area. A 80% level of consensus or higher was established for the selection of the categories of the ICF components (Body Functions, Body Structures, Activities and Participation, and Environmental Factors). We obtained two short lists to be used in clinical practice comprising 39 ICF categories for acute care settings and 53 for post-acute care settings. CONCLUSION This study is the first to identify the most relevant aspects for physical therapy in Brazilian hospitals using the ICF framework. Our results can help to promote the adoption of the ICF in physical therapy clinical practice in the hospital setting.

Is the 6-minute pegboard and ring test valid to evaluate upper limb function in hospitalized patients with acute exacerbation of COPD?

Background The 6-minute pegboard and ring test (6-PBRT) is a useful test for assessing the functional capacity of upper limbs in patients with stable COPD. Although 6-PBRT has been validated in stable patients, the possibility of a high floor effect could compromise the validity of the test in the hospital setting. The aim of this study was to verify the convergent validity of 6-PBRT in hospitalized patients with acute exacerbation of COPD (AECOPD). Methods A cross-sectional study was conducted in a tertiary hospital. Patients who were hospitalized due to AECOPD and healthy elderly participants, voluntarily recruited from the community, were considered for inclusion. All participants underwent a 6-PBRT. Isokinetic evaluation to measure the strength and endurance of elbow flexors and extensors, handgrip strength (HGS), spirometry testing, the modified Pulmonary Functional Status Dyspnea Questionnaire (PFSDQ-M), the COPD assessment test (CAT), and symptoms of dyspnea and fatigue were all measured as comparisons for convergent validity. Good convergent validity was considered if >75% of these hypotheses could be confirmed (correlation coefficient>0.50). Results A total of 17 patients with AECOPD (70.9±5.1 years and forced expiratory volume in 1 second [FEV1] of 41.8%±17.9% of predicted) and 11 healthy elderly subjects were included. The HGS showed a significant strong correlation with 6-PBRT performance (r=0.70; p=0.002). The performance in 6-PBRT presented a significant moderate correlation with elbow flexor torque peak (r=0.52; p=0.03) and elbow extensor torque peak (r=0.61; p=0.01). The total muscular work of the 15 isokinetic contractions of the elbow flexor and extensor muscles showed a significant moderate correlation with the performance in 6-PBRT (r=0.59; p=0.01 and r=0.57; p=0.02, respectively). Concerning the endurance of elbow flexors and extensors, there was a significant moderate correlation with 6-PBRT performance (r=−0.50; p=0.04 and r=−0.51; p=0.03, respectively). In relation to the upper-extremity physical activities of daily living (ADLs) assessed by means of PFSDQ-M, there was a significant moderate correlation of 6-PBRT with three domains: influence of dyspnea on ADLs (r=−0.66; p<0.001), influence of fatigue on ADLs (r=−0.60; p=0.01), and change in ADLs in relation to the period before the disease onset (r=−0.51; p=0.03). The CAT was also correlated with 6-PBRT (r=−0.51; p=0.03). Finally, the performance in 6-PBRT showed a significant moderate correlation with the increase in dyspnea (r=−0.63; p=0.01) and a strong correlation with the increase in fatigue of upper limbs (r=−0.76; p<0.001) in patients with AECOPD. Convergent validity was considered adequate, since 81% from 16 predefined hypotheses were confirmed. There was no correlation between 6-PBRT and patients’ height. The performance in 6-PBRT was worse in patients with AECOPD compared to healthy elderly individuals (248.7±63.0 vs 361.6±49.9 number of moved rings; p<0.001). Conclusion The 6-PBRT is valid for the evaluation of functional capacity of upper limbs in hospitalized patients with AECOPD.

Effects of transcutaneous electrical nerve stimulation on chemotherapy-induced peripheral neuropathy symptoms (CIPN): a preliminary case-control study

[Purpose] The aim of this double-blind, randomized and placebo-controlled study is to investigate the effects of Transcutaneous Electrical Nerve Stimulation for reducing the side effects of Chemotherapy-induced Peripheral Neuropathy in cancer patients undergoing chemotherapy with oxaloplatin or paclitaxel. [Subjects and Methods] Twenty-four patients were randomly allocated into two groups: active or placebo stimulation. All patients were assessed for pain, numbness/tingiling, frequency of symptoms, and quality of life. The transcutaneous Electrical Nerve Stimulation device was applied daily with modulating frequencies ranging between 7 Hz and 65 Hz in distal limb regions during three cycles of chemotherapy (45 days). The other stimulation parameters were: pulse duration of 200 μsec, intensity at the highest tolerable level, and increases in intensity when it diminished. [Results] The data showed no difference between active or placebo groups in terms of pain, numbness/tingling, frequency of symptoms or impact on daily life activities. [Conclusion] These results suggest that Transcutaneous Electrical Nerve Stimulation applied in the frequency variation mode was not proven to be effective to improve the symptoms of Chemotherapy-induced Peripheral Neuropathy during chemotherapy cycles. There was no worsening of symptoms in subsequent cycles of the onset of symptoms of the disease.

Ultrasound therapy and transcutaneous electrical neuromuscular stimulation for management of post-mastectomy upper limb lymphedema

This article aims to assess the effect of transcutaneous electrical stimulation or ultrasound therapy in the treatment of post-mastectomy upper limb lymphedema. Method: A systematic literature review was performed from 1980 to 2012 from the MedLine, Cochrane Library, LILACS and SciELO databases. The terms used in the search were (breast neoplasm OR breast cancer OR lymphedema) and (hyperthermia, induced OR diathermy OR ultrasonic therapy OR ultrasound OR transcutaneous electrical nerve stimulation OR TENS). The selections of the studies concerned female patients with post-mastectomy upper limb lymphedema who underwent diathermy by ultrasound therapy and transcutaneous electric nerve stimulation. Only randomized (RCT) and quasi-randomized study designs were included (both Narrow and Broad Therapy). Only studies published in the full paper format were included. After reviewing the 2,158 abstracts resulting from the search, only two papers were selected. Two researchers analyzed the two articles, using the Van Tulder and JADAD scales for quality assessment. Results: Both papers evaluated the use of ultrasound therapy and electric stimulation for treatment of post-mastectomy lymphedema. A total of 132 subjects were included in these two studies, and little improvement was observed in pain reduction or quality of life. Only the study using ultrasound therapy identified a small reduction in lymphedema symptoms; however, evidence supporting the application of this method is lacking. Conclusion: Further studies are needed to evaluate the use of ultrasound therapy or electrotherapy for treatment of post-mastectomy lymphedema and to evaluate the potential effect of these therapies on later development of metastatic disease.
