Systematic Review of Postural Assessment in Individuals With Obstructive Respiratory Conditions: MEASUREMENT AND CLINICAL ASSOCIATIONS

Jaw and neck muscle activity during chewing and craniocervical dysfunction index in children, adolescents, and adults with and without cystic fibrosis: a comparative analysis

OBJECTIVE

To compare masticatory muscle activity between people with cystic fibrosis (pwCF) and healthy controls and to verify whether craniocervical dysfunction is associated with the presence of CF.

METHODS

Fifty-six participants were assessed and divided into pwCF and healthy control (HC) groups, each one composed of 13 children and adolescents at 9 (SD 3) years old and 15 adults at 25 (SD 6) years old. Craniocervical Dysfunction Index assessed symptoms of dysfunction and cervical spine mobility. Electromyography was used to evaluate the jaw and neck muscle activity during chewing.

RESULTS

Muscle activity during chewing was not statistically different between groups. Prevalence of craniocervical dysfunction was 75% for pwCF vs 64% for healthy controls. Individuals with CF are 1.53 [1.260, 1.870] times more likely to have reduced cervical mobility compared to healthy controls (p = 0.000).

CONCLUSION

These results reinforce the need for musculoskeletal disorders treatment in the management of pwCF.

Gait and functional balance in non-CF bronchiectasis

BACKGROUND

The decline in ambulatory activities and negative alterations in gait characteristics may impair balance and increase fall risk in obstructive lung diseases. Few studies have evaluated balance and gait parameters in individuals with bronchiectasis.

PURPOSE

This study aimed to compare the gait parameters and functional balance in individuals with non-cystic fibrosis (CF) bronchiectasis and healthy subjects.

METHODS

This cross-sectional and retrospective study analyzed data from 22 individuals with non-CF bronchiectasis and 32 healthy controls recorded between July 2019 and July 2020. Functional balance was assessed using the Timed Up and Go (TUG) test. Gait parameters were evaluated using the Biodex Gait Trainer. Step cycle (s), gait speed (m/s), the number of steps per minute, and ambulation index were measured for 6 min.

Results The TUG time (s) was significantly longer (p = .019, effect size = 0.66), and gait speed (m/s) (p ˂ 0.001, effect size = 2.47), step cycle (s) (p ˂ 0.001, effect size = 2.23), and ambulation index (p ˂ 0.001, effect size = 2.56) were significantly reduced in individuals with non-CF bronchiectasis compared with healthy controls.

CONCLUSION

Non-CF bronchiectasis is related to unfavorable changes in gait characteristics, such as slower gait speed and the decreased average step cycle. In addition, impairment in functional balance and mobility exists in a small percentage of adults with non-CF bronchiectasis. In comprehensive pulmonary rehabilitation, balance and gait evaluations should be included to prevent falls in adults with non-CF bronchiectasis.

Investigating balance, gait, and physical function in people who have undergone thoracic surgery for a diagnosis of lung cancer: A mixed-methods study

Objectives

Symptoms associated with lung cancer and thoracic surgery might increase fall risk. We aimed to investigate: 1) balance, gait and functional status in people post-thoracic surgery compared to healthy controls; 2) perceptions of balance, gait and functional status.

Methods

Recruitment targeted older adults (≥50 years) who had undergone thoracic surgery for a diagnosis of lung cancer in the previous 3 months, and healthy age-matched controls. Dynamic and static balance, gait velocity, knee-extension strength and physical activity levels were assessed using the BESTest, Kistler force plate, GAITRite system, Biodex System 3 and CHAMPS questionnaire, respectively. Two-part semi-structured interviews were conducted post-surgery.

Results

Individuals post-surgery (n = 15) had worse dynamic balance and gait, and lower levels of moderate/vigorous physical activity (MVPA) (all p<0.05) versus healthy controls (n = 15). Strength did not differ between groups (p > 0.05). No associations between BESTest and strength or physical activity existed post-surgery (p > 0.05). Three themes were identified: 1) Symptoms affect daily activities; 2) Functional assessments alter perceptions of balance ability and 3) Open to supervised rehabilitation.

Conclusion

Balance, gait and MVPA are impaired post-thoracic surgery, yet balance was not viewed to be important in enabling activities of daily living. However, supervised rehabilitation was considered acceptable.

Deviations of body functions and structure, activity limitations, and participation restrictions of the International Classification of Functioning, Disability, and Health model in children with cystic fibrosis and non-cystic fibrosis bronchiectasis

BACKGROUND

To the best of our knowledge, there is no study in the literature investigating the extrapulmonary outcomes of children with non-cystic fibrosis (CF) bronchiectasis and CF under the framework of the International Classification of Functioning, Disability, and Health (ICF) model. The purpose of the present study is to evaluate the children with CF and non-CF bronchiectasis using the ICF model.

MATERIALS AND METHODS

Children with CF, non-CF bronchiectasis, and healthy counterparts were evaluated (20 participants in each group) according to the ICF items in domain b (body functions), domain s (body structures), and domain d (activities and participation). The pulmonary functions, respiratory and peripheral muscle strength tests, and posture analysis were carried out for domain b. For domain d, however, the Glittre-activities of daily living test and Pediatric Outcome Data Collection were used.

RESULTS

Muscle strength of shoulder abductors and hip extensors in children with CF was significantly lower than healthy children and adolescents (P < .05). The severity of lateral and posterior postural abnormalities in children with CF and non-CF bronchiectasis was higher than those of healthy children (P < .05). Among the patient groups, global function, sports/physical function, expectations, transfers/basic mobility, and pain/comfort were the most affected participation dimensions (P < .05).

CONCLUSIONS

This study highlights the need for comprehensive up-to-date evaluation methods according to the ICF model for understanding rehabilitation requirements in CF and non-CF bronchiectasis in different age groups.

Videogames in the Treatment of Obstructive Respiratory Diseases: A Systematic Review

Introduction: Millions of people suffer from obstructive respiratory conditions globally. Including videogames in rehabilitation programs can be an interesting alternative to traditional programs or a complementary activity. Objective: To explore the use of videogames in the treatment of patients with obstructive respiratory diseases. Methods: A systematic literature search was performed to identify randomized clinical trials evaluating the effects of videogames on health outcomes in patients with respiratory obstructive diseases. The following databases were searched: PubMed, Web of Science, ScienceDirect, and Scopus. The methodological quality of the studies included was assessed with the Downs and Black quality assessment method. Results: Nine articles were included, of which three used videogames as physical training methods and managed to improve exercise capacity, strength, quality of life, and symptoms. The remaining six articles used videogames to educate patients about the disease and showed slight improvements in knowledge of the disease and use of medication. Conclusion: The results of this review show that videogames are a very useful complementary therapy. They can contribute to enhance rehabilitation programs, as they improve exercise capacity, muscle strength, quality of life, severity, control, and knowledge of the disease. Videogames should be supervised by a professional so that programs can be tailored to patients, proposing different activities in the game and controlling the correct performance, and generating an increase in adherence to treatment.

Postural abnormalities in phenotypes of chronic obstructive pulmonary disease

BACKGROUND

Few studies have demonstrated postural abnormalities in patients with chronic obstructive pulmonary disease - when compared with healthy individuals. However, none of these studies have compared postural abnormalities in different phenotypes of chronic obstructive pulmonary disease.

OBJECTIVE

To compare the thoracic posture between two phenotypes of chronic obstructive pulmonary disease (emphysema and chronic bronchitis) with healthy individuals.

METHODS

Forty individuals with chronic obstructive pulmonary disease (20 with chronic bronchitis, 67±3.5 years, 20 with emphysema, 67.7±4 years) and 20 age-matched healthy individuals (67.3±3.9 years) underwent postural assessment which was performed using photogrammetric measurements of head protraction, shoulder protraction, thoracic kyphosis angle, coronal shoulder angle, and scapular elevation.

RESULTS

Significant differences were found amongst the groups in protraction of head (emphysema vs. chronic bronchitis, mean difference=7.63°, 95% confidence interval [CI]=2.10, 13.15°; emphysema vs. healthy, 7.91°, 95% CI=2.38, 13.43°), protraction of shoulder (emphysema vs. healthy, 13.69°, 95% CI=6.96, 20.43°; chronic bronchitis vs. healthy, 8.11°, 95% CI=1.38, 14.85°), thoracic kyphosis (emphysema vs. healthy, -11.59°, 95% CI=-17.26, -5.92°; chronic bronchitis vs. healthy, -6.75°, 95% CI=-12.41, -1.08°), coronal shoulder angle (emphysema vs. chronic bronchitis, 1.01°, 95% CI=.22, 1.80°; emphysema vs. healthy, 1.59°, 95% CI=.80, 2.38°) and scapular elevation (emphysema vs. chronic bronchitis, =.74cm, 95% CI=.34, 1.15cm; emphysema vs. healthy, .99cm, 95% CI=.59, 1.40cm).

CONCLUSION

People with emphysema show greater degree of postural malalignments in terms of head and shoulder protraction, thoracic kyphosis, symmetry of shoulders and scapular elevation than patients with chronic bronchitis and age-matched healthy individuals. These observations emphasize the importance of postural assessment in individuals with chronic obstructive pulmonary disease, particularly if they are emphysematous.

The Role of Manual Therapy in Patients with COPD

Chronic obstructive pulmonary disease (COPD) is a respiratory condition associated with altered chest wall mechanics and musculoskeletal changes. In this narrative review, we describe the underlying musculoskeletal abnormalities in COPD, the reasons for applying manual therapy techniques, their method of application and clinical effects. A variety of manual therapy techniques have been applied in individuals with COPD, including soft tissue therapy, spinal and joint manipulation and mobilisation, and diaphragmatic release techniques. These have been prescribed in isolation and in conjunction with other treatments, including exercise therapy. When applied in isolation, transient benefits in respiratory rate, heart rate and symptoms have been reported. Combined with exercise therapy, including within pulmonary rehabilitation, benefits and their corresponding clinical relevance have been mixed, the extent to which may be dependent on the type of technique applied. The current practical considerations of applying these techniques, including intense therapist–patient contact and the unclear effects in the long term, may limit the broad use of manual therapy in the COPD population. Further high quality research, with adequate sample sizes, that identifies the characteristic features of those with COPD who will most benefit, the optimal choice of treatment approach and the longevity of effects of manual therapy is required.

Effect of backpack carrying on forced vital capacity in cystic fibrosis: A randomized crossover-controlled trial

BACKGROUND

Backpack carrying impacts lung function in healthy children but the effect in children with cystic fibrosis (CF) is unknown.

METHODS

Three backpack positions were tested: no backpack (NB), a 12.5% body-weight backpack carried bilaterally (BB) or unilaterally (UB), at rest and during a 10 minute walk. Primary outcome was forced vital capacity (FVC). Secondary outcomes included comparison of cardio-respiratory variables within and between groups.

RESULTS

Nine children with CF (13.3±2.6 years; FEV1 66±22%) and 18 healthy children (13.8±1.8 years; FEV1 107±30%) were included. FVC was reduced with UB compared to NB (68.5±23.3% vs 72.1±24.3%, p = 0.024) in children with CF. FEV1, MIP and MEP decreased more with UB in children with CF than in healthy peers. Increases in VO2, VCO2 and minute ventilation with UB were greater in the CF group during walking.

CONCLUSIONS

Unilateral backpack wearing affects FVC in children with CF and requires greater cardio-respiratory adjustments compared to healthy peers.

The involvement of musculoskeletal system and its influence on postural stability in children and young adults with cystic fibrosis

Background

Cystic fibrosis (CF) affects the musculoskeletal system via a multifactorial pathway that includes vitamin D deficiency and involvement of respiratory muscles such as intercostals due to recurrent upper and lower respiratory tract infections. Eventual result is the deterioration of musculoskeletal health and posture in CF patients. Postural stability is directly affected by posture and can be compromised in every musculoskeletal problem. The aim of this study is to evaluate musculoskeletal system and postural stability in patients with CF.

Methods

Patients with CF over six years of age and age and sex-matched control groups were included in the study. Cobb angle and thoracic kyphosis angles were measured on the spine radiographs. Both patients and control group were examined with pediatric gait, arms, legs and spine scale (pGALS). They also were evaluated with a NeuroCom Balance Master for their postural stability.

Results

Fifty-one patients with CF and 94 healthy controls participated in the study. In results of the pGALS examination, CF group had significantly more pathological findings than the control group in lower extremity appearance and movement (p = 0.006 and p = 0.01) and spine appearance and movement (p = 0.001 and p = 0.022) domains. The tandem walking speed was significantly higher in controls with a mean of 24.45 ± 7.79 while it was 20.47 ± 6.95 in the CF group (p = 0.03). Various limits of stability parameters also showed significant differences. Medium correlations were found between musculoskeletal examination and postural stability parameters.

Conclusion

In patients with CF, a systematic but simple musculoskeletal examination can detect pathologies, which are more frequent than the normal population. These pathologies show a medium correlation with the involvement of postural stability.
