Posture and balance control in patients with acromegaly: Results of a cross-sectional study
Gait & Posture, 2014
Acromegaly is a chronic debilitating disease that presents with multiple systemic manifestations, including changes in body composition, joint abnormalities, muscular impairment and visual disturbances. This study aimed to assess posture and body balance in acromegalic patients and to establish the correlation between these measures. Twenty-eight acromegalic patients and a similar number of control subjects matched for sex, age, weight, height and body mass index underwent postural evaluation using the photogrammetry and measurement of balance using the stabilometry in two tasks: feet apart, eyes open and feet together, eyes closed. In comparison with the control group, the acromegalic group presented postural deviations in lateral views in the vertical alignment of the trunk (P = 0.001 for the right side and P = 0.021 for the left), the hip angle (P = 0001 for the right side and P = 0.016 for the left side) and horizontal alignment of the pelvis (P = 0.017 for the right and P < 0.001 for the left side). Compared with healthy subjects, the acromegalic patients presented displacement of the centre of pressure in both the anterior-posterior direction and the medial-lateral direction in both evaluated tasks. We observed significant correlations between balance measures and the following posture evaluation variables: distance between the lower limbs, horizontal alignment of the head and vertical alignment of the head. Our results suggest that posture and balance need to be evaluated for acromegalic patients in clinical practice, as there are significant postural imbalances and deviations in these patients.
Static and dynamic balances in acromegaly and impact of exercise on balance
2018
Glis paper reports the results of a study of productivity change in Kenyan agriculture. The data span the period from Kenyan independence in 1964 to 1989. Until now, no estimates of productivity for agriculture in Kenya have been available. Both multi-factor and labour productivity measures were constructed. Laspeyres indexing procedures were used. Our results indicate that while total production and input use have grown in the sector, productivity has stagnated through the period. Recent years have witnessed declining productivity. Attempts to use Cline's model to explain variations in productivity were unsuccessful. Coefficients of research and extension expenditures, education and weather variables were found to be statistically insignificant when these variables were regressed on productivity.

Purpose] This study compared patients having active acromegaly with those having controlled acromegaly in terms of peripheral muscle strength, body composition, and functional capacity. We also examined the associations between these measures. [Methods] A total of 14 patients with active acromegaly, 12 patients with controlled acromegaly, and 12 healthy controls were subjected to isometric dynamometry, surface electromyography, electrical bioimpedance, and a six-minute walk test.

The six-minute walk test (6MWT) is increasingly being used as an important tool for analyzing functional capacity in patients with multisystem disorders. The aim of this study was to evaluate the effect of body composition, peripheral muscle function, and pulmonary function on the six-minute walk distance (6MWD) in acromegalic patients. [Subjects and Methods] Thirty-two patients with active acromegaly, with a mean age of 48.6 ± 12.1 years, underwent an evaluation of body composition using electrical bioimpedance, isometric dynamometry with surface electromyography, tests of pulmonary function, and the 6MWT. [Results] The mean ± SD values for the 6MWD, fat-free mass (FFM), and maximal expiratory pressure (MEP) were 65.5 ± 11.7% predicted, 55.1 ± 10.6 kg, and 55.2 ± 16.8% predicted, respectively. There was a significant correlation between the 6MWD and the following parameters: the angle of the linear regression line obtained using the values of the median frequency electromyography signal over time during the fatigability test for the vastus medialis muscle (MDF, r=0.65), FFM (r=0.62), MEP (r=0.60), height (2) /resistance index (r=0.52), resistance (r=−0.50), and forced expiratory volume in 1 second (r=0.50). Multivariate analysis showed that MDF, FFM, and MEP were independent predictors of the 6MWD (R 2 =0.52). [Conclusion] The fatigability of the peripheral muscles, FFM, and MEP are the primary determinants of the 6MWD in acromegalics.
Evaluation of Human Body Balance: A Review of Clinical and Simple Field Tests of Balance
Brain and Neurological Disorders
The purpose of this article is to highlight the main evaluation techniques used in body balance. We discussed movement regulation, biomechanical, metric characteristics, validity, objectivity, repeatability, sensitivity for the practical use of every assessment. We also identify critical research-based reviews, Pros and cons of the body balance tests. The techniques are widely used in rehabilitation, sports medicine, and laboratory. The article closes with a summary of human balance and proposals for future research work.
Effect of Aerobic and Anaerobic Exercise on Static and Dynamic Balance in Physiotherapy Students
International Journal of Scientific Research in Science and Technology, 2019
The aim of the study is to evaluate and compare the effects of aerobic and anaerobic exercise on static and dynamic balance in healthy physiotherapy students. 30 subjects were selected and were divided into two groups (n= 15). Assessment was done by stork standing balance test and modified BASS test for static and dynamic balance before the experiment. After completion of the initial balance measurement, group-A subjects were given aerobic exercise which included 15 minutes of Modified Bruce protocol and group-B subjects were given 3 forms of aerobic exercises for 2 weeks alternate days. Post this exercise protocol, balance was reassessed on day 15. Significant changes were found in the pre and post exercise balance scores. Both static and dynamic balance showed improvement but static balance was better improved after aerobic exercise than anaerobic exercise and dynamic balance was better improved after anaerobic exercise than aereobic exercise. Also Aerobic and Anaerobic Exercise showed more improvement in static balance than dynamic balance. Thus, this study concludes that both aerobic and anaerobic exercise showed statistically significant improvement in the static and dynamic balance.
Posturographic analysis of balance control in patients with haemophilic arthropathy
Haemophilia, 2008
Musculoskeletal disorders in haemophiliacs represent the highest percentage of lesions, giving rise to haemophilic arthropathy (HA) which predominantly affects lower limbs, influencing postural control, standing and walking. Leading a sedentary lifestyle seems to influence strength and muscular resistance in haemophiliacs which, in turn, are related to articular stability and the prevention of articular degenerative processes. The objective of this work was to study alterations in balance to subsequently evaluate the appropriate therapeutics and how this influences the development of arthropathy. Twenty-five haemophiliacs with HA, 25 haemophiliacs without HA (NHA) and 25 healthy control subjects (CTL) took part in this study. Tests were performed on a force platform and the subjects remained as still as possible for 30 s under different conditions: (i) bilateral stance with eyes open;

Postural control is essential when carrying out everyday activities and its possible disorders have a very significant impact on personal autonomy. To provide the means to accurately measure postural control in the clinical environment, this study checks and discusses the suitability of procedures for a new balance assessment system with a stabilometric platform (MoveHuman-Dyna © UZ-IDERGO), which meets the criteria of clinical stabilometric standardisation established by the International Society for Posture and Gait Research (ISPGR) at the Bologna meeting (2009). The study was applied to a sample of 30 healthy volunteers (12 women, 18 men) aged between 18 and 30 years. A total of six balance tests were performed: four variations of the Romberg test, one test for a study of the limits of stability (LoS) and one test for rhythmic weight shift (RWS). Analysis of the results confirms that the variables assessed yielded similar values to other studies, the consistency of values between...
