| dc.description.abstract | ABSTRACT
Introduction: the dynamics of the head, arms and back is vital for maintaining,
balance during gait with advancing age. Hyperkyphosis, common in the elderly
requires compensations for maintaining balance and, consequently, alter the quality
of posture and gait, increasing the risk of falls.
Objectives: primary objective: to determine the participation of the pelvic and the
vertebral column angles in gait and balance parameters in women over 60 years of
age. Secondary objective: to evaluate the relationships of the pelvic and the vertebral
column angles with clinical tests for gait and balance.
Methods: this is a transversal study of elderly women without gait dysfunction and
preserved cognition (MiniMental - MMSE> 24. Berg Scale (BS), timed up and go
(TUG), comfortable and fast walk in 10 m, and fall questionnaire were used. The
sagittal radiological evaluation was performed for Thoracic Cobb (TC) and Lumbar
(LC), Pelvic Incidence (PI), Sacral Inclination (SI) and Pelvic Inclination (PeI). The
gait evaluation was assessed by accelerometry in a 30-meter walk and the
parameters evaluated were: step length, Root Mean Square (RMS ) of acceleration
during walking, symmetry, step and regularity of the stride in the anteroposterior (AP)
and vertical (V) planes. Results: fifty-five elderly women with a mean age of 72 years
(SD=6) were recruited. FES-I-Brazil was 25.2 (6.6); BS 49.4 (3.8); TUG 9.9 (2.2)
seconds; Comfortable walking 1.09 (0.19) m/s, fast walking 1.38 (0.24) m/s. The
radiographic angles were: TC 52 (15°), LC 55 (17°), PI 57 (11°), SI 39 (11°) and PeI
17 (8°). Correlations of BS with IS (0,377) and PeI with 10m of fast walk (0.366); LC
with SI angles (0.637) and PeI with SI (0.674) were observed. Regarding
accelerometry, SI was associated with step length (p = 0.082) and symmetry (p
<0.001) and step regularity (p <0.001) in the AP plane. Association was found
between LC and RMS in the V plane (p = 0.076), stride regularity in AP (p = 0.016)
and regularity of the V-step (p = 0.02). In addition, TC was associated with stride
regularity (p = 0.026), step regularity (0.026); symmetry in the AP plane (0.034) and
stride regularity in V plane (p = 0.01). Conclusion: In elderly women with
preservation of functional capacity the angles of the spine and pelvis interfere with
gait quality, particularly in the anteroposterior plane. | |
| dc.description.abstract | Introdução: a dinâmica de cabeça, braços e tronco é considerada de vital
importância para se manter o equilíbrio durante a marcha. A hipercifose, comum em
idosos, obriga a compensações para a manutenção do equilíbrio, o que pode alterar
a qualidade da postura e da marcha, aumentando o risco de quedas. Objetivos:
primário, determinar a participação dos ângulos da pelve, da lordose lombar e da
cifose torácica nos parâmetros de marcha e equilíbrio em mulheres acima de 60
anos, secundário, avaliar as relações de ângulos da pelve e coluna lombar com
testes clínicos de marcha e equilíbrio. Métodos: estudo transversal, com idosas sem
disfunção para marcha, MiniMental >24. Avaliação: questionário de quedas FES-IBrasil,
Escala de Berg (EB), TUG, marcha confortável e mais rápida em 10 m, em 30
m com acelerômetro o MiniMod DynaPort ®. Avaliação radiológica no plano sagital
para os Ângulos: Cobb torácico (CT) e Lombar (CL), Incidência Pélvica (IP),
Inclinação Sacral (IS) e Inclinação Pélvica (IPe). Dados da acelerometria:
comprimento do passo, “Root Mean Square” (RMS), simetria, regularidade do passo
e da passada nos planos anteroposterior (AP) e vertical (V).
Resultados: 55 idosas com idade [idade (DP] de 72(6) anos; FES-I-Brasil 25,2(6,6);
Berg 49,4(3,8); TUG 9,9(2,2) segundos; marcha confortável 1,09(0,19) m/s, marcha
rápida 1,38(0,24) m/s. Ângulos: CT 52°(15), CL 55° (17), IP 57° (11), IS 39° (11) e
IPe 17° (8). Encontramos correlações entre EB com IS (0,377), e IPe com 10m
rápido (0,366); entre CL com ângulo de IS (0,637) e de IPe com IS (0,674).
Encontrou-se associação significante: IS com o comprimento do passo (p=0,082) e a
simetria (p<0,001) e regularidade do passo (p<0,001) no plano anteroposterior (AP);
CL com o RMS em V (p=0,076), regularidade da passada em AP(p=0,016) e
regularidade do passo em V (p=0,02); CT com a regularidade da passada
(p=0,006), do passo (p=0,026 ) , simetria no plano AP (0,034), regularidade da
passada em V (p=0,01). Conclusão: os ângulos da coluna e da pelve interferem na
qualidade de marcha em mulheres idosas com preservação da capacidade
funcional. | |
