Resumo

Introdução: As quedas nos idosos constituem um problema de saúde pública devido ao seu impacto funcional. A avaliação conjunta do equilíbrio e da marcha permite uma melhor estratificação deste risco.

Objectivo: Identificar perfis funcionais de equilíbrio e marcha em idosos através da avaliação conjunta da Escala de Tinetti e do Teste de Marcha Cronometrada (Timed Up and Go).

Metodologia: Foi realizado um estudo transversal, observacional, quantitativo e não experimental. Participaram 81 idosos (≥60 anos), avaliados através de registos clínicos, da Escala de Tinetti e do Teste de Marcha Cronometrada (Timed Up and Go). A análise incluiu estatística descritiva, coeficiente Kappa de Cohen (k), correlação de Spearman e testes de associação clínica.

Resultados: A pontuação média na escala de Tinetti foi de 25,32 ± 3,93 pontos (77,8% baixo risco, 16,0% risco moderado, 6,2% alto risco), e a pontuação média no teste Timed Up and Go foi de 9,96 ± 2,09 segundos (63,0% risco normal, 37,0% risco moderado). A concordância global foi de 58,0%, com predominância do perfil Baixo-Normal (51,9%). A concordância diagnóstica foi fraca (k = 0,22; p < 0,001), detetando 25,9% com baixo risco na escala de Tinetti, mas risco moderado na escala Timed Up and Go. Verificou-se uma correlação inversa significativa entre os testes, sem associação estatisticamente significativa com doenças crónicas (p > 0,05).

Discussão: Os achados corroboram a utilidade de uma avaliação combinada, dado que a divergência diagnóstica confirma que ambos os testes avaliam dimensões funcionais complementares e não intercambiáveis ​​do desempenho. Conclusões: A avaliação conjunta otimiza o rastreio clínico geriátrico. A escala Timed Up and Go capta com sucesso as limitações incipientes na mobilidade dinâmica antes que a deterioração altere a categoria de risco na avaliação observacional da escala de Tinetti, independentemente das comorbilidades do doente.
