Equilibri de tronc predictor de la funció motora en l'emiplègic vascular

Duarte Oller, Esther 16 June 2006 (has links)
TRUNK BALANCE AS A PREDICTOR OF MOTOR OUTCOME IN PATIENTS WITH STROKE ABSTRACTBackground: The search for predictors of functional stroke outcome has always been matter of research in Physical Medicine and Rehabilitation. Outcome prediction at an early stage enables clinicians not only to inform patients and their families, but also to set realistic therapeutic goals. A lot of prognostic studies have evaluated several factors, which either individually or in combination claim to predict functional outcome in stroke. The Trunk Control Test (TCT) proposed by Collin & Wade administered at 6 weeks post-stroke is a predictor of the walking ability at 18 weeks. The TCT reliability and validity has been demonstrated in stroke patients, as well as its positive correlation with disability at hospital discharge from in-patient rehabilitation measured with the Functional Independence Measure (FIM). In a previous study, a predictive model which only includes the FIM and the TCT measured at admission of patients to a rehabilitation ward, predicts 66.5% of the variability of the functional level at discharge (total FIM). Objective: To develop an early model to predict motor function (disability, walking ability and balance)at 6 months, taking into account the TCT and other valid predictors evaluated in the first and second week after suffering a stroke.Patients and Methods: Seventy-five consecutive patients with first stroke who were admitted to a rehabilitation hospital were studied. Sex, age, the stroke type, urinary incontinence, the National Institutes of Health Stroke Scales (NIHSS) and the TCT scores (assessed at first and second week post-stroke) as independent variables. Motor function outcome at 6 months after stroke is defined by the use the Rankin score, the motor FIM and the Berg Balance Scale (BBS).Results: Older patients, women and those with initial urinary incontinence and lower TCT and NIHSS scores showed significantly worse motor outcomes at first and six months after the stroke (Rankin, motor FIM and BBS). A multiple regression reveals that only age and the TCT (at 14 days after stroke) accounts for the 61.1% of the variance in the motor FIM score at 6 months after stroke. When the TCT is registered at 7 days after stroke, age and the TCT accounts for the 51.7% of the motor FIM variance. A cluster analysis identifies 12 patients with low outcome scores: Rankin 4-5, motor FIM < 59 and BBS < 5. The ROC curves show a better prediction ability for the TCT than the NIHSS at 14 days after stroke. Logistic regression is used to predict the probability of achieving in this group with low motor scores. The TCT &#61603; 50 at 14 days after stroke is a significant predictive factor of poor motor outcome at 6 months after stroke (Sensibility 83.3%, Specificity 85.7%) (OR=30.0, 95% CI 4.7 - 247.3). The TCT &#61603; 24 at 7 days after stroke is a significant, but obviously worse predictive factor of poor motor outcome (Sensibility 66.7%, Specificity 89.3%) (OR=16.7, 95% CI 3.2 - 97.5). Discussion and conclusions: Age, sex, urinary incontinence, TCT and NIHSS scores are related with disability, balance and walking ability six months after the stroke. It is possible to approach to the motor functional outcome at 6 months after stroke by the early use of data easily recorded as age and the TCT. In this study the TCT even overcomes the NIHSS, a comprehensive neurological measure whose ability to predicts outcome has been well documented in stroke patients. The reproducibility of this model must be cross-validated in future studies. The TCT registered at 14 days provides better prediction values compared with those obtained at 7 days after stroke. This study shows that the TCT early administered predicts motor outcome at six months after stroke.EQUILIBRI DE TRONC: PREDICTOR DE LA FUNCIÓ MOTORA EN L'HEMIPLÈGIC VASCULAR RESUMIntroducció: La cerca de factors predictors del resultat funcional després de patir un ictus és objecte constant d'investigació en Medicina Física i Rehabilitació. Un pronòstic funcional en fases inicials permet al clínic informar als pacients i a la seva familia, però també establir objectius terapèutics realistes. Molts estudis han avaluat la capacitat predictora de diferents factors individual i combinadament. El Test de Control de Tronc (TCT) registrat a les 6 setmanes de l'ictus és un predictor de la capacitat de marxa a les 18 setmanes. La fiabilitat i validesa del TCT s'ha demostrat en pacients amb ictus, així com la seva correlació positiva amb la discapacitat a l'alta hospitalaria. Un model predictiu que inclou només el TCT i el Functional Independence Measure (FIM) registrats a l'ingrés en la unitat de rehabilitació d'hospitalització aguda prediu el 66.5% de la variabilitat del FIM a l'alta.Objectius: Conèixer la relació de les variables predictores amb els resultats de funció motora global al mes i als sis mesos de l'ictus. Construir un model de predicció precoç de la funció motora (discapacitat, capacitat de marxa i equilibri) als 6 mesos, tenint en compte el TCT i altres predictors vàlids avaluats en la primera i en la segona setmana després de patir l'ictus.Pacients i Mètode: estudi longitudinal i prospectiu en 75 pacients consecutius ingressats per un primer episodi d'ictus. Les variables independents van ser: edat, sexe, tipus d'ictus, incontinencia urinària, l'escala d'ictus National Institutes of Health Stroke Scales (NIHSS) i el TCT (recollits en la primera i segona setmanes de l'ictus). Els resultats de funció motora al mes i als 6 mesos de l'ictus es van definir amb l'escala de Rankin, la subescala motora del FIM i l'escala d'equilibri Berg Balance Scale (BBS).Resultats: els pacients de més edat, les dones i els que tenen incontinència urinària inicial i puntuacions més baixes de TCT i NIHSS són els que presenten significativament pitjors resultats de funció motora tant en el primer com en el sisè mes de l'ictus (Rankin, FIM motor i BBS). Una anàlisi de regressió múltipla determina que només amb l'edat i el TCT de la segona setmana s'explica el 61.1% de la variabilitat del FIM motor als 6 mesos de l'ictus. Quan el TCT es registra en el setè dia de l'ictus, l'edat i el TCT expliquen el 51.7% de la variabilitat del FIM motor. Una anàlisi de conglomerats identifica 12 pacients amb resultats baixos de funció motora: Rankin 4-5, FIM motor < 59 i BBS < 5. Les corbes ROC mostren que la millor capacitat predictora correspon al TCT de la segona setmana, per sobre del NIHSS. La probabilitat de tenir un mal resultat motor, es a dir, d'estar entre aquests 12 pacients es calcula mitjançant una anàlisi de regressió logística. Un TCT &#61603; 50 en la segona setmana de l'ictus és un factor predictiu de mal resultat motor als 6 mesos (Sensibilitat 83.3%, Especificitat 85.7%) (OR=30.0, IC 95% 4.7 - 247.3). Un TCT &#61603; 24 en la primera setmana també és un factor predictor significatiu, tot i que menys potent, de obtenir un mal resultat motor als 6 mesos (Sensibilitat 66.7%, Especificitat 89.3%) (OR=16.7, IC 95% 3.2 - 97.5).Conclusions: L'edat, el sexe, la incontinència urinària, el TCT i el NIHSS inicials són factors relacionats amb la discapacitat, equilibri i capacitat de marxa 6 mesos després de l'ictus. És possible aproximar-nos al resultat funcional motor als 6 mesos després de patir l'ictus amb la utilització precoç de dades de fácil recollida com l'edat i el TCT. El TCT recollit en fases inicials prediu el resultat motor als 6 mesos de l'ictus.

Vliv dynamické neuromuskulární stabilizace na motorický deficit u pacientů po cévní mozkové příhodě / The effect of dynamic neuromusculur stabilization on motor deficit in patients after stroke

Zelenková, Jana January 2014 (has links)
The aim of the study was to evaluate the effect of specific rehabilitation concept on the motor deficit in patients after stroke. This concept is used at the Department of inpatient rehabilitation FN Motol, the main component is exercise on the principles of dynamic neuromuscular stabilization (DNS) and is based on the principles of developmental kinesiology. The study included 12 patients after stroke. Probands participated in the 3 week therapy, exercise was carried out twice a day. Significant (p <0.05) improvement in motor function of the arm, hand, leg and foot was demonstrated by using Student`s paired t-test. There was a statistically significant improvement in postural control and reducing shoulder pain (all assessed using a specific scale: Chedoke McMaster Stroke Assessment). Changes in the degree of spasticity were evaluated by Modified Ashworth scale. A statistically significant improvement in the degree of spasticity was observed in these muscle groups: the elbow flexors , adductors of lower limb, knee extensors and hamstrings. It has been shown that the concept of dynamic neuromuscular stabilization can be advantageously used in selected patients after stroke. It is appropriate to supplement the DNS therapy with training of ADL.
