Prognostic Implications of Predischarge Assessment of Gait Speed After Hip Fracture Surgery.

BACKGROUND AND PURPOSES: Hip fracture represents one of the most severe injuries in the older adults. In long-term survivors, disability is common and walking ability may be considered an important predictor of functional recovery. We investigated whether 4-m gait speed, assessed in older persons early after surgical repair of hip fracture, could predict functional recovery and subsequent development of major clinical outcomes. METHODS: This was a prospective cohort study. We included adults older than 65 years, admitted to a community acute care hospital with hip fracture, undergoing surgical repair. As soon as the participant was able to stand and walk, using walking aids as needed but with no person's help, the 4-m walking speed was tested as the main predictive variable. The outcome variables included the change in the Barthel Index (BI) from prehospital through 1 year postoperative as a continuous variable and 2 dichotomous outcomes, that is, (1) a decrease in BI greater than 5 points in 1 year and (2) a composite endpoint, combining 5+ points BI decline, death, falls, institutionalization, and need for 24-hour home assistance in 1 year. RESULTS: Sixty-two participants (mean age = 85 years) were enrolled and evaluated, on average 6 days (standard error of the mean [SEM] = 0.2) after hip fracture surgery. Compared with prefracture (mean = 96.3; SEM = 0.9), BI decreased 1 month after surgery (mean = 76.5; SEM = 2.1) and recovered only partially at 2 (mean = 84.1; SEM = 2.2) and 12 months (mean = 87.2; SEM = 2.8). A predischarge value of the walking speed below the median (20.5 cm/s) predicted a substantial BI reduction throughout the 12 months. Furthermore, the adjusted risk of a decline in functional status was reduced by 5% (odds ratio = 0.95; 95% confidence interval, 0.91-0.997; P = .038) and that of the combined outcome by 7% (odds ratio = 0.93; 95% confidence interval, 0.88-0.99; P = .013) for each centimeter per second of predischarge walking speed. DISCUSSION AND CONCLUSION: The 4-m walking speed, measured early after surgical repair of hip fracture, has profound long-term prognostic implications. This assessment approach might prove helpful in clinical decision-making on the postoperative management of older hip fracture persons.

Scale for contraversive pushing: cutoff scores for diagnosing "pusher behavior" and construct validity.

BACKGROUND AND PURPOSE: Considerable disagreement exists among researchers with regard to the prevalence, pathophysiology, and treatment of "pusher behavior" (PB), partly because of different testing procedures. This study was primarily aimed at establishing cutoff scores for and the construct validity of the Scale for Contraversive Pushing (SCP). The prevalence of PB in people with right- and left-brain lesions also was investigated. SUBJECTS AND METHODS: The study subjects were 105 consecutive patients with recent stroke. Two methods were used to diagnose PB: clinical examination and SCP score with 3 different cutoff points--an SCP total score of greater than 0 (Crit_1), subscores in each section of the scale of greater than 0 (Crit_2), and subscores in each section of the scale of > or =1 (Crit_3). Clinical and SCP diagnoses were independently made by different examiners. The Cohen kappa coefficient was used to determine the agreement between clinical and SCP diagnoses. The construct validity of the SCP was estimated by calculation of Spearman rank correlation coefficients for SCP and balance, mobility, and functional scores. RESULTS: The agreement between clinical and SCP diagnoses was low (kappa=.212) when Crit_1 was used. Crit_2 led to the highest agreement with the clinical diagnosis (kappa=.933). However, only Crit_3, although globally less accurate (kappa=.754), ensured no false-positive results. The construct validity of the SCP was demonstrated by significant (P<.001) moderate to high correlations with mobility (rho=.595), functional (rho=.632), and balance (rho=.666) scores. The prevalence of PB was not influenced by the side of the lesion. A limitation of the study was that the reliability of the clinical examination method was not investigated. DISCUSSION AND CONCLUSION: The results support the validity of the SCP and suggest the need to choose different SCP cutoff criteria (Crit_2 or Crit_3) according to the aim of the evaluation.

Physiological asymmetry of trunk ranging and pelvis motility: an anatomo-functional study in 80 healthy subjects.

A key feature in physiotherapeutic treatment of patients with motion disturbances is the appropriate ranging of the trunk and pelvis motility. Eighty subjects randomly selected and free from known pathology of the muscular-skeletal and/or of the neurological system classed into four groups according to the age and the sex have been assessed, by using a new, simple and easy administrable tool. Our results demonstrate that the new measurement tool showed a very low intra- and inter-observer variability, that healthy subjects showed a more adduced and elevated right scapula if compared to the contralateral one and, as regard as the pelvic motion, a broader joint excursion in passive motion compared with active motion in the overall group, a broader joint excursion in young subjects compared with elderly ones, and a broader joint excursion in female subjects compared with males subjects. In conclusion our study allowed to identify a range of physiological asymmetry and pelvis motility. Such a range of physiological asymmetry might be useful as a reference for the physiotherapists.
