Correlation between kinetic and kinematic measures, clinical tests and subjective self-evaluation questionnaires of the affected upper limb in people after stroke.

Introduction: Assessment of stroke recovery should include multiple sources of information in order to obtain a complete understanding of the individual's rehabilitation progress. Self-evaluation questionnaires' scores do not always correspond to the scores of commonly used clinical evaluation tools. The purpose of this study was to assess the relationship between self-evaluation questionnaires, clinical tests, and kinematic and kinetic analyses of the affected upper limb after stroke, and to determine the correlation between these measures and self-reported general function 2-4 years after the stroke.

Corrigendum: Correlation between kinetic and kinematic measures, clinical tests and subjective self-evaluation questionnaires of the affected upper limb in people after stroke.

A survey of Israeli physical therapists regarding reactive balance training.

Background: 'Reactive balance training' (RBT) was developed to improve balance reactions to unexpected losses of balance. Although this training method is effective, its practical usage in the field of physical-therapy in Israel and world-wide is still unclear.

Aims: This study aimed to evaluate the extent of RBT use in physical-therapy clinics in Israel, to identify the significant barriers to/facilitators for implementing RBT in clinical practice among physical therapists, and to determine which aspects of RBT most interest physical therapists in Israel.

Successful Negotiation of Anticipated and Unanticipated Obstacles in Young and Older Adults: Not All Is as Expected.

Background: Tripping over an obstacle is one of the most common causes of falls among older adults; however, the impact of obstacle parameters and subject characteristics are not well described.

Objectives: To evaluate age-associated changes in the ability to negotiate obstacles and the role of obstacle parameters (e.g.

The inter-observer reliability and agreement of lateral balance recovery responses in older and younger adults.

The purpose of this study was to evaluate the inter-observer reliability and agreement of balance recovery responses, step and multiple-steps thresholds, and kinematic parameters of stepping responses. Older and younger adults were exposed to 36 progressively challenging right and left unannounced surface translations during quiet standing. Subjects were instructed to "react naturally".

Perturbation exercises during treadmill walking improve pelvic and trunk motion in older adults-A randomized control trial.

Background: Most falls among older adults occur while walking. Pelvic and trunk motions are required to maintain stability during walking. We aimed to explore whether training that incorporates unexpected loss of balance during walking that evokes balance recovery reactions will improve pelvic, thorax, and trunk kinematics at different walking speeds.

Gait Coordination Deteriorates in Independent Old-Old Adults.

Human gait is symmetric and bilaterally coordinated in young healthy persons. In this study, we aimed to explore the differences in bilateral coordination of gait as measured by the phase coordination index (PCI), gait asymmetry, and stride time variability of gait between four age groups. A total of 44 older adults were recruited: nine young-old (age 70-74 years), 26 old (age 75-84 years), nine old-old (>85 years and older), and 13 young adults (age 20-30 years).

Old adult fallers display reduced flexibility of arm and trunk movements when challenged with different walking speeds.

Specific patterns of pelvic and thorax motions are required to maintain stability during walking. This cross-sectional study explored older-adults' gait kinematics and their kinematic adaptations to different walking speeds, with the purpose of identifying mechanisms that might be related to increased risk for falls. Fifty-eight older adults from self-care residential facilities walked on a treadmill, whose velocity was systematically increased with increments of 0.

Unexpected perturbations training improves balance control and voluntary stepping times in older adults - a double blind randomized control trial.

Background: Falls are common among elderly, most of them occur while slipping or tripping during walking. We aimed to explore whether a training program that incorporates unexpected loss of balance during walking able to improve risk factors for falls.

Methods: In a double-blind randomized controlled trial 53 community dwelling older adults (age 80.

Age-related differences in pelvic and trunk motion and gait adaptability at different walking speeds.

This study aimed at investigating age-related changes in gait kinematics and in kinematic adaptations over a wide range of walking velocities. Thirty-four older adults and 14 younger adults walked on a treadmill; the treadmill velocity was gradually increased in increments of 0.2miles/hour (mph) (1.

Frontal plane instability following rapid voluntary stepping: effects of age and a concurrent cognitive task.

Background: Quick step execution may prevent falls when balance is lost. Lateral steps often emerge as a consequence of frontal plane instability arising after the first rapid step. In this study, we suggest a new analysis, focusing on the variability of the frontal plane fluctuations of center of pressure (CoP), that is, mediolateral instability, and their changes over time during and immediately following rapid voluntary stepping in older and younger adults in single- and dual-task conditions.

Characteristics of balance control in older persons who fall with injury--a prospective study.

Objective: Older adults who have recently fallen demonstrate increased postural sway compared with non-fallers. However, the differences in postural control between older adults who were seriously injured (SI) as a result of a fall, compared with those who fell but were not injured (NSI) and non-fallers (NFs), has not been investigated. The objective of the present study was to investigate the underlying postural control mechanisms related to injuries resulting from a fall.

Do voluntary step reactions in dual task conditions have an added value over single task for fall prediction? A prospective study.

Background And Aims: Stepping reactions play a critical role in responding to balance perturbations, whether they are a consequence of external perturbation or self-induced in nature. The aim of the present study was to determine prospectively the capacity of voluntary stepping performance in singleand dual-task conditions, to predict future falls among older community-dwelling persons. We also aimed to assess whether dual task conditions have an added value over single tasks for fall prediction.

A retrospective analysis of balance control parameters in elderly fallers and non-fallers.

Background: A cross-sectional retrospective study of parameters reflecting balance function in elderly fallers and non-fallers was conducted to better understand postural control mechanisms in individuals prone to falls.

Methods: Ninety-nine old adults (65-91 years, mean age 78.4 (SD 5.

Self reported function and disability in late life: a comparison between recurrent fallers and non-fallers.

Purpose: To compare self-reported function and disability between fallers and non-fallers.

Method: Self-reported late life function and disability (LLFDI) were evaluated among 100 elderly persons who live independently in the community in a cross sectional study. The function component evaluates difficulty in performing physical activities in upper and lower extremity and the disability component evaluates limitations in life activities and frequency in taking part in life tasks.

Regular exercise in the elderly is effective to preserve the speed of voluntary stepping under single-task condition but not under dual-task condition. A case-control study.

Background: Stepping response may be considered the most important postural reaction to prevent a fall because it is the inability to respond effectively to a loss of balance that ultimately determines whether a fall occurs. However, very little has been studied on the effect of exercising on step execution behavior in the elderly.

Objectives: To explore whether older persons who exercise regularly have faster voluntary stepping times than sedentary elderly persons.

Relationship between self-reported function and disability and balance performance measures in the elderly.

This study evaluated the reliability and validity of the Hebrew version of the Late-Life Function and Disability Instrument (LLFDI). Fifty-five older adults (mean age 79.7 +/- 5.
