Ageing commonly disrupts the balance control and compensatory postural responses that contribute to maintaining balance and preventing falls during perturbation of posture. This can lead to increased risk of falling in old adults (65 years old and over). Therefore, improving compensatory postural responses during walking is one of the goals in fall prevention programs. Training is often used to achieve this goal. Most fall prevention programs are usually directed towards improving voluntary postural control and thus are able to improve compensatory postural responses. Since compensatory postural responses triggered by a slip or a trip are not under direct voluntary control they cannot be trained through voluntary exercises. This paper describes the Balance Measure & Perturbation System (BaMPer System) a system that provides small, controlled and unpredictable perturbations during treadmill walking providing valuable perturbation, which allows to train their compensatory postural responses during walking which thus hypothesize to improve “recovery reflexes ” in older adults. Key words: Ageing, anticipatory postural adjustments, compensatory postural responses
