Randomised controlled trial of home-based walking programmes at and below current recommended levels of exercise in sedentary adults

Objectives: To determine, using unsupervised walking programmes, the effects of exercise at a level lower than currently recommended to improve cardiovascular risk factors and functional capacity.

Let your feet do the walking: constraints on the stability of bipedal coordination

In this paper we consider whether the behaviour of the neural circuitry that controls lower limb movements in humans is shaped primarily by the spatiotemporal characteristics of bipedal gait patterns, or by selective pressures that are sensitive to considerations of balance and energetics. During the course of normal locomotion, the full dynamics of the neural circuitry are masked by the inertial properties of the limbs. In the present study, participants executed bipedal movements in conditions in which their feet were either unloaded or subject to additional inertial loads. Two patterns of rhythmic coordination were examined. In the in-phase mode, participants were required to flex their ankles and extend their ankles in synchrony. In the out-of-phase mode, the participants flexed one ankle while extending the other and vice versa. The frequency of movement was increased systematically throughout each experimental trial. All participants were able to maintain both the in-phase and the out-of-phase mode of coordination, to the point at which they could no longer increase their frequency of movement. Transitions between the two modes were not observed, and the stability of the out-of-phase and in-phase modes of coordination was equivalent at all movement frequencies. These findings indicate that, in humans, the behaviour of the neural circuitry underlying coordinated movements of the lower limbs is not constrained strongly by the spatiotemporal symmetries of bipedal gait patterns.

'Like walking on eggshells': Service user views and expectations of the child protection system

This paper reports on a study of service users' views on Irish child protection services. Qualitative interviews were conducted with 67 service users, including young people between 13 and 23. The findings showed that despite refocusing and public service management reforms, service users still experience involvement with the services as intimidating and stressful and while they acknowledged opportunities to participate in the child protection process, they found the experience to be very difficult. Their definition of ‘needs’ was somewhat at odds with that suggested in official documentation, and they viewed the execution of a child protection plan more as a coercive requirement to comply with ‘tasks’ set by workers than a conjoint effort to enhance their children's welfare. As in previous studies, the data showed how the development of good relationships between workers and service users could compensate for the harsher aspects of involvement with child protection. In addition, this study demonstrated a high level of discernment on the part of service users, highlighting their expectation of quality standards in respect of courtesy, respect, accountability, transparency and practitioner expertise.
