BIONic WalkAide for correcting foot drop.

The goal of this study was to test the feasibility and efficacy of using microstimulators (BIONs) to correct foot drop, the first human application of BIONs in functional electrical stimulation (FES). A prototype BIONic foot drop stimulator was developed by modifying a WalkAide2 stimulator to control BION stimulation of the ankle dorsiflexor muscles. BION stimulation was compared with surface stimulation of the common peroneal nerve provided by a normal WalkAide2 foot drop stimulator. Compared to surface stimulation, we found that BION stimulation of the deep peroneal nerve produces a more balanced ankle flexion movement without everting the foot. A three-dimensional motion analysis was performed to measure the ankle and foot kinematics with and without stimulation. Without stimulation, the toe on the affected leg drags across the ground. The BIONic WalkAide elevates the foot such that the toe clears the ground by 3 cm, which is equivalent to the toe clearance in the unaffected leg. The physiological cost index (PCI) was used to measure effort during walking. The PCI is high without stimulation (2.29 +/- 0.37; mean +/- S.D.) and greatly reduced with surface (1.29 +/- 0.10) and BION stimulation (1.46 +/- 0.24). Also, walking speed is increased from 9.4 +/- 0.4 m/min without stimulation to 19.6 +/- 2.0 m/min with surface and 17.8 +/- 0.7 m/min with BION stimulation. We conclude that functional electrical stimulation with BIONs is a practical alternative to surface stimulation and provides more selective control of muscle activation.

The care of my child with cancer: a new instrument to measure caregiving demand in parents of children with cancer.

The growing societal trend toward delivering more and more illness-related care in the home, driven both by family preferences and by mandates from third-party reimbursers, places additional responsibilities for increasingly complex caregiving on parents of children with serious illness. This article reports on the development and initial field test of The Care of My Child with Cancer, a caregiving demand instrument specific to the childhood cancer population. The instrument demonstrated strong internal consistency and test-retest reliability, and exploratory factor analysis provided initial evidence for the instrument's construct validity. The instrument will now be applied in a collaborative program of nursing research to further investigate caregiving demand and ultimately to develop nursing interventions to maximize medical and quality of life outcomes for children with cancer and their families.

The care of my child with cancer: parents' perceptions of caregiving demands.

Parents are actively involved in the direct care of their ill child receiving cancer treatment by providing and monitoring therapy and by managing symptoms related to the therapy or to the disease itself. Little is known about parents' perception of what helps or hinders them with their caregiving responsibilities or what effect the caregiving role has on the parent. In this descriptive, exploratory study, 151 parents responded to one or more of six open-ended questions that were part of the newly developed instrument, Care of My Child with Cancer. The 1,280 responses were analyzed using a semantic content analysis technique. The most frequently reported effect on parental caregiving involved negative physical and emotional health. One parent responded, "You feel like you lose all control over your life. It's no longer your own." The most desired forms of assistance with the caregiving role were periodic relief from direct caregiving, ongoing assistance with household responsibilities, and different forms of conveniences that could save time and energy. Two types of actual assistance found to be most helpful by parental caregivers included timely education about their child's health status from health care providers and emotional support from family members, friends, and others. These study findings provide the basis for future interventions that may diminish the effect that caregiving demands place on parents of children with cancer.
