Experimental Comparison of Efficacy for Three Handfeeding Techniques in Dementia.

ABSTRACT: Nursing home (NH) residents who require assistance during mealtimes are at risk for malnutrition. Supportive handfeeding is recommended, yet there is limited evidence supporting use of a specific handfeeding technique to increase meal intake.To compare efficacy of three handfeeding techniques for assisting NH residents with dementia with meals: Direct Hand (DH), Over Hand (OH), and Under Hand (UH).A prospective pilot study using a within-subjects experimental Latin square design with randomization to one of three handfeeding technique sequences.30 residents living with advanced dementia in 11 U.S. NHs.Time required for assistance; meal intake (% eaten); and feeding behaviors, measured by the Edinburgh Feeding Evaluation in Dementia (EdFED) scale.Research Assistants provided feeding assistance for 18 video-recorded meals per resident (N = 540 meals). Residents were assisted with one designated technique for 6 consecutive meals, changing technique every 2 days.Mean time spent providing meal assistance did not differ significantly between techniques. Mean meal intake was greater for DH (67 ± 15.2%) and UH (65 ± 15.0%) with both significantly greater than OH (60 ± 15.1%). Feeding behaviors were more frequent with OH (8.3 ± 1.8%), relative to DH (8.0 ± 1.8) and UH (7.7 ± 1.8).All three techniques are time neutral. UH and DH are viable options to increase meal intake among NH residents with advanced dementia and reduce feeding behaviors relative to OH feeding.

Project description:PurposeThe purpose of this study was to evaluate three different methods of attachment of continuous loop suspensory cortical preparation of all soft tissue central quad tendon grafts compared to a bone block control for anterior cruciate ligament reconstruction on construct displacement and load to failure.MethodsThirty-two cadaveric central quadriceps tendon (CQT) specimens were harvested, using three clinical techniques for graft fixation: cortical button alone (BTB EB), BTB cortical button with rip-stop suture (BTB RS), and continuous loop cortical button (BTB CL). A control group was also included that consisted of a bone block secured within testing clamps (BTB CON). Specimens were preloaded to 150 N. Tendons were then cyclically loaded between 50 N and 250 N for 1,000 cycles at .5 Hz. Displacement was measured at the point of fixation of the CQT after the 150 N preload, 250 N initial load and every 100th cycle. The specimens were loaded to failure after 1,000 cycles.ResultsThere was a significant increase in displacement from .32 ± .56 mm for the BTB CON to 1.91 ± 1.13 mm for the BTB RS (P = .014) and 3.85 ± 2.32 mm for the BTB CL condition (P = .023). There was no significant increase in displacement for BTB EB (P = .182). Failure occurred for all of the BTB CL and 62.5% of the BTB EB specimens within the first 50 cycles. Twenty-five percent of the BTB CON specimens and 12.5% BTB RS failed at ∼400 and 500 cycles, respectively. Similar failure loads were observed for the BTB CON and the BTB RS (446.4 ± 151.46 N vs 505.74 ± 131.41 N; P = .99) Failure testing was not feasible for the BTB CL and BTB EB preparation methods.ConclusionIn response to cyclic loading, the three all-soft tissue suspensory conditions experienced significantly greater displacement compared to the bone block controls. None of the soft-tissue conditions appeared superior when compared to each other.Clinical relevanceIt remains unknown which method of soft-tissue suspensory provides optimal fixation. As these autografts become more common, it is essential to evaluate which fixation methods provide superior outcomes.
