For a variety of reasons, tolerating wearing a mask is challenging for many individuals with intellectual and developmental disabilities (IDDs). Therefore, we evaluated behavioral strategies to promote compliance with wearing a mask with six hospitalized individuals diagnosed with IDDs. One participant was compliant with wearing the mask for extended durations during baseline while engaging in various activities (e.g., academics, leisure). For the other five individuals, engagement in activities alone was ineffective. Blocking mask removal, reinforcement for mask wearing, and noncontingent access to preferred activities or competing stimuli were then evaluated using a changing-criterion design in which the duration participants were required to tolerate the mask gradually increased. Increases in compliance with mask wearing were achieved with all participants; however, the terminal duration was attained for only four of the five individuals.

To investigate the efficiency of internal fixation with bone grafting after bone transport for treatment in large-segment bone defects of the lower-limbs. This prospective study recruited 100 patients with lower limb tibial segmental bone defects, and based on a random number table they were divided into a control group (n=50, simple bone transport surgery) or an observation group (n=50, internal fixation with bone grafting at docking site after bone transport). The fracture healing time, bone healing index, external fixation time in both groups were compared. The knee function, joint range of motion, and the function
