Background/objective: Patients with schizophrenia not only have psychiatric symptoms, but also have movement problems, which might also be associated with their reduced quality of life. Little is known about how to improve their movement performance for patients. Manipulating object size and distance is common in occupational therapy practice to evaluate and optimize reaching performance in patients with physical disabilities, but effects of the manipulation in patients with schizophrenia remain unclear. The purpose of this study was to examine whether object size and distance could change performance of reaching kinematics in patients with mild schizophrenia.

Methods: Twenty-nine patients with mild schizophrenia and 15 age- and gender-matched healthy controls were required to reach for, as quickly as possible, a small or large object that was placed at a near or far distance. We measured movement time, peak velocity, path length ratio, percentage of time to peak velocity, and movement units to infer movement speed, forcefulness, spatial efficiency (directness), control strategies, and smoothness.

Results: Patients' reaching movements were slower (p = .017) and less direct (p = .007) than those of controls. A larger object induced faster (p = .016), more preprogrammed (p = .018), and more forceful (p = .010) movements in patients. A farther object induced slower, more feedback dependent, but more forceful and more direct movements (all p < .001).

Conclusion: The results of kinematic deficiencies suggest the need of movement training for patients with mild schizophrenia. Occupational therapists may grade or adapt reaching activities by changing object size and distance to enhance movement performance in patients with schizophrenia.

Introduction: This study analysed the differences in play performance between preschool children with cerebral palsy and those with typical development and investigated the factors influencing functional mobility and manual dexterity on play in children with cerebral palsy.

Method: Sixty preschool children (30 with cerebral palsy; 30 with typical development), were assessed by the revised Knox Preschool Play Scale, being that children with cerebral palsy were also classified according to their functional mobility and manual dexterity.

Results: On average, all measures were significantly smaller in the cerebral palsy group than the typical development group (p≤ .002). Manual function and functional mobility were negatively correlated with material (r = -.456, p = .011; r = -.487, p = .006) and space (r = -.494, p = .006; r = -.784, p = .000). Also the results pointed out a significant correlation with topography and manual function (r = .404, p = .027) and functional mobility (r = .718, p = .000). Pretend play and participation showed no correlation with topography (r = -.051, p = .788; r = -.312, p = .093), manual function (r = -.019, p = .921; r = -.322, p = .083) and functional mobility (r = -.085, p = .657; r = -.308, p = .097).

Conclusion: Play performance of children with typical development was superior to those with cerebral palsy. The degree of impairment of functional mobility and manual function negatively was negatively associated with play exploration but did not relate to pretend play or social interaction in play.

Background: Cultivating empathy towards persons with disabilities has been highlighted as an essential graduate attribute in the occupational therapy profession.

Purpose: With the aim to developing a more holistic understanding of disability, this project seeks to translate an experiential learning activity developed in Canada to the local Singaporean context. Small groups of two to three students were paired with a person with physical disability, known as a community teacher, for a series of visits to observe and participate in their self-care, productivity and leisure activities.

Method: A sequential explanatory mixed methods design was adopted with the administration of an adapted version of the Multidimensional Attitudes Scale Towards Persons with Disabilities on 51 first year occupational therapy students. Seventeen students participated in three focus group discussions at the end of the learning activity.Findings: Comparison of pre- and post-scores using Wilcoxon signed-rank tests of all three subscales of the Multidimensional Attitudes Scale Towards Persons with Disabilities yielded significant improvements. The average score for Affect improved from 42.94 to 32.08, z = -5.43, P <  .001; for Cognition improved from 26.12 to 21.41, z = -4.20, P <  .001; for Behaviour improved from 23.78 to 20.65, z= -4.44, P <  .001. Effect sizes ranged from medium to large. Thematic analysis of focus groups led to the identification of four themes that explained these improvements.Implications: Experiential learning can be effective in cultivating empathy and improving attitudes of occupational therapy students towards persons with disabilities. There is potential to expand this pedagogical approach to other health sciences disciplines.

Background/objective: Fixed flexion deformity of the proximal interphalangeal joint can commonly occur following a traumatic injury impacting on hand function and occupational performance. Numerous interventions have been proposed for fixed flexion deformity resolution. This paper investigates the efficacy of static or dynamic orthoses in reducing fixed flexion deformity contracture following traumatic proximal interphalangeal joint injury.

Methods: A multi-database search of three databases (CINAHL, EMBASE, MEDLINE) was conducted. Data extracted for each study were design, patient descriptions, degree of fixed flexion deformity pre- and post-orthoses, and prescribed interventions and exercise programmes.

Results: The search yielded 643 studies, of which eight met the inclusion criteria. Studies used heterogeneous methodologies investigating various orthotic interventions. Meta-analysis or pooling of results was not possible. Dissimilar orthotic wear regimes were noted in all studies and an alternative clinical significance outcome was found.

Conclusion: More research is required to support clinical reasoning in orthotic choice for fixed flexion deformity of the proximal interphalangeal joint post-traumatic injury.
