Executive dysfunction can affect community integration in adults with traumatic brain injury (TBI). The Cognitive Orientation to daily Occupational Performance (CO-OP) approach has shown some promise in promoting functional improvements in adults with executive dysfunctions post TBI. However, access to rehabilitation is often limited especially in rural communities. This study aimed to (1) investigate the feasibility of administering the CO-OP approach in a tele-rehabilitation format and (2) examine its impact on community integration and executive dysfunction. A pilot series of 3 case studies was conducted. Participants identified 5 goals; 3 were trained and 2 were untrained to allow examination of transfer. Outcome measures included the Canadian Occupational Performance Measure, the Mayo-Portland Adaptability Inventory-4 Participation Index, and the Dysexecutive Questionnaire. Descriptive analyses demonstrated goal achievement and transfer, suggesting it is feasible to implement the CO-OP approach in a tele-rehabilitation format. Community integration and executive dysfunction behaviours also showed trends towards improvement.

Introduction: Disabling hearing loss is one of the most common sensory deficits; affecting approximately 466 million people worldwide. In the South African context, public health facilities have an uneven ratio between audiologists and patients in need and thus audiological services are often minimal. Successful application of tele-health may increase the scope of audiological services for hearing aid (HA) users. Research is needed to investigate feasibility of tele-health for audiological rehabilitation programmes such as auditory training (AT). Aim and Objectives: This study aimed to investigate the feasibility of implementing a telerehabilitation programme in a South African public health context. Objectives included: 1) determining online AT compliance; 2) determining the effect of online AT on speech perception in noise; 3) assessing experience and benefit of tele-rehabilitation through questionnaires and interviewing; and 4) cost estimation around tele-rehabilitation implementation. Research Design: A convergent mixed methods design with a feasibility approach was utilized. Data collection was through questionnaires, in-booth speech assessments, online AT and face-to-face interviewing. Participants undertook online AT over four weeks. Pre-/post- online AT: the APHAB, QuickSIN, Entrance/Exit Questionnaires, Interviews and System Usability Scale were administered. Descriptive statistics were used to analyse the quantitative data collected, and descriptive thematic analysis was used for the qualitative data. Study sample: Purposive sampling was used and three female adult (35 - 55 years) HA users from a public health facility participated. Results: 1) High compliance rate (84.82%) with 3 hours 25 minutes total clinician contact time, 2) clinical benefit with improvement in listening skills and perceived HA benefit, 3) positive participant feedback, and 4) estimated cost at R1350.00 per person. Conclusions: Findings from this feasibility study can be seen as positive indicators towards the use of tele-health as a delivery modality for audiological rehabilitation, also a tele-health hybrid model is recommended. However, larger-scaled research is needed.

Many performance-based assessment tools are available to measure upper extremity function. Most define hand function by the time taken to complete a task. A new computer game-based hand-arm function evaluation (GHA) tool has been developed to quantify fine and gross object manipulations skills. Objective of this study was to evaluate the test-retest reliability and convergent validity of the GHA assessment tool. Thirty stroke clients with the mean age of 68.41 years were recruited. Test-retest reliability was assessed by Intraclass correlation coefficient (ICCs) and t-test. Convergent validity between GHA and the Wolf Motor Function Test (WMFT) was determined using the Pearson’s correlation coefficient. Most of the GHA outcome measures had moderate to high ICC (0.5-0.9). With scant exceptions, low correlations were observed between GHA measures and WMFT score. The ICC values reflected the complexity of the tasks, more complex task showed lower ICCs values. / October 2016

The work presented in this dissertation was focused on developing an affordable, automated, upper extremity exercise system suitable for individuals with stroke and spinal cord injury (SCI). The three studies presented in this thesis demonstrated the efficacy of functional electrical stimulation-assisted exercise therapy (FES-ET). Furthermore a protocol was developed to implement FES-ET in participants homes via tele-rehabilitation. The protocol included the use of an improved version of the bionic glove, an FES device that enhanced hand grasp and release in SCI individuals in combination with a custom-built workstation that enabled task-oriented rehabilitation in the home setting, supervised over the Internet. In the course of these studies, an objective hand function assessment tool was developed to complement tele-supervised FES-ET and provide the therapist with an unbiased evaluation of the participants impairment. A major section of this dissertation is concerned with the development and testing of a novel exercise workstation named the ReJoyce (Rehabilitation Joystick for Computer Exercise), that can assess hand function electronically. The ReJoyce is an instrumented workstation that provides standardized upper extremity rehabilitation based on ADLs, in the guise of computer games played by manipulating attachments on the device. The three studies presented in this thesis focus on the scientific merits and the logistics of providing tele-supervised FES-ET with this workstation. The first study demonstrated the feasibility of treating and assessing individuals on the workstation who had recently suffered a stroke. The second study explored the relationship between the quantitative assessment of hand function with the workstation and two widely-used clinical tests. The last study involved daily, tele-supervised FES-ET or conventional exercises and therapeutic electrical stimulation (TES), maintained for 6 weeks, with SCI participants spread out over a large geographical area. FES-ET performed with the workstation resulted in statistically significant and clinically important improvements in hand function that were greater than those produced by the more conventional protocol. The results demonstrated the importance of including a range of exercises aimed at improving both strength and dexterity. It is concluded that tele-supervised FES-ET on a standardized workstation is feasible, effective and affordable in the current healthcare settin
