This study examined the kinematic differences between a body-powered prosthesis and a biomechatronics prosthesis as a transradial amputee performed activities that involve flexion/extension and supination/pronation of the wrist.
One of the main indicators of the suspension system efficiency in lower limb prostheses is vertical displacement or pistoning within the socket. Decreasing pistoning and introducing an effective system for evaluating pistoning could contribute to the amputees' rehabilitation process.
A brain machine interface (BMI) design for controlling the navigation of a power wheelchair is proposed. Real-time experiments with four able bodied subjects are carried out using the BMI-controlled wheelchair. The BMI is based on only two electrodes and operated by motor imagery of four states. A recurrent neural classifier is proposed for the classification of the four mental states. The real-time experiment results of four subjects are reported and problems emerging from asynchronous control are discussed.

STUDY DESIGN: Cross-sectional survey.
OBJECTIVES: To investigate factors related to length of time between spinal cord injury (SCI) onset and start of first post-injury employment.
SETTING: Persons living with SCI in the community who are members of a disability support organization.
METHODS: Participants were randomly selected from the membership list of a non-governmental voluntary organization. They met the following four criteria: traumatic SCI, minimum of 15 years of age at the time of survey, a minimum of 2 years after SCI and had been employed for some time since SCI. The main outcome measure was time (in years) from injury onset to beginning first post-injury job.
RESULTS: Participants averaged 4.9 years (s.d. 5.1) from the time of SCI to their first post-injury job, with a range of 3 months to 20 years. Fifty percent of the participants who eventually returned to work had done so by 4 years. Return to pre-injury employer and employment were associated with early return, whereas having less years in education and being older at the time of injury were associated with longer time to return to work.
CONCLUSION: Rehabilitation team need to consider return to employment as a realistic goal even many years after SCI. Perhaps a focus on returning more people to their pre-injury employer and employment with added focus and input from rehabilitation team for those with lower education status and older age at time of injury might expedite the process of reintegration.
STUDY DESIGN: Cross-sectional survey.
OBJECTIVES: To determine the employment outcomes of persons with spinal cord injury (SCI) and to investigate the impact of various demographic, injury-related and work-related variables on these outcomes.
SETTING: People living with SCI in Malaysia who are members of a disability support organization.
METHODS: A total of 84 members of the Malaysian Spinal Injury Association, who have had traumatic SCI for at least 2 years and were between 15 and 64 years of age at the time of study, were interviewed through phone using a questionnaire to identify the association between demographic, injury-related and work-related variables and employment outcomes.
RESULTS: The return to work rate in this study was 57.1% (employed at the time of study). The overall employment rate after SCI was 76.2% (worked at some point after injury). Those who were younger at time of injury (<20 years of age), able to drive a modified vehicle, independent in personal care and mobility were positively related to being employed. On the other hand, being hospitalized in the preceding 1 year and receiving financial incentives were negatively related to employment.
CONCLUSION: Functional independence, especially ability to drive, was strongly associated with return to work and should be one of the priority goals of comprehensive rehabilitation of persons with SCI. The negative impact of recent hospitalization as well as financial compensation needs to be probed further.
Conventionally, patellar tendon-bearing (PTB) sockets, which need high dexterity of prosthetist, are widely used. Lack of chartered and experienced prosthetist has often led to painful experience of wearing prosthesis and this will in turn deter the patients to wear the prosthesis, which will further aggravate stump shrinkage. Thus, the hydrostatic socket which demands relatively lower level of fabricating skill is proposed to replace the PTB socket in order to produce the equivalent, if not better, quality of support to the amputee patients. Both sockets' pressure profiles are studied and compared using finite element analysis (FEA) software. Three-dimensional models of both sockets were developed using MIMICS software. The analysis results showed that hydrostatic socket did exhibit more uniform pressure profiles than that of PTB socket. PTB socket showed pressure concentration near the proximal brim of the socket and also at the distal fibula. It was also found that the pressure magnitude in hydrostatic socket is relatively lower than that of PTB socket.
This retrospective study aims to evaluate the effectiveness of the modified regime for rehabilitation of Zone II flexor tendon injuries in Sibu Hospital. From January to December 2003, 8 patients with 15 injured digits were treated by using the combined method of dynamic traction and passive mobilization. According to Strickland's criteria, 14 (93.3%) digits achieved good to excellent outcomes and only 1 (6.7%) was rated as poor. No occurrence of tendon rupture was noted. The overall grip strength of the injured hand was 50.1% of the uninjured hand at 3 months after the repair. Our results compare favorably with the other published studies. We believed that this modified regime is as effective as other established regimes and suitable to be adopted in our setting. Further study with larger sample group will be required to consolidate our findings.
Hearing impairment is one of the most important health problems of the elderly above 60. Very often it leads to verbal communication difficulty and without treatment it can cause serious psychological and social complications such as depression and social isolation. Prebyscusis remains a leading cause of sensorineural deafness in the elderly. Elderly patient must be encouraged to seek proper hearing assessment if they face hearing difficulty. Active screening by health care workers and patient self-evaluation by answering a simple list of screening questions are possible for early detection and treatment of hearing loss in the elderly. Although hearing loss in the elderly may not have a cure, early rehabilitation helps to restore better quality of life if the problem is detected early.
PURPOSE: To determine the extent of rigid contact lens fitting worldwide and to characterize the associated demographics and fitting patterns.
METHODS: Survey forms were sent to contact lens fitters in up to 40 countries between January and March every year for five consecutive years (2007 to 2011). Practitioners were asked to record data relating to the first 10 contact lens fits or refits performed after receiving the survey form. Survey data collected between 1996 and 2011 were also analyzed to assess rigid lens fitting trends in seven nations during this period.
RESULTS: Data were obtained for 12,230 rigid and 100,670 soft lens fits between 2007 and 2011. Overall, rigid lenses represented 10.8% of all contact lens fits, ranging from 0.2% in Lithuania to 37% in Malaysia. Compared with soft lens fits, rigid lens fits can be characterized as follows: older age (rigid, 37.3 ± 15.0 years; soft, 29.8 ± 12.4 years); fewer spherical and toric fits; more bifocal/multifocal fits; less frequent replacement (rigid, 7%; soft, 85%); and less part-time wear (rigid, 4%; soft, 10%). High-Dk (contact lens oxygen permeability) (36%) and mid-Dk (42%) materials are predominantly used for rigid lens fitting. Orthokeratology represents 11.5% of rigid contact lens fits. There has been a steady decline in rigid lens fitting between 1996 and 2011.
CONCLUSIONS: Rigid contact lens prescribing is in decline but still represents approximately 10% of all contact lenses fitted worldwide. It is likely that rigid lenses will remain as a viable, albeit increasingly specialized, form of vision correction.
Osteitis pubis among soccer athletes is a disabling painful condition and it is difficult to manage without integrating a multimodal treatment approach. There is limited scientific evidence on the effectiveness of exercise in treating Osteitis pubis especially when it progress to a chronic painful condition. The purpose of this case report is to discuss the successful multimodal physiotherapeutic management for a 15-year old soccer athlete diagnosed with stage-IV Osteitis pubis. Land and water based active core muscle strengthening exercises, Proprioceptive neuromuscular facilitation techniques (PNF) and Manual Therapy are some of the essential components incorporated in multimodal intervention approach with emphasis to water based strength and endurance training exercises. The athlete was able to make progress to a successful recovery from his chronic painful condition and accomplished the clearly established clinical outcomes during each phase of rehabilitation.
Different suspension systems that are used within prosthetic devices may alter the distribution of pressure inside the prosthetic socket in lower limb amputees. This study aimed to compare the interface pressure of a new magnetic suspension system with the pin/lock and Seal-In suspension systems.
BACKGROUND AND PURPOSE: Social participation restriction is a common barrier encountered by older adults and individuals with physical disabilities. To best direct the limited resource to support social services for individuals with disability, there is a need to objectively measure social participation restriction. A number of tools to measure levels of social participation are available, but none of them has been translated into the Malay language. This cross-sectional study examined the test-retest reliability and concurrent validity of the Life Habits Assessment (LIFE-H 3.1) that had been translated and culturally adapted to the Malay language.
METHODS: Seventy-five individuals with physical disabilities (age, mean [standard deviation] = 58 [10] years; 49 males) participated in this study. Participants were interviewed twice with the Malay version LIFE-H 3.1, approximately 1 week apart. The Barthel Index (BI) and the World Health Organization Assessment of Quality of Life-Brief version (WHOQoL-BREF) were administered in the first interview as well. Intraclass correlation coefficients and the Bland-Altman Bias D were used to examine test-retest reliability. The Spearman correlation coefficients were computed to quantify the correlation between the Malay version LIFE-H 3.1 and the BI and the WHOQoL-BREF, respectively, to examine the concurrent validity of the Malay version LIFE-H 3.1. Furthermore, standard error of measurement and minimal detectable change were calculated.
RESULTS: The Malay version LIFE-H 3.1 had excellent test-retest reliability as evidenced by good to excellent intraclass correlation coefficients (0.71-0.95) and minimal Bland-Altman biases (0.01-0.12). The correlations between the Malay version LIFE-H 3.1 and the BI were fair to good (r = 0.28-0.69). The correlations between the Malay version LIFE-H 3.1 and the WHOQoL-BREF were weak to fair, ranging from 0.02 to 0.57.
CONCLUSIONS: The Malay version LIFE-H 3.1 demonstrates excellent test-retest reliability and satisfactory validity. This questionnaire is an appropriate tool to assess social participation in rehabilitation for native Malay language speakers.
This study examined the factors of successful return to employment among participants in the return to work program (RTW) following work-related injury. Data were obtained from the Social Security Organization database containing 9850 injured workers who underwent RTW in 2010 to 2013. About 65% had successfully returned to employment. Significant factors of successful return include gender, employer interest, motivation, age, intervention duration, and type of injury. Male and motivated employees were more likely to return to employment compared with female and unmotivated employees, respectively. Participants from interested employers were 23.22 times more likely to return to work than those from uninterested employers, whereas participants whose intervention period exceeded 5 months were 41% less likely to return to work compared with those whose intervention period was within 3 months. Appropriate strategy and enhanced collaboration between the stakeholders would improve the proportion of successful return to employment.

INTRODUCTION: In a previous study consensus was sought from Malaysian occupational therapists of occupation-based intervention (OBI) that was perceived as a means and an end. Occupation as a means refers to occupational and purposeful tasks as a therapeutic agent while occupation as an end refers to occupation as an outcome of intervention. The purpose of this follow-up study was to describe the occupational therapists' experiences of providing OBI in hand injury rehabilitation in Malaysia.
METHODS: Sixteen occupational therapists with more than five years of experience in hand rehabilitation were individually interviewed on their experiences of using OBI in practice. Data were thematically analysed using interpretative phenomenological analysis.
RESULTS: Definition of "Occupation as a means", and "Occupation as an end" was broadened after data analysis of interviews to include two new themes: "Rewarding yet challenging" and "Making OBI a reality". Occupational therapists had positive experiences with OBI and perceived that occupation as a means and an end can be merged into a single therapy session when the occupational therapists use an occupation that is therapeutic.
CONCLUSION: Although occupation as a means and as an end have different purposes, when the ultimate goal is to enhance the clients' maximum level of functioning both can be used for successful rehabilitation of hand injuries.
