Impact, distress and HRQoL among Malaysian men and women with a mobility impairment.

BACKGROUND: Although non-communicable and chronic disease now accounts for 47% of the global burden of disease, little is known of the everyday experiences and social aspects of disability and disablement in middle and low income countries. This article aims to address this gap by exploring the subjective experience of mobility impairment in Malaysia. Specifically, it examines health-related quality of life and the impact and distress related to impaired mobility, and investigates any gender differences in relation to the experience of disability. METHODS: The data were collected as part of an interdisciplinary, multi-country study known as RESILIENCE (Research into Social Inclusion, Locomotive Impairment and Empowerment through Networking, Collaboration and Education). Cluster sampling was used to administer the EQ-5D and the Perceived Impact of Problems Profile (PIPP) to 210 adults from Selangor state, west coast Peninsular Malaysia. RESULTS: The participants consisted of 94 males and 116 females, aged between 18-90 years (mean 60 years), with the majority being Malay. The majority of participants were also married, from rural areas and had primary education only. Very few participants lived alone. In addition, males were more likely to attribute their impaired mobility to an accident. The majority of participants with mobility impairment experienced a moderate to high level of pain/discomfort (79%) and anxiety/depression (72%), and at least some problems with performing usual activities (71%), as measured by the EQ-5D. In addition, using the Perceived Impact of Problems Profile (PIPP), participants also reported high levels of impact and distress related to participation in community life. In general, males reported higher impact and distress across several items, most significantly in regard to participation in community activities, moving around the neighbourhood, ability to live independently, and ability to assist their family members. CONCLUSION: This paper provides preliminary data regarding the health-related quality of life among Malaysians with impaired mobility, and highlights the multifaceted impact of disability and the importance of acknowledging the diverse cultural contexts in which disability can occur. It also raises questions regarding gender differences in the subjective experience of disability in Malaysia.

Median and Ulnar 14-cm Antidromic Sensory Studies to the Third and Fifth Digits-A Comparison of Amplitude.

There are multiple reports of peripheral nerve injury following the implantation or removal of surgical hardware. Electrodiagnostic testing can be useful in assessing the chronicity, severity, and recovery of such a nerve injury. The purpose of this study is to establish a normative data set to allow for comparison of median and ulnar antidromic sensory peak-to-peak amplitude values. Median and ulnar antidromic sensory studies to digits 3 and 5 are commonly performed in electrodiagnosis to aid in the diagnosis of a variety of clinical conditions. Numerous studies have examined normal latency and amplitude values for these studies. To our knowledge there has been one other study that compared the relationship between median and ulnar sensory amplitude results taken from the same limb. That study had limited generalizability to the population at large. One hundred-nineteen volunteers were tested with antidromic sensory technique to digits 3 and 5 at 14-cm stimulation distance. Peak latency and peak-to-peak amplitude were recorded. Possible relationships between age, gender, height, weight, BMI, and median and ulnar amplitude were examined through simple linear regressions. Age, weight, height, and BMI were all found to negatively correlate with both median and ulnar amplitude. Female subjects were found to have statistically greater median and ulnar amplitudes than male subjects. Factors were said to be statistically significant at the P </= 0.05 level. The mean median peak latency was 3.2 +/- 0.3 ms. The mean ulnar peak latency was 3.2 +/- 0.4 ms. The mean median peak-to-peak amplitude was 87 +/- 36 muV. The mean ulnar peak-to-peak amplitude was 72 +/- 34 muV. The upper limit of normal difference (2.5th percentile) in median-versus-ulnar amplitude was a 56% drop from median-to-ulnar amplitude, or a 59% drop from ulnar-to-median amplitude. This allows for amplitude comparisons to be made between these two nerves.

Identifying the concepts contained in outcome measures of clinical trials on stroke using the International Classification of Functioning, Disability and Health as a reference.

OBJECTIVES: To systematically identify and quantify the concepts contained in outcome measures in stroke trials using the International Classification of Functioning, Disability and Health (ICF) as a reference. METHODS: Randomized controlled trials between 1992 and 2001 were located in MEDLINE and selected according to predefined criteria. Outcome measures were extracted and concepts contained in the outcome measures were linked to the ICF. RESULTS: A random sample of 160 (50%) of 320 eligible studies was included. A total of 148 standardized health status measures were identified. Of 11,283 extracted concepts, 91% could be linked to the ICF. The most used ICF categories for each component were d450 walking (70%) for activities and participation, b525 defecation functions (62%) for body functions, and e399 support and relationships, unspecified (30%) for environmental factors. CONCLUSION: The ICF provides a useful reference to identify and quantify the concepts contained in outcome measures used in stroke trials. Outcome measurement in stroke refers to an enormous variety of concepts; for comparability of research findings agreement on what should be measured is needed.

ICF Core Sets for stroke.

OBJECTIVE: To report on the results of the consensus process integrating evidence from preliminary studies to develop the first version of the Comprehensive ICF Core Set and the Brief ICF Core Set for stroke. METHODS: A formal decision-making and consensus process integrating evidence gathered from preliminary studies was followed. Preliminary studies included a Delphi exercise, a systematic review, and an empirical data collection. After training in the ICF and based on these preliminary studies relevant ICF categories were identified in a formal consensus process by international experts from different backgrounds. RESULTS: The preliminary studies identified a set of 448 ICF categories at the second, third and fourth ICF levels with 193 categories on body functions, 26 on body structures, 165 on activities and participation, and 64 on environmental factors. Thirty-nine experts from 12 different countries attended the consensus conference on stroke. Altogether 130 second-level categories were included in the Comprehensive ICF Core Set with 41 categories from the component body functions, 5 from body structures, 51 from activities and participation, and 33 from environmental factors. The Brief ICF Core Set included a total of 18 second-level categories (6 on body functions, 2 on body structures, 7 on activities and participation, and 3 on environmental factors). CONCLUSION: A formal consensus process integrating evidence and expert opinion based on the ICF framework and classification led to the definition of ICF Core Sets for stroke. Both the Comprehensive ICF Core Set and the Brief ICF Core Set were defined.

ICF Core Sets for diabetes mellitus.

OBJECTIVE: To report on the results of the consensus process integrating evidence from preliminary studies to develop the first version of a Comprehensive ICF Core Set and a Brief ICF Core Set for diabetes mellitus. METHODS: A formal decision-making and consensus process integrating evidence gathered from preliminary studies was followed. Preliminary studies included a Delphi exercise, a systematic review, and an empirical data collection. After training in the ICF and based on these preliminary studies relevant ICF categories were identified in a formal consensus process by international experts from different backgrounds. RESULTS: The preliminary studies identified a set of 253 ICF categories at the second, third, and fourth ICF levels with 99 categories on body functions, 40 on body structures, 55 on activities and participation, and 59 on environmental factors. Fifteen experts attended the consensus conference on diabetes mellitus (8 physicians with various sub-specializations; 5 physical therapists, one epidemiologist and one social worker). Altogether 99 categories (85 second-level and 14 third-level categories) were included in the Comprehensive ICF Core Set with 36 categories from the component body functions, 16 from body structures, 18 from activities and participation, and 29 from environmental factors. The Brief ICF Core Set included a total of 33 second-level categories with 12 on body functions, 6 on body structures, 5 on activities and participation, and 10 on environmental factors. CONCLUSION: A formal consensus process integrating evidence and expert opinion based on the ICF framework and classification led to the definition of ICF Core Sets for diabetes mellitus. Both the Comprehensive ICF Core Set and the Brief ICF Core Set were defined.
