Measuring mobility in frail older people: reliability and validity of the Physical Mobility Scale

Objectives: The study was designed to show the validity and reliability of scoring the Physical Mobility Scale (PMS). PMS was developed by physiotherapists working in residential aged care to specifically show resident functional mobility and to provide information regarding each resident's need for supervision or assistance from one or two staff members and equipment during position changes, transfers, mobilising and personal care. Methods: Nineteen physiotherapists of varying backgrounds and experience scored the performances of nine residents of care facilities from video recordings. The performances were compared to scores on two 'gold standard' assessment tools. Four of the physiotherapists repeated the evaluations. Results: The PAIS showed excellent content validity and reliability. Conclusions: The PAIS provides graded performance of physical mobility, including level of dependency on staff and equipment. This is a major advantage over existing functional assessment tools. There is no need for specific training for physiotherapists to use the tool.

Efficacy of B vitamins in lowering homocysteine in older men - Maximal effects for those with B-12 deficiency and hyperhomocysteinemia

Background and Purpose - A higher plasma concentration of total homocysteine (tHcy) is associated with a greater risk of cardiovascular events. Previous studies, largely in younger individuals, have shown that B vitamins lowered tHcy by substantial amounts and that this effect is greater in people with higher tHcy and lower folate levels. Methods - We undertook a 2-year, double-blind, placebo-controlled, randomized trial in 299 men aged >= 75 years, comparing treatment with a daily tablet containing 2 mg of folate, 25 mg of B-6, and 400 mu g of B-12 or placebo. The study groups were balanced regarding age (mean +/- SD, 78.9 +/- 2.8 years), B vitamins, and tHcy at baseline. Results - Among the 13% with B12 deficiency, the difference in mean changes in treatment and control groups for tHcy was 6.74 mu mol/L (95% CI, 3.94 to 9.55 mu mol/L) compared with 2.88 mu mol/L (95% CI, 0.07 to 5.69 mu mol/L) for all others. Among the 20% with hyperhomocysteinaemia, the difference between mean changes in treatment and control groups for men with high plasma tHcy compared with the rest of the group was 2.8 mu mol/L (95% CI, 0.6 to 4.9 mu mol/L). Baseline vitamin B12, serum folate, and tHcy were significantly associated with changes in plasma tHcy at follow-up (r = 0.252, r = 0.522, and r = -0.903, respectively; P = 0.003, <0.001, and <0.001, respectively) in the vitamin group. Conclusions - The tHcy-lowering effect of B vitamins was maximal in those who had low B12 or high tHcy levels. Community-dwelling older men, who are likely to be deficient in B12 or have hyperhomocysteinemia, may be most likely to benefit from treatment with B vitamins.

Measuring outcomes of a communication program for older people with hearing impairment using the International Outcome Inventory

The main objective of this study was to describe the outcomes of a communication education program for older people with hearing impairment using the International Outcome Inventory - Alternative Interventions (IOI-AI) and the version for significant others (IOI-AI-SO). Ninety-six people aged 58 to 94 years participated in an interactive group education program for two hours per week for five weeks. The IOI-AI was administered at one to two weeks after the last educational session and 29 significant others also completed the IOI-Al-SO at this time. Overall, positive results were obtained using both questionnaires, and satisfaction with the program was particularly high. Findings also compared favourably to reports of outcomes for other audiological interventions (i.e., another communication training program and hearing aid fitting). Principal components analysis of the IOI-AI revealed a somewhat different factor structure than the original IOI-HA. The two versions of the 101 applied in this study are recommended as simple and effective measures of the outcomes of alternative interventions.

Social communication in older age: Lessons from people with aphasia

Lessons on social communication in older age are drawn from the stories and qualitative case reports of three older people who have aphasia following stroke. Descriptive accounts of participant responses to qualitative interviews and stimulated recall of natural conversations, together with information from a social network diary, provide evidence of aspects of social communication relevant to the older person with aphasia. The perspectives of individuals and common themes relating to social communication with family and friends, the experience of aphasia, and living with aphasia in older age are presented. The prominence of conversations and the role of storytelling and of humor within the daily social communication of older people are illuminated. Key words: aphasia, older people, social communication
