Tactile discrimination, but not tactile stimulation alone, reduces chronic limb pain

Abstract: Chronic pain is often associated with reduced tactile acuity. A relationship exists between pain intensity, tactile acuity and cortical reorganisation. When pain resolves, tactile function improves and cortical organisation normalises. Tactile acuity can be improved in healthy controls when tactile stimulation is associated with a behavioural objective. We hypothesised that, in patients with chronic limb pain and decreased tactile acuity, discriminating between tactile stimuli would decrease pain and increase tactile acuity, but tactile stimulation alone would not. Thirteen patients with complex regional pain syndrome (CRPS) of one limb underwent a waiting period and then approximately 2 weeks of tactile stimulation under two conditions: stimulation alone or discrimination between stimuli according to their diameter and location. There was no change in pain (100 mm VAS) or two-point discrimination (TPD) during a no-treatment waiting period, nor during the stimulation phase (p > 0.32 for both). Pain and TPD were lower after the discrimination phase [mean (95% CI) effect size for pain VAS = 27 mm (14-40 mm) and for TPD = 5.7 mm (2.9-8. ), p < 0.015 for both]. These gains were maintained at three-month follow-up. We conclude that tactile stimulation can decrease pain and increase tactile acuity when patients are required to discriminate between the type and location of tactile stimuli.

A community‐based exercise programme to improve functional ability in people with Alzheimer’s disease: a randomized controlled trial

Abstract: Scand J Caring Sci; 2012; 26; 12–19 A community-based exercise programme to improve functional ability in people with Alzheimer’s disease: a randomized controlled trial Rationale: Dementia is a common neurodegenerative condition in older age associated with functional decline across multiple domains. This decline impacts not only on the person with dementia, but also on their informal carers and health and aged care systems. With the number of people with dementia rapidly increasing and few effective treatments, there is now a critical need for interventions to improve functional ability in those with the condition. Aims and objective: This study assesses the effectiveness of a community-based home exercise programme in improving cognitive and physical function and independence in activities of daily living (ADL) in people with Alzheimer’s disease, the most common form of dementia. Methods: In a 4-month randomized controlled trial, 40 community-dwelling patients diagnosed with Alzheimer’s disease and their informal carers were randomly allocated to either the treatment (exercise plus usual treatment) or control (usual treatment) group. The exercise programme consisted of daily exercises and walking under the supervision of their carer. Patients were assessed at baseline and 4-months follow-up by a blinded assessor on primary outcome measures of cognitive and physical function and ADL using standardized assessment scales. Results: Sixteen men and 24 women diagnosed with Alzheimer’s disease participated in the study. They had a mean age of 74.1 years (range 51–89) and a mean Mini Mental State Examination score of 22.0 (range 10–28), indicating mild to moderate dementia. At 4-months follow-up, patients who exercised, compared with controls, had improved cognition (increased Mini Mental State Examination scores by 2.6 points, p < 0.001), better mobility (2.9 seconds faster on Timed Up and Go, p = 0.004) and increased Instrumental Activities of Daily Living scores by 1.6 (p = 0.007). Conclusion: This study suggests that participation in a community-based exercise programme can improve cognitive and physical function and independence in ADL in people with Alzheimer’s disease.
