Lumbar disc degeneration in Thai elderly: a population-based study.

OBJECTIVE: Determine the prevalence and related factors of lumbar disc degeneration in the Thai elderly. MATERIAL AND METHOD: A population-based study was done at Rom Klao community, Bangkok. Seven hundred and ninety-two cases (306 males, and 486 females) out of 1166 elderly people aged > or =50 (mean age of 61.07 +/- 7.8 years) were assessed. The lateral spinal radiographs were interpreted as spondylosis grade 0-3 according to the degree of severity. RESULTS: Males had more prevalence of grade 2-3 spondylosis than females (58.8% vs. 52.9%), but females had higher prevalence of spinal listhesis (14.4% vs. 8.8%). Age was a strong predicting factor for disc degeneration (OR = 1.088, 95% CI = 1.065-1.111, p = 0.000). Females had more risk to develop spinal listhesis (OR = 1.84, 95% CI = 1.11-3.05, p = 0.020) and low back pain (OR = 1.82, 95% CI = 1.29-2.56, p = 0.001). BMI was a predicting factor for spondylosis (OR = 1.066, 95% CI = 1.02-1.10, p = 0.000). About 27% of the cases reported moderate-severe low back pain and had lower Barthel ADL index (p = 0.018). CONCLUSION: Lumbar disc degeneration and low back pain were highly prevalent among the Thai elderly. Therefore, they need proper health care for disability prevention.

Falls among stroke patients in Thai Red Cross rehabilitation center.

OBJECTIVE: To determine the incidence and risk factors of falls among stroke patients. MATERIAL AND METHOD: A prospective cohort study was designed to study the stroke patients who were admitted to the Thai Red Cross Rehabilitation Center from February 2004 to July 2005. Related variables offaller and non-faller groups were compared. RESULTS: Of 151 patients, 24 (15.9%) experienced at least one fall. The incidence rate was 3.44/1000 patients/ day. Most of the falls (71.4%) occurred during the daytime, in the bathroom (37.1%), and by the bedside (22.9%). Falls frequently occurred while transferring (22.9%) and walking (20%). Barthel ADL Index (BAI) score was the variable that significantly differentiated the fallers from the non-fallers (p = 0.013). Patients with BAI score of > or = 12 had 3 times more risk to fall. CONCLUSION: About 16% of stroke patients fell during rehabilitation. More attention should be paid during the transfer and ambulation. Furthermore, a safety area should be provided in every bathroom and by the bedside.
