Increasing postural sway in rural-community-dwelling elderly persons with knee osteoarthritis

Objective Risk factors for falling in elderly people remain uncertain, and the effects of spinal factors and physical ability on body balance and falling have not been examined. The objective of this study was to investigate how factors such as spinal sagittal alignment, spinal range of motion, body balance, muscle strength, and gait speed influence falling in the prospective cohort study. Methods The subjects were 100 males who underwent a basic health checkup. Balance, SpinalMouse Ò data, grip strength, back muscle strength, 10-m gait time, lumbar lateral standing radiographs, body mass index, and fall history over the previous year were examined. Platform measurements of balance included the distance of movement of the center of pressure (COP) per second (LNG/TIME), the envelopment area traced by movement of the COP (E AREA), and the LNG/E AREA ratio. The thoracic/lumbar angle ratio (T/L ratio) and sagittal vertical axis (SVA) were used as an index of sagittal balance. Results LNG/TIME and E AREA showed significant positive correlations with age, T/L ratio, SVA, and 10-m gait time; and significant negative correlations with lumbar lordosis angle, sacral inclination angle, grip strength and back muscle strength. Multiple regression analysis showed significant differences for LNG/TIME and E AREA with T/L ratio, SVA, lumbar lordosis angle and sacral inclination angle (R 2 = 0.399). Twelve subjects (12 %) had experienced a fall over the past year. Age, T/L ratio, SVA, lumbar lordosis angle, sacral inclination angle, grip strength, back muscle strength, 10-m gait time, height of the intervertebral disc, osteophyte formation in radiographs and LNG/E AREA differed significantly between fallers and non-fallers. The group with SVA [ 40 mm (n = 18) had a significant higher number of subjects with a single fall (6 single fallers/18: p = 0.0075) and with multiple falls (4 multiple fallers/18: p = 0.0095). Conclusion Good spinal sagittal alignment, muscle strength and 10-m gait speed improve body balance and reduce the risk of fall. Muscle strength and physical ability are also important for spinal sagittal alignment. Body balance training, improvement of physical abilities including muscle training, and maintenance of spinal sagittal alignment can lead to prevention of fall.

“…This disease is also a major cause of pain and disability in most countries of the world (2,7), and affects all age groups (3), so that it was prevalent in males before 45 years old and in femlaes at 55 years old and its prevalence increases with age in both genders (8). Also it is one of the important reasons for the decline in activities of daily living and low quality of life in older people (9), and has a significant impact on the lives of individuals, including mobility, independence and everyday activities and leads to a restriction of recreational, sport and occupational activities (10).…”

Background: Knee osteoarthritis is the most common type of arthritis and musculoskeletal disease. Due to low efficacy and significant side effects of synthetic drugs in the treatment of this disease, many researchers are looking for drugs that besides effectiveness have fewer side effects, and recently ginger has become one of the most popular herbal remedies in the treatment of this disease in controversial researches.

“…Knee osteoarthritis (OA), one of the most common chronic health conditions, is associated with significant impairment and disability (3), and predominantly affects the elderly population (4). Previous studies have shown that those with knee OA exhibit worse standing balance, typically quantified using posturography or center of pressure (COP) movement obtained from a force platform, than those of a similar age without OA (5)(6)(7)(8). Importantly, the relevance of these findings has been confirmed in the clinical setting by Swinkels et al (9), who recently reported that 24% of patients on a knee replacement waiting list experienced a fall prior to surgery.…”

Objective. To identify factors related to single-leg standing balance in individuals with medial compartment knee osteoarthritis (OA). Methods. This cross-sectional study assessed clinical, demographic, and biomechanical measures in 57 individuals and their relationships with single-leg standing balance. Differences in age, mass, symptoms, knee pain, radiographic severity, lower extremity alignment, and hip and knee extension as well as hip abduction torques were compared between those who could and could not perform 3 trials of single-leg standing balance. Multiple regression was used to identify predictors of center of pressure (COP) path length in those who could complete the task. Results. Thirty-four individuals (60%) successfully completed all 3 single-leg standing balance trials and were significantly younger (P ‫؍‬ 0.003) than those who could not. No other variable was significantly different between the groups. Disease severity, number of painful knees, lower extremity alignment, pain intensity, and quadriceps torque were all significant predictors of COP path length. Specifically, better single-leg standing balance (smaller COP path length) was related to more severe radiographic changes and stronger quadriceps, those with bilateral symptoms, and to less varus malalignment and knee pain. Conclusion. Single-leg standing balance in those with medial knee OA is related to the modifiable factors lower extremity alignment, knee pain, and quadriceps strength. Given the reduced balancing ability in this patient population, interventions targeting these factors are necessary.
