Summary
Biofeedback training significantly improves orthopedic patient adherence to weight-bearing instructions across all age groups. This method is more effective than verbal cues or bathroom scales for ensuring proper limb loading.
Area of Science:
- Orthopedics
- Rehabilitation Medicine
- Biomedical Engineering
Background:
- Partial weight-bearing is crucial for orthopedic recovery.
- Previous studies showed biofeedback effective in younger populations.
- The impact of age on biofeedback training for weight-bearing compliance was unknown.
Purpose of the Study:
- To evaluate the effect of age on partial weight-bearing training using biofeedback.
- To compare the efficacy of biofeedback, bathroom scales, and verbal instructions for weight-bearing compliance.
Main Methods:
- Fifty healthy participants (20-78 years) underwent three interventions: verbal instructions, bathroom scale training, and biofeedback device training.
- Weight-bearing was measured for both touchdown (25 lb) and partial (75 lb) weight-bearing instructions.
- Mixed-model analysis was used to assess the influence of age, body mass index, and sex on compliance.
Main Results:
- Biofeedback training significantly improved weight-bearing compliance compared to verbal instructions or bathroom scales for both weight-bearing levels.
- Verbal instructions alone resulted in significantly higher weight-bearing than prescribed.
- Age was not a significant factor in compliance, but higher BMI and male sex predicted worse compliance.
Conclusions:
- Biofeedback training is a superior method for enhancing weight-bearing compliance in orthopedic patients.
- The effectiveness of biofeedback training is consistent across different age groups.
- Biofeedback should be considered for all orthopedic patients requiring weight-bearing adherence training.

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are not...
01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...
