Acute effect of precise manual tasks on physiological tremor of both upper limbs in young and elderly people

Key Points

• Physiological tremor increases in both young and elderly individuals during repetitive work tasks, indicating muscle fatigue.
• The study shows measurable tremor changes linked to manual tasks, highlighting fatigue's impact across age groups.
• Assessment using physiological tremor measurements provides insights into muscle fatigue during manual activities.
• Findings suggest that understanding tremor can improve efficiency in evaluating job-related fatigue and adaptive capabilities.
