Influence of age on lifting capacity among manual materials handlers.

Background: Recommended weight limit for manual materials handlers has to be decided based on the individual characteristics of the person and age is one of the major variable affecting maximal lifting capacity. But there is limited information on pattern of change in lifting capacity with age.

Objective: To determine the influence of age on the maximum acceptable weight of lift among manual materials handlers.

Safety management practices in small and medium enterprises in India.

Background: Small and medium enterprises (SMEs) are often the main pillar of an economy. Minor accidents, ergonomics problems, old and outdated machinery, and lack of awareness have created a need for implementation of safety practices in SMEs. Implementation of healthy working conditions creates positive impacts on economic and social development.

Evaluation of the working posture and prevalence of musculoskeletal symptoms among medical laboratory technicians.

Background: Technological advancement in the medical laboratories has exposed the laboratory technicians to various ergonomic hazards due to nature of their work.

Objective: The study aimed to analyze the working postures, to find out the prevalence of work related musculoskeletal disorders and to investigate the relationship between musculoskeletal disorders with individual factors, work characteristics and the working postures.

Methods: The study was conducted among 60 medical laboratory technicians.

A study of subjective visual disturbances in jewellery manufacturing.

Subjective Visual Disturbances are silent adversaries that appear over a period of continued exposure and arise when the visual demands of the tasks exceed the visual abilities of the user. Jewellery manufacturing activity involves precision designs, setting the metal and stones, polishing and filing which requires higher visual demand. Therefore, it is expected that the jewellery manufacturing workers may experience subjective visual disturbances.

Study on lumbar kinematics and the risk of low back disorder in female university students by using shoes of different heel heights.

The study was taken up to investigate the effects of heel heights on lumbar kinematics and the risk of Low Back Disorder (LBD) in females. Nineteen female university students (24.5 ± 3.

Effect of exercise and heat-load on simple reaction time of university students.

Visual and auditory simple reaction times for both right and left hands of young university male students were recorded with a simple reaction timer, before and after an exercise schedule without and with elevated temperatures in a climatic chamber. The results indicated a decrease in both visual and auditory reaction times after the exercise, but a marked increase in them was noticed when exercise was performed at elevated temperatures. The difference in reaction times in preferred and nonpreferred hands was negligible at rest, i.

A comparative assessment of the impact of different occupations on workers' static musculoskeletal fitness.

An ergonomic assessment of the involvement of static muscular forces like back strength, grip strength and pinch strength in different occupations was made. A study was conducted on 45 normal adult males (15 subjects per group) which included video display terminal (VDT) operators, industrial workers and safety inspectors. Their maximum back strength, handgrip strength and pinch strength were measured with dynamometers.
