Comparison of self-reported ability to perform Kegel's exercise pre- and post-coital penetration in postpartum women.

We compared the self-reported ability to perform Kegel's exercises pre- and post-coital penetration in postpartum women. A cross-sectional design. Twenty-seven postpartum women with mild urinary incontinence were recruited.

Effects of Diaphragmatic Breathing Exercise on Respiratory Functions and Vocal Sustenance in Apparently Healthy Vocalists.

Background: Effective vocalization is dependent on breathing efficiency. Previous studies have reported the efficacy of Diaphragmatic Breathing Exercise (DBE) on the respiratory muscles and breath control of vocalists. There is a paucity of data on the effects of DBE on their vocal sustenance (VS), which is determined as Maximum Phonation Time (MPT).

Determining safe teaching board heights through electromyographic analysis of the shoulder muscles.

Background: Adjustable teaching boards have been recommended as an ergonomic practice geared at reducing the incidences of teaching-related shoulder musculoskeletal disorders among teachers. However, there are no standards guiding choice of appropriate teaching board heights. This study was aimed at evaluating shoulder muscle activities in response to five teaching board heights.

Biomechanical analysis of the three recommended breastfeeding positions.

Background: For maternal and infant benefits, cradle, cross-cradle and football hold positions have been recommended and widely utilized by mothers during breastfeeding (BF) tasks. There is paucity of data on the biomechanical costs of these BF positions.

Objective: This study evaluated the trunk lean angles and electromyographic (EMG) activities of the trunk muscles during these BF positions.

Evaluation of selected cardiopulmonary and perceived exertion responses to four infant carrying methods utilised by African Mothers.

Various infant carrying methods (ICMs) are utilised for childcare. Effects of these ICMs on the cardiopulmonary system are not known. This study evaluated cardiopulmonary and perceptual responses to four ICMs (back, front, side and in-arms) among 30 young females (18-35 years) while walking with a 6 kg simulated infant.

Prevalence, pattern and correlates of work-related musculoskeletal disorders among school teachers in Enugu, Nigeria.

. There is insufficient literature on the prevalence of and risk factors for work-related musculoskeletal disorders (MSDs) among teachers in Nigeria. This study aimed to investigate the prevalence of work-related MSDs and their associations with occupational and socio-demographic factors of Nigerian-based school teachers.

Prevalence and associated factors of work related musculoskeletal disorders among commercial milling machine operators in South-Eastern Nigerian markets.

Background: Milling machine operators perform physically demanding tasks that can lead to work related musculoskeletal disorders (WRMSDs), but literature on WRMSDs among milling machine operators is scarce. Knowledge of prevalence and risk factors of WRMSDs can be an appropriate base for planning and implementing ergonomics intervention programs in the workplace.

Objective: This study aimed to determine the prevalence, pattern and associated factors of WRMSDs among commercial milling machine operators in Enugu, Nigeria.

Infant carrying methods: Correlates and associated musculoskeletal disorders among nursing mothers in Nigeria.

Infant carrying is an integral part of the mothering occupation. Paucity of data exists on its correlates and associated musculoskeletal injuries. In this study, factors and musculoskeletal injuries associated with infant carrying were investigated in 227 nursing mothers, using a structured questionnaire.
