“…The trunk holding test (also known as “Sørensen back endurance test”) is widely used by clinicians. On the other hand, power spectral analysis of surface electromyographic (EMG) recording has indicated that muscle fatigue is associated with shifts in the median frequency (MF) toward lower values [17‐21]. Ng and Richardson [22] indicated that the trunk holding test combined with EMG power spectral analysis is a reliable method to measure the fatigue rate of paraspinal muscles.…”

“…Additional work is needed to identify the characteristics of each movement in order to create general posture modeling for each movement. Since there is not enough evidence regarding EMG differences according to age and gender (Anderson et al, 1984;Tsuboi et al, 2013;Vaiman et al, 2004;Youdas et al, 2007;Zeller et al, 2003), further research is needed to investigate the EMG data for various horticultural activities based on age or gender. This analysis may be used to generate biomechanical profiles of gardening tasks for practitioners when designing efficient interventions for physical health or rehabilitation.…”

Movements of the upper and lower limb muscles during five common gardening tasks were analyzed by using electromyography (EMG). Twenty adults aged in their twenties (mean age, 24.8 ± 2.4 years) were recruited. On two separate occasions, subjects visited a garden plot to perform digging, raking, troweling, weeding, and hoeing; all tasks were performed three times with 20 s intervals for each trial. To measure muscle activation during the five gardening tasks, surface EMG was used. Bipolar surface EMG electrodes were attached to eight upper limb muscles (bilateral anterior deltoid, biceps brachialis, brachioradialis, and flexor carpi ulnaris) or eight lower limb muscles (bilateral vastus lateralis, vastus medialis, biceps femoris, and gastrocnemius) on both sides of the body, for a total of 16 muscles. During the five tasks, photographs were taken of movement phases using a digital video camera. The right flexor carpi ulnaris and brachioradialis showed higher activation than the other upper and lower limb muscles measured during the tasks. All 16 upper and lower limb muscles were actively used only during digging. According to movement analysis of each activity, digging was classified into four movement phases, whereas raking, troweling, weeding, and hoeing each were divided into three movement phases. In each activity, there were high-impact phases in terms of muscle activation; the flexor carpi ulnaris and brachioradialis were identified as major muscles in each impact phase. This analysis may be used to generate biomechanical profiles of gardening tasks for practitioners when designing efficient gardening interventions for physical health or rehabilitation.

“…72 Both clinical testing and electromyographical indices of fatigue indicate that low back pain populations have a reduction in erector spinae muscle endurance. 67,73 Therapeutic interventions that focus on improving endurance (high repetitions at low loads) of the erector spinae and multifidus muscles have been recommended for improved functional outcomes in patients with lumbar instability and muscle hypertrophy. [74][75][76] Whilst others have suggested that an exercise intensity of at least 65-70% of a single maximum exertion is necessary to recruit all muscle fibre types and develop erector spinae muscle hypertrophy.…”

Background: Lumbar posture has a significant impact on the functional biomechanics of the erector spinae and multifidus muscles, which has implications for the loads placed on the tissues of the lumbar spine. Objectives: The objective of this review is to discuss the effects of lumbar posture on the functional biomechanics of the different divisions of the erector spinae and the multifidus muscle and its importance when developing clinical interventions.Methods: This review used the search engines PubMed, EBSCO, CINAHL and SCOPUS to identify studies investigating erector spinae and multifidus muscle architecture and the influence of lumbar posture on the biomechanical properties of these muscles and the resulting impact on spinal loading. Results: Changes in lumbar curvature alter muscle fascicle obliquity, lever arm distances, the length-tension relationships and muscle volume of the different divisions of erector spinae and multifidus, which impact on the spine's ability to resist moments and shear forces. Conclusion: Changes in lumbar posture influence the functional biomechanics of the different divisions of erector spinae and the multifidus muscles. Therapists should develop low back interventions that avoid end range of lumbar postures and optimise the functional biomechanics of the erector spinae and multifidus muscles and minimise loading on the lumbar spine.
