A Patient’s Guide to Trigger Points
Published in Michael S. Margoles, Richard Weiner, Chronic PAIN, 2019
Weakness and restricted motion in the involved muscle. When maximum effort (of contraction) is attempted, there is less than normal strength. Muscle strength is unreliable due to the guarding action of the TrP. The person may drop things, like when trying to put a carton of milk away. Another example is encountered when working in the yard. There is a sudden low back pain, bringing the person to the ground. They cannot get up due to the pain. The ambulance whisks them away to the emergency room, where X-rays and such are negative. They are sent home with a pain medicine and muscle relaxant and told they will be better in a few days. Low back strain is the common diagnosis, and unsatisfactory treatment results ensue.
Posture and orthopedic impairments

A condition called ptosis is often associated with lordosis and is caused by a weakness, sagging, or total collapse of the abdominal muscles. Muscle groups in the abdominal region should be strengthened to counteract this condition and alleviate some aspects of lordosis, using the following exercises: In a sitting position, with bent knees, fold hands across the chest and curl up toward knees; hold and return. If muscle groups are extremely weak, lift the head and shoulders, leaving the small of the back on the floor to prevent back strain.In a hanging or sitting position, bring both knees up slowly as far as possible and return.Lying supine, flutter kick legs, or flutter kick in an aquatic setting.
The back

Transient backache following muscular activity This suggests a simple back strain that will respond to a short period of rest followed by gradually increasing exercise. People with thoracic kyphosis (of whatever origin), or fixed flexion of the hip, are particularly prone to back strain because they tend to compensate for the deformity by holding the lumbosacral spine in hyperlordosis.
Influence of load knowledge on lifting biomechanics

As expected, increased load weight resulted in increased lower back load during lifting. As lower back load is a direct indicator of LBD risks [20], this confirmed that load weight was a risk factor for LBD. An interesting finding is that when lifting high load weight versus low load weight, people adopted a posture with larger elbow flexion, shoulder flexion, hip flexion and ankle plantar flexion at the ending posture. This ending posture of elbow and shoulder joints would lead to decreased horizontal distance between the lifting load and the lower back. The horizontal distance between the lifting load and the lower back defines the load moment arm at the lower back. Thus, the lower back load would be lowered with the smaller horizontal distance between the lifting load and the lower back. A previous study also reported that larger flexion angles of upper extremities can have a biomechanical advantage to reduce the lower back strain in the lifting task [23]. Additionally, for the ending posture, the increased hip flexion and increased ankle plantar flexion when a heavier load weight was lifted indicated that lower extremities had a coordination pattern of antiphase rotations. This implies that participants could adjust hip and ankle postures to control their balance during lifting tasks [23]. The aforementioned findings imply that people may be able to adopt a protective postural control strategy during lifting to compensate for the adverse effects of increased load weight on lower back load.
Prevalence, patterns and factors associated with injury: comparison between elite Malaysian able-bodied and para-badminton players

Among para-badminton players, the average age of injured players was higher compared to their able-bodied counterparts as the former were generally older. However, similar to able-bodied players, more injuries were found in males [27,28]. Among the standing-class players, the patterns of injury for all body regions were similar to those for able-bodied badminton players and other para standing-class sports such as volleyball and football [6,7,9,32]; hence, a similar mechanism may be involved. On the other hand, for wheelchair players, upper limb injuries particularly to the shoulder were commonest, which could be associated with improper conditioning and repetitive use [33]. With regard to lower limb injury for this group, foot calluses were commonly observed, which are possibly due to constant friction to the shoe edge [34]. As for the torso, lower back strain was most prevalent, and this can be attributed to the strength imbalance associated with prolonged sitting [35]. For para-badminton players, most injuries were found to be overuse in nature, which could be associated with their body impairments and the continuous demands placed on the body by the activities of daily living and sports [36].
Low-impact (compliant) flooring and staff injuries
Published in Disability and Rehabilitation, 2022
H. C. Hanger, Tim J. Wilkinson
In this trial, there were three different LIFs installed. Each has different compliance and rolling resistance characteristics, and we cannot exclude that one type of flooring might be worse from a staff point of view than others. Further limitations are the relatively small number of staff injuries and the de-identified data does not allow examination of the age, gender or roles of the staff. We could also not make comparisons with the staff who were not injured. There were a large number of non-specified injury data which made drawing conclusions about types of injuries sustained difficult. Also, whilst injuries completely unrelated to flooring were excluded, the causal mechanism in the other included injuries may or may not be related to the type of flooring. We were able to measure number of staff injured, but not the number of injuries (some staff may have sustained multiple injuries from one event). The self-reported data did not provide sufficient detail for this, but from reading the reports, multiple injuries from one event appeared rare. Data on severity or staff time off work was not provided so is a further limitation. Thus it is possible that an increased occurrence of an infrequent, but major injury such as back strain, may be missed in the general noise of all injuries. Mitigating factors include the use of both concurrent and own ward controls and with these, there was no signal to suggest an increased number of staff injured with LIF. If anything, the signal is in the opposite direction and hints that standard flooring wards may be worse than LIF for staff wellbeing.
