Fulltext Biomechanics Analysis of the Firefighters' Thorax Movement on Personal Protective Equipment during Lifting Task Using Inertial Measurement Unit Motion Capture

Yunus MNH, Jaafar MH, Mohamed ASA, Azraai NZ, Amil N, Zein RM

PMID: 36361112 DOI: 10.3390/ijerph192114232

Back injury is a common musculoskeletal injury reported among firefighters (FFs) due to their nature of work and personal protective equipment (PPE). The nature of the work associated with heavy lifting tasks increases FFs' risk of back injury. This study aimed to assess the biomechanics movement of FFs on personal protective equipment during a lifting task. A set of questionnaires was used to identify the prevalence of musculoskeletal pain experienced by FFs. Inertial measurement unit (IMU) motion capture was used in this study to record the body angle deviation and angular acceleration of FFs' thorax extension. The descriptive analysis was used to analyze the relationship between the FFs' age and body mass index with the FFs' thorax movement during the lifting task with PPE and without PPE. Sixty-three percent of FFs reported lower back pain during work, based on the musculoskeletal pain questionnaire. The biomechanics analysis of thorax angle deviation and angular acceleration has shown that using FFs PPE significantly causes restricted movement and limited mobility for the FFs. As regards human factors, the FFs' age influences the angle deviation while wearing PPE and FFs' BMI influences the angular acceleration without wearing PPE during the lifting activity.

Successful Transcatheter Arterial Embolisation for a Traumatic Iliacus Hematoma: A Case Report

A traumatic iliacus hematoma is rare and usually occurs in patients after a fall involving a lower back injury. Although the hematoma may compress the femoral nerve causing femoral nerve palsy, the gold standard treatment for this condition has not been established. Here we report transcatheter arterial embolisation as a useful treatment strategy for a traumatic iliacus hematoma.

Fulltext Accidents and injuries related to powered paragliding: a cross-sectional study

Feletti F, Goin J

BMJ Open, 2014 Aug 28;4(8):e005508.
PMID: 25168039 DOI: 10.1136/bmjopen-2014-005508

OBJECTIVES: Powered paragliding (PPG) and paragliding are two totally different sports, mainly because of the use of an engine in powered paragliding. As a consequence, the pattern of injuries caused by each of these two sports may be different.
SETTING: To test this hypothesis, we analysed 384 incident reports gathered by the US Powered Paragliding Association from 1995 to 2012. The majority of the incidents occurred in the USA, while 26 incidents occurred elsewhere: Canada (8), Mexico (5), Panama (1), China (1), Japan (1), Malaysia (1), Indonesia (Java) (1), Europe (8): of which Spain (1), Belgium (1), UK (3), Italy (1), Romania (1), unknown (1).
OUTCOME: To identify the most affected body area and the most common type of injury sustained in PPG, and to highlight any differences from paragliding.
RESULTS: The most affected body areas in PPG were the upper limbs (44.5%), followed by the lower limbs (32%), the back (9.8%), the head (7%), the pelvis (3.1), the chest (2.7%) and the abdomen (0.7%) (p<0.001). The engine caused 43 accidents (11.2%) in our study and was responsible for the majority of injuries to the upper limbs. The number of fatal accidents in PPG is not lower than in paragliding and hang-gliding.
CONCLUSIONS: To help prevent the specific injuries of PPG, the most appropriate equipment should be identified. The results of this study also suggest that, in the future, this sport should be analysed separately from paragliding.

The objective of this study is to identify the type of occupational related musculoskeletal disorder among Malaysian Shipping Industry workers and to determine the relationship between workers sosio demographic factors with occupational related musculoskeletal disorder and injuries. This is a cross sectional, retrospective study using secondary data that is available at the physiotherapy centre of Malaysia Shipping in Selangor. The study population is the shipping port workers received physiotherapy treatment from 2011 and 2012. A total of 90 samples comprise of 85 male workers and the remaining is female. The mean age is 34.1 (±7.36). Crane operator is the largest number of workers seeks for physiotherapy treatment (68), office (15) and 7 from maintenance. The mean of employment duration is 8.02 (±4.47) years with the maintenance group of workers have longest working duration of 9 years. Muscle and ligament sprain strain known to be the commonest condition (80%) refer for physiotherapy rehabilitation, tendinitis (14%) and fracture (6%). Young age group of workers were significantly 9 times higher (95% CI 1.83 – 40.35) of getting back injuries. The prevalence of musculoskeletal disorder based on work categories vary with office type workers has 4.5 times higher (95% CI 1.06 – 19.7) on hand injuries. This study has revealed that workers age, different type of work categories, working experience, and body mass composition were associates with the occupational related injuries. The training programme emphasise on preventive measures should be tailored to empower the employee on safety measures at work.
