Summary
Lumbar spine injury evaluations in pensioners revealed significant functional deficits. Isokinetic testing confirmed abnormal musculoskeletal capacity, validating disability status in workers with lumbar injuries.
Area of Science:
- Occupational Medicine
- Rehabilitation Medicine
- Biomechanics
Background:
- Jalisco reported 13,371 lumbar spine injury disability cases in 2008.
- Most injuries were permanent, necessitating functional capacity assessments.
- Pensioners with lumbar injuries require evaluation of their lumbar spine functionality.
Purpose of the Study:
- To assess lumbar spine functionality in pensioners with lumbar injuries.
- To utilize the Oswestry questionnaire for disability percentage determination.
- To employ isokinetic evaluation for measuring musculoskeletal capacity.
Main Methods:
- A comparative study involving 20 workers with lumbar injury disability.
- Application of isokinetic exercises to evaluate musculoskeletal capacity.
- Utilized the Oswestry questionnaire to quantify the percentage of disability.
Main Results:
- Oswestry questionnaire indicated 60% average lumbar spine functionality.
- Isokinetic extension peak torque averaged 44 Nw; flexion peak torque was -75.5 Nw.
- Average and mode work fatigue were zero; average and mode power were 40 V.
Conclusions:
- Isokinetic evaluation results were abnormal in all assessed workers.
- Abnormal isokinetic findings confirmed the disability status of the workers.
- The study validated the use of isokinetic testing in assessing lumbar injury disability.
