Comparison of Female Geriatric Lumbar Extension Strength


    In the conducted research, the findings revealed a notable increase in range of motion (ROM) and back strength following the use of these machines. Lumbar strength was compared between healthy asymptomatic geriatric women and symptomatic geriatric females. The INJ group assessed the back strength of the two control groups using MedX lumbar extension machines.


    In the study titled “Comparison of Female Geriatric Lumbar Extension Strength: Asymptomatic Versus Chronic Low Back Pain Patients and Their Response to Active Rehabilitation, investigates the lumbar extension strength in female geriatric patients, comparing those with symptoms of low back pain and those without. Thirty-eight females ages 68 and over who were 162.7 cm and weights 66.2 +/- 10.4kg were examined. Eighteen of these women had chronic back pain and their doctors have recommended them to this rehabilitation program. The average time span of this treatment was about 97 days and 20 visits using the MedX lumbar extension machines.

    Patients experiencing back pain often neglect the utilization of their lumbar extension muscles, resulting in diminished range of motion (ROM) and strength. In this trial, all female participants utilized computerized MedX machines designed to prevent pelvic rotation during trunk extension, thereby isolating the lumbar extension for targeted exercise. Each participant underwent isometric testing to assess ROM across various angles. If any discomfort was experienced during the exercises, participants were instructed to cease immediately.

    The participant would undergo 20 controlled repetitions, and if they exceeded this count with the same weight, the subsequent session would incorporate heavier weights. Each session aimed to evaluate the patient’s range of motion (ROM) without inducing discomfort. If patients experienced reduced pain, they could adjust their rehabilitation schedule to once a week. However, if pain intensified after weekly sessions, they would revert to biweekly sessions. Lumbar strength assessments were conducted every 4 weeks. Results varied significantly between asymptomatic and symptomatic patients; however, symptomatic patients demonstrated enhanced strength and reduced pain over time.
