Sensorimotor and balance function in older adults with lumbar nerve root compression

Area of Science:

• Gerontology
• Neurology
• Biomechanics

Background:

• Lumbar nerve root compression can affect sensorimotor function and balance in older adults.
• Understanding these effects is crucial for effective clinical management and rehabilitation.

Purpose of the Study:

• To investigate the impact of lumbar nerve root compression on sensorimotor status and balance control in older adults.
• To compare sensorimotor and balance parameters between healthy older adults and those with lumbar nerve root compression.

Main Methods:

• Evaluated sensorimotor function including vibration sense, joint motion sense, and lower leg strength.
• Assessed static, dynamic, and functional balance using center of pressure measures and the Berg Balance Scale.
• Compared data between a group of healthy older adults and older adults with lumbar nerve root compression (n=17 each).

Main Results:

• Patients exhibited significantly weaker leg strength and poorer functional balance.
• Increased center of pressure motion during quiet standing and slower center of pressure motion were observed in patients.
• Reduced forward reach distance was noted in the patient group, with no significant sensory deterioration found.

Conclusions:

• Older adults with lumbar nerve root compression demonstrate impaired leg strength and balance control.
• These deficits impact static, dynamic, and functional balance abilities.
• Clinical assessment for patients with lumbar nerve root compression should comprehensively include strength and balance evaluations.
