Locomotive syndrome

Overview

Locomotive syndrome is a condition defined by decreased mobility due to impairment of the musculoskeletal system, including bones, joints, muscles, and nerves. It primarily affects older adults and leads to a gradual decline in the ability to walk, climb stairs, or perform other basic movements necessary for independent living. The term was introduced by the Japanese Orthopaedic Association (JOA) to highlight the importance of early detection and prevention of mobility-related decline and its associated risks, such as falls and dependence on long-term care.

Causes

Locomotive syndrome results from a variety of musculoskeletal disorders or age-related deterioration. Common contributing factors include:

• Osteoarthritis – especially of the knees and hips, leading to pain and joint stiffness

• Osteoporosis – reduced bone density increasing the risk of fractures

• Sarcopenia – age-related loss of muscle mass and strength

• Spinal disorders – such as lumbar spinal stenosis or degenerative disc disease

• Previous fractures – particularly of the hip or spine

• Neurological conditions – such as Parkinson’s disease or stroke that impair movement

• Physical inactivity – leading to deconditioning and loss of mobility

Symptoms

The symptoms of locomotive syndrome develop gradually and may be subtle in the early stages. Common signs and symptoms include:

• Difficulty walking long distances or climbing stairs

• Slower gait or shuffling steps

• Reduced balance and coordination

• Frequent falls or fear of falling

• Pain or stiffness in joints and muscles

• Difficulty standing up from a chair or getting out of bed

• Decreased participation in physical and social activities due to mobility limitations

Diagnosis

Diagnosis of locomotive syndrome involves physical assessments and questionnaires designed to evaluate mobility and functional capacity. Key diagnostic tools include:

• Stand-up test – assessing the ability to stand from a seated position at varying heights

• Two-step test – measuring stride length and balance

• 25-question Geriatric Locomotive Function Scale (GLFS-25) – a self-reported questionnaire covering mobility, pain, and daily living activities

• Physical examination – including gait and balance assessments

• Imaging studies – such as X-rays or MRI, if specific musculoskeletal disorders are suspected

Treatment

The goal of treatment for locomotive syndrome is to preserve or restore mobility and prevent further functional decline. Management includes:

• Exercise therapy – targeted strength training, balance exercises, and stretching to improve physical function

• Weight management – to reduce joint stress and improve mobility

• Pain management – using medications, physical therapy, or assistive devices

• Orthopedic interventions – such as joint injections, bracing, or surgery for conditions like severe osteoarthritis or spinal stenosis

• Fall prevention strategies – including home modifications and mobility aids

• Nutritional support – especially for managing sarcopenia and bone health

Early intervention and a multidisciplinary approach are key to successful management.

Prognosis

The prognosis of locomotive syndrome depends on the underlying causes, severity, and timing of intervention. With early detection and appropriate management, progression can often be slowed or even reversed, allowing individuals to maintain independence and avoid long-term care. However, without intervention, the condition can lead to significant disability, loss of independence, and increased risk of falls and fractures. Regular screening and physical activity are critical to preserving mobility and quality of life in older adults.
