Research progress on sarcopenia in the musculoskeletal system.

Area of Science:

• Gerontology
• Musculoskeletal Health
• Muscle Physiology

Background:

• Sarcopenia, characterized by muscle function and mass decline, is prevalent in the elderly, increasing risks of falls and fractures.
• A strong correlation exists between sarcopenia and degenerative skeletal muscle disorders due to joint mechanical imbalances and musculoskeletal factors.

Purpose of the Study:

• To review the implications of sarcopenia and its assessment methods.
• To summarize the clinical significance and mechanisms linking sarcopenia with musculoskeletal disorders like osteoporosis and osteoarthritis.
• To examine sarcopenia's impact on the efficacy of treatments for musculoskeletal conditions.

Main Methods:

• Literature review of sarcopenia and its relationship with musculoskeletal disorders.
• Critical evaluation of current sarcopenia assessment techniques.
• Synthesis of evidence on underlying mechanisms and therapeutic effects.

Main Results:

• Sarcopenia is closely associated with the development, progression, and prognosis of musculoskeletal disorders.
• Imbalances in joint mechanics and musculoskeletal secretory factors contribute to the sarcopenia-musculoskeletal disorder link.
• Sarcopenia can affect how well medications and surgeries work for bone and joint conditions.

Conclusions:

• Sarcopenia is intrinsically linked to musculoskeletal disorders, influencing their onset, progression, and outcomes.
• Further research is needed to understand the mechanisms connecting muscle loss and skeletal muscle diseases.
• Investigating sarcopenia mitigation strategies could offer new therapeutic avenues for musculoskeletal conditions.
