Tailored exercise programs can help maintain range of motion, strengthen surrounding muscles, and improve overall function. Therapists may employ stretching and strengthening exercises to counteract stiffness and promote mobility[3].

• Manual Therapy: Techniques such as massage and mobilization can be beneficial in reducing muscle tension and improving circulation, which may help alleviate some symptoms associated with ossification[4].

3. Surgical Intervention

• Surgical Resection: In cases where ossification leads to significant functional impairment or pain, surgical removal of the ossified tissue may be considered. This approach is typically reserved for severe cases where conservative treatments have failed[5].

4. Assistive Devices

• Braces and Orthotics: The use of braces or orthotic devices can help support affected muscles and joints, improving stability and function. These devices can also alleviate pain during movement[6].

5. Lifestyle Modifications

• Activity Modification: Patients are often advised to modify their activities to avoid exacerbating symptoms. This may include avoiding high-impact exercises or activities that place excessive strain on the affected muscles[7].

• Weight Management: Maintaining a healthy weight can reduce stress on the musculoskeletal system, potentially alleviating some symptoms associated with muscle ossification[8].

Conclusion

The management of other ossification of muscle (ICD-10 code M61.5) requires a multifaceted approach tailored to the individual patient's needs. While medication and physical therapy form the foundation of treatment, surgical options may be necessary in more severe cases.
