Overall and phantom pain are well-controlled and not incapacitating Criteria for Exclusion of Subjects: 1. If MR neurogram and EMG/NCS study show nerve or muscle dysfunction/injury at a higher level than anticipated based on the appearance of the physical amputation stump, the subject may be excluded from the study due to adverse neuromuscular anatomy which would preclude use of the proposed experimental electrode implants.

• STRATUM I: Alive and in continuous first complete remission from their original cancer (leukemia/lymphoblastic lymphoma [P9404, high-risk DFCI 95-01] or Hodgkin lymphoma [P9425/P9426])
• STRATUM I: Did not have progressive disease or induction failure requiring off-protocol therapy including hematopoietic cell transplantation
• STRATUM I: Must not have been diagnosed with any subsequent malignancy that required additional cardiotoxic therapies (i.e., radiotherapy to the chest [also includes fields directed towards the neck, upper abdomen, or spine], or additional anthracyclines or anthraquinones); patients with history of subsequent malignancy that did not require such therapies remain eligible

•DRZ on P9404, P9425, P9426, and DFCI 95-01 (high risk patients only) who have relapsed or have experienced a subsequent malignancy that precludes eligibility since their original diagnosis, the study committee will review the available data (both from Children's Oncology Group's [COG?s] Statistics and Data Center [SDC] and the participating institution) to determine if individual patients are to be selected for Stratum 2; in recognition that local institutions sometimes have more updated relapse/subsequent cancer data than SDC, in cases where local data is more updated, local data will be used preferentially; the study will petition the Institutional Review Board (IRB) specifically for a waiver of consent to include any relapse and subsequent cancer data obtained from existing records for analysis of the secondary aims; patients selected for Stratum 2 will be those for whom late relapse or subsequent cancer is reported but who lack clear confirmation in existing records (either at SDC or at the local institution)

• Comparison subject must have institutional records (e.g., clinic note, treatment summary, chemotherapy roadmap) documenting lifetime receipt of 450 to 600 mg/m^2 of doxorubicin (doses within 10% are acceptable); this includes initial therapy as well as any subsequent therapy for relapse or second cancer, if relevant; as such, comparison subjects who have had osteosarcoma relapse or subsequent malignancies remain eligible so long as they meet all other eligibility criteria
• No anthracycline or anthraquinone aside from doxorubicin was ever given as part of initial or subsequent therapies
