Sitting-related sacral pain affects nearly half of patients with sacral metastases and is linked to spinal instability. Early identification is crucial for effective rehabilitation and palliative care planning.
Area of Science:
- Oncology
- Rehabilitation Medicine
- Palliative Care
Background:
- Sacral metastases are rare but significantly impact patient function due to pain, neurological deficits, and instability.
- Sitting-related sacral pain is a common clinical observation but lacks systematic investigation.
Purpose of the Study:
- To determine the prevalence of sitting-related sacral pain in patients with sacral metastases.
- To examine the association between sitting-related sacral pain, spinal instability, and neurological symptoms.
Main Methods:
- Retrospective cross-sectional study of 71 patients with symptomatic sacral metastases undergoing inpatient rehabilitation.
- Sitting-related sacral pain defined as NRS ≥4 during sitting. Spinal Instability Neoplastic Score (SINS) assessed for instability.
- Associations analyzed using Firth's penalized logistic regression.
Main Results:
- 45% of patients (32/71) reported sitting-related sacral pain.
- Higher SINS scores were independently associated with sitting-related sacral pain (aOR 1.56, p < 0.001).
- Neurological symptoms were not significantly associated with sitting-related sacral pain.
Conclusions:
- Sitting-related sacral pain is prevalent in sacral metastases patients and correlates with spinal instability.
- Early identification of this pain is vital for guiding rehabilitation and palliative care.
- Activity modification and supportive care planning should incorporate findings on sitting-related pain.
