Wikipedia: Progressive muscle relaxation
Encyclopedia overview of Jacobson’s tense–relax method, common muscle-group sequences, and clinical/population applications—navigation and vocabulary only.
Technique scaffold
Explains two-step tense then release cycles, typical cephalad vs caudad sequencing options, and 5 s hold / 10–15 s release style instructions common in consumer handouts.
Evidence boundary
PSQI points, pooled SMDs, and comparator-specific effect sizes belong to PubMed-linked systematic reviews on this wiki (e.g., PMID 41633054), not Wikipedia prose.
Distinct modalities
Article contrasts PMR with autogenic training, biofeedback, and yoga nidra—each is a separate protocol family in this database when trial evidence is indexed.
