Context: Some researchers have suggested that an alteration of stretch perception could be responsible for the success of the contract-relax (CR) stretch, a stretch technique derived from proprioceptive neuromuscular facilitation (PNF). Objective: This study was conducted to determine if the alteration of the stretch perception is a possible explanation for the range of motion (ROM) gains of the CR stretch. Participants: Eighteen subjects performed two stretches in randomized order: the slow stretch and the CR stretch. Main Outcome Measure: The stretch intensity was controlled. The stretch force was measured and compared between the slow stretch and CR stretch. Results: There …
