PNF Versus Cryotherapy in Delayed Onset Muscle Soreness

13 juni 2026 uppdaterad av: Sara Perpiñá, Universidad Pontificia de Salamanca

Efficacy of Proprioceptive Neuromuscular Facilitation Versus Cryotherapy and Placebo on Delayed Onset Muscle Soreness: A Randomized Pilot Clinical Trial

This randomized, double-blind, single-center pilot clinical trial evaluated three interventions for delayed onset muscle soreness in the hamstring muscles.

Twenty-nine untrained adults were included. Delayed onset muscle soreness was induced using two eccentric hamstring exercises. Participants were then assigned to one of three groups: proprioceptive neuromuscular facilitation, local cryotherapy, or placebo consisting of water with sugar.

The main outcome was pressure pain threshold in the hamstring muscles. Other outcomes included knee range of motion, hamstring strength, pain intensity, perceived exertion, and blood lactate levels. Measurements were taken before the eccentric exercise, 24 hours after exercise before treatment, immediately after treatment, and 48 hours after exercise.

Intervention / Behandling
Experimentell: Proprioceptive Neuromuscular Facilitation
Participants received a proprioceptive neuromuscular facilitation intervention targeting the hamstring muscles 24 hours after eccentric exercise-induced delayed onset muscle soreness.
A contract-relax-antagonist-contract proprioceptive neuromuscular facilitation technique was applied to the hamstring muscles. The protocol included isometric hamstring contraction, rest, quadriceps contraction, and passive movement into a deeper hamstring stretch. The protocol was repeated twice on each leg.
Experimentell: Cryotherapy
Participants received local cryotherapy over the hamstring muscles 24 hours after eccentric exercise-induced delayed onset muscle soreness.
Participants were placed in prone position and an ice pack was applied over the hamstring muscles for 20 minutes. A thin cloth was placed between the ice pack and the skin to avoid direct contact.
Placebo-jämförare: water with sugar
Participants received a placebo intervention consisting of water with sugar 24 hours after eccentric exercise-induced delayed onset muscle soreness.
Participants consumed 200 mL of water with 5 g of dissolved sugar after the eccentric exercise protocol.

Åtgärdsbeskrivning
Tidsram
Change in Pressure Pain Threshold in the Hamstring Muscles
Tidsram: Baseline, 24 hours after eccentric exercise before treatment, immediately after treatment, and 48 hours after eccentric exercise
Pressure pain threshold was assessed using a pressure algometer over three points of maximum pain in the hamstring muscles. Three measurements were taken and the mean value was calculated.
Baseline, 24 hours after eccentric exercise before treatment, immediately after treatment, and 48 hours after eccentric exercise

Change in Active Knee Range of Motion
Tidsram: Baseline, 24 hours after eccentric exercise before treatment, immediately after treatment, and 48 hours after eccentric exercise
Active knee flexion and extension range of motion were assessed using a manual goniometer.
Baseline, 24 hours after eccentric exercise before treatment, immediately after treatment, and 48 hours after eccentric exercise
Change in Hamstring Muscle Strength
Tidsram: Baseline, 24 hours after eccentric exercise before treatment, immediately after treatment, and 48 hours after eccentric exercise
Maximum hamstring strength was assessed using a handheld dynamometer.
Baseline, 24 hours after eccentric exercise before treatment, immediately after treatment, and 48 hours after eccentric exercise
Change in Blood Lactate Concentration
Tidsram: Before exercise, immediately after exercise, and 48 hours after exercise
Blood lactate concentration was measured using a Lactate Edge device.
Before exercise, immediately after exercise, and 48 hours after exercise
Change in Pain Intensity
Tidsram: Baseline, 24 hours after eccentric exercise before treatment, immediately after treatment, and 48 hours after eccentric exercise
Pain intensity was assessed using the 11-point Numeric Pain Rating Scale. Scores range from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity and therefore a worse outcome.
Baseline, 24 hours after eccentric exercise before treatment, immediately after treatment, and 48 hours after eccentric exercise
Perceived Exertion After Eccentric Exercise
Tidsram: Immediately after eccentric exercise
Perceived exertion was assessed using the Modified Borg Rating of Perceived Exertion Scale after completion of the eccentric exercise protocol. Scores range from 0 to 10, where 0 indicates no exertion and 10 indicates maximal exertion. Higher scores indicate greater perceived exertion and therefore a worse outcome.
Immediately after eccentric exercise
