Brief Summary:
This randomized controlled trial aims to evaluate the effect of a single session intervention based on a nature-based stimulation program in patients with fibromyalgia

Condition or disease Intervention/treatment Phase
Fibromyalgia Other: Nature-based sensory stimuli Other: Control group intervention Not Applicable

Detailed Description:
All participants will continue to receive their usual pharmacological treatment as previously established by the Andalusian Public Health System. The intervention will comprise interaction tasks with biotic and abiotic agents for 30 minutes.

Arm Intervention/treatment
Experimental: Nature-based stimulation program
Participants will receive a single intervention with a duration of 30 minutes based on a multisensorial nature-based stimulation
Other: Nature-based sensory stimuli
A program based on stimulation using nature-based sensory stimuli will be implemented
Other Name: Biogenic sensory stimuli

Control intervention
Participants will be involved in a placebo task for 30 minutes
Other: Control group intervention
An activity based on a placebo intervention will be implemented

Primary Outcome Measures :
  1. Pain intensity [ Time Frame: Change from baseline pain intensity after 30 minutes ]
    Clinical pain intensity assessed by an 11-points Numeric Rating Scale (NRS-11) ranging from 0 to 10

  2. Cold pain thresholds [ Time Frame: Change from baseline cold pain thresholds after 30 minutes ]
    Cold pressor test will be used

  3. Punctate mechanical hyperalgesia [ Time Frame: Change from baseline mechanical hyperalgesia after 30 minutes ]
    Semmes-Weinstein monofilament (Aesthesio® Precise Tactile Sensory Evaluator, DanMic Global, LLC, San Jose, CA, USA) calibrated to bend at 300 gm (2940 mN; size 6.65; 0.1143 cm in diameter) of pressure with a response-dependent method will be used

  4. Wind-up phenomenon [ Time Frame: Change from baseline temporal summation of pain perception after 30 minutes ]
    Wind-up is a frequency- and intensity-dependent increase in the excitability of dorsal horn neuron that results in a temporal summation of pain perception.

  5. Pressure pain thresholds [ Time Frame: Change from baseline pressure pain thresholds after 30 minutes ]
    The minimum pressure force which induces pain when pressure is applied on tissues is regarded as the pressure pain threshold
