Clinical Trial Summary
Low back pain is a common condition that occurs in up to 70% of the population in
industrialized countries and is the second most common cause of work inability. Physiotherapy
is the usual treatment for low back pain. Recent studies showed that combining theory-based
psychological methods with physiotherapy can enhance the effectiveness of physiotherapy
treatment for people with chronic low back pain.
One promising approach to treating chronic pain is PACT - Physiotherapy informed by
Acceptance and Commitment Therapy (ACT), a form of cognitive-behavioral therapy. PACT aims to
increase psychological flexibility and focus on improving function rather than reducing pain.
According to several studies, the effects of ACT can be maintained up to 3 years
post-treatment, which is essential in a condition such as chronic pain and its typical
relapses.
According to self-determination theory (SDT), facilitating an environment of acceptance and
autonomy support enhances treatment motivation, thus offering a good interface for applying
SDT´s research concepts to ACT interventions.
The primary objective of this study is to investigate the impact of physiotherapists´
autonomy-supportive behavior within PACT on the motivation process in chronic low back pain
patients. Other objectives are to evaluate the efficacy of PACT on the functioning and
disability due to CLBP, adherence to recommended physical activity, and the acceptance of
pain.
This prospective, randomized controlled trial will include 2 treatment groups (PACT treatment
group and Usual physiotherapy Care group[UC]) in 1:1 ratio. Participants in the PACT
treatment group will undergo a physiotherapy intervention guided by ACT principles.
Participants randomized to UC will receive treatment considered suitable by their treating
physiotherapist, including exercises based on the DNS concept and manual therapy.
Regardless of group assignment, all participants will undergo 6 physiotherapy face-to-face
interventions lasting 45 minutes, each once a week.
Study outcomes will include measures of treatment motivation, perceived degree of autonomy
support within the care settings, functioning, and disability, adherence to recommended
physical activity, and acceptance of pain.
While we acknowledge the value of usual physiotherapy care, CLBP is best suited to a
biopsychosocial model for care. Further research is needed to understand which underlying
processes and components are causing the improvement.
Description:
Eligible participants will be randomly assigned to one of the treatment groups. All subjects
will undergo 6 weeks of weekly face-to-face sessions.
PACT treatment will include an initial physical assesment with feedback, identification of
value-based goals, individualized physical exercise based on the DNS concept, manual therapy,
addressing barriers and facilitators to self-management, and skills training to promote
psychological flexibility.
UC will include an initial physical assesment with feedback, treatment considered suitable by
their treating physiotherapist that will be based on exercises according to the DNS concept
and manual therapy.
The self-report questionnaires will be completed by participants at baseline and 6 weeks, all
to be completed at home.
Treatment will be provided by an experienced physiotherapist and will be conducted in a
private room.
To avoid contamination, the same clinician will deliver both PACT and UC as CBT-based methods
are sometimes employed within usual physiotherapy care.
A clinical psychologist and expert in the ACT will provide training. There will be group
face-to-face training that will last 2 days followed by self-experience group training that
will last 6 weeks (2 hours/week).
All PACT sessions will be audio-recorded to assesing treatment fidelity. Recordings will be
used for supervision. Supervisor will be a clinical psychologist experienced in ACT and will
review one tape per month.
