A Pilot Study of a Neural Mobilization Intervention Applied to Older Adults With Chronic Musculoskeletal Pain
Study Details
Study Description
Brief Summary
The goal of this pilot study is to evaluate the feasibility of integrating neural mobilization techniques into a multimodal physical exercise program for older adults with chronic musculoskeletal pain. The main questions it aims to answer are:
-
What is the average time to assess secondary outcomes for each participant?
-
What proportion of participants adhered and/or withdrew from the study at the end of the intervention protocol?
-
Are there adverse events/effects associated with the intervention protocol?
-
What is the level of approval/satisfaction of the participants in relation to the assessment and intervention protocols?
-
What is the impact of the intervention protocol on participants´ pain, function, physical performance, somatosensory function, and nerve excursion (secondary outcomes)?
Participants will be assessed at 3 different moments: initial assessment (T0), at the end of the intervention protocol (8 weeks) (T1) and 3 months after the end of the intervention protocol (T2). The intervention protocol will consist of a multimodal exercise program (with or without integration of neural mobilization techniques) to be carried out over a period of 8 weeks at a frequency of twice a week.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Control group The control group will perform a physical exercise program twice a week for a period of 8 weeks. |
Other: Physical Exercise Program
The physical exercise program will consist of exercises from three different exercise modalities: aerobic training, balance exercises, and isometric exercises.
|
| Experimental: Experimental group The experimental group will perform the same physical exercise program performed by participants in the control group, in addition to neural mobilization techniques twice a week for a period of 8 weeks. |
Other: Physical Exercise Program
The physical exercise program will consist of exercises from three different exercise modalities: aerobic training, balance exercises, and isometric exercises.
Other: Neural Mobilization
Neural mobilization techniques for the upper and lower quadrants will be actively performed by participants.

Outcome Measures
Primary Outcome Measures
- Dropout and adherence rates [T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Proportion of participants who adhered and withdrew from the study at the end of the intervention protocol. "Adherence to treatment" will be considered if the participant attends at least 12 sessions (75% of the total scheduled sessions).
- Adverse events and adverse effects [T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Proportion of participants that reported adverse events and adverse effects during the intervention protocol.
- Practicality [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
The average time taken to assess secondary outcomes for each participant.
- Acceptability [T1: 8 weeks (post-intervention assessment)]
The degree to which participants approve of or are satisfied with the assessment and intervention protocols. Acceptability will be assessed qualitatively through focus groups, where a recorded interview (audio only) will be carried out by the study's main researcher, in order to assess the participants' perception of the study and the intervention protocol.
Secondary Outcome Measures
- Pain severity [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Brief Pain Inventory (BPI)
- Temporal characteristics of pain [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
World Health Organization (WHO) Classification - It is a categorical variable with three different possible response categories: Episodic recurrent pain - recurrent pain attacks with pain-free intervals; Continuous pain - pain is always present; Continuous with pain attacks - recurrent pain flare-ups as exacerbations of ongoing underlying pain.
- Neuropathic pain components [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
painDETECT questionnaire - The instrument consists of 4 sections related to: (1) pain intensity in the last 4 weeks; (2) the pain pattern; (3) regions of pain; and (4) presence of neuropathic descriptors. The total score is obtained by adding the scores of the last 3 sections and can vary from 1 to 38. Scores ≤ 12 = the neuropathic mechanism is very unlikely to be present (predominance of the nociceptive mechanism); Scores ≥ 19 = there is a high probability of a predominant neuropathic mechanism; Scores > 12 and < 19 = the presence of a mixed component.
- Pain Catastrophizing [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Pain Catastrophizing Scale (PCS) - The instrument has 13 items subdivided into three different subscales: helplessness (items 1, 2, 3, 4, 5, and 12); magnification (items 6, 7, and 13); and rumination (items 8, 9, 10, and 11). All subscales are evaluated on a 5-point Likert scale, from 0 (not at all) to 4 (all the time), where higher scores represent a greater level of catastrophizing.
- Fear of Movement [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Tampa Scale for Kinesiophobia - The instrument comprises 13 items rated on a 4-point Likert scale, as follows: (1) strongly disagree; (2) somewhat disagree; (3) somewhat agree; (4) strongly agree. The higher the score, the greater the fear perceived during the execution of the movement.
- Symptoms of Central Sensitization [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Central Sensitization Inventory (CSI)
- Pressure Pain Threshold (Thenar region of the right hand; Right calcaneus; Region of greatest pain) [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Algometer
- Cold and Warm Perception Threshold ((Thenar region of the right hand; Right calcaneus; Region of greatest pain) [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Q-sense
- Lower Limb Strength [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Five Times Sit to Stand Test
- Grip Strength [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Hand-held dynamometer
- Agility and Dynamic Balance [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Timed-Up-And-Go Test
- Nerve excursion (median and tibial nerves) [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
Ultrasonography - The longitudinal and transverse excursion of the tibial and median nerves will be measured in millimeters using ultrasound images taken during the execution of a joint movement.
- Range of Motion (ankle dorsiflexion and wrist extension) [T0: baseline assessment; T1: 8 weeks (post-intervention assessment); T2: 3 months post-intervention (follow-up assessment)]
