Study summary

The goal of this interventional study is to investigate the efficacy of an acute bout of exercises on pain sensitivity (primary aim) and clinical pain intensity (secondary aim) among adults with Chronic Low Back Pain. The following question will be answered in this research Q1: Is acute bout of exercise effective in reducing pain among adults with Chronic Low Back Pain?

Participants who agree to participate and sign the informed consent will be randomized to one of three groups:

Group 1: Isometric exercise with neutral language and no verbal suggestion consisting of 1 rep of wall squat, 3 min or to volitional fatigue at 100° knee angle;(n=30).

Group 2: Isometric exercise with neutral language and no verbal suggestion consisting of 3 reps of wall squat, 3 min or to volitional fatigue at 100°degree knee angle, 30-sec rest between rep, ;(n=30).

Group 3 (Control group): true control (do nothing);(n=30).

Study arms

  • Experimental
    Isometric exercise-one repetition

    Isometric exercise consisting of 1 session only. The session will last for around 5 minutes which will include asking the patient to do 1 repetition of wall squat for 3 min or to volitional fatigue at 100° knee angle. Intervention: Other: Single bout of exercise

    Other: Single bout of exercise

  • Experimental
    Isometric exercise-three repetitions

    isometric exercise consisting of 1 session only. The session will last for around 10 minutes which will include asking the patient to perform 3 repetitions of wall squats (each time the exercise will be performed for 3 min or to volitional fatigue at 100°degree knee angle); the patient will be given 30-sec rest between repetitions. Intervention: Other: Single bout of exercise

    Other: Single bout of exercise

  • No intervention

Interventions

  • OtherSingle bout of exercise

    isometric wall squat at a knee joint angle of 100 degrees. Instruct participant to place their back against the wall with feet positioned parallel and spaced shoulder-width apart. Lower themselves down until they reached a knee joint angle of 100 degrees. Measure knee joint angle by placing a goniometer on the lateral epicondyle of the knee, in line with the femur whilst the anchor arm was in line with the lateral malleolus.

What researchers measure

Primary outcomes

  1. Pain pressure threshold

    The pain will be measured using digital pressure algometer, FDX®️ (Wagner instrument, Greenwich, USA). All trials will be conducted on forearm, lumbar spine and calf sites. There will be at least 20 sec rest before an individual site is tested again. Two trials will be performed at each site. The raw values of each test will be recorded. Because we are testing repeated times, we will use a marker to mark the location of each test site to ensure consistency in location. Algometer must be positioned perpendicular to the measurement site for all trials.

    Time frame: [ Time Frame: Change from pre-intervention (baseline) compared to post-intervention (immediately after session) ]

Secondary outcomes

  1. Pain intensity

    It will be assessed using Visual Analogue Scale (VAS; 0-10). A rating of zero means that participant don't currently have pain at the low back. A rating of ten on this scale means that the pain at low back is the worst pain. So, the higher the number on this scale means the higher the pain intensity participant is experiencing.
