The Relationship Between Upper Extremity Exercise Capacity, Respiratory and Peripheral Muscle Strength in Chronic Low Back Pain

The aim of the study was to evaluate the upper extremity exercise capacity of individuals with chronic low back pain and to investigate its relationship with respiratory muscle strength, peripheral muscle strength, chest expansion, pain, disability level, fear of movement and quality of life.

Treatment and study plan

Primary outcomes

  1. Upper extremity exercise capacity

    Time frame: 1st day

    It will be assessed by 6 minute pegboard and ring test.

  2. Respiratory muscle strength

    Time frame: 1st day

    Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) will be measured using a portable mouth pressure device.

  3. Peripheral muscle strength

    Time frame: 1st day

    Knee extensor, shoulder abductor and hand grip strength will be evaluated with a dynamometer.

  4. Chest expansion

    Time frame: 1st day

    Neutral, deep inspiration and deep expiration circumferences will be measured from the axillary, epigastric and subcostal regions using a tape measure.

  5. Disability level

    Time frame: 1st day

    It will be assessed with Oswestry Disability Index. High scores on the scale indicate the presence and severity of symptoms.

Secondary outcomes

  1. Kinesiophobia

    Time frame: 1st day

    It will be evaluated with the Tampa Kinesiophobia scale.The total score ranges from 17-68, with a score above 37 indicating a high degree of kinesiophobia.

  2. Quality of life

    Time frame: 1st day

    It will be evaluated with the Short Form-12 Quality of Life scale.The subscales rate health from 0 to 100, with 0 indicating poor health and 100 indicating good health.
