Design outcomes

Primary

MeasureTime frame
Pain Intensity - A block randomization schedule was created using a computer-generated random number table, which was used to allocate patients to one of the two treatment groups, Group A and Group B. Sealed opaque envelopes were used to ensure allocation concealment. Once the study physiotherapist obtained the informed consent and baseline data, the patient was given a study number, an explanation of the study and a short history and physical examination. All patients were assessed before the treatment and at the end of sessions (total of 12 sessions) along with one week follow up by an assistant physical therapist who was blind to the treatment procedures. Pain Intensity is measured by Numeric Pain Rating Scale (NPRS) which is a one-dimensional measure of pain intensity in adults including those with chronic pain. The NPRS is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0–10 integers) that best reflects the intensity of his/her pain. The common format is a horizontal bar or line.

Secondary

MeasureTime frame
Pain Pressure Threshold of Quadratus Lumborum and Gluteus Medius (PPT) - A block randomization schedule was created using a computer-generated random number table, which was used to allocate patients to one of the two treatment groups. Sealed opaque envelopes were used to ensure allocation concealment. Once the study physiotherapist obtained the informed consent and baseline data, the patient was given a study number, an explanation of the study and a short history and physical examination. All patients were assessed before the treatment and at the end of sessions (total of 12 sessions) along with one week follow up by an assistant physical therapist who was blind to the treatment procedures. Pressure Algometer A simple hand-held device used to measure pain level by determining pressure pain threshold (PPT) using a pressure transducer probe that is placed on a point. This algometer registers the force (in kilograms per square centimetre) that is recorded is usually the amount of pressure that causes pain, the PPT. Pressure pain threshold (PPT) as mentioned was measured using a pressure algometer with a dial gauge that could be set from 0 to 7.7 kg/cm2 and a rod. The end of the rod was a 1-cm-wide plastic plate; this was placed in direct contact with the marked MTrPs. Vertical pressure was adjusted to these MTrPs at a speed of 1 kg/s until the participant expressed the ?rst sensation of pain. All the participants had MTrPs in the gluteus medius and quadratus lumborum on at least one side that persisted for > 3 months. ;Back Disability Index - A block randomization schedule was created using a computer-generated random number table, which was used to allocate patients to one of the two treatment groups. Sealed opaque envelopes were used to ensure allocation concealment. Once the study physiotherapist obtained the informed consent and baseline data, the patient was given a study number, an explanation of the study and a short history and physical examination.
