Abstract
Objectives: Comparative study of physiotherapy modalities and exercise in Low back
pain. Design: Randomized Control Trial. Methodology: 20 Participants with a history of Chronic
low back pain (CLBP) were randomly assigned into 5 groups; control group G1 (n = 4) that receive
exercises only and 4 experimental groups (each with n = 4). The experimental groups are G2
(Ultrasound + exercise), G3 (IR + exercise), G4 (TENS with hot pack + exercise), and G5 (vibration
massage + exercise). Each participant was treated 3 times weekly, for two weeks and each exercise
repeated (10 × 5) along the period of study (2 weeks ). The outcome measures used in this study
were the Oswestry Disability Questionnaire (ODQ) and the Visual Analogue Scale (VAS) both of
which were scored by all participants. Results: The VAS readings indicated a significant difference
at the 1% level (p = 0.003) between the control group and the experimental groups, and showed
highly significant in participants that treated with electric stimulation, then TENS with hot bag for 15
min. and followed by stretching and strengthening exercises as compared with the control group that
received only the exercises. Also, ODQ readings showed significant difference (p = 0.123) between
the control and treated groups. Results showed an improvement across experimental groups in pain
and disability scores. Conclusion: The results of this study showed that TENS and hot pack with
exercises have a better effect on improving pain and disability in participants suffering from CLBP.
Interestingly, the control group who had postural re-education did improve as well as the core
stability group. Age was not considered to be a factor when allocating participants into 5 groups.
However, the younger age group showed marked improvement with posture re-education and
exercise.
