Assessment of muscle strength in chronic low back pain patients: Comparison between isocinetic rehabilitation and conventional rehabilitation.

INTRODUCTION: Chronic low back pain is a public health problem in view of its functional repercussions and the functional rehabilitation is an integral part of its management. AIM: To compare the evolution of muscle strentgh of spinal extensors and flexors in chronic low back pain patients after an isokinetic rehabilitation protocol and a conventional rehabilitation one. METHOD: This was a prospective and comparative study carried out in the Physical Medicine Department of the Tunis Military Hospital over a period of 7 months. Fifty patients were included, randomly divided into two groups of 25. The first group (G1) benefited from an isokinetic rehabilitation protocol and the second one (G2) from a classic active physiotherapy. We performed a clinical (Sorensen test and Shirado test) and isokinetic evaluation of the trunk muscles before and after rehabilitation. RESULTS: The mean age of the general population was 42±8.6 years old. Clinical evaluation showed a deficit in the extensor and flexor muscles of the spine, more important in the extensors in both groups. After rehabilitation, there was a significant improvement in clinical tests of muscular endurance in G1 and G2. Isokinetic assessment showed a greater muscle deficit in the extensors in both groups. After isokinetic rehabilitation, peak torque for flexors and extensors increased by 21% and 23% respectively, power was 34% and 37% higher, and total work increased by 26% and 47%. On the other hand, the (F/E) ratios were unchanged for all three speeds. In Group 2, peak torque values for flexors and extensors increased by 22 and 15% respectively, power was higher by 31 and 23% and total work was also up by 29 and 17%, while F/E ratios were also unchanged. Group 1 showed the greatest improvement in extensor strength at 60°/s, and in power at 90°/s for the various muscles. CONCLUSION: In our study, we concluded that endurance and muscular strength improved the most after isokinetic rehabilitation.

Cerebral palsy of the child in rehabilitation environment: epidemiologic and clinical profile and therapeutic modalities.

INTRODUCTION: Cerebral palsy (CP) is a group of permanent disorders of the development of movement and posture causing activity limitation. AIM: To evaluate the epidemiological, clinical, and radiological profile of children with CP and to study the therapeutic modalities in daily clinical practice. METHOD: This was a retrospective, descriptive study, carried out in a physical medicine and rehabilitation department, including all the patients referred with the diagnosis of cerebral palsy between January 2000 and December 2016. We used pre-established records to collect data. The missing data were collected from the files of the pediatric department. To classify cerebral palsy, we used a motor impairment classification, topographic classification according to the affected limb and the GMFCS - ER. RESULTS: Fifty patients were included with a gender ratio of 1.23. The mean age of patients was 7.8 years old. The risk factors for CP were mainly represented by perinatal asphyxia (55%) and prematurity (37%). The spastic form was predominant (74%). Quadriplegia was the most severe clinical form (61%). Neuro-orthopedic deformations were found in 78% of cases. Half of the children had GMFCS score between 1 and 2. Brain MRI lesions were dominated by anoxic-ischemic sequelae (34%). Physical therapy was prescribed for all patients. The most prescribed devices were the dynamic ankle foot orthosis (60%). Baclofen was prescribed in 5% of cases and botulinum toxin injection was performed in 30% of children. CONCLUSION: The cerebral palsy defines the clinical and functional disorders caused by non-progressive developmental damage to the brain of the infant which requires a multidisciplinary management.
