摘要：Objective.The purpose of this research is to prove the effectiveness of the muscle strengthening techniques inregards to diminishing the symptoms of disc disorders in the lumbar spine.Methods.The group of subjects consisted of 6 patients with lumbalgia, with various social background, closeage, and professions that demand constantly their dorsal-lumbar muscles. Each subject benefited from 30 physicaltherapy sessions, conducted three times per week, with one or two days break, in order to prevent muscle and jointoverwork. They were chosen according to the following criteria: a common clinical diagnosis - lumbalgia; nocontraindications for the physical therapy treatment (heart or respiratory disorders, other types of diseases, etc.); thepatients are not in the inflammatory phase; no invalidating diseases; their agreement for the physical therapytreatment.The methods and techniques that were applied were carefully particularized and individualized according tothe patients' symptoms, both at the beginning and over the course of the treatment or sessions.The evaluation testswere the Visual Analog Scale, the joint assessment and the muscle testing.Results.The VAS results, realized through the palpation of the injured areas (ligaments and muscles) show a diminishedpain after the strengthening sessions. One can see that following the strengthening exercises, the range of motion wasalso improved by a few degrees in every direction, which represents both diminished pain reflex contractures in theextensor muscles, and a thinning of the ligament capsules. During the final testing of muscle strength, all subjectsrecorded a positive score, this aspect being the result of the analytical application of the specific musclestrengthening techniques on each muscle group. The best results recorded by the subjects were in regards to theirback muscles, the quadriceps and hamstrings, which means that at the end of the intervention, the patients were ableto easily perform eccentric contractions outside the segment, and plyometric contractions.Conclusions.The initial hypothesis was confirmed, thus an adapted and particularized strengthening programhad beneficial effects, helping to diminish the pain, reduce the contractures, maintain the strength and correct themuscle imbalances. The correct and complete evaluation of the spine, pain, and the functional status caused by theconsecutive disability in patients with lumbalgia is an important component in the rehabilitation program, for thisbeing emphasized the need to use standardized scales through which one can quantify and compare therecorded progress.
