Abstract
Purpose. This study was conducted to examine the effect of pulsed electromagnetic field therapy on quadriceps muscle strength after burn injury.
Methods. From April 2021 to June 2022, sixty male patients who suffered from second degree lower limb thermal burn injury and Total body surface area (TBSA) from 25% to 35% participated in this study. Their ages ranged from (20-40) years. They were randomly assigned in two groups, a study group composed of 30 patients who received (PEMF) over thigh area before strengthening exercise for quadriceps muscle and a control group composed of 30 patients who received strengthening exercise for quadriceps muscle. Patients of both groups received traditional physical therapy program.. Evaluation tool was isokinetic dynamometer to measure the quadriceps muscle peak torque before the treatment and after 8 weeks of treatment for both groups.
Results. There was no significant difference between both group (study and control) in mean values of quadriceps peak torque pre-treatment (P > 0.05). There was a significant increase in the mean values of quadriceps peak torque after 8 weeks of treatment in both groups (p < 0.05) while there was a significant difference in post treatment mean values of quadriceps peak torque in the study group when compared with control group (p < 0.05).
Conclusion. Pulsed electromagnetic field therapy is an effective modality that can be used for improving muscle strength and performance in patients with lower limb burn when applied prior to strengthening exercise.

Haytham M. Elhafez, Sohier S. Rizkallah, Magda R. Zahran, Doaa S. Mostafa, Ahmed F Geneidy – Static Magnetic Stimulation Versus Conventional Treatment on Cross Sectional Area of Quadriceps Muscle in Knee Osteoarthritis Patients: A Randomized Controlled Study. Fizjoterapia Polska 2021; 21(2); 216-222

Abstract

Background. Quadriceps femoris muscle significantly affected knee osteoarthritic patients. Weakness and atrophy occur as a result of muscle unloading and dysfunction. As the maximum force produced by a muscle has a direct proportion to its cross-sectional area (CSA), the current study revealed that static magnetic stimulation (SMS) is beneficial for improving CSA of the quadriceps muscle. Purpose. To examine the influence of magnetic stimulation on CSA of the quadriceps muscle in knee osteoarthritis patients and hence knee function. Materials and Methods. This study adopted a randomized controlled trial design. Twenty-four patients with both knee osteoarthritis (Grades II and III) participated. The participants, aged between 45–55 years, were randomly assigned to two groups. Group (A) received magnetic first stimulation in addition to selected physical therapy consisting of ultrasound device and isometric exercise for quadriceps. Group (B) received selected physical therapy consisting of ultrasound device and isometric exercise for quadriceps only. Two therapeutic sessions were given weekly for three consecutive weeks. Outcome measures were CSA of quadriceps at both sides and Lysholm knee scoring for assessment of the functional ability of the knee joint. These measures were taken before and after three consecutive weeks of intervention. Results. Within groups, the analysis showed a statistically significant increase for all measured variables in the two studied groups (p < 0.05). Between groups, the analysis revealed that quadriceps at both side and Lyshlom were significant increase in group (A) compared to group (B). Conclusions. Adding SMS to quadriceps strengthening exercises improved the CSA of quadriceps, which protects muscle from being atrophied and hence improved the knee joint functions more than quadriceps strengthening exercises alone.

Yasmein M. Mahmoud, Wadeda H. Elsayed, Amira H. Draz – Effect of plyometrics, closed kinetic chain versus quadratus lumborum strengthening exercises on vertical jump height in volley ballplayers: A randomized controlled trial. Fizjoterapia Polska 2020; 20(3); 192-196

Abstract

Purpose. To compare the effects of plyometrics, closed kinetic chain with quadratus lumborum strengthening exercises on vertical jump height in volley ball players.

Design. Pre-post measurement randomized controlled trial.

Methods. Two hundred volleyball players were recruited from Cairo and Kafer El Sheikh University, Egypt. 140 volleyball players met the inclusion criteria and were randomly assigned into four equal groups. Group (A) consisted of 35 volley ball players with mean body mass index (BMI) value of 21 ± 3.76 kg/m2 and received plyometric exercise (Counter Movement jump (CMJ). Group (B) consisted of 35 volley ball players with mean BMI value of 21.44 ± 1.681 kg/m2 and received closed kinetic chain (CKC) exercise (double limp squat free weights), Group (C) consisted of 35 volley ball players with mean BMI value 22.17 ± 1.8 kg/m2 and received quadratus lumorum strengthening exercise (isotonic hip hiking), group (A), (B) and (C) received the exercises two times per week for eight weeks. Group (D) consisted of 35 volley ball players with mean BMI value of 22.01 ± 1.69 kg/m2 and received no exercise (control group).

Results. Statistical analysis revealed that there was significant difference (p < 0.05) in favour to group A, B and C in compared to group D. while there were no significant differences (p > 0.05) among groups (A, B and C).

Conclusion. Plyometrics (CMJ), CKC (Double limb squat free weights), and quadratus lumborum strengthening exercise (Hip hiking) yield an improvement on vertical jump height.

Stabilizacja centralna w rehabilitacji dzieci – aspekt fizjoterapeutyczny

S. Dyczewska-Wójtowicz – Core Stability in the Rehabilitation of Children – Physiotherapy Aspects. FP 2016; 16(3); 96-105

Streszczenie
Wstęp. Termin „stabilizacja centralna” (ang. core stability) odnosi się do wydolności głębokich mięśni tułowia, których rolą jest kontrola centrum naszego ciała w statyce i dynamice. Praca przedstawia różne aspekty fizjoterapeutyczne dotyczące problemu stabilizacji centralnej w ewidencji naukowej potwierdzające skuteczność ćwiczeń.
Materiał i metody. W procesie wyszukiwania artykułów korzystano z baz artykułów MedLine i PubMed oraz PBL, uwzględniając następujące słowa kluczowe: stabilizacja centralna, stabilizacja lędźwiowa, stabilizacja dynamiczna, kontrola motoryczna, trening nerwowo-mięśniowy, stabilizacja tułowia, wzmacnianie centralne.
Wyniki. Liczne badania naukowe przedstawiają fakt, iż mięśniami, które odgrywają główną rolę w tym mechanizmie, są: mięsień poprzeczny brzucha, mięsień wielodzielny, mięsień skośny wewnętrzny brzucha, mięśnie dna miednicy oraz przepona. Prawidłowo funkcjonujące tworzą rodzaj cylindra, nadając odpowiednią stabilność dla okolicy dolnego tułowia (jest bazą dla mobilności na obwodzie).
Wnioski. U dzieci z dolegliwościami bólowymi okolicy dolnego kręgosłupa mięśnie głębokie są hamowane a ich timing jest zaburzony. Najpierw napinają się duże powierzchowne mięśnie odpowiadające za wykonanie ruchu, a następnie włączają się głębokie lokalne stabilizatory centrum. Zmiana ról między grupami mięśniowymi może być źródłem problemów przeciążeniowych, dlatego też ważnym jest aby zastosować odpowiednią rehabilitację wspomagającą stabilizację centralną.
