The Effects of an eight weeks selective corrective exercises program on the worker's productivity with the upper crossed syndrome – a randomized controlled trial
The Effects of an eight weeks selective corrective exercises program on the worker's productivity with the upper crossed syndrome
Design
Clinical trial with control group, with parallel groups, double-blind, randomized, on 48 participants. Lottery was used for randomization.
Settings and conduct
50 employees of a company in Arak participated in this study according to the entry criteria. Subjects were randomly divided into experimental and control groups by lottery. The experimental group participated in training for 8 weeks. The control group had their usual life routine. Occupational productivity and UCS were evaluated at the beginning and after the completion of the intervention in the subjects. The evaluations were carried out at the Arak University laboratory in the Markazi province.
Participants/Inclusion and exclusion criteria
Inclusion criteria included forward head less than 46 degrees, rounded shoulders more than 52 degrees, kyphosis more than 42 degrees, informed consent of the participants, age range of 20-55 years, and non-pregnancy of female participants.
Exclusion criteria included recent surgical interventions on the head, neck, shoulder or spine of the participants and people with physical limitations or severe disabilities.
Intervention groups
These exercises were based on established protocols for UCS modification and were designed for muscle groups involved in the syndrome, such as the forward head, rounded shoulder, and kyphosis. The intervention program was carried out for eight weeks with three weekly sessions. Each training session lasted approximately 50 minutes. The exercises were done under the supervision of trained trainers and under the supervision. A standard warm-up and cool-down routine was performed at the beginning and end of each session, respectively. The control group did not receive any specific intervention.

Randomization (investigator's opinion)
Randomized
Randomization description
To ensure the unbiased allocation of participants, the randomization process was done by lottery. Participants who met the inclusion criteria were placed in two intervention groups or control groups. Allocation concealment was implemented using sequentially numbered, opaque, and sealed envelopes. Each envelope contained a sheet showing the group assignment. Before the study, all envelopes were prepared and sealed by an independent researcher who was not involved in participant recruitment or data collection. After obtaining informed consent, participants were enrolled in the study and envelopes were opened sequentially to determine group assignment. Participants were then informed about their assigned group. The procedure was conducted by a researcher who was not involved in the recruitment or assessment of participants.
Blinding (investigator's opinion)
Double blinded
Blinding description
The outcome assessor was trained to conduct assessments in a standardized manner. Outcome measures were used objectively to reduce subjectivity and bias, which included a standard questionnaire, objective measurement of kyphosis, round shoulder, and forward overturning. The outcome assessor was unaware of which participants belonged to the intervention or control group. The evaluator was asked not to talk to the participants more than the explanations needed to perform the tests and they were not allowed to ask the subjects questions about the study.
The analyzer was not aware of the participants' group assignments, and the information of the groups was provided to the analyzer with code 1 and 2 for the groups and a specific code for each participant.

Intervention groups
1
Description
Intervention group: In the experimental group, participants received a selective corrective exercise program designed to address musculoskeletal abnormalities associated with upper crossed syndrome (UCS). The training program consisted of stretching, strengthening, and stabilization exercises. The exercises were based on established protocols and recommendations for correcting UCS and were tailored to target specific muscle groups involved in the syndrome, such as the forward head (FH), round shoulder (RS), and kyphosis (KY).The intervention program was conducted for a duration of eight weeks, with three sessions per week. Each training session lasted approximately 50 minutes. The exercises were performed under the guidance of trained instructors and were supervised by the research team. Standard warm-up and cool-down routines were implemented at the beginning and end of each session, respectively. The program progression involved different phases. The initial phase, lasting two weeks, focused on gradually increasing the duration of exercise holds, ranging from seven sets of 10 seconds hold to 10 sets of 15 seconds hold. In the improvement phase, lasting several weeks, the activities were performed with increasing repetitions, starting from five sets of ten repetitions and progressing to six sets of 15 repetitions. Finally, the maintenance phase, which spanned the last two weeks of the program, with the aim of maintaining the achieved progress, the exercises were performed at a constant level.
