Improvement measures and follow-up management based on the results of the musculoskeletal hazard investigation

Corrective measures and follow-up management based on the results of a musculoskeletal hazard investigation are not procedures that end with completing and storing the investigation forms. HR and safety and health managers must connect the burdensome work, reported symptoms, and work environment issues identified in the investigation results to corrective measures and follow-up verification.

short answer

After conducting a musculoskeletal risk factor survey, Which work factors were identified, which workers complained of symptoms, what corrective measures are needed, and whether the burden was actually reduced after the measures were taken. You must manage it together.

Rather than simply classifying the investigation results as “normal/inadequate,” it is advisable to analyze them by categorizing them into work posture, repetitive movements, handling of heavy loads, work speed, working hours, breaks, equipment and tool issues, and the necessity of protective gear and assistive devices.

In particular, if there are employees with symptoms or those complaining of pain or discomfort, rather than viewing the individual as the problem Determination of need for medical intervention, work adjustment, improvement of working environment, prevention of recurrence We need to review it together.

The key point is Summary of survey results → Selection of improvement priorities by burden factor → Assignment of person in charge and deadline → Implementation of corrective measures → Follow-up management of affected workers → Notification of workers → Reconfirmation in the next survey or inspection It is to create a flow.

When will it be applied?

Improvement measures and follow-up management based on the results of the musculoskeletal risk factor investigation are necessary in the following situations.

situation	Items to check by the person in charge
Regular hazardous factor survey completed	Identify burdensome work, symptom investigation results, and items requiring improvement.
Occurrence of patients with musculoskeletal disorders	Review of the necessity of ad-hoc inspections and measures to improve the working environment
Employee complained of pain/discomfort	Confirmation of medical intervention requirements, work adjustments, and follow-up care standards
Identify tasks with many repetitive movements	Review of work speed, working hours, breaks, and the necessity of rotational work
Checking heavy load handling operations	Weight display, assistive devices, two-person operation, verification of transport route
Check for improper work posture	Review of improvements to workbench height, chair, tools, and workspace
Improvement measures are incomplete	Confirm person in charge, deadline, budget, and proof of completion
The investigation results must be communicated to the workers.	Confirm the scope of sharing regarding hazardous factors, symptoms, response guidelines, and improvement plans.
Change of Personnel · Handover	Organization of survey forms, improvement management sheets, and follow-up management records for symptomatic individuals

Musculoskeletal risk factor investigation is rather than verifying results Improvement measures and follow-up management This is important. If investigations are merely repeated without follow-up improvements to the working environment or management of symptomatic workers, the same problems may recur in the next investigation.

What HR and Safety & Health Managers Should Do

1. Organize the investigation results into work units.

It is difficult to link the results of a musculoskeletal hazard survey to corrective measures if they are organized solely by department name or total score. If possible, it is recommended to organize the data by work unit, location unit, and burden factor unit.

Organization criteria	Things to check
Task name	Which burden factors were identified in which tasks
Number of workers	Number of workers performing the task
burden factors	Repetitive movements, improper posture, heavy objects, vibration, excessive force, etc.
Complaint of symptoms	Whether pain or discomfort is reported and the affected area
Risk level	Determining Improvement Priorities
Existing measures	Whether assistive devices, rest, or education are already being applied
Additional measures	Newly needed work environment improvements or work adjustments
Follow-up confirmation	Reconfirmation schedule after action

For example, instead of simply writing “Musculoskeletal strain in logistics team,” recording it as “Repetitive handling of heavy objects and back-bending postures confirmed during inbound and outbound loading operations” makes the direction for improvement clearer.

2. Specify improvement measures for each burden factor.

If burden factors are identified in the investigation results, do not stop at a "caution needed" but change it to actual improvement measures.

burden factors	Examples of improvement measures
repetitive action	Work rotation, automation equipment review, work speed adjustment
Handling heavy loads	Use of assistive devices, weight display, two-person work standard, improvement of transport routes
Inappropriate posture	Workbench height adjustment, provision of chair and footrest, change of tool location
Excessive use of force	Power tools, jigs, auxiliary devices, changes in work methods
long-term fixed posture	Provides opportunities for rest time allocation, stretching, and posture changes
cramped workspace	Streamline reorganization, relocation of storage, securing workspace
Wrist and shoulder strain	Improved handle, adjustable working height, limit on repetitive work time
Back strain	Supplementation of standards for lifts, trolleys, height adjustment equipment, and heavy load handling

It is advisable not to limit improvement measures to merely "conducting training" whenever possible. While training is necessary, measures to reduce actual burden factors, such as workbench height, handling equipment, workload, breaks, and work placement, should be considered alongside it.

3. Set improvement priorities.

If the investigation results reveal many items requiring improvement, it is difficult to implement all measures at once. In such cases, priorities must be set by considering both the risk level and feasibility.

Priority criteria	Confirmation question
Whether symptoms are reported	Have any workers complained of pain or discomfort during the work?
Exposure frequency	Is it a task that is repeated every day or for a long time?
Work intensity	Is there a heavy object, excessive force, and an uncomfortable posture simultaneously?
Number of subjects	Are there many affected workers?
History of accidents and illnesses	Have you had any past industrial accidents, sick leave, medical treatment, or near misses?
Potential for improvement	Is it possible to improve equipment, workflow, and procedures in a short period of time?
Legal and Inspection Risks	Is this an item that can be verified through inspections by relevant agencies or internal audits?

For example, if multiple employees complain of wrist pain and perform the same repetitive tasks for long periods, it is advisable to prioritize reviewing work rotation, work speed, tool improvements, and rest standards rather than simple stretching training.

4. Follow-up care for symptomatic individuals is operated separately.

During the musculoskeletal risk factor investigation, employees complaining of pain, numbness, limited movement, or decreased strength may be identified. In such cases, follow-up management standards must be established, rather than simply marking the symptoms on the survey form.

However, HR personnel or managers should not attempt a medical diagnosis on behalf of others. If symptoms recur or affect work performance, it is advisable to consult appropriate professional channels, such as health managers, occupational health personnel, or medical institutions.

Confirmation items	Post-management direction
Symptom area	Check the affected areas such as the neck, shoulders, lower back, wrists, and knees.
Severity of symptoms	Check if it affects work performance
Time of occurrence	Check if it repeats after a specific task
Work relevance	Check which tasks cause increasing discomfort.
Medical measures	Whether consultation with a health manager or guidance to a medical institution is necessary
Work coordination	Review of temporary job changes, breaks, and rotational work
Improvement of working environment	Whether equipment, tools, and work posture have been improved
Reconfirmation schedule	Confirmation of symptom changes and the effectiveness of measures after a certain period

It is advisable to explain that follow-up care for symptomatic individuals is not a procedure intended to track the individual or impose disadvantages, but rather a process aimed at preventing health hazards and reducing the workload.

5. Create an improvement measure implementation management table.

Even if the investigation results confirm the need for improvement, implementation may be delayed without a designated person in charge and a deadline. Therefore, it is recommended to create a separate management table for the implementation of corrective measures.

item	Writing example
Investigation date	2026.08.12
Task name	Logistics inbound and outbound loading operations
Identified burden factors	Repetitive handling of heavy objects, bending at the waist
Improvement measures	Review of mobile lift introduction, re-announcement of 2-person work standard
manager	Logistics Team Manager, Safety and Health Officer
Completion deadline	2026.09.10
sledding	In progress
Proof of completion	Equipment purchase request, site photos, worker instructions
Follow-up confirmation	Reconfirmation of workers' opinions during on-site inspection in October 2026

It is recommended to include supporting documents confirming completion and a schedule for follow-up verification on the implementation management sheet, rather than simply marking it as “completed.”

6. Provide workers with the investigation results and response guidelines.

The investigation of musculoskeletal hazards should not be merely data kept by the person in charge, but should lead to a process of providing necessary information to the relevant workers.

The information to be provided can be summarized as follows.

Guide Items	Content Example
Identified hazardous factors	Repetitive movements, handling of heavy objects, improper posture, etc.
Signs of musculoskeletal disorders	Pain, numbness, weakness, limited movement, etc.
How to handle the situation	Reporting channels in case of symptoms, consultation with a health manager, and guidance to medical institutions
Proper work posture	Heavy lifting posture, workbench usage, auxiliary equipment usage
Improvement measures	Completed measures and measures in progress
Additional comments path	How to submit worker feedback, near misses, and complaints

In particular, to ensure that employees do not worry about facing disadvantages when reporting symptoms, it is advisable to inform them that “notifying symptoms is not raising an issue, but a procedure for preventing health hazards.”

7. Reconfirm the effect after improvement.

A frequently overlooked aspect of follow-up management for musculoskeletal hazard surveys is verifying effectiveness. Even if equipment is replaced or training is provided, corrective measures may end up being merely perfunctory if it is not confirmed whether the burden on workers has actually decreased.

After the improvement, you can check the following items.

Verification method	Confirmation details
On-site re-inspection	Work posture, work speed, movement path, use of auxiliary equipment
Worker's opinion	Whether pain and discomfort decreased after improvement
Changes in symptoms	Whether complaints of symptoms in the same area have decreased
Check usage rate	Whether auxiliary devices or improvement equipment are actually used
Educational effects	Whether the correct work method is applied
Additional measures	Whether the following measures are necessary if improvement is insufficient
Supplementing the record	Completion photos, meeting minutes, and summary of feedback results

If the improvement measures are ineffective or not being used in the field, it is recommended to listen to the workers' feedback again and modify the measures.

Management table example

The table below provides an example of internal management that can be used to organize corrective measures and follow-up management based on the results of a musculoskeletal hazard investigation. The actual items should be adjusted to suit the industry, work characteristics, whether the work involves musculoskeletal burden, and the internal safety and health management system.

division	Management Items	Record example
Research Information	Date of investigation, work subject to investigation, person in charge of investigation	2026.08.12 / Packaging Work / Safety and Health Officer
Investigation results	Identified burden factors	Repetitive motion, wrist bending posture
Whether or not symptoms	Whether workers are reporting symptoms	There are people complaining of wrist pain
Needs improvement	Whether work environment improvement is necessary	necessary
Improvement measures	Details of specific measures	Workbench height adjustment, work cycle review
manager	Person in charge of action and cooperating department	Production Team Manager, Facility Management Team
Completion deadline	Scheduled date of action	2026.09.15
Medical measures	Health manager consultation, medical institution guidance	Health Manager Consultation Guide
Worker Guide	Information on hazardous factors and response procedures	Instructions for pre-work training
Proof of completion	Photos, educational materials, purchase history, meeting minutes	Before and after photos of workbench adjustment
Follow-up confirmation	Schedule for verifying the effectiveness of measures	October 2026 On-site verification
Storage location	Survey form, implementation management form, and supporting document path	Work Environment/Musculoskeletal System/2026

Checklist

The checklist below is for internal inspection purposes to verify that corrective measures and follow-up management based on the results of the musculoskeletal hazard investigation have been carried out without omission.

especially Identification of burden factors, designation of corrective measures, follow-up management of symptomatic individuals, verification of subsequent effects These are basic verification items. If even one of these items is not sorted out, it is recommended to address it first rather than considering the hazardous factor investigation complete.

Among all items If 3 or more are insufficient It is recommended to review not only the procedures for improving the work environment, follow-up care for symptomatic workers, worker guidance, and record keeping standards, but also the scope of simply redrawing the survey form.

Common mistakes

The first mistake is completing only the survey form and not creating a management sheet for the implementation of corrective measures. If burden factors were identified in the survey results... Connecting who will improve what and by when You must do it.

The second mistake is viewing symptom complaints as solely a personal problem. Musculoskeletal symptoms are linked to the work environment, such as work posture, repetitive movements, handling of heavy objects, work speed, and lack of rest. Since this is possible, it must be viewed in conjunction with work improvement.

The third mistake is ending follow-up care with training alone. While training on proper work posture is necessary, workbench height, assistive devices, work rotation, and break distribution are also important. Improvements to actual working conditions are being reviewed together. It must be.

The fourth mistake is not verifying the effectiveness after completing improvement measures. Even if equipment is installed, it is not used, or the burden on workers is not reduced If so, additional measures may be required.

The fifth mistake is widely sharing information about the symptomatic individual. Details such as the location of pain, health status, and whether medical facilities have been used must be handled sensitively, and the department head Sharing based on the scope required for work coordination It is good to do so.

The sixth mistake is missing the situations requiring unscheduled inspections. In cases where a worker with a musculoskeletal disorder occurs, new work or equipment is introduced, or the work environment changes... Confirmation is required separately from the regular inspection schedule. You can do it.

If EAP support is needed

Investigation of musculoskeletal hazards and improvement of the working environment are not areas that an EAP can replace. Identification of burdensome tasks, improvement of the working environment, medical measures, worker education, and record keeping must be managed in accordance with the workplace's occupational safety and health management system.

However, if pain or work burden becomes prolonged, employees may also experience anxiety, lethargy, sleep problems, job stress, and work avoidance. EAP can also be recommended as a supplementary channel in cases where psychological burden increases due to industrial accidents, long-term sick leave, or the return-to-work process.

division	role
Hazardous Factor Investigation	Verification of burden work, work posture, repetitive movements, and handling of heavy objects
Improvement of working environment	Improvement of assistive devices, facilities, workbenches, movement paths, and rest standards
Health and medical measures	Symptom check, consultation with a health manager, guidance to medical institutions
EAP counseling	Support for anxiety, job stress, and return-to-work burden caused by prolonged pain
Emergency Route	Emergency response to immediate safety risks, accidents, indications of suicide or self-harm, etc.

EAP guidance text can be used as follows.

You may utilize the EAP counseling channel if you require counseling due to musculoskeletal symptoms, anxiety during the process of industrial accidents, sick leave, or return to work, job stress, or work burden. EAP does not replace musculoskeletal hazard investigations, work environment improvements, medical judgments, or occupational safety and health measures; it is a supplementary channel designed to support the psychological well-being of employees.

However, in cases of immediate safety risks, accidents, suggestions of suicide or self-harm, or risks of violence, do not respond solely with general EAP guidance; you must first check emergency routes such as 119, 112, or the suicide prevention hotline 109.

Frequently Asked Questions

Q1. Is it mandatory to take corrective measures after the musculoskeletal risk factor investigation?
If the investigation reveals a risk of musculoskeletal disorders, measures necessary to improve the working environment must be reviewed. However, the specific methods of action may vary depending on work characteristics, risk levels, the presence of symptoms, and the workplace situation.

Q2. If an employee complains of symptoms, should it be processed as a workers' compensation claim immediately?
It cannot be assumed that complaining of symptoms immediately leads to recognition of an industrial accident. It is advisable to first assess the severity of the symptoms, the likelihood of work-relatedness, the necessity of medical intervention, and the need for improvements to the working environment, and to refer the patient to professional channels such as a health manager or medical institution if necessary.

Q3. Is it sufficient to implement improvement measures through training alone?
While training is an important measure, it is often difficult to consider it sufficient on its own. Measures to reduce actual burden factors, such as work posture, handling of heavy loads, workbench height, assistive devices, work rotation, and rest distribution, must be considered in conjunction.

Q4. Is it okay to share the symptomatic person's information with the department head?
Sharing some information may be necessary for work adjustments or improvements to the working environment. However, it is advisable to share sensitive information, such as the location of pain, health status, or medical treatment history, only to the extent necessary. It is safer to provide guidance to department heads focusing on the details required for work adjustments.

Q5. How should improvement measures be recorded if immediate action is difficult due to budget constraints?
Even if immediate action is difficult, it is advisable to record the reason for the hold, alternative measures, budget review schedule, and the timing of the next inspection. Rather than simply leaving it as "unactiond," you should manage temporary measures and the schedule for follow-up reviews together.

Q6. Is it necessary to conduct the survey again after the improvements?
While it is difficult to conclude that a full re-investigation is always necessary, it is advisable to verify whether corrective measures were actually effective. Follow-up checks can be made through on-site re-inspections, verification of worker feedback, confirmation of changes in symptoms, and inspection of assistive device usage.

Next step

Improvement measures and follow-up management based on the results of the musculoskeletal hazard investigation are not merely about storing investigation forms, but rather a process of actually changing the work environment and providing appropriate support to those exhibiting symptoms.

HR and safety and health managers should first check the following three points.

Priority check items	Confirmation details
Improvement measures	Did the burden factors identified in the investigation results lead to specific measures?
Aftercare	Are there criteria for medical measures, work adjustments, and follow-up checks for individuals reporting symptoms?
Verify the effect	Is there a schedule to re-verify whether the burden on workers has decreased after the improvements?

If you wish to comprehensively overhaul musculoskeletal hazard assessments, work environment improvements, support for industrial accidents and return to work, and psychological support for employees at the organizational level, review the operational methods suitable for your organization through a Nudge EAP implementation consultation.
