Summaries

How big of a problem is RSI?

In the Netherlands:

According to the federation of Dutch Trade Unions (FNV) 11% of all sick leave in the Netherlands is caused by conditions that are part of RSI (Federatie Nederlandse Vakbeweging, n.d.). In order to assess the seriousness of RSI in the Netherlands, we turn to TNS NIPO. This company specializes in public surveys. In this section we will use the results from the ‘national survey on working conditions’, using the editions from 2008 and 2013. These surveys are filled in by Dutch employees. Luckily for us, they include questions on RSI prevention at the workplace, and whether the participant suffers from RSI or conditions that have a similar effect on their health (chronic pain in their arms and/or hands, chronic pain in their back and neck). Let us summarize their results. We include the percentages of certain business sectors as we believe that these sectors include desk work.

In 2013 a combined total of 17.2% of 22,610 participants across all sectors answered that there were no or insufficient measures against RSI at their workplace. We believe the following sectors include desk work and are therefore important indicators for the necessity of RSI prevention. The percentages listed below are the combined sums of participants answering that there were no or insufficient measures against RSI at their workplace in their respective business sector. All data originates from van Zwieten, de Vroome, Mol, Mars, Koppes & van den Bossche (2013, p. 73).

No or insufficient measures against RSI at my workplace (2013) (N = 22,610)

• ‘Information and communication’: 28.1%
• ‘financial institutions’: 25%
• ‘business services’: 22.2%
• ‘public administration’: 22.9%
• ‘education’: 19.3%

Participants were also asked to indicate whether they suffered from one or more chronic impairments. From a sample of 22,901 participants, across all business sectors a combined total of 5.7% participants answered that they suffered from problems with their arms or hands (also caused by arthritis, rheumatism and RSI). From this same sample, across all business sectors a combined total of 10.3% answered that they suffered from problems with their back and neck (also caused by arthritis, rheumatism and RSI). The percentages listed below indicate how many participants answered that they suffered from one of the previously mentioned impairments. All data originates from Van Zwieten et al. (2013, p. 78).

Problems with arms or hands (2013) (N = 22,901)

• ‘Information and communication’: 4.5%
• ‘financial institutions’: 4.5%
• ‘business services’: 5.8%
• ‘public administration’: 6.7%
• ‘education’: 5.9%

Problems with back and neck (2013) (N = 22,901)

• ‘Information and communication’: 8.9%
• ‘financial institutions’: 8.9%
• ‘business services’: 10.6%
• ‘public administration’: 12%
• ‘education’: 10.7%

In 2008 a combined total of 19.4% of 21,469 participants across all sectors answered that there were no or insufficient measures against RSI at their workplace. The ‘Information and communication’ sector is missing from this iteration of the national survey on working conditions. The percentages listed below are the combined sums of participants answering that there were no or insufficient measures against RSI at their workplace in their respective business sector. All data originates from Koppes, de Vroome, Mol, Janssen & van den Bossche (2008, p. 70).

No or insufficient measures against RSI at my workplace (2008) (N = 21,469)

• ‘financial services’ at a combined total of 23.2%
• ‘business services’ at a combined total of 25.7%
• ‘public administration’ at a combined total of 23.5%
• ‘education’ at a combined total of 19%

Participants were also asked to indicate whether they suffered from one or more chronic impairments. From a sample of 21,208 participants, across all business sectors a combined total of 5.5% of all participants answered that they suffered from problems with their arms or hands (also caused by arthritis, rheumatism and RSI). From this same sample, across all business sectors a combined total of 10.2% answered that they suffered from problems with their back and neck (also caused by arthritis, rheumatism and RSI). The percentages listed below indicate how many participants answered that they suffered from one of the previously mentioned impairments. All data originates from Koppes et al. (2008, p. 75).

Problems with arms or hands (2008) (N = 21,208)

• ‘financial services’: 3.9%
• ‘business services’: 5.4%
• ‘public administration’: 5.2%
• ‘education’: 5.8%

Problems with back and neck (2008) (N = 21,208)

• ‘financial services’: 8.6%
• ‘business services’: 9.5%
• ‘public administration’: 11%
• ‘education’: 10.7%

In Europe:

The European Agency for Safety and Health at Work includes the disorders that are part of RSI in their definition of Work-Related Neck and Upper Limb Disorders (WRULDS). In a factsheet published in 2007 the organization claimed that “almost two thirds of EU workers report being exposed to repetitive hand and arm movements … significant risk factors for work-related neck and upper limb disorders.” (European Agency for Safety and Health at Work, 2007). Although WRULD encompasses all work (such as construction work), office work aligns with a lot of the risk factors and dangerous activities mentioned in the fact sheet. These include working in awkward positions (which can be caused by using a misadjusted desk or uncomfortable keyboard), repetitive movements (typing), and prolonged work without opportunities for rest. The fact sheet mentions that improving the layout of the workplace is a prime candidate for preventing WRULDS. Our vision for the RSI robotic desk is in line with this advice.

Sensor Technology

Biometric authentication is the security process using the unique biological characteristics of a person to verify their identity. This form of authentication is used in information security, law enforcement, the daily life of individuals etc.

The most commonly used forms of biometric authentication are fingerprint scanning and facial recognition. [1][2] An example of fingerprint scanning can be found in smartphones, millions of people worldwide unlock their smartphone every day using fingerprint scanning. Ease of access and speed are the biggest reasons behind the increasing use of this form of biometric authentication. [3] An example of facial recognition can be found in Apple’s new flagship smartphone, the iPhone X. The iPhone X uses Face ID, a facial recognition system using more than 30000 infrared dots to accurately map and read faces for authentication and can adapt to the changes of the user’s face over time. [4]

There exist two types of fingerprint scanning techniques, offline scanning and live-scanning. Offline scanning uses fingerprints that are obtained on paper to create a digital image. [5] Live-scanning uses an electronic fingerprint scanner to obtain these fingerprints, this is also the scanning technique used for biometric authentication on smartphones. Live-scanning can be done using three kinds of sensors: optical, solid-state and ultrasound. Optical sensors are by far the most common and capture the fingerprints by measuring the differences in the amount of reflected light from each position in the fingertip and constructs an image based on the reflected light. Solid-state sensors measure differences in physical properties, for differences in electrical current in the different parts of the finger, the closer the finger is to the sensor the higher the capacitance is, in the finger to construct an image of the fingerprint. [6] Ultrasound sensors, as the name implies utilises ultrasound to map the fingerprint. Using pulses of ultrasound and measuring where the pulse of ultrasound is absorbed or bounced back an depiction of the fingerprint is created. [7]

A form of authentication that provides ease of access, speed and familiarity would be of great use to an RSI preventative AI. Biometric authentication has all these qualities, making it an ideal choice of authentication for the AI.

Repetitive Strain Injury

RSI is thought to result from a continual risk of exceeding limits of “cumulative trauma load tolerance”. Painful stimulations also produce neuroplastic changes in the spinal and supraspinal nociceptive systems. RSI pain may be felt as a task-related response. (source 1)

In order to design a successful RSI prevention program, strategies have to be implemented to maintain compliance between the client and the program. Such a program can have an impact on the frequency of stretch breaks. (source 2)

RSI is a painful result of the inappropriate implementation of information technology in offices. However, RSI is also a management and organisational problem which should be approached in terms of an explicit health and safety policy. (source 3)

RSI is one of the main causes of lost working days. RSI requires a large amount of changes and preventive actions. (source 4)

The current strategy for RSI prevention breakdowns in the process is a risk factor for RSI. Technological systems are a potentially promising means for accident prevention, monitoring, detection and post-incident learning. (source 5)

Considering warnings, a computer warning led leads to the most correct position adjustments. The effect of the computer warning is caused by heightened attention for intervention. Warnings may be able to successfully replace educational brochures to produce behavioural changes. (source 6)

Dutch Arbo legislation

We are interested in researching RSI with respect to working life in the Netherlands. As such it seemed useful to include Dutch legislation regarding working conditions in the state-of-the-art literature study, as our design/prototype would have to comply with this legislation. In order to keep employees safe, the Dutch government introduced the working-conditions-legislation; the Arbowet (Arbowetgeving, n.d.). The Arbowet consists of three levels of legislation. The Arbowet itself offers the basis of the legislation, and contains general conditions for all working places. The Arbobesluit implements the core of the Arbowet into rules that both employers and employees should obey. The last level consists of the Arboregeling, which builds on the Arbobesluit and offers concrete regulation. The Arboregeling includes demands for work equipment.

Employers should minimize health risks for their employees, this can be done by replacing work equipment by more work-friendly alternatives (e.g. replace loud machinery with a quieter model). The working space should adapt as much as possible to the individual properties of the employees. The employers should also minimize the amount of monotonous work. Employees should also provide adequate training to their employees to for instance make better use of the work equipment.

Existing products

The Dutch RSI Vereniging is an association that focusses on providing information about the effects of RSI and how it can be prevented. They also provide a rundown of possibilities regarding the setup of the working environment in order to prevent RSI (inrichting werkplek, n.d.). Backshop is a distributor of ergonomic office space working equipment. By investigating their catalogue it appears that ergonomic office design focusses on using the following equipment:

• using ergonomically shaped mice and keyboards,
• using fully adjustable office chairs,
• using height adjustable desks, and
• mounting monitors to movable monitor arms

The Altwork Station (Specs, n.d.) integrates a monitor, desk and chair into a single unit. Every component is hinged, meaning that the user can adjust all components of the desk when the integrated seat is reclined. The user can specify 5 desks positions that can be stored, which allows the desk to change layout (e.g. from standing desk to sitting desk) with the use of a single button. Obutto is another company that distributes all-in-one ergonomic desks. Their design focusses on having a reclined chair, which spreads the user’s weight over their lower back and thighs. Their design features multiple movable platforms, which can be used to place a keyboard or mouse. These platforms can also be swiveled such that they can be used to make notes or draw. An early ergonomic desk design can be found in a patent by Nagy & Foris (1992), which describes a height adjustable desk with a rotating keyboard assembly. According to Nagy et al., their design allows the user to use their keyboard in the most comfortable way. They note that the cervical spine should be relaxed, and the computer monitor should be at eye level (Nagy & Foris, 1992, col. 7).
