Outcome measures
Primary outcome
The reliability and validity of the E-cone during assessment of the hand grip
in patients with rheumatoid arthritis or hand arthrosis, and healthy
individuals.
Secondary outcome
Other questions:
1. What is the reliability (intra - and interreliability) of the clinical
assessment of the grasp pattern of patients with rheumatoid arthritis or hand
arthrosis and healthy individuals while using the E-cone?
2. What is the reliability (intra - and interreliability) of the assessment of
the pressure distribution measured by the E-cone of patients with rheumatoid
arthritis or hand arthrosis and healthy individuals?
3. What is the association between the clinical assessment of the grasp pattern
and the measured pressure distribution by the E-cone?
4. What is the association between the clinical assessment of the grasp pattern
on the one hand and the function of the hand (assessed by means of the HAQ -
grip) and the activity level (assessed by the DASH) on the other hand?
5. What is the association between the pressure distribution during grasping on
the one hand and the function of the hand (assessed by means of the HAQ - grip)
and the activity level (assessed by the DASH) on the other hand?
6. What is the association between the clinical assessment of the grasp pattern
and the digitalized output of the E-cone?
7. What is the association between the pressure distribution during grasping
and the digitalized output of the E-cone?
8. What is the association between the digitalized output of the E-cone
pressure (hand function) on the one hand and the function of the hand (assessed
by means of the HAQ - grip) and the activity level (assessed by the DASH) on
the other hand?
Background summary
Many patients with rheumatoid arthritis develop early in the development of the
disease an imbalance between the intrinsic and the extrinsic muscles of the
hand. The intrinsic muscles predominate over the extrinsic muscles. This causes
a downward spiral that eventually ends in a deformed hand. Patients with hand
arthrosis show the same imbalance between intrinsic and extrinsic muscles.
The treatment in the early fases of rheumatoid arthritis and hand athrosis
focusses on optimal hand co-ordination of the hand muscles. It is difficult to
teach patients this optimal hand coordination, as they have already taught
themselves an imbalanced hand co-ordination. It is necessary for patients to
recognize and acquire the optimal hand coordination. Correct feedback regarding
the hand coordination is essential for this purpose; for this, visualisation of
the handgrip is an essential item.
Recently a new measurement instrument had been developed, by which means the
distribution of the hand pressure can be visualized, the so-called E-cone. A
matrix of pressure sensors attached to a conus measures the pressure of the
hand. The distribution of the hand pressure can be visualized on a screen. Thus
enabling the patient to receive directly feedback on his hand pressure and
therefore on his hand grip.
It seems that a measurement instrument has been developed that has the
potential to diagnose and visualize problems in the hand co-ordination in
patients with rheumatoid arthritis of hand arthrosis. Furthermore the
instrument seems suitable as an aid in the therapy of patients with imbalanced
hand grip.
For an optimal understanding, this pilot will be performed in 2 groups with
maximum differentiation between on the one hand serious imbalanced hand grip
(in patients with reumatoid arthritis or hand arhrosis) and on the other hand
normal handgrip in healthy individuals.
Study objective
Assessment of the hand grip in patients with rheumatoid arthritis or hand
arthrosis, and healthy individuals while using the E-cone.
Study design
Observational study.
Study burden and risks
The participation of the patients with rheumatoid arthritis or hand arthrosis
in the study will take place directly after the therapy they follow in the
light of their hand problems. It consists of completing two questionnaires with
multiple choice questions and lifting the E-cone two times during three
seconds. The act of lifting the E-cone will be filmed (only the hand and
forearm will be seen on video) in order to answer the first research question.

Inclusion criteria
Group 1 patients:
Diagnosis of rheumatoid arthritis or hand arthrosis.
Patients have been referred for treatment in the hand rehabilitation team in Reade, location Jan van Breemen.

No problems with the hand, at present or in the past.
Normal grasping pattern and during physical examination, no impairments of the hands.
Exclusion criteria
Group 1:
Status after amputation of 1 or more (parts of) fingers of the hand that will be assessed.
Patients who have used the E-cone during treatment.
